Service from afarДистанционный сервисABB’s Remote Service concept is revolutionizing the robotics industryРазработанная АББ концепция дистанционного обслуживания Remote Service революционизирует робототехникуABB robots are found in industrial applications everywhere – lifting, packing, grinding and welding, to name a few. Robust and tireless, they work around the clock and are critical to a company’s productivity. Thus, keeping these robots in top shape is essential – any failure can lead to serious output consequences. But what happens when a robot malfunctions?Роботы АББ используются во всех отраслях промышленности для перемещения грузов, упаковки, шлифовки, сварки – всего и не перечислить. Надежные и неутомимые работники, способные трудиться день и ночь, они представляют большую ценность для владельца. Поэтому очень важно поддерживать их в надлежащей состоянии, ведь любой отказ может иметь серьезные последствия. Но что делать, если робот все-таки сломался?ABB’s new Remote Service concept holds the answer: This approach enables a malfunctioning robot to alarm for help itself. An ABB service engineer then receives whole diagnostic information via wireless technology, analyzes the data on a Web site and responds with support in just minutes. This unique service is paying off for customers and ABB alike, and in the process is revolutionizing service thinking.Ответом на этот вопрос стала новая концепция Remote Service от АББ, согласно которой неисправный робот сам просит о помощи. C помощью беспроводной технологии специалист сервисной службы АББ получает всю необходимую диагностическую информацию, анализирует данные на web-сайте и через считанные минуты выдает рекомендации по устранению отказа. Эта уникальная возможность одинаково ценна как для заказчиков, так и для самой компании АББ. В перспективе она способна в корне изменить весь подход к организации технического обслуживания.Every minute of production downtime can have financially disastrous consequences for a company. Traditional reactive service is no longer sufficient since on-site service engineer visits also demand great amounts of time and money. Thus, companies not only require faster help from the service organization when needed but they also want to avoid disturbances in production.Каждая минута простоя производства может привести к губительным финансовым последствиям. Традиционная организация сервиса, предусматривающая ликвидацию возникающих неисправностей, становится все менее эффективной, поскольку вызов сервисного инженера на место эксплуатации робота сопряжен с большими затратами времени и денег. Предприятия требуют от сервисной организации не только более быстрого оказания помощи, но и предотвращения возможных сбоев производства.In 2006, ABB developed a new approach to better meet customer’s expectations: Using the latest technologies to reach the robots at customer sites around the world, ABB could support them remotely in just minutes, thereby reducing the need for site visits. Thus the new Remote Service concept was quickly brought to fruition and was launched in mid-2007. Statistics show that by using the system the majority of production stoppages can be avoided.В 2006 г. компания АББ разработала новый подход к удовлетворению ожиданий своих заказчиков. Использование современных технологий позволяет специалистам АББ получать информацию от роботов из любой точки мира и в считанные минуты оказывать помощь дистанционно, в результате чего сокращается количество выездов на место установки. Запущенная в середине 2007 г. концепция Remote Service быстро себя оправдала. Статистика показывает, что её применение позволило предотвратить большое число остановок производства.Reactive maintenance The hardware that makes ABB Remote Service possible consists of a communication unit, which has a function similar to that of an airplane’s so-called black box 1. This “service box” is connected to the robot’s control system and can read and transmit diagnostic information. The unit not only reads critical diagnostic information that enables immediate support in the event of a failure, but also makes it possible to monitor and analyze the robot’s condition, thereby proactively detecting the need for maintenance.Устранение возникающих неисправностей Аппаратное устройство, с помощью которого реализуется концепция Remote Service, представляет собой коммуникационный блок, работающий аналогично черному ящику самолета (рис. 1). Этот блок считывает диагностические данные из контроллера робота и передает их по каналу GSM. Считывается не только информация, необходимая для оказания немедленной помощи в случае отказа, но и сведения, позволяющие контролировать и анализировать состояние робота для прогнозирования неисправностей и планирования технического обслуживания.If the robot breaks down, the service box immediately stores the status of the robot, its historical data (as log files), and diagnostic parameters such as temperature and power supply. Equipped with a built-in modem and using the GSM network, the box transmits the data to a central server for analysis and presentation on a dedicated Web site. Alerts are automatically sent to the nearest of ABB’s 1,200 robot service engineers who then accesses the detailed data and error log to analyze the problem.При поломке робота сервисный блок немедленно сохраняет данные о его состоянии, сведения из рабочего журнала, а также значения диагностических параметров (температура и характеристики питания). Эти данные передаются встроенным GSM-модемом на центральный сервер для анализа и представления на соответствующем web-сайте. Аварийные сообщения автоматически пересылаются ближайшему к месту аварии одному из 1200 сервисных инженеров-робототехников АББ, который получает доступ к детальной информации и журналу аварий для анализа возникшей проблемы.A remotely based ABB engineer can then quickly identify the exact fault, offering rapid customer support. For problems that cannot be solved remotely, the service engineer can arrange for quick delivery of spare parts and visit the site to repair the robot. Even if the engineer must make a site visit, service is faster, more efficient and performed to a higher standard than otherwise possible.Специалист АББ может дистанционно идентифицировать отказ и оказать быструю помощь заказчику. Если неисправность не может быть устранена дистанционно, сервисный инженер организовывает доставку запасных частей и выезд ремонтной бригады. Даже если необходимо разрешение проблемы на месте, предшествующая дистанционная диагностика позволяет минимизировать объем работ и сократить время простоя.Remote Service enables engineers to “talk” to robots remotely and to utilize tools that enable smart, fast and automatic analysis. The system is based on a machine-to-machine (M2M) concept, which works automatically, requiring human input only for analysis and personalized customer recommendations. ABB was recognized for this innovative solution at the M2M United Conference in Chicago in 2008 Factbox.Remote Service позволяет инженерам «разговаривать» с роботами на расстоянии и предоставляет в их распоряжение интеллектуальные средства быстрого автоматизированного анализа. Система основана на основе технологии автоматической связи машины с машиной (M2M), где участие человека сводится к анализу данных и выдаче рекомендаций клиенту. В 2008 г. это инновационное решение от АББ получило приз на конференции M2M United Conference в Чикаго (см. вставку).Proactive maintenanceRemote Service also allows ABB engineers to monitor and detect potential problems in the robot system and opens up new possibilities for proactive maintenance.Прогнозирование неисправностейRemote Service позволяет инженерам АББ дистанционно контролировать состояние роботов и прогнозировать возможные неисправности, что открывает новые возможности по организации профилактического обслуживания.The service box regularly takes condition measurements. By monitoring key parameters over time, Remote Service can identify potential failures and when necessary notify both the end customer and the appropriate ABB engineer. The management and storage of full system backups is a very powerful service to help recover from critical situations caused, for example, by operator errors.Сервисный блок регулярно выполняет диагностические измерения. Непрерывно контролируя ключевые параметры, Remote Service может распознать потенциальные опасности и, при необходимости, оповещать владельца оборудования и соответствующего специалиста АББ. Резервирование данных для возможного отката является мощным средством, обеспечивающим восстановление системы в критических ситуациях, например, после ошибки оператора.The first Remote Service installation took place in the automotive industry in the United States and quickly proved its value. The motherboard in a robot cabinet overheated and the rise in temperature triggered an alarm via Remote Service. Because of the alarm, engineers were able to replace a faulty fan, preventing a costly production shutdown.Первая система Remote Service была установлена на автозаводе в США и очень скоро была оценена по достоинству. Она обнаружила перегрев материнской платы в шкафу управления роботом и передала сигнал о превышении допустимой температуры, благодаря чему инженеры смогли заменить неисправный вентилятор и предотвратить дорогостоящую остановку производства.MyRobot: 24-hour remote access
Having regular access to a robot’s condition data is also essential to achieving lean production. At any time, from any location, customers can verify their robots’ status and access maintenance information and performance reports simply by logging in to ABB’s MyRobot Web site. The service enables customers to easily compare performances, identify bottlenecks or developing issues, and initiate the mostСайт MyRobot: круглосуточный дистанционный доступДля того чтобы обеспечить бесперебойное производство, необходимо иметь регулярный доступ к информации о состоянии робота. Зайдя на соответствующую страницу сайта MyRobot компании АББ, заказчики получат все необходимые данные, включая сведения о техническом обслуживании и отчеты о производительности своего робота. Эта услуга позволяет легко сравнивать данные о производительности, обнаруживать возможные проблемы, а также оптимизировать планирование технического обслуживания и модернизации. С помощью MyRobot можно значительно увеличить выпуск продукции и уменьшить количество выбросов.Award-winning solutionIn June 2008, the innovative Remote Service solution won the Gold Value Chain award at the M2M United Conference in Chicago. The value chain award honors successful corporate adopters of M2M (machine–to-machine) technology and highlights the process of combining multiple technologies to deliver high-quality services to customers. ABB won in the categoryof Smart Services.Приз за удачное решениеВ июне 2008 г. инновационное решение Remote Service получило награду Gold Value Chain (Золотая цепь) на конференции M2M United Conference в Чикаго. «Золотая цепь» присуждается за успешное масштабное внедрение технологии M2M (машина – машина), а также за достижения в объединении различных технологий для предоставления высококачественных услуг заказчикам. АББ одержала победу в номинации «Интеллектуальный сервис».Case study: Tetley Tetley GB Ltd is the world’s second-largest manufacturer and distributor of tea. The company’s manufacturing and distribution business is spread across 40 countries and sells over 60 branded tea bags. Tetley’s UK tea production facility in Eaglescliffe, County Durham is the sole producer of Tetley tea bags 2.Пример применения: Tetley Компания TetleyGB Ltd является вторым по величине мировым производителем и поставщиком чая. Производственные и торговые филиалы компании имеются в 40 странах, а продукция распространяется под 60 торговыми марками. Чаеразвесочная фабрика в Иглсклифф, графство Дарем, Великобритания – единственный производитель чая Tetley в пакетиках (рис. 2).ABB offers a flexible choice of service agreements for both new and existing robot installations, which can help extend the mean time between failures, shorten the time to repair and lower the cost of automated production.Предлагаемые АББ контракты на выполнение технического обслуживания как уже имеющихся, так и вновь устанавливаемых роботов, позволяют значительно увеличить среднюю наработку на отказ, сократить время ремонта и общую стоимость автоматизированного производства.Robots in the plant’s production line were tripping alarms and delaying the whole production cycle. The spurious alarms resulted in much unnecessary downtime that was spent resetting the robots in the hope that another breakdown could be avoided. Each time an alarm was tripped, several hours of production time was lost. “It was for this reason that we were keen to try out ABB’s Remote Service agreement,” said Colin Trevor, plant maintenance manager.Установленные в технологической линии роботы выдавали аварийные сигналы, задерживающие выполнение производственного цикла. Ложные срабатывания вынуждали перезапускать роботов в надежде предотвратить возможные отказы, в результате чего после каждого аварийного сигнала производство останавливалось на несколько часов. «Именно поэтому мы решили попробовать заключить с АББ контракт на дистанционное техническое обслуживание», – сказал Колин Тревор, начальник технической службы фабрики.To prevent future disruptions caused by unplanned downtime, Tetley signed an ABB Response Package service agreement, which included installing a service box and system infrastructure into the robot control systems. Using the Remote Service solution, ABB remotely monitors and collects data on the “wear and tear” and productivity of the robotic cells; this data is then shared with the customer and contributes to smooth-running production cycles.Для предотвращения ущерба в результате незапланированных простоев Tetley заключила с АББ контракт на комплексное обслуживание Response Package, согласно которому системы управления роботами были дооборудованы сервисными блоками с необходимой инфраструктурой. С помощью Remote Service компания АББ дистанционно собирает данные о наработке, износе и производительности роботизированных модулей. Эти данные предоставляются заказчику для оптимизации загрузки производственного оборудования.Higher production uptimeSince the implementation of Remote Service, Tetley has enjoyed greatly reduced robot downtime, with no further disruptions caused by unforeseen problems. “The Remote Service package has dramatically changed the plant,” said Trevor. “We no longer have breakdown issues throughout the shift, helping us to achieve much longer periods of robot uptime. As we have learned, world-class manufacturing facilities need world-class support packages. Remote monitoring of our robots helps us to maintain machine uptime, prevent costly downtime and ensures my employees can be put to more valuable use.”Увеличение полезного времениС момента внедрения Remote Service компания Tetley была приятно удивлена резким сокращением простоя роботов и отсутствием незапланированных остановок производства. «Пакет Remote Service резко изменил ситуацию на предприятии», – сказал Тревор. «Мы избавились от простоев роботов и смогли резко увеличить их эксплуатационную готовность. Мы поняли, что для производственного оборудования мирового класса необходим сервисный пакет мирового класса. Дистанционный контроль роботов помогает нам поддерживать их в рабочем состоянии, предотвращать дорогостоящие простои и задействовать наш персонал для выполнения более важных задач».Service accessRemote Service is available worldwide, connecting more than 500 robots. Companies that have up to 30 robots are often good candidates for the Remote Service offering, as they usually have neither the engineers nor the requisite skills to deal with robotics faults themselves. Larger companies are also enthusiastic about Remote Service, as the proactive services will improve the lifetime of their equipment and increase overall production uptime.Доступность сервисаСеть Remote Service охватывает более 700 роботов по всему миру. Потенциальными заказчиками Remote Service являются компании, имеющие до 30 роботов, но не имеющие инженеров и техников, способных самостоятельно устранять их неисправности. Интерес к Remote Service проявляют и более крупные компании, поскольку они заинтересованы в увеличении срока службы и эксплуатационной готовности производственного оборудования.In today’s competitive environment, business profitability often relies on demanding production schedules that do not always leave time for exhaustive or repeated equipment health checks. ABB’s Remote Service agreements are designed to monitor its customers’ robots to identify when problems are likely to occur and ensure that help is dispatched before the problem can escalate. In over 60 percent of ABB’s service calls, its robots can be brought back online remotely, without further intervention.В условиях современной конкуренции окупаемость бизнеса часто зависит от соблюдения жестких графиков производства, не оставляющих времени для полномасштабных или периодических проверок исправности оборудования. Контракт Remote Service предусматривает мониторинг состояния роботов заказчика для прогнозирования возможных неисправностей и принятие мер по их предотвращению. В более чем 60 % случаев для устранения неисправности достаточно дистанционной консультации в сервисной службе АББ, дальнейшего вмешательства не требуется.ABB offers a flexible choice of service agreements for both new and existing robot installations, which helps extend the mean time between failures, shorten the time to repair and lower the total cost of ownership. With four new packages available – Support, Response, Maintenance and Warranty, each backed up by ABB’s Remote Service technology – businesses can minimize the impact of unplanned downtime and achieve improved production-line efficiency.Компания АББ предлагает гибкий выбор контрактов на выполнение технического обслуживания как уже имеющихся, так и вновь устанавливаемых роботов, которые позволяют значительно увеличить среднюю наработку на отказ, сократить время ремонта и эксплуатационные расходы. Четыре новых пакета на основе технологии Remote Service – Support, Response, Maintenance и Warranty – позволяют минимизировать внеплановые простои и значительно повысить эффективность производства.The benefits of Remote Sevice are clear: improved availability, fewer service visits, lower maintenance costs and maximized total cost of ownership. This unique service sets ABB apart from its competitors and is the beginning of a revolution in service thinking. It provides ABB with a great opportunity to improve customer access to its expertise and develop more advanced services worldwide.Преимущества дистанционного технического обслуживания очевидны: повышенная надежность, уменьшение выездов ремонтных бригад, уменьшение затрат на обслуживание и общих эксплуатационных расходов. Эта уникальная услуга дает компании АББ преимущества над конкурентами и демонстрирует революционный подход к организации сервиса. Благодаря ей компания АББ расширяет доступ заказчиков к опыту своих специалистов и получает возможность более эффективного оказания технической помощи по всему миру.Тематики

50 near cash
!гос. фин. The resource budget contains a separate control total for “near cash” expenditure, that is expenditure such as pay and current grants which impacts directly on the measure of the golden rule.This paper provides background information on the framework for the planning and control of public expenditure in the UK which has been operated since the 1998 Comprehensive Spending Review (CSR). It sets out the different classifications of spending for budgeting purposes and why these distinctions have been adopted. It discusses how the public expenditure framework is designed to ensure both sound public finances and an outcome-focused approach to public expenditure.The UK's public spending framework is based on several key principles:"consistency with a long-term, prudent and transparent regime for managing the public finances as a whole;" "the judgement of success by policy outcomes rather than resource inputs;" "strong incentives for departments and their partners in service delivery to plan over several years and plan together where appropriate so as to deliver better public services with greater cost effectiveness; and"the proper costing and management of capital assets to provide the right incentives for public investment.The Government sets policy to meet two firm fiscal rules:"the Golden Rule states that over the economic cycle, the Government will borrow only to invest and not to fund current spending; and"the Sustainable Investment Rule states that net public debt as a proportion of GDP will be held over the economic cycle at a stable and prudent level. Other things being equal, net debt will be maintained below 40 per cent of GDP over the economic cycle.Achievement of the fiscal rules is assessed by reference to the national accounts, which are produced by the Office for National Statistics, acting as an independent agency. The Government sets its spending envelope to comply with these fiscal rules.Departmental Expenditure Limits ( DEL) and Annually Managed Expenditure (AME)"Departmental Expenditure Limit ( DEL) spending, which is planned and controlled on a three year basis in Spending Reviews; and"Annually Managed Expenditure ( AME), which is expenditure which cannot reasonably be subject to firm, multi-year limits in the same way as DEL. AME includes social security benefits, local authority self-financed expenditure, debt interest, and payments to EU institutions.More information about DEL and AME is set out below.In Spending Reviews, firm DEL plans are set for departments for three years. To ensure consistency with the Government's fiscal rules departments are set separate resource (current) and capital budgets. The resource budget contains a separate control total for “near cash” expenditure, that is expenditure such as pay and current grants which impacts directly on the measure of the golden rule.To encourage departments to plan over the medium term departments may carry forward unspent DEL provision from one year into the next and, subject to the normal tests for tautness and realism of plans, may be drawn down in future years. This end-year flexibility also removes any incentive for departments to use up their provision as the year end approaches with less regard to value for money. For the full benefits of this flexibility and of three year plans to feed through into improved public service delivery, end-year flexibility and three year budgets should be cascaded from departments to executive agencies and other budget holders.Three year budgets and end-year flexibility give those managing public services the stability to plan their operations on a sensible time scale. Further, the system means that departments cannot seek to bid up funds each year (before 1997, three year plans were set and reviewed in annual Public Expenditure Surveys). So the credibility of medium-term plans has been enhanced at both central and departmental level.Departments have certainty over the budgetary allocation over the medium term and these multi-year DEL plans are strictly enforced. Departments are expected to prioritise competing pressures and fund these within their overall annual limits, as set in Spending Reviews. So the DEL system provides a strong incentive to control costs and maximise value for money.There is a small centrally held DEL Reserve. Support from the Reserve is available only for genuinely unforeseeable contingencies which departments cannot be expected to manage within their DEL.AME typically consists of programmes which are large, volatile and demand-led, and which therefore cannot reasonably be subject to firm multi-year limits. The biggest single element is social security spending. Other items include tax credits, Local Authority Self Financed Expenditure, Scottish Executive spending financed by non-domestic rates, and spending financed from the proceeds of the National Lottery.AME is reviewed twice a year as part of the Budget and Pre-Budget Report process reflecting the close integration of the tax and benefit system, which was enhanced by the introduction of tax credits.AME is not subject to the same three year expenditure limits as DEL, but is still part of the overall envelope for public expenditure. Affordability is taken into account when policy decisions affecting AME are made. The Government has committed itself not to take policy measures which are likely to have the effect of increasing social security or other elements of AME without taking steps to ensure that the effects of those decisions can be accommodated prudently within the Government's fiscal rules.Given an overall envelope for public spending, forecasts of AME affect the level of resources available for DEL spending. Cautious estimates and the AME margin are built in to these AME forecasts and reduce the risk of overspending on AME.Together, DEL plus AME sum to Total Managed Expenditure (TME). TME is a measure drawn from national accounts. It represents the current and capital spending of the public sector. The public sector is made up of central government, local government and public corporations.Resource and Capital Budgets are set in terms of accruals information. Accruals information measures resources as they are consumed rather than when the cash is paid. So for example the Resource Budget includes a charge for depreciation, a measure of the consumption or wearing out of capital assets."Non cash charges in budgets do not impact directly on the fiscal framework. That may be because the national accounts use a different way of measuring the same thing, for example in the case of the depreciation of departmental assets. Or it may be that the national accounts measure something different: for example, resource budgets include a cost of capital charge reflecting the opportunity cost of holding capital; the national accounts include debt interest."Within the Resource Budget DEL, departments have separate controls on:"Near cash spending, the sub set of Resource Budgets which impacts directly on the Golden Rule; and"The amount of their Resource Budget DEL that departments may spend on running themselves (e.g. paying most civil servants’ salaries) is limited by Administration Budgets, which are set in Spending Reviews. Administration Budgets are used to ensure that as much money as practicable is available for front line services and programmes. These budgets also help to drive efficiency improvements in departments’ own activities. Administration Budgets exclude the costs of frontline services delivered directly by departments.The Budget preceding a Spending Review sets an overall envelope for public spending that is consistent with the fiscal rules for the period covered by the Spending Review. In the Spending Review, the Budget AME forecast for year one of the Spending Review period is updated, and AME forecasts are made for the later years of the Spending Review period.The 1998 Comprehensive Spending Review ( CSR), which was published in July 1998, was a comprehensive review of departmental aims and objectives alongside a zero-based analysis of each spending programme to determine the best way of delivering the Government's objectives. The 1998 CSR allocated substantial additional resources to the Government's key priorities, particularly education and health, for the three year period from 1999-2000 to 2001-02.Delivering better public services does not just depend on how much money the Government spends, but also on how well it spends it. Therefore the 1998 CSR introduced Public Service Agreements (PSAs). Each major government department was given its own PSA setting out clear targets for achievements in terms of public service improvements.The 1998 CSR also introduced the DEL/ AME framework for the control of public spending, and made other framework changes. Building on the investment and reforms delivered by the 1998 CSR, successive spending reviews in 2000, 2002 and 2004 have:"provided significant increase in resources for the Government’s priorities, in particular health and education, and cross-cutting themes such as raising productivity; extending opportunity; and building strong and secure communities;" "enabled the Government significantly to increase investment in public assets and address the legacy of under investment from past decades. Departmental Investment Strategies were introduced in SR2000. As a result there has been a steady increase in public sector net investment from less than ¾ of a per cent of GDP in 1997-98 to 2¼ per cent of GDP in 2005-06, providing better infrastructure across public services;" "introduced further refinements to the performance management framework. PSA targets have been reduced in number over successive spending reviews from around 300 to 110 to give greater focus to the Government’s highest priorities. The targets have become increasingly outcome-focused to deliver further improvements in key areas of public service delivery across Government. They have also been refined in line with the conclusions of the Devolving Decision Making Review to provide a framework which encourages greater devolution and local flexibility. Technical Notes were introduced in SR2000 explaining how performance against each PSA target will be measured; and"not only allocated near cash spending to departments, but also – since SR2002 - set Resource DEL plans for non cash spending.To identify what further investments and reforms are needed to equip the UK for the global challenges of the decade ahead, on 19 July 2005 the Chief Secretary to the Treasury announced that the Government intends to launch a second Comprehensive Spending Review (CSR) reporting in 2007.A decade on from the first CSR, the 2007 CSR will represent a long-term and fundamental review of government expenditure. It will cover departmental allocations for 2008-09, 2009-10 and 2010 11. Allocations for 2007-08 will be held to the agreed figures already announced by the 2004 Spending Review. To provide a rigorous analytical framework for these departmental allocations, the Government will be taking forward a programme of preparatory work over 2006 involving:"an assessment of what the sustained increases in spending and reforms to public service delivery have achieved since the first CSR. The assessment will inform the setting of new objectives for the decade ahead;" "an examination of the key long-term trends and challenges that will shape the next decade – including demographic and socio-economic change, globalisation, climate and environmental change, global insecurity and technological change – together with an assessment of how public services will need to respond;" "to release the resources needed to address these challenges, and to continue to secure maximum value for money from public spending over the CSR period, a set of zero-based reviews of departments’ baseline expenditure to assess its effectiveness in delivering the Government’s long-term objectives; together with"further development of the efficiency programme, building on the cross cutting areas identified in the Gershon Review, to embed and extend ongoing efficiency savings into departmental expenditure planning.The 2007 CSR also offers the opportunity to continue to refine the PSA framework so that it drives effective delivery and the attainment of ambitious national standards.Public Service Agreements (PSAs) were introduced in the 1998 CSR. They set out agreed targets detailing the outputs and outcomes departments are expected to deliver with the resources allocated to them. The new spending regime places a strong emphasis on outcome targets, for example in providing for better health and higher educational standards or service standards. The introduction in SR2004 of PSA ‘standards’ will ensure that high standards in priority areas are maintained.The Government monitors progress against PSA targets, and departments report in detail twice a year in their annual Departmental Reports (published in spring) and in their autumn performance reports. These reports provide Parliament and the public with regular updates on departments’ performance against their targets.Technical Notes explain how performance against each PSA target will be measured.To make the most of both new investment and existing assets, there needs to be a coherent long term strategy against which investment decisions are taken. Departmental Investment Strategies (DIS) set out each department's plans to deliver the scale and quality of capital stock needed to underpin its objectives. The DIS includes information about the department's existing capital stock and future plans for that stock, as well as plans for new investment. It also sets out the systems that the department has in place to ensure that it delivers its capital programmes effectively.This document was updated on 19 December 2005.Near-cash resource expenditure that has a related cash implication, even though the timing of the cash payment may be slightly different. For example, expenditure on gas or electricity supply is incurred as the fuel is used, though the cash payment might be made in arrears on aquarterly basis. Other examples of near-cash expenditure are: pay, rental.Net cash requirement the upper limit agreed by Parliament on the cash which a department may draw from theConsolidated Fund to finance the expenditure within the ambit of its Request forResources. It is equal to the agreed amount of net resources and net capital less non-cashitems and working capital.Non-cash cost costs where there is no cash transaction but which are included in a body’s accounts (or taken into account in charging for a service) to establish the true cost of all the resourcesused.Non-departmental a body which has a role in the processes of government, but is not a government public body, NDPBdepartment or part of one.

Before Romans described western Iberia or Hispania as "Lusitania," ancient Iberians inhabited the land. Phoenician and Greek trading settlements grew up in the Tagus estuary area and nearby coasts. Beginning around 202 BCE, Romans invaded what is today southern Portugal. With Rome's defeat of Carthage, Romans proceeded to conquer and rule the western region north of the Tagus, which they named Roman "Lusitania." In the fourth century CE, as Rome's rule weakened, the area experienced yet another invasion—Germanic tribes, principally the Suevi, who eventually were Christianized. During the sixth century CE, the Suevi kingdom was superseded by yet another Germanic tribe—the Christian Visigoths.A major turning point in Portugal's history came in 711, as Muslim armies from North Africa, consisting of both Arab and Berber elements, invaded the Iberian Peninsula from across the Straits of Gibraltar. They entered what is now Portugal in 714, and proceeded to conquer most of the country except for the far north. For the next half a millennium, Islam and Muslim presence in Portugal left a significant mark upon the politics, government, language, and culture of the country.Islam, Reconquest, and Portugal Created, 714-1140The long frontier struggle between Muslim invaders and Christian communities in the north of the Iberian peninsula was called the Reconquista (Reconquest). It was during this struggle that the first dynasty of Portuguese kings (Burgundian) emerged and the independent monarchy of Portugal was established. Christian forces moved south from what is now the extreme north of Portugal and gradually defeated Muslim forces, besieging and capturing towns under Muslim sway. In the ninth century, as Christian forces slowly made their way southward, Christian elements were dominant only in the area between Minho province and the Douro River; this region became known as "territorium Portu-calense."In the 11th century, the advance of the Reconquest quickened as local Christian armies were reinforced by crusading knights from what is now France and England. Christian forces took Montemor (1034), at the Mondego River; Lamego (1058); Viseu (1058); and Coimbra (1064). In 1095, the king of Castile and Léon granted the country of "Portu-cale," what became northern Portugal, to a Burgundian count who had emigrated from France. This was the foundation of Portugal. In 1139, a descendant of this count, Afonso Henriques, proclaimed himself "King of Portugal." He was Portugal's first monarch, the "Founder," and the first of the Burgundian dynasty, which ruled until 1385.The emergence of Portugal in the 12th century as a separate monarchy in Iberia occurred before the Christian Reconquest of the peninsula. In the 1140s, the pope in Rome recognized Afonso Henriques as king of Portugal. In 1147, after a long, bloody siege, Muslim-occupied Lisbon fell to Afonso Henriques's army. Lisbon was the greatest prize of the 500-year war. Assisting this effort were English crusaders on their way to the Holy Land; the first bishop of Lisbon was an Englishman. When the Portuguese captured Faro and Silves in the Algarve province in 1248-50, the Reconquest of the extreme western portion of the Iberian peninsula was complete—significantly, more than two centuries before the Spanish crown completed the Reconquest of the eastern portion by capturing Granada in 1492.Consolidation and Independence of Burgundian Portugal, 1140-1385Two main themes of Portugal's early existence as a monarchy are the consolidation of control over the realm and the defeat of a Castil-ian threat from the east to its independence. At the end of this period came the birth of a new royal dynasty (Aviz), which prepared to carry the Christian Reconquest beyond continental Portugal across the straits of Gibraltar to North Africa. There was a variety of motives behind these developments. Portugal's independent existence was imperiled by threats from neighboring Iberian kingdoms to the north and east. Politics were dominated not only by efforts against the Muslims inPortugal (until 1250) and in nearby southern Spain (until 1492), but also by internecine warfare among the kingdoms of Castile, Léon, Aragon, and Portugal. A final comeback of Muslim forces was defeated at the battle of Salado (1340) by allied Castilian and Portuguese forces. In the emerging Kingdom of Portugal, the monarch gradually gained power over and neutralized the nobility and the Church.The historic and commonplace Portuguese saying "From Spain, neither a good wind nor a good marriage" was literally played out in diplomacy and war in the late 14th-century struggles for mastery in the peninsula. Larger, more populous Castile was pitted against smaller Portugal. Castile's Juan I intended to force a union between Castile and Portugal during this era of confusion and conflict. In late 1383, Portugal's King Fernando, the last king of the Burgundian dynasty, suddenly died prematurely at age 38, and the Master of Aviz, Portugal's most powerful nobleman, took up the cause of independence and resistance against Castile's invasion. The Master of Aviz, who became King João I of Portugal, was able to obtain foreign assistance. With the aid of English archers, Joao's armies defeated the Castilians in the crucial battle of Aljubarrota, on 14 August 1385, a victory that assured the independence of the Portuguese monarchy from its Castilian nemesis for several centuries.Aviz Dynasty and Portugal's First Overseas Empire, 1385-1580The results of the victory at Aljubarrota, much celebrated in Portugal's art and monuments, and the rise of the Aviz dynasty also helped to establish a new merchant class in Lisbon and Oporto, Portugal's second city. This group supported King João I's program of carrying the Reconquest to North Africa, since it was interested in expanding Portugal's foreign commerce and tapping into Muslim trade routes and resources in Africa. With the Reconquest against the Muslims completed in Portugal and the threat from Castile thwarted for the moment, the Aviz dynasty launched an era of overseas conquest, exploration, and trade. These efforts dominated Portugal's 15th and 16th centuries.The overseas empire and age of Discoveries began with Portugal's bold conquest in 1415 of the Moroccan city of Ceuta. One royal member of the 1415 expedition was young, 21-year-old Prince Henry, later known in history as "Prince Henry the Navigator." His part in the capture of Ceuta won Henry his knighthood and began Portugal's "Marvelous Century," during which the small kingdom was counted as a European and world power of consequence. Henry was the son of King João I and his English queen, Philippa of Lancaster, but he did not inherit the throne. Instead, he spent most of his life and his fortune, and that of the wealthy military Order of Christ, on various imperial ventures and on voyages of exploration down the African coast and into the Atlantic. While mythology has surrounded Henry's controversial role in the Discoveries, and this role has been exaggerated, there is no doubt that he played a vital part in the initiation of Portugal's first overseas empire and in encouraging exploration. He was naturally curious, had a sense of mission for Portugal, and was a strong leader. He also had wealth to expend; at least a third of the African voyages of the time were under his sponsorship. If Prince Henry himself knew little science, significant scientific advances in navigation were made in his day.What were Portugal's motives for this new imperial effort? The well-worn historical cliche of "God, Glory, and Gold" can only partly explain the motivation of a small kingdom with few natural resources and barely 1 million people, which was greatly outnumbered by the other powers it confronted. Among Portuguese objectives were the desire to exploit known North African trade routes and resources (gold, wheat, leather, weaponry, and other goods that were scarce in Iberia); the need to outflank the Muslim world in the Mediterranean by sailing around Africa, attacking Muslims en route; and the wish to ally with Christian kingdoms beyond Africa. This enterprise also involved a strategy of breaking the Venetian spice monopoly by trading directly with the East by means of discovering and exploiting a sea route around Africa to Asia. Besides the commercial motives, Portugal nurtured a strong crusading sense of Christian mission, and various classes in the kingdom saw an opportunity for fame and gain.By the time of Prince Henry's death in 1460, Portugal had gained control of the Atlantic archipelagos of the Azores and Madeiras, begun to colonize the Cape Verde Islands, failed to conquer the Canary Islands from Castile, captured various cities on Morocco's coast, and explored as far as Senegal, West Africa, down the African coast. By 1488, Bar-tolomeu Dias had rounded the Cape of Good Hope in South Africa and thereby discovered the way to the Indian Ocean.Portugal's largely coastal African empire and later its fragile Asian empire brought unexpected wealth but were purchased at a high price. Costs included wars of conquest and defense against rival powers, manning the far-flung navel and trade fleets and scattered castle-fortresses, and staffing its small but fierce armies, all of which entailed a loss of skills and population to maintain a scattered empire. Always short of capital, the monarchy became indebted to bankers. There were many defeats beginning in the 16th century at the hands of the larger imperial European monarchies (Spain, France, England, and Holland) and many attacks on Portugal and its strung-out empire. Typically, there was also the conflict that arose when a tenuously held world empire that rarely if ever paid its way demanded finance and manpower Portugal itself lacked.The first 80 years of the glorious imperial era, the golden age of Portugal's imperial power and world influence, was an African phase. During 1415-88, Portuguese navigators and explorers in small ships, some of them caravelas (caravels), explored the treacherous, disease-ridden coasts of Africa from Morocco to South Africa beyond the Cape of Good Hope. By the 1470s, the Portuguese had reached the Gulf of Guinea and, in the early 1480s, what is now Angola. Bartolomeu Dias's extraordinary voyage of 1487-88 to South Africa's coast and the edge of the Indian Ocean convinced Portugal that the best route to Asia's spices and Christians lay south, around the tip of southern Africa. Between 1488 and 1495, there was a hiatus caused in part by domestic conflict in Portugal, discussion of resources available for further conquests beyond Africa in Asia, and serious questions as to Portugal's capacity to reach beyond Africa. In 1495, King Manuel and his council decided to strike for Asia, whatever the consequences. In 1497-99, Vasco da Gama, under royal orders, made the epic two-year voyage that discovered the sea route to western India (Asia), outflanked Islam and Venice, and began Portugal's Asian empire. Within 50 years, Portugal had discovered and begun the exploitation of its largest colony, Brazil, and set up forts and trading posts from the Middle East (Aden and Ormuz), India (Calicut, Goa, etc.), Malacca, and Indonesia to Macau in China.By the 1550s, parts of its largely coastal, maritime trading post empire from Morocco to the Moluccas were under siege from various hostile forces, including Muslims, Christians, and Hindi. Although Moroccan forces expelled the Portuguese from the major coastal cities by 1550, the rival European monarchies of Castile (Spain), England, France, and later Holland began to seize portions of her undermanned, outgunned maritime empire.In 1580, Phillip II of Spain, whose mother was a Portuguese princess and who had a strong claim to the Portuguese throne, invaded Portugal, claimed the throne, and assumed control over the realm and, by extension, its African, Asian, and American empires. Phillip II filled the power vacuum that appeared in Portugal following the loss of most of Portugal's army and its young, headstrong King Sebastião in a disastrous war in Morocco. Sebastiao's death in battle (1578) and the lack of a natural heir to succeed him, as well as the weak leadership of the cardinal who briefly assumed control in Lisbon, led to a crisis that Spain's strong monarch exploited. As a result, Portugal lost its independence to Spain for a period of 60 years.Portugal under Spanish Rule, 1580-1640Despite the disastrous nature of Portugal's experience under Spanish rule, "The Babylonian Captivity" gave birth to modern Portuguese nationalism, its second overseas empire, and its modern alliance system with England. Although Spain allowed Portugal's weakened empire some autonomy, Spanish rule in Portugal became increasingly burdensome and unacceptable. Spain's ambitious imperial efforts in Europe and overseas had an impact on the Portuguese as Spain made greater and greater demands on its smaller neighbor for manpower and money. Portugal's culture underwent a controversial Castilianization, while its empire became hostage to Spain's fortunes. New rival powers England, France, and Holland attacked and took parts of Spain's empire and at the same time attacked Portugal's empire, as well as the mother country.Portugal's empire bore the consequences of being attacked by Spain's bitter enemies in what was a form of world war. Portuguese losses were heavy. By 1640, Portugal had lost most of its Moroccan cities as well as Ceylon, the Moluccas, and sections of India. With this, Portugal's Asian empire was gravely weakened. Only Goa, Damão, Diu, Bombay, Timor, and Macau remained and, in Brazil, Dutch forces occupied the northeast.On 1 December 1640, long commemorated as a national holiday, Portuguese rebels led by the duke of Braganza overthrew Spanish domination and took advantage of Spanish weakness following a more serious rebellion in Catalonia. Portugal regained independence from Spain, but at a price: dependence on foreign assistance to maintain its independence in the form of the renewal of the alliance with England.Restoration and Second Empire, 1640-1822Foreign affairs and empire dominated the restoration era and aftermath, and Portugal again briefly enjoyed greater European power and prestige. The Anglo-Portuguese Alliance was renewed and strengthened in treaties of 1642, 1654, and 1661, and Portugal's independence from Spain was underwritten by English pledges and armed assistance. In a Luso-Spanish treaty of 1668, Spain recognized Portugal's independence. Portugal's alliance with England was a marriage of convenience and necessity between two monarchies with important religious, cultural, and social differences. In return for legal, diplomatic, and trade privileges, as well as the use during war and peace of Portugal's great Lisbon harbor and colonial ports for England's navy, England pledged to protect Portugal and its scattered empire from any attack. The previously cited 17th-century alliance treaties were renewed later in the Treaty of Windsor, signed in London in 1899. On at least 10 different occasions after 1640, and during the next two centuries, England was central in helping prevent or repel foreign invasions of its ally, Portugal.Portugal's second empire (1640-1822) was largely Brazil-oriented. Portuguese colonization, exploitation of wealth, and emigration focused on Portuguese America, and imperial revenues came chiefly from Brazil. Between 1670 and 1740, Portugal's royalty and nobility grew wealthier on funds derived from Brazilian gold, diamonds, sugar, tobacco, and other crops, an enterprise supported by the Atlantic slave trade and the supply of African slave labor from West Africa and Angola. Visitors today can see where much of that wealth was invested: Portugal's rich legacy of monumental architecture. Meanwhile, the African slave trade took a toll in Angola and West Africa.In continental Portugal, absolutist monarchy dominated politics and government, and there was a struggle for position and power between the monarchy and other institutions, such as the Church and nobility. King José I's chief minister, usually known in history as the marquis of Pombal (ruled 1750-77), sharply suppressed the nobility and theChurch (including the Inquisition, now a weak institution) and expelled the Jesuits. Pombal also made an effort to reduce economic dependence on England, Portugal's oldest ally. But his successes did not last much beyond his disputed time in office.Beginning in the late 18th century, the European-wide impact of the French Revolution and the rise of Napoleon placed Portugal in a vulnerable position. With the monarchy ineffectively led by an insane queen (Maria I) and her indecisive regent son (João VI), Portugal again became the focus of foreign ambition and aggression. With England unable to provide decisive assistance in time, France—with Spain's consent—invaded Portugal in 1807. As Napoleon's army under General Junot entered Lisbon meeting no resistance, Portugal's royal family fled on a British fleet to Brazil, where it remained in exile until 1821. In the meantime, Portugal's overseas empire was again under threat. There was a power vacuum as the monarch was absent, foreign armies were present, and new political notions of liberalism and constitutional monarchy were exciting various groups of citizens.Again England came to the rescue, this time in the form of the armies of the duke of Wellington. Three successive French invasions of Portugal were defeated and expelled, and Wellington succeeded in carrying the war against Napoleon across the Portuguese frontier into Spain. The presence of the English army, the new French-born liberal ideas, and the political vacuum combined to create revolutionary conditions. The French invasions and the peninsular wars, where Portuguese armed forces played a key role, marked the beginning of a new era in politics.Liberalism and Constitutional Monarchy, 1822-1910During 1807-22, foreign invasions, war, and civil strife over conflicting political ideas gravely damaged Portugal's commerce, economy, and novice industry. The next terrible blow was the loss of Brazil in 1822, the jewel in the imperial crown. Portugal's very independence seemed to be at risk. In vain, Portugal sought to resist Brazilian independence by force, but in 1825 it formally acknowledged Brazilian independence by treaty.Portugal's slow recovery from the destructive French invasions and the "war of independence" was complicated by civil strife over the form of constitutional monarchy that best suited Portugal. After struggles over these issues between 1820 and 1834, Portugal settled somewhat uncertainly into a moderate constitutional monarchy whose constitution (Charter of 1826) lent it strong political powers to exert a moderating influence between the executive and legislative branches of the government. It also featured a new upper middle class based on land ownership and commerce; a Catholic Church that, although still important, lived with reduced privileges and property; a largely African (third) empire to which Lisbon and Oporto devoted increasing spiritual and material resources, starting with the liberal imperial plans of 1836 and 1851, and continuing with the work of institutions like the Lisbon Society of Geography (established 1875); and a mass of rural peasants whose bonds to the land weakened after 1850 and who began to immigrate in increasing numbers to Brazil and North America.Chronic military intervention in national politics began in 19th-century Portugal. Such intervention, usually commencing with coups or pronunciamentos (military revolts), was a shortcut to the spoils of political office and could reflect popular discontent as well as the power of personalities. An early example of this was the 1817 golpe (coup) attempt of General Gomes Freire against British military rule in Portugal before the return of King João VI from Brazil. Except for a more stable period from 1851 to 1880, military intervention in politics, or the threat thereof, became a feature of the constitutional monarchy's political life, and it continued into the First Republic and the subsequent Estado Novo.Beginning with the Regeneration period (1851-80), Portugal experienced greater political stability and economic progress. Military intervention in politics virtually ceased; industrialization and construction of railroads, roads, and bridges proceeded; two political parties (Regenerators and Historicals) worked out a system of rotation in power; and leading intellectuals sparked a cultural revival in several fields. In 19th-century literature, there was a new golden age led by such figures as Alexandre Herculano (historian), Eça de Queirós (novelist), Almeida Garrett (playwright and essayist), Antero de Quental (poet), and Joaquim Oliveira Martins (historian and social scientist). In its third overseas empire, Portugal attempted to replace the slave trade and slavery with legitimate economic activities; to reform the administration; and to expand Portuguese holdings beyond coastal footholds deep into the African hinterlands in West, West Central, and East Africa. After 1841, to some extent, and especially after 1870, colonial affairs, combined with intense nationalism, pressures for economic profit in Africa, sentiment for national revival, and the drift of European affairs would make or break Lisbon governments.Beginning with the political crisis that arose out of the "English Ultimatum" affair of January 1890, the monarchy became discredtted and identified with the poorly functioning government, political parties splintered, and republicanism found more supporters. Portugal participated in the "Scramble for Africa," expanding its African holdings, but failed to annex territory connecting Angola and Mozambique. A growing foreign debt and state bankruptcy as of the early 1890s damaged the constitutional monarchy's reputation, despite the efforts of King Carlos in diplomacy, the renewal of the alliance in the Windsor Treaty of 1899, and the successful if bloody colonial wars in the empire (1880-97). Republicanism proclaimed that Portugal's weak economy and poor society were due to two historic institutions: the monarchy and the Catholic Church. A republic, its stalwarts claimed, would bring greater individual liberty; efficient, if more decentralized government; and a stronger colonial program while stripping the Church of its role in both society and education.As the monarchy lost support and republicans became more aggressive, violence increased in politics. King Carlos I and his heir Luís were murdered in Lisbon by anarchist-republicans on 1 February 1908. Following a military and civil insurrection and fighting between monarchist and republican forces, on 5 October 1910, King Manuel II fled Portugal and a republic was proclaimed.First Parliamentary Republic, 1910-26Portugal's first attempt at republican government was the most unstable, turbulent parliamentary republic in the history of 20th-century Western Europe. During a little under 16 years of the republic, there were 45 governments, a number of legislatures that did not complete normal terms, military coups, and only one president who completed his four-year term in office. Portuguese society was poorly prepared for this political experiment. Among the deadly legacies of the monarchy were a huge public debt; a largely rural, apolitical, and illiterate peasant population; conflict over the causes of the country's misfortunes; and lack of experience with a pluralist, democratic system.The republic had some talented leadership but lacked popular, institutional, and economic support. The 1911 republican constitution established only a limited democracy, as only a small portion of the adult male citizenry was eligible to vote. In a country where the majority was Catholic, the republic passed harshly anticlerical laws, and its institutions and supporters persecuted both the Church and its adherents. During its brief disjointed life, the First Republic drafted important reform plans in economic, social, and educational affairs; actively promoted development in the empire; and pursued a liberal, generous foreign policy. Following British requests for Portugal's assistance in World War I, Portugal entered the war on the Allied side in March 1916 and sent armies to Flanders and Portuguese Africa. Portugal's intervention in that conflict, however, was too costly in many respects, and the ultimate failure of the republic in part may be ascribed to Portugal's World War I activities.Unfortunately for the republic, its time coincided with new threats to Portugal's African possessions: World War I, social and political demands from various classes that could not be reconciled, excessive military intervention in politics, and, in particular, the worst economic and financial crisis Portugal had experienced since the 16th and 17th centuries. After the original Portuguese Republican Party (PRP, also known as the "Democrats") splintered into three warring groups in 1912, no true multiparty system emerged. The Democrats, except for only one or two elections, held an iron monopoly of electoral power, and political corruption became a major issue. As extreme right-wing dictatorships elsewhere in Europe began to take power in Italy (1922), neighboring Spain (1923), and Greece (1925), what scant popular support remained for the republic collapsed. Backed by a right-wing coalition of landowners from Alentejo, clergy, Coimbra University faculty and students, Catholic organizations, and big business, career military officers led by General Gomes da Costa executed a coup on 28 May 1926, turned out the last republican government, and established a military government.The Estado Novo (New State), 1926-74During the military phase (1926-32) of the Estado Novo, professional military officers, largely from the army, governed and administered Portugal and held key cabinet posts, but soon discovered that the military possessed no magic formula that could readily solve the problems inherited from the First Republic. Especially during the years 1926-31, the military dictatorship, even with its political repression of republican activities and institutions (military censorship of the press, political police action, and closure of the republic's rowdy parliament), was characterized by similar weaknesses: personalism and factionalism; military coups and political instability, including civil strife and loss of life; state debt and bankruptcy; and a weak economy. "Barracks parliamentarism" was not an acceptable alternative even to the "Nightmare Republic."Led by General Óscar Carmona, who had replaced and sent into exile General Gomes da Costa, the military dictatorship turned to a civilian expert in finance and economics to break the budget impasse and bring coherence to the disorganized system. Appointed minister of finance on 27 April 1928, the Coimbra University Law School professor of economics Antônio de Oliveira Salazar (1889-1970) first reformed finance, helped balance the budget, and then turned to other concerns as he garnered extraordinary governing powers. In 1930, he was appointed interim head of another key ministry (Colonies) and within a few years had become, in effect, a civilian dictator who, with the military hierarchy's support, provided the government with coherence, a program, and a set of policies.For nearly 40 years after he was appointed the first civilian prime minister in 1932, Salazar's personality dominated the government. Unlike extreme right-wing dictators elsewhere in Europe, Salazar was directly appointed by the army but was never endorsed by a popular political party, street militia, or voter base. The scholarly, reclusive former Coimbra University professor built up what became known after 1932 as the Estado Novo ("New State"), which at the time of its overthrow by another military coup in 1974, was the longest surviving authoritarian regime in Western Europe. The system of Salazar and the largely academic and technocratic ruling group he gathered in his cabinets was based on the central bureaucracy of the state, which was supported by the president of the republic—always a senior career military officer, General Óscar Carmona (1928-51), General Craveiro Lopes (1951-58), and Admiral Américo Tómaz (1958-74)—and the complicity of various institutions. These included a rubber-stamp legislature called the National Assembly (1935-74) and a political police known under various names: PVDE (1932-45), PIDE (1945-69),and DGS (1969-74). Other defenders of the Estado Novo security were paramilitary organizations such as the National Republican Guard (GNR); the Portuguese Legion (PL); and the Portuguese Youth [Movement]. In addition to censorship of the media, theater, and books, there was political repression and a deliberate policy of depoliticization. All political parties except for the approved movement of regime loyalists, the União Nacional or (National Union), were banned.The most vigorous and more popular period of the New State was 1932-44, when the basic structures were established. Never monolithic or entirely the work of one person (Salazar), the New State was constructed with the assistance of several dozen top associates who were mainly academics from law schools, some technocrats with specialized skills, and a handful of trusted career military officers. The 1933 Constitution declared Portugal to be a "unitary, corporative Republic," and pressures to restore the monarchy were resisted. Although some of the regime's followers were fascists and pseudofascists, many more were conservative Catholics, integralists, nationalists, and monarchists of different varieties, and even some reactionary republicans. If the New State was authoritarian, it was not totalitarian and, unlike fascism in Benito Mussolini's Italy or Adolf Hitler's Germany, it usually employed the minimum of violence necessary to defeat what remained a largely fractious, incoherent opposition.With the tumultuous Second Republic and the subsequent civil war in nearby Spain, the regime felt threatened and reinforced its defenses. During what Salazar rightly perceived as a time of foreign policy crisis for Portugal (1936-45), he assumed control of the Ministry of Foreign Affairs. From there, he pursued four basic foreign policy objectives: supporting the Nationalist rebels of General Francisco Franco in the Spanish Civil War (1936-39) and concluding defense treaties with a triumphant Franco; ensuring that General Franco in an exhausted Spain did not enter World War II on the Axis side; maintaining Portuguese neutrality in World War II with a post-1942 tilt toward the Allies, including granting Britain and the United States use of bases in the Azores Islands; and preserving and protecting Portugal's Atlantic Islands and its extensive, if poor, overseas empire in Africa and Asia.During the middle years of the New State (1944-58), many key Salazar associates in government either died or resigned, and there was greater social unrest in the form of unprecedented strikes and clandestine Communist activities, intensified opposition, and new threatening international pressures on Portugal's overseas empire. During the earlier phase of the Cold War (1947-60), Portugal became a steadfast, if weak, member of the US-dominated North Atlantic Treaty Organization alliance and, in 1955, with American support, Portugal joined the United Nations (UN). Colonial affairs remained a central concern of the regime. As of 1939, Portugal was the third largest colonial power in the world and possessed territories in tropical Africa (Angola, Mozambique, Guinea-Bissau, and São Tomé and Príncipe Islands) and the remnants of its 16th-century empire in Asia (Goa, Damão, Diu, East Timor, and Macau). Beginning in the early 1950s, following the independence of India in 1947, Portugal resisted Indian pressures to decolonize Portuguese India and used police forces to discourage internal opposition in its Asian and African colonies.The later years of the New State (1958-68) witnessed the aging of the increasingly isolated but feared Salazar and new threats both at home and overseas. Although the regime easily overcame the brief oppositionist threat from rival presidential candidate General Humberto Delgado in the spring of 1958, new developments in the African and Asian empires imperiled the authoritarian system. In February 1961, oppositionists hijacked the Portuguese ocean liner Santa Maria and, in following weeks, African insurgents in northern Angola, although they failed to expel the Portuguese, gained worldwide media attention, discredited the New State, and began the 13-year colonial war. After thwarting a dissident military coup against his continued leadership, Salazar and his ruling group mobilized military repression in Angola and attempted to develop the African colonies at a faster pace in order to ensure Portuguese control. Meanwhile, the other European colonial powers (Britain, France, Belgium, and Spain) rapidly granted political independence to their African territories.At the time of Salazar's removal from power in September 1968, following a stroke, Portugal's efforts to maintain control over its colonies appeared to be successful. President Americo Tomás appointed Dr. Marcello Caetano as Salazar's successor as prime minister. While maintaining the New State's basic structures, and continuing the regime's essential colonial policy, Caetano attempted wider reforms in colonial administration and some devolution of power from Lisbon, as well as more freedom of expression in Lisbon. Still, a great deal of the budget was devoted to supporting the wars against the insurgencies in Africa. Meanwhile in Asia, Portuguese India had fallen when the Indian army invaded in December 1961. The loss of Goa was a psychological blow to the leadership of the New State, and of the Asian empire only East Timor and Macau remained.The Caetano years (1968-74) were but a hiatus between the waning Salazar era and a new regime. There was greater political freedom and rapid economic growth (5-6 percent annually to late 1973), but Caetano's government was unable to reform the old system thoroughly and refused to consider new methods either at home or in the empire. In the end, regime change came from junior officers of the professional military who organized the Armed Forces Movement (MFA) against the Caetano government. It was this group of several hundred officers, mainly in the army and navy, which engineered a largely bloodless coup in Lisbon on 25 April 1974. Their unexpected action brought down the 48-year-old New State and made possible the eventual establishment and consolidation of democratic governance in Portugal, as well as a reorientation of the country away from the Atlantic toward Europe.Revolution of Carnations, 1974-76Following successful military operations of the Armed Forces Movement against the Caetano government, Portugal experienced what became known as the "Revolution of Carnations." It so happened that during the rainy week of the military golpe, Lisbon flower shops were featuring carnations, and the revolutionaries and their supporters adopted the red carnation as the common symbol of the event, as well as of the new freedom from dictatorship. The MFA, whose leaders at first were mostly little-known majors and captains, proclaimed a three-fold program of change for the new Portugal: democracy; decolonization of the overseas empire, after ending the colonial wars; and developing a backward economy in the spirit of opportunity and equality. During the first 24 months after the coup, there was civil strife, some anarchy, and a power struggle. With the passing of the Estado Novo, public euphoria burst forth as the new provisional military government proclaimed the freedoms of speech, press, and assembly, and abolished censorship, the political police, the Portuguese Legion, Portuguese Youth, and other New State organizations, including the National Union. Scores of political parties were born and joined the senior political party, the Portuguese Community Party (PCP), and the Socialist Party (PS), founded shortly before the coup.Portugal's Revolution of Carnations went through several phases. There was an attempt to take control by radical leftists, including the PCP and its allies. This was thwarted by moderate officers in the army, as well as by the efforts of two political parties: the PS and the Social Democrats (PPD, later PSD). The first phase was from April to September 1974. Provisional president General Antonio Spínola, whose 1974 book Portugal and the Future had helped prepare public opinion for the coup, met irresistible leftist pressures. After Spinola's efforts to avoid rapid decolonization of the African empire failed, he resigned in September 1974. During the second phase, from September 1974 to March 1975, radical military officers gained control, but a coup attempt by General Spínola and his supporters in Lisbon in March 1975 failed and Spínola fled to Spain.In the third phase of the Revolution, March-November 1975, a strong leftist reaction followed. Farm workers occupied and "nationalized" 1.1 million hectares of farmland in the Alentejo province, and radical military officers in the provisional government ordered the nationalization of Portuguese banks (foreign banks were exempted), utilities, and major industries, or about 60 percent of the economic system. There were power struggles among various political parties — a total of 50 emerged—and in the streets there was civil strife among labor, military, and law enforcement groups. A constituent assembly, elected on 25 April 1975, in Portugal's first free elections since 1926, drafted a democratic constitution. The Council of the Revolution (CR), briefly a revolutionary military watchdog committee, was entrenched as part of the government under the constitution, until a later revision. During the chaotic year of 1975, about 30 persons were killed in political frays while unstable provisional governments came and went. On 25 November 1975, moderate military forces led by Colonel Ramalho Eanes, who later was twice elected president of the republic (1976 and 1981), defeated radical, leftist military groups' revolutionary conspiracies.In the meantime, Portugal's scattered overseas empire experienced a precipitous and unprepared decolonization. One by one, the former colonies were granted and accepted independence—Guinea-Bissau (September 1974), Cape Verde Islands (July 1975), and Mozambique (July 1975). Portugal offered to turn over Macau to the People's Republic of China, but the offer was refused then and later negotiations led to the establishment of a formal decolonization or hand-over date of 1999. But in two former colonies, the process of decolonization had tragic results.In Angola, decolonization negotiations were greatly complicated by the fact that there were three rival nationalist movements in a struggle for power. The January 1975 Alvor Agreement signed by Portugal and these three parties was not effectively implemented. A bloody civil war broke out in Angola in the spring of 1975 and, when Portuguese armed forces withdrew and declared that Angola was independent on 11 November 1975, the bloodshed only increased. Meanwhile, most of the white Portuguese settlers from Angola and Mozambique fled during the course of 1975. Together with African refugees, more than 600,000 of these retornados ("returned ones") went by ship and air to Portugal and thousands more to Namibia, South Africa, Brazil, Canada, and the United States.The second major decolonization disaster was in Portugal's colony of East Timor in the Indonesian archipelago. Portugal's capacity to supervise and control a peaceful transition to independence in this isolated, neglected colony was limited by the strength of giant Indonesia, distance from Lisbon, and Portugal's revolutionary disorder and inability to defend Timor. In early December 1975, before Portugal granted formal independence and as one party, FRETILIN, unilaterally declared East Timor's independence, Indonesia's armed forces invaded, conquered, and annexed East Timor. Indonesian occupation encountered East Timorese resistance, and a heavy loss of life followed. The East Timor question remained a contentious international issue in the UN, as well as in Lisbon and Jakarta, for more than 20 years following Indonesia's invasion and annexation of the former colony of Portugal. Major changes occurred, beginning in 1998, after Indonesia underwent a political revolution and allowed a referendum in East Timor to decide that territory's political future in August 1999. Most East Timorese chose independence, but Indonesian forces resisted that verdict untilUN intervention in September 1999. Following UN rule for several years, East Timor attained full independence on 20 May 2002.Consolidation of Democracy, 1976-2000After several free elections and record voter turnouts between 25 April 1975 and June 1976, civil war was averted and Portugal's second democratic republic began to stabilize. The MFA was dissolved, the military were returned to the barracks, and increasingly elected civilians took over the government of the country. The 1976 Constitution was revised several times beginning in 1982 and 1989, in order to reempha-size the principle of free enterprise in the economy while much of the large, nationalized sector was privatized. In June 1976, General Ram-alho Eanes was elected the first constitutional president of the republic (five-year term), and he appointed socialist leader Dr. Mário Soares as prime minister of the first constitutional government.From 1976 to 1985, Portugal's new system featured a weak economy and finances, labor unrest, and administrative and political instability. The difficult consolidation of democratic governance was eased in part by the strong currency and gold reserves inherited from the Estado Novo, but Lisbon seemed unable to cope with high unemployment, new debt, the complex impact of the refugees from Africa, world recession, and the agitation of political parties. Four major parties emerged from the maelstrom of 1974-75, except for the Communist Party, all newly founded. They were, from left to right, the Communists (PCP); the Socialists (PS), who managed to dominate governments and the legislature but not win a majority in the Assembly of the Republic; the Social Democrats (PSD); and the Christian Democrats (CDS). During this period, the annual growth rate was low (l-2 percent), and the nationalized sector of the economy stagnated.Enhanced economic growth, greater political stability, and more effective central government as of 1985, and especially 1987, were due to several developments. In 1977, Portugal applied for membership in the European Economic Community (EEC), now the European Union (EU) since 1993. In January 1986, with Spain, Portugal was granted membership, and economic and financial progress in the intervening years has been significantly influenced by the comparatively large investment, loans, technology, advice, and other assistance from the EEC. Low unemployment, high annual growth rates (5 percent), and moderate inflation have also been induced by the new political and administrative stability in Lisbon. Led by Prime Minister Cavaco Silva, an economist who was trained abroad, the PSD's strong organization, management, and electoral support since 1985 have assisted in encouraging economic recovery and development. In 1985, the PSD turned the PS out of office and won the general election, although they did not have an absolute majority of assembly seats. In 1986, Mário Soares was elected president of the republic, the first civilian to hold that office since the First Republic. In the elections of 1987 and 1991, however, the PSD was returned to power with clear majorities of over 50 percent of the vote.Although the PSD received 50.4 percent of the vote in the 1991 parliamentary elections and held a 42-seat majority in the Assembly of the Republic, the party began to lose public support following media revelations regarding corruption and complaints about Prime Minister Cavaco Silva's perceived arrogant leadership style. President Mário Soares voiced criticism of the PSD's seemingly untouchable majority and described a "tyranny of the majority." Economic growth slowed down. In the parliamentary elections of 1995 and the presidential election of 1996, the PSD's dominance ended for the time being. Prime Minister Antônio Guterres came to office when the PS won the October 1995 elections, and in the subsequent presidential contest, in January 1996, socialist Jorge Sampaio, the former mayor of Lisbon, was elected president of the republic, thus defeating Cavaco Silva's bid. Young and popular, Guterres moved the PS toward the center of the political spectrum. Under Guterres, the PS won the October 1999 parliamentary elections. The PS defeated the PSD but did not manage to win a clear, working majority of seats, and this made the PS dependent upon alliances with smaller parties, including the PCP.In the local elections in December 2001, the PSD's criticism of PS's heavy public spending allowed the PSD to take control of the key cities of Lisbon, Oporto, and Coimbra. Guterres resigned, and parliamentary elections were brought forward from 2004 to March 2002. The PSD won a narrow victory with 40 percent of the votes, and Jose Durão Barroso became prime minister. Having failed to win a majority of the seats in parliament forced the PSD to govern in coalition with the right-wing Popular Party (PP) led by Paulo Portas. Durão Barroso set about reducing government spending by cutting the budgets of local authorities, freezing civil service hiring, and reviving the economy by accelerating privatization of state-owned enterprises. These measures provoked a 24-hour strike by public-sector workers. Durão Barroso reacted with vows to press ahead with budget-cutting measures and imposed a wage freeze on all employees earning more than €1,000, which affected more than one-half of Portugal's work force.In June 2004, Durão Barroso was invited by Romano Prodi to succeed him as president of the European Commission. Durão Barroso accepted and resigned the prime ministership in July. Pedro Santana Lopes, the leader of the PSD, became prime minister. Already unpopular at the time of Durão Barroso's resignation, the PSD-led government became increasingly unpopular under Santana Lopes. A month-long delay in the start of the school year and confusion over his plan to cut taxes and raise public-sector salaries, eroded confidence even more. By November, Santana Lopes's government was so unpopular that President Jorge Sampaio was obliged to dissolve parliament and hold new elections, two years ahead of schedule.Parliamentary elections were held on 20 February 2005. The PS, which had promised the electorate disciplined and transparent governance, educational reform, the alleviation of poverty, and a boost in employment, won 45 percent of the vote and the majority of the seats in parliament. The leader of the PS, José Sôcrates became prime minister on 12 March 2005. In the regularly scheduled presidential elections held on 6 January 2006, the former leader of the PSD and prime minister, Aníbal Cavaco Silva, won a narrow victory and became president on 9 March 2006. With a mass protest, public teachers' strike, and street demonstrations in March 2008, Portugal's media, educational, and social systems experienced more severe pressures. With the spreading global recession beginning in September 2008, Portugal's economic and financial systems became more troubled.Owing to its geographic location on the southwestern most edge of continental Europe, Portugal has been historically in but not of Europe. Almost from the beginning of its existence in the 12th century as an independent monarchy, Portugal turned its back on Europe and oriented itself toward the Atlantic Ocean. After carving out a Christian kingdom on the western portion of the Iberian peninsula, Portuguese kings gradually built and maintained a vast seaborne global empire that became central to the way Portugal understood its individuality as a nation-state. While the creation of this empire allows Portugal to claim an unusual number of "firsts" or distinctions in world and Western history, it also retarded Portugal's economic, social, and political development. It can be reasonably argued that the Revolution of 25 April 1974 was the most decisive event in Portugal's long history because it finally ended Portugal's oceanic mission and view of itself as an imperial power. After the 1974 Revolution, Portugal turned away from its global mission and vigorously reoriented itself toward Europe. Contemporary Portugal is now both in and of Europe.The turn toward Europe began immediately after 25 April 1974. Portugal granted independence to its African colonies in 1975. It was admitted to the European Council and took the first steps toward accession to the European Economic Community (EEC) in 1976. On 28 March 1977, the Portuguese government officially applied for EEC membership. Because of Portugal's economic and social backwardness, which would require vast sums of EEC money to overcome, negotiations for membership were long and difficult. Finally, a treaty of accession was signed on 12 June 1985. Portugal officially joined the EEC (the European Union [EU] since 1993) on 1 January 1986. Since becoming a full-fledged member of the EU, Portugal has been steadily overcoming the economic and social underdevelopment caused by its imperial past and is becoming more like the rest of Europe.Membership in the EU has speeded up the structural transformation of Portugal's economy, which actually began during the Estado Novo. Investments made by the Estado Novo in Portugal's economy began to shift employment out of the agricultural sector, which, in 1950, accounted for 50 percent of Portugal's economically active population. Today, only 10 percent of the economically active population is employed in the agricultural sector (the highest among EU member states); 30 percent in the industrial sector (also the highest among EU member states); and 60 percent in the service sector (the lowest among EU member states). The economically active population numbers about 5,000,000 employed, 56 percent of whom are women. Women workers are the majority of the workforce in the agricultural and service sectors (the highest among the EU member states). The expansion of the service sector has been primarily in health care and education. Portugal has had the lowest unemployment rates among EU member states, with the overall rate never being more than 10 percent of the active population. Since joining the EU, the number of employers increased from 2.6 percent to 5.8 percent of the active population; self-employed from 16 to 19 percent; and employees from 65 to 70 percent. Twenty-six percent of the employers are women. Unemployment tends to hit younger workers in industry and transportation, women employed in domestic service, workers on short-term contracts, and poorly educated workers. Salaried workers earn only 63 percent of the EU average, and hourly workers only one-third to one-half of that earned by their EU counterparts. Despite having had the second highest growth of gross national product (GNP) per inhabitant (after Ireland) among EU member states, the above data suggest that while much has been accomplished in terms of modernizing the Portuguese economy, much remains to be done to bring Portugal's economy up to the level of the "average" EU member state.Membership in the EU has also speeded up changes in Portuguese society. Over the last 30 years, coastalization and urbanization have intensified. Fully 50 percent of Portuguese live in the coastal urban conurbations of Lisbon, Oporto, Braga, Aveiro, Coimbra, Viseu, Évora, and Faro. The Portuguese population is one of the oldest among EU member states (17.3 percent are 65 years of age or older) thanks to a considerable increase in life expectancy at birth (77.87 years for the total population, 74.6 years for men, 81.36 years for women) and one of the lowest birthrates (10.59 births/1,000) in Europe. Family size averages 2.8 persons per household, with the strict nuclear family (one or two generations) in which both parents work being typical. Common law marriages, cohabitating couples, and single-parent households are more and more common. The divorce rate has also increased. "Youth Culture" has developed. The young have their own meeting places, leisure-time activities, and nightlife (bars, clubs, and discos).All Portuguese citizens, whether they have contributed or not, have a right to an old-age pension, invalidity benefits, widowed persons' pension, as well as payments for disabilities, children, unemployment, and large families. There is a national minimum wage (€385 per month), which is low by EU standards. The rapid aging of Portugal's population has changed the ratio of contributors to pensioners to 1.7, the lowest in the EU. This has created deficits in Portugal's social security fund.The adult literacy rate is about 92 percent. Illiteracy is still found among the elderly. Although universal compulsory education up to grade 9 was achieved in 1980, only 21.2 percent of the population aged 25-64 had undergone secondary education, compared to an EU average of 65.7 percent. Portugal's higher education system currently consists of 14 state universities and 14 private universities, 15 state polytechnic institutions, one Catholic university, and one military academy. All in all, Portugal spends a greater percentage of its state budget on education than most EU member states. Despite this high level of expenditure, the troubled Portuguese education system does not perform well. Early leaving and repetition rates are among the highest among EU member states.After the Revolution of 25 April 1974, Portugal created a National Health Service, which today consists of 221 hospitals and 512 medical centers employing 33,751 doctors and 41,799 nurses. Like its education system, Portugal's medical system is inefficient. There are long waiting lists for appointments with specialists and for surgical procedures.Structural changes in Portugal's economy and society mean that social life in Portugal is not too different from that in other EU member states. A mass consumption society has been created. Televisions, telephones, refrigerators, cars, music equipment, mobile phones, and personal computers are commonplace. Sixty percent of Portuguese households possess at least one automobile, and 65 percent of Portuguese own their own home. Portuguese citizens are more aware of their legal rights than ever before. This has resulted in a trebling of the number of legal proceeding since 1960 and an eight-fold increase in the number of lawyers. In general, Portuguese society has become more permissive and secular; the Catholic Church and the armed forces are much less influential than in the past. Portugal's population is also much more culturally, religiously, and ethnically diverse, a consequence of the coming to Portugal of hundreds of thousands of immigrants, mainly from former African colonies.Portuguese are becoming more cosmopolitan and sophisticated through the impact of world media, the Internet, and the World Wide Web. A prime case in point came in the summer and early fall of 1999, with the extraordinary events in East Timor and the massive Portuguese popular responses. An internationally monitored referendum in East Timor, Portugal's former colony in the Indonesian archipelago and under Indonesian occupation from late 1975 to summer 1999, resulted in a vote of 78.5 percent for rejecting integration with Indonesia and for independence. When Indonesian prointegration gangs, aided by the Indonesian military, responded to the referendum with widespread brutality and threatened to reverse the verdict of the referendum, there was a spontaneous popular outpouring of protest in the cities and towns of Portugal. An avalanche of Portuguese e-mail fell on leaders and groups in the UN and in certain countries around the world as Portugal's diplomats, perhaps to compensate for the weak initial response to Indonesian armed aggression in 1975, called for the protection of East Timor as an independent state and for UN intervention to thwart Indonesian action. Using global communications networks, the Portuguese were able to mobilize UN and world public opinion against Indonesian actions and aided the eventual independence of East Timor on 20 May 2002.From the Revolution of 25 April 1974 until the 1990s, Portugal had a large number of political parties, one of the largest Communist parties in western Europe, frequent elections, and endemic cabinet instability. Since the 1990s, the number of political parties has been dramatically reduced and cabinet stability increased. Gradually, the Portuguese electorate has concentrated around two larger parties, the right-of-center Social Democrats (PSD) and the left-of-center Socialist (PS). In the 1980s, these two parties together garnered 65 percent of the vote and 70 percent of the seats in parliament. In 2005, these percentages had risen to 74 percent and 85 percent, respectively. In effect, Portugal is currently a two-party dominant system in which the two largest parties — PS and PSD—alternate in and out of power, not unlike the rotation of the two main political parties (the Regenerators and the Historicals) during the last decades (1850s to 1880s) of the liberal constitutional monarchy. As Portugal's democracy has consolidated, turnout rates for the eligible electorate have declined. In the 1970s, turnout was 85 percent. In Portugal's most recent parliamentary election (2005), turnout had fallen to 65 percent of the eligible electorate.Portugal has benefited greatly from membership in the EU, and whatever doubts remain about the price paid for membership, no Portuguese government in the near future can afford to sever this connection. The vast majority of Portuguese citizens see membership in the EU as a "good thing" and strongly believe that Portugal has benefited from membership. Only the Communist Party opposed membership because it reduces national sovereignty, serves the interests of capitalists not workers, and suffers from a democratic deficit. Despite the high level of support for the EU, Portuguese voters are increasingly not voting in elections for the European Parliament, however. Turnout for European Parliament elections fell from 40 percent of the eligible electorate in the 1999 elections to 38 percent in the 2004 elections.In sum, Portugal's turn toward Europe has done much to overcome its backwardness. However, despite the economic, social, and political progress made since 1986, Portugal has a long way to go before it can claim to be on a par with the level found even in Spain, much less the rest of western Europe. As Portugal struggles to move from underde-velopment, especially in the rural areas away from the coast, it must keep in mind the perils of too rapid modern development, which could damage two of its most precious assets: its scenery and environment. The growth and future prosperity of the economy will depend on the degree to which the government and the private sector will remain stewards of clean air, soil, water, and other finite resources on which the tourism industry depends and on which Portugal's world image as a unique place to visit rests. Currently, Portugal is investing heavily in renewable energy from solar, wind, and wave power in order to account for about 50 percent of its electricity needs by 2010. Portugal opened the world's largest solar power plant and the world's first commercial wave power farm in 2006.An American documentary film on Portugal produced in the 1970s described this little country as having "a Past in Search of a Future." In the years after the Revolution of 25 April 1974, it could be said that Portugal is now living in "a Present in Search of a Future." Increasingly, that future lies in Europe as an active and productive member of the EU.54 clock synchronization

СИНХРОНИЗАЦИЯ ВРЕМЕНИ СОГЛАСНО СТАНДАРТУ IEEE 1588
Автор: Андреас Дреер (Hirschmann Automation and Control)
Вопрос синхронизации устройств по времени важен для многих распределенных систем промышленной автоматизации. При использовании протокола Precision Time Protocol (PTP), описанного стандартом IEEE 1588, становится возможным выполнение синхронизации внутренних часов устройств, объединенных по сети Ethernet, с погрешностями, не превышающими 1 микросекунду. При этом к вычислительной способности устройств и пропускной способности сети предъявляются относительно низкие требования. В 2008 году была утверждена вторая редакция стандарта (IEEE 1588-2008 – PTP версия 2) с рядом внесенных усовершенствований по сравнению с первой его редакцией.
ЗАЧЕМ НЕОБХОДИМА СИНХРОНИЗАЦИЯ УСТРОЙСТВ ПО ВРЕМЕНИ?
Во многих системах должен производиться отсчет времени. О неявной системе отсчета времени можно говорить тогда, когда в системе отсутствуют часы и ход времени определяется процессами, протекающими в аппаратном и программном обеспечении. Этого оказывается достаточно во многих случаях. Неявная система отсчета времени реализуется, к примеру, передачей сигналов, инициирующих начало отсчета времени и затем выполнение определенных действий, от одних устройств другим.
Система отсчета времени считается явной, если показания времени в ней определяются часами. Указанное необходимо для сложных систем. Таким образом, осуществляется разделение процедур передачи данных о времени и данных о процессе.
Два эффекта должны быть учтены при настройке или синхронизации часов в отдельных устройствах. Первое – показания часов в отдельных устройствах изначально отличаются друг от друга (смещение показаний времени друг относительно друга). Второе – реальные часы не производят отсчет времени с одинаковой скоростью. Таким образом, требуется проводить постоянную корректировку хода самых неточных часов.
Существуют различные способы синхронизации часов в составе отдельных устройств, объединенных в одну информационную сеть. Наиболее известные способы – это использование протокола NTP (Network Time Protocol), а также более простого протокола, который образован от него – протокола SNTP (Simple Network Time Protocol). Данные методы широко распространены для использования в локальных сетях и сети Интернет и позволяют обеспечивать синхронизацию времени с погрешностями в диапазоне миллисекунд. Другой вариант – использование радиосигналов с GPS спутников. Однако при использовании данного способа требуется наличие достаточно дорогих GPS-приемников для каждого из устройств, а также GPS-антенн. Данный способ теоретически может обеспечить высокую точность синхронизации времени, однако материальные затраты и трудозатраты обычно препятствуют реализации такого метода синхронизации.
Другим решением является передача высокоточного временного импульса (например, одного импульса в секунду) каждому отдельному устройству по выделенной линии. Реализация данного метода влечет за собой необходимость создания выделенной линии связи к каждому устройству.
Последним методом, который может быть использован, является протокол PTP (Precision Time Protocol), описанный стандартом IEEE 1588. Протокол был разработан со следующими целями:
- Обеспечение синхронизация времени с погрешностью, не превышающей 1 микросекунды.
-
Предъявление минимальных требований к производительности процессоров устройств и к пропускной способности линии связи, что позволило бы обеспечить реализацию протокола в простых и дешевых устройствах.
- Предъявление невысоких требований к обслуживающему персоналу.
- Возможность использования в сетях Ethernet, а также в других сетях.
- Спецификация его как международного стандарта.
ОБЛАСТИ ПРИМЕНЕНИЯ ПРОТОКОЛА PTP
Протокол PTP может быть применен в различного рода системах. В системах автоматизации, протокол PTP востребован везде, где требуется точная синхронизация устройств по времени. Протокол позволяет синхронизировать устройства в робототехнике или печатной промышленности, в системах осуществляющих обработку бумаги и упаковку продукции и других областях.
В общем и целом в любых системах, где осуществляется измерение тех или иных величин и их сравнение с величинами, измеренными другими устройствами, использование протокола PTP является популярным решением. Системы управления турбинами используют протокол PTP для обеспечения более эффективной работы станций. События, происходящие в различных частях распределенных в пространстве систем, определяются метками точного времени и затем для целей архивирования и анализа осуществляется их передача на центры управления. Геоученые используют протокол PTP для синхронизации установок мониторинга сейсмической активности, удаленных друг от друга на значительные расстояния, что предоставляет возможность более точным образом определять эпицентры землетрясений. В области телекоммуникаций рассматривают возможность использования протокола PTP для целей синхронизации сетей и базовых станций. Также синхронизация времени согласно стандарту IEEE 1588 представляет интерес для разработчиков систем обеспечения жизнедеятельности, систем передачи аудио и видео потоков и может быть использована в военной промышленности.
В электроэнергетике протокол PTPv2 (протокол PTP версии 2) определен для синхронизации интеллектуальных электронных устройств (IED) по времени. Например, при реализации шины процесса, с передачей мгновенных значений тока и напряжения согласно стандарту МЭК 61850-9-2, требуется точная синхронизация полевых устройств по времени. Для реализации систем защиты и автоматики с использованием сети Ethernet погрешность синхронизации данных различных устройств по времени должна лежать в микросекундном диапазоне.
Также для реализации функций синхронизированного распределенного векторного измерения электрических величин согласно стандарту IEEE C37.118, учета, оценки качества электрической энергии или анализа аварийных событий необходимо наличие устройств, синхронизированных по времени с максимальной точностью, для чего может быть использован протокол PTP.
Вторая редакция стандарта МЭК 61850 определяет использование в системах синхронизации времени протокола PTP. Детализация профиля протокола PTP для использования на объектах электроэнергетики (IEEE Standard Profile for Use of IEEE 1588 Precision Time Protocol in Power System Applications) в настоящее время осуществляется рабочей группой комитета по релейной защите и автоматике организации (PSRC) IEEE.
В 2005 году была начата работа по изменению стандарта IEEE1588-2002 с целью расширения возможных областей его применения (телекоммуникации, беспроводная связь и в др.). Результатом работы стало новое издание IEEE1588-2008, которое доступно с марта 2008 со следующими новыми особенностями:
- Усовершенствованные алгоритмы для обеспечения погрешностей в наносекундном диапазоне.
- Повышенное быстродействие синхронизации времени (возможна более частая передача сообщений синхронизации Sync).
- Поддержка новых типов сообщений.
- Ввод однорежимного принципа работы (не требуется передачи сообщений типа FollowUp).
- Ввод поддержки функции т.н. прозрачных часов для предотвращения накопления погрешностей измерения при каскадной схеме соединения коммутаторов.
- Ввод профилей, определяющих настройки для новых областей применения.
- Возможность назначения на такие транспортные механизмы как DeviceNet, PROFInet и IEEE802.3/Ethernet (прямое назначение).
- Ввод структуры TLV (тип, длина, значение) для расширения возможных областей применения стандарта и удовлетворения будущих потребностей.
- Ввод дополнительных опциональных расширений стандарта.
ПРИНЦИП ФУНКЦИОНИРОВАНИЯ СИСТЕМ НА ОСНОВЕ ПРОТОКОЛА PTP
В системах, где используется протокол PTP, различают два вида часов: ведущие часы и ведомые часы. Ведущие часы, в идеале, контролируются либо радиочасами, либо GPS-приемниками и осуществляют синхронизацию ведомых часов. Часы в конечном устройстве, неважно ведущие ли они или ведомые, считаются обычными часами; часы в составе устройств сети, выполняющих функцию передачи и маршрутизации данных (например, в Ethernet-коммутаторах), считаются граничными часами.
Процедура синхронизации согласно протоколу PTP подразделяется на два этапа. На первом этапе осуществляется коррекция разницы показаний времени между ведущими и ведомыми часами – то есть осуществляется так называемая коррекция смещения показаний времени. Для этого ведущее устройство осуществляет передачу сообщения для целей синхронизации времени Sync ведомому устройству (сообщение типа Sync). Сообщение содержит в себе текущее показание времени ведущих часов и его передача осуществляется периодически через фиксированные интервалы времени. Однако поскольку считывание показаний ведущих часов, обработка данных и передача через контроллер Ethernet занимает некоторое время, информация в передаваемом сообщении к моменту его приема оказывается неактуальной. Одновременно с этим осуществляется как можно более точная фиксация момента времени, в который сообщение Sync уходит от отправителя, в составе которого находятся ведущие часы (TM1). Затем ведущее устройство осуществляет передачу зафиксированного момента времени передачи сообщения Sync ведомым устройствам (сообщение FollowUp). Те также как можно точнее осуществляют измерение момента времени приема первого сообщения (TS1) и вычисляют величину, на которую необходимо выполнить коррекцию разницы в показаниях времени между собою и ведущим устройством соответственно (O) (см. рис. 1 и рис. 2). Затем непосредственно осуществляется коррекция показаний часов в составе ведомых устройств на величину смещения. Если задержки в передачи сообщений по сети не было, то можно утверждать, что устройства синхронизированы по времени.
На втором этапе процедуры синхронизации устройств по времени осуществляется определение задержки в передаче упомянутых выше сообщений по сети между устройствами. Указанное выполняется при использовании сообщений специального типа. Ведомое устройство отправляет так называемое сообщение Delay Request (Запрос задержки в передаче сообщения по сети) ведущему устройству и осуществляет фиксацию момента передачи данного сообщения. Ведущее устройство фиксирует момент приема данного сообщения и отправляет зафиксированное значение в сообщении Delay Response (Ответное сообщение с указанием момента приема сообщения). Исходя из зафиксированных времен передачи сообщения Delay Request ведомым устройством и приема сообщения Delay Response ведущим устройством производится оценка задержки в передачи сообщения между ними по сети. Затем производится соответствующая коррекция показаний часов в ведомом устройстве. Однако все упомянутое выше справедливо, если характерна симметричная задержка в передаче сообщения в обоих направлениях между устройствами (то есть характерны одинаковые значения в задержке передачи сообщений в обоих направлениях).
Задержка в передачи сообщения в обоих направлениях будет идентичной в том случае, если устройства соединены между собой по одной линии связи и только. Если в сети между устройствами имеются коммутаторы или маршрутизаторы, то симметричной задержка в передачи сообщения между устройствами не будет, поскольку коммутаторы в сети осуществляют сохранение тех пакетов данных, которые проходят через них, и реализуется определенная очередность их передачи. Эта особенность может, в некоторых случаях, значительным образом влиять на величину задержки в передаче сообщений (возможны значительные отличия во временах передачи данных). При низкой информационной загрузке сети этот эффект оказывает малое влияние, однако при высокой информационной загрузке, указанное может значительным образом повлиять на точность синхронизации времени. Для исключения больших погрешностей был предложен специальный метод и введено понятие граничных часов, которые реализуются в составе коммутаторов сети. Данные граничные часы синхронизируются по времени с часами ведущего устройства. Далее коммутатор по каждому порту является ведущим устройством для всех ведомых устройств, подключенных к его портам, в которых осуществляется соответствующая синхронизация часов. Таким образом, синхронизация всегда осуществляется по схеме точка-точка и характерна практически одинаковая задержка в передаче сообщения в прямом и обратном направлении, а также практическая неизменность этой задержки по величине от одной передачи сообщения к другой.
Хотя принцип, основанный на использовании граничных часов показал свою практическую эффективность, другой механизм был определен во второй версии протокола PTPv2 – механизм использования т. н. прозрачных часов. Данный механизм предотвращает накопление погрешности, обусловленной изменением величины задержек в передаче сообщений синхронизации коммутаторами и предотвращает снижение точности синхронизации в случае наличия сети с большим числом каскадно-соединенных коммутаторов. При использовании такого механизма передача сообщений синхронизации осуществляется от ведущего устройства ведомому, как и передача любого другого сообщения в сети. Однако когда сообщение синхронизации проходит через коммутатор фиксируется задержка его передачи коммутатором. Задержка фиксируется в специальном поле коррекции в составе первого сообщения синхронизации Sync или в составе последующего сообщения FollowUp (см. рис. 2). При передаче сообщений Delay Request и Delay Response также осуществляется фиксация времени задержки их в коммутаторе. Таким образом, реализация поддержки т. н. прозрачных часов в составе коммутаторов позволяет компенсировать задержки, возникающие непосредственно в них.
Если необходимо использование протокола PTP в системе, должен быть реализован стек протокола PTP. Это может быть сделано при предъявлении минимальных требований к производительности процессоров устройств и к пропускной способности сети. Это очень важно для реализации стека протокола в простых и дешевых устройствах. Протокол PTP может быть без труда реализован даже в системах, построенных на дешевых контроллерах (32 бита).
Единственное требование, которое необходимо удовлетворить для обеспечения высокой точности синхронизации, – как можно более точное измерение устройствами момента времени, в который осуществляется передача сообщения, и момента времени, когда осуществляется прием сообщения. Измерение должно производится максимально близко к аппаратной части (например, непосредственно в драйвере) и с максимально возможной точностью. В реализациях исключительно на программном уровне архитектура и производительность системы непосредственно ограничивают максимально допустимую точность.
При использовании дополнительной поддержки аппаратного обеспечения для присвоения меток времени, точность может быть значительным образом повышена и может быть обеспечена ее виртуальная независимость от программного обеспечения. Для этого необходимо использование дополнительной логики, которая может быть реализована в программируемой логической интегральной схеме или специализированной для решения конкретной задачи интегральной схеме на сетевом входе.
Компания Hirschmann – один из первых производителей, реализовавших протокол PTP и оптимизировавших его использование. Компанией был разработан стек, максимально эффективно реализующий протокол, а также чип (программируемая интегральная логическая схема), который обеспечивает высокую точность проводимых замеров.
В системе, в которой несколько обычных часов объединены через Ethernet-коммутатор с функцией граничных часов, была достигнута предельная погрешность +/- 60 нс при практически полной независимости от загрузки сети и загрузки процессора. Также компанией была протестирована система, состоящая из 30 каскадно-соединенных коммутаторов, обладающих функцией поддержки т.н. прозрачных часов и были зафиксированы погрешности менее в пределах +/- 200 нс.
Компания Hirschmann Automation and Control реализовала протоколы PTP версии 1 и версии 2 в промышленных коммутаторах серии MICE, а также в серии монтируемых на стойку коммутаторов MACH100.
Протокол PTP во многих областях уже доказал эффективность своего применения. Можно быть уверенным, что он получит более широкое распространение в течение следующих лет и что многие решения при его использовании смогут быть реализованы более просто и эффективно чем при использовании других технологий.

actuator
In electrical engineering, the term actuator refers to a mechanism that causes a device to be turned on or off, adjusted or moved, usually in response to an electrical signal. In some literature the terms actor or effector are also used. The term “effector” is preferred by programmers, whereas engineers tend to favor “actuator.”
An example of an actuator is a motor that closes blinds in response to a signal from a sunlight detector.
Actuators enable computers to control complex manufacturing processes without human intervention or supervision.

- расположены так, чтобы ими можно было пользоваться без возникновения сомнений и потерь времени на выяснение их назначения;
- сконструированы так, чтобы перемещение органа управления согласовывалось с их воздействием;

привод
Устройство для приведения в действие машин и механизмов.
Примечание
Привод состоит из источника энергии, механизма для передачи энергии (движения) и аппаратуры управления. Источником энергии служит двигатель (тепловой, электрический, пневматический, гидравлический и др.) или устройство, отдающее заранее накопленную механическую энергию (пружинный, инерционный, гиревой механизм и др.). В некоторых случаях привод осуществляется за счет мускульной силы. По характеру распределения энергии различают групповой, индивидуальный и многодвигательный привод. По назначению привод машин разделяют на стационарный, т.е. установленный неподвижно на раме или фундаменте; передвижной, используемый на движущихся рабочих машинах; транспортный, применяемый для различных транспортных средств. В производстве применяются также гидропривод машин и пневмопривод.

привод контактного аппарата
Устройство, предназначенное для создания или передачи силы, воздействующей на подвижные части контактного аппарата для выполнения функции этого аппарата.
[ ГОСТ 17703-72]
привод
Устройство, предназначенное для создания и передачи силы, воздействующей на подвижные части выключателя для выполнения его функций, а также для удержания выключателя в конечном положении.
[ ГОСТ Р 52565-2006]Приводы являются аппаратами для включения и удержания во включенном положении, а также отключения коммутационных аппаратов (масляного выключателя, выключателя нагрузки или разъединителя).
С помощью приводов осуществляется ручное, автоматическое и дистанционное управление коммутационными аппаратами.
По роду используемой энергии приводы разделяются- на ручные,
- пружинные,
- электромагнитные,
- электродвигательные,
- пневматические.
По роду действия приводы бывают
- прямого действия
- косвенного действия.
В приводах прямого действия движение включающего устройства передается непосредственно на приводной механизм выключателя в момент подачи импульса от источника энергии. Такие приводы потребляют большое количество энергии.
В приводах косвенного действия энергия, необходимая для включения, предварительно запасается в специальных устройствах: маховиках, пружинах, грузах и т. д.
[Цигельман И. Е. Электроснабжение гражданских зданий и коммунальных предприятий: Учеб. для электромеханич. спец. техникумов. - М.: Высш. шк. 1988.]
Приводы служат для включения, удержания во включенном положении и отключения разъединителей и выключателей.
Основные требования, предъявляемые к приводу выключателя, состоят в том, что каждый привод должен развивать мощность, достаточную для включения выключателя при самых тяжелых условиях работы (включение на короткое замыкание, пониженное напряжение питания), и быть быстродействующим, т. е. производить включение за весьма малый промежуток времени. При медленном включении на существующее в сети КЗ возможно приваривание контактов.
При включении выключателя совершается большая работа по преодолению сопротивления отключающих пружин, сопротивления упругих частей контактов, трения в механизме, сопротивления масла движению подвижных частей выключателя, электродинамических сил, препятствующих включению, и др.
При отключении привод выключателя совершает небольшую работу, необходимую только для освобождения запорного механизма, так как отключение выключателя происходит под действием его отключающих пружин.
В зависимости от рода энергии, используемой для включения, приводы разделяются на ручные, грузовые, пружинно-грузовые, пружинные, электромагнитные, пневматические и гидравлические.
К наиболее простым относятся ручные приводы, не требующие специального источника электроэнергии для подготовки операции включения. Однако эти приводы имеют ряд существенных недостатков: не позволяют осуществлять дистанционное включение, не могут быть применены в схемах АВР (автоматического включения резерва) и АПВ (автоматического повторного включения), требуют приложения значительной мускульной силы оператора и не позволяют получить высокие скорости подвижных контактов выключателя, необходимые при больших токах КЗ.
Более совершенными, имеющими большие возможности, но в то же время и более сложными являются грузовые и пружинные приводы, которые обеспечивают значительно более высокие скорости включения выключателя по сравнению с ручными. Это в свою очередь позволяет увеличить включающую способность выключателя. Грузовые и пружинные приводы включают выключатель за счет заранее накопленной энергии поднятого груза или заведенной пружины. Накопление достаточного количества энергии может производиться в течение сравнительно большого промежутка времени (десятки секунд), поэтому мощность электродвигателей таких приводов может быть небольшой (0,1—0.3 кВт).
Электромагнитные приводы включают выключатель за счет энергии включающего электромагнита. Электромагнитные приводы предназначены для работы на постоянном токе. Питание их осуществляют от аккумуляторных батарей или выпрямителей. По способу питания энергией приводы подразделяют на две группы: прямого и косвенного действия.
У приводов прямого действия энергия, расходуемая на включение, сообщается приводу во время процесса включения. К приводам прямого действия относятся ручные с использованием мускульной силы человека и электромагнитные или соленоидные приводы. Работа приводов косвенного действия основана на предварительно запасаемой энергии. К таким приводам относятся грузовые, пружинно-грузовые и пружинные приводы, а также пневматические и гидравлические. Последние два типа приводов не нашли широкого применения для выключателей 6—10 кВ и поэтому нами не рассматриваются.
Приводы прямого действия по конструкции более просты по сравнению с приводами косвенного действия, и в этом их преимущество. Однако поскольку приводы прямого действия питаются от источника энергии непосредственно во время процесса включения выключателя, то потребляемая ими мощность во много раз больше, чем у приводов косвенного действия. Это — существенный недостаток приводов прямого действия.
Ко всем приводам выключателей предъявляют требование наличия механизма свободного расцепления, т. е. возможности освобождения выключателя от связи с удерживающим и заводящим механизмами привода при срабатывании отключающего устройства и отключения выключателя под действием своих отключающих пружин. Современные приводы имеют свободное расцепление почти на всем ходу контактов, т. е. практически в любой момент от начала включения может произойти отключение. Это особенно важно при включении на КЗ. В этом случае отключение произойдет в первый же момент возникновения дуги, что предотвратит опасность сильного оплавления и сваривания контактов.[http://forca.ru/stati/podstancii/privody-razediniteley-i-maslyanyh-vyklyuchateley-6-10-kv-i-ih-remont.html]
