На чертеже приведена стабилизированная система питания.The drawing shows a stabilized power system.

Система содержит входы ВИПов 1, которые подключены к первичной сети через управляемые контакты узлов 2 защиты, а выходы через узлы 2 защиты подключены к входам регистров 3. Выходы регистров 3 соединены с входами логических элементов' ИЛИ 4. Элементы 1-4 входят в состав групп источников 5 и б питания. Выходы регистров 3 подключены к первым входам ЦВМ 7, к вторым входам подключены выхода элементов ИЛИ 4, а выход ЦВМ 7 подключен к входам исполнительного узла 8 с индикаторами и реле, который осуществляет раздельное подключение групп источников к шине первичного питания.The system contains the inputs of VIPs 1, which are connected to the primary network through the managed contacts of the protection nodes 2, and the outputs through the protection nodes 2 are connected to the inputs of the registers 3. The outputs of the registers 3 are connected to the inputs of the logical elements' OR 4. Elements 1-4 are part of the groups 5 and 6 power sources. The outputs of the registers 3 are connected to the first inputs of the digital computer 7, the outputs of the OR elements 4 are connected to the second inputs, and the output of the digital computer 7 is connected to the inputs of the executive unit 8 with indicators and relays, which separately connects the groups of sources to the primary power bus.

Работа устройства осуществляется следующим образом.The operation of the device is as follows.

Узел 2 защиты производит непрерывный контроль выходных параметров ВИПов 1. При отключении выходных параметров какого-либо ВИПа за допустимые пределы, соответствующий узел защиты формирует сигнал, поступающий на управляемый контакт для отключения входа этого ВИПа от сети первичного напряжения, а также логический, сигнал неисправности, который подается на соответствующий вход сдвигового регистра 3 с параллельной записью, в котором хранится информация об индивидуальной неисправности ВИПов 1. Элемент ИЛИ 4, подключенный к выходам’ регистра 3 неисправности, формирует сигнал ¹’Общая неисправность группы источников питания’’ и вы; ает этот сигнал на второй вход ЦВМ 7, которая осуществляет периодический опрос своего второго входа для контроля наличия неисправности в данной группе источников. При наличии на одном из своих вторых входов сигнала *'Общая неисправность'’ ЦВМ 7 осуществляет запрос последовательным кодом информации с регистра 3 данной группы источников, производит анализ содержимого регистра, в зависимости от которого или продолжает работу по прерванной программе без вывода группы источников в ремонт (если отказ ВИПов не влияет на функционирование аппаратуры на данном участье программы), или формирует сигнал, по которому реле в исполнительном узле 8 осуществляет подачу напряжения .на соответствующий индикатор, ''Неисправность группового источника'' и отключает отказавшую группу источников от шины первичного питания. Для локализации отказавшего ВИПа в групповом источнике питания оператор выводит содержимое регистра 3 на элементы индикации ЦВМ.The protection node 2 performs continuous monitoring of the output parameters of the VIPs 1. When the output parameters of any VIP are turned off within the permissible limits, the corresponding protection node generates a signal supplied to the controlled contact to disconnect the input of this VIP from the primary voltage network, as well as a logical, fault signal, which is fed to the corresponding input of the shift register 3 with parallel recording, which stores information about individual malfunctions of VIPs 1. OR element 4 connected to the outputs of 'register 3 malfunctions, generates a signal ¹ 'General malfunction of the group of power supplies''' and you; This signal is sent to the second input of digital computer 7, which periodically polls its second input to monitor for a malfunction in this group of sources. If there is a signal * “General malfunction” on one of its second inputs, the digital computer 7 queries the serial code of information from register 3 of this group of sources, analyzes the contents of the register, depending on which it continues to work on the interrupted program without displaying the group of sources for repair (if the failure of the VIPs does not affect the functioning of the equipment at this part of the program), or generates a signal by which the relay in the actuation unit 8 supplies voltage. to the corresponding indicator, '' Nei group rectified source '' and disables the failed group of sources from a primary power bus. To localize a failed VIP in a group power supply, the operator displays the contents of register 3 on the display elements of the digital computer.

С целью повышения достоверности результатов контроля напряжение питания регистра 3 и элемента ИЛИ 4 берется из соседней группы источников.In order to increase the reliability of the control results, the voltage of the register 3 and the OR element 4 is taken from a neighboring group of sources.

Для повышения надежности работы в системе может быть использована многоканальная ЦВМ, причем каждый из каналов может иметь равноправный доступ к регистру неисправности и к входам исполнительного органа.To increase the reliability of work in the system, a multi-channel digital computer can be used, and each of the channels can have equal access to the fault register and to the inputs of the executive body.

Таким образом, предлагаемая система питания повышает эффективность использования источников питания, а также всей системы в целом за счет возможности разделения во времени момента отказа и момента ремонта (замены ) данного ВИПа и облегчает работу оператора по наблюдению и анализу сигналов неисправности ВИП путем использования для этой цели ЦВМ. При введении в состав группового источника резервных ВИПов, исполнительный узел способен, в принципе, по специальной команде из ЦВМ производить замену неисправного ВИПа на ВИП из резерва путем перекоммутации связей,что повышает надежность системы.Thus, the proposed power system improves the efficiency of use of power sources, as well as the entire system as a whole due to the possibility of separation in time of the time of failure and the time of repair (replacement) of this VIP and facilitates the operator’s work on observing and analyzing VIP fault signals by using for this purpose Digital computer When introducing backup VIPs into the group source, the executive unit is capable, in principle, by a special command from the digital computer, to replace the faulty VIP with the VIP from the reserve by reconnecting communications, which increases the reliability of the system.

Claims

The invention relates to electrical engineering and can be used to control the operation of secondary power sources (VIPs) of digital computing devices. The stabilized DC source with overload protection is known, which, when the output parameters of the power sources are exceeded by current or voltage, reliably disconnects the input circuits of the sources from the primary voltage.

In addition, the register and the OR element, which are part of one group of power sources, are connected to one of the sources that are part of another group of sources. The drawing shows a stabilized power system. The system contains the inputs of VIP 1, which are connected to the primary network through controlled contacts of the protection nodes 2, and the outputs through the protection nodes 2 are connected to the inputs of registers 3. The outputs of registers 3 are connected to the inputs of logical elements OR 4. Elements 1-4 are included in groups of sources 5 and b nutrition. The outputs of the registers 3 are connected to the first inputs of the digital computer 7, the outputs of the elements OR 4 are connected to the second inputs, and the output of the digital computer is connected to the inputs of the execution unit 8 with indicators and a relay that separately connects the source groups to the primary power bus. The operation of the device is as follows. The protection node 2 continuously monitors the output parameters of the VIPs. When the output parameters of a VIP are out of allowable limits, the corresponding protection node generates a signal arriving at the controlled contact for disconnecting the input of this VIP from the primary voltage, as well as a malfunction signal, which is fed to the corresponding input of the shift register 3 with a parallel record, in which information is stored on the individual malfunction of the VIPs. The OR element 4 connected to the output of the register 3 is not spravnosti generates signal groups The total power failure and you sources - flushes the signal to a second input of the digital computer 7 which performs a periodic poll its second input for monitoring the presence of a fault in the source group. If a common fault is present on one of its second inputs of the digital computer 7, it requests the serial code of information from register 3 of this group of sources, analyzes the contents of the register, depending on which it continues to work on the interrupted program without taking the source group for repair (if VIPov does not affect the functioning of the equipment on this program's part), or generates a signal according to which the relay in the execution unit 8 carries out voltage supply to the corresponding indicator, Neis group source equality and disables the failed group of sources of primary power bus. In order to localize the failed VIP in the group power source, the operator displays the contents of register 3 on the display elements of the digital computer. In order to increase the reliability of the monitoring results, the pianos of the register 3 and the element OR 4 are taken from a neighboring group of sources. To increase the reliability of work in the system, a multichannel digital computer can be used, each of the channels having equal access to the fault register and to the inputs of the executive body. Thus, the proposed power supply system increases the efficiency of use of power sources, as well as the entire system as a whole due to the possibility of separating in time the time of failure and the moment of repair (replacement) of this VIP and facilitates the operator's work in observing and analyzing the VIP malfunction signals by using goals of digital computers.
