And with the input of the amplifier, the output of which is connected to the second input of the first block of comparison and with the first inputs of the exchange channels, the first outputs of which are combined and connected to their second inputs, 20 the output of the first comparison unit is connected to the first input of the OR element, the output of which is connected to the input of the pulse shaper and is the first output of the device The second block is compared to 25 nya and the switch, the output of which is connected to the second input of the OR element, the amplifier output is connected to the first input of the switch, the other inputs of the switch are connected to the second * outputs of the ED channels, the first outputs of which are combined and connected to the first input of the second block comparison, the second input of which is connected to the output of the switch, the first input of which is the second output of the device.

На чертеже представлена структурная схема устройства для ввода-вывода информации.The drawing shows a structural diagram of a device for input-output information.

Устройство для ввода-вывода информации содержит блок 1 управления обменом, состоящий из последовательно соединенных формирователя 2 импульсов, усилителя 3 и первого блока 4 сравнения. Каналы 5 обмена, каждый из которых & состоит из Последовательно соединенных входного ключа 6, блока 7 обработки информации и выходного ключа 8, информационные шины 9, шины Ю управления, элемент ИЛИ II, первый выход 12 устройства, второй выход 13 устройства, блок 14 контроля, состоящий из последовательно соединенных коммутатора 15 и второго блока 16 сравнения.The device for input-output of information contains an exchange control unit 1, consisting of series-connected pulse shaper 2, amplifier 3 and the first comparison unit 4. Exchange channels 5, each of which & consists of a Serially connected input key 6, information processing unit 7 and output key 8, information buses 9, control buses U, OR element II, first output 12 of the device, second output 13 of the device, control unit 14 consisting of a series-connected switch 15 and a second comparison unit 16.

Устройство для ввода-вывода информа ции работает следующим образом.A device for input-output information operates as follows.

В устройстве осуществляется автоматическое разделение времени работы каналов обмена 5-1 - 5-К. Блок I управле ния обменом вырабатывает синхроимпульсы записи и считывания, а также адреса, указывающие на необходимость подключения тех или иных каналов 5 обмена, которые подаются с выхода усилителя 3 через шину 10 управления параллельно на все управляющие входы блоков 7 обработки информации, коммутатора 15 и на второй выход 13 устройства. Каждый блок 7 обработки информации, вырабатывает также управляющие сигналы только для соответствующего канала 5 обмена, которые формируются из сигналов, поступающих из формирователя 2 импульсов, и· используются для управления работой входного 6 и выходного 8 ключей соответствующего канала 5 обмена. Такая организация работы обеспечивает возможность подключения одного или нескольких выходных ключей, например 8-1, и подключение одного или нескольких входных ключей, например 6-2 и 6-3, г. е. информация из канала 5-1 обмена переписывается для дальнейшей обработки в каналы 5-2 и 5-3 обмена и т. д.The device automatically separates the operating time of the exchange channels 5-1 - 5-K. The exchange control unit I generates write and read clock pulses, as well as addresses indicating the need to connect certain exchange channels 5, which are supplied from the output of the amplifier 3 via the control bus 10 in parallel to all control inputs of the information processing units 7, switch 15, and the second output 13 of the device. Each information processing unit 7 also generates control signals only for the corresponding exchange channel 5, which are generated from signals coming from the pulse shaper 2, and are used to control the operation of input 6 and output 8 keys of the corresponding exchange channel 5. This organization of work provides the ability to connect one or more output keys, for example 8-1, and connect one or more input keys, for example 6-2 and 6-3, i.e., information from the exchange channel 5-1 is rewritten for further processing in channels 5-2 and 5-3 of the exchange, etc.

Одни входы второго блока 16 сравнения подключены постоянно к информационным шинам 9, вторые входы его подключены через коммутатор 15 к выходам блока 7 обработки информации контролируемого канала 5 обмена (который в данный момент работает в качестве источника информации, т. е. канал 5-1 обмена), .а на выходах 13 формируется код, указывающий номер контролируемого канала 5 обмена, т. е. код, равный единице. Такое подключение блока 14 контроля позволяет выявлять неисправности в работе выходных ключей контролируемого канала 5 обмена (в данном примере выходного ключа 8—1) и выявлять обрывы и короткие замыкания в информационных шинах 9.One of the inputs of the second comparison unit 16 is constantly connected to the information buses 9, its second inputs are connected via a switch 15 to the outputs of the information processing unit 7 of the controlled exchange channel 5 (which currently works as a source of information, i.e., the exchange channel 5-1 ), .a at outputs 13, a code is generated that indicates the number of the monitored exchange channel 5, i.e., a code equal to one. Such a connection of the control unit 14 makes it possible to detect malfunctions in the operation of the output keys of the monitored exchange channel 5 (in this example, the output key 8-1) and to detect breaks and short circuits in the information buses 9.

При этом, если выходной ключ 8 соответствующего контролируемого канала 5 обмена, исправен и в информационных шинах 9 нет коротких замыканий и обрывов, то на оба входа второго блока 16 сравнения попадает одинаковая .информация, что обеспечивает формирование на выходе его нулевого сигнала, указывающего на исправность соответствующих контролируемых устройств и цепей. При наличии неисправностей в выходном ключе 8 соответствующего контролируемого канала 5 обмена или в информационных шинах 9 на первые и вторые входы блока 16 сравнения подается разная информация, что обеспечивает формирование на выходе его сигнала 'Канал обмена неисправен'. Этот сигнал, пройдя элемент ИЛИ II, попадает на шину 12 (первый выход устройства), указывая на наличие $ неисправности, и одновременно этим сигналом осуществляется блокировка блока , 1 управления обменом. Аналогично работает и первый блок 4 сравнения, подключенный к входам и выходам усилителя 3 <0 блока I управления обменом.Moreover, if the output key 8 of the corresponding monitored exchange channel 5 is operational and there are no short circuits and breaks in the information buses 9, then the same information gets to both inputs of the second comparison unit 16, which ensures the formation of a zero signal at the output, indicating a good condition relevant monitored devices and circuits. If there are malfunctions in the output key 8 of the corresponding controlled exchange channel 5 or in the information buses 9, different information is supplied to the first and second inputs of the comparison unit 16, which ensures the formation of the 'Exchange channel is faulty' signal output. This signal, having passed the OR element II, gets on bus 12 (the first output of the device), indicating the presence of $ malfunction, and at the same time this signal blocks the block, 1 exchange control. The first comparison unit 4, connected to the inputs and outputs of the amplifier 3 <0 of the exchange control unit I, works similarly.

Положительный технический эффект от использования предлагаемого устройства заключается в упрощении устройства и повышении надежности его работы за 15 счет .введения блока контроля, общего для всех каналов обмена, что позволяет исключить блока сравнения из каналов. обмета и соответствующие им связи с блоками обработки информации и с инфор— 20 мационными шинами, а также заметить многовходовой элемент ИЛИ на двухвходовой. Таким образом, использование (предлагаемого устройства позволяет сок4 ратигь количество оборудования, исполь- 25 зуемого для контроля, а также сократить количество связей контролируемой аппаратуры с блоками, входящими в состав устройства, при количестве каналов обмета большем двух. 30A positive technical effect of using the proposed device is to simplify the device and increase the reliability of its operation for 15 due to the introduction of a control unit common to all exchange channels, which allows to exclude the comparison unit from the channels. objects and their corresponding connections with information processing units and with information buses, as well as notice a multi-input OR element on a two-input one. Thus, the use (of the proposed device allows juice4 to ratify the number of equipment used for control, as well as reduce the number of connections of the monitored equipment with the units included in the device, with the number of channels of obmet more than two. 30
