1one

Изобретение относитс к автоматике и вычислительной технике.This invention relates to automation and computing.

Известны коммутаторы, содержащие регистр, триггэр и элемент ИЛИ l Однако известное устройство характеризуетс низкой надежностью.Switches are known that contain a register, a trigger, and an OR element. However, the known device is characterized by low reliability.

Наиболее близким по технической сущности к изобретению влетс коммутатор , содержащий сдвиговый регистр, выходы которого соединены с выходны-п fQ ми шинами, а управл ющий вход подключен к выходу элемента ИЛИ, первый вход которого соединен с управл ющей шиной, а также триггер f2}.The closest in technical essence to the invention is a switch containing a shift register, the outputs of which are connected to the output-fQ buses, and a control input connected to the output of the OR element, the first input of which is connected to the control bus, as well as the trigger f2}.

К недостаткам данного устройства is относитс также низка надежность.The disadvantages of this device is also low reliability.

Цель изобретени - повышение надежности коммутатора.The purpose of the invention is to increase the reliability of the switch.

Указанна цель достигаетс тем, что в коммутатор, содержащий сдвиго- -20 вый регистр, выходы которого соединены с выходными шинами, а управл ющий вход подключен к выходу элемента ИЛИ, первый вход которого соединенThis goal is achieved by the fact that the switch contains a shift -20 register, the outputs of which are connected to the output buses, and the control input is connected to the output of the OR element, the first input of which is connected

с управл ющей шиной, а также триггер, введены счет.чик, генератор и элемент 2 И-ИЛИ-НЕ, каждый из первых входов которого соединен с соответствующим выходом сдвигового регистра, а каждый из вторых входов подключен к одноименной дополнительной управл ющей шине, при этом выход элемента 2ИИЛИ-НЕ соединен с дополнительной выходной шиной и с входом остановки генератора, запускающий вход которого подключен к информационному входу сдвигового регистра и единичному выходу триггера, единичный вход которого соединен с шиной запуска, а нулевой вход - с последним выходом сдвигового регистра, при этом выход генератора подключен к второму входу элемента ИЛИ, выход которого соединен со входом счетчика.with a control bus, as well as a trigger, a counting device, an oscillator, and an AND-OR-NOT element 2 are entered, each of the first inputs of which is connected to the corresponding output of the shift register, and each of the second inputs is connected to the corresponding additional control bus, This output element 2ILI-NOT connected to an additional output bus and to the generator stop input, the triggering input of which is connected to the information input of the shift register and the single output of the trigger, the single input of which is connected to the trigger bus, and zero input d - with the last output of the shift register, while the generator output is connected to the second input of the OR element, the output of which is connected to the counter input.

Claims

The drawing shows the functional diagram of the proposed switch. The circuit includes a shift register T, the outputs of which are connected to busbars 2, and a control input connected to the output of the element OR 3, the first input of which is connected to the control bus k, trigger 5. element 2I-OR-HE 6, each of the first inputs which is connected to the corresponding output of the shift register 1, and each of the second inputs is connected to the control bus 7 of the same name, the output of element 2I-OR-NOT 6 is connected to the output bus 8 and to the input of the generator 9 whose trigger input is connected to the information input of the shift register 1 and the single output of the trigger 5, the single input of which is connected to the start bus 10, and the zero input to the last output of the shift register 1, the output of the generator 9 is connected to the second input of the OR element 3, the output of which is connected to the input of the counter 11. The switch works as follows. When a pulse arrives at the trigger bus 10 at the single input of trigger 5, the generator 9 is switched to the operating state and the unit is written to the first digit of the shift register 1. At the first output of the shift register 1, the signal necessary to turn on the object appears. If a single logical level is fed to the corresponding input of element 2I-OR-NOT over the control bus 7 of the same name indicating that this switch channel must be enabled, then the output of element 2I-OR-NOT 6 has a zero logic level that prevents the start generator 9. After the channel has been processed, a pulse arrives on the control bus, which is fed to the shift register 1 through the OR 3 element, and the unit moves to the second bit. Suppose that this channel is to be skipped. To do this, a zero logic level is supplied via the second control bus 7- In this case, at the output of element 2I-OR-NOT 6, we have a single logic level and generator 9 begins to generate pulses that through the element OR 3 arrive at the shift register 1 as pulses shear. After the first pulse, the unit moves to the third bit of the shift register 1, and if a single logic level is applied to the third control bus 7, the generation stops and the next channel is processed. The number of pulses arriving at counter 11 through the element OR 3, as well as the readings of counter 11, always correspond to the channel number of the switch to be processed at a given time. Thus, due to the introduction. the counter, generator and element 2I-OR-NOT in the present invention as compared with the known, the reliability of the switch is improved. Claim switch containing a shift register, the outputs of which are connected to the output buses, and a control input connected to the output of the OR element, the first input of which is connected to the control bus, and a trigger, characterized in that, in order to improve reliability, a counter is entered , the generator and element 2IILI-NOT, each of the first inputs of which is connected to the corresponding output of the shift register, and each of the second inputs is connected to the similar additional control bus, at 3tCM the output of element 2I-ILINE is connected to an additional output bus and a generator stop input, the trigger input of which is connected to the information input of the shift register and a single trigger output, the single input of which is connected to the start bus, and the zero input - with the last output of the shift register, while the generator output is connected to the second element input OR, the output of which is connected to the input of the counter.
