Устройство .содержит на передающей стороне генератор 1 тактовых импульсов , формирователь 2 импульса сброса инвертор 3, элемент И 4, регистр 5 сдвига, элементы 6 потенциальной раз в зки, замыкающие ключи 7, на приемной стороне формирователь 8 импульса сброса, регистр 9 сдвига, элементы И 10, первьй и второй проводы линии св зи 11,-117 формировател х 2 и 8 импульса сброса расположены резисторы 12 и 13, конденсаторы 14 и 15.The device contains on the transmitting side a clock pulse generator 1, a reset pulse shaper 2, an inverter 3, element 4, a shift register 5, potential breakout elements 6, closing keys 7, on the receiving side a reset pulse shaper 8, a shift register 9, elements And 10, the first and second wires of the communication line 11, -117 of the driver 2 and 8 of the reset pulse are resistors 12 and 13, capacitors 14 and 15.

Предлагаемое устройство работает следующим образом.The proposed device works as follows.

Дл функционировани устройства необходимо синхронное переключение регистров 5 и 9 сдвига на приемной и передающей сторонах, т.е. в любой момент времени единица должна быть записана в одинаковых разр дах обоих регистров. Так как оба регистра сдвига идентичны и входы которых подключены к выходу одного и того же генератора, то дл их синхронного переключени достаточно, чтобы перед началом работы оба регистра устанавливались в нулевое состо ние. При этом регистр сдвига на приемной сто- .роне должен включатьс первым, а на передающей стороне вторым и только после их установки в нулевое состо ние необходимо подавать импульсы с выхода генератора 1 тактовых импульсов .To operate the device, it is necessary to synchronously switch the shift registers 5 and 9 at the receiving and transmitting sides, i.e. at any time, the unit must be written in the same bits of both registers. Since both shift registers are identical and whose inputs are connected to the output of the same generator, it is enough for their synchronous switching that both registers are set to the zero state before starting operation. In this case, the shift register at the receiver side must be enabled first, and second at the transmitting side, and only after they are set to the zero state, it is necessary to feed pulses from the generator output 1 of clock pulses.

Дл установки в нулевое состо ние регистров 5 и 9 сдвига используютс их входы установки О, подключенные к выходам формирователей 2 и 8 импульса сброса. При подаче питающего напр жени в начальный момент времени на установочных входах регистров 5 и 9 сдвига присутствует 1 и по мере зар да конденсаторов дифференцирующих цепей на их установочных входах по вл етс О и регистры готовы к работе. Одновременно на второй вход элемента И 4 .через инвертор 3 подаетс 1, котора разре12 80422 2To set the shift registers 5 and 9 to zero, their inputs, O, are connected to the outputs of the formers 2 and 8 of the reset pulse. When the supply voltage is applied at the initial moment of time, 1 is present at the installation inputs of the shift registers 5 and 9, and as the capacitors of the differentiating circuits charge, the installation inputs O appear and the registers are ready for operation. At the same time, the second input of the AND 4 element. Through the inverter 3 is fed 1, which is allowed to 80 8022 2

шает прохождение импульсов с генератора 1 тактовых импульсов на входы регистров 5 и 9 сдвига.This implies the passage of pulses from the generator of 1 clock pulses to the inputs of registers 5 and 9 of the shift.

Дл предотвращени взаимного закорачивани выходов регистра 5 сдвига введены в цепь каждого выхода элементы 6 потенциальной разв зки.In order to prevent mutually shorting of the outputs of the shift register 5, the elements of the potential isolation are introduced into the circuit of each output.

С момента включени устройства генератор 1 тактовых импульсов начинает вырабатывать импульсы, которые поступают на вход регистра 5 сдвига и через первый провод линии св зи 11 на вход регистра 9 сдвига. Эти импульсы формируют в пор дке очередности импульс на каждом из выходов регистров 5 и 9 сдвига.From the moment the device is turned on, the clock pulse generator 1 begins to generate pulses that arrive at the input of the shift register 5 and through the first wire of the communication line 11 to the input of the shift register 9. These pulses form, in order of priority, a pulse at each of the outputs of shift registers 5 and 9.

С выходов регистра 5 импульсы сдвига поочередно подаютс на соответствующие выходам замыкающие ключи 7, а с выходов регистра 9 сдвига поочередно подаютс на вторые входы элементов И 10, однако, так как состо ние замыкающих ключей 7 нормально разомкнутое, на первые входы элементов И 10 импульсы не поступают , управл ющие сигналы на выходахFrom the outputs of register 5, the shift pulses are alternately fed to the corresponding outputs of the closing keys 7, and from the outputs of the register 9 of the shift alternately fed to the second inputs of the And 10 elements, however, since the state of the closing keys 7 is normally open, to the first inputs of the elements of And 10 the pulses are not control signals are output

Дл того, чтобы передать какую-ли- либо команду, необходимо замкнуть соответствук ций замыкающий ключ 7,In order to transmit any command, it is necessary to close the closing key 7,

тогда на оба входа соответствующих элементов И 10 одновременно придут импульсы с регистров 5 и 9 сдвига и элемент И 10 изменит свое состо ние . При необходимости передать команды , соответствующие каждому второму и п тому импульсу, необхйдимо замкнуть второй и п тый замыкающие - ключи 7, затем одновременно с каждым последующим вторым и п тым импульсом генератора 1 тактовых импульсов будут по вл тьс импульсы и в первом проводе св зи 11, т.е. на вторых входах всех элементов И 10 и на первых входах второго и п тогоthen both inputs of the corresponding And 10 elements will simultaneously receive impulses from shift registers 5 and 9 and the And 10 element will change its state. If it is necessary to transmit commands corresponding to each second and fifth pulse, it is necessary to close the second and fifth short circuits - keys 7, then simultaneously with each subsequent second and fifth pulse of the clock generator 1, pulses will appear and in the first wire of communication 11 i.e. on the second inputs of all elements And 10 and on the first inputs of the second and n that

Compared with the prototype, the proposed device provides for the sequential (in one cycle) transmission of several (or all) commands (while the prototype can only transmit one command), except for this one, it has a simpler design and consumes less electricity.

The invention relates to systems for remote control of objects and technological processes. The purpose of the invention is to simplify and enhance the information content of the device by ensuring the sequential transmission of several commands in one cycle of operation. The drawing shows a functional diagram of the proposed device. The device contains on the transmitting side a clock pulse generator 1, a reset pulse shaper 2, an inverter 3, element 4, a shift register 5, potential breakout elements 6, closing keys 7, on the receiving side a reset pulse shaper 8, a shift register 9, elements And 10, the first and second wires of the communication line 11, -117 of the driver 2 and 8 of the reset pulse are resistors 12 and 13, capacitors 14 and 15. The proposed device works as follows. To operate the device, it is necessary to synchronously switch the shift registers 5 and 9 at the receiving and transmitting sides, i.e. at any time, the unit must be written in the same bits of both registers. Since both shift registers are identical and whose inputs are connected to the output of the same generator, it is enough for their synchronous switching that both registers are set to the zero state before starting operation. In this case, the shift register at the receiving station must be turned on first, and on the transmitting side second, and only after they are set to the zero state, it is necessary to feed pulses from the generator output 1 of clock pulses. To set the shift registers 5 and 9 to zero, their inputs, O, are connected to the outputs of the formers 2 and 8 of the reset pulse. When the supply voltage is applied at the initial moment of time, 1 is present at the installation inputs of the shift registers 5 and 9, and as the capacitors of the differentiating circuits charge, the installation inputs O appear and the registers are ready for operation. At the same time, the second input of the AND 4 element. Through the inverter 3 is fed 1, which permits the passage of pulses from the generator 1 of clock pulses to the inputs of the shift registers 5 and 9. In order to prevent mutually shorting of the outputs of the shift register 5, the elements of the potential isolation are introduced into the circuit of each output. From the moment the device is turned on, the clock pulse generator 1 begins to generate pulses that arrive at the input of the shift register 5 and through the first wire of the communication line 11 to the input of the shift register 9. These pulses form, in order of priority, a pulse at each of the outputs of shift registers 5 and 9. From the outputs of register 5, the shift pulses are alternately fed to the corresponding outputs of the closing keys 7, and from the outputs of the register 9 of the shift alternately fed to the second inputs of the And 10 elements, however, since the state of the closing keys 7 is normally open, to the first inputs of the elements of And 10 the pulses are not there are no control signals at the outputs of the device. In order to transmit any command, it is necessary to close the closing key 7, corresponding to the closing key 7, then both inputs of the corresponding AND 10 elements will simultaneously receive pulses from the shift registers 5 and 9 and the AND 10 element will change its state. If it is necessary to transmit commands corresponding to each second and fifth pulse, it is necessary to close the second and fifth closing keys 7, then simultaneously with each subsequent second and fifth pulse of the clock generator 1, pulses will appear and in the first wire of communication 11, those. at the second inputs of all elements And 10 and at the first inputs of the second and fifth elements And 10, i.e. they change their state. These elements And will be triggered throughout the entire closure of the locking keys 7. Since the pulse frequency from the clock generator 1, and hence the frequency of polling cycles of the shift registers for practical pulses, is high enough, we can assume that the transmission n commands occur simultaneously; So, with a pulse generator frequency of 1 MHz, the duration of the polling cycle will be equal to only 0.016 μs. Compared with the prototype, the proposed device provides for the sequential (in one cycle) transmission of several (or all) commands (while the prototype can only transmit one command), besides that, it has a simpler design and consumes less electricity. The ability of the proposed device to simultaneously transmit several commands simultaneously (in one cycle) increases the efficiency of managing objects and technological processes; the simplicity of the design makes it possible to significantly reduce the mass and dimensions of the device.
