Description

The invention relates to systems for transmitting electrical signals and can be used in telemechanics and automation systems,

The purpose of the invention is to increase the information content of the device.

Pa drawing presents a functional diagram of the device.

The device contains point 1 of the control unit Lenin, which consists of block 2 of command input, encoder 3, IGO 4 element, first 5 and second 6 memory registers, counter 7, decoder 8, switch 9, first 10 and second 11 indicators of block 12 display information, the element And 13, the object 14 of the control, which consists of a decoder 15 and Executive elements J6, as well as the line 17 of the connection.

The device works as follows.

The command to execute a particular executive element is given by typing the command code using the buttons of the command input block 2 at point 1 of the control. In the initial state, the first 5 and second 6 memory registers and the counter 7 are in the zero state, the initial state is determined by the digital indicators 10 and 11 of the information display unit. When dialing the first digit at the outputs of the decoder 3, a binary-decimal code appears, and at the output of the OR 4 element there is a single signal that connects to the counting input of counter 7 and to the gate input of the decoder 8 If there is a code 00 at the outputs of the counter 7 and gates The signal at the gate input of the decoder at its second output generates an enable signal for writing to the first register 5 of the memory and the code of the first digit is written to the first register.

When the button is released in block 2 of command input, a single signal at the input of counter 7 disappears and the code O sets on it with a slice, Counter 7 triggers on the falling edge of the signal and code 01 is set at its outputs.

Similarly, when dialing the second digit, the code is written into the second code.

 or

and when a signal appears on

The gate input of the decoder at its third output generates a enable signal for recording in the 15th memory register. When you release the button, the counter is activated. 7 and sets the code 10 at its outputs. The digital indicators 1O and 1 of the information display unit 12 control whether the first two digits of the code that are the command address are correct.

If the address code is typed correctly, the third digit is dialed, which is fixed, for example, O. The signal from the output of the command input block 2 is sent to the second input of the AND element and through the IDN element to the gate input of the decoder, the information inputs of which contain the code 10. The decoder 8 generates a signal at the first output, which is fed to the first input of the AND element, at the output of which a control signal is generated for the switch 9, as a result of which the information recorded in the first 5 and second 6 memory registers supplies With a parallel code on the link 1 7 to the inputs of the decoder 15 of the control object and the corresponding actuator is activated for the time the actuator digit is pressed. When the button is released, counter 7 is triggered and code I is set at its outputs. To bring the device to. the initial state is necessary to press any digit, and the appearance of the signal at the gate input of the decoder 8, if code II is present on its information inputs, generates a signal at the fourth output of the decoder, which sets registers 5 and 6 and the counter 7 to the zero state, as indicated by digital indicators 10 and P block. 12 display information.

If the address code, the command is dialed incorrectly, then the device can be reset to its original state by double dialing any other digit, besides the executive one. In this case, the transfer of information to the object 14 control does not occur.

Thus, having control buttons in the command input unit, 99 actuators can be controlled. This reduces the number of connecting wires between the control point and the control object.
