Description

The invention relates to the field of automation and information transfer in automated control systems and can be used to control dispersed objects.

The purpose of the invention is the expansion of the functionality of the device by providing control over the feedback channel. 10

The drawing shows a functional diagram of the device.

The device contains a control point 1, code buses 2-5, relays 6-17, relay contacts 6, 6 ^ -17 ^, 17 ^, information sources 6¾-17e, diodes ⁰ 18-29, zener diodes 30-41, respectively forming control cells of the first and second groups, at the control point, terminal 42 of the positive potential and 20 terminal 43 of the negative potential of the power source, the first 44 and second 45 groups of control keys, information receiving unit 46.

The device operates as follows 25.

A control command for the first control cell of the second group is sent when the corresponding keys are turned on in the first and second group of singing control keys-30. A circuit is formed: plus a source from terminal 42, a closed key of the second group, code bus 2, a communication line, a diode 24, a zener diode 36, relay 12, code bus 3, a communication line, code 35 bus-3, a closed key of the first group, terminal 43 to the minus of the source. The relay 12 of the inclusion of the object is activated.

At the control point, the information receiving unit 46 by the method of eliminating locked 40 keys determines free code buses and connects the information receiver circuits to them. At the controlled point, the D5 source of information is connected to call-free code lines 4 and 5 via contacts 12.1 and 12.2 of the activated relay 12. Thus, a reverse communication channel is organized for transmitting information from the controlled point. After accepting the necessary ING0 information from the controlled point, it is turned off by opening the keys of the first and E ^ second groups and turning off the relay, which disconnects with its contacts. sourse of information. 55

By combining the corresponding code buses and the polarity of the power supply, a control command can be sent to the corresponding control unit of the corresponding controlled point.

The zener diode is introduced in order to exclude the operation of the control cell from the voltage of the information source. Connected to the same · corresponding code buses. The voltage of the information source is selected less than the threshold voltage of the zener diode of the controlled item. The voltage of the power supply of the control commands is taken to be greater than the voltage of the information source. Due to the difference in the amplitudes of the voltage of the control commands and information from the monitored points, it is possible to simultaneously control and control objects.
