The invention relates to telemechanics and can be used to monitor the state of dispersed objects.

The purpose of the invention is to increase the reliability and the device by controlling the operating modes of the communication line and simplifying the controlled points.

FIG. 1 is a functional diagram of the device control station; in fig. 2-functional scheme of the controlled item; in fig. 3 is a schematic of the layout of the control key and the code disk contained therein, which generally represent the information input of the device.

The device contains item 1 of control, first 2i and second 22 communication wires and controlled items 3i - 3 m.

Control point 1 contains a generator of 4 clock pulses, a frequency divider 5, a valve 6, an element OR 7, a bipolar pulse generator 8, a receiver 9, a positive pulse selector 10, a negative pulse selector 11, an indicator block 12.

The controlled item contains a frequency doubler 13, a rectifier 14, a clock selector 15, a distributor 16, a control key 17.

The device works as follows.

At the control point, the pulses of the generator 4 clock pulses are divided by the frequency of following in half in block 5 and through the OR element are fed to the shaper 8 of a bipolar pulse, the output of which is fed to the input of the second wire of the 1st link. In addition, the pulses of block 4 are fed to the input of the distributor bis of the outputs of the first group of this distributor through blocks 7 and 8 also arrive at the input of the second wire 22 of the communication line, forming a clock signal. From the output of the first wire 2i

the communication links to the input of the receiver 9 are pulses, which are separated by the selectors 10 and 11, respectively, of positive and negative pulses. These pulses are sent to the block 12 indicators synchronization corresponding pulses from the outputs of the second group of the distributor 6.

At the controlled point, bipolar pulses are sent to the frequency doubler 13 and from the output of the frequency doubler to the input

rectifier 14, to the input of the selector 15 of the sync signal and to the clock input of the distributor 16, to the synchronization input of which pulses are received from the output of the selector 15 of the sync signals. The outputs of the distributor 16 in pairs correspond to the number of the controlled item.

As the control key 17, two optocouplers are used and a code disk, the position of which corresponds to the signal information. One half of the code disk is transparent, and the other is opaque (Fig. 3A), or one half of the code disk reflects, and the other one absorbs the radiation from the optocoupler LED. When managers

the signals are successively in vs on the two outputs of the distributor 16 in the time intervals corresponding to the number of the controlled point, the wires 2h and 2a are closed with a key (the photo thyristor of an opto-couple)

to one of these time intervals, at which the light flux passes through the transmission part of the code disk, the position of which corresponds to the transmitted signal information. In this case, the voltage from the output of the bipolar pulse generator 8 is transmitted to the input of the control point receiver 9. Depending on the location in time of the received pulses, a short circuit, wire break of the communication line, information units and zero are indicated. This ensures continuous monitoring of the operating modes of the controlled points and the communication line, which increases the reliability of the device and simplifies the controlled points.
