Description

Time delay 23, 24 and transmitters 25, 26.

When the device operates in the telecontrol reception mode, the frequency-modulated signals are transmitted on the communication lines to the receiver 1, which converts them into a series of unipolar pulses. From receiver 1, pulses are sent to the line unit 2, which controls the operation of the counter 3 and the control unit 6. The control unit 6 enables the decoder TU 7 to work and prohibits the operation of the TC decoders 8 and 9. In this case, the executive relay unit 11, and the transmitters TC 25, 26 remain in the locked state. The selection of incoming pulses by duration is performed as follows; at the leading edge of each pulse, the linear unit 2 excites time relays 4 and 5, time relays 4 are set for the time of the long impulses, and time relays 5 for the time of the extra long impulses. Timer 4 output signal blocks the counter. In this case, the output signals of time relay 4 and 5 affect the inputs of the imaging unit 10, preparing it for operation. The shaper 10 is triggered when the time relay is not synchronized or when the pulse duration is distorted. When the generator 10 is triggered, the control unit 6 prohibits the activation of the executive relays in the block 11.

When the device is in the mode of transmitting television signals, the decoder 7 is locked by the control unit 6, and the decoders 8 and 9 are unlocked. Decoders 8 and 9 affect recording units 13, 14. Recording is performed only at the end of the transmission of television signals, when the last bus of decoders 8 and 9 controls the logic elements 15 and 16, which through the magnetotransistor cascades 17 and 18 and the contacts 19 and 20 of the sensors and position t record the position of objects. As a result, interference during the transmission of television signals cannot produce a false record.

Under the influence of the decoders 8 and 9, the recording units 13 and 14 control the manipulation

transmitter (25, 26) through the logical element "AND-NOT (21, 22) connected to the blocks of the time delay 23, 24; and the output of each delay unit is connected to the diode input of the NAND element, as a result of which the duration of the frequency bursts is provided.
