Description

one

The invention relates to radio and can be used in digital transmission systems with pulse code modulation and time division.

A device for remote control of linear regenerators is known, which contains a transmitter of control signals at the terminal station, and at each intermediate station a detector, the input of which is connected to the first output of the regenerator of the transmitting path, and a switching unit connected between the second output of the regenerator of the transmitting path and the input of the regenerator of the receiving path 1 .

However, the known device is characterized by the complexity of the equipment containing a large number of low-frequency generators at the terminal station.

In order to simplify the device for remote control of linear regenerators by eliminating low-frequency generators in it, serially connected pulse interrupter and element I are inputted to the terminal station, to the second input of which (the transmitter output of control signals is connected, and serially connected counter and determiner connected to each intermediate station, while the counter input is connected to the detector output, and the output

The deschiprator is connected to the auxiliary input of the switching unit.

The drawing shows a block diagram of the device.

The device contains at the terminal station 1 transmitter 2 control signals, and at each intermediate station 3 - detector 4, regenerator 5 of the transmitting path, switching unit 6, regenerator 7 of the receiving path, and also at the terminal station 1 serially connected pulse interrupter 8 and element 14 9 , to the second input of which is connected the transmitter output 2 control signals, and at each intermediate station 3 - serially connected counter 10 and decipheror 11, while the input of counter 10 is connected to the output of the detector 4, and output de ifratora 11 is connected to an additional input switching unit 6.

The device works as follows.

A control signal is sent to one of the inputs of element 9 from the output of transmitter 2, and a signal from the output of pulse interrupter 8 to the other input.

At the output of the element And 9 are formed the pulse of the pilot signal, arriving at the input of the linear path of the transmission system. The duration of bursts of pulses and interpals between npmi is determined by the time

switching on and off the immersion chopper 8. Received at the output of the terminal station 1 packet of impulses of the control sigal carry information about the number of a pair of regenerators 7 to be monitored; Combinations of the number of transmitted bursts of pulses correspond to the number of a pair of checked regenerators 7. At an intermediate station, 3 bursts of pulses from the output of the regenerator 5 receive an input to detector 4, and to the output of which combinations of pulses are formed with time parameters corresponding to the time parameters of the pulses of an pulsed interrupter 8.

From the detector output 4, the pulses go to the input of the counter 10, and from the latter’s output to the input of the decoder 11, the output of which is connected to the input of the switching unit 6. The switching unit 6 operates and connects the output of the regenerator 5 to the input of the regenerator 7.
