Abstract

The invention relates to a technique for transmitting discrete messages and is intended to control the equipment of the transmission and reception path for discrete messages. The purpose of the invention is to increase the reliability and performance of the device by ensuring that the main part of the equipment can continue to operate in the presence of a fault signal. To achieve this goal, the second switching unit, the second switching unit, the first and second comparison units, the first distributor and the memory unit, are entered into the device containing the first switch unit, encoder, transmission unit, decoder, receive unit, code control unit, chronizer, the second distributor, the radio pulse shaper, the OR element and the command pulse shaper. The device operates either in the main operation mode or in the control mode - after the appearance at the output of the control unit of the error signal code. In the control mode, the device operates in two cycles - in the test cycle of the transmission unit and the reception unit and in the path test cycle as a whole, with distortion of the control pulses in the transmission unit, reception unit and in the path as a whole. Information signals, pilot pulses, fault signals at the outputs of the transmission unit, the reception unit and the comparison units, as well as matching source and output pulses, when checking the path through the first and second distributors, go to the memory unit, from where they are read by external commands at the allowed time and through the driver of radio pulses are fed to an external recording device. 1 il.

Description

The invention relates to a technique for transmitting discrete-: messages and is intended to control the equipment of the transmission and reception path of discrete signals.

The purpose of the invention is to improve the reliability and performance of the device by enabling

the continuation of the work of the main part of the equipment in the presence of a fault signal.

The drawing shows the functional diagram of the device.

The device contains a porrch switching unit 1, a coder, a block, a transmission i, the second block 4 transfer lm, deco3156

der-5, receiving unit 6, code control 7, chronizer 8, control pulse generator 9, first comparison unit 10, second comparison unit 11, first distributor 12, memory block 13, second distributor 14, radio pulse shaper 15, OR element 16, the driver 17 command pulses.

The device works as follows.

External information signals and signals from the output of the imaging unit 9 control pulses, which respectively in the main operation mode and the control mode are fed to the input of the encoder 2, are fed to the inputs of the first switching unit 1. The input signals are switched by the unit 1 according to the signal from the output of the unit 7 code control in the appearance in the code at the output of the decoder 5 errors. The signals from the output of the encoder 2 through the transmission unit 3 and the switching unit 4 are fed to the input of the communication channel and from the output of the communication channel through the switching unit 4, the decoder 5 and the receiving unit 6 to the output of the device.

The control of the service is carried out in two cycles.

In the first cycle, the control pulses from the output of transmission block 3 through the second switching unit 4 are fed to the input of decoder 5 directly and in the second cycle, the control pulses are fed from the output of transmission block 3 to the input of the communication channel and from the output of the communication channel to the input of the decoder . In the first cycle, the signals at the output of the 3 reduction unit and the receiving unit 6 are compared with the initial signals of formation of 9 control pulses, respectively, in blocks 10 and 11 of the comparison, and in the second cycle the signals that pass the entire path and the initial signals of the imager of 9 control pulses are compared

Information signals and pilot pulses with the output of the transmission unit 3 and the reception unit 6, malfunction signals from the outputs of the comparison units 10 and 11, matching source and output control pulses through the distributors 12 and 14 enter the charger, from where they are read by external control commands . To interface the storage device with external recording radio devices, a shaper of 15 radio pulses was used, and to indicate the readability of the operator
