SU1467766A1 - Arrangement for remote monitoring of intermediate stations of communication system - Google Patents

Abstract

The invention relates to telecommunications. The purpose of the invention is to improve the accuracy of telecontrol. The device contains a shift register 3, a signal detector 4, a address decoder 5, a sync signal decoder 6, a reception register 9, a memory unit 10 and a display unit 11. In order to improve the telecontrol accuracy, at each intermediate station, 1 control signal generator, 2 address generator, operating mode selection block 7 and OR 8 element are entered. At the first terminal station, driver 2 generates a digital interrogation signal of intermediate stations, which contains a clock signal and N words, each of which consists of the address part and the time interval for recording telecontrol data at the corresponding intermediate station. If the terminating station goes out of operation, then the nearest intermediate station takes over its functions and becomes a bore. 1 hp ff, 5 ill. S

Claims (2)

Claim 1. A device for telecontrol of intermediate stations of a communication system, comprising at the transmitting terminal station a control signal generator and an address generator, at each intermediate station a signal detector whose outputs are connected to the inputs of the shift register, the first group of outputs of which is connected to the inputs of the clock decoder, and the second group of outputs is connected to the inputs of the address decoder, the output of which is connected to the input of the signal detector, and at the receiving terminal station - Well connected reception register, memory unit and display unit. characterized in that, in order to improve the accuracy of telecontrol, at each intermediate station, serially connected control signal generator, an operating mode ejection unit, an address shaper and an OR element, the output of which is connected to an additional input of the shift register, are introduced, while the second input of the OR element is an input the signal from the communication line from the previous station, the output of the clock decoder is connected to the second input of the operation mode selection unit, and the additional output of the shift register is the input of the communication line to the next station. 2. The device according to π. 1, characterized in that the operation mode selection unit contains the first and second AND elements, the first inputs of which are combined and are the first input of the operation mode selection unit, the second input of which is the first valve input, the output of which is connected to the first trigger input and the first counter input, the output of which is connected to the second input of the trigger, and the second input is connected to the output of the second element And, the second input of which is connected to the first output of the trigger, the second output of which is connected to the control input of the valve and the second input of the first element And, the output of which is the output of the unit, and the third input of the counter is the input of setting the account coefficient, and the first input is the input of setting the device into the intermediate station mode. fse. 3 Word of the first intermediate station The word of the last (n-th) intermediate station.
