Description

one

This invention relates to a remote sensing technique.

A device for displaying communication channel states is known, comprising serially connected input amplifiers, an intermediate register, a starting pulse generator with an input distributor, the second input of which is connected to a generator, as well as counters of durations of current interruptions with indicators, a code converter, an output periodicity counter with a clock generator. pulses connected to an output distributor, a stop pulse shaper, and a coincidence circuit.

However, the known device does not solve the task of simultaneously simultaneously displaying all currently faulty Ciaals.

The purpose of the invention is to accelerate the indication of faulty channels. For this purpose, equally accessible registers of memory numbers of irregular channels, causes and durations of their failures with indicators, input and output key schemes are entered into the device. The outputs of the intermediate register are connected to the first inputs of the input key circuits, the second inputs of which are connected to the corresponding outputs of the input distributor via the matching circuit of the intermediate and equally accessible registers. The output of one of the coincidence circuits is connected to a stop pulse shaper connected to the stop input of the input distributor. Outputs of equally accessible memory registers

connected to the code converter via output key circuits, each of which inputs are connected to the corresponding output of the output distributor.

The drawing shows a diagram of the device

to display the state of the communication channels.

The device contains serially connected input amplifiers 1, straightened; weft register 2, driver for starting pulse 3 with input distributor 4, the second

the input of which is connected to the generator 5, as well as the counter of the durations of the current interruptions 6 with the indicator 7 and the coincidence circuit 8, the code converter 9, the output periodicity counter 10 with the clock pulse generator 11 connected to the output distributor 12, the stop pulse generator 13, readable registers 14, 15, 16 memories of numbers of faulty channels, causes and durations of their failures with indicators

17 and 18, input 19 and output 20 key schemes.

The outputs of the intermediate register 2 are connected to the first inputs of the input key circuits 19, the second inputs of which are connected to

corresponding distributor outputs

but

input 4 through the matching schemes 21-22 of intermediate 2 and equally accessible 14, 15 registers. The outputs of equally accessible registers 14, 15, 16 are connected via a matching circuit 23 and 24 to a stop pulse shaper 13 connected to the stop input of the input distributor. In addition, the outputs of registers 14 and 15 are connected to a code converter 9 through output key circuits 20, each of whose inputs are connected to the corresponding output of the output distributor 12, and the output of the distributor 4 is connected to the input of the register 16 via matching circuits 25 and 26.

The device works in the following way.

The code combinations of pulses affecting the input of the device, carrying information about the numbers of faulty communication channels and the reasons for their failures, go through input amplifiers 1 to intermediate register 2. The input distributor 4 is started by changing the state of the intermediate register by shaper 3, the clock pulses of which are supplied from the generator 5. With simultaneous receipt of signals from the input distributor and the register of causes of failures 15, when it is free, the output signal through the circuit 21 enters the coincidence circuit 22 the current key circuit 19, which ensures the rewriting of the code combination from the intermediate register into equally accessible registers 14, 15. Simultaneously through the coincidence circuit 8, the counter of the durations of the current interruptions 6 is started. On indicators 7, 17, 18 the number of the faulty communication channel is displayed, the cause of the failure and the duration of the failure time. When the progenitor 2 state and the equally accessible 14 and 15 registers coincide, the stop pulse shaper 13 is started from the output of the matching circuit 23, which prohibits the transfer of "unit to distributor input 4. Writing off" the unit in the input distributor eliminates the use of the next available equally accessible register by the received code combination.

Upon receipt of a code combination on the input of the device by another communication channel, the circuit operates in the same way, ensuring that the combination is stored and displayed on the free equally accessible register 16. Overwriting the code combination into register 16 is provided by the operation of the matching schemes 24, 25, 26. In the case of receiving the code combination about the restoration of the communication channel, the signal from the output of the corresponding coincidence circuit permits rewriting of this combination to the register in which the failure of the given communication channel was recorded. In this case, the signal "norm from the output of the register of causes of failures translates this equally accessible register to the" zero state and turns off its indicators.

The output of information about the failure of the communication channels to the documenting device is carried out by affecting the output periodicity counter 10 on the clock generator 11 of the output distributor 12. Signals with the output of the output distributor are fed to the output key circuits 20, allowing the output of information from the equally accessible registers 14 and 15 to code converter 9, to which the documenting device is connected.
