The purpose of the invention is to increase the reliability of the control.

The system consists of two identical control devices: the main and auxiliary.

Each of the pulse formers 26, 31, 34, 37 and 40 (Fig, 2) consists of the twelfth element And 43, the third pulse counter 44 and the sixth trigger 4.5,

The control signal combining unit 18 is a diode unit with output coupling, and the control signal branching unit 19 is a diode power supply unit with combining at the output.

The installation verification system uses DP verification and labeling of multiconductor cables, with cables with ends distant from each other at a considerable distance, preventing the test cable from being connected to one device. Two similar devices are used to check the cable data, one of which is connected to one end of the cable and goes into auxiliary mode, and the other is connected to the other end of the cable and goes into main mode.

The elements of the main device are labeled with the index 1 auxiliary - the index

The system works as follows.

After the main and auxiliary devices are turned on, the initial state button, located in block 35, setting the initial state of the main device, sets the trigger 32, the initial state to 1. Then, using the switch 42, the mode settings start the shaper 40 of the synchronization pulses by the output signal which are simultaneously launched by the formers 26., and 26 polling pulses of the initial state of both devices, the synchronization pulse being simultaneously fed to the inputs of the signal combining unit 182 over all connecting devices to each other, the wires of the cable being tested.

then the outputs of the 1C interface unit with the control object and the inputs of the signal combining unit 18 /, through the OR element 24, and the signal branching unit 19, from the output of the And 28 element, receive a signal of the initial state, which is allocated by the signal combining units 18 and 18 of both devices and arrives at the inputs of the elements And 25, 25. From their outputs, the signal of the initial state sets the counters and triggers of both devices to the initial state. The signal from the outputs of the formers 26 and 26 of the initial state polling pulses triggers the formers 31 and 32 of the unpowered polling pulses and switching cycle triggers 27, 27, which block the trigger inputs of the formers of the initial state from the extraordinary start. In the main device, from the output of the interrogation pulse imaging unit 31, the impulse is fed to the gate input element I 29, the second input of which

at this time, the NOT 30 element passes through the conductors of the cable under test a pulse from the output to the generator 312 of the interrogation pulses for the absence of communication of the auxiliary device. If this impulse does not come, the AND element 29 generates a signal of the absence of communication, which turns on the trigger 23 of the fixation of the absence of communication, and it generates an indication. In this case, it is necessary to stop the breakout process and check the correctness of the connection of the tested cable to the devices.

If the cable is connected correctly (i.e., the tested cable is connected to the main and auxiliary devices, it is connected from the main device to the first group of outputs of the decoder 7, the group corresponding to the main device, and from the auxiliary device to the second group outputs of the decoder 7., the group corresponding to the auxiliary device), then the next operation after checking the presence of the communication channel between the devices will be a dialing operation

It is executed by a strobe pulse generated by a shaper 34 (and 34 strobe pulses. The strobe pulses in both devices initiate the counter code 5 ;, and 5 one of the decoder buses 10 and 10, which connects to the output of the AND-OR elements 17 / 17, j, the input corresponding to this bus, connected to the output of the decoder 7 and 7 of the main and auxiliary devices. Similarly, the output buses corresponding to the counter code 6; and 6, rf, decoders 7 and 7 at the beginning of the first group of outputs are excited by strobe pulses. and then the second The voltage of the excited bus of the first group is fed to the input of the 1C block interface with the test object and to the input of the element AND-OR 17u with a number corresponding to the counter code 6. ;, ,, or to any other input (inputs) through the connections of the tested product, as well as through the conductor of the cable being tested, if it is connected to this bus, enters the input of the auxiliary device element AND-OR 17. If there is a voltage for continuity at the output of the AND-OR elements 17 and 17 and the contents of counters 6 and 6j are less than counters 5 and 5, the elements And 13 and 13 produce It is a signal which changes the state of the counter 6 and 6 to 1. This corresponds to what has been discovered compound and it is not necessary to again fix. The equality of the contents of the counters 6 and 5 is used to monitor the health of the device switches. This is achieved by the fact that when the codes in these counters are equal, the decoder 7 and 7 are excited and the same bus is polled in I-SHIII 17. and 172 (i.e., if the counter codes are equal, the presence of elements I-IPI G7 and 17 signal of the presence of a connection) And if the signal of the presence of a connection when the contents of the counters 5 and 6 are equal, is missing, elements 15 and 15 produce a signal that triggers output control units 3 and 3 and includes triggers 39 and 39. The output unit captures the address of the faulty bus with a corresponding comment. The occurrence of the signal of the presence of a connection at the output of the elements AND-OR 17 and 17, provided that the contents of counter 6 more than counter 5 corresponds to the detection of a connection not previously fixed, and therefore elements 21 and 21 make a signal that triggers blocks 3 and 3, output control and includes flip-flop triggers 39 and 39. If the voltage of the excited bus of the decoder 7 through the core of the cable being tested or directly from the output of the decoder 7 arrives at the output of the I-17 element of the auxiliary device and there is no condition (the contents of the counter 6 are less than the contents of the counter 5), it is fixed by the connection fixing trigger 39j. The interrogation signal from the output of the formers 37, and 37j of the interrogation pulses triggered by the strobe signal, prepares the beginning of the next test cycle by activating the cycle triggers 27 and 27 in the auxiliary device, polls the element 38, to the second input of which the information comes from the main device polls the element I 36, to the second input of which from the output of the element 38 of the auxiliary device, via a cable to be checked, during the action of the interrogation signal comes a signal of the presence of a connection if it was fixed IAOD during the previous action signal strobe trigger 39 fixing compound, and the output of AND sheetogo control unit 36 starts the output of the main unit.
