SU675426A1 - Electric wiring testing device - Google Patents

Description

It contains the control unit 1, the address register 2, the decoder 3, the shaper 4 signals, the comparison circuit 5, the encoder 6, including transformers 7, the read amplifiers 8 and the code register 9, and the control object 10.

The device works as follows.

According to KOMaliMe, from node 1 of the controller in register 2, the corresponding addresses are set, which are fed to decoder 3. The selected decoder bus triggers the signal conditioner 4, which sequentially excites the circuits of the object 10.

Since the device has a chain of sequential 6 yoYoMs with coding leads of the encoder 6, tbPs with; btatstugugbybi1M; the wires are flowing, the output signals of the transformers through the amplifiers 8 are fed to the input of the output register 9, and from its outputs to the inputs of the comparison circuit 5. Scheme lmT ffi®Mrf Tr MeShё - flowed through the encoder and the readable circuit and the read information, which is received from the encoder 6. If the address codes and the number code are dropped, which indicates the good condition of the circuits, the following address. If any of the M checked circuits is cut off, the expected signals are not received to circuit 5 from the information register, and a stop occurs indicating the address of the broken circuit. If there is a short-circuit between the circuits, also, refer to the Outline of the Clone de oTono1) T can remove the code, since the signals from shaper 4 are then fed to: several cords of coding wires. In this case, the output information becomes the same for the closing circuits and the device stops. In this case, the addresses of the faulty circuits are also recorded during their sequential polling. First of all, the windings of transformers 7 are connected according to the binary code of through-numbered check circuits and this provides a shortcut

The number of transformers to the number equal to the binary logarithm of M.

Thus, the device allows, with a reduced amount of equipment, to carry out an assembly check. .
