CONTROL DEVICE Russian patent published in 2019 - IPC G05B23/02 G05B21/02 G01R19/255 

FIELD: electricity.

SUBSTANCE: invention relates to the field of testing electrical systems. Control device contains a pulse generator, the output of which is connected to the input of the pulse counter, the outputs of which are connected to the input of the indicator. Outputs of the control object are connected to the inputs of a multichannel analog-to-digital converter and to the inputs of a matching device, the outputs of which are connected to the inputs of a multiplexer, the output of which is connected to the input of the EXCLUSIVE OR logical gate. Output of the EXCLUSIVE OR unit is connected to the control input of the pulse counter, the output of which is connected to the input of the short pulse shaper, the output of which is connected to the reset input of the time relay, the output of which is connected to the second input of the EXCLUSIVE OR logical gate. Output of the multichannel analog-digital converter is connected to the microcontroller, which is connected to the memory unit, the counter, the output of the EXCLUSIVE OR gate and to the personal computer. Output of the pulse counter is connected to the input of the multiplexer and the input of the microcontroller.

EFFECT: ability to determine the sequence number of the channel of the multichannel power source on which the fault occurred and to save information about the nature of the change in the output voltage.
