BENCH FOR DIAGNOSTICS OF MICROPROCESSOR SYSTEM OF LOCOMOTIVE CONTROL Russian patent published in 2013 - IPC G05B23/00 

FIELD: electricity.

SUBSTANCE: bench is proposed for diagnostics of a microprocessor control system (MCS) of a locomotive, which comprises a computer, a source of power supply. The bench is equipped with a control unit, a unit of digital-to-analogue converter (DAC) switchboards, a unit of frequency signals inspection, a unit of input discrete channels inspection, a unit of output discrete channels inspection, a unit of MCS width-pulse modulators inspection and a unit of loads, besides, the computer is connected with the diagnosed MCS, the control unit is connected with the unit of DAC switchboards, the unit of frequency signals inspection, the unit of input discrete channels inspection, the unit of output discrete channels inspection, a unit of width-pulse modulators inspection, at the same time outputs of the DCA switchboards unit are connected to the MCS inputs, outputs of the frequency channels inspection unit are connected with the MCS inputs, outputs of the input discrete channels inspection unit are connected with MCS inputs, the inputs of the output discrete channels inspection unit are connected with MCS outputs, WPM-inputs of the width-pulse modulators inspection unit are connected with outputs of the MCS WPM and with the input of the loads unit, the control unit is connected along the second serial channel of communication with MCS, the source of power supply is connected with the diagnosed MCS and with all units of the bench, apart from the loads unit.

EFFECT: simplified bench design and increased reliability of its operation.
