UNIFIED LOGIC CONTROLLER Russian patent published in 2019 - IPC B61L23/00 G06F11/30 

FIELD: railway automatics.

SUBSTANCE: invention relates to railway automatics for transportation control. Controller comprises two (A, B) microprocessor computers, upper level interfaces CAN1A and CAN1B connected to CAN network drivers, lower level interfaces CAN2A and CAN2B connected to CAN network drivers, four universal asynchronous receiver-transmitter, connected to corresponding of four RS-422 serial interface drivers, two serial interfaces SPI 1,2, two serial interfaces SPI 3, safe asynchronous comparison circuit (SACC). Diversified software is loaded into microprocessor computers (A, B), wherein program code for microprocessor calculator A differs from code for microprocessor calculator B. SACC serves as arbitrator and provides comparison of results of operation of microprocessor calculators A and B on control points and enables operation of RS-422 serial interface drivers and CAN-network drivers of lower level interfaces in case of coincidence of calculation results.

EFFECT: increase in safety and reliability of work is achieved.
