REDUNDANT FOUR-CHANNEL DIGITAL CONTROL SYSTEM Russian patent published in 2018 - IPC G06F15/16 

FIELD: computer equipment.

SUBSTANCE: invention relates to the computer equipment. System contains four identical control channels, each of which contains computing device (CD), majority element (ME), error control unit (ECU), telemetry control unit (TCU), the main and backup transceivers for telemetry exchange, main and backup receivers and transmitters for data exchange between computing devices. Increase in fault tolerance is achieved due to the ability of the system to function when two channels fail, while maintaining the system's operability, as well as the presence of redundant signal exchange lines for the control signal. Increase the controllability and autonomy of the system, if one of the channels fails, is achieved due to the ability of majority information retrieval via the "2 of 3" voting scheme between the computational units and the I/O blocks of the system channels without using external equipment.

EFFECT: technical result is increased fault tolerance, maintainability and autonomy of the system.
