FAIL-SAFE CONTROL SYSTEM Russian patent published in 2021 - IPC G06F11/16 

FIELD: computing.

SUBSTANCE: invention relates to the field of computing, in particular to methods for constructing highly reliable computing control systems by duplicating information, and devices designed to receive and process information and issue the resulting signals to the control object. The fail-safe control system contains the main and backup control modules based on processors, majority elements, signal output modules and a synchronization unit. The main and backup control modules are united by a common input and output data bus. The output data bus is configured to transmit signals from each of the control modules to all majority elements simultaneously. Error control units for each of the control modules and signal output modules are connected to the outputs of the majority elements, error indication units are connected to the outputs of the error control units to output information about the failed control channel.

EFFECT: reliability and efficiency of the control system is increased.
