RELAY CONTROL Russian patent published in 2011 - IPC G05B11/26 

FIELD: physics.

SUBSTANCE: relay control has in each of (2m+1) channels an analogue-to-digital converter (ADC), a memory device, a digital comparator, a pulse generator, a pulse counter, a flip flop, a multiplexer, first and second majority decision elements, a univibrator, an inverter, first, second, third and fourth OR elements, first, second and third AND elements, first and second XOR elements. Given duration τ_d and pause t_p parameters of the control signal as a function of the input signal are recorded in the memory device and owing to continuous comparison of actual values with given values, the relay control does not cause delays in the control system and non-faulty operation of the relay during faults in m channels of the control and given operation, corresponding to generation of a control signal in accordance with variation of the average-value from all input signals, is ensured owing to certain connections.

EFFECT: high reliability and noise-immunity of the relay control.
