DEVICE FOR OBJECT CONTROL Russian patent published in 1997 - IPC

FIELD: automatic control equipment. SUBSTANCE: signals from n parameter detectors and m detectors of parameter alternation speed are sent through first and second multiplexers to first and second gates which outputs serve as first and second outputs of device. When faults of detectors occur, generator of control signal, comparison unit and threshold gate generate signal which renders first and second gates non-conducting through first and second AND gates, delay gate and flip-flop. This results in possibility to lock false signals. EFFECT: increased functional reliability. 1 dwg
