SYSTEM FOR REMOTE CONTROL OF CONTROLLED OBJECT Russian patent published in 1994 - IPC

FIELD: remote control devices. SUBSTANCE: signal from one of N receivers 3 at first or second controlled object 1 or 2 effects objects final-control devices 10 through first multichannel commutator 4 and decoder 5. Signal of set-point 16 is transmitted to another controlled object through encoder 14, second multichannel commutator 8 and one of N transmitters 9. When receiver faults or radio link is noisy, AND gate 20, first delay gate 11 and second delay gate 16 perform lock of output signals of decoding circuit 19 and switch first controlled oscillator 12 and first pulse counter 13 on. This pulse counter connects operating receiver through commutator 4 and generates signal about fault. Signal for lock of output signals switches second controlled oscillator 6 and second pulse counter 7 which connects operating transmitter through second commutator 8. EFFECT: increased field of application, improved fault detection and increased reliability. 1 dwg
