DEVICE FOR REMOTE CONTROL Russian patent published in 1999 - IPC

FIELD: information transmission equipment. SUBSTANCE: device has transmitter and receiver, which are connected by means of communication line. Transmitter is designed as decoder and AND gates. Receiver is designed as decoder, AND gates and voltage level converter. Goal of invention is achieved by first commutator and pulse generators, which are introduced into transmitter, and second commutator, control pulse delay gate and clipping amplifier, which are introduced into receiver. Converters are designed as pulse counters. Input of first commutator of transmitter is connected to common connection point of AND gates. Its output is connected to input of pulse counter. Outputs of decoder are connected through pulse generator to second inputs of AND gates. Output of voltage level converter in receiver is connected through clipping amplifier to input of second commutator and first input of control pulse delay gate, which second input and connection point of first inputs of AND gates are connected to output of second commutator. Output of control pulse delay gate is connected to input of pulse counter. Bi-directional inputs of commutators are connected to each other by means of communication line. EFFECT: faultless operation of control command transmission system due to asynchronous transmission of control commands between receiver and transmitter while signals runs through communication line. 2 dwg
