DEVICE FOR REMOTE MONITORING OF LIFE SUPPORT SYSTEMS OF COMPLEX OBJECTS Russian patent published in 2017 - IPC H04B7/00 

FIELD: radio engineering and communications.

SUBSTANCE: proposed invention relates to radio communication and can be used for transmitting control signals from a dispatch station to life support systems (heat supply, water supply, gas supply, power supply, sanitation, ventilation, etc.) of complex objects, as well as for collecting information from the said systems for centralized monitoring and controlling technological processes thereat. Device for remote monitoring of life support systems of complex objects includes a dispatch station and life support systems of complex objects. Dispatch station (each life support system of complex objects) comprises an analogue messages source 1.1 (1.2), a modulator with double type of modulation 2.1 (2.2), a carrier frequency generator 3.1 (3.2), an amplitude modulator 4.1 (4.2), a phase-shift modulator 5.1 (5.2), a discrete message source 6.1 (6.2), a transmitter 7.1 (7.2), the first heterodyne 8.1 (8.2), the first mixer 9.1 (9.2), the first intermediate frequency amplifier 10.1 (10.2), the first power amplifier 11.1 (11.2), a duplexer 12.1 (12.2), a transceiving antenna 13.1 (13.2), a receiver 14.1 (14.2), the second power amplifier 5.1 (15.2), the second heterodyne 16.1 (16.2), the second mixer 17.1 (17.2), the second intermediate frequency amplifier 18.1 (18.2), an amplitude limiter 19.1 (19.2), a synchronous detector 20.1 (20.2), a multiplier 21.1 (21.2), a band-pass filter 22.1 (22.2), a phase detector 23.1 (23.2), unit 24.1 for recording and analysis (actuator 24.2), a total frequency amplifier 25.1 (25.2), an amplitude detector 26.1 (26.2) and a key 27.1 (27.2).

EFFECT: technical task of the invention is increasing noise-immunity and validity of exchanging analog and discrete information between the dispatcher station and the life support systems of complex objects by suppressing spurious signals (noise) received via additional channels.
