DEVICE FOR REMOTE MONITORING OF LIFE SUPPORT SYSTEMS OF SPECIAL FACILITIES Russian patent published in 2020 - IPC H04B7/00 

FIELD: radio engineering and communication.

SUBSTANCE: invention relates to radio communication and can be used to transmit control signals from a control station to life support systems (heat supply, water supply, gas supply, power supply, sewage, ventilation, etc.) of complex objects, as well as for collecting information from the said systems for centralized monitoring and controlling technological processes thereat. Proposed device comprises dispatcher station and life support systems of complex objects. Dispatching station comprises an analogue message source, a modulator with a double modulation type, a carrier frequency generator, an amplitude modulator, a phase manipulator, a discrete message source, a transmitter, a first heterodyne, a first mixer, a first intermediate frequency amplifier, a first power amplifier, a duplexer, a transceiving antenna, a receiver, a second power amplifier, a second heterodyne, a second mixer, amplifier of second intermediate frequency, amplitude limiter, synchronous detector, multiplier, band-pass filter, phase detector, recording and analysis unit, total frequency amplifier, third heterodyne and third mixer.

EFFECT: technical result consists in improvement of noise immunity and reliability of analogue and discrete information exchange between dispatching station and life support systems of complex objects by suppression of false signals (interference) received via additional channels.
