AUTOMATED SYSTEM EMERGENCY AND ENVIRONMENTAL MONITORING OF THE ENVIRONMENT OF THE REGION

摘要

FIELD: physics.;SUBSTANCE: system has stationary and mobile monitor stations, direct and feedback links and a central control station. Each of the stationary and mobile stations includes an information pre-processing unit, an encryption unit, a noiseless coding unit, an analogue message unit, a receiver, a control unit and direct and feedback channels. Each mobile station further includes a position finding unit. Each transceiver has a driving generator (20), a phase-shift keying device (21), an amplitude modulator (22), first and second heterodynes (23, 30), first, second and third mixers (24, 31, 57), a first intermediate frequency amplifier (25), first and second power amplifiers (26, 29), a duplexer (27), a transmit/receive antenna (28), first and second second-intermediate frequency amplifiers (32, 58), an amplitude limiter (33), a synchronous detector (34), first and second multipliers (35, 61), a band-pass filter (36), a phase detector (37), a -90° phase changer (56), a +90° phase changer (59), an adder (69), a narrow-band filter (62), an amplitude detector (63) and a switch (64).;EFFECT: high reliability of monitoring results.;7 dwg
