SPECIAL CARGO TRANSPORTATION MONITORING SYSTEM Russian patent published in 2020 - IPC G08B25/10 

FIELD: physics.

SUBSTANCE: invention relates to monitoring and alarm signalling equipment and can be used for on-line monitoring and control of transportation of especially important and dangerous cargoes. Essence: 1.i equipment arranged on each special vehicle comprises sensor coordinate information 2.1, cargo nature sensor 2.2, special sensors 2.3, subscriber device 3.i of encoding, registration device 4.i, radio station 5.i, transceiving antenna 5.i, identification mark 38.i (i = 1, 2, … , n). Equipment arranged at control point 7 comprises transceiving antenna 8, radio station 9, processors 10 and 14, comparison unit 11, coding device 12 and operator workstation 13. Each radio station 9 (5.1) comprises high-frequency generator (15.1), phase manipulator (16.1), power amplifier 17 (17.1), duplexer 18 (18.1), first heterodyne 19 (19.1), phase changers 20 (20.1) and 25 (25.1) by 90°, mixers 21 (21.1) and 22 (22.1), first intermediate frequency amplifiers 23 (23.1) and 24 (24.1), adder 26 (26.1), multiplier 27 (27.1), narrow-band filters 28 (28.1), 60 (60.1) and 61 (61.1), amplitude detectors 29 (29.1), 62 (62.1) and 63 (63.1), switch 30 (30.1), multiplier 35 (35.1), band-pass filter 36 (36.1), phase detector 37 (37.1), controlled phase changers 58 (58.1) and 59 (59.1), subtracting unit 64 (64.1), multiplier 67 (67.1), low-pass filters 65 (65.1) and 68 (68.1), inverse amplifiers 66 (66.1) and 69 (69.1).

EFFECT: technical result is high noise-immunity and reliability of exchanging discrete information between a control station and each special vehicle by completely suppressing false signals (interference) received over mirror channels.
