REMOTE MONITORING SYSTEM FOR SUPPLY OF MATERIAL AND TECHNICAL RESOURCES FOR RECOVERY OF INFRASTRUCTURE OBJECTS Russian patent published in 2020 - IPC G07C5/08 

FIELD: construction.

SUBSTANCE: disclosed system relates to the field of technical means of monitoring and recording movement of special construction equipment and can be used when delivering material and technical resources by trailers and special machines for restoring infrastructure facilities. System comprises on each monitored volume pressure sensor 1, a body position sensor 2, AND element 3, encoding unit 4, transmitter 5, a fuel flow sensor 11, travel distance sensor 12, high frequency generator 13, phase manipulator 14, power amplifier 15, transceiving antenna 16, receiving antenna 33, GPS signal receiver 34, microprocessor 35, duplexer 36, multipliers 37, 38, 53 and 54, narrow-band filters 39 and 55, low-pass filters 40 and 56, demodulators 51 and 52 of complex phase-shift keyed signals, subtraction unit 59, phase-inverter 57 and 58. Control point comprises receiving antenna 17, high frequency amplifier 18, decoder 7, recording unit 8, prohibition element 9, pulse duration generator 10, multipliers 24, 25, 62 and 63, narrow-band filters 26 and 64, mixer 21 and 70, search unit 19, heterodynes 20 and 69, intermediate frequency amplifiers 21 and 71, correlator 72, threshold unit 73, additional registration unit 32, fuel consumption counter 30, travel distance counter 31, amplitude detector 23, switch 28 and 74, frequency meter 29, complex phase-shift keyed signal demodulators 60 and 61, phase inverters 66, 67, 76, 79 and 82, transceiving antenna 41, GPS signal receiver 42, computer 43, encoding unit 44, transmitter 45, high frequency generator 46, phase manipulator 47, power amplifier 48, duplexer 49, band-pass filters 78 and 81, adders 77, 80 and 83.

EFFECT: technical result is high selectivity and noise immunity of panoramic receiver and reliability of exchange of discrete information between controlled equipment and control point by suppression of false signals (interference), received by intermodulation channels and channel of direct passage.
