TERRITORIAL SYSTEM FOR MONITORING TRANSPORTATION OF ENVIRONMENTALLY HAZARDOUS GOODS Russian patent published in 2011 - IPC G08B25/10 

FIELD: information technology.

SUBSTANCE: equipment mounted on each special vehicle has a radio station, encoding user equipment, a detector, as well as sensors for coordinate information, nature of the goods and signalling sensors. Equipment installed on a check point includes a radio station, a first processor, a comparator unit, an encoder, an ecologist workstation and a second processor. Each radio station has a high-frequency generator, a phase-shift keying device, a power amplifier, a duplexer, a transceiving antenna, a first heterodyne, a 90° phase changer, mixers, second intermediate frequency amplifiers, an adder, multipliers, a narrow bandpass filter, an amplitude detector, a switch, a universal frequency converter, a second heterodyne, a first intermediate frequency amplifier, a bandpass filter, a phase detector, a discrete message generator, a digital scrambler, an analogue message generator, an analogue scrambler, an amplitude modulator, an amplitude limiter, a digital descrambler, a synchronous detector and an analogue descrambler.

EFFECT: broader functional capabilities of the system owing to use of complex signals with combined phase-shift keying and amplitude modulation at one carrier frequency.
