TERRITORIAL SYSTEM FOR CONTROLLING TRANSPORTATION OF VERY IMPORTANT AND DANGEROUS GOODS Russian patent published in 2010 - IPC G08B25/10 

FIELD: physics.

SUBSTANCE: system has equipment on each special transportation vehicle, at the control station and on each check station. Each transportation vehicle is fitted with a coordination information sensor, a sensor for the nature of the goods, signalling sensors, a coding device, a recording device, a radio station with a transceiving antenna, and the control station is fitted with a radio station with a transceiving antenna, two processors, a comparator unit, a coding device and an operator workstation. Each radio station has a high frequency generator, a phase-shift keying device, a power amplifier, a duplexer, two heterodynes, two 90° phase changers, two mixers, two first intermediate frequency amplifiers, an adder, two multipliers, a narrow band-pass filter, an amplitude detector, a switch, a band-pass filter and a phase detector. An identification mark (surface acoustic wave interdigital transducer) has a piezoelectric crystal, a microstrip antenna, electrodes, buses and reflectors. The scanning device has a high frequency generator, a power amplifier, a duplexer, a transceiving antenna, a high frequency amplifier, a phase detector, a computer, a heterodyne, a mixer, a third intermediate frequency amplifier, a phase-shift keying device and a power amplifier.

EFFECT: system is characterised by broad functionalities and provides high reliability of controlling transportation of very important and dangerous goods through remote detection of the event and time at which special transportation vehicles transporting said goods pass through check stations.
