FIELD: physics.
SUBSTANCE: proposed system consists of single stationary reader located at the route start, mobile recording devices arranged on moving objects, and mark point radio beacons arranged at particular route points. Note here that stationary readers and mobile recorders are equipped with limited-range FR-signal transceivers, whilea mark point beacons are provided with limited-range transmitters transmitting in intermittent mode the data containing unique number identifying location of mark point beacon. Moving object coming into controlled zone and equipped with aforesaid recorder receives signal from relevant radio beacons to fix their unique numbers and registration time. Received data is transmitted by mobile recorder after reception of code combination of request intermittently irradiated by stationary reader transceiver.
EFFECT: expanded operating performances.
