INDUCTION SYSTEM FOR DETECTING AND IDENTIFYING VEHICLES, INDUCTION REGISTRATION NUMBER PLATE AND INDUCTION READER Russian patent published in 2014 - IPC G08G1/17 G08G1/42 B60R13/10 

FIELD: physics; control.

SUBSTANCE: group of inventions relates to traffic control devices in order to record or control movement using vehicle identification. The induction system for detecting and identifying vehicles comprises electronic identification means with electronic memory a reader for reading and/or recording information from the electronic identification means in the HF frequency range, mounted on the vehicles. The electronic vehicle identification means are in form of a resonator embedded in the vehicle registration number plate. The resonator has a multi-loop frame and a microchip connected thereto, said microchip being powered by electric current induced in the resonator by an external alternating magnetic field and having non-volatile memory. The reader is equipped with a magnetic frame mounted in a dielectric housing under the road surface at a depth of 1 m, which enables to form an alternating magnetic field around it, which makes up the coverage area of the magnetic frame.

EFFECT: simplifying the system to a single-range system, avoiding the need to build structures above or on the side of the road surface for mounting antennae, and providing reliable and safe operation of the system.
