Abstract

An induction vehicle detection and identification system comprising electronic identification devices with electronic memory, mounted on vehicles, and a reader capable of reading and/or writing data obtained from devices in HF-band. Devices have a non-volatile memory and are integrated into the vehicle'"'"'s license plate. The reader combined with a magnetic frame is in a dielectric casing, which is mounted under the roadway. It generates an alternating magnetic field, which determines the detection and identification range. Minimum time the reader requires to read discrete responses generated by electronic identification devices and to identify the vehicle is less than 25 ms. The identification devices and the reader exchange data at the rate of 1 Kbit/sec or higher, and provide data encoding and decoding, as well as data access restriction.

Claims

1. An automobile license plate, comprising:

a rectangular dielectric plate having an identifying combination of letters and numbers;

an integrated circuit and a non-volatile memory unit placed inside the plate, with a capacity of 64 bits or more for storing identification data of a vehicle, which includes at least its license plate number;

a multiturn frame, which is made in a plane and framing of the plate, which is connected to the integrated circuit so as to generate an HF-band electromagnetic oscillation resonator with a Q-factor of 20 or more;

wherein the resonator also provides a power supply to the integrated circuit, when the average intensity of an external magnetic field at the resonator'"'"'s resonant frequency is 10 mA/m or more;

wherein the integrated circuit generates modulating signals, modulates/demodulates the resonator'"'"'s alternating current, encodes/decodes signals, and restricts access to data stored in the non-volatile memory unit.

2. The license plate of claim 1, wherein the dielectric plate'"'"'s back side is covered with a magnetic layer.

3. The license plate of claim 1, wherein the integrated circuit is capable of implementing anti-collision ISO 15693, 1800-3 protocols (or compatible).

4. The license plate of claim 1, wherein a spectral width of a modulating signal generated by the integrated circuit enables data exchange at the rate of 1 Kbit/sec or higher.

5. The license plate of claim 1, wherein the integrated circuit is capable of encrypting data to restrict access to the non-volatile memory unit.

6. The license plate of claim 1, wherein the dielectric plate is multi-layered.

7. An automobile license plate, comprising:

a dielectric plate having an identifying combination of letters and numbers;

an integrated circuit and a non-volatile memory placed inside the plate for storing identification data of a vehicle, wherein the identification data includes a license plate number of the vehicle;

a multiturn frame, which is made in a plane and framing of the dielectric plate, which is connected to the integrated circuit, so as to generate an HF-band electromagnetic oscillation resonator with a Q-factor of 20 or more;

wherein the resonator supplies power to the integrated circuit, when an average intensity of an external magnetic field at the resonator'"'"'s resonant frequency is 10 mA/m or more; and

wherein the integrated circuit generates modulating signals, modulates/demodulates the resonator'"'"'s alternating current, encodes/decodes signals, and restricts access to data stored in the non-volatile memory unit.

8. The license plate of claim 7, wherein the dielectric plate'"'"'s back side is covered with a magnetic layer.

9. The license plate of claim 7, wherein the integrated circuit is capable of implementing anti-collision ISO 15693, 1800-3 protocols (or compatible).

10. The license plate of claim 7, wherein a spectral width of a modulating signal generated by the integrated circuit enables data exchange at the rate of 1 Kbit/sec or higher.
