Abstract

A system for the identification and automatic detection of vehicles or objects includes an electronic label installed in each of the vehicles or objects, each of these electronic labels having means for memorizing an identification code assigned to a vehicle or object in which the electronic label is installed and radioelectrical transmission and reception means for transmitting this identification code, and at least one mobile reader disposed exterior to the vehicles or objects and movable within a vicinity of these vehicles or objects. Each mobile reader includes a recording memory for recording a file of identification codes of vehicles or objects to be identified, radioelectrical means for transmitting a signal to at least one of the vehicles or objects which prompts the electronic labels of these vehicles or objects to transmit identification codes assigned to these vehicles or objects to the radioelectrical means, comparison means for comparing the identification codes recorded in the file of the recording memory with each identification code transmitted by the electronic labels, and reporting means for reporting to authorities the presence of any vehicle or object whose identification code appears in the file of the recorded memory, as determined by the comparison means. The invention finds particular utility in the automatic detection of stolen vehicles, the purchase of second hand vehicles, and identity checks on motorists.

Claims

1. A system for the identification and automatic detection of objects, comprising:

an electronic label installed in each of said objects, each electronic label having means for memorizing an identification code assigned to an object in which said electronic label is installed, and radioelectrical transmission and reception means for automatically transmitting said identification code upon receipt of a prompt signal; and

at least one mobile reader disposed exterior to said objects and movable within a vicinity thereof, each of said at least one mobile reader including

a recording memory for recording a file of identification codes of said objects to be identified;

radioelectrical means for transmitting said prompt signal to said radioelectrical transmission and reception means of at least one of said objects which prompts each of said radioelectrical transmission and reception means to transmit an identification code assigned to an object in which it is installed to said radioelectrical means;

comparison means for comparing said identification codes recorded in said file with said identification code transmitted by each of said radioelectrical transmission and reception means; and

reporting means for reporting the presence of any of said objects whose identification code appears in said file of said recorded memory and was transmitted by said radioelectrical transmission and reception means, as determined by said comparison means.

2. A system according to claim 1, further comprising broadcasting center for updating said identification codes recorded in said file of said recording memory.

3. A system according to claim 2, wherein said broadcasting center is connected to user stations, at which each of said at least one mobile reader is provided, by an information transmission network.

4. A system according to claim 2, wherein said broadcasting center comprises a computer connected to an information retrieval center.

5. A system according to claim 3, wherein each of said user stations comprises means for updating said recording memory of each of said at least one mobile reader.

6. A system according to claim 5, wherein said recording memory comprises a removable memory card which is removable from said at least one mobile reader by a user.

7. A system according to claim 6, wherein said removable memory card comprises said comparison means.

8. A system according to claim 7, wherein each of said at least one mobile reader is integrated into one of a plurality of service terminals positioned at predetermined locations within said vicinity of said objects.

9. A system according to claim 8, wherein each of said at least one mobile reader comprises a case having a keyboard overlaid on a surface thereof, a display screen, a beeping indicator, and access means for the introduction of said removable memory card.

10. A system according to claim 9, wherein each of said at least one mobile reader comprises a transceiver for periodically updating identification codes of stolen objects in said recording memory.

11. A system according to claim 1, wherein each of said electronic labels comprises a programmable read only memory coupled to a transceiver device which is connected to an antenna.

12. A system according to claim 1, wherein said objects are vehicles.
