Abstract

The invention relates to a method of replacing a defective sensor (100) of a surveillance system for monitoring in particular the pressure of the wheels of a vehicle (V) of the type of that comprising: wireless sensors (100) disposed in each wheel and a receiver; a unique identifier number being assigned to each sensor (100) thus making it possible for the receiver to identify the signal. This method is noteworthy in that it consists in: removing the defective sensor (100); identifying and logging the unique identifier number of the defective sensor (100); identifying and logging the communication protocol used on the vehicle; assigning said unique identifier number to a new virgin sensor (200, 200′) with neither assigned communication protocol nor assigned identifier number and simultaneously; programming the new sensor (200, 200′) so that it utilizes said communication protocol. The invention also relates to the device D and the sensor 200 making it possible to implement same. Applications: detection of data available inside the wheels of a vehicle.

Claims

1-11. -11. (canceled)

12. A method of replacing a defective sensor in a monitoring system, in particular for the pressure on the wheels of a vehicle, of the type comprising:

wireless sensors placed in each wheel and a receiver,

a unique identifying number being allocated to each sensor thus enabling the receiver to identify the signal,

characterized in that it comprises;

removing the defective sensor,

identifying and recording the unique identifying number of the defecting sensor,

identifying and recording the communication protocol used on the vehicle and allocated to the defecting sensor,

allocating the unique identifying number to a new blank sensor without a communication protocol or identifying number allocated, and simultaneously,

allocating in the memory of the sensor at the same time as the unique identifier, information for locating the wheel in which the sensor is placed,

programming the new sensor so that it uses the communication protocol used by the defective sensor.

13. A method according to claim 12, characterized in that the unique identifying number of the defective sensor is read by a tool of the portable electronic box type.

14. A method according to claim 12, characterized in that it comprises editing a label comprising the unique identifying number.

15. A method according to claim 12, characterized in that the unique identifying number of the defective sensor is read visually on the defective sensor.

16. A device for implementing the method according to claim 12, characterized by the fact that it comprises a tool of the low-frequency portable electronic box type that reads the number of the defective sensor, stores it in memory and transfers it into the memory of a new sensor.

17. A device for implementing the method according to claim 12, characterized by the fact that it comprises a tool of the electronic box type equipped with a sensor accommodation and communication plate for purposes of reading information and/or transmitting information by contact in order to read the number of the defective sensor, store it in memory and transfer it into the memory of a new sensor.

18. A device for implementing the method according to claim 12, characterized by the fact that it comprises a tool of the low-frequency portable electronic box type that programs the sensor so that it adopts the communication protocol used by the defective sensor.

19. A sensor for implementing the method according to claim 12, characterized by the fact that it is preformed with an interface connected with the subassemblies accommodated by the housing of the sensor and with which the accommodation plate of the electronic box cooperates.

20. A method according to claim 12, characterized in that it comprises storing in memory in a database the maintenance operation performed for traceability.

21. A method according to claim 12, characterized in that it comprises interrogating the new sensor after programming, the sensor responding for validation of the state thereof.
