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. A method of replacing a first sensor in a monitoring system, for the pressure on the wheels of a vehicle, the first sensor being defective, the monitoring system including wireless sensors placed in each wheel and a receiver, wherein a unique identifying code is assigned to each sensor thus enabling the receiver to identify a signal, the monitoring system being configured to communicate according to a selected one of a plurality of communications protocols, the method comprising the following steps:

removing the first sensor;

identifying and recording the unique identifying code of the first sensor;

recognizing the vehicle;

identifying, responsive to the recognizing step, the communication protocol used on the vehicle;

responsive to the second identifying step, transferring a first data item to a second sensor, the first data item including programming for one of the plurality of communication protocols;

subsequent to the identifying steps, transferring a second data item, in addition to the first data item, to the second sensor, the second data item including the unique identifying code of the first sensor;

subsequent to the identifying steps, transferring a third data item, in addition to the first data item and the second data item, to the second sensor, the third data item including information for locating the wheel in which the second sensor is placed,

thereby enabling a person to perform a sensor maintenance operation without requiring dialog with a diagnosis system onboard the vehicle, wherein the step of recognizing the vehicle includes visual identification of a make and model of the vehicle.

2. A method according to claim 1, characterized in that the unique identifying code of the defective sensor is read by a portable tool.

3. A method according to claim 1, characterized in that the method further comprises editing a label comprising the unique identifying code.

4. A method according to claim 1, characterized in that the unique identifying code of the defective sensor is read visually on the defective sensor.

5. A method according to claim 1, characterized in that the method further comprises storing in memory in a database the maintenance operation performed for traceability.

6. A method according to claim 1, characterized in that the method further comprises interrogating the new sensor after programming, the sensor responding for validation of the state thereof.

7. A method according to claim 1 wherein transferring the first data item includes transferring programming for the communication protocol identified in the second identifying step.

8. A method according to claim 1 wherein the first and second transferring steps are simultaneously performed.

9. A method of replacing a first sensor in a monitoring system, for the pressure on the wheels of a vehicle, the first sensor being defective, the monitoring system including wireless sensors placed in each wheel and a receiver, wherein a unique identifying code is assigned to each sensor thus enabling the receiver to identify a signal, the monitoring system being configured to communicate according to a selected one of a plurality of communications protocols, the method comprising the following steps:

removing the first sensor;

identifying and recording the unique identifying code of the first sensor;

recognizing the vehicle;

identifying, responsive to the recognizing step, the communication protocol used on the vehicle;

responsive to the second identifying step, transferring a first data item to a second sensor, the first data item including programming for one of the plurality of communication protocols;

subsequent to the identifying steps, transferring a second data item, in addition to the first data item, to the second sensor, the second data item including the unique identifying code of the first sensor;

subsequent to the identifying steps, transferring a third data item, in addition to the first data item and the second data item, to the second sensor, the third data item including information for locating the wheel in which the second sensor is placed,

thereby enabling a person to perform a sensor maintenance operation without requiring dialog with a diagnosis system onboard the vehicle, wherein the step of recognizing the vehicle includes recording a vehicle identification code.

10. A method of replacing a first sensor in a monitoring system, for the pressure on the wheels of a vehicle, the first sensor being defective, the monitoring system including wireless sensors placed in each wheel and a receiver, wherein a unique identifying code is assigned to each sensor thus enabling the receiver to identify a signal, the monitoring system being configured to communicate according to a selected one of a plurality of communications protocols, the method comprising the following steps:

removing the first sensor;

identifying and recording the unique identifying code of the first sensor;

recognizing the vehicle;

identifying, responsive to the recognizing step, the communication protocol used on the vehicle;

responsive to the second identifying step, transferring a first data item to a second sensor, the first data item including programming for one of the plurality of communication protocols;

subsequent to the identifying steps, transferring a second data item, in addition to the first data item, to the second sensor, the second data item including the unique identifying code of the first sensor;

subsequent to the identifying steps, transferring a third data item, in addition to the first data item and the second data item, to the second sensor, the third data item including information for locating the wheel in which the second sensor is placed,

thereby enabling a person to perform a sensor maintenance operation without requiring dialog with a diagnosis system onboard the vehicle, wherein the step of recognizing the vehicle includes visual identification of a make and model of the vehicle, or recording a vehicle identification code.

11. A method according to claim 10, characterized in that the unique identifying code of the defective sensor is read by a portable tool.

12. A method according to claim 10, characterized in that the method further comprises editing a label comprising the unique identifying code.

13. A method according to claim 10, characterized in that the unique identifying code of the defective sensor is read visually on the defective sensor.

14. A method according to claim 10, characterized in that the method further comprises storing in memory in a database the maintenance operation performed for traceability.

15. A method according to claim 10, characterized in that the method further comprises interrogating the new sensor after programming, the sensor responding for validation of the state thereof.

16. A method according to claim 10 wherein transferring the first data item includes transferring programming for the communication protocol identified in the second identifying step.
