摘要:
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.
