Background

The performance of the automobile tire material is closely related to the temperature, and overheating can cause the performance of the tire material to be seriously reduced, so that the tire is rapidly damaged, for example, the tire is burst, and traffic accidents are caused. Therefore, the temperature variation of the tire should be detected on line in real time to control the heat generation of the tire and ensure the safety and reliability of the tire.

The Tire Pressure Monitoring System (TPMS) is an active safety System of an automobile, which employs a wireless transmission technology, collects data such as Pressure and temperature of the automobile Tire in a driving or stationary state by using a high-sensitivity micro wireless sensing device fixed in the automobile Tire, transmits the collected data to a host in a cab, displays related data such as Pressure and temperature of the automobile Tire in a digital form in real time, and reminds a driver to perform early warning in the form of buzzing or voice when the Tire is abnormal (for the purpose of preventing Tire burst).
