Wireless Communication of Tire Pressure Intelligent Monitoring Systems

A new kind design scheme of sensing system is proposed for car tire safety. The pressure sensor and RF (ray frequency) emitter are installed in automobile tire. The collected data are transmitted to the receiver installed in an automobile by wireless communication channels. Based on the CRC (cyclic redundancy check) algorithm, this paper analyzes and designs the wireless communication, studies and realizes the reliable transmission of the tire pressure and temperature between a transmitting module and a receiving module. The system can measure the tire real-time temperature and pressure, indicate the tire states and alarm at the dangerous states. Therefore, tire exploration can be effectively avoided
