Tire Pressure Monitoring System Design Based On ZigBee

The Tire Pressure Monitoring System (TPMS) is following the Anti-lock Braking System (ABS), Airbag Protection System (SRS), a new generation of high-tech automotive electronics safety warning system, it is a in cars withof tire pressure and temperature in real-time automatic monitoring, early warning and tire abnormal condition, active safety systems to ensure the traffic safety. Directly based on the current active automotive tire pressure monitoring system is separated from the RF chip processor design, the frequency of433MHZ wireless system caused by large size, high power consumption and self-organizing network is poor, weak anti-jamming ability, etc. The key technical problems, design a wireless sensor network based on the active type automobile tire pressure monitoring system directly. The system with ZigBee technology, high reliability, low cost, low power consumption, high security features, can effectively avoid the tire monitoring node sends the data conflict, and to reduce system energy consumption and prolong network life. Real time automatic monitoring tire inner pressure, temperature and other status information, so as to effectively guarantee the safety car.
