基于ARM及无线传感器的轿车胎压监测系统的设计

摘要

This paper introduced the hardware constitution and software design method of Tire Pressure Monitoring System, described the design projects of the remote monitoring module based on Infineon SP30 sensor and TDK5100F RF transmitter and receiver module based on EsayARMl138 development board and TDA5210 RF receiver. The system can issue appropriate sound or light alarm against different anomalies until the tire pressure and temperature return to normal. The data processing algorithm was optimized as to reduce the system power dissipation and increase the service life,which had important significance to the popularity of the monitoring system and performance optimization.%介绍了轮胎压力监测系统的硬件及软件设计方法,阐述了基于英飞凌SP30传感器和TDK5100F射频发射芯片的轮胎监测模块设计方案和基于EasyARM1138和TDA5210射频接收芯片的中央主机接收模块的设计方案,实现了根据不同的异常情况发出相应的声、光报警,直至轮胎压力和温度恢复正常,并优化数据处理算法减小系统功耗,延长使用寿命,对胎压监测系统的普及和性能优化有重要意义.
