摘要
研究非接触式汽车制动性能监测系统(BPMS)的无线数据传输协议,以解决轮胎内置制动加速度信号实时发射传输的冲突问题.根据BPMS中制动信号的特点和传输冲突的原因,结合现行轮胎压力监测系统(TPMS)中解决冲突的办法进行分析比较,提出一种新的多从机循环发射链实时数据无线传输协议,讨论了协议的机理和实现方法,并进行了通信实验验证.结果表明,该协议有效解决了BPMS中无线信号传输的冲突问题.
In order to resolve the data conflict in real-time transmission of braking signals sent by tire-mounted accelerators, a protocol of wireless data transmission of the non-contact automobile braking performance monitoring system （BPMS） was investigated. According to the features of braking signals and the conflict sources during the signal transmission in BPMS, the methods to resolve the data conflict in current tire pressure monitoring system （TPMS） were analyzed and compared, and a new protocol of multi-slaver circular transmission chain for real-time wireless data transmission was proposed. Moreover, the principle and realization of the protocol were discussed and communicating experiments were performed to verify the effectiveness of the proposed protocol in resolving the data conflict in wireless data transmission in BPMS.
