The novel non-contact automobile braking performance monitoring system(BPMS)consists of tiremounted accelerometers,whose radial accelerations sampled from four tires should be transmitted to outer receiving system in drivefs cab of automobile by real-time wireless communication.In the research of wireless communication module,there exists data conflict in transmission.The sources of data conflict are discussed,analyzed and com pared with the approaches of solving data conflict in current tire pressure monitoring system(TPMS),and finally proposed a new protocol of multi-slave station circular transmission chain for real.Time wirleless communication.The experiments prove that it Can solve efficiently the data conflict of wireless communication in BPMS.
