| Abstract: | 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. |
