| Abstract: | A communication method that is used in vehicle monitoring system is proposed based on the big- section and single frequency of TDMA. The communication protocols among physical level, data - link level and network level which are adopted in the monitoring system are given respectively. Some key technologies are discussed, such as CRC detecting, set - up time of PTF, second pulse signal of GPS OEM board that are used in system synchronization and warning- handling system. At the end, the system is verified. |
