Abstract:Many outstanding advantages of GPRS transmission mode was analyzed, and a novel type of in-vehicle information platform was put forward, which focused on improving modernization degree of city traffic. Also, based on the actual test status, function of the system, the frame of hardware and the implementation of software and so on were elaborated. The key technique which used to log on GPRS network were emphasized, the ways and means on how to improve the performance of system were detailed . The test result shows the data lost rate is between 5%~6% and the data delay rate is less than 1% after consummating the system. It possesses high practical value, and provides some significative theory and test results for other in-vehicle monitoring system development.
Keywords:integrated communication/navigation/identification system  data transmission  monitoring control  packet switching  PPP  embedded system
