Telematics mobile wireless data communications system

Abstract In recent years, with the steady growth of China's economic development, people become frequent traffic travel, travel mode choice more and more followed by increasingly acute traffic problems, people began turning their attention to the traffic problems. With the development of the times, things came to an unprecedented level, we can see that in the field of intelligent transportation technology began to have things like a big stride development and innovation, networking concept car which came into being. Things efficiency through information transmission system can greatly increase between the vehicle, the frequency of the transmission of information between vehicles and public transport, which can improve traffic efficiency, thereby providing an important guarantee for the effective coordination and management of transportation.

This paper describes the process of mobile communication wireless data communication system, a communication system design and implementation. Key-vehicle terminal wireless data communication system design, component selection, module design and interface design, embedded system application technology, RFID radio frequency identification technology, GPRS wireless communication technology and GPS positioning technology and vehicle location information collection, information about items identification, remote transmission of information and other functions.

In the hardware on the basis of a thesis based on embedded system hardware design vehicle terminal communication system for GPS positioning module, RFID radio frequency identification module and GPRS wireless data transmission module communication module hardware design, as well as the communication module software applications. So that the system can transfer the vehicle condition, driving directions and other information to a remote communication management terminal,
