Abstract
The vehicle terminal based on GPRS & CDMA communication takes GD32F105 as the processor, adopts with BDS & GPS positioning technology and communicates with central server by GPRS & CDMA modules. Specific implementation methods according to the hardware and software of vehicle terminal are presented in this paper. Meanwhile, this paper introduces the design of hardware and software of the main modules and processor. By Achieving the real-time communication of the vehicle and central server, made up for the single net vehicle terminal cannot communicate with the central server in real-times when it disconnect with the network.
