The Design of Embedded Display Terminal Based on Vehicle GPS System

本文提出的嵌入式汉显终端设计方案,涉及一种车载卫星定位系统,通过串口通信利用车载GPS终端提供的定位信息和GSM/GPRS无线通讯功能实现实时显示定位信息、车载电话、短信息及语音提示等功能,达到人机交互的目的,同时结合中心软件也能更好地实现车辆调度功能。

This paper proposed a design of embedded display terminal based on vehicle GPS System.By using of serial communication, it receives the GPS signals from the vehicle GPS terminal and displays real-time position information and message,extends its GSM/GPRS function to and provides voice reminding functions.The embedded display terminal has the advantages of multifunction and practicability.
