Design and Implement of Intelligent Vehicle Navigation System Based on GPS

针对车辆在行驶过程中的导航定位问题,实时接收车辆的经纬度、高度、方向等位置信息的需求,设计一款基于GPS的车载导航系统,该系统以ARM内核的微控制器为硬件部分的核心,GPS模块接收到的卫星信号通过串口传送到开发板扩展的LCD上显示,在PC机上使用软件接收GPS模块的信息与地图匹配实现导航,利用GPRS网络实现定位数据的远程传输。实验证明系统实现GPS定位和信息获取、有良好稳定性,满足车载导航的要求。

This paper aims at the problem of navigation and positioning in the process of a moving vehicle, and the requirements of real-time vehicle position acquisition, such as longitude and latitude, altitude, direction, to design an intelligent vehicle navigation system based on GPS. The system is with ARM core microcontroller as the core of hardware, the GPS module receives satellite signals and then via serial port display on the LCD. It uses software to receive GPS navigation module information and implement map matching navigation, uses GPRS network to implement remote transmission of location data. Experiment shows that system implementation GPS position and access to information have good stability, meet the requirements of car navigation.
