Abstract: As an important part of the intelligent transportation system，on-board GPS system achieves real-time positioning and monitoring of the moving vehicles． The creation of the system was based on the TQ2440 embedded development board which was produced by Embedsky Tech for the hardware platform and took Linux operating system as software platform． The first step was the selection of development platform and the establishment of the system architecture; the second step was the design of system function; next，Mapinfo7． 0 was used to draw electronic map，and the relevant program was compiled in QT framework，and the finished program was transplanted into ARM development board; the last step was the realization of data acquisition，maps scanning and GPS positioning function．

Key words: on-board GPS, Linux, electronic map, QT

摘要： 作为智能交通系统的重要组成部分,车载GPS 定位系统实现了移动车辆实时定位与监控的功能。该系统的 创建是以天嵌公司生产的TQ2440 嵌入式开发板为硬件平台,以Linux 操作系统为软件平台。首先是开发平台的选 取以及系统整体架构的建立,其次是系统的功能设计,接着利用Mapinfo7. 0 绘制电子地图并在QT 框架下进行相关 程序的开发,然后将其移植到ARM 开发板,最终,成功地实现了数据采集、地图浏览和GPS 定位的功能。
