文档介绍：摘要
随着我的快速发展,汽车行业也蓬勃发展起来。汽车的增长速度远远超过公路的增长速度,汽车拥有量的急剧增加和城市现代化交通建设的相对滞后导致城市交通情况不断恶化。同时,现代物流对运输车辆和货物安全与准时调运的要求、公交与出租车的运营管理、大型的企事业单位日常车辆管理也都对车辆的监控与导航有迫切的需求。而且随着旅游行业的发展,人们急需要一种可以随时随地知道自己方位和目的地的方便设备。
本系统由GPS数据采集并显示、地图显示两大部分组成,模拟GPS导航的过程。通过GPS模块、ARM9硬件环境、嵌入式Linux操作系统等模块来完成整个体系的运作,使其实时采集GPS数据,然后将GPS数据对应的地图显示出来,再利用串口将数据送入PC机数据库中实现查询等一系列功能。本设计的特点在于界面友好、用户易操作、功耗低、便于长时间户外导航。

ABSTRACT
Along with our country economy level of development,the automobile industry also growth of the car much faster than the speed of growth in the highway,the car ownership dramatically increased and the construction of modernization in the city traffic conditions relative lag the same time, the modern logistics for transportation vehicles and the goods on time and the requirement of transportation safety, bus and taxi operational management,large enterprises and institutions of the daily vehicle management are also on the vehicle of monitoring and navigation are pressing with the development of the tourism industry,people need a equipment which can at any time anywhere know their positions and the destination conveniently.
This system consists of GPS data collection,map posed of two parts, simulated GPS navigation the GPS module,ARM9 hardware environment, embedded LINUX operating system,TFT touch screen and other modules plete the operation of the entire system to collect real-time GPS data,GPS data and then display the corresponding map,re-use the data into the PC serial port machine in the database queries, and so to achieve a series of design feature is user-friendly,user easy to operate,low power consumption,easy to navigate a long time outdoors.
Key Words:ARM;LINUX;GPS;embedded operating system
