摘要
本文首先分析了终端定位LBS系统的各个组成部分,研究了VC下开发MapX的方法,对最短路径算法及单片机控制、GSM模块开发等关键技术进行了详细介绍;然后结合SR-92GPS模块、西门子MC39iGSM模块,采用C8051F340双串口单片机最终设计出系统的移动终端;并以MapX为GIS平台实现了具备位置查询、要素信息服务、最短路径服务、客户轨迹回放等功能的系统平台。
The paper firstly analyzed the components of the terminal location LBS system,developed MapX under VC environment,and described some key technologies in detail,such as Shortest Path Algorithm、MCU control,GSM Module Development;then achieved the mobile terminal which was designed by C8051F340 MCU combined with SR-92GPS module and Siemens MC39i;finally the system platform which realized some functions based on MapX,such as Location Search、Information Elements Service,Shortest Path Service and Customer Track Playback.
