摘要
详细阐述了城市车辆导航定位技术的发展现状,深入分析了城市车辆导航定位的特点和需求,在此基础上利用嵌入式开发平台设计实现了基于GPS和RFID(无线射频识别)的车载定位系统,系统主要由GPS模块、RFID模块、GPRS(general packet radio service,通用分组无线服务)模块等部分组成。该系统通过接收GPS数据和RFID数据,依托ARM平台进行分析处理,分析处理的结果通过GPRS模块发送到监控中心以实现对车辆的监控与导航。该系统具有实时性好、可靠性高、功耗体积小等显著特点,能够满足现代城市车辆的导航与定位需要。
The current situation of urban vehicle navigation/positioning technology is expounded and the characteristics and needs of urban vehicle navigation/positioning is analyzed thoroughly.Following above exposition and analysis a vehicle-mounted positioning system based on GPS-RFID（radio frequency identification）,which is designed and implemented by using embedded platform,is introduced.This system mainly consists of the GPS module,RFID module,GPRS（general packet radio service） module,etc.By receiving GPS data and RFID data as well as using ARM platform to conduct analysis and processing,the system sends the results of the analysis through GPRS module to the monitoring center so as to realize the monitoring and navigation of vehicle.The system is characterized by real-time,high reliability,low power-consumption,small volume,etc.,meeting the need of modern urban vehicle navigation and positioning.
