基于GPS和GPRS的车辆定位系统应用设计与实现The Design and Implementation of Vehicles Positioning System ApplicationBased on GPS and GPRS摘要全球卫星定位系统利用导航卫星进行测时和测距,它是一种将卫星及通讯很好的结合在一起的技术。

GPS用在大地测量、工程测量、航空摄影、运载工具导航和管制、资源勘察等许多学科中都有着不可取代的优点,并且在经济和社会中都取得了很好的效益。

本设计主要介绍了GPS和GPRS在车辆定位中的工作原理,车载终端的硬件和软件设计。

该系统的设计与实现是GPRS、GPS技术相结合,利用GPRS的数据传输功能,把它接收到的信息通过GPRS网络上的无线通信链路传到建立在Internet网上的服务器上。

以及把车载移动终端的GPS定位信息如何传到建立在Internet网上服务器的问题做了相关的设计,以达到实现在线实时对车辆运行状态、安全状态、技术状态等各类信息的监控。

GPS used in geodetic survey, engineering survey, aerial photography, vehicle navigation and control, resource survey and many other disciplines has irreplaceable advantages in economy and society, and have achieved good benefit.This paper introduces the design of GPS and GPRS in vehicle positioning in the working principle, hardware and software design of the vehicle mounted terminal. The design and implementation of this system is GPRS, GPS technology, using GPRS data transmission function, put it to receive information through the GPRS network wireless communication link to the online server based on Internet. As well as the vehicle mobile terminal GPS positioning information how to build in the Internet online server problem introduced the, to achieve real-time operating state of the vehicle, security, technical condition and other types of information monitoring.Key words: GPRS; GPS positioning system; Vehicle terminal目录第1章绪论 (I)1.1课题背景 (I)1.2车载智能终端的发展 (I)1.3车载研发的国内外现状..........................I I 第2章GPS全球卫星定位系统.
