【摘要】：随着我国社会经济的发展,国民的汽车拥有量急剧上升,对于车辆的有效监控管理成为公众关注的热点问题之一。车辆监控系统集合了计算机技术、卫星导航技术、无线通讯技术,能够很好的满足了人们对于车辆监控的需求。目前,我国车辆监控系统主要依赖美国的GPS技术,随着我国北斗卫星导航系统的全面推广,开发基于北斗卫星导航的车辆监控系统拥有巨大的应用前景。本文设计了基于北斗定位的车辆监控系统,并在此基础上,对地图匹配算法进行了研究和设计。论文的主要工作如下：研究了卫星导航技术、GIS技术、GPRS技术的基本原理；分析了车载终端、远程服务器系统、监控客户端的功能需求；根据系统的设计需求、设计原则及工作原理,给出了系统总体设计方案。以Atmega128处理器为主控芯片,外部扩展MXTOS2-200北斗卫星接收模块、SIM300GPRS通信模块及外围电路,进行了车载终端的硬件设计。设计了车载终端的定位、通信功能程序流程,并在AVR STUDIO开发环境下编程实现。针对车载终端的远程监控,进行了远程监控中心的设计,包括了远程服务器设计、数据库设计、监控客户端设计。利用数据库技术、套接字技术、GIS技术,设计并实现了远程监控中心的数据通信、GIS显示和远程控制等功能。对于常用地图匹配算法在效率和精度上的缺陷,结合电子地图和车辆行驶特点,提出了基于模糊综合评判的改进算法。在多种道路地形特征下,验证了算法的可靠性,并在实际系统中对算法进行了实现。
[Abstract]:With the development of our country ' s social economy , the automobile ownership of the people has increased sharply , and the effective monitoring and management of the vehicle becomes one of the hot issues of public concern . The vehicle monitoring system is mainly dependent on the GPS technology of the United States . With the popularization of the Beidou satellite navigation system in China , the vehicle monitoring system based on Beidou satellite navigation has great application prospect .

The basic principle of satellite navigation technology , GIS technology and GPRS technology is studied .
The function demand of the vehicle - mounted terminal , the remote server system and the monitoring client is analyzed .
According to the design requirement , design principle and working principle of the system , the overall design scheme of the system is given .

Taking Atmega128 processor as the main control chip , the external expansion MXTOS2 - 200 Beidou satellite receiving module , the SIM 300 GPRS communication module and the peripheral circuit , the hardware design of the vehicle - mounted terminal is carried out . The positioning and communication function program flow of the vehicle - mounted terminal is designed and realized under the development environment of AVR STUDIO .

Aiming at the remote monitoring of the vehicle - mounted terminal , the design of the remote monitoring center is carried out , including the design of the remote server , the design of the database and the design of the monitoring client . The data communication , GIS display and remote control of the remote monitoring center are designed and realized by using the database technology , the socket technology and the GIS technology .

This paper proposes an improved algorithm based on fuzzy comprehensive evaluation for the defect of common map matching algorithm in efficiency and precision . Based on the characteristics of electronic map and vehicle , the reliability of the algorithm is verified and the algorithm is implemented in the actual system .
