山东科技大学学士学位论文 摘要 摘 要

随着人们生活水平的不断提高，汽车的数量也急剧增加，随之而来的是严重的交通拥堵，车辆分散不易管理等问题，更为严重的是交通事故的频发。车辆定位监控系统集通信技术、GPS定位技术、WebGIS地理信息系统技术及其数据库技术于一体，能有效地提高道路的利用效率，减少车祸的发生，降低能源的消耗，给人们带来更高的生活质量。该系统也是智能交通系统的重要内容，对其进行研究与开发具有重要意义。

车辆监控系统由车载终端硬件、通信和监控三部分组成。车载终端通过GPS进行数据和相关信息采集, 通过 GPRS无线通信和Internet网络将处理好的数据发送到监控中心, 服务器端软件对数据进行解析后存储在数据库中，监控中心通过网站服务器程序访问数据库，将有关数据和相关信息进行技术处理，客户通过网站查询车辆信息。根据设计需要，服务器数据库选用MySQL，它具有体积小、速度快、总体拥有成本低的特点，方便设计、运行和管理。设计还考虑到人们出行时路径选择的问题，采用迪杰斯特拉算法实现了最优路径的选取。

山东科技大学学士学位论文 摘要 Abstract

With the continuous improvement of people's living standard, the number of cars is increasing rapidly, followed by severe traffic congestion and vehicle dispersion probelom and so on. What more serious is the traffic accidents happened frequently. Vehicle positioning and monitoring system integrated communication technology, GPS technology, Web GIS geographic information system technology and database technology, can effectively improve road utilization efficiency, reduce traffic accidents, reduce energy consumption, bring people a higher quality of life. The system is the important content of intelligent transportation system, its research and development is of great significance. Vehicle monitoring system consists of vehicle terminal hardware, communication and monitoring three parts. Vehicle terminal collect data and related information through the GPS, sent the processed data to the monitoring center through the GPRS wireless communication and Internet network. Server software analyzes the data and stores them into the server database, and monitoring center through the web server program to access the database, the data and related information is technically processed, customers get vehicle information through the website. According to the demand of design, the MySQL server database is selected, and which has the advantages of small volume, high speed, and low total cost of ownership, the convenience of design, operation and management. The design also takes into account people‘s travel route choice problem, the Dijkstra algorithm is used to achieve the optimal path.

Keywords: GPRS/GSM/WEBGIS; MySQL; Dijkstra
