【摘要】：近年来,随着世界经济的迅猛发展,交通问题日益严峻,在此背景下,智能交通系统(ITS)作为解决交通问题的全新方案应运而生。智能交通系统是当前交通领域研究的前沿课题,也是解决交通拥堵,改善行车安全,提高运营效率,并减少环境污染等的最佳途径。而车辆监控系统是ITS的一个典型应用,它可以通过对车辆进行全程实时定位监控,保障车辆的运输安全,又可方便管理人员指挥调度,提高车辆使用效率。本文以陕西交警大队的车辆监控系统项目为背景,探讨车辆监控系统的技术开发实现过程及方法。所设计的车辆监控系统由车载终端、通信服务器、车辆监控软件平台三大部分组成。车载终端和车辆监控软件平台之间通过通信服务器实时交互,三者组成了一个动态监控网络,对车辆进行定位和跟踪,在车辆监控软件平台电子地图上实时显示车辆行驶轨迹,并存储车辆的位置、定位时间等状态参数,便于后期查询。本文主要内容如下： (1)分析了车辆监控系统的总体结构设计。介绍了系统的设计原则及思想,并针对系统的具体组成,详细解析了各个部分的作用及它们之间的数据交换方式。 (2)完成了车辆监控系统软件平台的设计与实现。为了减少对浏览器的依赖性,且考虑到内网安全问题,无法连接到互联网的情况,本平台采用OpenLayers API进行电子地图的开发,论文展现了其详细实现过程,其中包含实时监控、历史轨迹回放、车辆调度三个基本功能。 (3)针对历史轨迹回放过程中,可能出现的停车时间过长降低系统响应性能的问题,论文进行了轨迹数据压缩优化,并获得了良好的效果。
[Abstract]:In recent years, with the rapid development of the world economy, traffic problems become increasingly serious, in this context. Intelligent Transportation system (its) as a new solution to traffic problems emerged as the times require. Intelligent Transportation system (its) is not only the frontier of the current research in the field of transportation, but also to solve traffic congestion and improve traffic safety. The vehicle monitoring system is a typical application of ITS, which can ensure the transportation safety of vehicles by real-time positioning monitoring. It can also be convenient for managers to command and dispatch, and improve the efficiency of vehicle use. In this paper, based on the vehicle monitoring system project of Shaanxi traffic police brigade, the process and method of vehicle monitoring system technology development are discussed. The vehicle monitoring system is designed by vehicle terminal and communication server. The vehicle monitoring software platform consists of three parts. The vehicle terminal and vehicle monitoring software platform interact with each other through the communication server in real time. The three constitute a dynamic monitoring network to locate and track the vehicle. On the electronic map of the vehicle monitoring software platform, the track of the vehicle is displayed in real time, and the status parameters such as the position of the vehicle and the positioning time are stored, which is convenient for the later inquiry. The main contents of this paper are as follows: 1) the overall structure design of the vehicle monitoring system is analyzed. The design principles and ideas of the system are introduced, and the concrete composition of the system is also introduced. The function of each part and the way of data exchange between them are analyzed in detail. In order to reduce the dependence on the browser and consider the security of the intranet, it can not connect to the Internet. 2) the design and implementation of the software platform of the vehicle monitoring system are completed, and in order to reduce the dependence on the browser, it is impossible to connect to the Internet. This platform adopts OpenLayers. API is used to develop electronic map. The paper presents its detailed implementation process, which includes three basic functions: real time monitoring, historical track playback and vehicle scheduling. In order to solve the problem that the parking time may decrease the response performance of the system during the history track playback process, the paper optimizes the trajectory data compression and obtains good results.
