【摘要】：近年来，随着汽车工业和定位导航、无线通信等信息技术的快速发展以及当前社会经济发展的需要，促使着智能交通系统（ITS）的产生。ITS是无线通信、定位导航、控制、地理信息系统以及计算机处理等多项先进技术的有效集成，，它的产生对有效地解决交通拥堵，提高公路通行能力，降低交通事故，提高能源利用率，治理环境污染起到了很重要的作用。GPS车辆定位系统作为智能交通系统的核心应用之一，对于它的研究具有非常重要的现实意义。论文分析了国内外GPS车辆定位监控系统现状以及通过对GPS,GIS,3G通信技术等相关关键技术的深入研究，提出了利用3G技术构建GPS车辆定位系统，并进行了总体方案设计。该系统将GPS车辆定位系统分为监控中心系统和车辆定位通讯系统两个部分，本文重点研究了监控中心的GPS监控管理平台和服务器通信中间件。GPS监控管理平台是在Microsoft Visual Studio2010开发环境下使用C#.NET和JS语言进行开发出来的，平台GIS位置服务模块的开发调用了Mapbar提供的地图数据和二次开发接口实现了车辆在Web电子地图上的定位与跟踪。服务器通信中间件是车载终端与GPS监控管理平台进行通信的桥梁，主要完成与车载终端、GPS监控管理平台的信息交互，通过服务器中间件对车辆信息采用规定协议进行了新的、统一的封装，使他们之间通信能够更加顺畅。最后在Socket通信编程的基础上提出并实现了通信服务器IOCP优化模型，它能很好地解决服务器负载的问题，有效的提高了服务器的承载能力。融合了GPS、GIS、3G、数据库技术和计算机数据处理技术的GPS车辆定位系统，提高了对车辆的实时定位、信息传输、监控和管理的稳定性和可靠性，成功的实现了系统的预定目标。经测试，系统性能稳定。目前，该系统已在企业或政府公派车辆、物流、出租等行业成功应用。
[Abstract]:In recent years, with the rapid development of information technology, such as automobile industry and positioning navigation, wireless communication and the need of social and economic development, the production of Intelligent Transportation system (its) is wireless communication, positioning navigation, control. The effective integration of many advanced technologies, such as geographic information system and computer processing, can effectively solve traffic congestion, improve highway traffic capacity, reduce traffic accidents and improve energy efficiency. As one of the core applications of intelligent transportation system, GPS vehicle positioning system has a very important practical significance for its research. This paper analyzes the current situation of GPS vehicle positioning and monitoring system at home and abroad, and through the in-depth study of the key technologies, such as 3G communication technology, puts forward the construction of GPS vehicle positioning system using 3G technology. The GPS vehicle positioning system is divided into two parts: the monitoring center system and the vehicle positioning communication system. This paper focuses on the GPS monitoring and management platform and server communication middleware. GPS-based monitoring and management platform is developed by using C#.NET and JS language in the Microsoft Visual Studio2010 development environment. The development of the platform GIS location service module calls the map data provided by Mapbar and the secondary development interface to realize the location and tracking of vehicles on the Web electronic map. The server communication middleware is the vehicle terminal and GPS monitor and management platform. Bridges for communication, It mainly completes the information interaction with the vehicle terminal GPS monitoring and management platform, and adopts a new and unified encapsulation of the vehicle information through server middleware. Finally, the communication server IOCP optimization model is proposed and implemented on the basis of Socket communication programming, which can solve the problem of server load and effectively improve the load capacity of the server. The GPS vehicle positioning system, which integrates GPS / GIS 3G, database technology and computer data processing technology, improves the stability and reliability of real-time positioning, information transmission, monitoring and management of vehicles. The system has been tested and tested, and the system has been successfully applied in enterprises or government enterprises, such as public vehicles, logistics, rental and other industries.
