【摘要】：近年來，隨著汽車工業(yè)和定位導(dǎo)航、無線通信等信息技術(shù)的快速發(fā)展以及當(dāng)前社會經(jīng)濟(jì)發(fā)展的需要，促使著智能交通系統(tǒng)（ITS）的產(chǎn)生。ITS是無線通信、定位導(dǎo)航、控制、地理信息系統(tǒng)以及計算機(jī)處理等多項先進(jìn)技術(shù)的有效集成，，它的產(chǎn)生對有效地解決交通擁堵，提高公路通行能力，降低交通事故，提高能源利用率，治理環(huán)境污染起到了很重要的作用。GPS車輛定位系統(tǒng)作為智能交通系統(tǒng)的核心應(yīng)用之一，對于它的研究具有非常重要的現(xiàn)實意義。 論文分析了國內(nèi)外GPS車輛定位監(jiān)控系統(tǒng)現(xiàn)狀以及通過對GPS,GIS,3G通信技術(shù)等相關(guān)關(guān)鍵技術(shù)的深入研究，提出了利用3G技術(shù)構(gòu)建GPS車輛定位系統(tǒng)，并進(jìn)行了總體方案設(shè)計。該系統(tǒng)將GPS車輛定位系統(tǒng)分為監(jiān)控中心系統(tǒng)和車輛定位通訊系統(tǒng)兩個部分，本文重點(diǎn)研究了監(jiān)控中心的GPS監(jiān)控管理平臺和服務(wù)器通信中間件。GPS監(jiān)控管理平臺是在Microsoft Visual Studio2010開發(fā)環(huán)境下使用C#.NET和JS語言進(jìn)行開發(fā)出來的，平臺GIS位置服務(wù)模塊的開發(fā)調(diào)用了Mapbar提供的地圖數(shù)據(jù)和二次開發(fā)接口實現(xiàn)了車輛在Web電子地圖上的定位與跟蹤。服務(wù)器通信中間件是車載終端與GPS監(jiān)控管理平臺進(jìn)行通信的橋梁，主要完成與車載終端、GPS監(jiān)控管理平臺的信息交互，通過服務(wù)器中間件對車輛信息采用規(guī)定協(xié)議進(jìn)行了新的、統(tǒng)一的封裝，使他們之間通信能夠更加順暢。最后在Socket通信編程的基礎(chǔ)上提出并實現(xiàn)了通信服務(wù)器IOCP優(yōu)化模型，它能很好地解決服務(wù)器負(fù)載的問題，有效的提高了服務(wù)器的承載能力。 融合了GPS、GIS、3G、數(shù)據(jù)庫技術(shù)和計算機(jī)數(shù)據(jù)處理技術(shù)的GPS車輛定位系統(tǒng)，提高了對車輛的實時定位、信息傳輸、監(jiān)控和管理的穩(wěn)定性和可靠性，成功的實現(xiàn)了系統(tǒng)的預(yù)定目標(biāo)。經(jīng)測試，系統(tǒng)性能穩(wěn)定。目前，該系統(tǒng)已在企業(yè)或政府公派車輛、物流、出租等行業(yè)成功應(yīng)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.
