【摘要】：隨著我國經(jīng)濟的飛速發(fā)展，汽車數(shù)量也逐年增加，隨之出現(xiàn)的交通問題也日益嚴重。車輛遠程監(jiān)控系統(tǒng)是智能交通系統(tǒng)（ITS）的核心部分之一，可以對車輛的出行進行規(guī)劃，提高道路的利用率，改善交通環(huán)境；可以對車輛進行實時監(jiān)控，及時發(fā)現(xiàn)車輛故障，盡可能避免交通事故的發(fā)生，增強行車安全等。本課題是在重慶產(chǎn)學研合作創(chuàng)新項目“重慶恒通新能源客車遠程監(jiān)控系統(tǒng)開發(fā)”和國家重點實驗室專向經(jīng)費項目的支持下對車輛遠程監(jiān)控系統(tǒng)進行了深入的研究。 首先，了解GPS車輛監(jiān)控導航系統(tǒng)在國內(nèi)外的發(fā)展狀況，通過分析其總體構架、、軟硬件設備、工作原理以及功能模塊，挖掘現(xiàn)有車輛監(jiān)控導航系統(tǒng)中存在的不足，從而提出了一種以手機作為車載數(shù)采終端的車輛遠程監(jiān)控系統(tǒng)的方案，該方案基于Android手機操作系統(tǒng)，利用3G網(wǎng)絡實現(xiàn)數(shù)據(jù)通訊，然后監(jiān)控中心服務器將上傳的數(shù)據(jù)進行分析、處理，實現(xiàn)對目標車輛的實時監(jiān)控、歷史軌跡回放、車輛報警等功能。 第二，深入剖析車輛遠程監(jiān)控系統(tǒng)所需的關鍵技術，即：Android系統(tǒng)、地理信息系統(tǒng)（GIS）、全球定位系統(tǒng)（GPRS）、3G無線通信技術等。根據(jù)這些關鍵技術的工作原理設計出本系統(tǒng)的總體架構，并設計了監(jiān)控系統(tǒng)各個模塊要實現(xiàn)的功能。 第三，基于提出的系統(tǒng)總體方案，設計并建立了系統(tǒng)的軟硬件架構。采用Android智能手機、ELM327、車輛OBD系統(tǒng)的集成為一個車載終端采集車輛動態(tài)數(shù)據(jù)，從而實現(xiàn)了用專用設備作為數(shù)據(jù)采集終端的弊端。并采用B/S架構搭建監(jiān)控中心服務器，完成對上傳數(shù)據(jù)的接收和解析，同時，選用J2EE作為軟件開發(fā)平臺，采用MVC模式進行整個系統(tǒng)的軟件開發(fā)，實現(xiàn)了整個系統(tǒng)的模塊化，便于系統(tǒng)的維護升級。 第四，選用SQL Server2005進行系統(tǒng)中心數(shù)據(jù)庫的開發(fā)，根據(jù)系統(tǒng)的數(shù)據(jù)需要，完成了系統(tǒng)中心數(shù)據(jù)庫的概念模型設計、邏輯設計和數(shù)據(jù)庫的物理實現(xiàn)，實現(xiàn)了系統(tǒng)后臺數(shù)據(jù)的存取，使整個系統(tǒng)的數(shù)據(jù)管理更加信息化和科學化。 第五，，結合車輛遠程監(jiān)控系統(tǒng)的功能需求編程實現(xiàn)各個功能模塊，根據(jù)人機交互的特性開發(fā)系統(tǒng)的界面，方便用戶對本系統(tǒng)的操作。最后，對本系統(tǒng)進行了實車聯(lián)調(diào)測試，完成系統(tǒng)軟硬件的配置，實現(xiàn)車載數(shù)據(jù)的無線傳輸和實時采集、監(jiān)控中心的數(shù)據(jù)解析以及行車軌跡顯示等功能。
[Abstract]:With the rapid development of China's economy, the number of cars is increasing year by year, and the traffic problems are becoming more and more serious. Vehicle remote monitoring system is one of the core parts of Intelligent Transportation system (ITS), which can plan the travel of vehicles, improve the utilization of roads and improve the traffic environment. It can monitor the vehicle in real time, find the vehicle fault in time, avoid the traffic accident as far as possible, and enhance the safety of the vehicle. Under the support of Chongqing industry, university, research and innovation project "Chongqing Hengtong New Energy bus remote Monitoring system Development" and the special fund project of the State key Laboratory, the vehicle remote monitoring system has been deeply studied in this paper. First of all, understand the development of GPS vehicle monitoring and navigation system at home and abroad, through the analysis of its overall structure, hardware and software equipment, working principles and functional modules, mining the existing vehicle monitoring and navigation system shortcomings. A scheme of vehicle remote monitoring system based on mobile phone is put forward. This scheme is based on Android mobile phone operating system, realizes data communication by using 3G network, and then analyzes the data uploaded by the monitoring center server. Process, realize the target vehicle real-time monitoring, historical track playback, vehicle alarm and other functions. Secondly, the key technologies of vehicle remote monitoring system are analyzed, such as Android system, (GIS), Global Positioning system (GIS), 3G wireless communication technology, etc. According to the working principle of these key technologies, the overall architecture of the system is designed, and the functions to be realized by each module of the monitoring system are designed. Thirdly, the hardware and software architecture of the system is designed and built based on the overall scheme. With Android smart phone, the ELM327, vehicle OBD system is integrated into a vehicle terminal to collect vehicle dynamic data, thus realizing the malpractice of using special equipment as data acquisition terminal. At the same time, J2EE is chosen as the software development platform and MVC mode is used to develop the software of the whole system, which realizes the modularization of the whole system. Easy to maintain and upgrade the system. Fourthly, SQL Server2005 is selected to develop the central database of the system. According to the data requirement of the system, the conceptual model design, logic design and physical realization of the database are completed, and the access of the background data of the system is realized. Make the data management of the whole system more information and scientific. Fifthly, combined with the functional requirements of the vehicle remote monitoring system programming to achieve each functional module, according to the characteristics of human-computer interaction development of the system interface, convenient for users to the system operation. Finally, the system is tested, the hardware and software of the system are configured, the wireless transmission and real-time acquisition of the vehicle data, the data analysis of the monitoring center and the display of the driving track are realized.
