【正文】 論文題目： 公交 車 管理系統(tǒng)車載終端 設(shè)計(jì) 摘 要 本文主要闡述了一種智能公交管理系統(tǒng) (ITS)的車載終端的設(shè)計(jì)方法。所謂智能公交通管理系統(tǒng) ,就是在公交網(wǎng)絡(luò)分配、公交調(diào)度、預(yù)測(cè)算法等關(guān)鍵理論研究的前提下，利用系統(tǒng)工程的理論和方法，將現(xiàn)代通信、信息、電子、控制、計(jì)算機(jī)、網(wǎng)絡(luò)、定位技術(shù)、 GIS 等新技術(shù)集成應(yīng)用于公共交通系統(tǒng)，通過構(gòu)建現(xiàn)代的信息管理系統(tǒng)和控制調(diào)度模式，實(shí)現(xiàn)公共交通調(diào)度、運(yùn)營(yíng)、管理的信息化、現(xiàn)代化和智能化，增強(qiáng)公交企業(yè)管理水平和服務(wù)水平，提高公交企業(yè)的運(yùn)營(yíng)效率和效益；同時(shí)為出行者提供更加安全、舒服、便捷 的公共交通信息 服務(wù)。而車載終端設(shè)備作為實(shí)現(xiàn)該系統(tǒng)的關(guān)鍵設(shè)備，可以實(shí)現(xiàn)車輛位置信息的讀取，車輛運(yùn)行狀況記錄，自動(dòng)報(bào)站以及 車輛與管理站的無線 通信 等功能 。 關(guān)鍵詞 ： 定位技術(shù) ， 智能公交管理系統(tǒng)，車載終端 A design about automotive terminal in Intelligent Transportation management System Abstract This paper described a design method about automotive terminal in Intelligent Transportation management System (ITS). The socalled Intelligent public Traffic management System is based on such key theoretical research as the allocation of public transport work, bus scheduling, prediction algorithms and use of Systems Engineering Methods of modern munications, information, electronics, control, puter, working, positioning technology, GIS and other new technologies in the Public Transport System, Then ,build a modern Information Management Systems and Control Transfer Scheduling mode to achieve a informational, modern, intelligent public transport’s scheduling, operation and management, In order to enhance public enterprise management and service level, to improve public transport enterprises operating efficiency and effectiveness, At the same time provide a more safe, fortable, convenient public transportation service in information. The car terminal device as a key equipment of the system, mainly have following functions: to read the vehicle positioning information, vehicle operating conditions record, automatic reporting stop station, realizing wireless munication between Management station and vehicle.
