【摘要】:近幾年,隨著中國經(jīng)濟(jì)的迅速騰飛,汽車保有量突飛猛進(jìn),智能交通已經(jīng)成為國內(nèi)交通運(yùn)輸行業(yè)迫在眉睫需要解決的課題。智能交通的突出特點(diǎn)是通過對信息的收集、處理、發(fā)布、交換、分析和利用,根據(jù)交通參與者的需求提供各種所需的服務(wù);谥悄芙煌ǖ能嚶(lián)網(wǎng)管理系統(tǒng)是智能交通的核心,車聯(lián)網(wǎng)管理系統(tǒng)為千變?nèi)f化的道路交通提供專業(yè)、可靠和實時的數(shù)據(jù)。為未來智能交通的普及打好基礎(chǔ)。本文實現(xiàn)的車聯(lián)網(wǎng)系統(tǒng)采用了無線通信技術(shù)、GPS全球衛(wèi)星定位技術(shù)、GIS地理信息技術(shù)、計算機(jī)網(wǎng)絡(luò)技術(shù)和數(shù)據(jù)庫技術(shù)等,建立了一個GPS監(jiān)控中心和可以通過各種設(shè)備使用互聯(lián)網(wǎng)接入的綜合的道路衛(wèi)星車輛衛(wèi)星定位系統(tǒng)平臺。本系統(tǒng)由五部分組成:包括GPS監(jiān)控中心、無線通信平臺、全球衛(wèi)星定位系統(tǒng)、車載定位設(shè)備和道路衛(wèi)星車輛衛(wèi)星定位系統(tǒng)平臺。本系統(tǒng)的總體架構(gòu)分為六層,分別為:應(yīng)用展示、應(yīng)用服務(wù)、基礎(chǔ)服務(wù)、數(shù)據(jù)存儲、數(shù)據(jù)處理和數(shù)據(jù)接收。數(shù)據(jù)接收層負(fù)責(zé)接收從終端發(fā)來的各種數(shù)據(jù),并下達(dá)指令和數(shù)據(jù)到終端上,提供雙向通訊服務(wù)。數(shù)據(jù)接收層提供幾種方式的數(shù)據(jù)接入,比如終端直連、短信指令下發(fā)等。終端接收到數(shù)據(jù)后,把數(shù)據(jù)插入系統(tǒng)的消息隊列。同時,數(shù)據(jù)接收層還需要處理由系統(tǒng)下發(fā)給終端的各種指令以及數(shù)據(jù)。如果直連失敗,可以通過短信進(jìn)行指令的派發(fā)。數(shù)據(jù)處理層負(fù)責(zé)從消息隊列中讀取從終端接收的數(shù)據(jù),進(jìn)行協(xié)議的解析、數(shù)據(jù)處理,存入數(shù)據(jù)庫。數(shù)據(jù)存儲層含兩個數(shù)據(jù)庫,一個是關(guān)系型數(shù)據(jù)庫,一個是非結(jié)構(gòu)化數(shù)據(jù)庫。關(guān)系型數(shù)據(jù)庫用于存儲關(guān)系型基礎(chǔ)數(shù)據(jù)、業(yè)務(wù)數(shù)據(jù)和地理空間數(shù)據(jù)。非結(jié)構(gòu)化數(shù)據(jù)庫用于存儲非結(jié)構(gòu)化數(shù)據(jù):視頻、圖片和軌跡等;A(chǔ)服務(wù)層負(fù)責(zé)向應(yīng)用服務(wù)層提供公共的構(gòu)件和服務(wù),比如報表打印服務(wù)、角色權(quán)限管理、多媒體服務(wù)、電子地圖服務(wù)和系統(tǒng)管理服務(wù);A(chǔ)服務(wù)層獨(dú)立開發(fā)與升級,保證接口的延續(xù)性與擴(kuò)展性。應(yīng)用服務(wù)層負(fù)責(zé)系統(tǒng)的業(yè)務(wù)管理,并給外部系統(tǒng)提供共享數(shù)據(jù)的接口,還提供統(tǒng)一的身份認(rèn)證。應(yīng)用服務(wù)層的系統(tǒng)管理功能,可以管理下屬各級分公司的車輛,系統(tǒng)提供各種類型的監(jiān)控、查詢查看和統(tǒng)計分析等功能。應(yīng)用展示層提供瀏覽器、桌面客戶端、WAP瀏覽器等多種用戶界面,滿足各類用戶使用不同的設(shè)備進(jìn)行管理和查看。本系統(tǒng)技術(shù)上主要涉及兩個方面:對于并發(fā)量小、實時性不高的監(jiān)控管理系統(tǒng):采用B/S架構(gòu),開發(fā)語言使用Java;使用分布式業(yè)務(wù)中間件部署;提供線性擴(kuò)展;獨(dú)立的電子地圖服務(wù),可以通過API的方式進(jìn)行調(diào)用。對于并發(fā)量大,可以處理海量數(shù)據(jù)的通訊接收機(jī),此系統(tǒng)處理與車載終端間的數(shù)據(jù)通信:采用C/S架構(gòu),開發(fā)語言使用C#和C++;數(shù)據(jù)分為關(guān)系型數(shù)據(jù)和非關(guān)系型數(shù)據(jù),非關(guān)系型數(shù)據(jù)采用結(jié)構(gòu)化存儲方案;建立模擬終端,可以進(jìn)行并行測試。本系統(tǒng)運(yùn)用了SOA面向服務(wù)的體系結(jié)構(gòu)來實現(xiàn)車聯(lián)網(wǎng)的概念。結(jié)合SOA技術(shù)和車聯(lián)網(wǎng)系統(tǒng)的具體需求,設(shè)計并構(gòu)建適用于車聯(lián)網(wǎng)系統(tǒng)的SOA應(yīng)用模型,并進(jìn)行具體模塊的建模和分解。通過終端視頻可以實現(xiàn)遠(yuǎn)程調(diào)用,通過構(gòu)建流媒體服務(wù)器,可以實現(xiàn)實時查看視頻監(jiān)控。本系統(tǒng)旨在通過對智能交通的概念、SOA面向服務(wù)體系結(jié)構(gòu)的研究,深入挖掘行業(yè)需求,例如公交、物流、出租、租賃車、危品車、押運(yùn)車等各種行業(yè)車輛,提供一套基于智能交通的車聯(lián)網(wǎng)管理系統(tǒng)設(shè)計方案,并賦予實施。本系統(tǒng)采用無線通信技術(shù)、GPS全球衛(wèi)星定位技術(shù)、GIS技術(shù)、計算機(jī)網(wǎng)絡(luò)技術(shù)和數(shù)據(jù)庫技術(shù)等,建立一個GPS監(jiān)控中心、用戶可以通過互聯(lián)網(wǎng)接入的綜合性道路衛(wèi)星車輛衛(wèi)星定位系統(tǒng)平臺。本系統(tǒng)對各種終端,通信方式,數(shù)據(jù)交換標(biāo)準(zhǔn),系統(tǒng)的可靠性以及穩(wěn)定易用性也做了很多探索和嘗試,力求推出一個適應(yīng)性高,穩(wěn)定性強(qiáng),可靠易用的綜合性車聯(lián)網(wǎng)管理系統(tǒng)。
[Abstract]:In recent years, with the rapid development of China's economy and the rapid development of car ownership, intelligent transportation has become an urgent problem to be solved in the domestic transportation industry. The prominent feature of intelligent transportation is to provide all kinds of needs according to the needs of traffic participants through the collection, processing, release, exchange, analysis and utilization of information. The network management system based on intelligent traffic is the core of intelligent traffic. The network management system provides professional, reliable and real-time data for the ever-changing road traffic. It provides a good basis for the popularization of intelligent traffic in the future. This system adopts wireless communication technology, GPS global satellite positioning technology, GIS Information technology, computer network technology and database technology have established a GPS monitoring center and a comprehensive satellite positioning system platform for road satellite vehicles which can be connected through various devices. The system consists of five parts: GPS monitoring center, line free communication platform, global satellite positioning system, vehicle positioning The overall architecture of this system is divided into six layers: application display, application service, basic service, data storage, data processing and data receiving. The data receiving layer is responsible for receiving all kinds of data from the terminal, and providing instruction and data to the terminal, providing two-way communication service. The data receiving layer provides data access in several ways, such as the direct connection of the terminal, the sending of messages, and so on. The terminal receives the data and inserts the data into the message queue of the system. At the same time, the data receiving layer also needs to deal with the various instructions and data sent to the terminal by the system. If the direct connection fails, the instructions can be sent through SMS. The data processing layer is responsible for reading the data received from the terminal from the message queue, analyzing the protocol, processing the data, and storing it into the database. The data storage layer contains two databases, one is a relational database and the other is an unstructured database. The relational database is used to store the relational basic data, the business data and the number of geographical spaces. Unstructured database is used to store unstructured data: video, pictures, and trajectories. The basic service layer is responsible for providing public components and services to the application service layer, such as report print service, role management, multimedia service, electronic map service and system management. The basic service layer is independently developed and upgraded to guarantee the connection. The application service layer is responsible for the business management of the system, provides the interface to the external system, and provides the unified identity authentication. The system management function of the application service layer can manage the vehicles of the subordinate branches at all levels, and the system provides various types of monitoring, inquiry and statistical analysis and other functions. The application display layer provides a variety of user interfaces, such as browsers, desktop clients, WAP browsers and so on, to meet various users' use of different devices for management and view. This system is mainly involved in two aspects: the monitoring management system with small concurrency and low real time: using B/S architecture, developing language using Java; using distributed industry. Service middleware deployment; providing linear extension; independent electronic map service can be invoked in the way of API. For large concurrency, a communication receiver that can handle mass data, the system handles data communication with the vehicle terminal: using the C/S architecture, developing the language using C# and C++; data is divided into relational data and non relational data Data, non relational data are structured storage scheme, and the simulation terminal can be built to carry out parallel testing. This system uses SOA service oriented architecture to realize the concept of car networking. It designs and constructs a SOA application model which is suitable for the car networking system, and carries out a specific model. Through the construction of the streaming media server, the video monitoring can be realized through the construction of the streaming media server. This system aims to dig into the industry requirements through the concept of intelligent traffic, SOA oriented service architecture, such as bus, logistics, rental, rental car, dangerous goods car, escort car. And other industry vehicles, provide a set of intelligent traffic based vehicle network management system design scheme, and give implementation. This system uses wireless communication technology, GPS global positioning technology, GIS technology, computer network technology and database technology, to establish a GPS monitoring center, the user can access the comprehensive road through the Internet. The satellite vehicle satellite positioning system platform. This system has also made a lot of explorations and attempts on various terminals, communication mode, data exchange standard, system reliability and stability and ease of use, and strives to introduce a comprehensive network management system with high adaptability, strong stability, reliable and easy to use.
