【摘要】：城市智能交通誘導(dǎo)系統(tǒng)的基礎(chǔ)是交通數(shù)據(jù)信息的采集,本文從多個(gè)角度對(duì)交通數(shù)據(jù)采集做了介紹。交通管控平臺(tái)作為一個(gè)中央控制系統(tǒng),通過數(shù)據(jù)采集系統(tǒng)進(jìn)行數(shù)據(jù)的收集,并對(duì)數(shù)據(jù)進(jìn)行加工、處理、分析,使采集到的交通數(shù)據(jù)轉(zhuǎn)換成多源異構(gòu)資料,并對(duì)數(shù)據(jù)資料進(jìn)行相關(guān)的標(biāo)準(zhǔn)化處理后存儲(chǔ)。利用多種智能交通算法處理收集來的信息形成用來決策交通誘導(dǎo)系統(tǒng)的數(shù)據(jù),將這些數(shù)據(jù)以XML的形式進(jìn)行封裝并通過Apache ActiveMQ進(jìn)行傳輸,傳輸?shù)椒⻊?wù)器協(xié)議轉(zhuǎn)換軟件中,服務(wù)器轉(zhuǎn)換軟件進(jìn)行分析處理之后做出對(duì)應(yīng)的控制卡操作動(dòng)作,最后在終端LED屏幕上進(jìn)行誘導(dǎo)顯示。本文著重介紹了顯示系統(tǒng)和服務(wù)器轉(zhuǎn)換軟件的設(shè)計(jì)。交通誘導(dǎo)顯示終端是由誘導(dǎo)顯示控制模塊、誘導(dǎo)顯示終端設(shè)備、電源設(shè)備、箱體等組成。交通誘導(dǎo)信息顯示控制板用來控制整個(gè)誘導(dǎo)顯示終端,通過接收管控平臺(tái)發(fā)出來的報(bào)文信息去實(shí)時(shí)的在誘導(dǎo)顯示終端上顯示誘導(dǎo)信息,該控制系統(tǒng)具備遠(yuǎn)程發(fā)布播放列表,遠(yuǎn)程監(jiān)控播放內(nèi)容以及屏體狀態(tài)、遠(yuǎn)程控制播放狀態(tài)。系統(tǒng)支持各種網(wǎng)絡(luò)環(huán)境,包括互聯(lián)網(wǎng)、城域網(wǎng)以及局域網(wǎng)等,并且支持各種有線寬帶接入方式和無線寬帶接入方式。監(jiān)控以及遠(yuǎn)程開關(guān)機(jī)功能用多功能卡進(jìn)行附加實(shí)現(xiàn)。由P18模組構(gòu)成的全彩LED戶外屏作為顯示終端設(shè)備。服務(wù)器協(xié)議轉(zhuǎn)換軟件的設(shè)計(jì),首先解析了轉(zhuǎn)換軟件的需求,闡述了管控平臺(tái)是通過ActiveMQ將數(shù)據(jù)傳輸給轉(zhuǎn)換軟件,介紹了ActiveMQ的一些基本內(nèi)容,羅列了重要的數(shù)據(jù)結(jié)構(gòu),并對(duì)重要的模塊,例如報(bào)文解析中的節(jié)目單管理報(bào)文分析模塊做了詳細(xì)的介紹,因?yàn)閳?bào)文是XML格式的,所以開始解釋了如何分析XML文件。接著利用C#的XmlDocument解析了報(bào)文文件,并詳細(xì)的闡述了如何實(shí)現(xiàn)這個(gè)報(bào)文進(jìn)行發(fā)送。在監(jiān)聽數(shù)據(jù)模塊中,首先解釋了windows消息的機(jī)制,并通過這個(gè)機(jī)制實(shí)現(xiàn)了監(jiān)聽數(shù)據(jù)模塊。該系統(tǒng)已經(jīng)在青島實(shí)際使用,誘導(dǎo)顯示系統(tǒng)支持精細(xì)化判別交通狀態(tài),可區(qū)分通暢(綠色)、緩慢(黃色)、擁堵(紅色)3種狀態(tài),判別周期≤5分鐘。輔以人工采編等多種手段,還能為用戶提供各類交通事件的實(shí)時(shí)處理進(jìn)展。其服務(wù)手段豐富多樣：針對(duì)不同交通出行者、交通管理者的綜合信息服務(wù)平臺(tái),可以采取多種信息服務(wù)手段,發(fā)布各類交通參數(shù)(擁堵程度、旅行時(shí)間、事故信息、交通管制信息、氣象信息等),發(fā)布內(nèi)容實(shí)時(shí)改變的自適應(yīng)交通信息發(fā)布手段,提高交通信息發(fā)布內(nèi)容的有效性,幫助出行者選擇最佳出行路線,從而達(dá)到最優(yōu)的路網(wǎng)負(fù)載均衡,方便市民出行。
[Abstract]:The basis of urban intelligent traffic guidance system is the collection of traffic data. This paper introduces traffic data collection from several angles. Traffic control platform as a central control system. Through the data acquisition system to collect data, and data processing, processing, analysis, so that the collected traffic data into multi-source heterogeneous data. And the data are stored after standardized processing. The information collected is processed by a variety of intelligent transportation algorithms to form the data used to make decision on traffic guidance system. The data is encapsulated in the form of XML and transmitted through Apache ActiveMQ to the server protocol conversion software. After the server conversion software analysis and processing, the corresponding control card operation action is made. Finally, the paper introduces the design of the display system and server conversion software on the terminal LED screen. The traffic guidance display terminal is controlled by the guidance display module and the inductive display terminal equipment. The traffic guidance information display control board is used to control the whole induction display terminal, through receiving the message information sent out from the control platform to display the guidance information on the induced display terminal in real time. The control system has remote release playlist, remote monitoring of playback content and screen status, remote control of playback status. The system supports a variety of network environments, including the Internet, man and LAN. It also supports various wired broadband access modes and wireless broadband access modes. Monitoring and remote switching machine functions are implemented with multi-function cards. Full-color LED outdoor screen composed of P18 modules is used as display terminal. Equipment. Design of server protocol conversion software. First of all, the requirements of the conversion software are analyzed, the management and control platform is to transfer data to the conversion software through ActiveMQ, and some basic contents of ActiveMQ are introduced. The important data structures are listed, and the important modules, such as program management message analysis module in message parsing, are introduced in detail, because the message is in XML format. So I began to explain how to parse the XML file. Then I parsed the message file with the XmlDocument of C #. In the monitoring data module, the mechanism of windows message is first explained. The system has already been used in Qingdao. The inductive display system supports fine identification of traffic state and can distinguish smooth (green, slow (yellow)). Congestion (red) 3 states, discrimination period 鈮，
