【摘要】：高速公路視頻監(jiān)控系統(tǒng)對于管理人員快速發(fā)現(xiàn)各種異常情況,并迅速有效的進(jìn)行處理,確保道路暢通,起著至關(guān)重要的作用。天津的各條高速公路正在陸續(xù)實(shí)現(xiàn)全路全程無盲點(diǎn)視頻監(jiān)控,管理者在監(jiān)控中心就能掌握境內(nèi)高速的路況信息。隨著移動(dòng)互聯(lián)網(wǎng)以及流媒體技術(shù)的不斷發(fā)展,將匯集至信息中心的視頻監(jiān)控信息及時(shí)延伸發(fā)布至授權(quán)移動(dòng)終端,對于緊急特情的及時(shí)處置,已十分必要。課題以天津市高速公路監(jiān)控系統(tǒng)為依托,提出了面向移動(dòng)終端的天津高速公路視頻監(jiān)控系統(tǒng)升級(jí)設(shè)計(jì)方案;經(jīng)過對主流編碼方式以及流媒體平臺(tái)的研究,采用H.264標(biāo)準(zhǔn)對原有MPEG-2系統(tǒng)進(jìn)行了硬件架構(gòu)升級(jí),以適應(yīng)流媒體播放的要求;完成了軟件架構(gòu)設(shè)計(jì)及功能模塊設(shè)計(jì)與開發(fā)工作;并完成了系統(tǒng)調(diào)試及測試工作。目前,系統(tǒng)已成功部署,運(yùn)行穩(wěn)定一年有余,實(shí)現(xiàn)了授權(quán)管理人員通過移動(dòng)終端對路況監(jiān)控信息的隨時(shí)訪問,在應(yīng)急指揮調(diào)度中發(fā)揮了重要作用。
[Abstract]:Expressway video surveillance system is very important for managers to find out all kinds of abnormal situations quickly and effectively to ensure the smooth flow of roads. Every highway in Tianjin is realizing the video surveillance without blind spot in the whole road, and the manager can master the information of the highway condition in the monitoring center. With the development of mobile Internet and streaming media technology, it is necessary to release video surveillance information gathered to information center to authorized mobile terminal. Based on Tianjin Expressway Monitoring system, this paper puts forward an upgrade design scheme of Tianjin Expressway Video Surveillance system for mobile terminal, through the research of mainstream coding method and streaming media platform, The hardware architecture of the original MPEG-2 system is upgraded to meet the requirements of streaming media playing, the software architecture design and function module design and development are completed, and the system debugging and testing work is completed. At present, the system has been successfully deployed and has been running steadily for more than a year. The authorized managers can access the monitoring information of road condition through mobile terminals at any time, which plays an important role in emergency command and dispatch.
