【摘要】：油田通常地處偏僻、地廣人稀,并且分布廣闊,自然環(huán)境十分惡劣,這給油田的安全防護(hù)工作帶來極大的困難,發(fā)生火災(zāi)等意外時不能及時的被發(fā)現(xiàn)并制止,盜搶油田設(shè)備的現(xiàn)象時有發(fā)生。油田的生產(chǎn)活動已經(jīng)離不開視頻監(jiān)控系統(tǒng)的幫助,它可以有效的防止盜搶事件,更能幫助人們及時發(fā)現(xiàn)許多安全隱患以及在事故發(fā)生地保留可靠真實的視頻信息,保證了在生產(chǎn)工作中的安全。本文基于無線網(wǎng)橋技術(shù)、VLC技術(shù)、Linux開發(fā)技術(shù),對油田視頻監(jiān)控系統(tǒng)進(jìn)行了深入的分析。首先根據(jù)系統(tǒng)設(shè)計思想,根據(jù)用戶需求及客觀環(huán)境進(jìn)行需求分析,完成了一種基于無線網(wǎng)橋技術(shù)的油田視頻監(jiān)控系統(tǒng)的方案設(shè)計。然后,對監(jiān)控系統(tǒng)各組成部分進(jìn)行了分析與設(shè)計,包含了對視頻監(jiān)控前端的硬件選擇、各部分組合及驅(qū)動,對無線網(wǎng)絡(luò)的方案的設(shè)計,以及對監(jiān)控中心點的設(shè)計和軟件客戶端的實現(xiàn)。視頻監(jiān)控系統(tǒng)在實現(xiàn)過程中涉及到了嵌入式Linux軟件開發(fā)技術(shù)、VLC技術(shù)、mjpeg-streamer的使用、以及驅(qū)動程序的加載等技術(shù),在客戶端呈現(xiàn)了清晰的實時視頻,并且完成了對視頻的錄制工作。ONVIF,即網(wǎng)絡(luò)視頻產(chǎn)品標(biāo)準(zhǔn)網(wǎng)絡(luò)接口開放論壇,其目標(biāo)是為了實現(xiàn)完全標(biāo)準(zhǔn)化的、可互相操作的網(wǎng)絡(luò)視頻服務(wù),即使由不同網(wǎng)絡(luò)視頻供應(yīng)商組成的產(chǎn)品也可以完全互通。本文以WSDL、SOAP協(xié)議、Web Service為基礎(chǔ),對ONVIF協(xié)議開發(fā)進(jìn)行了深入的分析和理解,在Linux操作系統(tǒng)上完成了ONVIF協(xié)議設(shè)備發(fā)現(xiàn)、視頻流對接以及用戶鑒權(quán)功能的開發(fā)與測試,本文展示了在ONVIF協(xié)議的運行與測試結(jié)果。
[Abstract]:Oil fields are usually remote, sparsely populated, and widely distributed, and the natural environment is very bad. This brings great difficulties to the safety and protection of oil fields, and when accidents such as fires occur, they cannot be detected and stopped in time. Stealing and robbing oil field equipment occurs from time to time. The production activities of oil fields can not be separated from the help of video surveillance system. It can effectively prevent robberies, help people discover many security risks in time and keep reliable and real video information in the places where the accidents occur. Ensure the safety in the production work. In this paper, based on wireless bridge technology and VLC technology and Linux development technology, the oil field video monitoring system is deeply analyzed. Firstly, according to the system design idea, the requirement analysis according to the user's demand and the objective environment, the scheme design of the oil field video surveillance system based on the wireless bridge technology is completed. Then, the components of the monitoring system are analyzed and designed, including the choice of the hardware of the front end of video surveillance, the combination and drive of each part, and the design of the scheme of wireless network. And the design of monitoring center and the realization of software client. In the implementation of video surveillance system, the embedded Linux software development technology and the use of mjpeg-streamer, as well as the loading of driver, are involved in the implementation of the video monitoring system, and the clear real-time video is presented in the client. And completed the recording of video. ONVIFF, the network video product standard network interface open forum, its goal is to achieve a fully standardized, interoperable network video services, Even products made up of different network video providers can be fully interlinked. Based on the WSDL soap protocol Service, this paper makes a deep analysis and understanding of the ONVIF protocol development, and completes the development and test of the ONVIF protocol device discovery, video stream docking and user authentication function on the Linux operating system. This paper presents the running and testing results of the ONVIF protocol.
