【摘要】：現(xiàn)如今的科技社會(huì)中,隨著網(wǎng)絡(luò)科技的不斷進(jìn)步,視頻監(jiān)控系統(tǒng)已經(jīng)得到廣泛應(yīng)用。社會(huì)對(duì)于安全的需求也隨著社會(huì)的變革不斷增加,人們對(duì)于視頻監(jiān)控系統(tǒng)的需求量也與日俱增,于是移動(dòng)視頻監(jiān)控系統(tǒng)應(yīng)運(yùn)而生�；诋�(dāng)下最流行的Linux系統(tǒng)和3G網(wǎng)絡(luò),本論文將設(shè)計(jì)一款易于使用和推廣的移動(dòng)視頻監(jiān)控系統(tǒng)。 本文通過(guò)對(duì)目前視頻監(jiān)控系統(tǒng)的市場(chǎng)需求以及發(fā)展趨勢(shì)的分析,結(jié)合理論實(shí)際可操作性,提出了一種基于嵌入式Linux系統(tǒng)的視頻監(jiān)控系統(tǒng)。該移動(dòng)視頻監(jiān)控系統(tǒng)以ARM11作為處理器,利用Linux操作系統(tǒng)、3G網(wǎng)絡(luò),實(shí)現(xiàn)了移動(dòng)視頻監(jiān)控系統(tǒng)的體積小,機(jī)動(dòng)性強(qiáng)等特點(diǎn),可以隨意安裝在各種小型房屋或其他空間內(nèi),因?yàn)?G網(wǎng)絡(luò)是移動(dòng)通信網(wǎng)絡(luò),所以甚至可以作為車(chē)載監(jiān)控系統(tǒng),隨時(shí)隨地向用戶(hù)顯示車(chē)內(nèi)情況。該系統(tǒng)的用戶(hù)端可以采用多種終端,即用戶(hù)可以通過(guò)多種方式觀察服務(wù)器端采集到并傳輸過(guò)來(lái)的視頻數(shù)據(jù),例如PC機(jī)、當(dāng)前流行的各種Android系統(tǒng)的手機(jī)客戶(hù)端、平板電腦等等,將來(lái)也可以實(shí)現(xiàn)多個(gè)終端同時(shí)使用,觀察攝像頭采集的視頻畫(huà)面。鑒于Linux系統(tǒng)良好的擴(kuò)展性和開(kāi)放性,該系統(tǒng)可以很方便的進(jìn)行規(guī)�；a(chǎn)。 本文詳細(xì)介紹了移動(dòng)視頻監(jiān)控系統(tǒng)的定義,概述了其背景以及發(fā)展過(guò)程,根據(jù)其現(xiàn)狀、監(jiān)控技術(shù)的理論知識(shí)提出了系統(tǒng)的未來(lái)發(fā)展趨勢(shì)和研究方向。本設(shè)計(jì)的功能實(shí)現(xiàn)過(guò)程為首先由USB攝像頭采集視頻數(shù)據(jù)存儲(chǔ)到Linux系統(tǒng)的服務(wù)器端,然后服務(wù)器端對(duì)視頻數(shù)據(jù)進(jìn)行M-JPEG壓縮編碼,再通過(guò)3G網(wǎng)絡(luò)實(shí)時(shí)的傳輸給客戶(hù)端,客戶(hù)端會(huì)將接收到的視頻數(shù)據(jù)顯示給用戶(hù),用戶(hù)可以實(shí)時(shí)的觀察到攝像頭端采集來(lái)的視頻數(shù)據(jù)。所以本設(shè)計(jì)將由四部分組成,即視頻數(shù)據(jù)采集終端(USB攝像頭)、視頻服務(wù)器端(ARM11開(kāi)發(fā)板Linux系統(tǒng))、傳輸網(wǎng)絡(luò)(3G)、客戶(hù)機(jī)(PC和Android手機(jī))。其中視頻服務(wù)器端所負(fù)責(zé)的視頻壓縮編碼功能采用的是M-JPEG編碼,以達(dá)到通過(guò)3G網(wǎng)絡(luò)實(shí)時(shí)傳輸對(duì)視頻數(shù)據(jù)的要求。 本文提出了完整的系統(tǒng)總體設(shè)計(jì)方案,然后從平臺(tái)搭建及驅(qū)動(dòng)移植、各個(gè)部分的應(yīng)用軟件設(shè)計(jì)兩個(gè)方面詳細(xì)介紹了移動(dòng)視頻監(jiān)控系統(tǒng)如何實(shí)現(xiàn),并且對(duì)系統(tǒng)進(jìn)行了測(cè)試和結(jié)果總結(jié)。在文章的最后對(duì)全文做出了總結(jié),并對(duì)本設(shè)計(jì)的發(fā)展和后續(xù)開(kāi)發(fā)提出了設(shè)計(jì)和想法。
[Abstract]:Nowadays, with the progress of network science and technology, video surveillance system has been widely used. The demand for security is also increasing with the change of society, and the demand for video surveillance system is also increasing, so mobile video surveillance system emerges as the times require. Based on the most popular Linux system and 3G network, this paper will design a mobile video surveillance system which is easy to use and popularize. Based on the analysis of the market demand and development trend of the current video surveillance system, a video surveillance system based on embedded Linux system is proposed in this paper, which is feasible in theory and practice. The mobile video surveillance system uses ARM11 as the processor and uses the Linux operating system to realize the characteristics of small size and strong mobility, and can be installed in various small houses or other space. Because 3G network is a mobile communication network, it can even be used as a vehicle monitoring system to display the situation of the vehicle to the user anytime and anywhere. The client side of the system can use a variety of terminals, that is, the user can observe the video data collected and transmitted by the server in many ways, such as PC, mobile phone client of various popular Android systems, tablet computer, etc. In the future, multiple terminals can also be used at the same time to observe the video captured by the camera. In view of the good expansibility and openness of the Linux system, the system can be easily produced on a large scale. In this paper, the definition of mobile video surveillance system is introduced in detail, and its background and development process are summarized. According to the present situation, the development trend and research direction of mobile video surveillance system are put forward. The function of this design is that the video data collected by USB camera is stored to the server of Linux system, then the video data is compressed and encoded by M-JPEG on the server side, and then transmitted to the client through 3G network in real time. The client will display the received video data to the user, and the user can observe the video data collected by the camera in real time. Therefore, this design will be composed of four parts, namely, video data acquisition terminal, Linux system of ARM11 development board, transmission network, PC and Android mobile phone. The video compression and coding function which the video server is responsible for is M-JPEG coding to meet the requirements of real-time transmission of video data over 3G network. This paper puts forward the whole system design scheme, and then introduces how to realize the mobile video surveillance system in detail from two aspects: platform construction and driver transplantation, application software design of each part. The system is tested and the results are summarized. At the end of the article, the paper summarizes the whole paper, and puts forward the design and ideas for the development and development of this design.
