【摘要】：現(xiàn)如今的科技社會中,隨著網(wǎng)絡科技的不斷進步,視頻監(jiān)控系統(tǒng)已經得到廣泛應用。社會對于安全的需求也隨著社會的變革不斷增加,人們對于視頻監(jiān)控系統(tǒng)的需求量也與日俱增,于是移動視頻監(jiān)控系統(tǒng)應運而生�；诋斚伦盍餍械腖inux系統(tǒng)和3G網(wǎng)絡,本論文將設計一款易于使用和推廣的移動視頻監(jiān)控系統(tǒng)。 本文通過對目前視頻監(jiān)控系統(tǒng)的市場需求以及發(fā)展趨勢的分析,結合理論實際可操作性,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,實現(xiàn)了移動視頻監(jiān)控系統(tǒng)的體積小,機動性強等特點,可以隨意安裝在各種小型房屋或其他空間內,因為3G網(wǎng)絡是移動通信網(wǎng)絡,所以甚至可以作為車載監(jiān)控系統(tǒng),隨時隨地向用戶顯示車內情況。該系統(tǒng)的用戶端可以采用多種終端,即用戶可以通過多種方式觀察服務器端采集到并傳輸過來的視頻數(shù)據(jù),例如PC機、當前流行的各種Android系統(tǒng)的手機客戶端、平板電腦等等,將來也可以實現(xiàn)多個終端同時使用,觀察攝像頭采集的視頻畫面。鑒于Linux系統(tǒng)良好的擴展性和開放性,該系統(tǒng)可以很方便的進行規(guī)�；a。 本文詳細介紹了移動視頻監(jiān)控系統(tǒng)的定義,概述了其背景以及發(fā)展過程,根據(jù)其現(xiàn)狀、監(jiān)控技術的理論知識提出了系統(tǒng)的未來發(fā)展趨勢和研究方向。本設計的功能實現(xiàn)過程為首先由USB攝像頭采集視頻數(shù)據(jù)存儲到Linux系統(tǒng)的服務器端,然后服務器端對視頻數(shù)據(jù)進行M-JPEG壓縮編碼,再通過3G網(wǎng)絡實時的傳輸給客戶端,客戶端會將接收到的視頻數(shù)據(jù)顯示給用戶,用戶可以實時的觀察到攝像頭端采集來的視頻數(shù)據(jù)。所以本設計將由四部分組成,即視頻數(shù)據(jù)采集終端(USB攝像頭)、視頻服務器端(ARM11開發(fā)板Linux系統(tǒng))、傳輸網(wǎng)絡(3G)、客戶機(PC和Android手機)。其中視頻服務器端所負責的視頻壓縮編碼功能采用的是M-JPEG編碼,以達到通過3G網(wǎng)絡實時傳輸對視頻數(shù)據(jù)的要求。 本文提出了完整的系統(tǒng)總體設計方案,然后從平臺搭建及驅動移植、各個部分的應用軟件設計兩個方面詳細介紹了移動視頻監(jiān)控系統(tǒng)如何實現(xiàn),并且對系統(tǒng)進行了測試和結果總結。在文章的最后對全文做出了總結,并對本設計的發(fā)展和后續(xù)開發(fā)提出了設計和想法。
[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.
