【摘要】：隨著社會(huì)的不斷發(fā)展與進(jìn)步,人們的安防意識(shí)逐漸增強(qiáng),視頻監(jiān)控系統(tǒng)以其準(zhǔn)確、直觀和高效的特點(diǎn),在安防領(lǐng)域得到了廣泛的應(yīng)用。傳統(tǒng)的視頻監(jiān)控系統(tǒng)大多是以有線網(wǎng)絡(luò)為主,其安裝布線工程量大、移動(dòng)性差且成本高。隨著WiFi、4G等無線傳輸技術(shù)及嵌入式技術(shù)的發(fā)展,視頻監(jiān)控系統(tǒng)正朝著無線化、小型化和低成本等方向發(fā)展。本文通過研究無線視頻監(jiān)控的關(guān)鍵技術(shù),設(shè)計(jì)出了一個(gè)基于嵌入式的無線視頻監(jiān)控系統(tǒng)。該系統(tǒng)包括三部分,分別為監(jiān)控前端、中心服務(wù)器和移動(dòng)監(jiān)控終端。中心服務(wù)器創(chuàng)建WiFi熱點(diǎn),監(jiān)控前端和移動(dòng)監(jiān)控終端分別接入WiFi熱點(diǎn)與中心服務(wù)器無線連接,從而克服了有線監(jiān)控技術(shù)的缺陷。本文完成的主要研究工作如下:(1)根據(jù)本文設(shè)計(jì)的內(nèi)容和需求,提出了基于嵌入式的無線視頻監(jiān)控系統(tǒng)總體設(shè)計(jì)方案,并分別提出了監(jiān)控前端、中心服務(wù)器、移動(dòng)監(jiān)控終端的設(shè)計(jì)方案。(2)搭建了嵌入式服務(wù)器的硬件平臺(tái)及軟件開發(fā)環(huán)境,包括嵌入式Linux操作系統(tǒng)的U-Boot移植、內(nèi)核移植及構(gòu)建根文件系統(tǒng)。(3)嵌入式服務(wù)器應(yīng)用軟件的開發(fā),完成了多路監(jiān)控視頻的采集、壓縮編碼及無線傳輸。(4)中心服務(wù)器端應(yīng)用軟件的開發(fā),使用Qt開發(fā)與用戶交互的友好界面,完成了多路監(jiān)控視頻數(shù)據(jù)的接收與轉(zhuǎn)發(fā)、視頻解碼、視頻存儲(chǔ)、視頻播放及視頻的動(dòng)態(tài)檢測(cè),并對(duì)動(dòng)態(tài)視頻進(jìn)行備份存儲(chǔ)。(5)移動(dòng)監(jiān)控終端應(yīng)用軟件的開發(fā),在Android系統(tǒng)上實(shí)現(xiàn)了對(duì)多路監(jiān)控視頻數(shù)據(jù)的接收及解碼播放等功能。實(shí)驗(yàn)測(cè)試結(jié)果表明,本文設(shè)計(jì)的基于嵌入式的無線視頻監(jiān)控系統(tǒng)達(dá)到了系統(tǒng)設(shè)計(jì)要求,監(jiān)控視頻圖像清晰流暢,并具有準(zhǔn)確性高和實(shí)時(shí)性好的優(yōu)點(diǎn)。
[Abstract]:With the continuous development and progress of society, people's security awareness is gradually enhanced, video surveillance system with its accurate, intuitive and efficient characteristics. In the field of security has been widely used. The traditional video surveillance system is mostly wired network, its installation and wiring project is large, mobility is poor and high cost. With WiFi. With the development of wireless transmission technology such as 4G and embedded technology, video surveillance system is developing towards wireless, miniaturization and low cost. A wireless video surveillance system based on embedded system is designed. The system consists of three parts: the front end, the central server and the mobile monitoring terminal. The center server creates the WiFi hotspot. The monitoring front end and the mobile monitoring terminal are connected to the WiFi hot spot and the central server wireless connection respectively. In order to overcome the shortcomings of cable monitoring technology. The main research work completed in this paper is as follows: 1) according to the content and requirements of this paper, the overall design scheme of wireless video surveillance system based on embedded is put forward. And put forward the monitoring front-end, central server, mobile monitoring terminal design scheme. 2) built the embedded server hardware platform and software development environment. Including the U-Boot transplantation of embedded Linux operating system, kernel transplantation and the development of embedded server application software to build root file system. Compression coding and wireless transmission. 4) the development of the application software of the central server, using QT to develop friendly interface with the user, completed the receiving and forwarding of multi-channel surveillance video data, video decoding. Video storage, video playback and video dynamic detection, and dynamic video backup storage. 5) Development of mobile monitoring terminal application software. The functions of receiving and decoding video data are realized on Android system. The experimental results show that. The wireless video surveillance system based on embedded system meets the requirements of system design. The video image is clear and smooth, and has the advantages of high accuracy and good real-time.
