【摘要】：伴随着计算机和嵌入式技术的快速发展，视频监控系统也随之经历了从模拟监控到现在的嵌入式无线视频监控，并且被广泛的应用在各个领域中，成为研究的一个重要热点。本文在以中国电子科技集团第四十九研究所的物资仓库视频监控项目的背景下，具体研究了如何搭建一个嵌入式无线视频监控系统，重点解决了系统中视频信号实时采集和传输方法、视频图像显示和存储等问题，实现了一种成本低，性能稳定，便于移动使用的视频监控系统。这对于嵌入式无线视频监控系统的发展有重要的实际意义。在讨论了当前嵌入式无线视频监控系统涉及的相关技术以及系统开发流程的基础上，针对研究所实际项目的软硬件需求，确定了本课题的总体设计方案，自主搭建了一套完整的视频监控系统。此无线视频监控系统分为视频监控设备、网络传输和客户端监控三个部分。视频监控设备硬件资源主要由Mini2440开发板，USB摄像头，WiFi无线网卡组成，，软件方面主要是Linux系统设计，包括Bootloader移植，内核移植，根文件系统，及视频服务器应用程序。客户端则通过上位机浏览器或者监控管理系统软件实现视频监控。设计分析了监控设备上的视频服务器应用程序，主要包括视频采集程序和视频传输程序两部分，同时采用HTML标记语言制作了相应网页，以便客户端使用浏览器方式监测视频。为了方便用户进行视频管理，使用VC6.0自主设计开发了视频监控软件。该软件可实现以下功能：通过上位机来控制视频采集程序的开关，显示采集的图像，录像保存等，同时为了证明本软件具有良好的功能扩展性，在原有基础上增加了一扩展应用实例。最后，通过实际测试此视频监控系统，证明它能够实现预期功能，达到项目要求，是个合理可用的视频监控系统。
[Abstract]:With the rapid development of computer and embedded technology, video surveillance system has experienced from analog monitoring to embedded wireless video monitoring, and has been widely used in various fields, become an important research hotspot.Under the background of the material warehouse video surveillance project of the 49 Institute of China Electronic Science and Technology Group, this paper studies how to build an embedded wireless video surveillance system.The problems of real-time video signal acquisition and transmission, video image display and storage in the system are solved, and a low cost, stable performance and convenient mobile video monitoring system is realized.This has important practical significance for the development of embedded wireless video surveillance system.On the basis of discussing the related technology and system development flow of embedded wireless video surveillance system, according to the software and hardware requirements of the actual project of the institute, the overall design scheme of this subject is determined.A complete video surveillance system is built independently.The wireless video surveillance system is divided into three parts: video monitoring equipment, network transmission and client monitoring.The hardware resource of video surveillance equipment is mainly composed of Mini2440 development board, USB camera and WiFi wireless network card. The software is mainly Linux system design, including Bootloader porting, kernel porting, root file system, and video server application program.The client realizes video monitoring through the PC browser or the monitoring management system software.The application program of video server on the monitoring equipment is designed and analyzed, which mainly includes two parts: video capture program and video transmission program. At the same time, the corresponding web pages are made by using HTML markup language, so that the client can monitor the video in the way of browser.In order to facilitate the user to manage the video, the video monitoring software is designed and developed by using VC6.0.The software can realize the following functions: the switch of video acquisition program is controlled by the upper computer, the captured image is displayed, the video is saved, and so on. Meanwhile, in order to prove that the software has good function expansibility,An extended application example is added on the original basis.Finally, by testing the video surveillance system, it is proved that it can achieve the expected function and meet the requirements of the project. It is a reasonable and usable video surveillance system.
