【摘要】 本课题是在研究和分析现有视频监控体系的基础上,针对当前工业环境监控系统整体设备成本高的缺点,提出了基于互联网的远程视频监控系统的设计方案。在旧有的监控系统中,一个监控摄像头需要连接三根视频信号线来进行数据传输,而且视频信号不能长距离传输,每隔若干个摄像头就需要一台工控机来控制,所以成本较高,不适合实现大面积的监控。本文提出的基于互联网的远程视频监控系统方案,是在利用现有网络的基础上,通过一台服务器连接多台摄像头,并只需接入互联网就可进行大范围的监控作业；现场摄像头采集到的监控数据可通过网络传输到远程监控端进行监控,同时在监控端可通过软件控制监控终端的动作进行监控,适用于工业环境的远程视频监控。本文首先简介了课题的研究背景以及项目的来源,阐述了视频监控系统的发展历史,对视频监控系统中应用的相关技术做了一定的说明。在仔细研究了嵌入式技术的基础上,对视频处理开发平台的功能需求和性能需求进行了分析,在总体设计原则下,提出了基于互联网的远程视频监控系统的总体设计方案,在此方案上对监控终端所需的主处理器和嵌入式操作系统进行了选择,其中微控制器选择的是基于ARM920T内核的S3C2440微控制器,嵌入式操作系统采用的是Linux系统。然后,围绕监控终端设计方案对视频终端的各个功能模块进行了设计,主要包括：视频模块；音频模块；网络模块；USB接口模块；外部存储器扩展模块；电源模块；继电器电路及J-TAG仿真接口等。最后,根据终端要求,完成了Linux操作系统的移植和外围设备的驱动,并使用USB摄像头对网络视频监控的实现进行了测试。更多还原

【Abstract】 This topic based on the research and the analysis of existing video surveillance system, because of the current industrial environment monitoring system overall equipment cost is too high, put forward the design based on the Internet video monitoring system solutions of remote. The old control system, a surveillance camera needs to connect three video signal lines for data transmission, because the video signal transmission line is not far enough, and every cameras need a industrial computer, so it is very expensive and not applicable achieving large area of monitoring. This paper based on the Internet video monitoring system of remote plan, using existing network in the basis, through a server connection many cameras, each camera just pick up a piece of string can well data transmission, can enlarge monitoring area; Field camera the monitoring data collected by the network transmission to remote monitoring, and the monitoring in monitoring software control can be through the monitor terminal monitor the actions, suitable for industrial environment video monitoring remote.This paper firstly introduces the topic research background and project source video monitoring system, then expounds the development history of video monitoring system, and application of the relevant technology made certain instructions.In studied the embedded technology, on the basis of video processing development platform, the function requirements and performance demands are analyzed.in principle, the overall design was proposed based on Internet video monitoring system of remote overall design scheme, in this scheme to monitor terminal on the main processor which is needed and embedded operating system of choice, the choice of micro controller is based on the ARM920T kernel S3C2440 micro controller, embedded operating system is Linux system.Secondly, around monitoring terminal design scheme to the video terminals modules to carry on the design, mainly including:video module; Audio module; Network module; USB interface module; External memory expansion module; Power supply module; Relay circuit and J-TAG simulation interfaceAt last, according to the terminal requirements, completed the Linux operating system transplantation and peripherals driver, and use network video monitoring USB webcam to fulfill a test.更多还原
