嵌入式无线视频监控系统的设计与实现

Design and Implement of Embedded Wireless Video Surveillance System

设计了一种基于无线传输的嵌入式视频监控系统,详细介绍了系统开发环境的搭建及软硬件设计。系统以ARM处理器和嵌入式Linux为核心平台,移植了相关驱动和web服务器;设计了多线程视频服务器,并在web服务器端使用java applet技术设计了动态网页。系统将采集到的视频数据通过无线网络发送到Internet,客户以浏览网页的方式观看监控视频,同时将视频备份下来。测试结果表明,该系统移动性强、支持多用户访问、监控画面清晰流畅,有很好的应用前景。

An embedded video surveillance system based on wireless transmission was designed. The development environment and design of the hardware and software was presented. The system used ARM and embedded Linux as core platform, porting some drive program and embedded web server; designing a multi-threaded video server and dynamic web pages using java applet technology. Video data is translated to Internet by wireless network and clients can view the remote monitoring video through browser with the video saved at the same time. The test results show that the system has high reliability, supports more gestures, and the monitor screen is clear and smooth, with good prospects in using.
