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 monitoring system based on wireless transmission is designed. The system development environment and software and hardware design are introduced in detail. The system uses ARM processor and embedded Linux as the core platform and transplants related drivers and web servers. It designs multithreaded video server and designs dynamic web pages using java applet technology on web server. The system will collect the video data sent over the wireless network to the Internet, customers browse the web to watch the video surveillance, video backup at the same time. The test results show that the system has strong mobility, supports multi-user access, and the monitoring picture is clear and smooth with good application prospect.
