摘要
介绍了一种新型网络化数字视频实时监控系统。该系统以基于嵌入式处理器和嵌入式实时操作系统VxWorks的MPEG 4网络硬盘录像机为前端测控装置,通过TCP/IP通信端口接入二级宽带局域网,将摄像机采集的模拟视频信号处理转换为MPEG 4格式的IP数据流后直接发送给网上的PC机,PC机可以利用应用软件或IE浏览器实时预览视频图像。叙述了监控系统的硬件结构、软件功能结构,并给出了该系统在军事仓库群的网络视频监控中的实用效果和可推广的场合。
The system is based on specially designed MPEG4 embedded net DVRs and run under RISC and embedded operating system VxWorks as its remote controllers. The net DVRs are connected to LAN via TCP/IP communication port. After analog video signal captured by cameras is transformed to MPEG4 IP data stream by the net DVRs, the stream is sent to PC machines in the network. The machines can preview video signal through application software or IE browser in real time. Hardware structure and software functions of the video system are given and realization effect and applicable environment of the system are described in detail.
