摘要
在分析了现有系统的优缺点之后，提出了一种基于ＶｘＷｏｒｋｓ的视频监控系统的设计与实现方法。系统由远端和中心两部分组成。远端基于ＶｘＷｏｒｋｓ操作系统，在收到报警信号之后完成视频采集和压缩，接着通过通信接口将压缩数据传给中心。中心基于Ｗｉｎｄｏｗｓ操作系统，在接收到远端传来的压缩码流后解压缩，然后显示出来。同时，中心还能够以压缩或者原始的形式保存视频数据。目前，系统支持３种连接方式（网络、双绞线和无线）和２种图像格式（ＱＣＩＦ和ＣＩＦ）。
The design and implementation of the video surveillance system based on VxWorks is described after an analysis of the advantages and disadvantages of the existing systems. The system consists of two parts the remote end and the center. The remote end based on VxWorks performs video capture and coding after receiving the warning signal. Then it sends the compressed data to the center by the communication interface. The center,based on Windows decodes the compressed stream after receiving it and displays it. Meanwhile the center can save the video data using the compressed of original format. Now the system supports 3 types of connection (network twisted pair and wireless)and 2 kinds of image formats (QCIF and CIF).
