摘要
结合计算机网络的IP组播技术和图像压缩技术,设计了适合无人值班的远程图像监控系统。给出基于组播技术的监控系统的组网结构,并阐述了系统软件各个功能的实现。该图像监控系统是以光纤为媒体、远距离传输数字信号的系统,所需的带宽远低于传输未压缩图像信号的带宽,非常适合于局域网中应用的系统。
To improve the automatically running level of the transformer substation, and to truly realize the unmanned duty, it is necessary to monitor the locale image of the important devices and sites. In this paper, the remote image supervising system is designed with the multicast technology of network and the image compression technology. And more, it is given that the network construction of system based on the multicast technology, and discussed that the software design of the systems functions. The digital image signal is transferred through fiber in this system. This system needs lower bandwidth than the system with uncompressing image signal, and is easily adapted to the local network.
