摘要
综述了我国远程图像监控系统的现状和发展趋势 ,分析和讨论了涉及的技术和标准 ,重点介绍了远程图像系统的设计思路。其中窄带系统介绍了基于PSTN和GSM网络的设计 ,宽带系统则结合网络多媒体技术论述了图像监控系统近年来的新发展。针对图像监控系统在电力系统中应用的历史和现状 ,结合未来的发展 ,给出了地、市级图像平台和变电站远程图像监控系统的设计方案。
This paper summarizes remote video surveillance system's present situation and direction of development. Technology and standard involved in the system are analyzed and discussed, especially recommend a new design idea. In narrow system,a design scheme based on PSTN and GSM network is proposed; in broadband system,recent development of video surveillance system is discussed,by combining network multimedia technology. Based the history and present situation of the application in electric power system,combined with the development in the near future,a design scheme of district video platform and substation's remote video surveillance system is proposed.
