摘要

研究目的：目前许多城市既有轨道交通视频监控系统采用的是标清模拟或标清数字视频方案。随着视频监控技术的迅速发展，当既有轨道交通线路延伸及扩展时，如何发展延伸线视频监控技术，满足地铁日益增长的监控需求，既不影响既有线路的运营，又与既有线系统相互兼容，是目前许多轨道交通延伸线工程越来越需要考虑的问题。

研究结论：本文对某地铁延伸线工程视频监控系统分别研究了标清数字视频和全高清视频两种设计方案，通过对这两种设计方案的比较和分析可知：（1）地铁视频监控系统在延伸线工程中完全可以升级建设为全高清视频技术方案；（2）方案除新建车站子系统和控制中心子系统外，既有线路的系统设备需要进行控制协议的开放以及接口扩容的改造等工作；（3）此方案解决了目前地铁延伸线工程视频监控系统采用全高清技术方案时与既有线路标清视频监控系统的兼容和中心统一调看等技术难题。

Abstract： Abstract：Research purposes： At present, many cities use either standard definition analogy solution or standard definition digital solution for the video monitoring system in existing rail transit lines, but the video monitoring technology is upgrading and developing quickly. When the rail transit lines need to extend, how to develop the technology of the video monitoring system and meet the growing demand of metro, neither affect the existing line operation nor interfere the existing system need to be considered in a lot of extension line projects.
Research conclusions：The research of standard definition digital solution and full high-definition solution in video monitoring system is discussed in a metro extension line in this paper.（1）According to analysis and comparison of the two solutions, the video monitoring system in extension line project can upgrade to full high-definition video solution.（2）In addition to build station subsystem and control centre subsystem, the open of control protocol and the reformation of interface should be done in system equipments of existing line.（3）The design can solve the problem of monitoring in operation control center and compatibility while the existing line use standard definition digital solution and the extension line use full high-definition video monitoring.
