城市轨道交通综合监控系统中事故反演功能的设计与实现

摘要

The accident inversion function plays an important role in comprehensive monitoring system. The previous urban rail comprehensive monitoring systems do not have inversion function or only record the accident inversion file from the present moment within a very limited period, therefore they lack flexibility and efficiency. This paper focuses on a method that could obtain accident inversion historical data from the real-time database, and provide the inversion analysis for any periods of time.%事故反演功能在城市轨道交通的综合监控系统中具有重要作用.以往的城市轨道交通综合监控系统往往不具备反演功能或者只能现场录制当前时刻开始的较短时间段的反演文件,因而缺乏灵活性和有效性.着重讨论了基于RT21-ISCS综合监控软件平台从实时历史数据库中获得事故反演数据源的方法,能够对城市轨道交通综合监控系统运行以来任意时段的场景进行反演分析.
