摘要
文章介绍了一种在城市轨道交通综合指挥调度系统(TIDS)中进行全景化事故反演的实现方式。针对该系统对事故反演的要求,介绍了一种基于Bekeley DB的全景采样数据库,TIDS系统的各监控专业变化数据都可以存储在全景采样数据库中,该全景采样数据库支持基于时间戳的数据存储,高效的数据查询和数据断面获取,以及“回放态”的概念和切换过程,并据此设计完善的事故录制与事故反演实现方案。本方案能够保证用户在正常监控过程中随时切换至回放状态,查看以前任意时间断面的列车运行情况、设备工作状态以及调度员的所有操作、历史事件,方便操作员反演事故过程,有助于提高列车监控及其他专业监控的管理水平,加强综合指挥调度系统的完整性。
This paper introduces an implementation method of panoramic accident inversion in urban rail transit integrated command and dispatching system.According to the requirements of the system for accident inversion,a panoramic sampling database based on Bekeley DB is introduced.The change data of each monitoring discipline of TIDS system can be stored in the panoramic sampling database.The panoramic sampling database supports data storage based on timestamp,efficient data query and data section acquisition,as well as the concept of“playback state”and switching process,Based on this,a perfect scheme of accident recording and accident inversion is designed.This scheme can ensure that the user can switch to the playback state at any time during the normal monitoring process,view the train operation status,equipment working status and all operations and historical events of the dispatcher at any time section,facilitate the operator to inverse the accident process,help to improve the management level of train monitoring and other professional monitoring,and strengthen the integrity of the integrated command and dispatching system.
