城市轨道交通智能综合监控系统体系结构

智能综合监控系统具有全线各系统综合监控、不同工况下各系统联动、信息高度共享和系统自主决策等特征。从数据流和控制流角度出发,提出系统的3层体系架构,即综合决策层、车站决策层和现场控制层。综合决策层负责监控全线范围内的系统,制订全线的综合决策,并与外部系统进行数据和信息交互。中央级综合监控中心具有控制、报警和画面显示等等功能。车站决策层负责监控本站范围内的各监控子系统,并协调各子系统的联动功能,提供车站级的决策。车站级综合监控中心具有实时信息采集、维护监控和报警处理等功能。现场控制层分为面向服务类、运营类和安全类等3类系统,包括6个子系统。系统的关键部分是信息共享平台和网络通信平台。构建信息共享平台的关键技术包括:数据源接口、信息融合、数据挖掘和信息发布等技术。网络通信平台的关键技术主要是目前通用的SDH,ATM等标准通信技术。

The Framework of Urban Mass Transit Intelligent Integration Supervision and Control System

Intelligent integration supervision and control system has the characteristics of integration supervision of every subsystem in the whole lines,the linkage of every subsystem under different working conditions,information share at high level,system self-determination and so on.On the basis of data stream and control flow,the system framework with three layers is put forward,that is integration determination layer,station determination layer and local control layer.Integration determination layer answers for the supervision of the system in the whole lines,establishing integration decisions of whole lines and data and information interchanging with exterior systems.Centrality integration supervision center has the functions of control,alarm,display and so on.Station determination layer answers for the supervision of every subsystem in the station scope,coordination the linkage functions of every subsystem and providing the decision at station layer.Station integration supervision system has the functions of real-time information collection,maintenance,supervision,alarm management and so on.Local control layer include six subsystems and can be divided into three classes,namely,service class,operation class and safety class.The central parts of the system are information share platform and network communication platform.The key techniques for constructing the information share platform include data interface technique,information fusion technique,data mining technique,information issuance technique and so on.The key techniques for constructing the network communication platform are the common standard communication techniques such as SDH,ATM and so on.
