Study on the Framework of Urban Mass Transit Intelligent Comprehensive Monitoring System

The paper analyzes the development of information of urban mass transit system in recent years and sums up urban mass transit comprehensive monitoring system requirements. On this basis, puts forward comprehensive monitoring system features, which are full lines comprehensive monitor, all subsystems coordination in different conditions, information sharing and decision-making with high degree of autonomy, and so on. From the data flow and control flow point of view, three-layer system architecture was proposed, which are integrated decision-making layer,stationpsilas decision-making layer and on-site control layer. Then each layerpsilas structure and function are analyzed. Through the simulation of systems operation modes in different running conditions, coordination and information interactive among every subsystem are analyzed.
