Research on Urban Rail Transit Network Command Center Information Platform

Drawing lessons from the constructions of domestic and foreign urban rail transit network operation coordination platform, the paper puts forward the structure of network command center information platform with the full life cycle management idea and the open architecture. Besides, it designs the main platform functions and explores key technologies such as the information fusion mechanism, real-time monitoring with GIS technology, equipment alarm monitoring and intelligent emergency decision. The network command center integrated information platform which has important functions in the operation coordination, resource sharing, and emergency decision is the main technical support system of urban rail transit network operation and management. It can grasp the real-time operation situation of each rail transit line, use for the daily operation supervision, and especially unify coordination control during emergencies to implement emergency linkage by organizing relevant departments and assembling the rescue resources. The running effect of the network command center information platform suggests that the system can effectively improve the urban rail major accident or emergency rapid response capability and scientific decision so as to ensure the safety of urban transportation.
