Research conclusions：(1)Based on the analysis about structure and function of urban rail ISCS，a muhi-Agent model for ISCS has been established．This paper obtain result about the composition structure of ISCS multi-Agent model．The internal components of BAS Agent and central Agent which are the most important parts in the model have been analyzed．The functions of each Agent in the model has been discussed．(2)The communication issue and CO-operation relation between the Agents in the model has been discussed well and guarantee the transmission synchronous between events information inside model．(3)This paper provides the theoretical evidence for the construction of urban rail integrated supervisory control system and the valuable reference to the study on the urban rail information.
