Research conclusions：The purposes of establishment of the Integrated Supervision and Control System(ISCS) for the urban rail transit are to realize the resource sharing among the systems, guarantee that the correlation for business and the coordination for event can be conducted automatically among the relevant systems and deal with the events that happen suddenly. The deep integration mode under condition of sorting and scale can be used to the Integrated Supervision and Control System(ISCS) under establishment for the urban rail transit. With this mode, the subsystems that are easily integrated and the hardware parts that are consistent should be integrated. The big subsystems with high cost and high risk in integration should be interconnected.
