Abstract: Platform Screen Door Monitoring System is an important part of Urban Transit station monitoring system. It integrates the function of platform screen door, integrated backup panel and etc. This article was based on the Windows operating system, developed a simulation interface of integrated backup panel by VC ++ programming. 3D model of platform screen door and train was constructed by using 3Ds Max, MultiGen Creator. The buttons and signal lights of integrated backup panel were used to control and display the states of the platform screen door, implement linkage between platform screen door and integrated backup panel.
