Description

technical field

[0001] The invention relates to the technical field of rail transit teaching and training, in particular to a simulated sand table for an interface screen door of an urban rail transit platform. Background technique

[0002] The existing rail transit station screen door simulation device is used to simulate the safety circuit of the door machine of the screen door of the rail transit station, the door opening command and the door closing command issued by the screen door platform controller PEDC to the door body, and simulate the door status indicator light when the door is opened. The door status indicator light flashes after the door close command is issued, and the door status indicator light goes out after the simulated safety circuit is connected. The device can demonstrate the relationship between the door status indicator light, the door open and close command, and the safety circuit. The device is shielded from the urban rail transit platform. The com...
