Abstract

The invention discloses a device and a method for controlling a metro platform screen door. The device comprises a command interface unit, hardware logic, an output unit, software logic and a switching device, wherein the command interface unit is used for receiving external commands, the hardware logic is used for arbitrating external commands, the output unit is used for outputting external commands arbitrated by the hardware logic to a gating unit group, the software logic is used for monitoring working states of a hardware logic module and is used for arbitrating external commands and outputting external commands through a bus when the hardware logic breaks down, and the switching device is used for switching between the hardware logic and the software logic. When the hardware logic breaks down, the right of control is switched to the software logic, when a hardware logic control device of the metro platform screen door breaks down, an emergency door opening and closing method is provided, the normal operation of metros can be guaranteed, and the stability and the safety of metro operation can be improved.

Description

technical field [0001] The invention relates to the technical field of a subway platform screen door, in particular to a control device and method for controlling a subway platform screen door. Background technique [0002] The subway screen door (also called safety door) is a series of doors set along the edge of the subway platform, which consists of fixed doors, sliding doors, emergency doors and end doors. The sliding door corresponds to the train door and is used for passengers to get on and off the train. [0003] The door control unit (Door Control Unit, DCU) used to control the sliding door receives the door opening and closing signals, and controls the motor to drive the opening and closing of the sliding door according to the set door opening / closing parameters, so that passengers can get on or off the car conveniently The car protects the passengers on the platform. [0004] The door opening and closing signals received by the sliding door are external control c...
