Description

Technical Field

[0001] The invention relates to station platform doors and station integrated management, in particular to a control system of equal potentials of the platform doors and station integrated management. Background Art

[0002] In the absence of a train stop, the platform door is connected to the station ground and disconnected from the rails to ensure the safety of passengers on the platform and prevent the platform door insulation failure point from discharging sharply and causing sparks. When the train enters the station and stops, the platform door body is controlled to disconnect from the station ground by receiving the platform door opening command, and the connection line with the rail is connected. The release current is monitored in real time to ensure that the passengers on the train are not harmed by the step voltage. When the passing current exceeds the limit value, the connection between the platform door and the rail is disconnected to avoid sparks at weak insulation points. The system monitors the conduction current of the equipotential connection line and can give a real-time alarm for poor insulation of the platform door. The platform door insulation monitoring uses a test source to apply a test voltage between the platform door and the busbar grounding wire, and tests the support insulation status of the top and bottom of all platform door structures. By performing logical judgment on the leakage current collected at each insulation point, the location of the insulation short circuit can be determined.
