Abstract

The invention discloses a platform gate and train anti-pinching system and method. The system comprises a platform gate PSD anti-pinching safety host, a three-dimensional laser radar and an alerter. The three-dimensional laser radar is used for performing obstacle three-dimensional scanning detection on the area between the platform gate and the train in real time at one end of the platform by using the emitted laser scanning surface when both of the platform gate and the train gate are in the closed state and transmitting the obstacle detection information to the PSD anti-pinching safety host. The obstacle detection information includes the three-dimensional contour information of the obstacle. The PSD anti-pinching safety host is used for processing the obstacle detection information andtransmitting the processing result to the alerter. The alerter is used for performing alarming according to the processing result. According to the platform gate and train anti-pinching system and method, three-dimensional scanning detection can be performed on the blind area between the platform gate and the train so that the detection accuracy and the train operation safety can be enhanced.

Description

technical field

[0001] The invention relates to the technical field of emergency safety, in particular to an anti-pinch system for platform doors and trains. Background technique

[0002] At present, each station on most of the subway lines is equipped with a platform door, which can form a safety isolation between vehicles and passengers, and ensure the safety of passengers to a certain extent. When the vehicle stops in the station, the platform door will be opened; when the platform door needs to be closed and there is no foreign object detected in the middle of the platform door, the platform door will be closed.

[0003] When the platform doors are closed, foreign objects will be detected in the gap between the two platform doors. When there is a foreign object in the gap, the platform doors will remain open.

[0004] But there is a blind spot between the platform door and the train, that is, between the platform door and the train door, between the car body and the gla...
