Abstract
An anti-pinch system and a method for a platform screen door and a train are disclosed. The system includes: a platform screen door (PSD) anti-pinch safety host, a three-dimensional laser radar and an alarm, wherein when both the platform screen door and a train door are in a closed state, the three-dimensional laser radar performs a three-dimensional scanning detection on an obstacle in an area between the platform screen door and the train in real time at an end of a platform by using an emitted laser scanning surface, and sends detection information of the obstacle to the PSD anti-pinch safety host; the detection information includes three-dimensional contour information of the obstacle; the PSD anti-pinch safety host is configured to process the detection information and send a processing result to the alarm; and the alarm is configured to send out an alarm according to the processing result.
