Anti-pinch system and method for platform screen door and train

An anti-pinch method for a platform screen door and a train, comprising:

• when both the platform screen door and a train door are in a closed state, a three-dimensional laser radar performing 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 sending detection information of the obstacle to a PSD anti-pinch safety host;
• the PSD anti-pinch safety host receiving the detection information of the obstacle sent by the three-dimensional laser radar, processing the detection information of the obstacle and sending a processing result to an alarm;
• and
• the alarm receiving the processing result, and giving an alarm according to the processing result,
• wherein the detection information of the obstacle comprises three-dimensional contour information of the obstacle,
• wherein after both the platform screen door and the train door are closed and before the three-dimensional laser radar performs the detection on the obstacle in the area between the platform screen door and the train, the method comprises:
• determining an installation position of the three-dimensional laser radar to be installed at the end of the platform, according to a pulse intensity of a laser emitted by the three-dimensional laser radar, a length of the train, an angular resolution of the three-dimensional laser radar and a distance between the platform screen door and an outer wall of the train close to the platform screen door.
