Anti-pinch detection system and method used between metro shield door and train

Abstract

The embodiment of the invention provides an anti-pinch detection system and method used between a metro shield door and a train. The system involves a sensor, a control host and a human-computer interaction device; the sensor comprises a three-dimensional laser radar and a camera, wherein the three-dimensional laser radar is used for detecting whether an object exists between the shield door and the train or not, and if yes, a real-time image is acquired by the camera; and the control host is used for acquiring detection data from the sensor in real time and displaying the detection data through the human-computer interaction device, and the detection data comprise a detection result from the three-dimensional laser radar and the real-time image acquired by the camera. According to the embodiment of the system, the sensor integrated with the three-dimensional laser radar and the camera is used for detecting whether the obstacle exists in front of the train or not, and the condition infront of the train can be rapidly judged by combining the acquired real-time image, so that casualties or equipment accidents can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to an anti-pinch detection system and method used between a subway screen door and a train. Background technique [0002] With the development of automatic detection devices and the improvement of preparation capabilities, more and more multifunctional automatic detection devices have been applied to industrial production and the safety of civil facilities. Among them, the position-sensitive detector is widely used in the anti-pinch detection system between the subway screen door and the train. At present, the conventional PSD anti-pinch detection method is to install a position-sensitive sensor on the top or side of the train door to detect whether there are people or objects within a certain range in front of the train door. When a person or object is detected, further opening and closing of the train door is prevented, or an audible and visual alarm signal is issued. [0...
