Problems solved by technology

If manual observation is used, the detection accuracy rate is not high; especially when there are curved stations, there is a blind area for observation; if the track side laser shooting method is used, on the track side, the train running will cause the platform plate to vibrate, which will easily cause the laser shooting to deviate. Effective detection, false positives
In addition, when the laser beam is used, the laser scanning device is installed under the air channel beam of the platform door system, which is located on the side of the track and at a high position, which is not convenient for maintenance

Abstract

The invention provides a foreign matter detection device and a platform door system and belongs to the technical field of rail transit. The foreign matter detection device is mounted on a top box assembly of the platform door system through a connecting support. The foreign matter detection device comprises an L-shaped mounting support, wherein two sides of the mounting support are connected with a controller and a scanning head respectively, the connecting support and the controller are located on the same side of the mounting support, and the scanning head is driven by the controller to scan a gap between a train and a platform door in the platform door system. According to the foreign matter detection device and the platform door system, the connecting support is installed on the top box assembly, so the foreign matter detection device does not vibrate in the opening and closing process of a shielding door on a train, and then reliability of a scanning head when the scanning head scans a gap between the train and the platform door is improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a detection device, in particular to a foreign object detection device and a platform door system. Background technique [0002] There is a certain gap between the platform door and the train, which sometimes occurs after the platform door and the train door are closed, and there are foreign objects in the gap, which will cause safety hazards in the actual operation process. [0003] The existing safety detection methods between the subway train and the platform door mainly include manual observation and laser beam shooting. If manual observation is used, the detection accuracy rate is not high; especially when there are curved stations, there is a blind area for observation; if the track side laser shooting method is used, on the track side, the train running will cause the vibration of the platform plate, which will easily cause the laser shooting to deviate. Effective dete...
