The invention discloses a method for detecting foreign matters in a gap between a platform screen door and a train door and a monitoring system.The platform area is provided with an ultrasonic detection system, the detection range of the ultrasonic detection system at least covers the gap between the platform screen door and the train door stopped at the platform, and the method is used for the ultrasonic detection system. The method for detecting the gap foreign matter between the platform screen door and the train door comprises the steps of obtaining an ultrasonic detection signal of the gap between the platform screen door and the train door; determining that foreign matters exist in gaps between the platform screen doors and the train doors according to the ultrasonic detection signals; and sending the information that the foreign matters exist to a platform door control system to trigger interlocking protection. According to the method for detecting the foreign matter in the gap between the platform screen door and the vehicle door, ultrasonic waves are used for detecting the foreign matter, the ultrasonic wave diffraction phenomenon is small, foreign matter detection is more accurate, and compared with a light curtain generator, the detection range is more comprehensive, and interference is not likely to happen.
本发明公开了一种检测站台屏蔽门与车门之间间隙异物的方法和监控系统,其中,站台区域设置有超声波检测系统,超声波检测系统的检测范围至少覆盖站台屏蔽门与停在站台的列车车门之间的间隙,方法用于超声波检测系统,检测站台屏蔽门与车门之间间隙异物的方法包括:获取对于站台屏蔽门与列车车门之间间隙的超声检测信号;根据超声检测信号确定站台屏蔽门与列车车门之间间隙存在异物;发送存在异物的信息给站台站门控制系统,以触发联锁保护。本发明的检测站台屏蔽门与车门之间间隙异物的方法,利用超声波进行异物的探测,超声波绕射现象小,异物检测更加精准,以及相较于采用光幕发生器,检测范围更加全面且不易受到干扰。
