Development of a Detector of Foreign Objects Caught in the Doors with Improved Function for Preventing Passenger Dragging Accidents (2)

One type of accident that needs to be prevented to achieve train safety is passenger dragging accidents where trains start to move with the body or belongings of a passenger caught in the doors. The authors are developing a method of detection using door stop rubbers as a detection method with higher sensitivity than the traditional method of detecting foreign object caught in doors with a door close switch (limit switch). Detection of a foreign object in this method works by measuring as fluctuation of air pressure any change in the volume of the internal space of the door stop rubber being pressed and deformed by a foreign object. By using this method, a detection method has been established for dragging incidents immediately after the train starts moving - even thin objects that cannot be detected simply by their being caught in the door. Results were verified using a testing machine.
