Description

  The present invention relates to a crew member detection interlock control device for a railway platform door, and more particularly to an interlock release system for the platform door.

  The railroad platform door is interlocked so that the door does not open when the railroad vehicle is not present.

  The opening / closing of the home door may be performed by the driver from within the vehicle or by the conductor getting off the platform.

  Detection of the presence of a railway vehicle is generally performed by a track short circuit (the track is a circuit, and when a rail vehicle is present, this circuit is shorted by a wheel).

  Also, a boarding door operation system (see Patent Document 1 below) using a remote controller carried by station staff, and a platform safety means overcoming detection device for detecting overcoming of safety means installed on the platform. (See Patent Document 2 below).
