<p>PROBLEM TO BE SOLVED: To provide a control system that has high safety and rapidly releases a door lock when an obstacle is not enough thick to be sensed by a door end sensor in closing a door of a platform and thus a perfectly closing state of the door occurs. SOLUTION: The control system of a platform door comprises the platform door 3 disposed in the platform of a vehicle, the door end sensor 15 for detecting that the obstacle is grappled by the door, and an electromagnetic lock 17 for locking the door after the completion of closing of the door. When the obstacle lying out of a sensing range of the door end sensor is grappled by the door after the completion of closing of the door, the door end sensor is made to sense the obstacle by moving the obstacle, and a microcomputer controller 13 releases the door lock, re-opens the door from the grappled state of the obstacle by the door to a certain distance, and then closes the door again.</p> |
