Abstract

A method and an apparatus for deactivating defective doors or movable steps of a train.

Claims

1. In a train including a first door having a first controller, a second door having a second controller, and a remote, central activation device connected to the first and second train doors, the activation device configured to transmit an activation signal, a method for deactivating defective doors of the train comprising the method steps as follows:

determining that a fault has occurred at the second door; and

deactivating the second door by an activation signal transmitted from the remote, central activation device via the first controller of the first door.

2. The method as claimed in claim 1, wherein the fault occurs at the second door in an open position of the second door, and a closing process of the second door takes place via the first controller of the first door.

3. The method as claimed in claim 1, wherein the second door is signaled as unusable to the passengers by an optical device.

4. The method as claimed in claim 1, wherein the deactivating of the second door is monitored by video monitoring system.

5. A deactivation apparatus for deactivating a defective door of a train, the deactivating apparatus comprising:

a first train door having a first controller and a first locking device wherein the first train door is a non-defective train door;

a second train door having a second controller and a second locking device, wherein the second train door is a defective train door;

a central control center connected to the first and second train doors and configured to provide and transmit an activation instruction; and

wherein the defective train door is deactivated by the activation instruction via the first locking device of the non-defective door.

6. The deactivation apparatus as claimed in claim 5, wherein the second locking device is connected to the first controller of the non-defective train door.

7. The deactivation apparatus as claimed in claim 5, wherein the central control center is located remotely from the train doors.
