Abstract

A method for deactivating a defective door of a train. The method steps include: providing a first door and a first controller; providing a second door and a second controller; providing a separate remote, central activation device configured to transmit an activation signal; 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. A deactivation apparatus for deactivating a defective door of a train, the deactivating apparatus including: a first train door, a first controller, and a first locking device; a second train door, a second controller, and a second locking device, wherein the second train door is a defective train door; a separate, central control center connected to the first and second train doors and configured to provide and transmit an activation instruction, wherein the defective train door is deactivated by the activation instruction via the first locking device of the non-defective door.

Claims

1. A method for deactivating a defective door of a train, the method steps comprising:

providing a first door and a first controller associated with the first door;

providing a second door and a second controller associated with the second door;

providing a separate remote, central activation device configured to transmit an activation signal;

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.

2. The method as claimed in claim 1, wherein when the fault occurs at the second door in an open position of the second door, 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 passengers by an optical device.

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

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

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

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

a separate, 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.
