  • Patent number: 8405937
    Abstract: A method and a system control platform doors that are disposed at a distance to each other corresponding to a train to be entered via the platform.

Each group may be connected to at least two controllers via one respective transfer medium, that control signals of at least one controller are transferred to the platform doors via the transfer media, such that in case of failure of one controller, the functions of the failed controller are transferred to the at least second controller.
