Cableway with a vehicle having a closure drive and failsafe locking monitoring

A cableway having a station, at least one vehicle, and a cableway controller for controlling the cableway, wherein a closure device and a closure drive for closing the closure device are provided on the vehicle, and a locking unit for locking the closure device is provided on the vehicle, wherein a locking monitor for detecting the locking status of the locking unit is provided on the vehicle, and the vehicle transmits the locking status to the cableway controller, and wherein the cableway controller prevents the vehicle from traveling out of the station in the event of defective locking, the cableway comprising:

• a current collector on the vehicle
• a first busbar in the station the current collector being configured to contact the first busbar when the vehicle travels through the station in a direction of movement at least after the closing and locking of the closure device;
• a first station powerline modem connecting the first busbar with the cableway controller
• a vehicle powerline modem on the vehicle connected with the current collector,
• a locking evaluation unit on the vehicle and, following the closing and locking of the closure device, configured to query the locking status from the locking monitor and transmit the locking status to the cableway controller by the vehicle powerline modem via the first busbar and the first station powerline modem by powerline communication;
• a second busbar arranged in the station after the first busbar in the direction of movement,
• a second station powerline modem connected to the cableway controller, wherein the second busbar is connected with one of the first station powerline modem or the second station powerline modem;
• wherein the cableway controller stops the cableway in the event of defective locking, resulting in the vehicle coming to a standstill near the first busbar (10)
• wherein the locking evaluation unit queries the locking status at least once from the locking monitor and again transmits the locking status with the vehicle powerline modem via the first busbar or the second busbar and the first or second station powerline modem to the cableway controller while the vehicle is near the first or second busbar;
• and
• wherein the cableway controller starts the cableway when a correct locking of the locking unit has been signaled by the re-transmitted locking status.
