  • the control device 11 may notify the user that the maintenance staff is requested to be dispatched by, for example, a notification device provided in the car 7. After that, the operation of the control device 11 ends.
  • control server 15 may receive a request for dispatching a maintenance worker from the control device 11 before step S27.
  • step S27 the control server 15 determines whether the control device 11 of the elevator 2 in which the confinement has occurred requests the dispatch of a maintenance worker for rescue. If the dispatch of maintenance personnel is not requested, the operation of the control server 15 proceeds to step S26. On the other hand, when the dispatch of maintenance personnel is requested, the operation of the control server 15 proceeds to step S25.
  • step S25 the control server 15 arranges the dispatch of maintenance personnel for the rescue of the elevator 2 in which the confinement has occurred. After that, the operation of the control server 15 ends.
  • the feasibility determination unit 17 of the control system 1 determines whether or not the rescue operation is possible for the confinement of the first elevator regardless of whether or not there is a notification of confinement from the first elevator. The result is output to the control device 11.
  • the control system 1 outputs in advance whether or not rescue operation is possible to the control device 11 when confinement may occur due to an earthquake. Therefore, if the determination result of whether or not the rescue operation is possible is received, the control device 11 can promptly perform the rescue operation when the confinement occurs.
  • control system according to this disclosure can be applied to elevators where confinement may occur due to an earthquake.
