  • Patent number: 9079752
    Abstract: According to the present invention, when a parking floor is set as a remote-hall-operating-panel-installed floor, the parking floor can be canceled. As a result of this, during the movement of a passenger from a remote hall operating panel to an elevator hall, it is possible to prevent a car from being on standby at a remote-hall-operating-panel-installed floor. Therefore, because a car to which a remote hall registration has been assigned can effectively use the moving time of the passenger and hence it is possible to improve the operation efficiency of the whole group supervisory control system. Furthermore, it is possible to reduce useless runs and hence to reduce power consumption.

  • Patent number: 8567569
    Abstract: An elevator group management system improving operational efficiency in consideration of a situation change that has occurred after a destination floor registration in a hall. An assigned car review mechanism executes assigned car review processing in units of review registration information sets each including at least one piece of provisionally assigned car registration information managed by a registered destination floor hall call management section during a review period. After ending the assigned car review processing, the assigned car review mechanism modifies the contents of the provisionally assigned car registration information in the registered destination floor hall call management section based on the contents of the review registration information set after modification. That is, the assigned car review mechanism newly registers the provisionally assigned car registration information after review and erases the provisionally assigned car registration information before review at the same time.
