  • 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: 8905196
    Abstract: An elevator group control apparatus performs operation control of a plurality of elevators by detecting a downward traffic flow ratio of traffic flows departing downward from floors higher than a prescribed main floor in the total traffic flow departing from one floor to another. If the downward traffic flow ratio is not less than a prescribed reference value, a standby mode for downward traffic flow is made effective, in which at least one elevator car is caused to be on standby on a floor higher than the main floor and at least one elevator car is caused to be on standby on the main floor.

  • Patent number: 8646581
    Abstract: An elevator group management system capable of appropriately performing car assignment processing without leaving any one behind and enabling a passenger to recognize a car to board without fail. A fellow passenger group assignment section assigns fellow passenger groups to respective passengers based on the contents of hall call registration for each floor received from a hall operation panel, and causes the hall operation panel that has sent the hall call registration to display names of the assigned fellow passenger. A fellow passenger group car assignment section executes, on the fellow passenger groups assigned by the fellow passenger group assignment section, car assignment processing of assigning any of a plurality of cars as an assigned car and, in a case of determining the assigned car, provides car control sections with a passenger guide command containing at least combination information on this assigned car that has been determined and the fellow passenger group.

  • Patent number: 8602172
    Abstract: A car-based running power computing mechanism computes running power values of each car in both cases including cases before and after a newly generated hall call is assigned. A car-based regenerative power computing mechanism computes regenerative power values of each car in the both cases. A car-based future running power computing mechanism computes future running power values of each car in the both cases. A car-based future regenerative power computing mechanism computes future regenerative power values of each car in the both cases. A car-based assigned total evaluation index computing mechanism obtains an in-travel power consumption value and an in-future-travel power consumption value based on the running power values, regenerative power values, future running power values, future regenerative power values and the like, to thereby compute assigned total evaluation indices of each car in the both cases.

  • Patent number: 8584810
    Abstract: In an elevator system, a destination call registration device converts operation key information corresponding to a pressed key into floor information by using building specification data. The destination call registration device generates a destination call registration request which includes the floor information converted from the operation key information and sends the destination call registration request to a group management control device. The group management control device registers the destination call for a destination floor indicated in the floor information. The group management control device sets building specification data and sends the building specification data to the respective destination call registration devices for conversion.

  • 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.

  • Patent number: 8505692
    Abstract: Provided is an elevator system which can perform an optimum assignment suited to the operation condition of elevators and can appropriately notify a user of accurate information. For this purpose, there are provided a call registration device which registers a destination call before boarding and a notification device which provides elevator information. Normally, immediately after registration of a destination call, the notification device provides information on an assigned car. On the other hand, when a prescribed assignment review condition is met, immediately after registration of a destination call, the notification device provides information to the effect that the registration has been accepted, thereafter the assignment of the elevator is reviewed, and the notification device provides information on an assigned car when the elevator responds to the destination call.
