  • Patent number: 8439169
    Abstract: An elevator group supervision controlling apparatus has a response time predicting means, a passenger movement estimating means, a standby time predicting means, a candidate car selecting means, an allocating means, and an instructing means. The response time predicting means predicts response time to a car call from a remote call registering apparatus for respective cars. The passenger movement estimating means estimates passenger moving time based on a positional relationship between the remote call registering apparatus and a landing. The standby time predicting means predicts the standby times of each of the cars based on the response time and the passenger moving time. The candidate car selecting means includes cars for which standby time is shorter than a predetermined time interval in candidate cars, and excludes cars for which standby time is greater than or equal to the predetermined time interval from the candidate cars.

  • Patent number: 8286755
    Abstract: In an elevator system floors each include: a hall registration device that places a plurality of car calls for moving a car to destination floors different from one another; and a display device that displays the car that has been assigned the plurality of car calls. A limit value setting mechanism sets, for each of the plurality of floors separately, a limit value for limiting a count of the plurality of car calls that can be assigned to the same car. A count-up mechanism obtains, when a new car call is made, a call count of each car by a given method, based on information about the plurality of car calls that have been assigned to the car. A candidate car selector compares the limit value set to a floor where the new car call is made and the call count of the each car, to thereby select, as a candidate car, the car to which the new car call can be assigned from among the cars.

  • Patent number: 8006807
    Abstract: An elevator group control apparatus includes a parameter calculating unit for determining a weighting factor for an item to be evaluated, which is calculated from a running distance estimated by an estimation arithmetic operation unit by taking into consideration a relation between a running distance of an elevator and a passenger average waiting time, and an evaluation arithmetic operation unit for calculating a total evaluated value from an item to be evaluated of a passenger waiting time, an item to be evaluated of the running distance, and the weighting factor determined by the parameter calculating unit. The elevator group control apparatus selects an elevator whose total evaluated value is the best from among the plurality of elevators, and assigns a hall call to the selected elevator.

  • Patent number: 7963372
    Abstract: An elevator evacuation support apparatus evacuates building occupants that have been left inside a building to a refuge floor in an emergency by managing operation of an elevator in which a plurality of floors function as service floors. The elevator evacuation support apparatus has an evacuating operation implementing portion, an evacuating operation time calculating portion, and an evacuating operation determining portion. The evacuating operation implementing portion designates at least one of the service floors as a rescue floor, and implements an evacuating operation for the elevator for transporting the building occupants from the rescue floor to the refuge floor. The evacuating operation time calculating portion receives urgency level information that indicates a degree of urgency, and calculates an estimated amount of time for continuing the evacuating operation as an evacuating operation time based on the urgency level information.
