Abstract

Elevators (104) in a group elevator system (100) are controlled to facilitate transport of a large item (LI). A destination entry input device receives an input from a passenger (102) indicating that the passenger (102) has a large item (LI) to be transported in the group elevator system (100). The passenger (102) with the large item (LI) is assigned to an elevator (104) having capacity to accommodate the passenger (102) and the large item (LI).

Claims

1. A method for controlling elevators in a group elevator system, the method comprising:

receiving an input from a passenger on a destination entry input device indicating that the passenger has a large item to be transported in the group elevator system; and

assigning the passenger with the large item to an elevator with capacity to accommodate the passenger and the large item.

2. The method of claim 1, wherein the assigning step comprises:

determining a number of passengers assigned to each elevator in the group elevator system; and

assigning the passenger with the large item to a nearest elevator with less than a threshold number of assigned passengers.

3. The method of claim 1, and further comprising:

limiting a number of passengers that are assigned to the elevator assigned to the passenger with the large item until the passenger with the large item reaches a destination floor.

4. The method of claim 1, wherein the receiving step comprises:

receiving a signal when a large item key on the destination entry input device is pressed by the passenger.

5. The method of claim 1, wherein the receiving step comprises:

receiving a validation code input on the destination entry input device from the passenger.

6. The method of claim 1, wherein after the receiving step, the method further comprises:

receiving a destination floor input from the passenger on the destination entry device.

7. A system comprising:

a group of elevators operable to transport each of a plurality of passengers to one of a plurality of floors;

a destination entry input device on at least one floor that provides an interface for each passenger to input a destination floor, wherein the destination entry input device includes a large item key for use by a passenger having a large item to be transported in one of the elevators; and

a dispatch controller for assigning an elevator to each passenger based on the destination input information and for assigning a passenger with a large item who presses the large item key to a nearest elevator having capacity to accommodate the passenger and the large item.

8. The system of claim 7, wherein the dispatch controller determines a number of passengers assigned to each elevator in the group elevator system and assigns the passenger with the large item to an elevator with no other passengers assigned to the elevator.

9. The system of claim 7, and further comprising:

a validation device that facilitates a validation action by the passenger subsequent to pressing the large item key to prevent misuse of the large item key.

10. The system of claim 9, wherein the validation device comprises a keypad on the destination entry input device to facilitate entering a validation code.

11. The system of claim 9, wherein the validation device comprises a key reader to facilitate use of a validation key by the passenger.

12. The system of claim 7, wherein the destination entry input device includes a communication device selected from the group consisting of a display and an acoustic transducer.

13. A method for facilitating transport of a large item in a group elevator system, the method comprising:

receiving a first input indicating an origin floor of the large item in the group elevator system;

receiving a second input indicating a destination floor of the large item in the group elevator system;

determining status information for each elevator in the group elevator system; and

assigning the large item to an elevator having capacity to accommodate the passenger and the large item.

14. The method of claim 13, and further comprising:

dispatching the assigned elevator to the origin floor.

15. The method of claim 13, and further comprising:

limiting loads subsequently assigned to the elevator that is assigned to the large item until the large item reaches the destination floor.

16. The method of claim 13, wherein the assigning step comprises:

assigning the large item to an elevator with less than a threshold assigned load.

17. The method of claim 13, wherein the first input and the second input are received on a destination entry input device.

18. The method of claim 17, wherein receiving the first input comprises:

receiving a signal when a large item key on the destination entry input device is pressed.

19. The method of claim 17, wherein receiving the first input comprises:

receiving a validation code input on the destination entry input device.

20. The method of claim 13, wherein the determining step comprises:

determining a location of each elevator and a load assigned to each elevator in the group elevator system.
