Abstract

A method of operating a dispatcher of an elevator group of a building elevator system having a plurality of elevator systems organized into multiple elevator groups including: receiving an elevator call, the elevator call including a desired destination; transmitting elevator status data from the elevator group to one or more other elevator groups of the building elevator system; receiving elevator status data from each of the one or more other elevator groups of the building elevator system; determining a verdict depicting whether an elevator car of the elevator group is best to serve the elevator call in response to the elevator status data of each of the one or more other elevator groups of the building elevator system; and calling an elevator car in response to the verdict.

First claim

What is claimed is:

1. A method of operating a dispatcher of an elevator group of a building elevator system having a plurality of elevator systems organized into multiple elevator groups, the method comprising:
receiving an elevator call routed from a redirector that received the elevator call, the elevator call including a desired destination;
transmitting elevator status data from the elevator group to one or more other elevator groups of the building elevator system;
receiving elevator status data from each of the one or more other elevator groups of the building elevator system;
determining a verdict depicting whether an elevator car of the elevator group is best to serve the elevator call in response to the elevator status data of each of the one or more other elevator groups of the building elevator system; and
transmitting the verdict to a redirector of the building elevator system, wherein the redirector is configured to call an elevator car in response to the verdict.

2. The method of claim 1 , wherein
the redirector receives the elevator call from a destination entry device in communication with the building elevator system.

3. The method of claim 1 , wherein the verdict indicates that an elevator car of the elevator group is best to answer the elevator call or that an elevator car of the elevator group is not best to answer the elevator call.

4. The method of claim 3 , wherein the method further comprises:
displaying the elevator car of the elevator group that is best to answer the elevator call on the destination entry device.

5. The method of claim 3 , further comprising:
moving the elevator car of the elevator group that is best to answer the elevator call to a landing of the building elevator system to answer the elevator call.

6. The method of claim 1 , wherein the elevator status data is transmitted in response to the elevator call or at selected time intervals.

7. The method of claim 6 , wherein the elevator status data includes at least one of a spare capacity of the elevator group, a source floor's waiting time, a destination floor's service time, whether there is an elevator car available to serve the elevator call immediately, whether the elevator call is already assigned to an elevator car in the elevator group, whether the destination is part of a group of destinations already assigned to the elevator group, building management preferences, a current position of the elevator car, current commitments of the elevator car, a number of stops each passenger assigned to the elevator car will make prior to reaching their destination, how long it will take the elevator car to serve the elevator call, and an impact of adding the elevator call to the elevator car on the other elevator call already assigned to the wait time of the elevator car.

8. A dispatcher of an elevator group of a building elevator system having a plurality of elevator systems organized into multiple elevator groups, the dispatcher comprising:
a processor; and
a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
receiving an elevator call routed from the redirector that received the elevator call, the elevator call including a desired destination;
transmitting elevator status data from the elevator group to one or more other elevator groups of the building elevator system;
receiving elevator status data from each of the one or more other elevator groups of the building elevator system;
determining a verdict depicting whether an elevator car of the elevator group is best to serve the elevator call in response to the elevator status data of each of the one or more other elevator groups of the building elevator system; and
transmitting the verdict to a redirector of the building elevator system, wherein the redirector is configured to call an elevator car in response to the verdict.

9. The dispatcher of claim 8 , wherein
the redirector receives the elevator call from a destination entry device in communication with the building elevator system.

10. The dispatcher of claim 8 , wherein the verdict indicates that an elevator car of the elevator group is best to answer the elevator call or that an elevator car of the elevator group is not best to answer the elevator call.

11. The dispatcher of claim 10 , wherein the operations further comprise:
displaying the elevator car of the elevator group that is best to answer the elevator call on the destination entry device.

12. The dispatcher of claim 10 , further comprising:
moving the elevator car of the elevator group that is best to answer the elevator call to a landing of the building elevator system to answer the elevator call.

13. The dispatcher of claim 8 , wherein the elevator status data is transmitted in response to the elevator call or at selected time intervals.

14. The dispatcher of claim 8 , wherein the elevator status data includes at least one of a spare capacity of the elevator group, a source floor's waiting time, a destination floor's service time, whether there is an elevator car available to serve the elevator call immediately, whether the elevator call is already assigned to an elevator car in the elevator group, whether the destination is part of a group of destinations already assigned to the elevator group, building management preferences, a current position of the elevator car, current commitments of the elevator car, a number of stops each passenger assigned to the elevator car will make prior to reaching their destination, how long it will take the elevator car to serve the elevator call, and an impact of adding the elevator call to the elevator car on the other elevator call already assigned to the wait time of the elevator car.
