Abstract

A method of operating a building elevator system within a building having a plurality of floors is provided. The method including: controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further include a first elevator car; controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further include a second elevator car; monitoring usage of the first elevator group and second elevator group; and reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to usage of the first elevator group and usage of the second elevator group.

First claim

What is claimed is:

1. A method of operating a building elevator system within a building having a plurality of floors, the method comprising:
controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further comprise a first elevator car;
controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further comprise a second elevator car;
monitoring usage of the first elevator group;
monitoring usage of the second elevator group;
reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to the usage of the first elevator group and the usage of the second elevator group;
determining a pattern in the usage of the first elevator group using machine learning over a period of time defining a learning period; and
detecting an occurrence of the pattern in the usage of the first elevator group using machine learning,
wherein the one or more elevator systems of the second elevator group is reassigned to the first elevator group when the occurrence of the pattern is detected.

2. The method of claim 1 , wherein the second elevator car is reassigned to first elevator group, and wherein the method further comprises:
receiving an elevator call from a floor of the plurality of floors within the first sector; and
moving the second elevator car to the floor of the plurality of floors within the first sector.

3. The method of claim 1 , wherein monitoring usage of the first elevator group further comprises:
detecting at least one of a number of passengers using the one or more elevator systems of the first elevator group and a number of elevator calls received by the one or more elevator systems of the first elevator group.

4. The method of claim 3 , wherein the number of passengers is detected using visual recognition to identify individual passengers.

5. The method of claim 1 , wherein the at least one of the one or more elevator systems of the second elevator group is reassigned to the first elevator group in response to the usage of the first elevator group and the usage of the second elevator group and the time of day.

6. The method of claim 5 , wherein the at least one of the one or more elevator systems of the second elevator group is reassigned to the first elevator group for a selected period of time.

7. A control system of a building elevator system 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:
controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further comprise a first elevator car;
controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further comprise a second elevator car;
monitoring usage of the first elevator group;
monitoring usage of the second elevator group;
reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to the usage of the first elevator group and the usage of the second elevator group;
determining a pattern in the usage of the first elevator group using machine learning over a period of time defining a learning period; and
detecting an occurrence of the pattern in the usage of the first elevator group using machine learning;
wherein the one or more elevator systems of the second elevator group is reassigned to the first elevator group when the occurrence of the pattern is detected.

8. The control system of claim 7 , wherein the second elevator car is reassigned to first elevator group, and wherein the operations further comprise:
receiving an elevator call from a floor of the plurality of floors within the first sector; and moving the second elevator car to the floor of the plurality of floors within the first sector.

9. The control system of claim 7 , wherein monitoring usage of the first elevator group further comprises:
detecting at least one of a number of passengers using the one or more elevator systems of the first elevator group and a number of elevator calls received by the one or more elevator systems of the first elevator group.

10. The control system of claim 9 , wherein the number of passengers is detected using visual recognition to identify individual passengers.

11. The control system of claim 7 , wherein the at least one of the one or more elevator systems of the second elevator group is reassigned to the first elevator group in response to the usage of the first elevator group and the usage of the second elevator group and the time of day.

12. The control system of claim 11 , wherein the at least one of the one or more elevator systems of the second elevator group is reassigned to the first elevator group for a selected period of time.

13. A computer program product tangibly embodied on a computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:
controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further comprise a first elevator car;
controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further comprise a second elevator car;
monitoring usage of the first elevator group; monitoring usage of the second elevator group; and
reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to the usage of the first elevator group and the usage of the second elevator group;
determining a pattern in the usage of the first elevator group using machine learning over a period of time defining a learning period; and
detecting an occurrence of the pattern in the usage of the first elevator group using machine learning;
wherein the one or more elevator systems of the second elevator group is reassigned to the first elevator group when the occurrence of the pattern is detected.

14. The computer program product of claim 13 , wherein the second elevator car is reassigned to first elevator group, and wherein the operations further comprise:
receiving an elevator call from a floor of the plurality of floors within the first sector; and moving the second elevator car to the floor of the plurality of floors within the first sector.

15. The computer program product of claim 13 , wherein monitoring usage of the first elevator group further comprises:
detecting at least one of a number of passengers using the one or more elevator systems of the first elevator group and a number of elevator calls received by the one or more elevator systems of the first elevator group.

16. The computer program product of claim 15 , wherein the number of passengers is detected using visual recognition to identify individual passengers.
