Abstract

A method of operating a building elevator system within a building having a plurality of floors including: controlling a building elevator system comprising a first elevator system having a first elevator car and a second elevator system having a second elevator car; determining one or more sectors for the plurality of floors in response to at least one of a time of day, manual input, a density of the down peak traffic, and whether there is simultaneous up peak or inter-floor traffic, the one or more sectors comprising a first sector having a first plurality of floors and a second sector having a second plurality of floors; assigning the first elevator car to the first sector; and assigning the second elevator car to the second sector.

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 building elevator system comprising a first elevator system having a first elevator car and a second elevator system having a second elevator car, wherein the first elevator car and the second elevator car are configured to serve a plurality of floors;
determining one or more sectors for the plurality of floors in response to at least one of a time of day, manual input, a density of the down peak traffic, and whether there is simultaneous up peak or inter-floor traffic, the one or more sectors comprising a first sector having a first plurality of floors and a second sector having a second plurality of floors;
assigning the first elevator car to the first sector, the first elevator car being configured to transport passengers from the first sector to a first selected floor of the plurality of floors;
assigning the second elevator car to the second sector, the second elevator car being configured to transport passengers from the second sector to a second selected floor of the plurality of floors,
receiving an elevator call from a floor of the first plurality of floors within the first sector;
determining that the first elevator car assigned to the first sector will not arrive at the floor of the first plurality of floors within the first sector within a first selected time period;
determining that a second elevator car will arrive at the floor of the first plurality of floors within the first sector within a first selected time period; and
moving the second elevator car to the floor of the first plurality of floors within the first sector.

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

3. The method of claim 2 , further comprising:
receiving an elevator call from a floor of the second plurality of floors within the second sector; and
moving the second elevator car to the floor of the second plurality of floors within the second sector.

4. The method of claim 1 , wherein the second selected floor is the first selected floor.

5. The method of claim 4 , wherein the first selected floor is an exit floor.

6. The method of claim 1 , wherein the second plurality of floors does not include any floors within the first plurality of floors.

7. The method of claim 1 , wherein the second plurality of floors includes at least one floor within the first plurality of floors.

8. The method of claim 1 , wherein the first plurality of floors includes contiguous floors of the plurality of floors.

9. The method of claim 1 , wherein the first plurality of floors includes non-contiguous floors of the plurality of floors.

10. The method of claim 1 , further comprising:
receiving an elevator call from a floor of the first plurality of floors within the first sector;
determining that the first elevator car assigned to the first sector is not eligible to be assigned to the elevator call;
determining that a second elevator car is eligible to be assigned to the elevator call; and
moving the second elevator car to the floor of the first plurality of floors within the first sector.

11. The method of claim 10 , wherein the first elevator car is ineligible due to an opposite stop condition.

12. The method of claim 1 , further comprising:
moving the first elevator car through the first sector during a single trip;
detecting a number of elevator stops made by the first elevator car during the single trip; and
extending the first sector by a selected number of floors as the first elevator car moves through the first sector when the number of elevator stops is less than a selected number of elevator stops.

13. The method of claim 1 , further comprising:
moving the first elevator car through the first sector during a single trip;
determining a reversal point of the first elevator car; and
extending the first sector by a selected number of floors as the first elevator car moves through the first sector in response to the reversal point of the first elevator car.

14. The method of claim 12 , wherein the first elevator car is moving downward through the first sector.

15. A control system of a building elevator system comprising:
a processor;
a memory comprising computer-executable instructions that, when executed by
the processor, cause the processor to perform operations, the operations comprising:
controlling a building elevator system comprising a first elevator system having a first elevator car and a second elevator system having a second elevator car, wherein the first elevator car and the second elevator car are configured to serve a plurality of floors;
determining one or more sectors for the plurality of floors in response to at least one of a time of day, manual input, a density of the down peak traffic, and whether there is simultaneous up peak or inter-floor traffic, the one or more sectors comprising a first sector having a first plurality of floors and a second sector having a second plurality of floors;
assigning the first elevator car to the first sector, the first elevator car being configured to transport passengers from the first sector to a first selected floor of the plurality of floors;
assigning the second elevator car to the second sector, the second elevator car being configured to transport passengers from the second sector to a second selected floor of the plurality of floors;
receiving an elevator call from a floor of the first plurality of floors within the first sector;
determining that the first elevator car assigned to the first sector will not arrive at the floor of the first plurality of floors within the first sector within a first selected time period;
determining that a second elevator car will arrive at the floor of the first plurality of floors within the first sector within a first selected time period; and
moving the second elevator car to the floor of the first plurality of floors within the first sector.

16. The control system of claim 15 , wherein the operations further comprise:
receiving an elevator call from a floor of the first plurality of floors within the first sector; and
moving the first elevator car to the floor of the first plurality of floors within the first sector.

17. The control system of claim 16 , wherein the operations further comprise:
receiving an elevator call from a floor of the second plurality of floors within the second sector; and
moving the second elevator car to the floor of the second plurality of floors within the second sector.

18. The control system of claim 15 , wherein the second selected floor is the first selected floor.

19. The control system of claim 18 , wherein the first selected floor is an exit floor.

20. A method of operating a building elevator system within a building having a plurality of floors, the method comprising:
controlling a building elevator system comprising a first elevator system having a first elevator car and a second elevator system having a second elevator car, wherein the first elevator car and the second elevator car are configured to serve a plurality of floors;
determining one or more sectors for the plurality of floors in response to at least one of a time of day, manual input, a density of the down peak traffic, and whether there is simul
