Elevator swing operation system and method
An elevator swing operation system for use in a building includes a plurality of floors with landings that are grouped into zones. The elevator cars are allocated to service the zones with a default allocation setup or configuration. The allocation of elevator cars to zones can be modified by moving an elevator car from one zone to another in response to a maximum estimated time to arrival being exceeded and a maximum number of elevator cars allowed to change zones not being exceeded. Furthermore, the default configuration or allocation can be restored when the system is in swing operation, an elevator car is parked, and a minimum time for receiving no calls has been exceeded.
1. An elevator dispatching system for use in a building having a plurality of service areas, a plurality of elevator cars, and an elevator controller, wherein the elevator dispatching system comprises:

b. a second parameter defining a maximum number of the plurality of elevator cars allowed to change between the plurality of service areas; and
c. a third parameter defining a minimum time for receiving no calls for one or more elevator cars of the plurality of elevator cars;
d. wherein a first set of the plurality of elevator cars is designated to service a first service area of the plurality of service areas;
e. wherein a second set of the plurality of elevator cars is designated to service a second service area of the plurality of service areas; and
f. wherein an elevator car from the first set of the plurality of elevator cars is switched to service the second service area in response to the maximum ETA, and the maximum number of the plurality of elevator cars allowed to change between the plurality of service areas.
2. The system of claim 1 , wherein the elevator car from the first set of the plurality of elevator cars is switched to service the second service area when the maximum ETA is exceeded.
3. The system of claim 1 , wherein the elevator car from the first set of the plurality of elevator cars continues to service the first service area when the maximum ETA is not exceeded.
4. The system of claim 1 , wherein the elevator car from the first set of the plurality of elevator cars is switched to service the second service area when the maximum number of the plurality of elevator cars allowed to change is not exceeded.
5. The system of claim 1 , wherein the elevator car from the first set of the plurality of elevator cars is switched to service the second service area when the maximum ETA is exceeded and the maximum number of the plurality of elevator cars allowed to change is not exceeded.
6. The system of claim 5 , wherein a second elevator car from the first set of the plurality of elevator cars is switched to service the second service area when the maximum ETA is exceeded and the maximum number of the plurality of elevator cars allowed to change is not exceeded.
7. The system of claim 1 , wherein the elevator car from the first set of the plurality of elevator cars continues to service the first service area when the maximum number of the plurality of elevator cars allowed to change is exceeded.
8. The system of claim 1 , wherein the elevator car from the first set of the plurality of elevator cars that was switched to service the second service area is returned to service the first service area when the minimum time for receiving no calls is exceeded.
9. The system of claim 1 , wherein the elevator car from the first set of the plurality of elevator cars that was switched to service the second service area continues to service the second service area when the minimum time for receiving no calls is not exceeded.
10. The system of claim 1 , wherein any of the plurality of elevator cars can service any of the plurality of service areas.
11. The system of claim 1 , wherein the first service area includes an observation deck.
12. The system of claim 11 , wherein the second service area includes a private building service area.
13. The system of claim 1 , wherein the building comprises a plurality of floors, wherein each floor comprises a feature to call the elevator car from the plurality of elevator cars.
14. The system of claim 13 , wherein the feature is coupled with the controller, wherein the feature is operable to communicate to the controller the desired destination of a passenger.
15. The system of claim 1 , wherein the system is operable to lower an average wait time of a passenger.
16. An elevator dispatching system for use in a building having a plurality of service areas, a plurality of elevator cars, and an elevator controller, wherein the elevator dispatching system comprises:
a. a first parameter defining a maximum estimated time to arrival (ETA);
b. a second parameter defining a maximum number of the plurality of elevator cars allowed to change between the plurality of service areas; and
c. a third parameter defining a minimum time for receiving no calls for an elevator car of the plurality of elevator cars;
d. wherein a first set of the plurality of elevator cars is designated to service a first service area of the plurality of service areas;
e. wherein a second set of the plurality of elevator cars is designated to service a second service area of the plurality of service areas;
f. wherein an elevator car from the first set of the plurality of elevator cars is switched to service the second service area in response to the maximum ETA being exceeded and the maximum number of the plurality of elevator cars allowed to change between the plurality of service areas not being exceeded; and
g. wherein the elevator car from the first set that was switched is returned to service the first service area in response to the minimum time for receiving no calls being exceeded.
17. The elevator dispatching system of claim 16 , wherein the elevator car from the first set that was switched is returned to service the first service area in further response to an elevator car from the second set being parked.
18. A method for dispatching an elevator car to a landing, wherein the method comprises:
a. designating a first set of elevator cars to service a first zone;
b. designating a second set of elevator cars to service a second zone;
c. switching an elevator car from the first set of elevator cars to service the second zone when a maximum estimated time to arrival (ETA) is exceeded and a maximum number of the plurality of elevator cars allowed to change zones is not exceeded.
19. The method of claim 18 , further comprising returning the switched elevator car to the first zone when a minimum time for receiving no calls is exceeded within the second zone.
20. The method of claim 18 , wherein another elevator car from the first set elevator cars designated to service the first zone is switched to service the second zone until the maximum number of the elevator cars allowed to change between zones is reached.
