Abstract

A method of operating a shuttle elevator group including: detecting an arrival of an elevator car at a landing; determining a time since a previous elevator car departed the landing; determining a fullness percentage of the elevator car; determining an estimated time until a next elevator car arrives at the landing; and determining when the elevator car departs the landing based upon at least one of the fullness percentage of the elevator car, the time since the previous elevator car departed the landing, and the estimated time until the next elevator car arrives at the landing.

First claim

What is claimed is:

1 . A method of operating a shuttle elevator group, the method comprising:
detecting an arrival of an elevator car at a landing; determining a time since a previous elevator car departed the landing; determining a fullness percentage of the elevator car; determining an estimated time until a next elevator car arrives at the landing; and determining when the elevator car departs the landing based upon at least one of the fullness percentage of the elevator car, the time since the previous elevator car departed the landing, and the estimated time until the next elevator car arrives at the landing.

2 . The method of claim 1 , further comprising:
detecting a number of passengers within the elevator car, wherein the fullness percentage of the elevator car is determined in response to the number of passengers within the elevator car.

3 . The method of claim 1 , further comprising:
commanding the elevator car to the depart the landing when the fullness percentage of the elevator car is greater than a selected fullness percentage.

4 . The method of claim 1 , further comprising:
commanding the elevator car to the depart the landing when the time since the previous elevator car departed the landing is greater than a selected period of time.

5 . The method of claim 1 , further comprising:
commanding the elevator car to the depart the landing when the estimated time until the next elevator car arrives at the landing is less than a selected period of time.

6 . The method of claim 1 , further comprising:
commanding the elevator car to the depart the landing when the fullness percentage of the elevator car is greater than a selected fullness percentage; commanding the elevator car to the depart the landing when the time since the previous elevator car departed the landing is greater than a selected period of time; and commanding the elevator car to the depart the landing when the estimated time until the next elevator car arrives at the landing is less than a selected period of time.

7 . The method of claim 1 , further comprising:
obtaining a layout of a physical location of two or more elevator systems within an elevator lobby at the landing, each of the two or more elevator systems including an elevator car; and coordinating arrival of the elevator car of each of the two or more elevator systems at the landing in response to the physical location of the two or more elevator systems within the elevator lobby, wherein the two or more elevator systems are organized in an arrangement within the elevator lobby.

8 . A method of operating a shuttle elevator group, the method comprising:
obtaining a layout of a physical location of two or more elevator systems within an elevator lobby at a landing, each of the two or more elevator systems including an elevator car; and coordinating arrival of the elevator car of each of the two or more elevator systems at the landing in response to the physical location of the two or more elevator systems within the elevator lobby, wherein the two or more elevator systems are organized in an arrangement within the elevator lobby.

9 . The method of claim 8 , further comprising:
coordinating arrival of the elevator car of each of the two or more elevator systems such that elevator car arrives from each of the two or more elevator systems in a clockwise order around the arrangement.

10 . The method of claim 8 , further comprising:
coordinating arrival of the elevator car of each of the two or more elevator systems such that elevator car arrives from each of the two or more elevator systems in a counter clockwise order around the arrangement.

11 . The method of claim 8 , further comprising:
organizing the two or more elevator systems into a first group and a second group within the elevator lobby.

12 . The method of claim 11 , further comprising:
deactivating the first group, such that the two or more elevator system organized in the first group are no longer called to the landing.

13 . The method of claim 11 , wherein the first group is located on first side of the elevator lobby and the second group is located on second side of the elevator lobby.

14 . A computer program product embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:
detecting an arrival of an elevator car at a landing; determining a time since a previous elevator car departed the landing; determining a fullness percentage of the elevator car in response to the number of passengers within the elevator car; determining an estimated time until a next elevator car arrives at the landing; and determining when the elevator car departs the landing based upon at least one of the fullness percentage of the elevator car, the time since the previous elevator car departed the landing, and the estimated time until the next elevator car arrives at the landing.

15 . The computer program product of claim 14 , wherein the operations further comprise:
detecting a number of passengers within the elevator car, wherein the fullness percentage of the elevator car is determined in response to the number of passengers within the elevator car.

16 . The computer program product of claim 14 , wherein the operations further comprise:
commanding the elevator car to the depart the landing when the fullness percentage of the elevator car is greater than a selected fullness percentage.

17 . The computer program product of claim 14 , wherein the operations further comprise:
commanding the elevator car to the depart the landing when the time since the previous elevator car departed the landing is greater than a selected period of time.

18 . The computer program product of claim 14 , wherein the operations further comprise:
commanding the elevator car to the depart the landing when the estimated time until the next elevator car arrives at the landing is less than a selected period of time.

19 . The computer program product of claim 14 , wherein the operations further comprise:
commanding the elevator car to the depart the landing when the fullness percentage of the elevator car is greater than a selected fullness percentage; commanding the elevator car to the depart the landing when the time since the previous elevator car departed the landing is greater than a selected period of time; and commanding the elevator car to the depart the landing when the estimated time until the next elevator car arrives at the landing is less than a selected period of time.

20 . The computer program product of claim 14 , wherein the operations further comprise:
obtaining a layout of a physical location of two or more elevator systems within an elevator lobby at the landing, each of the two or more elevator systems including an elevator car; and coordinating arrival of the elevator car of each of the two or more elevator systems at the landing in response to the physical location of the two or more elevator systems within the elevator lobby, wherein the two or more elevator systems are organized in an arrangement within the elevator lobby.
