Abstract

An illustrative example method of controlling an elevator system includes receiving a first request for elevator service from a requestor, receiving a second request for elevator service from the requestor while the first request is still pending, and controlling the elevator system to provide elevator service for only one of the first request or the second request.

First claim

I claim:

1. A method of controlling an elevator system, the method comprising:
receiving a first request for elevator service from a requestor;
receiving a second request for elevator service from the requestor while the first request is still pending;
assigning an elevator car to service the first request before receiving the second request; and
controlling the elevator system to provide elevator service for only one of the first request or the second request; and

determining whether the first request is still pending when receiving the second request by determining whether elevator car assigned to service the first request has arrived at a boarding location of the requestor.

2. The method of claim 1 , comprising
determining whether the first request or the second request corresponds to a desired elevator service of the requestor; and
controlling the elevator system to provide the desired elevator service of the requestor.

3. A method of controlling an elevator system, the method comprising:
receiving a first request for elevator service from a requestor;
receiving a second request for elevator service from the requestor while the first request is still pending;
controlling the elevator system to provide elevator service for only one of the first request or the second request;
determining whether the first request or the second request corresponds to a desired elevator service of the requestor; and

controlling the elevator system to provide the desired elevator service of the requestor, wherein the determining comprises
determining whether the elevator service of the second request is different than the elevator service of the first request; and
either
identifying the first request as the request that corresponds to the desired elevator service when the elevator service of the second request is the same as the elevator service of the pending request,
or
obtaining additional input from the requestor identifying the desired elevator service.

4. The method of claim 3 , wherein obtaining additional input from the requestor comprises
prompting the requestor to indicate a selection of the elevator service of the first request or the elevator service of the second request; and
determining the desired elevator service based on the requestor making the selection.

5. The method of claim 3 , wherein the elevator service of the second request is the same as the elevator service of the first request and the method comprises providing a confirmation for the requestor that confirms at least one characteristic of the first request.

6. The method of claim 5 , wherein the at least one characteristic includes an indication of a destination and an indication of an elevator car assigned to the first request.

7. A method of controlling an elevator system, the method comprising:
receiving a first request for elevator service from a requestor;
receiving a second request for elevator service from the requestor while the first request is still pending;
controlling the elevator system to provide elevator service for only one of the first request or the second request;
determining whether the first request or the second request corresponds to a desired elevator service of the requestor; and

controlling the elevator system to provide the desired elevator service of the requestor, wherein the determining comprises
prompting the requestor to select the elevator service corresponding to the second request or the first request; and
determining which elevator service the requestor selects in response to the prompting.

8. The method of claim 7 , wherein the elevator service of the second request is different than the elevator service of the first request.

9. The method of claim 1 , wherein the second request is submitted subsequent to the first request by the same requestor while the first request is pending.

10. An elevator system, comprising:
at least one input device configured to receive requests for elevator service; and
an elevator controller that is configured to
determine that the at least one input device has received a first request for elevator service from a requestor;
determine that the at least one input device has received a second request for elevator service from the requestor while the first request is still pending; and
control the elevator system to provide elevator service for only one of the first request or the second request;
wherein the elevator controller is configured to determine whether the first request or the second request corresponds to a desired elevator service of the requestor, and control the elevator system to provide the desired elevator service of the requestor; and
wherein the elevator controller is configured to determine the desired elevator service by prompting the requestor through the at least one input device to select the elevator service corresponding to the second request or the first request, and determining which elevator service the requestor selects in response to the prompting.

11. The elevator system of claim 10 , wherein the elevator controller is configured to
determine whether the first request or the second request corresponds to the desired elevator service of the requestor; and
control the elevator system to provide the desired elevator service of the requestor.

12. The elevator system of claim 10 , wherein the elevator service of the second request is different than the elevator service of the first request.

13. The elevator system of claim 10 , wherein the elevator controller is configured to
identify the requestor of the first and second request, respectively, based on identification information associated with the first and second request, respectively; and
receive the identification information as a prerequisite to the requestor being able to make the first request and the second request, respectively.

14. The elevator system of claim 13 , wherein the elevator controller is configured to
assign an elevator car to service the first request before receiving the second request; and
determine whether the first request is still pending when receiving the second request by determining whether elevator car assigned to service the first request has arrived at a boarding location of the requestor.

15. The elevator system of claim 10 , wherein the second request is submitted subsequent to the first request by the same requestor while the first request is pending.

16. An elevator system, comprising:
at least one input device configured to receive requests for elevator service; and
an elevator controller that is configured to
determine that the at least one input device has received a first request for elevator service from a requestor;
determine that the at least one input device has received a second request for elevator service from the requestor while the first request is still pending; and
control the elevator system to provide elevator service for only one of the first request or the second request;
wherein the elevator controller is configured to
determine whether the first request or the second request corresponds to a desired elevator service of the requestor;

control the elevator system to provide the desired elevator service of the requestor;
determine whether the elevator service of the second request is different than the elevator service of the first request; and
either
identify the first request as the request that corresponds to the desired elevator service when the elevator service of the second request is the same as the elevator service of the pending request,
or
obtain
