Abstract

Systems and methods floor bypass in an elevator system are provided. Aspects includes receiving, by the first controller, a first elevator destination call to a first floor, wherein the first destination call causes a first elevator car to dispatch to the first floor. First sensor data associated with a first passenger area associated with the first elevator car is collected, from the first sensor. A presence of a passenger in the first passenger area is detected based at least in part on the first sensor data. And the first elevator car is operated based on the presence of the passenger in the first passenger area.

First claim

What is claimed is:

1. An elevator system comprising:
a first elevator car of a first elevator group and a second elevator car of a second elevator group;
a first sensor operable to collect first sensor data associated with a first passenger area for the first elevator car and a second sensor operable to collect second sensor data associated with a second passenger area for the second elevator car;
a first controller coupled to a first memory, the first controller configured to operate the first elevator car and further configured to:
receive a first elevator destination call to a first floor, wherein the first elevator destination call causes the controller to dispatch the first elevator car to the first floor;
determine a presence of a passenger in the first passenger area based at least in part on the first sensor data; and
operate the first elevator car based on the presence of the passenger in the first passenger area;
the elevator system further comprising:

a second controller coupled to a second memory, the second controller configured to operate the second elevator car and further configured to:
receive a second elevator destination call to the first floor, wherein the second elevator destination call causes the second elevator car to dispatch to the first floor;
determine a presence of the passenger in the second passenger area based at least in part on the second sensor data; and
operate the second elevator car based on the presence of the passenger in the second passenger area;

wherein the first passenger area comprises one or more locations proximate to the first elevator car;
wherein the second passenger area comprises one or more locations proximate to the second elevator car;
wherein the first passenger area overlaps with the second passenger area.

2. The elevator system of claim 1 , wherein the first controller is further configured to cancel the first elevator destination call based at least in part on a determination the passenger has exited the first passenger area for greater than a first threshold amount of time.

3. The elevator system of claim 1 , wherein the second controller is further configured to cancel the second elevator destination call based at least in part on a determination the passenger has exited the second passenger area for greater than a second threshold amount of time.

4. The elevator system of claim 1 , wherein the first sensor and second sensor comprise at least one of a camera or Doppler effect sensor.

5. The elevator system of claim 2 , wherein the first controller is further configured to:
responsive to cancelling the first elevator destination call, operate the first elevator car to proceed to a next elevator destination call.

6. A method for floor bypass in an elevator system, the elevator system comprising a first elevator car of a first elevator group, a first sensor, a first controller, a second elevator car of a first elevator group, a second sensor and a second controller, the method comprising:
receiving, by the first controller, a first elevator destination call to a first floor, wherein the first destination call causes the first elevator car to dispatch to the first floor;
collecting first sensor data, from the first sensor, associated with a first passenger area associated with the first elevator car;
determining a presence of a passenger in the first passenger area based at least in part on the first sensor data; and
operating the first elevator car based on the presence of the passenger in the first passenger area;
the method further comprising:
receiving, by the second controller, a second elevator destination call to the first floor, wherein the second destination call causes the second elevator car to dispatch to the first floor;
collecting second sensor data, from the second sensor, associated with a second passenger area associated with the second elevator car
determine a presence of a passenger in the second passenger area based at least in part on the second sensor data; and
operating the second elevator car based on the presence of the passenger in the second passenger area;
wherein the first passenger area comprises one or more locations proximate to the first elevator car;
wherein the second passenger area comprises one or more locations proximate to the second elevator car;
wherein the first passenger area overlaps with the second passenger area.

7. The method of claim 6 further comprising cancelling the first elevator destination call based at least in part on a determination the passenger has exited the first passenger area for greater than a first threshold amount of time.

8. The method of claim 6 further comprising cancelling the second elevator destination call based at least in part on a determination the passenger has exited the second passenger area for greater than a second threshold amount of time.

9. The method of claim 6 , wherein the first sensor and second sensor comprise at least one of a camera or Doppler effect sensor.

10. The method of claim 7 further comprising responsive to cancelling the first elevator destination call, operating the first elevator car to proceed to a next elevator destination call.
