Abstract

Provided are embodiments for method performing elevator condition-based maintenance using an in-car camera. The method includes monitoring one or more conditions of an elevator system, and analyzing image data obtained from monitoring one or more conditions of the elevator system. The method also includes validating the one or more conditions of the elevator system, and executing an action based on the validation of the one or more conditions. Also provided are embodiments for a system for implementing the method described herein.

First claim

What is claimed is:

1. A system comprising:
a camera system configured to obtain image data; and
a processor, wherein the processor is in communication with the camera system and provides image data to the processor, wherein the processor is configured to:
monitor one or more conditions of an elevator system;
analyze the image data from the camera system;
validate the one or more conditions of the elevator system based on the image data; and
execute an action based on the validation of the one or more conditions;
wherein the processor is configured to remove false alarm information based on the validation of the one or more conditions of the elevator car.

2. The system of claim 1 , further comprising a controller configured to control the elevator system and provide state information to the processor.

3. The system of claim 2 , wherein the processor is configured to compare the image data and indicators in the elevator system based on the state information of the elevator system; and
validate, using image analysis, the state of the elevator system based at least in part on the comparison.

4. The system of claim 1 , wherein the processor is configured to generate at least one of a traffic patterning model or a maintenance model after removing the false alarm information.

5. The system of claim 1 , wherein the processor is configured to perform presence detection to detect at least one of an object or a passenger in the elevator system; and
provide an alarm based at least in part on the presence detection.

6. The system of claim 1 , wherein the action includes an output of the camera system that provides a command to adjust an elevator door dwell time or an elevator door speed based on identifying an object or user type.

7. The system of claim 1 , wherein the action includes an output of the camera system providing a command to the elevator system to assign elevator cars based on a number of users on one or more elevator cars of the elevator system.

8. The system of claim 1 , wherein monitoring the one or more conditions includes monitoring at least one of button operations of an elevator car, a cabin operating panel, a direction of an elevator car, a number of runs of an elevator car, door cycles and door reversals of an elevator car using the camera system.

9. A method for performing condition-based maintenance using a camera, the method comprising:
monitoring one or more conditions of an elevator system;
analyzing the image data from the camera system;
validating the one or more conditions of the elevator system based on the image data; and
executing an action based on the validation of the one or more conditions;
removing false alarm information based on the validation of the one or more conditions of the elevator car.

10. The method of claim 9 , further comprising controlling, using a controller, the elevator system and provide state information to the processor.

11. The method of claim 10 , further comprising comparing the image data and indicators in the elevator system based on the state information of the elevator system; and
validating the state information of the elevator system based at least in part on the comparison.

12. The method of claim 11 , further comprising generating at least one of a traffic patterning model or a maintenance model after removing the false alarm information.

13. The method of claim 9 , further comprising performing presence detection to detect at least one of an object or a passenger in the elevator system; and
providing an alarm based at least in part on the presence detection.

14. The method of claim 13 , wherein the alarm is a left baggage alarm.

15. The method of claim 9 , wherein the action includes at least one of performing condition-based maintenance or monitoring the performance of the elevator system.

16. The method of claim 9 , wherein the action includes an output of the camera system provides a command to adjust an elevator door dwell time or an elevator door speed based on identifying an object or user type.

17. The method of claim 9 , wherein the action includes an output of the camera system that provides a command to the elevator system to assign elevator cars based on a number of users on one or more elevator cars of the elevator system.

18. The method of claim 9 , wherein monitoring the one or more conditions includes monitoring at least one of button operations of an elevator car, a cabin operating panel, a direction of an elevator car, a number of runs of an elevator car, door cycles and door reversals of an elevator car using the camera system.

19. A system comprising:
a camera system configured to obtain image data; and
a processor, wherein the processor is in communication with the camera system and provides image data to the processor, wherein the processor is configured to:
monitor one or more conditions of an elevator system;
analyze the image data from the camera system;
validate the one or more conditions of the elevator system based on the image data; and
execute an action based on the validation of the one or more conditions;

wherein the action includes at least one of performing condition-based maintenance or monitoring the performance of the elevator system.
