Abstract

A component monitoring system for monitoring a component of a conveyance system including a conveyance apparatus including: a camera configured to capture a sequence images of the component, the sequence of images being motion data; and a processor configured to determine an evaluation summary of the component in response to at least the motion data.

First claim

What is claimed is:

1. A component monitoring system for monitoring a component of a conveyance system comprising a conveyance apparatus, the component monitoring system comprising:
a microphone configured to detect sound data of the component;
a camera configured to capture a sequence images of the component, the sequence of images being motion data; and
a processor configured to determine an evaluation summary of the component in response to at least the motion data;
wherein an abnormality is determined in the evaluation summary by linking the sound data with the motion data that occurred at a similar moment in time.

2. The component monitoring system of claim 1 , further comprising:
wherein the evaluation summary is determined in response to the motion data and the sound data.

3. The component monitoring system of claim 2 , wherein at least one of the camera and the microphone is located within a mobile computing device.

4. The component monitoring system of claim 1 , wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car.

5. The component monitoring system of claim 4 , wherein the component is an elevator door.

6. The component monitoring system of claim 1 , wherein at least one of the camera and the microphone is located within the conveyance apparatus.

7. The component monitoring system of claim 1 , wherein at least one of the camera and the microphone is located outside of the conveyance apparatus.

8. A method of monitoring a component of a conveyance system comprising a conveyance apparatus, the method comprising:
detecting sound data of the component using a microphone;
capturing a sequence images of the component using a camera, the sequence of images being motion data; and
determining an evaluation summary of the component in response to at least the motion data;
determining an abnormality in the evaluation summary by linking the sound data with the motion data that occurred at a similar moment in time.

9. The method of claim 8 , wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car.

10. The method of claim 9 , wherein the component is an elevator door.

11. A component monitoring system for monitoring a component of a conveyance system comprising a conveyance apparatus, the component monitoring system comprising:
a device configured to detect motion data of the component;
a microphone configured to sound data of the component; and
a processor configured to determine an evaluation summary of the component in response to the motion data and the sound data;
wherein an abnormality is determined in the evaluation summary by linking the sound data with the motion data that occurred at a similar moment in time.

12. The component monitoring system of claim 11 , wherein the device is a camera configured to capture images of the component, wherein the images are the motion data.

13. The component monitoring system of claim 12 , wherein at least one of the device and the microphone is located within a mobile computing device.

14. The component monitoring system of claim 12 , wherein the device is an inertial measurement unit sensor configured to detect accelerations, wherein the accelerations are the motion data.

15. The component monitoring system of claim 12 , wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car.

16. The component monitoring system of claim 15 , wherein the component is an elevator door.

17. The component monitoring system of claim 11 , wherein at least one of the camera and the microphone is located within the conveyance apparatus.
