Abstract

According to an aspect, an elevator sensor calibration system includes one or more sensors operable to monitor an elevator system, an elevator sensor calibration device, and a computing system. The computing system includes a memory and a processor that collects a plurality of baseline sensor data from the one or more sensors during movement of an elevator component, collects a plurality of disturbance data from the one or more sensors while the elevator component is displaced responsive to contact with the elevator sensor calibration device during movement of the elevator component, and performs analytics model calibration to calibrate a trained model based on one or more response changes between the baseline sensor data and the disturbance data.

First claim

What is claimed is:

1. An elevator sensor calibration system comprising:
one or more sensors operable to monitor an elevator system;
an elevator sensor calibration device; and
a computing system comprising a memory and a processor that collects a plurality of baseline sensor data from the one or more sensors during movement of an elevator component, collects a plurality of experimental data from the one or more sensors while the elevator component is displaced to follow a modified path defined by the elevator sensor calibration device responsive to the elevator component making physical contact with the elevator sensor calibration device during movement of the elevator component, and performs calibration of a trained model based on the experimental data, wherein the trained model establishes a fault designation of operation of the elevator system.

2. The elevator sensor calibration system of claim 1 , wherein multiple movement speed profiles are applied to modify a rate of movement while collecting the baseline sensor data and the experimental data.

3. The elevator sensor calibration system of claim 1 , wherein more than one instance of the elevator sensor calibration device is contacted during movement of the elevator component.

4. The elevator sensor calibration system of claim 1 , wherein the elevator sensor calibration device is sized to induce a first vibration profile upon impact between a first portion of the elevator sensor calibration device and the elevator component and to induce a second vibration profile upon impact between a second portion of the elevator sensor calibration device and the elevator component.

5. The elevator sensor calibration system of claim 1 , wherein the elevator sensor calibration device comprises a rise ramp and a return ramp, and a first angle of the rise ramp is different from a second angle of the return ramp relative to a base portion of the elevator sensor calibration device.

6. The elevator sensor calibration system of claim 1 , wherein the elevator component is a gib, and the elevator sensor calibration device is coupled to a sill comprising a sill groove that retains the gib to guide horizontal motion of an elevator door.

7. The elevator sensor calibration device system of claim 6 , wherein the elevator sensor calibration device contacts an elevated portion of the sill when coupled to the sill and positioned to impact the gib.

8. The elevator sensor calibration system of claim 6 , wherein the elevator sensor calibration device fits at least partially within the sill groove when coupled to the sill and positioned to impact the gib.

9. The elevator sensor calibration system of claim 1 , wherein the elevator component is a roller, and the elevator sensor calibration device is coupled to a door motion guidance track that guides horizontal motion of an elevator door hung by the roller on the door motion guidance track.

10. The elevator sensor calibration system of claim 9 , wherein the elevator sensor calibration device wraps at least partially around the door motion guidance track.

11. A method comprising:
collecting, by a computing system, a plurality of baseline sensor data from one or more sensors during movement of an elevator component of an elevator system;
collecting, by the computing system, a plurality of experimental data from the one or more sensors while the elevator component is displaced to follow a modified path defined by an elevator sensor calibration device responsive to the elevator component making physical contact with the elevator sensor calibration device during movement of the elevator component; and
performing, by the computing system, calibration of a trained model based on the experimental data, wherein the trained model establishes a fault designation of operation of the elevator system.

12. The method of claim 11 , further comprising:
applying multiple movement speed profiles to modify a rate of movement while collecting the baseline sensor data and the experimental data.

13. The method of claim 11 , wherein more than one instance of the elevator sensor calibration device are contacted during movement of the elevator component.

14. The method of claim 11 , wherein the elevator sensor calibration device is sized to induce a first vibration profile upon impact between a first portion of the elevator sensor calibration device and the elevator component and to induce a second vibration profile upon impact between a second portion of the elevator sensor calibration device and the elevator component.

15. The method of claim 11 , wherein the elevator sensor calibration device comprises a rise ramp and a return ramp, and a first angle of the rise ramp is different from a second angle of the return ramp relative to a base portion of the elevator sensor calibration device.

16. The method of claim 11 , wherein the elevator component is a gib, and the elevator sensor calibration device is coupled to a sill comprising a sill groove that retains the gib to guide horizontal motion of an elevator door.

17. The method of claim 16 , wherein the elevator sensor calibration device contacts an elevated portion of the sill when coupled to the sill and positioned to impact the gib.

18. The method of claim 16 , wherein the elevator sensor calibration device fits at least partially within the sill groove when coupled to the sill and positioned to impact the gib.

19. The method of claim 11 , wherein the elevator component is a roller, and the elevator sensor calibration device is coupled to a door motion guidance track that guides horizontal motion of an elevator door hung by the roller on the door motion guidance track.

20. The method of claim 19 , wherein the elevator sensor calibration device wraps at least partially around the door motion guidance track.
