Abstract

A building settling detection system having at least one sensor configured between a guide rail track of an elevator system and a pit of the elevator system and a controller in communication with the at least one sensor, the controller configured to monitor an output of the at least one sensor and transmit a notification to a remote location when the output of the at least one sensor meets or exceeds a predetermined threshold indicating that the predetermined threshold is met or exceeded.

First claim

What is claimed is:

1. A building settling detection system comprising:
at least one sensor configured between a guide rail of an elevator system and a pit of the elevator system, wherein the at least one sensor is located between a base material of the guide rail and the pit of the elevator system such that the at least one sensor receives a force from the guide rail, the at least one sensor configured to generate an output based on a received force from the guide rail; and
a controller in communication with the at least one sensor, the controller configured to monitor the output of the at least one sensor and transmit a notification to a remote location when the output of the at least one sensor meets or exceeds a predetermined threshold indicating that the predetermined threshold is met or exceeded.

2. The building settling detection system of claim 1 , wherein at least one sensor of the at least one sensors is a force, displacement, strength, strain, or compression sensor.

3. The building settling detection system of claim 1 , wherein the at least one sensor comprises at least one first sensor between a first guide rail and the pit and at least one second sensor between a second guide rail and the pit.

4. The building settling detection system of claim 3 , wherein the first guide rail is a guide rail of an elevator car and the second guide rail is a guide rail of a counter weight.

5. The building settling detection system of claim 1 , wherein the controller is a controller of the elevator system.

6. The building settling detection system of claim 1 , wherein the threshold is a first threshold and when the output of the at least one sensor exceeds the first threshold, the controller is configured to increase a threshold counter by one to a second threshold and the controller monitors the output of the at least one sensor to determine if the output exceeds the second threshold.

7. The building settling detection system of claim 1 , wherein when the output of the at least one sensor exceeds a maximum threshold, the controller is configured to disable the elevator system.

8. The building settling detection system of claim 1 , wherein the notification is transmitted only when the output of the at least one sensor meets or exceeds the predetermined threshold for longer than a predetermined period of time.

9. A method of monitoring building settling, the method comprising:
monitoring an output of at least one sensor configured between a guide rail of an elevator system and a pit of the elevator system, wherein the at least one sensor is located between a base material of the guide rail and the pit of the elevator system such that the at least one sensor receives a force from the guide rail;
determining if the output of the at least one sensor meets or exceeds a predetermined threshold; and
when the output exceeds the predetermined threshold, transmitting a notification to a remote location indicating the predetermined threshold is met or exceeded.

10. The method of claim 9 , wherein the at least one sensor comprises at least one first sensor between a first guide rail and the pit and at least one second sensor between a second guide rail and the pit.

11. The method of claim 10 , wherein the first guide rail is a guide rail of an elevator car and the second guide rail is a guide rail of a counter weight.

12. The method of claim 9 , wherein the at least one sensor is at least one of a force, displacement, strength, strain, or compression sensor.

13. The method of claim 9 , wherein the process is performed by a controller of the elevator system.

14. The method of claim 9 , wherein the threshold is a first threshold and when the output of the at least one sensor exceeds the first threshold, the method further comprises increasing a threshold counter by one to a second threshold and monitoring the output of the at least one sensor to determine if the output exceeds the second threshold.

15. The method of claim 9 , further comprising disabling the elevator system when a maximum threshold is exceeded by the output of the at least one sensor.

16. A building settling detection system comprising:
at least one sensor configured between a base material of a guide rail of an elevator system and a pit of the elevator system, the at least one sensor configured to receive a force from the guide rail; and
a controller in communication with the at least one sensor, the controller configured to monitor an output of the at least one sensor and transmit a notification to a remote location when the output of the at least one sensor meets or exceeds a predetermined threshold indicating that the predetermined threshold is met or exceeded,
wherein the threshold is a first threshold and when the output of the at least one sensor exceeds the first threshold, the controller is configured to increase a threshold counter by one to a second threshold and the controller monitors the output of the at least one sensor to determine if the output exceeds the second threshold.

17. The building settling detection system of claim 16 , wherein at least one sensor of the at least one sensors is a force, displacement, strength, strain, or compression sensor.

18. The building settling detection system of claim 16 , wherein the at least one sensor comprises at least one first sensor between a first guide rail and the pit and at least one second sensor between a second guide rail and the pit.

19. The building settling detection system of claim 18 , wherein the first guide rail is a guide rail of an elevator car and the second guide rail is a guide rail of a counter weight.

20. The building settling detection system of claim 16 , wherein the controller is a controller of the elevator system.
