Abstract

A method of monitoring a conveyance apparatus within a conveyance system including: obtaining a first health level of a conveyance system at a first time; receiving customer feedback regarding operation of the conveyance system proximate the first time from a customer; and adjusting a threshold health level of the conveyance system to be less than or equal to the first health level of the conveyance system in response to the customer feedback.

First claim

What is claimed is:

1. A method of monitoring a conveyance apparatus within a conveyance system, the method comprising:
obtaining a first health level of a conveyance system at a first time;
receiving customer feedback regarding operation of the conveyance system proximate the first time from a customer;
adjusting a threshold health level of the conveyance system to be less than or equal to the first health level of the conveyance system in response to the customer feedback;
obtaining a second health level of a conveyance system at a second time;
determining that the second health level of the conveyance system is less than the threshold health level; and
activating an alert on a mechanic computing device indicating that the second health level for the conveyance system has fallen below the threshold health level.

2. The method of claim 1 , further comprising:
adjusting the threshold health level of the conveyance system to be equal to the first health level.

3. The method of claim 1 , further comprising:
adjusting the threshold health level of the conveyance system to be less than the first health level.

4. The method of claim 1 , further comprising:
determining that the customer was utilizing the conveyance system proximate the first time.

5. The method of claim 1 , wherein obtaining a first health level of a conveyance system at a first time further comprises:
detecting, using a sensing apparatus, at the first time an acceleration of the conveyance apparatus, temperature data of the conveyance system, and pressure data proximate the conveyance apparatus; and
determining the first health level of the conveyance system at the first time in response to at least one of the acceleration of the conveyance apparatus, the temperature data of the conveyance system, and the pressure data proximate the conveyance apparatus.

6. The method of claim 1 , further comprising:
enabling adjustment of the threshold health level of the conveyance system in response to at least one of a country specific threshold, a region specific threshold, a building type threshold, a size of customer portfolio of a customer that owns the conveyance system, a size of contract with the customer that owns the conveyance system, and a potential for future jobs or contracts with the customer that owns the conveyance system.

7. The method of claim 1 , wherein the threshold health level is adjusted only after a selected number of customer feedbacks have been received.

8. The method of claim 1 , wherein the first health level of the conveyance system is obtained at the first time in response to the customer feedback.

9. The method of claim 1 , further comprising:
increasing the threshold health level of the conveyance system after a selected period of time if no additional customer feedback has been received.

10. The method of claim 1 , wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car.

11. The method of claim 1 , wherein the conveyance system is an escalator system and the conveyance apparatus is a moving stairway of the escalator system.

12. A system for monitoring a conveyance apparatus within a conveyance system, the system comprising:
a processor; and
a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
obtaining a first health level of a conveyance system at a first time;
receiving customer feedback regarding operation of the conveyance system proximate the first time from a customer;
adjusting a threshold health level of the conveyance system to be less than or equal to the first health level of the conveyance system in response to the customer feedback;
obtaining a second health level of a conveyance system at a second time;
determining that the second health level of the conveyance system is less than the threshold health level; and
activating an alert on a mechanic computing device indicating that the second health level for the conveyance system has fallen below the threshold health level.

13. The system of claim 12 , wherein the operations further comprise:
adjusting the threshold health level of the conveyance system to be equal to the first health level.

14. The system of claim 12 , wherein the operations further comprise:
adjusting the threshold health level of the conveyance system to be less than the first health level.

15. The system of claim 12 , wherein the operations further comprise:
determining that the customer was utilizing the conveyance system proximate the first time.

16. The system of claim 12 , wherein obtaining a first health level of a conveyance system at a first time further comprises:
detecting, using a sensing apparatus, at the first time an acceleration of the conveyance apparatus, temperature data of the conveyance system, and pressure data proximate the conveyance apparatus; and
determining the first health level of the conveyance system at the first time in response to at least one of the acceleration of the conveyance apparatus, the temperature data of the conveyance system, and the pressure data proximate the conveyance apparatus.

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

18. A computer program product embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:
obtaining a first health level of a conveyance system at a first time;
receiving customer feedback regarding operation of the conveyance system proximate the first time from a customer; and
adjusting a threshold health level of the conveyance system to be less than or equal to the first health level of the conveyance system in response to the customer feedback;
obtaining a second health level of a conveyance system at a second time;
determining that the second health level of the conveyance system is less than the threshold health level; and
activating an alert on a mechanic computing device indicating that the second health level for the conveyance system has fallen below the threshold health level.
