Abstract

Systems and methods for assessing the health of a first apparatus by monitoring a second apparatus are described herein. A method for monitoring a health of a first apparatus may comprise receiving a performance parameter from a second apparatus, wherein performance of the second apparatus is dependent upon the health of the first apparatus, assessing the performance parameter, and determining the health of the first apparatus. In various embodiments, the performance parameter may comprise at least one of a speed value of the second apparatus, a position value of the second apparatus, a temperature value of the second apparatus, or a time value of the second apparatus.

Claims

1. A method for assessing a health of a first apparatus, comprising:

receiving a performance parameter from a second apparatus, wherein a performance of the second apparatus is dependent upon the health of the first apparatus;

assessing the performance parameter; and

determining the health of the first apparatus.

2. The method of claim 1, wherein the first apparatus comprises at least one of a pump or a generator.

3. The method of claim 1, wherein the second apparatus comprises at least one of an actuator or an electric motor.

4. The method of claim 1, wherein the performance parameter comprises at least one of a speed value of the second apparatus, a position value of the second apparatus, a temperature value of the second apparatus, and a time value of the second apparatus.

5. The method of claim 1, wherein the assessing the performance parameter comprises trending the performance parameter to determine the health of the first apparatus.

6. The method of claim 5, wherein the trending the performance parameter is to determine a degradation of the health of the first apparatus.

7. The method of claim 1, wherein the first apparatus is unmonitored.

8. The method of claim 1, wherein the assessing the performance parameter comprises at least one of:

assessing a health of the second apparatus; and

assessing the performance of the second apparatus.

9. The method of claim 1, wherein the determining the health of the first apparatus comprises generating a prognosis of the health of the first apparatus.

10. An article of manufacture, comprising:

a controller; and

a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations, comprising;

receiving, by the controller, a performance parameter from a second apparatus, wherein a performance of the second apparatus is dependent upon a health of a first apparatus;

assessing, by the controller, the performance parameter; and

determining, by the controller, the health of the first apparatus.

11. The article of manufacture of claim 10, wherein the first apparatus comprises at least one of a pump or a generator.

12. The article of manufacture of claim 10, wherein the second apparatus comprises at least one of an actuator or an electric motor.

13. The article of manufacture of claim 10, wherein the performance parameter comprises at least one of a speed value of the second apparatus, a position value of the second apparatus, a temperature value of the second apparatus, and a time value of the second apparatus.

14. The article of manufacture of claim 10, wherein the assessing comprises trending, by the controller, the performance parameter to determine the health of the first apparatus.

15. The article of manufacture of claim 14, wherein the trending the performance parameter is to determine a degradation of the health of the first apparatus.

16. The article of manufacture of claim 10, wherein the first apparatus is unmonitored.

17. The article of manufacture of claim 10, wherein the assessing comprises at least one of:

assessing, by the controller, the performance of the second apparatus; and

assessing, by the controller, a health of the second apparatus.

18. The article of manufacture of claim 10, wherein the determining the health of the first apparatus comprises generating, by the controller, a prognosis of the health of the first apparatus.

19. A method for monitoring a health of a first unmonitored apparatus, comprising:

assessing a performance of a second monitored apparatus, the second monitored apparatus operatively coupled to the first unmonitored apparatus, the performance of the second monitored apparatus being dependent on the first unmonitored apparatus.

20. The method of claim 19, wherein the assessing the performance of the second monitored apparatus comprises at least one of:

receiving a performance parameter from the second monitored apparatus, wherein the performance of the second monitored apparatus is dependent on the health of the first unmonitored apparatus;

assessing the performance parameter; and

determining the health of the first apparatus.
