Abstract

Systems and methods for monitoring a pump and a fan are disclosed. A monitoring system for a pump may include an industrial system including a pump, a data acquisition circuit to interpret a plurality of detection values corresponding to at least one of a plurality of input sensors operationally coupled to the pump and communicatively coupled to the data acquisition circuit. A monitoring system may further include a signal evaluation circuit including a timer circuit to generate at least one timing signal and a phase detection circuit structured to determine a relative phase difference between at least one of the detection values and at least one of the timing signals from the timer circuit. A response circuit may perform at least one operation in response to the relative phase difference.

Claims (53)

1. A monitoring system for a pump, the system comprising:

an industrial system comprising the pump;

a data acquisition circuit structured to interpret a plurality of detection values, each of the plurality of detection values corresponding to at least one of a plurality of input sensors operationally coupled to the pump and communicatively coupled to the data acquisition circuit;

a signal evaluation circuit comprising:

a timer circuit structured to generate at least one timing signal; and

a phase detection circuit structured to determine a relative phase difference between at least one of the plurality of detection values and at least one of the at least one timing signal from the timer circuit; and

a response circuit structured to perform at least one operation in response to the relative phase difference, wherein the at least one operation comprises:

selecting at least one of the plurality of detection values, wherein the selecting is based on the relative phase difference;

using the selected at least one of the plurality of detection values for subsequent operations of the signal evaluation circuit to determine the relative phase difference; and

refraining from using at least one of the plurality of detection values that were not selected for subsequent operations of the signal evaluation circuit to determine the relative phase difference.

2. The system of claim 1 , wherein the response circuit is further structured to perform the at least one operation in response to a change in frequency or relative phase of at least one of the plurality of detection values.

3. The system of claim 2 , wherein the signal evaluation circuit is further structured to utilize a phase lock loop (PLL) to determine the change in the frequency or relative phase of the at least one of the plurality of detection values.

4. The system of claim 3 , wherein the signal evaluation circuit is further structured to utilize a band pass filter to determine the change in the frequency or relative phase of the at least one of the plurality of detection values.

5. The system of claim 4 , wherein the at least one operation comprises enabling or disabling processing of at least one of the plurality of detection values by the data acquisition circuit in response to the change in the frequency or relative phase of the at least one of the plurality of detection values.

6. The system of claim 4 , wherein the at least one operation comprises switching a utilized one of the plurality of input sensors in response to the change in the frequency or relative phase of the at least one of the plurality of detection values.

7. The system of claim 4 , wherein the at least one operation comprises providing an alert in response to the change in the frequency or relative phase of the at least one of the plurality of detection values.

8. The system of claim 1 , wherein the response circuit is further structured to perform the at least one operation in response to a transition event of at least one of the plurality of detection values.

9. The system of claim 1 , wherein the at least one operation comprises enabling or disabling processing of at least one of the plurality of detection values by the data acquisition circuit.

10. The system of claim 1 , wherein the at least one operation comprises switching a utilized one of the plurality of input sensors.

11. The system of claim 1 , wherein the at least one operation comprises providing an alert in response to the relative phase difference.

16. The system of claim 15 , wherein the response circuit is further structured to perform the at least one operation in response to a change in frequency or relative phase of at least one of the plurality of detection values.

17. The system of claim 16 , wherein the signal evaluation circuit is further structured to utilize a phase lock loop (PLL) to determine the change in the frequency or relative phase of the at least one of the plurality of detection values.

18. The system of claim 17 , wherein the signal evaluation circuit is further structured to utilize a band pass filter to determine the change in the frequency or relative phase of the at least one of the plurality of detection values.

19. A method for monitoring a fan, the method comprising:

interpreting a plurality of detection values, each of the plurality of detection values corresponding to at least one of a plurality of input sensors operationally coupled to the fan;

generating at least one timing signal;

determining a relative phase difference between at least one of the plurality of detection values and at least one of the at least one timing signal; and
