Abstract

Embodiments for implementing intelligent refrigeration compressor runtime schedule extraction in an Internet of Things (IoT) computing environment by a processor. Compressor runtime positions of a compressor may be determined according to a single phase signal taken from an energy meter. Performance and health status of the compressor may be established according to the one or more compressor runtime activities determined from the established nominal baseload classifier.

Claims (34)

1. A method for implementing intelligent refrigeration compressor runtime schedule extraction in an Internet of Things (IoT) computing environment by a processor, comprising:

determining one or more compressor runtime positions of a compressor according to a single phase signal collected from one phase of a three-phase power supply meter, wherein the single phase signal is an auxiliary energy signal generated by determining a mean value of an instantaneous phase current sampled from the one phase at predetermined time intervals for a defined time period; and

establishing performance and health status of the compressor according to the one or more compressor runtime positions.

2. The method of claim 1 , further including defining the single phase signal as a proxy for a compressor event detection operation.

3. The method of claim 1 , further including:

inferring a clustering of compression events using a machine learning operation coupled with one or more numerical algorithms; and

determining a compressor load classifier for a selected refrigeration pack.

4. The method of claim 3 , further including applying the compressor load classifier on the single phase signal to infer and build the one or more compressor runtime positions for the selected refrigeration pack.

5. The method of claim 3 , further including detecting anomalous behavior of the compressor using the compressor load classifier.

6. The method of claim 1 , further including automatically issuing a notification indicating anomalous behavior of the compressor.

7. The method of claim 1 , further including predicting operational failure of the compressor using a machine learning operation.

8. A system for implementing intelligent refrigeration compressor runtime schedule extraction in an Internet of Things (IoT) computing environment, comprising:

one or more computers with executable instructions that when executed cause the system to:

determine one or more compressor runtime positions of a compressor according to a single phase signal collected from one phase of a three-phase power supply meter, wherein the single phase signal is an auxiliary energy signal generated by determining a mean value of an instantaneous phase current sampled from the one phase at predetermined time intervals for a defined time period; and

establish performance and health status of the compressor according to the one or more compressor runtime positions.

9. The system of claim 8 , wherein the executable instructions further define the single phase signal as a proxy for a compressor event detection operation.

10. The system of claim 8 , wherein the executable instructions further:

infer from the clustering of compression events using a machine learning operation coupled with one or more numerical algorithms; and

determine a compressor load classifier for a selected refrigeration pack.

11. The system of claim 10 , wherein the executable instructions further apply the compressor load classifier on the single phase signal to infer and build the one or more compressor runtime positions for the selected refrigeration pack.

12. The system of claim 10 , wherein the executable instructions further detect anomalous behavior of the compressor using the compressor load classifier.

13. The system of claim 8 , wherein the executable instructions further automatically issue a notification indicating anomalous behavior of the compressor.

14. The system of claim 8 , wherein the executable instructions further predict operational failure of the compressor using a machine learning operation.

15. A computer program product for implementing intelligent refrigeration compressor runtime schedule extraction in an Internet of Things (IoT) computing environment by a processor, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

an executable portion that determines one or more compressor runtime positions of a compressor according to a single phase signal collected from one phase of a three-phase power supply meter, wherein the single phase signal is an auxiliary energy signal generated by determining a mean value of an instantaneous phase current sampled from the one phase at predetermined time intervals for a defined time period; and

an executable portion that establishes performance and health status of the compressor according to the one or more compressor runtime positions.

16. The computer program product of claim 15 , further including an executable portion that defines the single phase signal as a proxy for a compressor event detection operation.

17. The computer program product of claim 15 , further including an executable portion that:

infers a clustering of compression events using a machine learning operation coupled with one or more numerical algorithms;

determines a compressor load classifier for a selected refrigeration pack; and

applies the compressor load classifier on the single phase signal to build the one or more compressor runtime positions for the selected refrigeration pack.

18. The computer program product of claim 17 , further including an executable portion that detects anomalous behavior of the compressor using the compressor load classifier.

19. The computer program product of claim 15 , further including an executable portion that automatically issues a notification indicating anomalous behavior of the compressor.

20. The computer program product of claim 15 , further including an executable portion that predicts operational failure of the compressor using a machine learning operation.
