Classification: CPC G | IPC G

Claim 6:
7. A method for monitoring power distribution equipment, comprising:
generating respective sensor signals indicative of sounds and/or vibrations originating from a respective space system equipment of a plurality of space system equipment arranged at various different locations, the respective sensor signals being detected by a plurality of sensing assemblies located on, in or proximate the plurality of space system equipment;
processing the respective sensor signals to detect anomalies from operation of the respective space system equipment using a processor of an intelligent audio analytic (IAA) device, the processor being configured to process the respective sensor signals according to an analytics algorithm to detect the anomalies, the analytics algorithm including an autoencoder neural network configured to detect errors and/or patterns in the respective sensor signals indicative of the anomalies; and
outputting detection information to an output device when an anomaly is detected,
wherein the autoencoder network is configured to receive the respective sensor signals as input and to output respective reconstructed sensor signals based on the input,
wherein the processor is configured to (i) generate respective reconstruction error signals that are indicative of a difference between the input and the output of the autoencoder neural network for the respective sensor signals, (ii) detect anomalies based on a magnitude of each respective reconstruction error signal, and (iii) perform spatio-temporal analysis of load distribution impacts on the plurality of space system equipment by aggregating results from the plurality of space system equipment arranged at the various different locations.
