System and method of monitoring by analyzing IoT data

摘要

The present invention relates to IoT data analysis. A monitoring method through IoT data analysis includes the steps of generating an N-dimensional normal data set having N features acquired during a steady state, and using the N-dimensional normal data set, one N-dimensional normal data distribution and N (N -1) generating a dimensional normal data distribution, generating N-dimensional monitoring data having N features obtained after the steady state, and using the N-dimensional normal data distribution, the N-dimensional monitoring data is an outlier determining whether it is, and detecting the feature causing the outlier from the N-dimensional monitoring data using the distribution of the N (N-1)-dimensional normal data.
