System and method for detecting and predicting anomalies based on analysis of time-series data
First Claim
1. An abnormality detecting and predicting system, comprising:
- a database configured to store past case data related to a state of a monitored object;
a data collector configured to collect status information from the monitored object;
an abnormality detector configured to compare the status information, in a preset detecting interval, with an abnormality detecting reference, and to detect an occurrence of an abnormality of the monitored object;
a similar case selector configured to select a first case having a highest degree of similarity to the status information among the past case data when the occurrence of the abnormality is detected by the abnormality detector;
a predictor configured to predict proliferation or diminishing of the detected abnormality after the occurrence of the detected abnormality, by using the first case and an abnormality proliferation predicting reference; and
an abnormality detecting reference updater configured to adjust a length of the preset detecting interval based on a prediction result of the predictor and a change of the status information in a preset verification interval,wherein the abnormality detector is further configured to transmit a warning message to an administrator in response to the occurrence of the abnormality of the monitored object,wherein the past case data includes the monitored object'"'"'s pattern of changing status information over time when a past abnormality is detected and information of the detected past abnormality either proliferating or diminishing in a corresponding case,wherein the preset verification interval corresponds to one of a first interval starting from a time of the occurrence of the abnormality in the preset detecting interval and ending at an additional preset time interval after an ending of the preset detecting interval, and a second interval which starts from the ending of the preset detecting interval and ending after the additional preset time interval, andwherein the data collector, the abnormality detector, the similar case selector, and the predictor are executed by at least one central processing unit (CPU) or at least one hardware processor.

Abstract
Provided are a system and method for detecting and predicting anomalies based on analysis of time-series data. According to an embodiment of the present disclosure, an abnormality detecting and predicting system includes a database configured to store past case data related to a state of a monitored object; a data collector configured to collect time-series status information of the monitored object; an abnormality detector configured to compare the status information with an abnormality detecting reference in a preset detecting interval and detect an occurrence of an abnormality of the monitored object; a similar case selector configured to select a similar case having a highest degree of similarity to the status information among the past case data when the occurrence of an abnormality is detected by the abnormality detector; and a predictor configured to predict proliferation or diminishing of a detected abnormality using the similar case and an abnormality proliferation predicting reference.
