Intelligent Monitoring System and Method for Building Predictive Models and Detecting Anomalies
First Claim
1. A method for detecting an anomaly in data originating from a component used in an industrial process, the method comprising:
- providing predictive models in which at least one of the predictive models corresponds to at least one operating mode from a plurality of operating modes of the component;
obtaining operating data from the component, the operating data being indicative of a given operating mode from the operating modes;
selecting at least one of the predictive models based on the given operating mode;
generating estimated data using the selected at least one predictive model;
comparing the operating data with the estimated data; and
generating an alarm trigger when the comparison meets a given anomaly criteria thereby constituting the detection of the anomaly.

Abstract
There is described a method and system for detecting an anomaly in data originating from a component used in an industrial process. The anomaly detection steps comprise: providing predictive models in which at least one of the predictive models corresponds to at least one operating mode from a plurality of operating modes of the component; obtaining operating data from the component, the operating data being indicative of a given operating mode from the operating modes; selecting at least one of the predictive models based on the given operating mode; generating estimated data using the selected at least one predictive model; comparing the operating data with the estimated data; and generating an alarm trigger when the comparison meets a given anomaly criteria thereby constituting the detection of the anomaly.

15. A system for detecting an anomaly in data originating from a component used in an industrial process, the system comprising:
-
a predictive model builder for providing predictive models in which at least one of the predictive models corresponds to at least one operating mode from a plurality of operating modes of the component;
an input for receiving operating data from the component, the operating data being indicative of a given operating mode from the operating modes;
a calculation engine for selecting at least one of the predictive models based on the given operating mode;
the calculation engine further for generating estimated data using the selected at least one predictive model; and
an anomaly recognition engine for comparing the operating data with the estimated data and for generating an alarm trigger when the comparison meets a given anomaly criteria thereby constituting the detection of the anomaly. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
