Anomaly Sensing and Diagnosis Method, Anomaly Sensing and Diagnosis System, Anomaly Sensing and Diagnosis Program and Enterprise Asset Management and Infrastructure Asset Management System
In order to provide a facility of a plant or the like with an anomaly detection/diagnosis method and an anomaly detection/diagnosis system which are capable of detecting an anomaly of the facility with a high degree of sensitivity at an early time, pieces of maintenance-history information composed of past examples such as a work history and information on replaced parts are associated in advance with each other by the appearance frequency (context) of a keyword and, on the basis of anomaly detection making use of signals output by a multi-dimensional sensor installed in the facility as an object, the detected anomaly is linked to the pieces of maintenance-history information which are associated with each other. Thus, at a point of time prediction is detected, it is possible to give a relationship with a countermeasure such as a replacement of a part, an adjustment or a restart.
