US 2014/0195184 A1 · Anomaly Detection/Diagnostic Method and Anomaly Detection/Diagnostic System

Abstract

Provided are an anomaly detection/diagnostic method and an anomaly detection/diagnostic system whereby it is possible, in equipment such as a plant, to detect anomalies promptly and with high sensitivity, wherein anomaly detection is carried out using operating information such as the operating time of the equipment and output signals from a plurality of sensors appended to the equipment, and wherein maintenance logs such as written procedure reports comprising procedure logs and instances of past countermeasures such as replacement part information are targeted to make associations between detected anomalies and countermeasures, and create links between anomaly detection and past maintenance logs, making reference to equipment records as well, while classifying and presenting anomalies that require action, thereby improving diagnostic accuracy.

An anomaly detection/diagnostic method used for detecting an anomaly of a plant or equipment or detecting an anomaly sign of said plant or said equipment and used for diagnosing said plant or said equipment, said anomaly detection/diagnostic method comprising:

detecting an anomaly of said plant or said equipment or detecting an anomaly sign of said plant or said equipment by taking sensor data acquired from a plurality of sensors installed in said plant or said equipment and/or operating data such as operation times and operating times as an object;
associating said anomaly of said plant or said equipment or said anomaly sign of said plant or said equipment with past countermeasures by making use of maintenance-history information of said plant or said equipment;
and
classifying and presenting said anomaly requiring a countermeasure or said anomaly sign requiring a countermeasure on the basis of results of said association.

An anomaly detection/diagnostic system used for detecting an anomaly of a plant or equipment or detecting an anomaly sign of said plant or said equipment and used for diagnosing said plant or said equipment, said anomaly detection/diagnostic system comprising:

an anomaly detection section for detecting an anomaly of said plant or said equipment or an anomaly sign of said plant or said equipment by taking sensor data acquired from a plurality of sensors installed in said plant or said equipment and/or operating data such as operation times and operating times as an object;
a database section for storing maintenance-history information comprising information such as countermeasures for said plant or said equipment;
and
a diagnostic section for associating an anomaly detected by said anomaly detection section as an anomaly of said plant or said equipment or an anomaly sign detected by said anomaly detection section as an anomaly sign of said plant or said equipment with past countermeasures by making use of information stored in said database section to serve as maintenance-history information of said plant or said equipment and for classifying and presenting an anomaly requiring a countermeasure or an anomaly sign requiring a countermeasure on the basis of results of said association.
