DIAGNOSTIC SYSTEM, DIAGNOSTIC METHOD AND DIAGNOSTIC PROGRAM

PROBLEM TO BE SOLVED: To provide a diagnostic system, a diagnostic method and a diagnostic program capable of high accuracy diagnosis to which a diagnostic model common to a plurality of pieces of equipment assumed to be close in operation condition is applied.SOLUTION: An equipment-information calculation unit 12 obtains linked equipment information by linking fixed first linked equipment information and variable second linked equipment information, which are associated with monitoring items including basic equipment information about to-be-monitored equipment, to the basic equipment information. The equipment-information classification unit classifies the linked equipment information. An equipment-state diagnostic unit 13 obtains a feature quantity of an analysis result of analysis of measurement data corresponding to the monitoring items. The equipment-state diagnostic unit diagnoses a state of the to-be-monitored equipment using a diagnostic pattern of the feature quantity of the analysis result corresponding to a classification result of the equipment-information classification unit. The equipment-information classification unit obtains a feature quantity of the linked equipment information. The equipment-information classification unit classifies the linked equipment information to any of a plurality of equipment feature patterns stored in advance on the basis of the feature quantity of the linked equipment information.SELECTED DRAWING: Figure 1 【課題】運転条件が近いとみなされる複数の機器に共通の診断用モデルを適用した高精度の診断が可能な診断システム、診断方法及び診断プログラムを提供する。【解決手段】機器情報分類部１２は、監視対象機器の基本機器情報を含む監視項目に関連し固定された第１被結合機器情報と可変の第２被結合機器情報を基本機器情報に結合した結合機器情報を得る。機器情報分類部は結合機器情報を分類する。機器状態診断部１３は、監視項目に対応する測定データを解析した解析結果の特徴量を得る。機器状態診断部は、監視対象機器の状態を機器情報分類部の分類結果に対応した解析結果の特徴量の診断パターンを用いて診断する。機器情報分類部は結合機器情報の特徴量を得る。機器情報分類部は、結合機器情報の特徴量に基づいて結合機器情報を予め記憶された複数の機器特徴パターンのいずれかに分類する。【選択図】図１
