To provide an elevator failure diagnosis system capable of reducing a failure restoration time by investigating a cause of the failure accurately even when a failure state is varied in accordance with an operation state of a car such as a load mounted on the car of the elevator and an operation direction of the car.SOLUTION: The elevator failure diagnosis system of the invention includes a failure state management unit for organizing and classifying failure states by failure modes such that failure logs are extracted from a failure daily report management unit of an elevator having complicated failure modes such as changes in failure states due to loads mounted on respective cars of the elevator and operation directions of cars and discriminating whether or not there is an operation situation of an elevator, which may cause an adverse effect, in each failure mode. When it is determined that a failure mode is associated with an operation situation of the elevator, an operation situation of the elevator corresponding to the failure mode is extracted from the operation information management unit storing operation situations by using the serial number of the failed elevator and the failure occurrence date of the elevator as keys so as to be combined with a failure log.SELECTED DRAWING: Figure 1
【課題】昇降機の乗りかごに積載される荷重及び乗りかごの運転方向の等の乗りかごの稼働状態に応じて故障状態が変化する場合でも正確に故障の原因を究明して故障復旧時間を短縮可能な昇降機の故障診断システムを提供する。【解決手段】本発明の昇降機故障診断システムは、昇降機の各乗りかごに積載される荷重及び乗りかごの運転方向によって故障状態が変化する等の複雑な故障モードを持つ昇降機の故障日報管理部から故障ログを引き出して故障状態を故障モード別に整理分類し、故障モード毎に影響を及ぼす昇降機の稼働状況の有無を判別するための故障状態管理部を備え、故障モードと昇降機の稼働状況の関連があると判断されたときに、稼働状況を格納する稼動情報管理部に故障した昇降機の製造番号、昇降機の故障発生日をキーに稼動情報管理部から故障モードに対応した昇降機の稼働状況を引き出し、故障ログと結合する構成とした。【選択図】図1
