PROBLEM TO BE SOLVED: To provide an abnormality detection device for an elevator power failure lamp that enables proper discrimination of abnormal factors, when determining abnormality of the power failure lamp by a state confirmation of the power failure lamp by using a monitoring camera.SOLUTION: In the abnormality detection device for a power failure lamp, in a power failure state where the supply of a power source power 7a from a commercial power source 7 is interrupted, a power failure detection power source switching device 8 supplies a discharge power 9a from a battery 9 to a power failure lamp 2 and in addition, to a monitoring camera 4 and a monitoring camera device 5. The camera 4 transmits camera image capturing signals 103 indicating an imaging result including a lighting state of the power failure lamp 2 to the camera device 5. The camera device 5 records camera images that are results of image processing of the signal 103, and at a time of power supply restoration from a commercial power source 7, transmits camera image signals indicating camera images to a camera image record determination part 11, which has an image analysis function, provided in an elevator control device 10. The data determination part 11 performs an image analysis on the basis of the camera image signals, and determines the abnormalities of the battery 9, the power failure lamp 2, the camera 4, or the camera device 5 according to a type.SELECTED DRAWING: Figure 3

    【課題】監視カメラを利用した停電灯の状態確認で停電灯の異常判定時に異常要因を適確に判別できるエレベータ用停電灯異常検出装置を提供する。【解決手段】この停電灯異常検出装置では、商用電源7からの電源電力7aの供給が遮断された停電状態で停電検出電源切替え装置8がバッテリ9から停電灯2の他、監視カメラ4及び監視カメラ装置5へ放電電力9aの供給を行い、カメラ4が停電灯2の点灯状態を含めた撮影結果を示すカメラ撮影信号103をカメラ装置5へ伝送し、カメラ装置5では信号103を画像処理した結果のカメラ画像を記録し、商用電源7からの電源供給復帰時にカメラ画像を示すカメラ画像信号をエレベータ制御装置10に備えられた画像解析機能を持つカメラ画像記録データ判定部11へ伝送する。データ判定部11では、カメラ画像信号に基づいて画像解析を行ってバッテリ9、停電灯2、カメラ4又はカメラ装置5の異常を種別に判定する。【選択図】図3
