To provide an operation monitoring device and an operation monitoring method that are able to monitor an operating state of a crane apparatus with higher accuracy.SOLUTION: An operation monitoring device comprises: a first acceleration sensor mounted near a drive source that drives a crane apparatus; an acquisition unit that acquires a detection signal from each of second acceleration sensors mounted in a position further apart than the first acceleration sensor from the drive source; a generation unit that generates a differential signal obtained by subtracting a detection signal from each of the second acceleration sensors from a detection signal from the first acceleration sensor; and a determination unit that, based on the differential signal, determines an operating state of the crane apparatus or the drive source.SELECTED DRAWING: Figure 4
【課題】クレーン装置の稼働状態をより高精度に監視することができる稼働監視装置及び稼働監視方法を提供する。【解決手段】クレーン装置を駆動する駆動源の近傍に取り付けられる第1の加速度センサと、前記駆動源に対し前記第1の加速度センサよりも離れた位置に取り付けられる第2の加速度センサとの各々から検出信号を取得する取得部と、前記第1の加速度センサの検出信号から前記第2の加速度センサの検出信号を差し引いた差信号を生成する生成部と、前記差信号に基づいて前記クレーン装置又は前記駆動源の稼働状態を判定する判定部と、を備える。【選択図】図4
