To detect that unaligned winding has occurred regardless of the number of layers of wire rope wound around a drum.SOLUTION: A winch drum random winding detection device 1 provided with an imaging device 10 that photographs a wire rope 3 wound around a drum 2 to generate image data, and a random winding determination unit 11. The random winding determination unit 11 is provided with an image analysis unit 13 including a trained model of a neural network that analyzes the image data generated by the image pickup device 10, and a determination unit 14 for determining whether in a normal winding state in which the wire rope 3 is wound in line with the drum 2, or in an unaligned winding state in which the wire rope 3 wound in an unaligned with the drum 2.SELECTED DRAWING: Figure 1

    【課題】ドラムに巻かれるワイヤーロープの層数によらずに、乱巻が発生したことを検出する。【解決手段】ウインチドラム乱巻検出装置1は、ドラム2に巻かれたワイヤーロープ3を撮影して画像データを生成する撮像装置10と、乱巻判定部11と、を備える。乱巻判定部11は、撮像装置10が生成した画像データを分析するニューラルネットワークの学習済モデルを含む画像分析部13と、ワイヤーロープ3がドラム2に整列して巻かれている正常巻状態であるか、ドラム2に巻かれたワイヤーロープ3が整列していない乱巻状態であるかを判定する判定部14と、を備える。【選択図】図1
