Steel wire rope flaw detection device

In a wire rope flaw detection device, a magnetizer generates a part of magnetic flux passing through a wire rope. The magnetic sensor generates, as a sensor signal, a signal corresponding to a leakage magnetic flux that leaks from the wire rope among the magnetic fluxes. The filter unit extracts a frequency component of the sensor signal. The calculation unit extracts a plurality of feature quantities based on a plurality of values constituting the frequency component. The learning unit determines the presence or absence of damage to the wire material included in the wire rope by performing arithmetic processing on a learning model when the plurality of feature quantities are input to a learned learning model in which machine learning is performed on the correlation between the plurality of feature quantities and the state of the wire material included in the wire rope. 在钢丝绳探伤装置中，磁化器发生经过钢丝绳的一部分的磁通。磁传感器发生与磁通之中的从钢丝绳泄漏的泄漏磁通对应的信号作为传感器信号。滤波器部抽出传感器信号的频率分量。运算部抽出基于构成频率分量的多个值的多个特征量。学习部通过使向关于多个特征量和包含于钢丝绳的线材的状态的相关关系进行了机
