    • A working process monitoring device includes: a sensor unit for detecting at least one of vibrations and sound waves produced while processing a workpiece by a working machine rotatably driven by a driving unit; a signal input unit for extracting target signals from an electric signal outputted from the sensor unit; and an amount of characteristics extracting unit for extracting amounts of characteristics including a plurality of parameters from the target signals. Further, the working process monitoring device includes a material inspecting unit for detecting whether a material of a portion of the workpiece currently being processed is normal in quality or not, wherein the material inspecting unit employs a neural network trained by using amounts of characteristics extracted from target signals obtained while processing a workpiece made of a normal quality material.
    • 工作过程监控装置包括:传感器单元,用于检测通过由驱动单元可旋转地驱动的工作机器处理工件时产生的振动和声波中的至少一个; 信号输入单元,用于从传感器单元输出的电信号中提取目标信号; 以及一定量的特征提取单元,用于从目标信号中提取包括多个参数的特征量。 此外,工作过程监视装置包括用于检测当前正在处理的工件的一部分材料的质量是否正常的材料检查单元,其中材料检查单元采用通过使用从 在处理由正常质量材料制成的工件时获得的目标信号。
