摘　　要：为实现针对造纸机烘缸固有频率的实时检测,确保干燥部稳定运行,提出了一套基于传感器元件的固有频率检测系统,详细介绍了该系统的元件选型与电路设计方案,并通过快速傅里叶变换算法对来自传感器的时域信号加以转换,进而通过上位机输出相应的频域信号,最后以时域测量界面为例展示了该系统的可视化设计效果。In order to realize the real-time detection of the natural frequency of the drying cylinder of the paper machine and ensure the stable operation of the drying part, this study proposes a set of natural frequency detection system based on sensor elements. The component selection and circuit design scheme of the system are introduced in detail, converts the time-domain signal from the sensor through the fast Fourier transform algorithm, and then outputs the corresponding frequency-domain signal through the host computer. Finally, taking the time domain measurement interface as an example, the visual design effect of the system is shown.
