Signal processing method and device for compaction degree detection, storage medium and electronic device
The invention discloses a signal processing method and device for compactness detection, a storage medium and an electronic device. The signal processing method for compactness detection comprises the following steps: receiving an acceleration signal of a runner wheel during impact vibration, which is acquired by an acceleration sensor; carrying out time domain analysis on the collected acceleration signal; equally dividing the acceleration signal after the time domain analysis into N point sequences; judging whether the sequence number of the N-point sequence exceeds a preset sequence number threshold value or not; if yes, carrying out time-frequency domain conversion on the acceleration signal subjected to time domain analysis by adopting FFT (Fast Fourier Transform); if not, carrying out frequency domain conversion on the acceleration signal subjected to the time domain analysis by adopting discrete Fourier conversion; and outputting a conversion result to a display for displaying. The technical problems that the calculation amount is large, and the minimum calculation amount cannot be guaranteed are solved.
本申请公开了一种用于压实度检测的信号处理方法、装置、存储介质及电子装置。该用于压实度检测的信号处理方法包括：接收加速度传感器采集到的冲击振动时碾轮的加速度信号；对采集到的加速度信号进行时域分析；将时域分析后的加速度信号等分为N点序列；判断N点序列的序列数目是否超出预设的序列数目阈值；如果是，则采用FFT对时域分析后的加速度信号进行时频域转换；如果不是，则采用离散Fourier变换对时域分析后的加速度信号进行频域转换；输出转换结果到显示器上显示。本申请解决了运算量大，且无法保证最低运算量的技术问题。
