[0004] 2. Data acquisition: Use a data acquisition system or vibration monitoring equipment to record the vibration data measured by the sensor. These data include vibration acceleration, displacement, velocity and other information, which can be vibration signals in the time domain or frequency domain.

[0005] 3. Data analysis: Analyze and process the collected vibration data. Signal processing techniques such as Fourier transform, power spectrum density analysis, autocorrelation function, etc. can be used to extract the frequency components, periodicity, amplitude and other information of the vibration signal.
