the specific mode of the controller for processing the audio data collected by the audio collecting microphone is as follows:
the controller firstly divides the audio data into audio segments with the length of 1-5 s;
then, transforming the segmented audio segments to obtain audio frequency spectrums of a frequency domain;
carrying out frequency band segmentation on the obtained audio frequency spectrum, and deducting the working frequency of the working electric signal in the line and the frequency of 2-4 times of the working frequency of the working electric signal so as to deduct the influence of excitation noise; further deducing the frequency corresponding to the rotating speed of the fan and the resonance frequency range of the fan from the audio frequency spectrum, thereby removing the influence of the rotation of the fan;
performing audio energy calculation on the processed audio frequency spectrum to obtain energy A of the audio segment 0 (ii) a The characteristic frequency range of the line friction noise is stored in the controller in advance, and the intensity of the processed audio frequency spectrum in the characteristic frequency range of the line friction noise is calculated to obtain the line friction noiseEnergy A 1 ；
The method for calculating the rotating speed of the fan by the processor comprises the following steps: the rotating speed of the fan is as follows:
R=k 1 ·P+k 2 ·EXP(k 3 ·A 1 )-k 4 ·EXP[k 5 ·(A 0 -A 1 )]；
wherein k is 1 、k 2 、k 3 、k 4 、k 5 Are empirical coefficients.
