S204: and when the difference value between the spectrum peak value and the total sound decibel value is larger than or equal to a preset difference value, determining the abnormal spectrum data as the noise spectrum data.
It can be understood that the abnormal spectrum data can be determined as the noise spectrum data only when the difference between the spectrum peak value and the total decibel value of the sound is greater than or equal to a preset difference. Specifically, the preset difference value can be set according to requirements. In one embodiment, the predetermined difference is 10 dB. In one embodiment, the preset difference is 5 Db.
S206: and when the difference value between the spectrum peak value and the total sound decibel value is smaller than a preset difference value, determining that the abnormal spectrum data is the suspected noise spectrum data.

Specifically, the preset difference is set as described in the above embodiment.
In an embodiment, after the step of determining that the abnormal spectrum data is the suspected noise spectrum data when the difference between the spectrum peak value and the total decibel value of the sound is smaller than a preset difference, the step of determining that the audio spectrum data is the abnormal spectrum data further includes: and when the frequency of the suspected noise spectrum data in the preset time exceeds the preset frequency, determining the suspected noise spectrum data as the noise spectrum data.
It can be understood that, after the abnormal spectrum data is judged to be the suspected noise spectrum data, the suspected noise spectrum data can be determined to be the noise spectrum data only when the number of times of occurrence of the suspected noise spectrum data in a preset time exceeds a preset number of times. If the number of times of the suspected noise spectrum data appearing in the preset time does not exceed the preset number of times, the suspected noise spectrum data cannot be judged to be the noise spectrum data. It is to be understood that the setting of the preset time and the preset number is described in the above embodiments, and the description is not repeated here.
In one embodiment, before the step of obtaining, by the processor, code information corresponding to the audio spectrum data according to the audio spectrum data and sending the code information to the main control board, the method further includes: and if the noise parameter threshold does not exceed the preset noise parameter threshold, returning to the step of acquiring the sound information of the environment where the air conditioning unit is located through the acquisition device.

And returning to the step of acquiring the sound information of the environment where the air conditioning unit is located through the acquisition device, and waiting for the acquisition device to acquire the sound information of the environment where the air conditioning unit is located next time.
In one embodiment, step S30 further includes the steps of: matching the audio frequency spectrum data with preset noise spectrum data to obtain noise spectrum data matched with the audio frequency spectrum data; and acquiring code information corresponding to the noise spectrum data according to the noise spectrum data.
It can be understood that the audio frequency spectrum data is matched with preset noise spectrum data, and if the preset noise spectrum data has noise spectrum data consistent with the audio frequency spectrum data, code information corresponding to the noise spectrum data is directly acquired. And if the preset noise spectrum data does not have the noise spectrum data consistent with the audio frequency spectrum data, matching the noise spectrum data with high similarity to the audio frequency spectrum data. And code information corresponding to the noise spectrum data is acquired.

And setting the total decibel value of the sound to be more than 40dB, and setting the difference value between the peak value of the frequency spectrum and the total decibel value of the sound to be more than 10dB, so that the noise is considered to be normal noise. If the total decibel value of the sound exceeds 40dB or the difference between the peak value of the frequency spectrum and the total decibel value of the sound is greater than 10dB, the sound is considered to be abnormal noise (namely suspected noise).
Specifically, in one embodiment, after the collection device 100 collects a sound information, it converts the sound information into audio spectrum data. The peak value of the frequency point of 100Hz appears, the difference value between the peak value and the total decibel value of the sound is 5dB, and the frequency of the similar frequency spectrum continuously received within the preset time exceeds the preset frequency.

The information displayed by the terminal 400 is used for looking up a table (namely table one), the judgment result is correspondingly known to be the excitation sound of the magnetic field of the motor body, and the solution is further known to be whether the motor assembly is intact, whether the motor is loosened, whether a screw for fixing the motor is loosened and the like. If it is confirmed that there is no problem in the assembly, it is determined that the motor itself has a failure and the motor replacement process is required.
In one embodiment, the frequency value of the sharp peak in the audio frequency spectrum data of the sound information collected by the collecting device 100 is f-rpm/60 n (n-1, 2, 3, 4, 5 … …), such as f-1000 x 50/60 x 2 x 1666Hz, and the difference between the total value and the peak value is less than 10 dB. The problem of the beat frequency of the fan blade is judged after table lookup (namely table one), the corresponding processing scheme is that the return air inlet is blocked to see whether the noise disappears, if the air channel is not changed, the fan blade is judged to be changed, and the fan blade needs to be replaced for processing;
in one embodiment, when the collecting device 100 collects the audio frequency spectrum data of the sound information, the total decibel value of the sound is greater than 40dB, and the difference between the peak value and the total decibel value of the sound is also greater than 10 dB. After table look-up (namely table one), the problem of overlarge wind noise caused by improper type selection or improper static pressure selection is judged, the corresponding solution is to replace the motor capacitor, and if the motor capacitor is not satisfactory, the motor with a small size is replaced.
