[0035] Step S103: When the air conditioner has a noise problem, the electronic device obtains the source of the noise according to the frequency information of the sound information.

[0036] By adopting the method for obtaining the source of noise provided by the embodiment of the present disclosure, it is determined whether the air conditioner has a noise problem based on the sound information generated during the operation of the air conditioner. If the air conditioner has a noise problem, the source of the noise is obtained through the frequency information of the sound information. Since the noise frequency will change according to the source of the noise, the source of the noise can be determined through the frequency information of the sound information. This makes it convenient for users to adopt corresponding processing strategies according to the source of the noise, thereby reducing the noise.

[0037] Optionally, determining whether the air conditioner has a noise problem according to the sound information includes: determining that the air conditioner has a noise problem when there is frequency information exceeding a preset threshold in the sound information; and / or determining that the air conditioner does not have a noise problem when there is no frequency information exceeding a preset threshold in the sound information.

[0038] Optionally, obtaining the noise source according to the frequency information of the sound information includes: when the abnormal frequency is within a first preset interval, determining that the noise source is the compressor. The abnormal frequency is frequency information greater than a preset threshold; the first preset interval is the frequency operation interval of the compressor. In this way, by comparing the abnormal frequency with the frequency operation interval of the compressor, it is possible to determine whether the compressor is the source of the noise.

[0039] Optionally, obtaining the noise source according to the frequency information of the sound information includes: when the abnormal frequency is within a second preset interval, determining that the noise source is the compressor. The abnormal frequency is frequency information greater than a preset threshold. The second preset interval is a multiple of the frequency operating interval of the compressor. In this way, by comparing the abnormal frequency with the multiple of the frequency operating interval of the compressor, it is possible to determine whether the compressor is the source of the noise.

[0040] Optionally, after obtaining the noise source according to the frequency information of the sound information, the method further includes: inputting the sound information into a preset noise type recognition model to obtain the noise type.

[0046] By adopting the method for obtaining the source of noise provided by the embodiment of the present disclosure, it is determined whether the air conditioner has a noise problem based on the sound information generated during the operation of the air conditioner. If the air conditioner has a noise problem, the source of the noise is obtained through the frequency information of the sound information. Since the noise frequency will change according to the source of the noise, the source of the noise can be determined through the frequency information of the sound information. This makes it convenient for users to adopt corresponding processing strategies according to the source of the noise, thereby reducing the noise.

[0047] Furthermore, the noise type recognition model is obtained by the following method: sample sound information of multiple air conditioners in operation is obtained, each sample sound information has a sample label, and the sample label is the noise type.

[0049] In some embodiments, the sample sound information is a sharp "woosh" whistling sound, and the frequency of the sample sound information is between 2000 Hz and 5000 Hz, and the sample label is welding blockage of the compressor exhaust port.

[0050] In some embodiments, the sample sound information is a continuous "buzzing" sound with varying amplitudes, and the frequency of the sample sound information is between 100 Hz and 300 Hz, and the sample label is resonance between the reservoir and the pipeline, and large vibration of the reservoir.

[0051] In some embodiments, the sample sound information is a continuous and low "buzzing" sound. The frequency of the sample sound information is between 50 Hz and 400 Hz, and its sample labels are large vibration of the reservoir, resonance between the reservoir and the pipeline, large exhaust pulsation of the compressor, heavy load of the air conditioning system environment, and worsening vibration of the compressor.

[0052] In some embodiments, the sample sound information is a "gurgling" sound similar to the sound of boiling water. The frequency of the sample sound information is between 500 Hz and 630 Hz, and the sample label is that when the compressor is exhausting at a low speed, the inertial force and gas force of the exhaust valve plate cannot quickly reach a balance, causing the exhaust valve plate to vibrate and generate valve plate sound.

[0053] In some embodiments, the sample sound information is a "thump" sound. The frequency of the sample sound information is between 400 Hz and 800 Hz, and the sample label is that the thrust flat machining accuracy is poor and the crankshaft thrust surface is worn. The pressure pulsation phases on the upper and lower sides of the rotor differ by 180 degrees, and the amplitude is large, causing the crankshaft axial runout.

[0054] In some embodiments, the sample sound information is a "thump" sound. The frequency of the sample sound information is between 400 Hz and 800 Hz, and the sample label is that the thrust flat machining accuracy is poor and the crankshaft thrust surface is worn. The pressure pulsation phases on the upper and lower sides of the rotor differ by 180 degrees, and the amplitude is large, causing the crankshaft axial runout.

[0056] Combination Figure 3 As shown, the embodiment of the present disclosure provides a method for obtaining a noise source, comprising:

[0057] Step S301: The electronic device obtains sound information of the air conditioner in operation.

[0058] Step S302: The electronic device determines whether the air conditioner has a noise problem based on the frequency information of the sound information.

[0059] Step S303: When the air conditioner has a noise problem, the electronic device obtains the source of the noise according to the frequency information of the sound information.

[0060] Step S304: the electronic device inputs the sound information into a preset noise type recognition model to obtain the noise type.

[0061] Step S305: The electronic device determines a noise elimination strategy corresponding to the noise type, and sends the noise elimination strategy to a preset user terminal.

[0062] By adopting the method for obtaining the source of noise provided by the embodiment of the present disclosure, it is determined whether the air conditioner has a noise problem based on the sound information generated during the operation of the air conditioner. If the air conditioner has a noise problem, the source of the noise is obtained through the frequency information of the sound information. Since the noise frequency will change according to the source of the noise, the source of the noise can be determined through the frequency information of the sound information. This makes it convenient for users to adopt corresponding processing strategies according to the source of the noise, thereby reducing the noise.

[0063] Further, determining the noise elimination strategy corresponding to the noise type includes: performing a matching operation in a preset data table according to the noise type to obtain the noise elimination strategy corresponding to the noise type.

[0064] As shown in Table 1, the noise types include foreign matter inside the compressor; welding blockage at the compressor exhaust port; resonance between the accumulator and the pipeline; large vibration of the accumulator; large exhaust pulsation of the compressor; heavy load of the air conditioning system environment; deterioration of compressor vibration; the inertial force and gas force of the exhaust valve plate cannot quickly reach a balance when the compressor exhausts at a low speed, causing the exhaust valve plate to vibrate and produce valve plate sound; poor machining accuracy of the thrust plane and wear of the crankshaft thrust surface; the pressure pulsation phase difference of the upper and lower sides of the rotor is 180 degrees, and the amplitude is large, causing the crankshaft axial runout. The noise elimination strategy corresponding to the presence of foreign matter inside the compressor is to remove the foreign matter inside the compressor. The noise elimination strategy corresponding to the welding blockage of the compressor exhaust port is to eliminate the blockage of the exhaust port. The noise elimination strategy corresponding to the resonance of the accumulator and the pipeline is to increase or reduce the operating frequency of the compressor. The noise elimination strategy corresponding to the large vibration of the accumulator is to reduce the operating frequency of the compressor. The noise elimination strategy corresponding to the large exhaust pulsation of the compressor is to reduce the opening of the exhaust valve. The noise elimination strategy corresponding to the heavy load of the air conditioning system environment is to reduce the load of the air conditioning system. The noise elimination strategy corresponding to the deterioration of compressor vibration is to replace the compressor. When the compressor exhausts at low speed, the inertial force and gas force of the exhaust valve plate cannot quickly reach a balance, causing the exhaust valve plate to vibrate. The corresponding noise elimination strategy is to replace the compressor. The thrust plane machining accuracy is poor, and the crankshaft thrust surface is worn. The corresponding noise elimination strategy is to replace the compressor. The pressure pulsation phase on the upper and lower sides of the rotor differs by 180 degrees, and the amplitude is large, causing the crankshaft axial runout. The corresponding noise elimination strategy is to replace the compressor.
