Those skilled in the art can know that, with the evolution of the compressor noise reduction system and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0046] As shown in Figure 2 Figure 2 An embodiment flow schematic diagram of the compressor noise reduction method in the embodiments of the present application is shown, and the method specifically includes the following steps 201-203.

[0047] 201. Obtain current noise information of a target compressor working.

[0048] In the embodiments of the present application, the target compressor is used for space refrigeration, for example, refrigerating the food storage compartment of a refrigerator, or refrigerating a room by an air conditioner, and the specific embodiments of the present application do not limit it.

[0049] When the compressor works, it will produce noise due to compression refrigeration, which will affect the use of the user. In the embodiments of the present application, the sound collecting device, such as a microphone, a sound sensor, etc., including a microphone with a model of SP-01, a frequency range of 20Hz-20kHz, and a signal-to-noise ratio of 60dB, can be used. Specifically, the embodiments of the present application do not limit it. When the compressor works, the sound collecting device will obtain the sound signal generated by the compressor. In the embodiments of the present application, the sound collecting device can be installed at a suitable position to collect the sound signal generated by the compressor. For example, it is installed on the side of the compressor, and the specific embodiments of the present application do not limit it.

[0050] 202. Determine a target ultrasonic signal for canceling the noise of the target compressor according to the current noise information.

[0051] ​The noise information belongs to the sound information, and the essence of the sound is a vibration signal in the air. The vibration signal has the characteristics of a wave. If the size of the sound wave is to be reduced, when the wave crest of one sound wave is aligned with the wave trough of another sound wave, their amplitudes cancel each other out, forming a smaller wave or even completely disappearing. This situation is called destructive interference. For example, when the phase difference of two sound waves is 180 degrees, they will cancel each other out, that is, the weakening of the sound wave can be achieved, so the target ultrasonic signal for canceling the noise of the target compressor can be determined based on the frequency of the current noise information. Therefore, in the embodiment of the application, an ultrasonic wave with a multiple of the frequency of the current noise information can be used to interfere with the noise information. Since the ultrasonic wave cannot be heard by the human ear, the volume of the noise information can be reduced after the interference of the ultrasonic wave, thereby realizing the scheme of reducing the noise volume.

[0052] In some embodiments, according to the current working frequency and the current noise information, the step of determining the target ultrasonic signal for canceling the noise of the target compressor specifically comprises: generating the target ultrasonic signal for canceling the noise of the target compressor by the ultrasonic signal generator according to the current working frequency and the current noise information. Optionally, the ultrasonic signal generator can use an ultrasonic signal generator with a model of USG-01, a frequency range of 20 kHz-100 kHz, and an output power of 10 W.

[0053] 203、Control the ultrasonic wave emitter to emit the target ultrasonic signal to cancel the noise of the target compressor.

[0054] After the frequency of the specific target ultrasonic signal is determined, the target ultrasonic signal is directly emitted, which can cancel the noise generated by the compressor in the space to a certain extent. The ultrasonic wave emitter can use an ultrasonic wave emitter with a model of UE-01, a frequency range of 20 kHz-100 kHz, and a power of 10 WUSG.

[0055] The compressor noise reduction method provided in the application can first acquire the current noise information emitted by the compressor, and determine the target ultrasonic signal capable of canceling the noise according to the current noise information. Finally, the target ultrasonic signal is emitted by controlling the ultrasonic wave emitter, so as to eliminate or reduce the influence of the noise information generated by the compressor, and realize the noise reduction effect.

[0056] In order to better realize the embodiment of the application, in one embodiment of the application, according to the current noise information, the target ultrasonic signal for canceling the noise of the target compressor is determined, comprising:

[0057] Determine the current working frequency of the target compressor; and determine the target ultrasonic signal for canceling the noise of the target compressor according to the current working frequency and the current noise information.

[0058] The above embodiments provide a method for determining a target ultrasonic signal for canceling according to noise information generated by a compressor. In order to further increase the noise reduction effect, the embodiments of the present application also provide a scheme of combining the compressor frequency based on the current noise information.

[0059] Specifically, the noise generated by the compressor is caused by its own operation. The compressor itself has a working frequency, and the self-generated vibration of the compressor combines with the sound signal generated by the compressor, resulting in the superposition of the two vibration signals. Therefore, in the space, there may exist not only the noise signal generated by the compressor, but also the vibration sound vibration signal generated by the compressor. Therefore, in the embodiments of the present application, the current working frequency of the compressor can be determined by the device carrying the compressor according to the working frequency of the compressor.

[0060] Based on this, the compressor frequency can be determined by the device carrying the compressor, and the noise information obtained by the radio device is combined to determine two sound vibration waveforms, and then a composite ultrasonic signal is determined for the two vibration signals. As can be seen, by this way, the signal of the compressor vibration can be further canceled, thereby realizing the effect of improving the noise reduction effect.

[0061] In order to better realize the embodiments of the present application, in one embodiment of the present application, the target compressor is arranged on the target device, and the current working frequency of the target compressor is determined, comprising:

[0062] The current environment temperature, the target running period of the target device, the first running time of the target compressor, and the second running time of the target device are obtained; and the current working frequency of the target compressor is determined according to the current environment temperature, the target running period, the first running time, and the second running time.

[0063] The above embodiments provide a scheme for directly determining the current working frequency of the compressor according to the device carrying the compressor. The embodiments of the present application also provide a scheme for determining the working frequency of the compressor.

[0064] Specifically, the current working frequency of the compressor can be determined according to the current environment temperature, the target running period of the target device, the first running time of the target compressor, and the second running time of the target device.

[0065] The current environment temperature can be obtained by an environment temperature sensor, and the second running time of the target device can be determined by recording the time elapsed between the boot time of the target device and the current time by a timer in the target device.

[0066] After obtaining the current environment temperature, the target running period of the target device, the first running time of the target compressor and the second running time of the target device, the current working frequency of the compressor can be determined according to the related mapping relationship. The current environment temperature, the target running period, the first running time and the second running time are input parameters, and the current working frequency of the compressor can be obtained by the preset mapping relationship after inputting the four input parameters.

[0067] In order to better realize the embodiment of the application, in an embodiment of the application, the method of controlling the ultrasonic wave emitter to emit the target ultrasonic wave signal comprises:

[0068] determining a target working area of the target compressor; and controlling the ultrasonic wave emitter to emit the target ultrasonic wave signal to the target working area.

[0069] The above embodiment provides a way of emitting ultrasonic waves to an environment space. In order to improve the noise reduction effect, a positioner can be installed on the compressor in the embodiment of the application, the position of the compressor is determined by the positioner, and then the position of the compressor is determined as the target working area of the compressor.

[0070] At this time, the orientation of the ultrasonic wave emitter can be controlled to point to the position of the positioner by the positioning signal emitted by the positioner, so that the ultrasonic wave emitter can emit the target ultrasonic wave signal to the target working area.

[0071] In order to better realize the embodiment of the application, in an embodiment of the application, after controlling the ultrasonic wave emitter to emit the target ultrasonic wave signal, the method further comprises:

[0072] determining the noise-reduced environment sound frequency information; and controlling the working frequency of the target compressor according to the corresponding environment volume of the environment sound frequency information.

[0073] In order to further improve the noise reduction effect of the compressor, the sound frequency information in the environment can be obtained after the noise information is reduced by the ultrasonic wave. The sound sensor can be installed in the environment space to obtain the environment sound frequency information.

[0074] If the volume corresponding to the ambient sound frequency information is high, the working frequency of the compressor can be adjusted appropriately. For example, when the noise is reduced, the volume of the ambient noise is still high, and the working frequency of the compressor can be appropriately reduced to alleviate the volume of the ambient noise.

[0075] To better implement the embodiments of the present application, in an embodiment of the present application, the working frequency of the target compressor is controlled according to the ambient volume corresponding to the ambient sound frequency information, comprising:

[0076] If the ambient volume is greater than or equal to the target decibel value, the working frequency of the target compressor is reduced; if the ambient volume is less than the target decibel value and the target refrigeration space has not reached the target refrigeration temperature, the working frequency of the target compressor is increased.

[0077] In the embodiments of the present application, an implementation is also provided. Specifically, when the ambient volume has not reached the target decibel value and the temperature in the current room or food storage chamber has not reached the target refrigeration temperature. At this time, it can be regarded that the refrigeration effect of the compressor is poor, but at the same time the volume in the environment is still low. Therefore, the working frequency of the compressor can be appropriately increased until the ambient volume is equal to the target decibel value, and then the increase of the working frequency of the compressor is stopped. In this way, the refrigeration effect can be maximized, and the noise reduction demand can also be met.

[0078] To better implement the embodiments of the present application, in an embodiment of the present application, after the target ultrasonic signal emitted by the ultrasonic emitter is controlled, the method further comprises:

[0079] Determine whether the ambient volume corresponding to the ambient sound frequency information after noise reduction is greater than or equal to the target decibel value; if the ambient volume is greater than or equal to the target decibel value, adjust the signal parameter corresponding to the target ultrasonic signal and / or adjust the emitter parameter of the ultrasonic emitter to reduce the ambient volume.

[0080] The above embodiments provide a scheme that if the ambient volume is still large after noise reduction, the ambient volume can be reduced by adjusting the frequency of the compressor, but this may affect the refrigeration effect. Therefore, an implementation of the embodiments of the present application is also provided.

[0081] Specifically, the target ultrasonic signal not only includes frequency information, but also includes phase information. Therefore, if the noise reduction effect is not ideal, the signal parameter related to the phase in the target ultrasonic signal can be adjusted to realize the translation of the target ultrasonic signal. The specific reason is that adjusting the phase can make the wave crest of the ultrasonic signal opposite to the wave trough of the noise information and the wave trough of the ultrasonic signal opposite to the wave crest of the noise information, so that the volume of the noise is maximized by the wave crest canceling the wave trough.

[0082] In addition, in the embodiment of the present application, the ultrasonic wave emitter can also be installed in multiple numbers, if the noise reduction effect is not ideal. The multiple ultrasonic wave emitters can be started to emit ultrasonic waves at the same time, so as to increase the noise reduction effect. Therefore, the emitter parameter can include the number of emitters. Alternatively, the emitter parameter can include the orientation angle of the emitter. By randomly rotating the emission orientation of the emitter, the current ambient volume is collected every time the orientation of the emitter changes, so as to find the orientation of the minimum ambient volume. The specific embodiment of the present application is not limited thereto.
