[0045] It should be noted that Figure 1The scenario diagram of the compressor noise reduction system shown is only an example. The compressor noise reduction system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the compressor noise reduction system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0046] like Figure 2 As shown, Figure 2 This is a flow chart of an embodiment of a compressor noise reduction method in an embodiment of the present application. The method specifically includes the following steps 201 to 203:

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

[0048] In the embodiments of the present application, the target compressor is used for space cooling, such as cooling the food storage compartment of a refrigerator, or cooling a room with an air conditioner, etc., and the specific embodiments of the present application are not limited thereto.

[0049] When the compressor is working, it will generate noise due to compression and refrigeration, which will affect the user's use. In the embodiment of the present application, a sound receiving device, such as a microphone, a sound sensor, etc., can be used, including a microphone of model SP-01, with a frequency range of 20Hz to 20kHz and a signal-to-noise ratio of 60dB. Specifically, the embodiment of the present application is not limited to it. When the compressor is working, the sound receiving device will obtain the sound signal generated by the compressor. In the embodiment of the present application, the sound receiving device can be installed in a suitable position to collect the sound signal generated by the compressor. For example, it is installed on the peripheral side of the compressor. Specifically, the embodiment of the present application is also not limited to it.

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

[0051] Noise information belongs to sound information, and the essence of sound is a vibration signal in the air, and the vibration signal has the characteristics of a wave. If you want to reduce the size of the sound wave, when the crest of one sound wave is aligned with the trough of another sound wave, their amplitudes cancel each other out, forming smaller waves or even disappearing completely. This situation is called destructive interference. For example, when the phase difference between 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 used to offset the noise of the target compressor can be determined based on the frequency of the current noise information. Therefore, in an embodiment of the present application, an ultrasonic wave that is a multiple of the current noise information frequency can be used to achieve the interference of ultrasonic waves on noise information. Ultrasonic waves cannot be heard by the human ear, so after the interference of ultrasonic waves, the volume of the noise information can be reduced, thereby achieving a solution to reduce the noise volume.

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

[0053] 203. Control the ultrasonic transmitter to transmit a target ultrasonic signal to offset the noise of the target compressor.

[0054] After determining the frequency of the specific target ultrasonic signal, the target ultrasonic signal can be directly emitted to offset the noise generated by the compressor in the space to a certain extent. The ultrasonic transmitter can be a UE-01 ultrasonic transmitter with a frequency range of 20kHz to 100kHz and a power of 10WUSG.

[0055] The compressor noise reduction method provided by the present application can first obtain the current noise information emitted by the compressor, and determine the target ultrasonic signal that can offset the noise based on the current noise information. Finally, by controlling the ultrasonic transmitter to emit the target ultrasonic signal, the influence of the noise information generated by the compressor is eliminated or reduced, thereby achieving the noise reduction effect.

[0056] In order to better implement the embodiment of the present application, in one embodiment of the present application, determining a target ultrasonic signal for offsetting the noise of a target compressor according to current noise information includes:

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

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

[0059] Specifically, the reason why the compressor generates noise is because of its own operation. The compressor itself has its own operating frequency, and the vibration generated by the compressor will also combine with the sound signal generated by the compressor, resulting in the superposition of two vibration signals. Therefore, there may be not only noise signals generated by the compressor in the space, but also sound and vibration signals of vibrations generated by the compressor. Therefore, in an embodiment of the present application, the current operating frequency of the compressor can be determined by the operating frequency issued to the compressor by the device equipped with the compressor.

[0060] Based on this, the compressor frequency can be determined by the device equipped with the compressor, and then combined with the noise information obtained by the sound receiving device to determine two sound vibration waveforms, and then a composite ultrasonic signal can be determined for the two vibration signals. It can be seen that through this method, the compressor vibration signal can be further offset, thereby achieving the effect of improving the noise reduction effect.

[0061] In order to better implement the embodiment of the present application, in one embodiment of the present application, the target compressor is set on the target device, and the current operating frequency of the target compressor is determined, including:

[0062] Obtain the current ambient temperature, the target operating cycle of the target device, the first operating time of the target compressor, and the second operating time of the target device; determine the current operating frequency of the target compressor according to the current ambient temperature, the target operating cycle, the first operating time, and the second operating time.

[0063] The above embodiment provides a solution for directly determining the current operating frequency of the compressor according to the equipment installed in the compressor. The embodiment of the present application also provides a solution for determining the operating frequency of the compressor.

[0064] Specifically, the current operating frequency of the compressor may be determined according to the previous ambient temperature, the target operating cycle of the target device, the first operating time of the target compressor, and the second operating time of the target device.

[0065] Among them, the current ambient temperature can be obtained through the ambient temperature sensor, and the second operating time of the target device can be determined as the second operating time by recording the time from the start-up time of the target device to the current time through the timer in the target device. The control logic of the compressor frequency is usually controlled by a periodic function. The target operating cycle of the current compressor can be calculated through the second operating time that has passed in a separate cycle. At the same time, the first operating time can be counted by the timer to count the working time of the compressor, so as to obtain the specific first operating time.

[0066] After obtaining the current ambient temperature, the target operation cycle of the target device, the first operation time of the target compressor, and the second operation time of the target device, the current operating frequency of the compressor can be obtained according to the relevant mapping relationship. The current ambient temperature, the target operation cycle, the first operation time, and the second operation time are input parameters. After the four input parameters are input, the current operating frequency of the compressor can be obtained through the preset mapping relationship.

[0067] In order to better implement the embodiments of the present application, in one embodiment of the present application, controlling the ultrasonic transmitter to transmit a target ultrasonic signal includes:

[0068] Determine a target working area of ​​the target compressor; and control the ultrasonic transmitter to transmit a target ultrasonic signal to the target working area.

[0069] The above embodiment provides a method of transmitting ultrasonic waves to the ambient space. In order to improve the noise reduction effect, in the embodiment of the present application, a positioner can be installed on the compressor, and the position of the compressor can be 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 ultrasonic transmitter can be controlled to point to the position of the locator through the positioning signal sent by the locator, so that the ultrasonic transmitter can be controlled to transmit the target ultrasonic signal to the target working area.

[0071] In order to better implement the embodiments of the present application, in one embodiment of the present application, after controlling the ultrasonic transmitter to transmit the target ultrasonic signal, the method further includes:

[0072] Determine the ambient sound frequency information after noise reduction; and control the operating frequency of the target compressor according to the ambient volume corresponding to the ambient sound frequency information.

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

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

[0075] In order to better implement the embodiment of the present application, in one embodiment of the present application, controlling the operating frequency of the target compressor according to the ambient volume corresponding to the ambient sound frequency information includes:

[0076] If the ambient volume is greater than or equal to the target decibel value, the operating 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 operating frequency of the target compressor is increased.

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

[0078] In order to better implement the embodiments of the present application, in one embodiment of the present application, after controlling the ultrasonic transmitter to transmit the target ultrasonic signal, the method further includes:

[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 parameters corresponding to the target ultrasonic signal, and / or adjust the transmitter parameters of the ultrasonic transmitter to reduce the ambient volume.

[0080] The above embodiment provides a solution that if the ambient volume is still high after noise reduction, the ambient volume can be reduced by adjusting the compressor frequency, but this may affect the cooling effect. Therefore, the embodiment of the present application also provides an implementation method.

[0081] Specifically, the target ultrasonic signal includes not only frequency information but also phase information. Therefore, if the noise reduction effect is not ideal, the signal parameters related to the phase in the target ultrasonic signal can be adjusted to achieve the translation of the target ultrasonic signal. The specific reason is that by adjusting the phase, the peak of the ultrasonic signal can be opposite to the trough of the noise information and the trough of the ultrasonic signal can be opposite to the peak of the noise information. In this way, the noise volume can be minimized by offsetting the trough with the peak.

[0082] In addition, in the embodiment of the present application, multiple ultrasonic transmitters can also be installed. If the noise reduction effect is not ideal, multiple ultrasonic transmitters can be started to emit ultrasonic waves at the same time, thereby increasing the noise reduction effect. Therefore, the transmitter parameters may include the number of transmitters. Alternatively, the transmitter parameters may include the orientation angle of the transmitter. By randomly rotating the emission direction of the transmitter, whenever the direction of the transmitter changes, the current ambient volume is collected, thereby finding the direction of the minimum ambient volume, which is not limited by the specific embodiment of the present application.

[0083] In order to better implement the compressor noise reduction method in the embodiment of the present application, in addition to the compressor noise reduction method, a compressor noise reduction device is also provided in the embodiment of the present application, specifically as follows: Figure 3 As shown, the device 300 includes:

[0086] The control module 303 is used to control the ultrasonic transmitter to transmit a target ultrasonic signal to offset the noise of the target compressor.

[0087] The compressor noise reduction device provided by the present application can first obtain the current noise information emitted by the compressor through the acquisition module 301, and make the determination module 302 determine the target ultrasonic signal that can offset the noise according to the current noise information. Finally, the control module 303 controls the ultrasonic transmitter to emit the target ultrasonic signal, thereby eliminating or reducing the influence of the noise information generated by the compressor and achieving the noise reduction effect.
