Description
Technical Field

[0002] Air pumps are widely used in many products, for example, they play an important role in massage equipment and other related products. In conventional application environments, the noise generated by air pumps has little impact on the overall use effect, so the demand for low noise is not very prominent. However, as the application scenarios of products gradually expand to noise-sensitive fields such as sleeping environments, the problem of air pump noise has become more and more prominent. For example, existing smart mattresses usually include air pumps and several air bags connected to the air pumps. The air bags can be inflated or exhausted by the air pumps to adjust the hardness of the air bags. In this process, when the air pump noise is too loud, it will affect the user's sleep quality. The current treatment methods for air pump noise in the market mainly focus on using sound insulation or sound absorption materials to construct sound insulation structures or devices. However, in some application scenarios with relatively small spaces, such as small massage appliances with limited internal space, the noise reduction effect of sound insulation or sound absorption solutions is greatly reduced, and it is difficult to meet the strict requirements of low noise, resulting in users still being disturbed by air pump noise in scenarios such as sleeping, which greatly affects the product's user experience and market competitiveness.

[0025] Embodiment 1
[0026] Figure 1 A flow chart of an air pump noise reduction control method is provided for Embodiment 1 of the present invention. This embodiment is applicable to the case of silencing an air pump. The method can be applied to an air pump noise reduction control system. The air pump noise reduction control system includes a control center, an air pump module, a silencer box and an airbag module. The silencer box includes a sound-generating module. The air pump module is connected to the inlet end of the silencer box through a first pipe, and the outlet end of the silencer box is connected to the airbag module through a second pipe. The control center is connected to the air pump module, the silencer box and the airbag module respectively, and the method is executed by the control center.
[0027] The control center may be a variety of general and / or special processing components with processing and computing capabilities. Some examples include, but are not limited to, a central processing unit (CPU), a graphics processing unit (GPU), various special artificial intelligence (AI) computing chips, various processors running machine learning model algorithms, a digital signal processor (DSP), and any appropriate processor, controller, microcontroller, etc.
[0028] like Figure 1 As shown, the method includes:
[0029] S110, obtaining a target air pump control mode to be adjusted and a pre-built air pump silencing model.
[0030] In this embodiment, the target air pump control mode can be understood as the air pump working mode adopted in this adjustment. The air pump control mode can be set according to different working intensities of the air pump, for example, it can be set by working power, and different control modes can be set according to different percentages of working power.
[0031] In this embodiment, due to the different air pump control modes, the noise generated is different, that is, the corresponding silencing parameters for different noise conditions are different. The air pump silencing model includes models of silencing parameters corresponding to different air pump control modes.
[0032] Specifically, the control center can obtain the air pump control mode to be adjusted input by the user. For example, the control center can guide the user to select different pre-set air pump control modes by setting buttons, etc., so that the control center can receive the air pump control mode to be adjusted selected by the user, and a pre-built air pump silencing model can be stored in the storage medium.
[0033] S120, determining an air pump control instruction and a silencer control instruction according to a target air pump control mode and an air pump silencer model.
[0034] In this embodiment, the air pump control instruction can be understood as an instruction for controlling the air pump module to work according to the parameters. The mute control instruction can be understood as an instruction for controlling the sound module in the mute box to work according to the parameters.
[0035] Specifically, since different air pump control modes correspond to different air pump control parameters at the stage of air pump control mode setting, the control center can determine the air pump control parameters corresponding to the target air pump control mode and generate air pump control instructions. The control center can search for the silencer parameters corresponding to the target air pump control mode in the air pump silencer model to generate the silencer control instructions through the silencer parameters.
[0036] S130, transmitting the air pump control instruction to the air pump module, and transmitting the silencer control instruction to the sound generator module, so that the air pump module generates gas according to the air pump control instruction and flows into the airbag module after silenced by the silencer box, and the sound generator module generates canceling noise according to the silencer control instruction.
[0037] In this embodiment, the noise cancellation can be understood as the sound emitted by the sound generating module to cancel the working noise of the air pump.
[0038] Specifically, the control center can transmit the air pump control instruction to the air pump module, and transmit the silencing control instruction to the sound module, so that the air pump module can generate gas according to the parameters (such as working power) in the air pump control instruction, the gas flows into the silencer box from the inlet end of the silencer box through the first pipeline, and the sound module in the silencer box emits a counteracting noise according to the silencing control instruction to offset the noise generated when the air pump module is working. The interior of the silencer box can be made of silencing material. Since the interior of the silencer box is a closed space environment, the counteracting effect can be enhanced. The gas flows into the airbag module through the second channel at the outlet end of the silencer box to achieve inflation of the airbag module.
[0039] The technical solution of the embodiment of the present invention is applied to an air pump noise reduction control system, which includes a control center, an air pump module, a silencer box and an airbag module, wherein the silencer box includes a sound-generating module, the air pump module is connected to the inlet end of the silencer box through a first pipe, and the outlet end of the silencer box is connected to the airbag module through a second pipe, and the control center is connected to the air pump module, the silencer box and the airbag module respectively. The method is executed by the control center, and the method includes: obtaining a target air pump control mode to be adjusted and a pre-built air pump silencer model; determining an air pump control instruction and a silencer control instruction according to the target air pump control mode and the air pump silencer model; transmitting the air pump control instruction to the air pump module, and transmitting the silencer control instruction to the sound-generating module, so that the air pump module generates gas according to the air pump control instruction and flows into the airbag module after silenced by the silencer box, and the sound-generating module generates a counteracting noise according to the silencer control instruction. By arranging a silencer box at the rear stage of the air pump, a sound-generating device is arranged in the silencer box. The noise canceling device emits a noise with the same frequency, amplitude and opposite phase as the detected noise in real time, which effectively reduces the noise generated by the air pump during operation. This improves the universality of the air pump silencing and the silencing effect in different scenarios. It significantly improves the performance of the air pump in scenarios with strict noise requirements such as sleeping.
[0040] Further, based on the above embodiment, the steps of determining the air pump control instruction and the silencer control instruction according to the target air pump control mode and the air pump silencer model can be refined as follows:
[0041] According to the target air pump control mode, the air pump control parameters are determined and the air pump control instructions are generated; the silencer parameters matching the target air pump control mode are determined in the air pump silencer model; and the silencer control instructions are generated according to the silencer parameters.
[0042] In this embodiment, the air pump control parameter can be understood as the control parameter corresponding to the target air pump control mode, for example, the air pump control parameter includes different working powers and starting times, for example, the air pump control parameter corresponding to air pump control mode 1 is full power 100%, that is, the fastest inflation; the air pump control parameter (working power) corresponding to air pump control mode 2 is 90%; the air pump control parameter (working power) corresponding to air pump control mode 3 is 80%; the air pump control parameter (working power) corresponding to air pump control mode 4 is 70%; the air pump control parameter (working power) corresponding to air pump control mode 5 is 60%; the air pump control parameter (working power) corresponding to air pump control mode 6 is 50%. The silencing parameter can be understood as the basis for the sound module to make a sound, for example, it may include the maximum amplitude of the sound, the center frequency and the time interval, wherein the starting time of the sound module is determined by the time interval and the starting time of the air pump noise reduction control system.
[0043] Specifically, the control center can search for corresponding air pump control parameters and generate corresponding air pump control instructions for the air pump noise reduction control system according to the target air pump control mode through a pre-established parameter comparison table or the like. The control center can determine the silencing parameters that match the target air pump control mode in the air pump silencing model, and generate a silencing control instruction for controlling the sound module through the start time of the air pump noise reduction control system in the air pump control instruction.
[0044] As a first optional embodiment of the present embodiment 1, based on the above embodiment, during the construction stage of the air pump silencer model, the silencer box further includes a collection module.
[0045] Among them, the construction stage of the air pump silencing model can be set before leaving the factory, and a collection module can be added to the silencing box. The collection module collects the working noise from the air pump module and the working noise of the sound module in the silencing box respectively, and then the air pump silencing model is constructed through the working noise. In actual application, there is no need to include the collection module, and the air pump silencing model that has been constructed can be directly used.
[0046] For example, in order to make the composition of the air pump noise reduction control system in the air pump noise reduction model construction stage of the present invention clearer, a specific example can be used for demonstration. Figure 2 A schematic diagram of the structure of an air pump noise reduction control system in an air pump noise reduction control method provided in Embodiment 1 of the present invention, such as Figure 2As shown, the air pump noise reduction control system includes: a control center 21, an air pump module 22, a silencer box 23 and an airbag module 24, the silencer box includes a sound module 231 and a collection module 232, the air pump module 22 is connected to the inlet end of the silencer box 23 through a first pipe, the outlet end of the silencer box 23 is connected to the airbag module 24 through a second pipe, the control center 21 is connected to the air pump module 22, the collection module 232 and the sound module 231 in the silencer box 23 and the airbag module 24 respectively, so as to transmit electrical signals through electrical connection.
[0047] Further, based on the above embodiment, the steps of constructing the air pump silencing model include:
[0048] Acquire the air pump control mode set and the air pump attribute information of the air pump module; determine the sample signal set according to the air pump control mode set, the air pump attribute information and the acquisition module; determine the silencing parameters according to the sample signal set and form an air pump silencing model.
[0049] In this embodiment, the air pump control mode set can be understood as a pre-set set of all air pump control modes, that is, including the air pump control modes 1-6 mentioned in the above example. The air pump includes a motor and a plurality of pistons, and the air pump attribute information can be understood as attributes related to the operation of the air pump, such as the maximum speed of the motor and the number of piston cylinders. The sample signal set can be understood as a set of noise signals when the air pump module works in different air pump control modes, and noise signals when the corresponding sound module works.
[0050] Specifically, the control center can obtain the air pump control mode set and the air pump attribute information of the air pump module, first determine the noise parameters generated when the air pump is working under each air pump control mode, and then determine the noise cancellation parameters corresponding to the sound module in theory. The control center can control the air pump module according to the air pump control parameters corresponding to the air pump control mode. First, the noise sample signal when the air pump module is working is obtained through the acquisition module; then the sound module is controlled by the noise cancellation parameters, and the noise sample signal when the sound module is working is obtained through the acquisition module. The noise cancellation parameters are corrected through the two noise sample signals, and the final corrected silencing parameters are obtained after the noise reduction standard is met. After determining the silencing parameters corresponding to all air pump control modes, the control center can form an air pump silencing model by associating each silencing parameter with the corresponding air pump control mode.
[0051] Furthermore, the steps of determining the sample signal set according to the air pump control mode set, the air pump attribute information and the acquisition module can be refined as follows:
[0052] According to the air pump control modes and air pump attribute information in the air pump control mode set, the air pump control parameters and initial silencer control parameters are determined; the air pump module is controlled according to the air pump control parameters, and a first sample signal is obtained through the acquisition module; the sound module is controlled according to the initial silencer control parameters, and a second sample signal is obtained through the acquisition module; and a sample signal set is determined based on the first sample signal and the second sample signal.
[0053] In this embodiment, the initial noise reduction control parameter can be understood as an uncorrected theoretical noise reduction control parameter. Since the actual usage may cause the parameter to deviate from the theoretical value, correction is required. The first sample signal can be understood as the noise signal generated when only the air pump module is working. The second sample signal can be understood as the noise signal generated when only the sound module is working.
[0054] Specifically, the control center can determine in sequence according to the silencing parameters corresponding to each air pump control mode in the air pump control mode set. The control center can first determine the air pump control parameters corresponding to the air pump control mode, and determine the initial silencing control parameters according to the air pump control parameters and theory. Since the noise signal generated by the air pump module when it is working is very similar to the noise signal generated by the sound module and is not easy to distinguish, they can be controlled and collected in sequence. The control center can control the air pump module according to the air pump control parameters, and obtain the first sample signal through the acquisition module; control the sound module according to the initial silencing control parameters, and obtain the second sample signal through the acquisition module. The control module can use the first sample signal and the second sample signal as the sample signal set under the air pump control mode.
[0055] Among them, the steps of determining the air pump control parameters and the initial silencing control parameters according to the air pump control modes and air pump attribute information in the air pump control mode set can be refined as follows:
[0056] Determine the center frequency under the air pump control mode according to the air pump control parameters corresponding to the air pump control mode combined with the maximum motor speed and the total number of cylinders in the air pump attribute information; determine the maximum amplitude at the center frequency; use the maximum amplitude, center frequency and air pump start-up time as air pump parameter characteristics; determine the initial silencer control parameters according to the air pump parameter characteristics and the preset initial time interval.
[0057] In this embodiment, the maximum motor speed can be understood as the maximum speed of the motor. The total number of cylinders can be understood as the number of piston cylinders included in the air pump. The center frequency can be understood as the maximum frequency value. The maximum amplitude can be understood as the amplitude value corresponding to the center frequency. The air pump start time can be understood as the start time used to characterize the air pump module. The air pump parameter characteristics can be understood as the characteristics used to characterize the noise generated by the air pump. The preset initial time interval can be understood as the time interval between the start time of the uncorrected air pump module and the sound module, for example, it can be set to π or 0, etc.
[0058] Specifically, the control center can determine the center frequency under the air pump control mode and the maximum amplitude at the center frequency according to the air pump control parameters corresponding to the air pump control mode and the maximum motor speed and the total number of cylinders in the air pump attribute information, wherein the maximum amplitude can be obtained by the amplitude value corresponding to the center frequency of the first sample signal collected. The control center can use the maximum amplitude, center frequency and air pump start time as air pump parameter characteristics. The controller can determine the initial silencing control parameters according to the air pump parameter characteristics and the preset initial time interval.
[0059] Exemplarily, the center frequency can be calculated by the following formula:
[0060]
[0061] Among them, F is the center frequency, R is the maximum motor speed, a is the working state (i.e. the working power percentage), and b is the total number of cylinders.
[0062] For example, in the above air pump control mode 1, power: 100%, maximum motor speed: 5000r / min, when the piston is 4 cylinders, the center frequency of the noise generated is:
[0063]
[0064] For example, in the above-mentioned air pump control mode 2, the power is 90%, the maximum motor speed is 5000r / min, and the piston is 4 cylinders, the center frequency of the noise generated is:
[0065]
[0066] Among them, the steps of determining the silencing parameters and forming the air pump silencing model according to the sample signal set can be refined as follows:
[0067] According to the first sample signal, the first phase of the air pump module is determined; according to the second sample signal, the second phase of the sound module is determined; according to the phase difference between the first phase and the second phase, it is judged whether the preset target phase difference is reached. If so, the initial mute control parameter is used as the mute parameter, and an air pump mute model is constructed based on the mute parameter and the air pump control parameter; if not, the preset initial time interval in the initial mute control parameter is adjusted to obtain the current time interval to update the initial mute control parameter, and return to the step of obtaining the first sample signal and the second sample signal.
[0068] In this embodiment, the first phase can be understood as the phase corresponding to the start-up time of the air pump module. The second phase can be understood as the phase corresponding to the start-up time of the sound module.
[0069] It is understandable that in theory, the noise cancellation parameters should have the same frequency characteristics as the noise parameters, but the phase difference is π. In actual use, the time of electrical signals or module responses is slightly different, which makes it impossible to strictly control the phase difference to the theoretical value. The phase difference can be corrected through the sample signal set. The preset target phase difference can be understood as the phase difference value that forms noise cancellation, that is, the π mentioned above. The current time interval can be understood as the adjusted time interval.
[0070] Specifically, the control center can determine the first phase of the air pump module according to the first sample signal and the start-up time of the air pump module. The control center can determine the second phase of the sound module according to the second sample signal and the start-up time of the sound module. The control center can determine whether the preset target phase difference is reached according to the phase difference between the first phase and the second phase. If so, the initial silencing control parameter is used as the silencing parameter, and the air pump silencing model is constructed based on the silencing parameter and the air pump control parameter; if not, the preset initial time interval in the initial silencing control parameter is adjusted. For example, the actual phase difference between the first phase and the second phase is 3 / 4π, and the difference between the preset target phase difference π is 1 / 4π. The corresponding relationship between phase and time can be used to take 1 / 4π as the adjustment target, and the preset initial time interval is adjusted to obtain the current time interval to update the initial silencing control parameter, so as to use the current time interval as the silencing control parameter of the sound module, and return to the acquisition step of the first sample signal and the second sample signal, and re-acquire the first sample signal and the second sample signal to determine whether the preset target phase difference is reached after the current time interval control.
[0071] Among them, there may be a situation where the center frequency and maximum amplitude of the actual second sample signal of the sound module when making a sound are different from the silencer control parameters, or there may be a situation where the first sample signal when the air pump module actually generates noise is different from the air pump parameter characteristics calculated theoretically. The control center can also determine the first deviation between the actual air pump parameter characteristics in the first sample signal and the theoretical air pump parameter characteristics, and determine the second deviation between the actual parameter characteristics in the second sample signal and the theoretical silencer control parameters. The maximum amplitude and center frequency in the silencer control parameters are adjusted according to the first deviation and the second deviation to ensure the effect of canceling the noise.
[0072] The first optional embodiment of the first embodiment of the present invention is to add a collection module to the silencer box, collect the first sample signal corresponding to the noise generated by the air pump module of the silencer box, and collect the second sample signal corresponding to the noise generated by the internal sound module, so as to form an actual sample signal set, and correct the initial silencer control parameters set by theory through the sample signal set to obtain the actual silencer parameters, and establish an association between the actual silencer parameters and the corresponding air pump control mode to form an air pump silencer model. The silencer parameters are more in line with the actual working scene, the error of the silencer parameters is reduced, and the silencer effect is improved.

The noise canceling device emits a noise with the same frequency, amplitude and opposite phase as the detected noise in real time, which effectively reduces the noise generated by the air pump during operation. This improves the universality of the air pump silencing and the silencing effect in different scenarios. It significantly improves the performance of the air pump in scenarios with strict noise requirements such as sleeping.
