Description

A method, system, medium, and product for noise reduction control of an air pump. Technical Field

[0001] This invention relates to the field of air pump technology, and in particular to an air pump noise reduction control method, system, medium, and product. Background Technology

[0002] Air pumps are widely used in many products, playing a vital role in massage devices and other related products. In typical applications, the noise generated by air pumps has a relatively small impact on the overall user experience, so the need for low noise is not particularly prominent. However, as product applications expand into noise-sensitive areas such as sleep environments, the issue of air pump noise becomes increasingly apparent. For example, existing smart mattresses typically include an air pump and several air chambers connected to it. The air pump inflates or deflates these chambers to adjust their firmness. Excessive air pump noise during this process can affect the user's sleep quality. Current market solutions for air pump noise primarily focus on constructing soundproofing structures or devices using sound-absorbing or sound-insulating materials. However, in confined spaces, such as the limited internal space of small massage devices, the noise reduction effect of soundproofing or sound-absorbing solutions is significantly reduced, failing to meet stringent low-noise requirements. This results in users still being disturbed by air pump noise during sleep and other scenarios, greatly impacting the product's user experience and market competitiveness. Summary of the Invention

[0025] Example 1

[0026] Figure 1 is a flowchart of an air pump noise reduction control method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of air pump silencing. 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. 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. The method is executed through the control center.

[0027] The control center can be any general-purpose and / or dedicated processing component with processing and computing capabilities. Some examples include, but are not limited to, a central processing unit (CPU), a graphics processing unit (GPU), various dedicated artificial intelligence (AI) computing chips, various processors running machine learning model algorithms, digital signal processors (DSPs), and any suitable processor, controller, microcontroller, etc.

[0028] As shown in Figure 1, the method includes:

[0029] S110, Obtain the target air pump control mode to be adjusted and the pre-built air pump silencing model.

[0030] In this embodiment, the target air pump control mode can be understood as the air pump operating mode adopted in this adjustment. The air pump control mode can be set according to different operating intensities of the air pump, for example, by setting the operating power, and setting different control modes according to different percentages of the operating power.

[0031] In this embodiment, the noise generated is different due to the different air pump control modes. That is, the silencing parameters are different for different noise conditions. 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, it can guide the user to select different pre-set air pump control modes through setting buttons, so that the control center can receive the air pump control mode to be adjusted selected by the user. The storage medium can store a pre-built air pump silencing model.

[0033] S120. Based on the target air pump control mode and air pump silencing model, determine the air pump control command and silencing control command.

[0034] In this embodiment, the air pump control command can be understood as a command to control the air pump module to operate according to parameters. The silencing control command can be understood as a command to control the sound-generating module in the silencer box to operate according to parameters.

[0035] Specifically, during the air pump control mode setting phase, different air pump control modes correspond to different air pump control parameters. The control center can determine the air pump control parameters corresponding to the target air pump control mode and generate air pump control commands. The control center can also search for the silencing parameters corresponding to the target air pump control mode in the air pump silencing model to generate silencing control commands based on these parameters.

[0036] S130: The air pump control command is transmitted to the air pump module, and the silencing control command is transmitted to the sound generation module, so that the air pump module generates gas according to the air pump control command, and the gas flows into the airbag module after being silenced by the silencing box. The sound generation module generates noise cancellation according to the silencing control command.

[0037] In this embodiment, noise cancellation can be understood as the sound emitted by the sound-generating module to cancel the noise of the air pump.

[0038] Specifically, the control center can transmit air pump control commands to the air pump module and silencing control commands to the sound-generating module. This allows the air pump module to generate gas according to the parameters (e.g., operating power) in the air pump control commands. The gas flows into the silencing box through a first pipe from the inlet end. The sound-generating module within the silencing box then emits noise cancellation power according to the silencing control commands, effectively counteracting the noise generated by the air pump module. The silencing box can be constructed of sound-absorbing material. Because the silencing box is a closed space, the cancellation effect is enhanced. The gas then flows into the airbag module through a second channel at the outlet end of the silencing box, inflating the airbag module.

[0039] The technical solution of this invention is 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 via a first pipe, and the outlet end of the silencer box is connected to the airbag module via a second pipe. 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 includes: acquiring the target air pump control mode to be adjusted and a pre-constructed air pump silencer model; determining air pump control commands and silencer control commands based on the target air pump control mode and the air pump silencer model; transmitting the air pump control commands to the air pump module and the silencer control commands to the sound-generating module, so that the air pump module generates gas according to the air pump control commands, which flows into the airbag module after being silenced by the silencer box, and the sound-generating module generates noise cancellation according to the silencer control commands. A silencer box is set after the air pump, and a sound-generating device is installed inside the silencer box. The system emits noise in real time that has the same frequency and amplitude as the monitored noise but opposite phase, effectively reducing the noise generated by the air pump during operation. This improves the versatility of air pump noise reduction and enhances the noise reduction effect in different scenarios. It significantly improves the performance of the air pump in scenarios with stringent noise requirements, such as sleep environments.

[0040] Furthermore, based on the above embodiments, the steps of determining the air pump control command and the silencer control command according to the target air pump control mode and the air pump silencer model can be refined as follows:

[0041] Based on the target air pump control mode, determine the air pump control parameters and generate air pump control commands; determine the silencing parameters that match the target air pump control mode in the air pump silencing model; and generate silencing control commands based on the silencing parameters.

[0042] In this embodiment, the air pump control parameters can be understood as control parameters corresponding to the target air pump control mode. For example, the air pump control parameters include different operating power and start time. For instance, the air pump control parameter corresponding to air pump control mode 1 is 100% full power, i.e., the fastest inflation; the air pump control parameter (operating power) corresponding to air pump control mode 2 is 90%; the air pump control parameter (operating power) corresponding to air pump control mode 3 is 80%; the air pump control parameter (operating power) corresponding to air pump control mode 4 is 70%; the air pump control parameter (operating power) corresponding to air pump control mode 5 is 60%; and the air pump control parameter (operating power) corresponding to air pump control mode 6 is 50%. The noise reduction parameters can be understood as the basis for the sound generation module to generate sound, such as the maximum amplitude of sound generation, center frequency, and time interval. The start time of the sound generation module is determined by the time interval and the start time of the air pump noise reduction control system.

[0043] Specifically, the control center can look up the corresponding air pump control parameters based on the target air pump control mode using a pre-established parameter lookup table and generate corresponding air pump control commands for the air pump noise reduction control system. The control center can determine the noise reduction parameters matching the target air pump control mode in the air pump noise reduction model and generate noise reduction control commands for controlling the sound-generating module based on the start time of the air pump noise reduction control system in the air pump control commands.

[0044] As a first optional embodiment of this embodiment, based on the above embodiment, in the construction stage of the air pump silencing model, the silencing box also includes a data acquisition module.

[0045] The construction phase of the air pump silencing model can be set before shipment, by adding a data acquisition module to the silencing box. This module collects the operating noise from both the air pump module and the sound-generating module within the silencing box, and then uses this operating noise to construct the air pump silencing model. In practical applications, however, the data acquisition module is unnecessary; the pre-constructed air pump silencing model can be used directly.

[0046] For example, to more clearly illustrate the composition of the air pump noise reduction control system in the air pump noise reduction model construction stage of the present invention, a specific example can be shown. Figure 2 is a schematic diagram of the structure of the air pump noise reduction control system in an air pump noise reduction control method provided in Embodiment 1 of the present invention. As shown in Figure 2, the air pump noise reduction control system includes: a control center 21, an air pump module 22, a noise reduction box 23, and an airbag module 24. The noise reduction box includes a sound-generating module 231 and a data acquisition module 232. The air pump module 22 is connected to the inlet end of the noise reduction box 23 through a first pipe, and the outlet end of the noise reduction 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 data acquisition module 232 and the sound-generating module 231 in the noise reduction box 23, and the airbag module 24 respectively, so as to transmit electrical signals through electrical connection.

[0047] Furthermore, based on the above embodiments, the construction steps of the air pump silencer model include:

[0048] Acquire the air pump control mode set and air pump attribute information of the air pump module; determine the sample signal set based on the air pump control mode set, air pump attribute information and acquisition module; determine the silencing parameters and form the air pump silencing model based on the sample signal set.

[0049] In this embodiment, the air pump control mode set can be understood as a pre-defined set containing all air pump control modes, i.e., including air pump control modes 1-6 mentioned in the above example. The air pump includes a motor and several pistons. The air pump attribute information can be understood as attributes related to the air pump's operation, such as the maximum motor speed and the number of piston cylinders. The sample signal set can be understood as a set including noise signals from the air pump module operating under different air pump control modes, and noise signals from the corresponding sound-generating module operating.

[0050] Specifically, the control center can acquire the air pump control mode set and air pump attribute information of the air pump module. First, it determines the noise parameters generated by the air pump during operation under each control mode, and then determines the theoretical noise cancellation parameters corresponding to the sound-generating module. The control center can control the air pump module according to the air pump control parameters corresponding to the air pump control mode. First, it acquires noise sample signals of the air pump module during operation through the acquisition module; then, it controls the sound-generating module using the noise cancellation parameters, acquiring noise sample signals of the sound-generating module during operation through the acquisition module. The noise cancellation parameters are corrected using the two noise sample signals, and the final corrected noise reduction parameters are obtained after reaching the noise reduction standard. After determining the noise reduction parameters corresponding to all air pump control modes, the control center can establish a correlation between each noise reduction parameter and the corresponding air pump control mode to form an air pump noise reduction model.

[0051] Furthermore, the steps for determining the sample signal set based on the air pump control mode set, air pump attribute information, and acquisition module can be refined as follows:

[0052] Based on the air pump control modes and air pump attribute information in the air pump control mode set, determine the air pump control parameters and initial silencing control parameters; control the air pump module according to the air pump control parameters, and acquire the first sample signal through the acquisition module; control the sound generation module according to the initial silencing control parameters, and acquire the second sample signal through the acquisition module; determine the sample signal set based on the first sample signal and the second sample signal.

[0053] In this embodiment, the initial noise reduction control parameters can be understood as uncorrected theoretical noise reduction control parameters. Since actual usage can cause deviations between the parameters and theoretical values, correction is necessary. The first sample signal can be understood as the noise signal generated only when the air pump module is operating. The second sample signal can be understood as the noise signal generated only when the sound-generating module is operating.

[0054] Specifically, the control center can sequentially determine the silencing parameters corresponding to each air pump control mode in the air pump control mode set. First, the control center can determine the air pump control parameters corresponding to the air pump control mode, and then determine the initial silencing control parameters based on these parameters and theoretical principles. Since the noise signal generated by the air pump module during operation is extremely similar to the noise signal generated by the sound-generating module, making them difficult to distinguish, control and data acquisition can be performed sequentially. The control center can control the air pump module according to the air pump control parameters and acquire the first sample signal through the acquisition module; it can also control the sound-generating module according to the initial silencing control parameters and acquire the second sample signal through the acquisition module. The control module can use the first and second sample signals as the sample signal set for that air pump control mode.

[0055] The steps for determining the air pump control parameters and initial silencer control parameters based on the air pump control modes and air pump attribute information in the air pump control mode set can be further refined as follows:

[0056] Based on 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, the center frequency in the air pump control mode is determined; the maximum amplitude at the center frequency is determined; the maximum amplitude, center frequency, and air pump start time are used as air pump parameter characteristics; and the initial silencing control parameters are determined based on 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-up time can be understood as the start-up 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-up time of the uncorrected air pump module and the sound-generating module, for example, it can be set to π or 0.

[0058] Specifically, the control center can determine the center frequency under the air pump control mode based on the air pump control parameters corresponding to the air pump control mode, combined with the maximum motor speed and total number of cylinders in the air pump attribute information. The maximum amplitude at this center frequency can be determined by the amplitude value corresponding to the center frequency of the first sample signal. The control center can use the maximum amplitude, center frequency, and air pump start-up time as air pump parameter characteristics. The controller can then determine the initial noise reduction control parameters based on these air pump parameter characteristics and a preset initial time interval.

[0059] For example, the center frequency can be calculated using the following formula:

[0060]

[0061] Where F is the center frequency, R is the maximum motor speed, a is the working state (i.e., working power percentage), and b is the total number of cylinders.

[0062] For example, under the above air pump control mode 1, with power at 100%, maximum motor speed at 5000 r / min, and a 4-cylinder piston system, the center frequency of the noise generated is:

[0063]

[0064] For example, under the above-mentioned air pump control mode 2, with power at 90%, maximum motor speed of 5000 r / min, and a 4-cylinder piston system, the center frequency of the noise generated is:

[0065]

[0066] The steps of determining the silencing parameters and forming the air pump silencing model based on the sample signal set can be further refined as follows:

[0067] Based on the first sample signal, determine the first phase of the air pump module; based on the second sample signal, determine the second phase of the sound-generating module; determine whether the preset target phase difference has been reached based on the phase difference between the first phase and the second phase. If so, use the initial silencing control parameters as silencing parameters, and construct an air pump silencing model based on the silencing parameters and the air pump control parameters; otherwise, adjust the preset initial time interval in the initial silencing control parameters to obtain the current time interval to update the initial silencing control parameters, and return to the steps 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-generating module.

[0069] It is understandable that, theoretically, the noise cancellation parameters should have the same frequency characteristics as the noise parameters, but with a phase difference of π. However, in actual use, there are slight differences in the response time of electrical signals or modules, making it impossible to strictly control the phase difference to the theoretical value. Therefore, the phase difference can be corrected using a sample signal set. The preset target phase difference can be understood as the phase difference value that achieves noise cancellation, i.e., 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 based on 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-generating module based on the second sample signal and the start-up time of the sound-generating module. The control center can determine whether the preset target phase difference has been reached based on the phase difference between the first and second phases. If so, the initial silencing control parameters are used as silencing parameters, and an air pump silencing model is constructed based on the silencing parameters and the air pump control parameters. If not, the preset initial time interval in the initial silencing control parameters is adjusted. For example, if the actual phase difference between the first and second phases is 3 / 4π, then the difference from the preset target phase difference π is 1 / 4π. The current time interval is obtained by adjusting the preset initial time interval using the correspondence between phase and time, with 1 / 4π as the adjustment target, to update the initial silencing control parameters. The current time interval is then used as the silencing control parameter for the sound-generating module. The control center then returns to the steps of acquiring the first and second sample signals, re-acquiring the first and second sample signals to determine whether the preset target phase difference has been reached after control using the current time interval.

[0071] There may be situations where the center frequency and maximum amplitude of the actual second sample signal of the sound-generating module differ from the noise reduction control parameters, or the first sample signal of the air pump module when actually generating noise differs from the theoretically calculated air pump parameter characteristics. The control center can also determine the first deviation between the actual air pump parameter characteristics and the theoretical air pump parameter characteristics in the first sample signal, and determine the second deviation between the actual parameter characteristics and the theoretical noise reduction control parameters in the second sample signal. The maximum amplitude and center frequency in the noise reduction control parameters are adjusted based on the first and second deviations to ensure the noise cancellation effect.

[0072] In the first optional embodiment of this first example, a data acquisition module is added to the silencer box to collect a first sample signal corresponding to the noise generated by the silencer box's air pump module and a second sample signal corresponding to the noise generated by the internal sound-generating module, forming an actual sample signal set. This sample signal set is then used to correct the theoretically set initial silencing control parameters to obtain the actual silencing parameters. Furthermore, a correlation is established between the actual silencing parameters and the corresponding air pump control mode to form an air pump silencing model. This makes the silencing parameters more closely match the actual working scenario, reduces the error of the silencing parameters, and thus improves the silencing effect.

[0073] Example 2

[0074] Figure 3 is a schematic diagram of an air pump noise reduction control system provided in Embodiment 2 of the present invention. As shown in Figure 3, the system includes: a control center 31, an air pump module 32, a silencer box 33, and an airbag module 34. The silencer box 33 includes a sound-generating module 331. The air pump module 32 is connected to the inlet end of the silencer box 33 through a first pipe, and the outlet end of the silencer box 33 is connected to the airbag module 34 through a second pipe. The control center 31 is connected to the air pump module 32, the silencer box 33, and the airbag module 34 respectively.

[0075] The control center 31 is used to acquire the target air pump control mode to be adjusted and the pre-built air pump silencing model.

[0076] Based on the target air pump control mode and the air pump silencing model, determine the air pump control command and the silencing control command;

[0077] The air pump control command is transmitted to the air pump module 32, and the noise reduction control command is transmitted to the sound generation module 331;

[0078] The air pump module 32 is used to generate gas according to the air pump control command and flow into the silencer box 33 through the first pipe;

[0079] The sound-generating module 331 is used to generate noise cancellation according to the noise reduction control command, so as to reduce the noise inside the noise reduction box 33;

[0080] The airbag module 34 is used to inflate the airbag by introducing gas through the second pipe.

A silencer box is set after the air pump, and a sound-generating device is set inside the silencer box. The system emits noise in real time that has the same frequency and amplitude as the monitored noise but opposite phase, effectively reducing the noise generated by the air pump during operation. This improves the versatility of air pump noise reduction and enhances the noise reduction effect in different scenarios. It significantly improves the performance of the air pump in scenarios with stringent noise requirements, such as sleep environments.
