[0053] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vibration signal filtering device, etc. The following takes the vibration signal filtering device as an example to illustrate this embodiment and the following embodiments.

[0054] Based on this, the embodiment of the present application provides a vibration signal filtering method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vibration signal filtering method of the present application.

[0055] In this embodiment, the vibration signal filtering method includes steps S10 to S40:

[0056] Step S10: when it is determined that the target measurement device picks up the current measurement signal, the current noise signal of the heat dissipation device is acquired through the target sound pickup device array.

[0057] It should be noted that the target measurement device can be an inertial measurement unit (IMU), which is used to pick up measurement signals at different times in real time, for example, picking up the current measurement signal at time A. The application scenario of this embodiment is a scenario where the operation of the heat dissipation device affects the target measurement device. Therefore, the current measurement signal is mixed with the vibration signal generated by the operation of the heat dissipation device.

[0058] It should be understood that the target sound pickup device array refers to an array composed of multiple target sound pickup devices, and the target sound pickup device may be a microphone (MIC). The current noise signal refers to the noise signal generated when the heat dissipation device is running, and the heat dissipation device may be a fan.

[0059] Further, step S10 includes: when it is determined that the target measurement device picks up the current measurement signal, obtaining a beam formed by multiple target sound pickup devices through a target sound pickup device array; determining the direction of the beam; and obtaining a current noise signal generated by the heat dissipation device during operation according to the beam and the direction.

[0060] It can be understood that each target sound pickup device will pick up the noise signal of the heat dissipation device. During the picking process, the signals will be continuously superimposed to form a beam. The direction refers to the direction of the beam movement, which can be the direction of the heat dissipation device. After determining the beam and direction, multiple target sound pickup devices are used to obtain the current noise signal generated by the heat dissipation device during operation.

[0061] Furthermore, the step of determining the direction of the beam includes: obtaining the position of a heat dissipation device and the positions of a plurality of target sound pickup devices; determining a relative position according to the position of the heat dissipation device and the positions of the plurality of target sound pickup devices; determining a connection direction of the plurality of target sound pickup devices; and determining the direction of the beam according to the relative position and the connection direction.

[0062] It should be understood that the relative position refers to the position of the heat dissipation device relative to the plurality of target sound pickup devices, for example, Figure 2 , Figure 2 It is a schematic diagram of the device position, specifically: taking two target sound pickup devices as an example, they are target sound pickup device 1 and target sound pickup device 2, the target sound pickup device 1 is located on the lower left side of the heat dissipation device, and the target sound pickup device 2 is located on the lower right side of the heat dissipation device. At this time, the connection direction of the target sound pickup device 1 and the target sound pickup device 2 is horizontal, and the relative position at this time can be that the heat dissipation device is located in a direction perpendicular to the connection direction, and at this time the beam points to the heat dissipation device.

[0063] Furthermore, the step of acquiring the current noise signal generated by the heat dissipation device when it is running according to the beam and the direction includes: acquiring the noise signal picked up by each target sound pickup device according to the beam and the direction; counting the number of target sound pickup devices; and determining the current noise signal generated by the heat dissipation device when it is running according to the number and the noise signal picked up by each target sound pickup device.

[0064] It can be understood that for each target sound pickup device, the noise signal generated when the heat dissipation device is in operation will be picked up. For example, the noise signal picked up by the target sound pickup device 1 is N1, and the noise signal picked up by the target sound pickup device 2 is N2. Then, the current noise signal generated when the heat dissipation device is in operation is determined based on the number of target sound pickup devices counted. For example, when the number of target sound pickup devices Total = 2, the current noise signal N generated when the heat dissipation device is in operation is N = (N1 + N2) / 2.

[0065] Step S20: determining the vibration signal mixed in the current measurement signal according to the current noise signal.

[0066] It should be understood that since the heat dissipation device generates a vibration signal while generating a noise signal during operation, and there is a certain correlation between the vibration signal and the noise signal, the correlation function is stored in the target chip in the form of a data table. When determining the current noise signal generated by the heat dissipation device during operation, the vibration signal mixed in the current measurement signal is inferred through the vibration signal-noise signal correlation function.

[0067] Step S30: filtering the vibration signal from the current measurement signal.

[0068] It is understandable that after the vibration signal is obtained, the vibration signal is filtered out from the current measurement signal. At this time, the current measurement signal no longer contains the vibration signal of the heat dissipation device, thereby avoiding interference with the target measurement device.

[0069] Further, step S30 includes: respectively acquiring characteristic information of the vibration signal and characteristic information of the current measurement signal; determining a target filtering device according to the characteristic information of the vibration signal and the characteristic information of the current measurement signal; setting parameters of the target filtering device; and filtering the vibration signal from the current measurement signal by using the target filtering device after setting the parameters.

[0070] It should be understood that in order to effectively improve the accuracy of filtering out vibration signals, it is necessary to determine the target filtering device based on the characteristic information of the vibration signal and the characteristic information of the current measurement signal, that is, the target filtering device can filter out the vibration signal in the current measurement signal without causing any impact on the current measurement signal. The type of the target filtering device can be a least mean square (Least Mean Squares, LMS) type. At this time, the parameters of the target filtering device set include but are not limited to adjusting the step size factor and the initial coefficient, and then the target filtering device after setting the parameters is used to filter out the vibration signal from the current measurement signal.

[0071] Furthermore, after step S30, it also includes: obtaining the actual purpose of the current measurement signal; determining the measurement signal receiving application according to the actual purpose, and obtaining the signal format of the measurement signal received by the measurement signal receiving application; when the format of the filtered current measurement signal is inconsistent with the signal format, performing format conversion on the filtered current measurement signal to obtain a target measurement signal; establishing a connection with the measurement signal receiving application; and outputting the target measurement signal to the connected measurement signal receiving application.

[0072] It can be understood that the actual use refers to the use of the target measurement device to pick up the current measurement signal, and the actual use can be to determine the posture of the smart device. The measurement signal receiving application refers to the application used to receive the measurement signal picked up by the target measurement device. Since different measurement signal receiving applications have different formats for the received measurement signals, before outputting the signal, it is necessary to determine whether the format of the filtered current measurement signal is consistent with the signal format of the measurement signal received by the measurement signal receiving application. If so, it is directly output after the connection is established. If not, format conversion is required to obtain the target measurement signal, and then the target measurement signal is output to the connected measurement signal receiving application.

[0073] This embodiment obtains the current noise signal of the heat dissipation device through the target sound pickup device array when it is determined that the target measurement device picks up the current measurement signal; determines the vibration signal mixed in the current measurement signal according to the current noise signal; and filters the vibration signal from the current measurement signal. In the above manner, the current noise signal generated by the heat dissipation device during operation is obtained by using a matrix composed of multiple target sound pickup devices. Since there is a correlation between the vibration signal and the noise signal, the vibration signal mixed in the current measurement signal can be determined by using the vibration signal-noise signal correlation function, and then the vibration signal is filtered out from the current measurement signal, thereby effectively improving the accuracy and efficiency of filtering the vibration signal and avoiding interference with the target measurement device.

[0074] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S20 includes steps S201 to S203:

[0075] Step S201, reading a vibration signal-noise signal correlation function from a target chip.

[0076] It should be noted that the target chip may be a processor chip. The target chip may be a microprocessor unit. The microprocessor unit is a programmable processor unit and program codes may be placed in it. The model of the microprocessor unit may be Samsung Exynos 4412.

[0077] It should be understood that after determining the current noise signal generated when the heat dissipation device is running, the vibration signal-noise signal correlation function is read from the target chip, and the vibration signal-noise signal correlation function records the correlation between the vibration signal and the noise signal. It should also be emphasized that the vibration signal-noise signal correlation function can be generated by collecting the noise signal and the vibration signal in advance, and analyzing and recording the correlation between the noise signal and the vibration signal.

[0078] Step S202: determining a current vibration signal corresponding to the current noise signal according to the vibration signal-noise signal correlation function.

[0079] It can be understood that after reading the vibration signal-noise signal correlation function, the vibration signal-noise signal correlation function is used to infer the current vibration signal corresponding to the current noise signal. The current vibration signal refers to the vibration signal generated at the same time as the noise signal is generated during the operation of the heat dissipation device.

[0080] Step S203: when it is determined that the operation of the heat dissipation device affects the target measurement device, the current vibration signal is used as a vibration signal mixed into the current measurement signal.

[0081] It should be understood that when it is determined that the operation of the heat dissipation device affects the target measurement device, it indicates that the vibration signal interferes with the target measurement device. At this time, the current vibration signal of the heat dissipation device is determined to be the vibration signal mixed in the current measurement signal.

[0082] This embodiment reads a vibration signal-noise signal correlation function from a target chip; determines a current vibration signal corresponding to the current noise signal according to the vibration signal-noise signal correlation function; and when determining that the operation of a heat dissipation device affects a target measurement device, uses the current vibration signal as a vibration signal mixed into a current measurement signal; in the above manner, after obtaining the current noise signal of the heat dissipation device, reads a vibration signal-noise signal correlation function from the target chip, then uses the correlation function to infer the current vibration signal, and determines whether the operation of the heat dissipation device affects the target measurement device; if so, determines that the current vibration signal is a vibration signal mixed into the current measurement signal, thereby effectively improving the accuracy of determining the mixed vibration signal.

[0083] For example, in order to help understand the implementation process of the vibration signal filtering method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 4 , Figure 4 A brief flow chart of a vibration signal filtering method is provided, specifically:

[0084] Take two target sound pickup devices as an example for explanation, namely target sound pickup device 1 and target sound pickup device 2. At this time, target sound pickup device 1 and target sound pickup device 2 form a beam, and then use the beam and the direction of the beam to determine the current noise signal generated when the heat dissipation device is running, and then read the vibration signal-noise signal correlation function from the target chip, and use the vibration signal-noise signal correlation function to determine the current vibration signal corresponding to the current noise signal. When it is determined that the operation of the heat dissipation device affects the target measurement device, the current vibration signal is used as the vibration signal mixed in the current measurement signal, and then the vibration signal is filtered out from the current measurement signal picked up by the target measurement device by using the target filtering device, and when the format of the current measurement signal after filtering is inconsistent with the signal format, the format conversion is performed to obtain the target measurement signal, and then the target measurement signal is output to the connected measurement signal receiving application. When the format of the current measurement signal after filtering is consistent with the signal format, it is directly output to the connected measurement signal receiving application.

[0085] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vibration signal filtering method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.

[0086] This application also provides a vibration signal filtering device, please refer to Figure 5 , the vibration signal filtering device comprises:

[0088] The determination module 20 is used to determine the vibration signal mixed in the current measurement signal according to the current noise signal.

[0089] The filtering module 30 is used to filter the vibration signal from the current measurement signal.

In the above manner, the current noise signal generated by the heat dissipation device during operation is obtained by using a matrix composed of multiple target sound pickup devices. Since there is a correlation between the vibration signal and the noise signal, the vibration signal mixed in the current measurement signal can be determined by using the vibration signal-noise signal correlation function, and then the vibration signal is filtered out from the current measurement signal, thereby effectively improving the accuracy and efficiency of filtering the vibration signal and avoiding interference with the target measurement device.
