Description

Technical Field

[0001] The present application relates to the technical field of intelligent devices, and in particular, to a method and device for controlling the fan speed of a device, an electronic device, and a readable storage medium. Background Art

[0002] With the continuous development of intelligent device technology, in order to ensure the user experience, more and more manufacturers choose to equip intelligent devices with higher-performance device hardware during production. Taking smart TVs as an example, under the influence of the iteration of chip manufacturing processes, manufacturers equip high-precision chips for TV motherboards, which also leads to a further increase in the heat dissipation requirements of the device. As a result, active heat dissipation methods such as fan heat dissipation are gradually replacing traditional metal heat dissipation methods. However, the active heat dissipation method has also induced new problems. For example, the noise problem during fan heat dissipation. Currently, in order to balance the heat dissipation of smart TVs and the noise generated during fan rotation, usually, when the user is using the device, the fan speed adjustment system automatically controls the fan speed to increase or decrease at fixed intervals within a certain range according to environmental information such as ambient temperature and ambient noise. However, due to the complex internal structure of smart TVs, the fan speed after automatic control cannot accurately meet the heat dissipation requirements of smart TVs. Therefore, the current control accuracy of the fan speed of smart TVs in the user's usage state is low. Summary of the Invention

[0003] The main purpose of the present application is to provide a method and device for controlling the fan speed of a device, an electronic device, and a readable storage medium, aiming to solve the technical problem of low control accuracy of the fan speed of smart TVs in the user's usage state in the prior art.

[0007] Determine whether to control the speed of the target fan according to the current operating loudness and the operating sensitive loudness corresponding to the basic operating speed.

[0008] To achieve the above object, the present application further provides a device for controlling the fan speed of a device, and the device for controlling the fan speed of a device includes:

Since the operating sensitive loudness can accurately reflect the impact of the internal and external comprehensive noise on the user when the fan performs active heat dissipation, when performing speed control on the target fan, the heat dissipation and the noise generated by the fan rotation can be fully balanced, rather than automatically controlling the fan speed to increase or decrease at fixed intervals within a certain range according to environmental information such as environmental temperature and environmental noise, overcoming the technical defect in the prior art that due to the complex internal structure of the smart TV, the automatically controlled fan speed cannot accurately meet the heat dissipation requirements of the smart TV. Therefore, the control accuracy of the fan speed of the smart device in the user usage state is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Embodiment 1

[0027] First of all, it should be understood that for existing smart devices, with the iterative update of chip manufacturing processes, the control chip needs to dissipate more heat per unit time, that is, the heat dissipation requirements of smart devices are getting higher and higher. At present, due to the limitations of the passive heat dissipation method of traditional metal heat sinks, the active heat dissipation method mainly based on fans has become the mainstream. Taking a smart TV as an example, the main control IC (Integrated Circuit Chip) is the main heat-generating component on the TV motherboard. Usually, a cooling fan is configured for it, and then, according to environmental information such as ambient temperature and ambient noise, the fan speed is automatically controlled to increase and decrease at fixed intervals within a certain range. However, the influencing factors of the fan speed include not only external environmental factors but also the output of its own speaker. Moreover, the increase and decrease at fixed intervals cannot guarantee the real-time and accuracy of the fan speed output. Therefore, there is an urgent need for a method to improve the control accuracy of the fan speed of a smart TV in the user's usage state.

[0028] The embodiment of the present application provides a method for controlling the fan speed of a device. In the first embodiment of the method for controlling the fan speed of a device in the present application, refer to Figure 1 , the method for controlling the fan speed of the device includes:

[0029] Step S10, detecting the real-time operating state of the target device according to the temperature of the main chip of the target device;

[0030] Step S20, if the detected real-time operating state is the user usage state, obtaining the basic operating speed of the target fan corresponding to the target device and the current operating loudness generated by the target fan during operation;

[0031] Step S30, determining whether to control the speed of the target fan according to the current operating loudness and the operating sensitive loudness corresponding to the basic operating speed.

[0032] In this embodiment, it should be noted that the method for controlling the fan speed of the device is applied to a device fan speed control system. The device fan speed control system is set in the target device. The target device is a smart terminal that is equipped with a cooling fan to actively dissipate heat from the main control chip of the target device and has an audio output function by itself. Specifically, it can be a TV set and a computer terminal, etc. The target fan is used to dissipate heat from the main control chip of the target device. The target fan can be specifically built into the target device. The main chip temperature is the real-time temperature of the main control chip of the target device. Specifically, it can be 25°C, 26°C, 27°C, etc. In an implementable manner, assume that the target device is a smart TV, refer to Figure 2 , Figure 2As a partial schematic diagram showing the hardware of an intelligent TV system, the hardware of the intelligent TV system is set on the main PCB (main Printed Circuit Board), specifically including the main IC, a cooling fan, a MIC (Microphone), an SOC (System on Chip), a DDR (display data RAM, double data rate synchronous dynamic random access memory), an EMMC (Embedded Multi Media Card), an AMP (amplifier), a DSP (digital singnal processor), and various power DC-DC converters, etc. Among them, the main IC is the most important heat-generating device on this main board. In addition to the positive and negative poles for power supply, the external interface of the cooling fan also includes a data line for receiving the PWM (Pulse width modulation wave) signal from the main IC to the cooling fan. The rotation speed of the cooling fan is controlled by controlling the duty cycle of the PWM signal. Among them, when the duty cycle is controlled at 100%, the rotation speed of the cooling fan reaches the maximum value at this time. When the PWM signal does not exist, it is equivalent to the signal duty cycle being 0%, that is, the cooling fan is in a non-rotating state. When the duty cycle is controlled between 0% and 100%, the rotation speed of the cooling fan increases linearly with the signal duty cycle. The MIC is used to receive the voice signal of the user. After receiving the voice signal, it needs to be processed by the DSP. The AMP drives the speaker to achieve audio output. In addition, the mainstream digital power amplifier includes a feedback output.

[0033] In addition, it should be noted that the real-time operating state is used to characterize the current operating state of the target device, which may specifically include the user usage state. The user usage state is used to characterize that the user is using the target device, including all application scenarios used by the user. The application scenarios may specifically be that the user switches the program channel and the user searches for the program channel, etc. The basic operating rotation speed is the rotation speed of the fan corresponding to the minimum sound that the user can hear in the user usage state. For example, in an implementable manner, assuming that the intelligent device is an intelligent TV, the distance between the user and the intelligent TV is 2m, and the minimum sound that the user can hear in a quiet environment is 25 decibels, then the basic operating rotation speed is the rotation speed of the fan such that the noise generated by the fan rotation speed is less than 25 decibels when it reaches the user's ear after passing through 2m.

[0034] Additionally, it should be noted that the current operating loudness is used to characterize the sound loudness generated by the target fan when the target fan rotates at the basic operating speed, which can be specifically determined by the basic operating speed. The operating sensitive loudness is used to characterize the maximum sound loudness that cannot be perceived by the user when the target fan rotates at the basic operating speed, which is specifically an exact value that changes in real time. When the combined sound loudness generated by the internal and external environments reaches a certain value when the target fan rotates at a certain rotational speed, the user can receive it. For example, assuming the operating sensitive loudness is H1, when the sound loudness received by the user is greater than H1, the user can perceive abnormal noise from the fan.

[0035] Additionally, it should be noted that the temperature range of the device fan speed control system is T min -T max , where T max is the highest temperature at which the system operates, and T min is the lowest temperature at which the system operates. When the temperature of the device fan speed control system is not within this temperature range, the system cannot operate stably. Furthermore, when the temperature of the device fan speed control system reaches T max or does not reach T min , the main control chip will be set to downclock. For example, in an implementable manner, the temperature range T min -T max of the device fan speed control system can be -50°C - 130°C.

[0036] As an example, steps S10 to S30 include: periodically obtaining the temperature of the main chip of the target device, and based on the temperature of the main chip, detecting the current operating state of the target device, where the period of obtaining can specifically be 1 s, 2 s, 3 s, etc.; if it is detected that the real-time operating state is the user usage state, then obtain the basic operating speed corresponding to the target fan of the target device and the current operating loudness generated by the target fan during operation; based on the current operating loudness and the operating sensitive loudness corresponding to the basic operating speed, determine whether to control the speed of the target fan.

[0037] In an implementable manner, assume that the period for obtaining the temperature of the main chip is the time period Δt from t1 to t2. If the temperature of the main chip is T1 at t1 at this time, and the target device is continuously in the fully loaded user usage state, then based on the current operating loudness and the operating sensitive loudness, determine whether to correspondingly control the speed of the target fan until the temperature of the main chip is read as T2 at a certain Δt, where T2 is the maximum temperature that the device fan speed control can reach when the target device is in the user usage state and the target fan is rotating at full speed.

[0038] In another implementable manner, if it is detected that the real-time operating state is not the user usage state, the device fan speed control system is exited. That is, since the speed of the target fan is controlled by the device fan speed control system only when the real-time operating state of the target device is the user usage state, thereby achieving the purpose of controlling the fan speed of the target fan only in the user usage state. Therefore, it overcomes the technical defect in the prior art of controlling the fan speed of the target fan in any operating state. Therefore, it lays a foundation for improving the control accuracy of the fan speed of the intelligent device in the user usage state.

[0039] Among them, the step of determining whether to control the speed of the target fan according to the current operating loudness and the operating sensitive loudness corresponding to the basic operating speed includes:

[0040] Step A10, obtaining the operating sensitive loudness of the target fan in the user usage state;

[0041] Step A20, determining the environmental comprehensive loudness of the target fan according to the current operating loudness corresponding to the obtained basic operating speed;

[0042] Step A30, determining whether to control the speed of the target fan by detecting the magnitude relationship between the environmental comprehensive loudness and the operating sensitive loudness.

[0043] In this embodiment, it should be noted that when the target device dissipates heat for the main control chip through the target fan, in addition to the external environmental noise and environmental temperature, the internal speaker of the target device also affects the fan speed control. Therefore, when controlling the speed of the target fan, in addition to considering the sound loudness generated when the target fan rotates at the basic operating speed, the sound loudness generated by hardware such as the internal speaker also needs to be considered. Furthermore, it is necessary to combine the sound loudness generated by internal and external environmental influencing factors to determine whether the user can perceive when the target fan rotates at this basic operating speed. Therefore, the environmental comprehensive loudness is used to represent the sound loudness comprehensively generated by the internal and external environments when rotating at the basic operating speed.

[0044] As an example, steps A10 to A30 include: obtaining the operating sensitive loudness of the target fan in the user usage state; obtaining the current operating loudness of the target fan, and determining the environmental comprehensive loudness of the target fan according to the current operating loudness, where the current operating loudness corresponds one-to-one with the basic operating speed; determining whether to control the speed of the target fan by detecting the magnitude relationship between the environmental comprehensive loudness and the operating sensitive loudness.

[0045] Among them, the step of determining whether to control the rotation speed of the target fan by detecting the magnitude relationship between the comprehensive environmental loudness and the operation-sensitive loudness includes:

[0046] Step B10, if it is detected that the comprehensive environmental loudness is less than the operation-sensitive loudness, then do not control the rotation speed of the target fan;

[0047] Step B20, if it is detected that the comprehensive environmental loudness is not less than the operation-sensitive loudness, then obtain the target operation rotation speed corresponding to the operation-sensitive loudness;

[0048] Step B30, adjust the rotation speed of the target fan from the basic operation rotation speed to the target operation rotation speed.

[0049] In this embodiment, it should be noted that the target operation rotation speed is used to represent the fan rotation speed of the target fan controlled by the device fan rotation speed control system, specifically the fan rotation speed that balances the user experience and the heat dissipation requirement. If during the operation of the target fan, the comprehensive environmental loudness generated by the internal and external environments is less than the operation-sensitive loudness, that is, at this time, the user cannot perceive abnormal noises. Therefore, without considering the user's usage experience, the heat dissipation requirement can still be maximally satisfied at the basic operation rotation speed. If the comprehensive environmental loudness generated by the internal and external environments is not less than the operation-sensitive loudness, then it is necessary to balance the user experience and the heat dissipation requirement. Therefore, it is inappropriate to still operate the target fan at the basic operation rotation speed at this time.

[0050] As an example, steps B10 to B30 include: if it is detected that the comprehensive environmental loudness is less than the operation-sensitive loudness, then control the rotation speed of the target fan to be the basic operation rotation speed; if it is detected that the comprehensive environmental loudness is not less than the operation-sensitive loudness, then obtain the target operation rotation speed corresponding to the operation-sensitive loudness; control the rotation speed of the target fan to be replaced from the basic operation rotation speed to the target operation rotation speed.

[0051] Among them, the step of obtaining the operation-sensitive loudness of the target fan in the user usage state includes:

[0052] Step C10, obtain the comprehensive environmental noise of the target fan in the user usage state, perform feature extraction on the comprehensive environmental noise, and obtain the operation-sensitive loudness parameter of the target fan;

[0053] Step C20, according to the preset loudness relationship mapping table, determine the operation-sensitive loudness corresponding to the operation-sensitive loudness parameter.

[0054] In this embodiment, it should be noted that when the real-time state of the target device is the user usage state, the device fan speed control system is entered. Since the running sensitive loudness changes with time, in order to obtain the running sensitive loudness, it is necessary to continuously collect the external environmental noise signal through the MIC, and collect the internal environmental noise signal through the AMP, and then obtain the comprehensive environmental noise through a pre-designed calculation method. Therefore, the comprehensive environmental noise is used to characterize the noise generated by the combination of the internal and external environments of the target fan in the user usage state.

[0055] In addition, it should be noted that the running sensitive loudness parameter is used to characterize the audio parameter of the comprehensive environmental noise, specifically including the comprehensive environmental noise frequency and the comprehensive environmental noise sound pressure. Since different users have different sensitivities to sound, the running sensitive loudness parameter is also an exact value that changes in real time. In an implementable manner, referring to Figure 3 , Figure 3 is a relationship diagram showing the relationship between the running sensitive loudness parameter and the running sensitive loudness. Among them, the "audible threshold" is the lowest audible limit of the pure tone signal at each frequency, and the "loudness level" is used to characterize different levels of running sensitive loudness. The exact running sensitive loudness can be obtained through the running sensitive loudness frequency and the running sensitive loudness sound pressure.

[0056] In another implementable manner, assume that the target device is a smart TV. The smart TV is configured with multiple MICs to collect the external environmental noise signal DATA1. Since the currently commonly used coding methods are PDM mic and I2S mic, the signal format of the collected DATA1 is an I2S signal or a PDM signal. Then, the DATA1 can be decoded and restored to the first original audio W1 through the DSP chip. In addition, since the signal collected by the AMP is usually an I2S signal, it can be simulated as the second original audio signal W2 through the DSP chip. Then, when the sound phases are the same, an algebraic superposition is performed to obtain the comprehensive environmental noise, or the first original audio signal W1 and the second original audio signal W2 can be added, and then the comprehensive environmental noise is obtained through mapping.

[0057] As an example, steps C10 to C20 include: obtaining the external environmental noise signal and the internal environmental noise signal of the target fan in the user usage state, adding the external environmental noise signal and the internal environmental noise signal to obtain a comprehensive environmental noise signal, mapping the comprehensive environmental noise signal to the comprehensive environmental noise; performing feature extraction on the comprehensive environmental noise to obtain the running sensitive loudness parameter of the target fan; using the running sensitive loudness parameter as an index to query a preset loudness relationship mapping table to obtain the running sensitive loudness corresponding to the running sensitive loudness parameter.

[0058] Before the step of determining the comprehensive environmental loudness corresponding to the running sensitive loudness parameter according to the preset loudness relationship mapping table, the device fan speed control method further includes:

[0059] D10. Obtain the test running loudness corresponding to the test running speed of the target fan and the environmental test loudness parameter corresponding to the test running speed;

[0060] D20. Establish a preset loudness relationship mapping table according to the one-to-one correspondence between the test running loudness and the environmental test loudness parameter.

[0061] In this embodiment, it should be noted that the preset loudness relationship mapping table is used to represent the mapping relationship between the running sensitive loudness and the running sensitive loudness parameter in one-to-one correspondence. The test running speed is the fan running speed for testing the preset loudness relationship mapping table before the target device leaves the factory, and specifically can be any value from zero to full speed. The environmental test loudness parameter is used to represent the sensitive loudness parameter corresponding to different test running speeds. For example, assuming that the intelligent device is an intelligent TV, in an implementable manner, assuming that the distance between the user and the intelligent TV in the simulated user usage scenario is 2m, then by integrating all the test running speeds and the sensitive loudness parameters corresponding to each test running speed, the preset loudness relationship mapping table can be obtained.

[0062] As an example, steps D10 to D20 include: obtaining the test running loudness corresponding to the test running speed of the target fan, and obtaining the environmental test loudness frequency and environmental test loudness sound pressure corresponding to the test running speed; establishing a preset loudness relationship mapping table according to the running sensitive loudness jointly corresponding to the test running loudness, the environmental test loudness frequency, and the environmental test loudness sound pressure.

[0063] The embodiment of the present application provides a method for controlling the fan speed of a device. That is, the present application first detects the real-time operating state of the target device according to the temperature of the main chip of the target device, achieving the purpose of accurately reflecting the real-time operating state of the target device through the temperature of the main chip. Furthermore, if the detected real-time operating state is the user usage state, the basic operating speed of the target fan corresponding to the target device and the current operating loudness generated by the target fan during operation are obtained. Then, according to the current operating loudness and the operating sensitive loudness corresponding to the basic operating speed, it is determined whether to control the speed of the target fan, achieving the purpose of controlling the fan speed only for the target device in the user usage state. Since the operating sensitive loudness can accurately reflect the impact of the internal and external comprehensive noise on the user when the fan actively dissipates heat, when controlling the speed of the target fan, it can fully balance the heat dissipation and the noise generated by the fan rotation, rather than automatically controlling the fan speed to increase or decrease at fixed intervals within a certain range according to environmental information such as ambient temperature and ambient noise, overcoming the technical defect that in the prior art, due to the complex internal structure of the smart TV, the fan speed after automatic control cannot accurately meet the heat dissipation requirements of the smart TV. Therefore, the control accuracy of the fan speed of the intelligent device in the user usage state is improved.

[0064] Embodiment 2

[0065] Further, referring to Figure 4 , in another embodiment of the present application, the same or similar content as that in the above Embodiment 1 can be referred to the above description and will not be repeated hereinafter. On this basis, after the step of detecting the real-time operating state of the target device according to the temperature of the main chip of the target device, the method for controlling the fan speed of the device further includes:

[0066] Step E10, if the detected real-time operating state is the heavy load usage state, obtain the speed step value;

[0067] Step E20, according to the speed step value, perform a step adjustment on the basic operating speed of the target fan to obtain the step-adjusted speed.

[0068] In this embodiment, it should be noted that when the real-time operating state of the target device is not the user usage state, there are still some typical real-time operating states, specifically including the heavy-load usage state and the low-power consumption usage state. Among them, the heavy-load usage state is used to represent that the target device is in a system heavy-load application scenario, such as a factory debugging scenario and an extreme temperature measurement scenario, etc. When in the heavy-load usage state, the heat generation of the target device reaches the peak. The low-power consumption usage state is used to represent that the target device is in a low-power consumption application scenario, such as the device being in a standby state, staying on the home page without manual operation, and the device playing a low-frame rate or low-resolution video source, etc. Furthermore, the rotation speed of the target fan can be controlled accordingly according to the operating state.

[0069] In addition, it should be noted that when the real-time operating state of the target device is in the heavy-load usage state, if the target fan is controlled to rotate at the basic operating rotation speed, even if the basic operating rotation speed is T2, it still cannot meet the heat dissipation requirements of the target device. Therefore, the step-adjusted rotation speed is the basic operating rotation speed in the heavy-load usage state after adjusting the step interval. In an implementable manner, assume that the basic operating rotation speed in the heavy-load usage state is S, and the basic operating rotation speed in the user usage state is S1. Then S = S1 + ΔS, where ΔS is used to represent the step value. The step value can specifically be: ΔS = (S2 - S1) / 10, where S2 is the highest rotation speed of the target fan in the user usage state, and S1 is the lowest rotation speed of the target fan in the user usage state.

[0070] As an example, steps E10 to E20 include: if it is detected that the real-time operating state is the heavy-load usage state, obtain the rotation speed step value; calculate the step-adjusted rotation speed according to the pre-designed calculation formula and the rotation speed step value, and use the step-adjusted rotation speed as the basic operating rotation speed of the target fan in the heavy-load usage state.

[0071] Among them, after the step of detecting the real-time operating state of the target device based on the main chip temperature of the target device, the device fan rotation speed control method further includes:

[0072] Step F10, if it is detected that the real-time operating state is the low-power consumption usage state, control the basic operating rotation speed of the target fan to the idle operating rotation speed.

[0073] As an example, step F10 includes: if it is detected that the real-time operating state is the low-power consumption usage state, control the basic operating rotation speed of the target fan to the idle operating rotation speed, where the idle operating rotation speed can be 0.

[0074] The embodiment of the present application provides a method for adjusting the basic operating speed. That is, if the detected real-time operating state is a heavy-load usage state, the speed step value is obtained; if the basic operating speed of the target fan is step-adjusted according to the speed step value, the step-adjusted speed is obtained. Since the heat generation of the target device is different in different real-time operating states, when the real-time operating state of the target device is a heavy-load usage state, the basic operating speed of the target fan is step-adjusted by the speed step value. Therefore, when the heat generation of the target device exceeds the maximum heat generation in the user usage state, the purpose of balancing the control of the speed of the target fan can be achieved. That is, when controlling the target fan, the heat dissipation requirement of the target device can still be met, overcoming the technical defect that only the speed of the target fan in the user usage state can be effectively controlled. Therefore, it lays a foundation for improving the effect of effectively controlling the speed of the target fan.
