Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for adjusting a speed of a fan of a notebook computer according to an embodiment of the present invention, the method including:
step S11: acquiring environmental noise of an area where a target notebook computer is located, and converting the environmental noise into a target electric signal;
step S12: acquiring fan noise of a fan of a target notebook computer in a current running state;
step S13: and adjusting the rotating speed of the fan according to the target electric signal so as to enable the sum of the environmental noise and the fan noise to be within a preset range.
In this embodiment, a method for adjusting a speed of a fan of a notebook computer is provided, by which user experience of people when using the notebook computer can be further improved. Specifically, in the fan speed control method, a BMC (Baseboard Management Controller) is specifically described as an execution main body. Since the BMC control program is easy to modify and adjust, in this embodiment, the BMC is used to adjust the fan speed of the target notebook computer.
It can be understood that, in the process of using the notebook computer, the noise generated by the environmental noise in the area where the notebook computer is located and the fan noise in the notebook computer is generally loud, and affects the use experience of the user. Therefore, in this embodiment, in order to enable people to have a better user experience when using the target notebook computer, the BMC first obtains the environmental noise of the area where the target notebook computer is located. Since the BMC cannot directly identify the environmental noise, after obtaining the environmental noise of the area where the target notebook computer is located, the BMC needs to convert the environmental noise of the area where the target notebook computer is located into an identifiable target electrical signal.
After the BMC converts the environmental noise of the area where the target notebook computer is located into the target electric signal, the fan noise of the fan of the target notebook computer in the current running state is obtained. It is conceivable that the BMC can determine the magnitude of the environmental noise in the area where the target notebook computer is located according to the target electrical signal, and the environmental noise in the area where the target notebook computer is located cannot be adjusted by human power. Therefore, in this embodiment, in order to avoid the influence of the environmental noise of the area where the target notebook computer is located and the fan noise of the target notebook computer on the human health, the BMC adjusts the rotation speed of the fan of the target notebook computer according to the target electrical signal, so that the sum of the environmental noise and the fan noise can be within the preset range.
It is conceivable that if the fan speed of the target notebook computer is higher, the fan generates a relatively large noise; therefore, in this embodiment, the BMC adjusts the fan speed of the target notebook computer to enable the sum of the environmental noise and the fan noise of the area where the target notebook computer is located to be within the preset range, and thereby avoid the adverse effect of the environmental noise and the fan noise of the area where the target notebook computer is located on the human body.
It should be noted that, in this embodiment, the preset range is a noise range set according to the technical specification of the noise level of the computer, wherein specific values of the preset range may also be adaptively adjusted according to the user's own situation, which is not described herein in detail.
Compared with the prior art, the method provided by the embodiment can control the sum of the environmental noise of the area where the target notebook computer is located and the fan noise of the fan of the target notebook computer within the preset range, so that bad feeling brought to a user due to the noise can be avoided, and the user experience of the user when the target notebook computer is used can be further improved.
It can be seen that, in this embodiment, the BMC is first used to obtain the environmental noise of the area where the target notebook computer is located, convert the environmental noise into the target electrical signal, then obtain the fan noise of the fan of the target notebook computer in the current operating state, and finally adjust the rotation speed of the fan according to the target electrical signal, so that the sum of the environmental noise and the fan noise of the area where the target notebook computer is located can be kept within the preset range. Obviously, by the arrangement mode, when people use the notebook computer, harm of environmental noise and fan noise to human bodies is avoided, and therefore user experience of people when the notebook computer is used can be further improved.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the above steps: the process of acquiring the environmental noise of the area where the target notebook computer is located comprises the following steps:
and acquiring the environmental noise of the region where the target notebook computer is located by using a noise monitoring system or a voice recognition system.
It can be understood that, because the noise monitoring system is provided with a computer, a display screen, a sound sensor and system software, in practical application, the BMC can detect the environmental noise of the area where the target notebook computer is located by using the noise monitoring system. Moreover, since the noise monitoring system is already applied in many technical fields, when the noise monitoring system is used to acquire the environmental noise of the area where the target notebook computer is located, the accuracy and reliability of the environmental noise detection result can be relatively improved.
Or, in practical application, the voice recognition system can be used to acquire the environmental noise of the region where the target notebook computer is located. Because a plurality of voice recognition algorithms are integrated in the voice recognition system, the voice recognition system not only can recognize regular natural language, but also can recognize irregular noise, so that when the voice recognition system is used for detecting the environmental noise of the region where the target notebook computer is positioned, the detection method of the environmental noise can be more flexible and diversified.
In a preferred embodiment, the noise monitoring system or the voice recognition system is disposed in the camera of the target notebook computer.
In particular, in practical application, the noise monitoring system or the voice recognition system can be arranged in the camera of the target notebook computer, because the camera of the target notebook computer is usually exposed to the outside of the target notebook computer, therefore, when the noise monitoring system or the voice recognition system is installed in the camera of the target notebook computer, not only can the integration and the installation of a noise monitoring system or a voice recognition system in a target notebook computer be convenient, furthermore, compared to installing a noise monitoring system or a voice recognition system inside the target notebook computer, by the arrangement mode, the noise monitoring system or the voice recognition system can accurately detect the environmental noise of the area where the target notebook computer is located, so that the accuracy of the detection result of the environmental noise of the target notebook computer can be relatively improved.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the above steps: the process of adjusting the rotating speed of the fan according to the target electric signal comprises the following steps:
and based on a PID algorithm, adjusting the rotating speed of the fan according to the target electric signal.
It can be understood that, because the PID (proportional Integral Differential) algorithm not only has the advantages of simple implementation principle, easy implementation, etc., but also can achieve the purpose of accurately regulating and controlling the rotation speed of the target notebook computer fan by using the PID algorithm, in this embodiment, the BMC is based on the PID algorithm and adjusts the rotation speed of the target notebook computer fan according to the target electrical signal.
Obviously, the technical scheme provided by the embodiment can relatively improve the overall reliability of adjusting the rotating speed of the fan of the target notebook computer.
Based on the above embodiment, the present embodiment further describes and optimizes the technical solution, and as a preferred implementation, the method for adjusting the speed of the fan of the notebook computer further includes:
and when the environmental noise is larger than the maximum value of the preset range, prompting early warning information.
In practical application, if the BMC determines that the environmental noise of the area where the target notebook computer is located has exceeded the maximum value of the preset range according to the target electrical signal, it is determined that the environmental noise of the area where the target notebook computer is located has produced harm to human health. At this time, even if the target notebook computer is in a shutdown state, the environmental noise of the area where the target notebook computer is located may also affect the physical health of the user, so in this case, in order to avoid the harm of the environmental noise to the user, the user needs to be prompted with the warning information, so that the user can timely know the current environmental state and take corresponding remedial measures.
Obviously, by the technical scheme provided by the embodiment, not only can the safety of the user when using the target notebook computer be improved, but also the user experience of the user when using the target notebook computer can be further improved.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the above steps: a process for converting ambient noise into a target electrical signal, comprising:
inputting the environmental noise into a target capacitor, and converting the environmental noise into a target electric signal according to the capacitance change of the target capacitor;
wherein, the two ends of the target capacitor are respectively provided with a vibrating diaphragm electrode and a fixed electrode.
In this embodiment, the BMC converts the environmental noise into the target electrical signal by using the target capacitor in the process of converting the environmental noise of the area where the target notebook computer is located into the target electrical signal. Specifically, when the BMC inputs the environmental noise into the target capacitor, the diaphragm electrode in the target capacitor vibrates according to the change of the environmental noise, and thus the capacitance of the target capacitor changes.
Under the working mode of the target capacitor, the BMC can convert the environmental noise of the area where the target notebook computer is located into a corresponding target electric signal according to the capacitance change of the target capacitor. Obviously, the signal conversion method not only has simple working principle, simple and easy operation process, but also has low manufacturing cost, so when the target capacitor is used for converting the environmental noise into the electric signal, the design cost required by the fan speed regulation method provided by the application can be further reduced.
