fig. 1 is a flowchart of a control method of a notebook computer according to an embodiment of the present invention.
Fig. 2 is a schematic structural diagram of a notebook computer according to an embodiment of the present invention.
Reference numerals:
a notebook computer 100; an air inlet 20; a fan 30.
Detailed Description
Embodiments of the present invention will be described in detail below, and the embodiments described with reference to the drawings are exemplary.
The notebook computer 100 may be provided therein with a fan 30 such as a centrifugal fan, the notebook computer 100 may be formed with an air inlet 20, and for example, the bottom of the notebook computer 100 may be formed with the air inlet 20. If the rotation speed of the fan 30 is constant, when the air inlet 20 is blocked, the amount of air entering the notebook computer 100 changes, and therefore the PWM (Pulse width modulation) value of the fan 30 changes. Therefore, whether the air inlet 20 is blocked or not can be judged by judging the magnitude of the PWM value, and if the air inlet is blocked, the laptop mode can be entered. The laptop mode may include any cases that may cause the air inlet 20 to be blocked, for example, when the user places the notebook computer 100 on the knee, due to the special configuration of the human body, the foot pad of the notebook may hang over the air inlet 20 and get closer to the human body, which may cause the air inlet environment to be blocked. The air inlet 20 of the notebook computer 100 is easily blocked by the knee, and if the air inlet 20 is blocked, the PWM value of the fan 30 will be changed. Of course, in other cases where the air inlet 20 is blocked, the PWM value of the fan 30 will also be reduced.
A control method of the notebook computer 100 according to an embodiment of the present invention is described below with reference to fig. 1 and 2, including the steps of:
s1, acquiring a first initial PWM value of the fan 30 of the notebook computer 100. Comparing the first initial PWM value may facilitate determining whether the air inlet 20 is blocked. The first initial PWM value is obtained when the user of the notebook computer 100 is powered on for the first time or the first few times, and is used as a judgment basis.
And S2, acquiring a first current PWM value of the fan 30 when the fan is currently operated. If the first current PWM value and the first initial PWM value are changed, it may be determined that the air inlet 20 is blocked.
And S3, judging whether the first current PWM value is smaller than the first initial PWM value. Therefore, whether the air inlet 20 is blocked at this time can be determined by determining whether the first current PWM value is smaller than the first initial PWM value. For example, when the user places the notebook computer 100 on the leg, the air inlet 20 is blocked by the leg, which results in insufficient air inlet volume, and the first current PWM value is smaller than the first initial PWM value.
S4, when the judgment result in the step S3 is yes, the laptop mode is entered. That is, when the first current PWM is less than the first initial PWM value, the laptop mode may be entered in order to protect the user's body and hardware of the notebook computer 100.
S5, when the judgment result in the step S3 is no, the fan 30 keeps the current operation state. That is, the first current PWM value is greater than or equal to the first initial PWM value, and at this time, the air inlet 20 is not blocked or the opening area of the air inlet 20 is larger (for example, the bottom of the notebook computer 100 is in the open state), so that the current operation state can be maintained without entering the laptop mode. When the first current PWM value is equal to the first initial PWM value, at this time, the air inlet 20 is not shielded; when the first current PWM value is greater than the first initial PWM value, the opening area of the air inlet becomes larger. Neither of the above situations will enter the laptop mode.
According to the control method of the notebook computer 100 of the embodiment of the invention, whether the first current PWM value is smaller than the initial PWM value or not is judged, if yes, the air outlet can be judged to be blocked, and the PWM value of the fan 30 changes, so that the judgment method is simple, the misjudgment rate is low, and the accuracy is high.
The centrifugal fan 30 works on the principle that air enters the fan 30 from the air inlet 20, the S-shaped blades of the fan 30 rotate around the axis to form extrusion to extrude the air entering the fan 30 from the edges of the blades, and the blades are resisted by air resistance in the rotating process.
If the air inlet 20 is blocked, the rotating speed of the fan 30 at the current gear is fixed because air cannot enter the notebook computer 100, and therefore, when the air inlet 20 is blocked, the resistance of the fan 30 is reduced, and the power consumption is reduced, so that the voltage and the PWM value required for reaching the same rotating speed are reduced.
In some embodiments, the ratio of the first current PWM value to the initial PWM value is b, and b satisfies the relation: b is more than 0 and less than 1. That is, the rotation speed of the fan 30 is fixed, and when the intake port 20 is blocked, the intake air amount becomes small, the resistance of the fan 30 becomes small, and thus the power consumption becomes small, and therefore, the voltage and PWM value required to reach the same rotation speed are reduced. Therefore, if the first current PWM value is smaller than the initial PWM value, that is, it can be determined that the air inlet 20 is blocked, the misjudgment rate of the determination method is small, and the accuracy can be improved.
In some embodiments, step S4 specifically includes:
s41, when the judgment result in the step S3 is yes, judging whether the first current PWM value is within the first PWM value preset range; by this step, a preliminary determination can be made as to whether the first current PWM value has decreased.
And S42, when the judgment result in the step S41 is negative, judging whether the first current PWM value is within a second PWM value preset range, wherein the PWM value in the second PWM value preset range is larger than that in the first PWM value preset range. Through the step, the first current PWM value can be further judged to distinguish whether the first current PWM value is within the preset range of the second PWM value or not, so that the judgment accuracy is improved.
And S43, when the judgment result in the step S42 is yes, the first current PWM value is used as a second initial PWM value. Therefore, in order to improve the accuracy of the determination, the first current PWM value meeting the preset range of the second PWM value may be used as a determination basis, that is, the first current PWM value is a PWM value when the dust is deposited in the air inlet 20 or the dust is deposited in the fan 30, and the PWM value when the dust is deposited in the air inlet 20 or the dust is deposited in the fan 30 is used as a new initial PWM value, that is, the second initial PWM value is compared with the current PWM value for determination, so that the accuracy of the determination may be improved.
S44, when the judgment result in the step S41 is yes, the laptop mode is entered. That is, the first current PWM value is greatly decreased, and thus, it can be determined that the air inlet 20 is blocked, and the laptop mode can be entered.
Therefore, the arrangement can prevent the notebook computer from entering a laptop mode easily because the PWM value cannot reach the value of the initial use already when the air inlet 20 or the fan 30 is accumulated with dust after the notebook computer 100 is used for a long time, and the accuracy of the control method is improved. When the first current PWM value detected many times satisfies the second PWM value preset range of small reduction, it can be determined that the PWM value is not reduced by human body shielding when the notebook computer 100 is used for a long time, but the initial PWM determination value needs to be changed to ensure the accuracy of detection because the notebook computer 100 is used for a long time and the air inlet 20 or the fan 30 is deposited with dust.
In some embodiments, the ratio of the second predetermined range of PWM values to the first initial PWM value is a, a satisfies the relationship: a is between 80 and 95 percent. When the above ratio range is satisfied, the accuracy of judgment can be improved. When the air inlet 20 or the fan 30 is deposited with dust after the notebook computer 100 is used for a long time, the rotational resistance of the fan 30 becomes large, and the PWM value of the fan 30 is slightly decreased. If the obtained first current PWM value is within the preset range of the second PWM value for a long time, it can be determined that dust is accumulated in the air inlet 20 or the fan 30 of the notebook computer 100 at this time, and therefore the second PWM value slightly lower than the PWM value can be used as a basis for determining whether to enter the laptop mode, which can make the accuracy higher. For example, a is 90%.
According to some embodiments of the present invention, after step S43, the method further includes:
s45, acquiring a second current PWM value of the fan 30 when the fan is currently running; that is, after entering the laptop mode, the second current PWM value of the fan 30 during the current operation is continuously obtained for judgment, so as to prevent the air inlet 20 from being blocked, and the notebook computer 100 is still in the laptop mode for a long time, thereby improving the accuracy of the judgment.
S46, judging whether the second current PWM value is smaller than the second PWM value; therefore, whether the second current PWM value is smaller than the second PWM value can be continuously determined, so as to determine whether the air inlet 20 is blocked, thereby preventing the occurrence of misjudgment.
S47, if not, keeping the current running state of the fan unchanged; that is, the second current PWM value is equal to the second initial PWM value, that is, the second current PWM value is greater than or equal to the second initial PWM value, and at this time, the air inlet 20 is not shielded, so that the laptop mode is not entered, and the current operation state of the fan is maintained.
And S48, if yes, entering a laptop mode. That is, the second current PWM value is greatly reduced compared to the second initial PWM value, and thus it can be determined that the air inlet 20 is blocked and enters the laptop mode.
Therefore, the situation that the notebook computer 100 cannot exit after entering the laptop mode can be prevented, which is not favorable for the user to experience the use performance of the notebook computer 100. It should be noted that, when the determination result in the step S3 is negative, after the fan 30 keeps the current operation state unchanged, the steps S2 to S5 are repeated to prevent the situation that the air outlet cannot enter the laptop mode after being blocked. Regardless of whether the notebook computer 100 is in the laptop mode, the notebook computer repeatedly detects the current PWM value and compares the detected current PWM value with the first initial PWM value or the second initial PWM value, so as to change the mode according to the actual situation.
In some embodiments, the first initial PWM value is an average value of the PWM values of the fan 30 when the notebook computer 100 is initially turned on for a plurality of times. For example, the first initial PWM value is an average value of PWM values obtained when the notebook computer 100 is initially powered on for 3 to 5 times, and thus, the accuracy of the first initial PWM value can be improved, and the accuracy of entering the laptop mode can be further improved.
In some embodiments, referring to table 1, the fan 30 may have a plurality of gear positions, the fan 30 having a corresponding first initial PWM value at each gear position. For example, the plurality of gears of the fan 30 may include LV0, LV1, LV2 through LV7, and so on. The notebook computer 100 can acquire corresponding first initial PWM values for a plurality of gears and make a judgment to ensure that the fan 30 can enter the laptop mode when being in each gear, thereby ensuring the service life of the notebook computer 100 and improving the user experience. The rotating speed of the fan 30 in LV1 gear can be 2550 rpm, and the noise value can be 22 decibels.

Meanwhile, the hardware of the notebook computer 100 can be protected, and the service life of the notebook computer 100 can be prolonged.
