Detailed Description
So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
The temperature in the following embodiments refers to a system temperature of the electronic device, and the system temperature includes a Central Processing Unit (CPU) temperature, a Graphics Processing Unit (GPU) temperature, and the like.
Preferably, the temperature of the surface of the housing of the electronic device can be collected by the collector, and the temperature of the surface of the housing is taken as the system temperature.
Example one
Fig. 1 is a schematic flow chart illustrating an implementation process of a control method according to an embodiment of the present invention, and in a preferred embodiment of the present invention, as shown in fig. 1, the control method mainly includes the following steps:
step 101: and acquiring temperature parameters in a preset time period.
Here, the preset time period may be set according to actual conditions, for example, the preset time period may be within 1 minute, or within 10 minutes, and the like.
Wherein the temperature parameter may include a minimum temperature value, a maximum temperature value, and a temperature variation value.
Here, a temperature variation range may be determined according to a minimum temperature value and a maximum temperature value, wherein the temperature variation range is a scalar quantity; that is, when determining the temperature variation range, only the minimum temperature value and the maximum temperature value need to be determined, and the trend of the temperature variation (whether to increase or decrease) is not required.
Specifically, the temperature change value may be determined according to a minimum temperature value and a maximum temperature value.
Preferably, the temperature variation value can also be determined by combining the time corresponding to the minimum temperature value and the time corresponding to the maximum temperature value.
That is, the temperature change value is a vector including both the temperature change range and the trend of temperature change.
For example, the minimum temperature value is 40 ℃, and the corresponding time is 8 points, 01 minutes and 01 seconds; the maximum temperature value is 60 ℃, the corresponding time is 01 minutes and 11 seconds at 08 points, the temperature change value is [40,60], and the temperature is in an ascending state, namely the temperature changes from low to high. Similarly, if the minimum temperature value is 40 ℃, the corresponding time is 8 points, 01 minutes and 11 seconds; the maximum temperature value is 60 ℃, the corresponding time is 01 min 01 s at 08 o' clock, the temperature change value is [60,40], and the temperature is in a descending state, namely the temperature changes from high to low.
Step 102: and when the temperature parameter meets a preset condition, determining and adjusting a slope value and a target rotating speed value of the rotating speed of the fan according to the temperature parameter.
That is, only when a preset condition is satisfied, the fan needs to be started to dissipate heat; alternatively, the slope value and the target rotation speed value may need to be re-determined only when a preset condition is satisfied.
Here, the preset condition may be:
the minimum temperature value exceeds a first threshold;
or the maximum temperature value exceeds a second threshold value;
or the minimum temperature value exceeds a first threshold value, and the maximum temperature value is lower than a second threshold value;
alternatively, the minimum temperature value and the maximum temperature value both exceed a second threshold value, and so on.
Here, the first threshold value and the second threshold value may be set according to actual conditions.
For example, the first threshold value is 40 ℃ and the second threshold value is 55 ℃.
For example, when the minimum temperature is greater than 40 ℃, or when the maximum temperature value is greater than 55 ℃, or the minimum temperature is greater than 40 ℃ and the maximum temperature value is less than 55 ℃; or the minimum temperature is more than 40 ℃ and the maximum temperature value is more than 55 ℃; or when the minimum temperature and the maximum temperature are both greater than 55 ℃, the preset conditions are met.
It should be noted that the preset condition may be set according to an actual situation, but is not limited to the above listed situations, and is not described herein again.
Preferably, the target rotation speed value may be determined according to a preset fan control setting table.
Specifically, the determining a target rotation speed value for adjusting the fan rotation speed according to the temperature parameter may include:
determining a temperature variation range based on a minimum temperature value and a maximum temperature value in the temperature parameters;
and searching a target rotating speed value corresponding to the temperature change range from the fan control setting table.
Preferably, the slope value may be determined according to a preset adjustment reference curve.
Wherein, corresponding to each adjusting mode, two groups of adjusting reference curves are respectively called a first adjusting reference curve and a second adjusting reference curve; the first adjusting reference curve is an acceleration curve, and the second adjusting reference curve is a deceleration curve.
It should be noted that the rising speed regulation curve is a regulation reference curve when the system temperature rises from low; the deceleration curve is an adjusting reference curve when the system temperature changes from high to low.
Preferably, when the adjusting mode is a first sub-adjusting mode in a custom adjusting mode, the determining a slope value for adjusting the rotation speed of the fan according to the temperature parameter may include:
determining an adjustment reference curve corresponding to the first adjustment sub-mode based on the temperature change value;
determining a slope value for adjusting the rotation speed of the fan based on the minimum temperature value and the maximum temperature value in combination with the adjustment reference curve;
the slope values at least comprise M slope values, wherein M is a positive integer, and the M slope values correspond to M temperature intervals, and the M temperature intervals form a continuous temperature interval.
Here, the first sub-adjustment mode may be a racing mode, a top speed mode, or the like.
It should be noted that there are several slope values, which need to be determined in combination with the determined adjustment reference curve and the temperature variation range.
Preferably, the determining of the adjustment reference curve corresponding to the first adjustment sub-mode based on the temperature change value may include:
judging whether the temperature change value is a positive number, if so, searching a first regulation reference curve corresponding to the first regulation sub-mode; if not, searching a second adjusting reference curve corresponding to the first adjusting sub-mode.
Because the adjusting slopes of the fans are different under different sub-adjusting modes, the fans can present different adjusting slopes
For example, when the first adjustment sub-mode is a racing mode, the fan speed is adjusted by changing the slope once or more times, so that the fan speed is accelerated or decelerated, and then the sound similar to a real-life racing car is presented (when the system temperature changes from low to high, the sound effect similar to racing car acceleration is presented, and when the system temperature changes from high to low, the sound effect similar to racing car deceleration is presented), so that a user can better feel the change situation of the load of the current electronic equipment.
Step 103: and adjusting the rotating speed of the fan based on the slope value so as to enable the rotating speed of the fan to reach the target rotating speed value.
Preferably, when the adjusting mode is the first adjusting sub-mode, the adjusting the rotation speed of the fan based on the slope value so that the rotation speed of the fan reaches the target rotation speed value may include:
determining a current fan rotating speed value;
and regulating the rotating speed of the fan in the M temperature intervals according to the slope values corresponding to the M temperature intervals by taking the current rotating speed value of the fan as a reference rotating speed value.
Preferably, when the regulation mode is a standard regulation mode, the regulating the rotation speed of the fan based on the slope value so that the rotation speed of the fan reaches the target rotation speed value may include:
determining a current fan rotating speed value;
and taking the current fan rotating speed value as a reference rotating speed value, and uniformly adjusting the rotating speed of the fan according to the slope value so as to enable the rotating speed of the fan to reach the target rotating speed value.
The technical scheme can be applied to electronic equipment such as mobile phones, flat panels, notebook computers, televisions and the like.
In the embodiment of the invention, the temperature parameter in the preset time period is obtained; when the temperature parameter meets a preset condition, determining and adjusting a slope value and a target rotating speed value of the rotating speed of the fan according to the temperature parameter; adjusting the rotating speed of the fan based on the slope value so that the rotating speed of the fan reaches the target rotating speed value; therefore, different fan control modes can be provided, a user can simply judge the transient change of the load according to the adjustment of the fan, and the use experience of the user is improved.
Example two
Fig. 2 is a schematic diagram of an implementation flow of a control method according to an embodiment of the present invention, and in a preferred embodiment of the present invention, as shown in fig. 2, the control method mainly includes the following steps:
step 201: a fan control setting table and an adjustment reference curve are preset.
The fan control setting table is used for storing the one-to-one corresponding relation between the temperature change range and the target rotating speed value.
In this embodiment, the adjustment modes of the fan include a standard adjustment mode and a custom adjustment mode, where the custom adjustment mode includes N sub-adjustment modes, and N is a positive integer.
Here, the first sub-adjustment mode may be a racing mode, a top speed mode, or the like.
Preferably, the presetting of the adjustment reference curve may include:
setting a first regulation reference curve and a second regulation reference curve corresponding to the N sub-regulation modes respectively, and a first regulation reference curve and a second regulation reference curve corresponding to the standard regulation mode; the first adjusting reference curve is an acceleration curve, and the second adjusting reference curve is a deceleration curve.
It should be noted that the rising speed regulation curve is a regulation reference curve when the system temperature rises from low; the deceleration curve is an adjusting reference curve when the system temperature changes from high to low.
For example, the fan control setting table may be as shown in table 1.
TABLE 1
As shown in the above table, TD 0-TD 6 represent temperature reference points at the time of deceleration; TU 0-TU 6 represent temperature reference points at ramp-up; when the temperature is [0, 55], the duty ratio of Pulse-Width Modulation (PWM) is 0X00, and the rotating speed of the fan is 0; when the temperature is [55, 60], the PWM duty ratio is 0XDB, and the rotating speed of the fan is 3800; when the temperature is 60, 65], the PWM duty ratio is 0XE3, and the rotating speed of the fan is 4000; when the temperature is [65, 70], the PWM duty ratio is 0XE7, and the rotation speed of the fan is 4200; when the temperature is [70, 75], the PWM duty ratio is 0XE9, and the rotating speed of the fan is 4600; when the temperature is [75, 80], the PWM duty ratio is 0XEC, and the rotating speed of the fan is 4800; when the temperature is [80, NA ], the PWM duty ratio is 0XF0, and the rotating speed of the fan is 5200; wherein the unit of the Rotation speed is Revolutions Per Minute (RPM).
Note that, in order to prevent the fan from frequently ascending and descending, both the ascending speed and the descending speed have a certain buffer interval. As can be seen from table 1, the temperature reference range for the deceleration rate and the acceleration rate are different.
It should be noted that table 1 is only a one-to-one correspondence relationship between a preferred temperature, a preferred rotation speed, and a preferred PWM duty ratio. In practical applications, the method is not limited to the correspondence between the sets listed in table 1, and will not be described herein again.
Fig. 3 is a schematic diagram illustrating an increasing speed curve for adjusting the rotating speed of a fan, where in fig. 3, a is an increasing speed adjusting curve for adjusting the rotating speed of a fan in the prior art, and b is an increasing speed adjusting curve for adjusting the rotating speed of a fan according to the present invention.
Specifically, for curve a, when the temperature is [ T1, T2], the curve of the speed regulation is a constant slope with a slope value of (F2-F1)/(T2-T1), where F2 represents the PWM duty at the temperature of T2 and F1 represents the PWM duty at the temperature of T1.
Specifically, for curve b, when the temperature is [ T1, T3], the curve of the speed regulation is a non-constant slope with a slope value of (F3-F1)/(T3-T1), wherein F1 represents the PWM duty cycle at the temperature of T1, and F3 represents the PWM duty cycle at the temperature of T3; when the temperature is [ T3, T4], the slope value is (F4-F3)/(T4-T3), wherein F4 represents the PWM duty cycle when the temperature is T4; when the temperature is [ T4, T5], the slope value is (F5-F4)/(T5-T4), wherein F5 represents the PWM duty cycle when the temperature is T5; when the temperature is [ T5, T6], the slope value is (F6-F5)/(T6-T5), wherein F6 represents the PWM duty cycle when the temperature is T6; when the temperature is [ T6, T7], the slope value is (F7-F6)/(T7-T6), wherein F7 represents the PWM duty cycle when the temperature is T7; when the temperature is [ T7, T2], the slope value is 0, wherein the PWM duty ratio when the temperature is T2 is F2;
preferably, the PWM duty cycles are all F2 when the temperatures are T3, T5, T7, i.e. the same as the PWM duty cycles when the temperature is T2.
It will be appreciated that the corresponding slope value is selected according to the range of temperature change. And in the interval needing the speed increase, determining the maximum value and the minimum value of the new slope curve according to the maximum rotating speed and the rotating speed of the stable speed increase slope. And realizing one or more times of acceleration according to the new slope so as to achieve specific sound effect and improvement of heat dissipation performance.
It should be noted that the speed reduction regulation curve is similar to the speed increase regulation curve, specifically, the speed reduction regulation curve for regulating the fan rotation speed in the prior art is a constant slope, that is, the speed is reduced at a constant speed according to the same slope; the speed reduction regulating curve for regulating the rotating speed of the fan provided by the invention is a non-constant slope, namely, in the speed reduction process, the target rotating speed is achieved by converting the slope once or for many times, and the description is not repeated.
Step 202: and acquiring temperature parameters in a preset time period.
Here, the preset time period may be set according to actual conditions, for example, the preset time period may be within 1 minute, or within 10 minutes, and the like.

Preferably, the temperature variation value can also be determined by combining the time corresponding to the minimum temperature value and the time corresponding to the maximum temperature value.
That is, the temperature change value is a vector including both the temperature change range and the trend of temperature change.
Step 203: and when the temperature parameter meets a preset condition, determining and adjusting a slope value and a target rotating speed value of the rotating speed of the fan according to the temperature parameter.
Here, the preset condition may be:
the minimum temperature value exceeds a first threshold;
or the maximum temperature value exceeds a second threshold value;
or the minimum temperature value exceeds a first threshold value, and the maximum temperature value is lower than a second threshold value;
alternatively, the minimum temperature value and the maximum temperature value both exceed a second threshold value, and so on.
Here, the first threshold value and the second threshold value may be set according to actual conditions.
It should be noted that the preset condition may be set according to an actual situation, but is not limited to the above listed situations, and is not described herein again.

the slope values at least comprise M slope values, wherein M is a positive integer, and the M slope values correspond to M temperature intervals, and the M temperature intervals form a continuous temperature interval.
Here, the first sub-adjustment mode may be a racing mode, a top speed mode, or the like.
It should be noted that there are several slope values, which need to be determined in combination with the determined adjustment reference curve and the temperature variation range.

judging whether the temperature change value is a positive number, if so, searching a first regulation reference curve corresponding to the first regulation sub-mode; if not, searching a second adjusting reference curve corresponding to the first adjusting sub-mode.
Because the adjusting slopes of the fans are different under different sub-adjusting modes, the fans can present different adjusting slopes
For example, when the first adjustment sub-mode is the top speed mode, the fan speed is adjusted by changing the slope once or more times, so that the fan speed is rapidly accelerated or rapidly decelerated, the fan speed can be rapidly increased or decreased, and heat accumulation can be better dealt with.
Step 204: and adjusting the rotating speed of the fan based on the slope value so as to enable the rotating speed of the fan to reach the target rotating speed value.

step 401: setting an adjusting mode of the fan according to the selection of a user; wherein the adjusting mode is a self-defined adjusting mode.
Step 402: and acquiring temperature parameters in a preset time period.
Here, the preset time period may be set according to actual conditions, for example, the preset time period may be within 1 minute, or within 10 minutes, and the like.
Wherein the temperature parameter may include a minimum temperature value, a maximum temperature value, and a temperature variation value.
Here, the temperature variation range may be determined according to a minimum temperature value and a maximum temperature value, wherein the temperature variation range is a scalar quantity.
Preferably, the temperature variation value may be determined according to a minimum temperature value, a maximum temperature value, and a time corresponding to the minimum temperature value and a time corresponding to the maximum temperature value.

Step 403: and when the temperature parameter meets a preset condition, determining and adjusting a slope value and a target rotating speed value of the rotating speed of the fan according to the temperature parameter.
Here, the preset condition may be:
the minimum temperature value exceeds a first threshold;
or the maximum temperature value exceeds a second threshold value;
or the minimum temperature value exceeds a first threshold value, and the maximum temperature value is lower than a second threshold value;
alternatively, the minimum temperature value and the maximum temperature value both exceed a second threshold value, and so on.
Here, the first threshold value and the second threshold value may be set according to actual conditions.
It should be noted that the preset condition may be set according to an actual situation, but is not limited to the above listed situations, and is not described herein again.
Preferably, the target rotation speed value may be determined according to a preset fan control setting table.

and searching a target rotating speed value corresponding to the temperature change range from the fan control setting table.
Preferably, the slope value may be determined according to a preset adjustment reference curve.
Wherein, corresponding to each adjusting mode, two groups of adjusting reference curves are respectively called a first adjusting reference curve and a second adjusting reference curve; the first adjusting reference curve is an acceleration curve, and the second adjusting reference curve is a deceleration curve.
It should be noted that the rising speed regulation curve is a regulation reference curve when the system temperature rises from low; the deceleration curve is an adjusting reference curve when the system temperature changes from high to low.

Because the adjusting slopes of the fans are different under different sub-adjusting modes, the fans can present different adjusting slopes
For example, when the first adjustment sub-mode is a racing mode, the fan speed is adjusted by changing the slope once or more times, so that the fan speed is accelerated or decelerated, and then the sound similar to a real-life racing car is presented (when the system temperature changes from low to high, the sound effect similar to racing car acceleration is presented, and when the system temperature changes from high to low, the sound effect similar to racing car deceleration is presented), so that a user can better feel the change situation of the load of the current electronic equipment.

determining a current fan rotating speed value;
and regulating the rotating speed of the fan in the M temperature intervals according to the slope values corresponding to the M temperature intervals by taking the current rotating speed value of the fan as a reference rotating speed value.
For example, assuming that the adjustment mode of the fan is preset by the user to be a racing mode in the self-defined adjustment mode, when the user plays a game by using the electronic device, the system temperature will be higher, at this time, when the system temperature meets the preset condition, the rotating speed will be adjusted according to the racing mode, and the sound effect of racing can be generated while heat is dissipated.
The technical scheme can be applied to electronic equipment such as mobile phones, flat panels, notebook computers, televisions and the like.
In the embodiment of the invention, if the user selects the self-defined adjusting mode, when the system temperature meets the preset condition, the fan speed is controlled to be increased or decreased according to the slope of the rotating speed of the fan, which is corresponding to the self-defined adjusting mode, so that the rotating speed of the fan is adjusted, and simultaneously, the sound effect corresponding to the self-defined adjusting mode is presented, and the user can sense the transient change of the load according to the sound, thereby greatly improving the user experience.

or the maximum temperature value exceeds a second threshold value;
or the minimum temperature value exceeds a first threshold value, and the maximum temperature value is lower than a second threshold value;
alternatively, the minimum temperature value and the maximum temperature value both exceed a second threshold value, and so on.
Here, the first threshold value and the second threshold value may be set according to actual conditions.
It should be noted that the preset condition may be set according to an actual situation, but is not limited to the above listed situations, and is not described herein again.
Preferably, the target rotation speed value may be determined according to a preset fan control setting table.
Specifically, the determining a target rotation speed value for adjusting the fan rotation speed according to the temperature parameter may include:

determining a current fan rotating speed value;
and taking the current fan rotating speed value as a reference rotating speed value, and uniformly adjusting the rotating speed of the fan according to the slope value so as to enable the rotating speed of the fan to reach the target rotating speed value.
