The electronic device described above with reference to fig. 1A may be configured to implement the following functions:

As shown in fig. 1B, fig. 1B is a schematic flowchart of a temperature control method provided in an embodiment of the present application, and is applied to the electronic device shown in fig. 1A, where the method includes:

step 101, determining a first power consumption corresponding to a target application mode of the electronic device in a first preset time period.

The first preset time period may be set by a user or default, the first preset time period may be 30s, 1min, 10min, 1h, and so on, which is not limited herein, and the target application mode may include at least one of the following: video applications, chat applications, gaming applications, voice applications, shopping applications, camera applications, reading applications, live applications, and the like, without limitation; different applications may correspond to different application modes and may also be understood as application scenarios, for example, a game application may correspond to different game application modes, and since power consumption corresponding to different modes in different application modes may be different, for example, the game application mode performs more data interaction with the server compared to the reading application mode, and various modules in the electronic device operate at a higher speed compared to the reading application mode, then the first power consumption corresponding to the game application scenario in the first preset time period may be larger.

When the target application mode is opened by the foreground of the electronic device, due to the occurrence of situations such as an excessively long opening time or interaction and data update of the target application mode with a server during a working process, various modules (e.g., a Central Processing Unit (CPU)) in the electronic device may operate at a high speed, etc., which increases first power consumption of the electronic device in a first preset time period, and at the same time of increasing the first power consumption, the internal heat of the electronic device is increased, which may cause a temperature rise problem of a temperature at a position of a housing, a processor, a frame, etc., in the electronic device, thereby causing a performance degradation of the electronic device.

In an implementation manner of the present application, determining a first power consumption corresponding to a target application mode of the electronic device in a first preset time period may include the following steps:

acquiring N input parameters corresponding to the electronic equipment, wherein N is an integer greater than 1;

acquiring N power consumption curves corresponding to the N input parameters in the first preset time period, wherein each input parameter corresponds to one power consumption curve;

and determining first power consumption corresponding to the target application mode of the electronic equipment in the first preset time period according to the N power consumption curves.

Wherein, the input parameters may include at least two of the following: the power consumption curve can change according to the length of time, so that the power consumption curve corresponding to each input parameter of the electronic equipment in a first preset time period can be obtained, and the power consumption curve reflects the problem of power consumption to a certain extent.

In an implementation manner of the present application, determining, according to the N power consumption curves, a first power consumption of the electronic device corresponding to the target application mode in the first preset time period may include the following steps:

determining N average power consumption rates of the electronic equipment in the first preset time period according to the N power consumption curves, wherein each power consumption curve corresponds to one average power consumption rate;

determining N average power consumptions corresponding to the N input parameters according to the N average power consumption rates, wherein each power consumption curve corresponds to one average power consumption;

and summing the N average power consumptions to obtain the first power consumption.

In the target application mode, the power consumption rate corresponding to each input parameter is changed in real time within the first preset time period, so that the first power consumption corresponding to the electronic device can be determined according to the average power consumption rate corresponding to the N input parameters.

Specifically, N average power consumption rates corresponding to the target application mode may be determined according to the N power consumption curves, each input parameter corresponds to one average power consumption rate, and the average power consumption corresponding to each input parameter may be determined according to the N average power consumption rates, where the first power consumption represents a power loss corresponding to the N input parameters in a first preset time period, and therefore, the N average power consumptions are summed to obtain the first power consumption corresponding to the target application mode.

Optionally, before the determining of the first power consumption corresponding to the target application mode by the electronic device in the first preset period, the method may further include the following steps:

acquiring N initial power consumptions corresponding to the N input parameters in a second preset time period, wherein the second preset time period is earlier than the first preset time period;

acquiring N weights corresponding to the N input parameters, wherein each input parameter corresponds to one weight, and the sum of the N weights is 1;

determining power consumption evaluation values corresponding to the N input parameters according to the N weights and the N initial power consumptions to obtain N power consumption evaluation values;

selecting at least one power consumption evaluation value corresponding to the power consumption evaluation values exceeding a preset evaluation value from the N power consumption evaluation values;

acquiring at least one input parameter corresponding to the at least one power consumption evaluation value;

adjusting the at least one input parameter to obtain at least one target input parameter after parameter adjustment;

and maintaining the operation of the target application mode based on the at least one target input parameter, and executing the step of determining the first power consumption of the electronic equipment corresponding to the target application mode in a first preset period.

The second preset time period can be set by a user or default by a system, and can be earlier than the first preset time period, for example, the second preset time period can be 10min within the time period of 19: 00-19: 10, and the second preset time period can be 10min within the time period of 19: 10-19: 20; because the electronic device can generate heat continuously during operation, the corresponding power consumption is different in different time periods.

In addition, when the internal power consumption of the electronic equipment is increased, the internal power consumption of the electronic equipment can be reduced by changing the forward input mode of the system corresponding to the whole electronic equipment, namely, the internal power consumption of the electronic equipment is reduced by regulating and controlling the N input parameters in a second preset time period, so that the aim of reducing the temperature rise is fulfilled.

In specific implementation, the electronic device may preset a weight corresponding to each input parameter, where the higher the weight is, the more power consumption generated by the electronic device is, the greater the influence on the problem of temperature rise in the electronic device is, or the greater the weight is, the worse the user experience is, and N initial power consumptions corresponding to the N input parameters within a second preset time period may be obtained for the N input parameters.

Further, since power consumption is varied in real time, the initial power consumption may be different from the first power consumption, and determining power consumption evaluation values corresponding to the N input parameters according to the N weights and the N initial power consumptions to obtain N power consumption evaluation values, the power consumption evaluation value reflects the influence of the input parameters on the power consumption of the electronic equipment in a certain sense, and the larger the power consumption evaluation value is, indicating that the influence thereof on power consumption is larger, that is, indicating that the effect of adjusting the input parameter on reducing initial power consumption is larger, and therefore, at least one power consumption evaluation value corresponding to more than a preset evaluation value may be selected, the preset evaluation value can be set by a user or defaulted by a system, and at least one input parameter corresponding to the power consumption evaluation value is acquired, the at least one target input parameter may be obtained by adjusting the at least one input parameter, and the target input parameter may include at least one of: charging rate, background applications, frame rate, CPU frequency, GPU frequency, screen brightness, system sound, etc., without limitation; the normal work or working state of the target application mode can be maintained or kept through at least one target input parameter, so that the effect of preliminarily reducing the internal power consumption of the electronic equipment is achieved.

As shown in table 1 below, a table of relationships between input parameters and weights, as shown in the table, the input parameters include: the charging rate, the background application, the frame rate, the CPU frequency, the GPU frequency, the screen brightness, the system sound, and the like, different weights may be set for different input parameters, the weights may be set according to user experiences, the larger the weight is, the greater the influence on the user experience is, the larger the power consumption evaluation value is, the greater the influence on the power consumption is, in addition, the table may also include an initial power consumption corresponding to each input parameter, the initial power consumption may refer to an initial power consumption corresponding to each input parameter in a second preset time period, the initial power consumption may be obtained based on parameters such as power consumption and power consumption rate, the power consumption evaluation value corresponding to each input parameter may be determined, for example, if the input parameter corresponding to the power consumption evaluation value exceeding the preset evaluation value is obtained as the screen brightness, the initial power consumption corresponding to the second preset time period inside the electronic device may be reduced by reducing the current screen brightness step by step, the specific regulation and control manner is not limited herein.

And 102, acquiring a current temperature and a preset temperature corresponding to a target position of the electronic equipment.

Wherein, the electronic device may include a temperature sensor, the current temperature of the electronic device at the target position may be obtained by the temperature sensor, the step of obtaining the current temperature and the preset temperature corresponding to the target position of the electronic device may be performed when the first power consumption exceeds a preset threshold, the preset threshold may be set by a user or default, the preset threshold is equivalent to a valve for controlling the electronic device to open a negative feedback mechanism, the first power consumption corresponding to the target application mode of the electronic device changes with time, and as the running time of the target application mode increases, when the first power consumption exceeds the preset threshold, the temperatures corresponding to different components inside the electronic device become higher and higher, therefore, the temperature may be obtained for a certain position inside the electronic device, specifically, the current temperature corresponding to the target position inside the electronic device may be obtained, the target location may include at least one of: the temperature of the housing, the temperature of the screen, the temperature of the bezel, the temperature of the inside of the processor, the temperature of the speaker, the temperature of the power management chip, etc., without limitation.

In addition, different preset temperatures can be set for different internal positions of the electronic device, where the preset temperature may refer to a normal temperature corresponding to an internal position of the electronic device when the electronic device normally operates, or a temperature when the preset temperature is a temperature corresponding to a target position so that a system corresponding to the electronic device reaches a stable state of power consumption output.

And 103, determining a target temperature difference function corresponding to the target position according to the current temperature and the preset temperature.

The current temperature can change along with the change of time, so different target temperature difference functions can be set for different current temperatures and preset temperatures, the target temperature difference functions can be set by users or defaulted by a system, the target temperature difference functions represent the change relation between the temperature and the time, and are functions related to the time.

Optionally, determining a target temperature difference function corresponding to the target position according to the current temperature and the preset temperature may include the following steps:

determining a temperature difference corresponding to the target position based on the preset temperature and the current temperature;

and determining the target temperature difference function e (t) corresponding to the temperature difference according to the mapping relation between the preset temperature difference and the preset temperature difference function, wherein e (t) is a function of the temperature difference with respect to time.

The temperature is changed in real time along with time, so that different temperature difference functions can be preset by the electronic equipment, different preset temperature differences can correspond to different temperature difference functions, and the negative feedback mechanism can be controlled through the temperature difference functions, so that the purpose of cooling is achieved.

And step 104, determining a target PID control parameter corresponding to the target application mode according to a mapping relation between a preset application mode and a preset PID control parameter.

The PID controller (proportional-integral-derivative controller) is a feedback loop component commonly used in industrial control applications, and is composed of a proportional (proportional) unit P, an integral (integral) unit I and a derivative (derivative) unit D, and a negative feedback mechanism corresponding to the electronic device can be realized by the PID controller, and temperature control can be realized by adjusting the temperature based on the negative feedback mechanism through a temperature reduction method.

Further, the PID control parameter may include at least one of: a proportional factor, an integral factor, a differential factor, etc., which are not limited herein; in different applications of electronic equipment such as games, videos, news, cameras, reading and the like, the heating characteristics are different, and if all application scenes use the same PID control parameters, the temperature requirements of all the scenes cannot be met, so that different PID control parameters can be adopted for different scenes, and each application scene can correspond to one group of PID control parameters.

And 105, adjusting the current temperature to the preset temperature based on the target PID control parameter and the target temperature difference function, so that the first power consumption of the electronic equipment is adjusted to be second power consumption.

After determining the PID control parameter corresponding to the target application mode, the current temperature may be controlled to the preset temperature by the target temperature difference function within a certain period of time, so as to minimize the temperature difference between the current temperature and the preset temperature, thereby reducing the temperature rise of the electronic device.

In an implementation manner of the present application, adjusting the current temperature to the preset temperature based on the target PID control parameter and the target temperature difference function, so that the first power consumption of the electronic device is adjusted to the second power consumption, may include the following steps:

determining the adjustment range of the second power consumption as the first power consumption of the electronic equipment in the first preset time period

Wherein, P_iThe average power consumption corresponding to any one input parameter is obtained;

acquiring a preset PID control formula:

wherein, K_p、K_iAnd K_dRespectively representing a proportional parameter, an integral parameter and a differential parameter, P (t) is

Any one of the values;

adjusting the first power consumption of the electronic device to the second power consumption by adjusting the proportional parameter, the integral parameter, and the derivative parameter based on the PID control formula and the target temperature difference function e (t).

Wherein, the PID control formula can be set by the user or defaulted by the system, and the PID control formula can be set by the user or the system

The integrator is used for summing the average powers corresponding to all input parameters, which can be understood as parameters affecting the power consumption during the operation of the electronic device

Differentiator

And a proportioner K_pe (t) are all functions related to a target temperature difference function, the proportional parameter represents the proportional relation between input power consumption and output power consumption, the sensitivity of the whole temperature control method can be adjusted by adjusting the parameter, an error in a past period is introduced into an integral parameter, the stable speed of a system corresponding to the whole temperature control method corresponding to the electronic equipment can be accelerated, a steady-state error can be eliminated, and a differential parameter mainly relates to a variation trend, so that the error can be eliminated as soon as possible.

In addition, since the actual heating conditions corresponding to different application scenarios are different, for example, the power consumption corresponding to the video application is relatively larger than that of the reading application, and therefore, the target proportional parameter, the target integral parameter, and the target differential parameter corresponding to the target application mode can be obtained for the target application mode.

Further, since the target temperature difference function is also changed from time to time, the first power can be adjusted based on the target temperature difference function by adjusting the target proportional parameter, the target integral parameter and the target differential parameter, and by the above formula

The internal switching minimizes the temperature difference between the preset temperature and the current temperature corresponding to the target position in the electronic device, and even approaches 0, which is the second power consumption in the second power consumption range

Therefore, the power can be adjusted by adjusting the PID parameters in a targeted manner, so that the temperature in the electronic equipment is reduced.

Optionally, after the adjusting the current temperature to the preset temperature based on the target PID control parameter and the target temperature difference function so that the first power consumption of the electronic device is adjusted to a second power consumption, the method further includes:

determining a temperature difference between the current temperature and the preset temperature;

when the temperature difference approaches zero and the second power is greater than

Setting the value corresponding to the P (t) to be a preset value, and resetting the target temperature difference function e (t).

If the electronic device is in an extreme environment, for example, the external environment is high in temperature, during the process of adjusting the PID control parameter, the electronic device may overshoot, and when the electronic device controls the PID control parameter, the temperature corresponding to the target position of the electronic device has reached the preset temperature, and when the temperature difference has reached the requirement, the second power output by the system far exceeds the maximum value

Starting from the adjustment of the PID control parameter, at this time, the system inside the electronic device is in an unstable state, or the system cannot reach a stable state in time after the recovery of the subsequent external influence factor due to the long-time accumulation of the integral parameter, so to avoid the above situation, a preset value is set for the output second power, that is, P (t), and if the above situation occurs, P (t) can be set) The value of (a) is set as a preset value, and the value corresponding to the target temperature difference function e (t) is reset at this time, so as to avoid the occurrence of overshoot, which is a quantity for measuring the adjustment quality, and it can be understood that, when the system reaches a steady state, the control action is too large, so that the output of the system exceeds the steady state value, therefore, the above method can be adopted to promote the system to return to an initial state within a short time, or expect the stable state to return, so as to enable the system corresponding to the electronic device to reach a stable state.

As shown in fig. 5, fig. 5 is a schematic flowchart of a temperature control method provided in an embodiment of the present application, and is applied to the electronic device shown in fig. 1A, where the method includes:

step 501, determining a target application mode corresponding to the electronic device.

Wherein, the application mode may include at least one of the following: a game application mode, a reading application mode, a video application mode, a voice application mode, etc., which are not limited herein; each application mode may correspond to an application scenario, and in different application modes, due to an excessively long opening time or occurrence of situations such as interaction between the electronic device and a server and data update during a working process of the target application mode, various modules (e.g., a Central Processing Unit (CPU)) in the electronic device may operate at a high speed, which increases an internal temperature of the electronic device, thereby reducing performance of the electronic device.

Step 502, determining a target temperature control level corresponding to the target application mode according to a mapping relation between a preset application mode and the temperature control level.

The electronic equipment can preset different temperature control levels aiming at different application modes in advance, the higher the temperature control level is, the greater the influence of the corresponding application mode on the temperature is, and the target temperature control level corresponding to the target application mode can be determined according to the mapping relation between the preset application mode and the temperature control level.

For example, as shown in table 2 below, the table is a corresponding relationship table between the application modes and the temperature control levels, wherein the temperature control levels can be divided into 3 levels, each level can correspond to a different application mode, and the higher the temperature control level is, the greater the influence of the application mode corresponding to the temperature control level on the temperature is, as shown in the table, the game application mode and the video application mode can be divided into three levels of temperature control levels, the voice application mode can be divided into two levels of temperature control levels, and the reading application mode can be divided into one level of temperature control levels.

TABLE 2 relationship between application modes and temperature control levels

Step 503, obtaining a current temperature corresponding to the target position of the electronic device.

Wherein the target position may include at least one of: the temperature of the housing, the temperature of the screen, the temperature of the bezel, the temperature of the inside of the processor, the temperature of the speaker, the temperature of the power management chip, etc., without limitation.

Step 504, based on the target temperature control level, adjusting the current temperature corresponding to the target position to a preset temperature.

The preset temperature is generally lower than the current temperature, and the preset temperature can be set by a user or defaulted by a system, in addition, the preset temperature can also be a temperature interval, and the current temperature can be adjusted to any value in the temperature interval within a certain period of time.

Optionally, in the step 504, based on the target temperature control level, adjusting the current temperature corresponding to the target position to a preset temperature may include the following steps:

acquiring at least one input parameter corresponding to the target application mode;

determining a weight corresponding to each input parameter in the at least one input parameter based on the target temperature control level to obtain at least one weight, wherein each input parameter corresponds to one weight;

adjusting the current temperature corresponding to the target position to the preset temperature based on the at least one input parameter and the at least one weight.

Wherein, the input parameters may include at least one of the following: charging rate, background application, screen brightness, system sound, mobile phone frame rate, Central Processing Unit (CPU) frequency, Graphics Processing Unit (GPU) frequency, hardware module, etc., which are not limited herein, the input parameters may be understood as the parameters during the operation of the electronic device, some parameters influencing the temperature also influence the power consumption corresponding to the electronic equipment when the temperature rises, the electronic equipment reduces the temperature by adjusting the input parameters, specifically, the electronic equipment can preset the weight corresponding to each input parameter aiming at different temperature control levels, the higher the weight is, the greater the influence of the weight on the temperature is, wherein each temperature control level corresponds to a set of input parameters, each input parameter corresponds to a weight, the input parameters can be adjusted and controlled in a targeted manner to achieve the effect of cooling, so that the temperature control efficiency can be improved.

In addition, different PID control parameters may be set for different temperature control levels, and the PID control parameters may include at least one of: a proportional factor, an integral factor, a differential factor, etc., which are not limited herein; the application scene modes corresponding to different temperature control levels are different, the heating characteristics of the electronic equipment in different application modes such as games, videos, news, cameras and reading are different, and if all application scenes use the same PID control parameters, the temperature requirements of all the scenes cannot be met, so that different PID control parameters can be adopted for different temperature control levels, and each temperature control level can correspond to one group of PID control parameters.

For example, as shown in table 3, a mapping relationship between the temperature control level and the weight corresponding to the input parameter is shown, if the input parameter includes at least one of the following: the charging rate, the screen brightness and the central processor frequency can be weighted according to the three input parameters corresponding to each temperature control level, the larger the weight is, the larger the influence of the weight on the temperature is, wherein the sum of the weights corresponding to at least one input parameter corresponding to each temperature control level is 1, and therefore, the target position of the electronic device can be cooled by regulating and controlling different input parameters, for example, if the target application mode corresponds to a game application mode, the corresponding temperature control level is three, the weight corresponding to the input parameter corresponding to the temperature control level of three can be obtained, as can be known from the table, the proportion of the central processing unit frequency is the largest, the frequency of the central processing unit can be mainly regulated, and two input parameters, namely the charging rate and the screen brightness, can be regulated in an auxiliary mode, so that the temperature of the electronic equipment aiming at the target position is regulated to be the preset temperature from the current temperature.

The detailed description of step 604 and step 605 may refer to the response step of the temperature control method described in fig. 5, and will not be described herein again.

Step 606, adjusting the current temperature to the preset temperature based on the target PID control parameter, the at least one input parameter and the at least one weight, so as to adjust the first power consumption of the electronic device to a second power consumption.

The power consumption problem of the electronic device is more and more concerned with the continuous improvement of the performance requirement of the electronic device, and the increase of the internal temperature of the electronic device can cause the increase of the internal power consumption of the electronic device, so the power consumption can be reduced by reducing the temperature.
