Referring to fig. 1, a flowchart of a method for controlling a terminal temperature according to an exemplary embodiment of the present application is shown, where the method includes:
and step 101, collecting operation data of the terminal in the charging process.
The operation data are used for indicating the use condition of the terminal in the charging process. The user can still use the terminal when the terminal is charged, or can not use the terminal when the terminal is charged; that is, the terminal is charged to include two use states, i.e., an in-use state and an unused state. The in-use state indicates that the terminal is in a state of being operated by a user during charging; the unused state indicates that the terminal is in a state of not being operated by the user during the charging process.
In the charging process, the terminal collects operation data of the terminal to determine the use condition of the terminal. Optionally, the above operation data refers to data generated during program operation in the terminal during the terminal charging process, for example, the number of background processes that the terminal operates, the operation power of the application program, the operation time of the application program, the historical charging time of the terminal, and the charging power.
And 102, determining the use condition of the terminal according to the operation data.
The terminal generates heat in the charging process, and the terminal is used by a user in the charging process, and because the terminal generates heat due to the operation of an application program, the phenomenon of heat superposition can occur, so that the heat generation speed is accelerated, and therefore, the terminal judges the use condition of the terminal according to the operation data of the terminal, and the temperature of the terminal is controlled by adopting different strategies under different use conditions; executing step 103 when the use condition of the terminal is in the use state; when the usage status of the terminal is in an unused state, step 104 is performed.
Optionally, the terminal performs feature learning on the use condition of the terminal according to the operation data in the charging process of the terminal, and predicts the use condition of the terminal in different time periods.
Illustratively, the terminal performs charging feature learning on operation data in the charging process of the terminal through a feature learning algorithm, and predicts the use condition of the terminal in different time periods. The feature learning algorithm may include at least one of a decision tree algorithm, a vector machine, and a neural network algorithm.
Optionally, the operation data of the terminal during charging includes a characteristic value, and the characteristic value can be used for determining the use condition of the terminal. And the terminal determines the use condition of the terminal according to the characteristic value. Optionally, the characteristic value includes at least one of a screen brightness value at the time of terminal charging, interface operation data at the time of terminal charging, and posture data at the time of terminal charging.
And step 103, when the use condition of the terminal is in a use state, adjusting the operation parameters of the terminal in the charging process according to the first temperature threshold value.
A temperature sensor is arranged in the terminal and is used for measuring the body temperature of the terminal; when the using state of the terminal is in the using state, the terminal controls the temperature of the terminal by adopting a first temperature threshold value; when the body temperature of the terminal is greater than or equal to a first temperature threshold, the terminal adjusts the operation parameters of the terminal in the charging process, so that the temperature rising capability of the terminal is reduced; when the body temperature of the terminal is smaller than the first temperature threshold, the terminal still keeps the current operation parameters to operate, and the temperature rising capability of the terminal is unchanged.
Optionally, the above-mentioned operating parameters include at least one of a charging current, a charging voltage, a charging power, and a number of background processes.
The terminal can reduce the temperature rising capability of the terminal by reducing the charging current of the terminal, reducing the charging voltage of the terminal, reducing the charging power of the terminal, or reducing the number of background processes.
And 104, when the use condition of the terminal is in an unused state, adjusting the operation parameters of the terminal in the charging process according to the second temperature threshold.
Wherein the first temperature threshold is less than the second temperature threshold. When the using state of the terminal is in an unused state, the terminal controls the temperature of the terminal by adopting a second temperature threshold value; when the body temperature of the terminal is greater than or equal to the second temperature threshold, the terminal adjusts the operation parameters of the terminal in the charging process, so that the temperature rising capability of the terminal is reduced; when the body temperature of the terminal is smaller than the second temperature threshold, the terminal still keeps the current operation parameters to operate, and the temperature rising capability of the terminal is unchanged.
It should be noted that, in general, the heating capacity of the terminal in the in-use state is greater than the heating capacity of the terminal in the unused state, so the setting of the second temperature threshold may be smaller than the first temperature threshold when the terminal is in the unused state; second, the adjustment amplitude of the operation parameter when the terminal is in the unused state may be smaller than the adjustment amplitude of the operation parameter when the terminal is in the in-use state.
Illustratively, the terminal reduces the heating capacity of the terminal by adjusting the charging power of the terminal. The terminal is provided with a first charging power and a second charging power, and the first charging power is smaller than the second charging power; when the body temperature of the terminal is greater than or equal to a temperature threshold (a first temperature threshold or a second temperature threshold), the terminal is charged by adopting first charging power; and when the body temperature of the terminal is smaller than the temperature threshold value, the terminal is charged by adopting the second charging power.
Alternatively, the first/second charging power may be default in the terminal, or preset in the terminal, or user-defined.
In addition, the process of reducing the temperature raising capability of the terminal by the charging current or the charging voltage is referred to the above illustrative example, and will not be described herein.
Furthermore, the terminal can also reduce the temperature rising capability of the terminal by adjusting the number of background processes of the terminal. The terminal is provided with a background process quantity threshold value; when the body temperature of the terminal is greater than or equal to a temperature threshold (a first temperature threshold or a second temperature threshold), the terminal judges whether the background process number is greater than the background process number threshold. When the number of the background processes of the terminal is larger than the threshold value of the number of the background processes, the terminal ends part of the background processes; when the number of the background processes of the terminal is smaller than or equal to the threshold value of the number of the background processes, the number of the current background processes in the terminal is still kept unchanged. When the number of the background processes of the terminal is smaller than or equal to the threshold value of the number of the background processes, the number of the current background processes in the terminal is still kept unchanged. Optionally, the terminal ends part of the background process according to the order of the service priority of the background process from low to high. The background process of the terminal is the background process in an idle state, and the background process of the terminal is not affected by the application program operated by the foreground of the terminal.
In summary, in the method for controlling the terminal temperature provided in the embodiment, the operation data of the terminal in the charging process is collected; determining the use condition of the terminal according to the operation data; when the using state of the terminal is in the using state, adjusting the operation parameters of the terminal in the charging process according to the first temperature threshold value; when the using state of the terminal is in an unused state, adjusting the operation parameters of the terminal in the charging process according to the second temperature threshold; wherein the first temperature threshold is less than the second temperature threshold.
According to the method, whether the terminal is operated by a user in the charging process is determined by determining the using condition of the terminal, if the terminal is operated by the user in the charging process of the terminal, the terminal adopts a first temperature threshold value with smaller value to measure whether the terminal temperature is suitable, so that when the terminal temperature does not reach the upper limit of the acceptance of the user, the operation parameters of the terminal are timely adjusted, the rising of the terminal temperature is controlled, and the terminal temperature is always in the range acceptable by the user.
If the user does not operate the terminal in the process of charging the terminal, the terminal adopts a second temperature threshold with larger value to measure whether the temperature of the terminal is suitable, and the terminal can adjust the operation parameters when the temperature of the terminal is higher relative to the first temperature threshold, that is, the terminal can relax the control of the temperature of the terminal, and the charging speed of the terminal is relatively accelerated while the safe charging is ensured.
In summary, the method controls the temperature of the terminal through the setting of the temperature threshold value, so that the temperature of the terminal is always in a safe range in the charging process, and the potential safety hazard that the heating condition of the terminal seriously damages the health of a user is solved; and in the process of charging the terminal while playing by the user, the temperature threshold is set from the acceptance of the user to the terminal temperature, so that the terminal temperature is always in the acceptable range of the user, and the user experience is improved.
Considering that the terminal temperature of each user is different in acceptance and the influence of the ambient temperature on the user perception, the setting of the first temperature threshold can be dynamically adjusted according to the ambient temperature and the tolerance temperature, so that the requirements of the users are met. Illustratively, based on fig. 1, step 103 is replaced with steps 1031 to 1034, as in fig. 2, which are as follows:
The environment in which the terminal is located may be indoor or outdoor, and thus, the ambient temperature of the environment in which the terminal is located includes an indoor temperature or an outdoor temperature. When the terminal is located outdoors, the terminal acquires weather data including an outdoor temperature. Alternatively, the terminal acquires the outdoor temperature, and the area where the terminal is located can be located by a global positioning system (Global Positioning Syetem, GPS) to acquire weather data of the area at this time, wherein the weather data includes the outdoor temperature.
Illustratively, the weather data may be obtained by the terminal from a weather data platform via an application programming interface (Application Programming Interface, API).
Optionally, an ambient temperature sensor is provided in the terminal. When the terminal is located indoors, the terminal acquires the indoor temperature through an ambient temperature sensor arranged on the terminal. Or the terminal is connected with the intelligent home through Bluetooth, and the intelligent home comprises an ambient temperature sensor; when the terminal is located indoors, the terminal obtains the indoor temperature provided by the smart home.
It should be noted that, in the process of collecting the environmental temperature of the environment where the terminal is located, the terminal first determines the environment where the terminal is located. Because the moving range in the room is limited, and the moving range in the room is wide, the terminal can determine the environment of the terminal through the moving distance of the terminal; optionally, the terminal measures the moving distance of the terminal through a GPS; when the moving distance of the terminal is greater than the distance threshold, the terminal determines that the environment where the terminal is located is outdoor; when the moving distance of the terminal is equal to or smaller than the distance threshold, the terminal determines that the environment where the terminal is located is indoor.
In some embodiments, the terminal may also determine the temperature of the rechargeable battery in the terminal in an unused state as an ambient temperature by measuring the temperature of the rechargeable battery through an internal temperature sensor.
Or the terminal can also fit the temperature measured by the internal temperature sensor to the surface temperature of the terminal, and the surface temperature is determined to be the ambient temperature; the above-mentioned measured temperature is measured by a temperature sensor inside the terminal in an unused state of the terminal.
The withstand temperature is the highest temperature at which the terminal is charged as accepted by the user, and the threshold parameter is a parameter value for determining the first temperature threshold.
It should be noted that, the threshold parameter is a weight corresponding to the ambient temperature, which reflects the influence of the ambient temperature on the tolerance temperature, and the threshold parameter is used for determining the parameter value of the first temperature threshold; the withstand temperature is the highest temperature at which the user accepts the terminal charge. Since the temperature of the terminal perceived by each user is different, the highest temperature acceptable to each user when the terminal is charged is also different, optionally, a setting interface is displayed on the terminal, and a setting control for tolerating the temperature is included on the setting interface; the terminal self-defines the tolerant temperature through the setting control. The setting control can be a temperature bar, the terminal receives dragging operation on the temperature bar, and the tolerant temperature in the terminal is set; the setting control may also be a text box control, and the tolerance temperature input in the text box control is received and set in the terminal.
Alternatively, the withstand temperature is a predefined or default temperature value in the terminal, wherein the predefined or default withstand temperature in the terminal may reflect the definition of the high temperature by most users.
Step 1033, determining a first temperature threshold based on the ambient temperature, the tolerance temperature, and the threshold parameter.
The first temperature threshold is used to determine an operating parameter of the terminal when charged. Optionally, the terminal determines the first temperature threshold during charging, and may subtract the product of the ambient temperature and the threshold parameter from the tolerance temperature to obtain the first temperature threshold, where the expression is as follows:
T 0 ＝T user -a*T env ； (1)
wherein T is 0 For a first temperature threshold, T env At ambient temperature, T user For the tolerance temperature, a is a threshold parameter, and the sign of "corresponds to the multiplication.
The first temperature threshold is in positive correlation with the ambient temperature. It should be noted that, under different environments, the terminal heating condition felt by the user is related to the environmental temperature; for example, in an environment of 20 ℃, if the terminal temperature is 35 ℃, the user perceives the terminal temperature obviously; however, in an environment of 35 degrees celsius, if the terminal temperature is 35 degrees celsius, the user's perception of the terminal temperature is weak relative to the perception in an environment of 20 degrees celsius, i.e., the user's perception of the terminal temperature is not obvious. Thus, when the ambient temperature is higher, the first temperature threshold is also higher. The expression (1) above represents T 0 Is to T user The corrected value is a×T env The method comprises the steps of carrying out a first treatment on the surface of the Wherein the threshold parameter also changes with the change of the ambient temperature, and the threshold parameter has a negative correlation with the ambient temperature.
Schematically, as shown in table one, when the environmental temperature of the environment where the terminal is located is greater than 35 ℃, the terminal determines that the threshold parameter is 0; when the environmental temperature of the environment where the terminal is located is greater than 25 ℃ and less than or equal to 35 ℃, the terminal determines that the threshold parameter is 0.1; when the environmental temperature of the environment where the terminal is located is more than 20 ℃ and less than or equal to 25 ℃, the terminal determines that the threshold parameter is any value between 0.3 and 0.4; when the environmental temperature of the environment where the terminal is located is more than 15 ℃ and less than or equal to 20 ℃, the terminal determines that the threshold parameter is any value between 0.5 and 0.6; when the environmental temperature of the environment where the terminal is located is more than 10 ℃ and less than or equal to 15 ℃, the terminal determines that the threshold parameter is any value between 0.6 and 0.9; when the environmental temperature of the environment where the terminal is located is more than 5 ℃ and less than or equal to 10 ℃, the terminal determines that the threshold parameter is any value between 1.2 and 2. In addition, when the environmental temperature of the environment in which the terminal is located is lower than 5 ℃, the terminal can not use the control method of the terminal temperature.
List one
| Ambient temperature | Threshold parameter |
| Greater than 35 DEG C | 0 |
| Greater than 25 degrees celsius and less than 35 degrees celsius | 0.1 |
| Greater than 20 degrees celsius and less than 25 degrees celsius | 0.3 to 0.4 |
| Greater than 15 degrees celsius and less than 20 degrees celsius | 0.5 to 0.6 |
| Greater than 10 degrees celsius andless than 15 DEG C | 0.6 to 0.9 |
| Greater than 5 degrees celsius and less than 10 degrees celsius | 1.2 or more and 2 or less |
Thus, in step 1032, the terminal obtains the threshold parameter, which may be a corresponding threshold parameter obtained according to the ambient temperature. Assuming that the tolerance temperature set in the terminal is 45 ℃, when the environmental temperature of the environment where the terminal is located is 20 ℃, the corresponding obtained threshold parameter can be 0.5, and the first temperature threshold of the terminal is calculated to be 35 ℃; when the environmental temperature of the environment where the terminal is located is 35 ℃, the corresponding obtained threshold parameter may be 0.1, and the first temperature threshold of the terminal is calculated to be 41.5 ℃.
It should be noted that, when the terminal determines the threshold parameter according to the environmental temperature of the environment in which the terminal is located, step 1031 is performed prior to step 1032.
In step 1034, the operating parameters of the terminal in the charging process are adjusted by taking the first temperature threshold as the upper temperature limit of the terminal in the charging process.
The terminal measures the magnitude relation between the body temperature and the first temperature threshold value, and adjusts the operation parameters of the terminal in the charging process. For example, alternatively, the terminal measures the body temperature of the terminal through a temperature sensor provided in the terminal; when the temperature of the machine body is greater than a first temperature threshold, the control terminal operates by adopting a first operation parameter corresponding to the first temperature threshold in the charging process; when the temperature of the machine body is smaller than the first temperature threshold, the control terminal operates by adopting a second operation parameter corresponding to the first temperature threshold in the charging process; the heating capacity corresponding to the first operation parameter is smaller than that corresponding to the second operation parameter.
In summary, in the method for controlling terminal temperature provided in the embodiment, the first environmental temperature threshold is calculated by acquiring the environmental temperature, the tolerance temperature and the threshold parameter; because the ambient temperature changes, the first temperature threshold value also changes, when the ambient temperature is low, the perception of the user to the high temperature is high, so that the lower the ambient temperature is, the lower the first temperature threshold value is, and the terminal temperature is controlled in a lower range, so that the temperature perceived by the user can be controlled in an acceptable range.
Secondly, as the perception of each user is different, the first temperature threshold value is also changed along with the change of the tolerance temperature, so that the terminal can set the first temperature threshold value according to the tolerance temperature of each user, the requirements of different users are met, and the user experience is improved.
Based on fig. 1, two ways of determining the usage status of the terminal by the terminal are provided in step 102, as follows:
firstly, a terminal predicts the use conditions of the terminal in different time periods, and then determines the use conditions of the terminal during charging according to the obtained prediction results;
second, the terminal obtains a characteristic value indicating the use condition of the terminal, and determines the use condition of the terminal according to the characteristic value.
In some embodiments, the exemplary steps of the terminal determining the usage status of the terminal in the first manner may be as follows:
1) And the terminal predicts the use condition of the terminal in the charging process according to the operation data to obtain a prediction result.
The prediction result is a prediction result of the usage situation of the terminal in different charging periods. Optionally, the terminal performs cluster analysis on the operation data to obtain a prediction result of the use condition of the terminal in different charging periods. For example, the terminal performs cluster analysis on the operation data of the terminal during charging through a decision tree algorithm, a vector machine or a neural network algorithm to obtain a prediction result of the use condition of the terminal in different charging periods.
Optionally, the operation data of the terminal during charging includes a historical charging period of the terminal and a corresponding historical usage period of the terminal; the historical charging period refers to historical data of a period of time when the terminal is in a charging state; the history use period refers to history data of a period in which the terminal is in a use state during a history charging period of the terminal. And the terminal predicts the use condition of the terminal according to the historical charging time period and the historical use time period to obtain a prediction result.
Optionally, the prediction result includes that if the current time of the terminal belongs to a first time period, the use condition of the terminal is in use; if the current time of the terminal belongs to the second time period, the using state of the terminal is an unused state.
The terminal learns the historical charging time period and the historical using time period through a feature learning algorithm, learns the charging habit of a user on the terminal, divides the prediction of the using condition of the terminal according to the time period, for example, charges the terminal during the afternoon of a certain user, starts afternoon at 12 points, finishes afternoon at 12 points 45 minutes, identifies the operating data of the terminal during the charging period through the feature learning algorithm, divides the time period from 12 points to 12 points 50 into two time periods, namely 12 points to 12 points 40 respectively and 12 points 40 to 12 points 50 respectively, and determines the using condition of the terminal corresponding to 12 points 40 to be in an unused state; the 12 point 40 to the 12 point 50 are determined to be in-use states, and the correspondence relationship between the time period and the terminal use condition in the terminal charging state as described above is shown in table two. One usage status of the terminal may correspond to a plurality of time periods, for example, an unused state of the terminal corresponds to 12 points 40 and 19 to 20 points 30 divided into two time periods.
Watch II
2) The terminal determines the current charging period of the terminal, and determines the use condition corresponding to the current charging period in the prediction result as the use condition of the terminal.
Optionally, the current time of the terminal belongs to a first time period, the terminal determines the current charging time period of the terminal as the first time period, and determines the use condition of the terminal as the in-use state; the current time of the terminal belongs to a second time period, the terminal determines that the current charging time period of the terminal is the second time period, and the use condition of the terminal is determined to be an unused state.
For example, correspondingly, the current time of the terminal is 12 points and 10 minutes, and belongs to 12 points to 40 points, and the use condition of the terminal is an unused state; the current time of the terminal is 12 points 15 minutes, and belongs to 12 points 40 minutes to 12 points 50 minutes, so that the use condition of the terminal is in a use state.
In some embodiments, the terminal determines the usage status of the terminal in a second manner, where the feature value may include at least one of a screen brightness value, interface operation data, and gesture data when the terminal is charged, and the usage status determining method corresponding to the feature value is described respectively, and the exemplary steps may be as follows:
1) And the terminal determines the use condition of the terminal according to the characteristic value in the operation data.
The operation data of the terminal includes a characteristic value, and the characteristic value can be used for determining the use condition of the terminal.
In one case, when the terminal is used by a user, the screen is always in a bright screen state; when the terminal is not used by a user, the screen is switched from a bright screen state to a screen-off state, and the screen of the terminal is in the screen-off state, which means that the terminal does not receive the operation of the user on the terminal. Therefore, the terminal can determine the use condition of the screen, the bright screen state or the off screen state of the terminal through the screen brightness value, thereby determining the use condition of the terminal. It should be noted that, in some embodiments, before the terminal turns off the screen, the screen brightness is first darkened, and after a period of time after the screen brightness is darkened, the terminal still does not receive the trigger operation, and then the terminal is controlled to turn off the screen.
Optionally, the characteristic value includes a screen brightness value when the terminal is charged; the terminal determines the service condition of the terminal according to the screen brightness value; when the screen brightness value of the terminal is larger than the brightness threshold value, the terminal determines that the use condition of the terminal in the charging process is in a use state; when the screen brightness value of the terminal is equal to or smaller than the brightness threshold value, the terminal determines that the use condition of the terminal in the charging process is in an unused state. Wherein the luminance threshold is the lowest luminance value when the terminal is used by the user.

In the embodiment shown in fig. 1, when the terminal is in the in-use state, the terminal determines a first temperature threshold in the terminal according to the ambient temperature, the tolerance temperature and the threshold parameters; in other embodiments, the terminal may also determine the first temperature threshold of the terminal by using the operating power of the application in the foreground operating state when the terminal is charged, illustratively, based on fig. 1, step 103 is replaced by steps 1035 to 1036, as shown in fig. 3, and the steps are as follows:
The operation data of the terminal in the charging process comprises the operation power of the application program in the foreground operation state of the terminal in the charging process; the terminal also stores the corresponding relation between the running power of the application program and the first temperature threshold value. Optionally, the terminal determines a range threshold to which the running power of the application program belongs; when the running power of the application program belongs to a first range threshold, determining a first candidate temperature threshold corresponding to the first range threshold as a first temperature threshold when the terminal is charged; when the running power of the application program belongs to a second range threshold, determining a second candidate temperature threshold corresponding to the second range threshold as a first temperature threshold when the terminal is charged; wherein the value in the first range threshold is less than the value in the second range threshold, and the first candidate temperature threshold is different from the second candidate temperature threshold. Optionally, the first candidate temperature threshold is greater than the second candidate temperature threshold.
Schematically, as shown in table three, the correspondence between the operating power of the application program and the first temperature threshold value indicates that when the operating power of the application program belongs to the range threshold value [20W,40W ], that is, is equal to or greater than 20 watts (W) and less than or equal to 40W, the first temperature threshold value when the terminal is charged is 42 ℃; the first temperature threshold at the time of terminal charging is 40 degrees celsius when the operating power of the application belongs to the range threshold (40W, 50W), that is, greater than 40W and equal to or less than 50W, and 38 degrees celsius when the operating power of the application belongs to the range threshold (50W, 60W), that is, greater than 50W and equal to or less than 60W.
Watch III
| Range threshold for operating power of an application | First temperature threshold value |
| [20W，40W] | 42 degrees centigrade |
| (40W，50W] | 40 degrees centigrade |
| (50W，60W] | 38 degrees centigrade |
In step 1036, the terminal uses the first temperature threshold as the upper temperature limit of the terminal during charging to adjust the operation parameters of the terminal during charging.
The terminal measures the magnitude relation between the body temperature and the first temperature threshold value, and adjusts the operation parameters of the terminal in the charging process. For example, alternatively, the terminal measures the body temperature of the terminal through a temperature sensor provided in the terminal; when the temperature of the machine body is greater than a first temperature threshold, the control terminal operates by adopting a first operation parameter corresponding to the first temperature threshold in the charging process; when the temperature of the machine body is smaller than the first temperature threshold, the control terminal operates by adopting a second operation parameter corresponding to the first temperature threshold in the charging process; the heating capacity corresponding to the first operation parameter is smaller than that corresponding to the second operation parameter.
In summary, in the method for controlling the terminal temperature according to the present embodiment, if the terminal is in the in-use state during the charging process of the terminal, the first temperature threshold of the terminal is determined according to the running power of the application running in the foreground of the terminal. The higher the running power of the application program running in the front end of the terminal is, the stronger the heating capacity of the terminal is, so that the running power of the application program running in the front end of the terminal and the first temperature threshold are in negative correlation, that is, the higher the running power of the application program running in the front end of the terminal is, the smaller the first temperature threshold is, so that the terminal can timely control the temperature rise of the terminal, and the terminal temperature is always in a range acceptable by a user while safe charging, thereby improving the user experience.
