Preferably an application running in the foreground.
Specifically, a regulation and control threshold may be preset, the regulation and control threshold is used as a temperature control condition, and when the detected temperature of the specified device of the mobile terminal is greater than or equal to the regulation and control threshold, it is determined that the temperature change of the specified device meets the preset temperature control condition, and information of the application program currently running in the mobile terminal is acquired. It can be understood that different regulation and control thresholds can be configured for different specified devices, and the regulation and control thresholds are managed through a regulation and control threshold index table, in which the correspondence between the specified devices and the corresponding regulation and control thresholds is recorded.
Or, defining a temperature change within a preset time as a temperature control condition, and when the temperature change of the specified device meets the defined temperature change, determining that the temperature change of the specified device meets the preset temperature control condition, and acquiring information of the currently running application program in the mobile terminal.

When detecting that the task for starting the application program is triggered, reducing the working frequency of the processor according to a preset frequency reduction rule, and running the application program at the reduced working frequency to regulate and control the temperature of the processor.
The method comprises the steps of counting acquired information of application programs, establishing a heating application list according to a counting result, and when a task of starting one application program in the heating application list is triggered, namely the application program is detected to be opened again, for example, when the operation of double-clicking the application program by a user is detected, reducing the working frequency of a processor according to a preset frequency reduction rule so as to pre-regulate and control the temperature of the processor and simultaneously start the application program.
And after detecting that the user finishes the finishing operation of the application program, restoring the working frequency of the processor to the normal working frequency.
The processor in the present invention mainly refers to a Central Processing Unit (CPU). Further, the method can also comprise the following steps: graphics Processing Unit (GPU). That is, the monitoring object may be a CPU or may be a CPU and a GPU, and the down-conversion object is preferably a CPU or may be a CPU and a GPU.

Or when detecting that the task for starting the application program is triggered, reducing the working frequency of the processor and simultaneously shutting down the core according to a preset frequency reduction rule.
In the processor temperature control method in the embodiment of the present invention, when the temperature change of the specific device of the mobile terminal meets the preset temperature control condition, the information of the application program running in the mobile terminal is acquired, and before the application program is restarted, the frequency of the processor is preset, so as to prevent the processor from having an excessively high temperature. Compared with the prior art that the frequency of the processor is reduced and adjusted after the temperature of the processor rises, the frequency reduction method and the frequency reduction device can effectively control the temperature of the processor by reducing the frequency of the processor before the application program which can cause the temperature of the processor to rise is started, and the temperature control effect is better.
second embodiment
referring to fig. 2, a second embodiment of the present invention provides a method for regulating processor temperature, including:
step S201, monitoring the temperature change of a designated device of the mobile terminal according to a preset time rule;
The mobile terminal is preset with a temperature control program, and the temperature control program monitors the temperature change of a specified device of the mobile terminal in real time or regularly according to a preset time rule in the running process of the mobile terminal. Wherein the designated devices may include, but are not limited to: any of a processor, a battery, a screen, and/or a body of the mobile terminal.
Step S202, when the temperature of the specified device is monitored to be larger than or equal to a preset regulation threshold value, acquiring information of an application program running in the mobile terminal;
the method comprises the steps of presetting a regulation and control threshold value in the mobile terminal, using the regulation and control threshold value as a temperature control condition, when the detected temperature of a specified device of the mobile terminal is larger than or equal to the regulation and control threshold value, determining that the temperature change of the specified device meets the preset temperature control condition, acquiring information of an application program currently running in the mobile terminal, such as the name of the application program currently running in the mobile terminal, and establishing a heating application list according to the acquired information of the application program. Wherein the application program may include: an application running in the foreground, or all applications running in the foreground and running in the background. Preferably an application running in the foreground.
step S203, when detecting that the task of starting the application program is triggered, continuously reducing the operating frequency of the processor, and when detecting that the operating frequency of the processor is less than or equal to the preset frequency or the frame rate of the application program is less than or equal to the preset frame rate, stopping reducing the frequency.
When detecting that a task for starting an application program in the heating application list is triggered, namely the application program is opened again, for example, when detecting that a user double-clicks the application program, the operating frequency of the processor is reduced according to a preset frequency reduction rule, and the application program is started at the same time.
Specifically, when it is detected that the user opens the application program in the heating application list again, the CPU frequency is adjusted in advance before the application program is run, the operating frequency of the CPU is continuously decreased, and when it is detected that the operating frequency of the CPU is less than or equal to a preset frequency or the frame rate (the number of Frames Per Second run, the larger the FPS, the smoother the screen switching on the screen) of the application program is less than or equal to a preset frame rate, the frequency decrease is stopped. The policy adopted here is to judge the operation efficiency of the application program through the FPS of the application program, for example: when the FPS is >60, the application runs with a very smooth feel, and when the FPS is <30, the application starts to run with a feeling of stuck. Therefore, in order to ensure the operating efficiency of the application program and enable the user to have a better usage experience, the CPU frequency is reduced, and considering the temperature and the FPS, the frequency is reduced as much as possible in the case that the FPS can be maintained above the preset frame rate (e.g., >30), and when the FPS is lower than the preset frame rate (e.g., < 30), the frequency is stopped from being reduced. It should be noted that the preset frame rate can be customized by a manufacturer according to a policy of performance preference or experience preference.
in the processor temperature control method in the embodiment of the present invention, when the temperature change of the specific device of the mobile terminal meets the preset temperature control condition, the information of the application program running in the mobile terminal is acquired, and before the application program is restarted, the frequency of the processor is preset, so as to prevent the processor from having an excessively high temperature. Compared with the prior art that the frequency of the processor is reduced and adjusted after the temperature of the processor rises, the frequency reduction method and the frequency reduction device can effectively control the temperature of the processor by reducing the frequency of the processor before the application program which can cause the temperature of the processor to rise is started, and the temperature control effect is better.
Third embodiment
Referring to fig. 3, a third embodiment of the present invention provides a method for regulating processor temperature, including:
Step S301, acquiring local air temperature;
specifically, the mobile terminal may obtain the local air temperature from the web server through the web interface. If the local air temperature cannot be obtained through the network, the System time is obtained, the position information of the mobile terminal is obtained through a Global Positioning System (GPS), the System time and the air temperature corresponding to the position information are inquired in a preset temperature index table, and the inquiry result is used as the local air temperature. The position information obtained through GPS positioning can be converted into a city, the current date, the day or the night can be obtained according to the current system time, then the current weather temperature is obtained through a built-in temperature index table and serves as the local air temperature, and therefore the corresponding regulation and control threshold value is determined according to the obtained current weather temperature. The average temperature of the major cities in the country at each time of the year is recorded in the temperature index table and is divided into daytime and nighttime.
step S302, if the local air temperature is greater than or equal to a preset maximum air temperature, determining a first threshold as the regulation threshold, if the local air temperature is less than or equal to a preset minimum air temperature, determining a second threshold as the regulation threshold, and if the local air temperature is between the maximum air temperature and the minimum air temperature, determining a third threshold as the regulation threshold;
Considering the influence of air temperature on the temperature of the CPU, for example, in winter, the CPU is less sensitive to heat generation, so when the local temperature is low, a looser temperature control algorithm can be adopted, for example, a lower regulation threshold value is adopted in exchange for more performance. When the local temperature is high, such as in summer, a stricter temperature control algorithm is adopted, such as a higher regulation threshold value, so as to prevent heating.
specifically, if the local air temperature is greater than or equal to the preset highest air temperature, determining that the current time is summer, adopting a stricter temperature control algorithm to determine a first threshold as a regulation threshold, and acquiring information of the currently running application program when the temperature of the CPU reaches the lower first threshold; if the local air temperature is less than or equal to the preset lowest air temperature, determining that the current time is in winter, adopting a looser temperature control algorithm, determining a second threshold as a regulation threshold, and acquiring the information of the currently running application program when the temperature of the CPU reaches a higher second threshold; and if the local air temperature is between the highest air temperature and the lowest air temperature, determining that the current season is spring and autumn, and determining a third threshold as a regulation threshold by adopting a common temperature control algorithm, wherein the first threshold is the smallest, the second threshold is the largest, and the third threshold is between the first threshold and the second threshold, namely the first threshold is less than the third threshold and less than the second threshold.
Step S303, monitoring the temperature change of a designated device of the mobile terminal according to a preset time rule;
the mobile terminal is preset with a temperature control program, and the temperature control program monitors the temperature change of a specified device of the mobile terminal in real time or regularly according to a preset time rule in the running process of the mobile terminal. Wherein the designated devices may include, but are not limited to: any of a processor, a battery, a screen, and/or a body of the mobile terminal.
Step S304, when the temperature of the specified device is monitored to be larger than or equal to a preset regulation and control threshold value and the temperature changes in a continuously rising trend within a preset monitoring time, acquiring information of an application program running in the mobile terminal and recording the screen brightness value of the mobile terminal;
When the temperature of the specified device is monitored to be larger than or equal to a preset regulation threshold value, if the temperature value of the specified device is continuously obtained within a preset monitoring time period, for example, the temperature value of a CPU thermistor is continuously obtained, if the continuously obtained temperature value is in an ascending trend at the moment, information of an application program running in the mobile terminal is obtained and recorded, so that the CPU frequency is regulated in advance when the application program is started next time, and meanwhile, the screen brightness value of the mobile terminal is recorded. It will be appreciated that if the continuously acquired temperature values are trending downward, the application is not recorded. The reason for this is that although the detected temperature is greater than or equal to the regulation threshold, it may be caused by that another application program is previously started, and although the other application program is already closed, since the temperature does not quickly decrease below the regulation threshold, if the change of the acquired temperature value is in a downward trend, it indicates that the reason for the current temperature being too high is not the application program currently running, and no recording is performed. Therefore, the application program causing the overhigh temperature of the processor can be more accurately determined, and the regulation and control efficiency is ensured.
the method comprises the steps of obtaining information of an application program currently running in the mobile terminal, such as the name of the application program currently running in the mobile terminal, and establishing a heating application list according to the obtained information of the application program. Wherein, the application program can comprise: an application running in the foreground, or all applications running in the foreground and running in the background. Preferably an application running in the foreground.
further, the peripheral devices turned on in the mobile terminal are recorded besides the screen brightness value, such as: WIFI, bluetooth, GPS, etc. other operating environment data.
Step S305, when detecting that the task for starting the application program is triggered, continuously reducing the working frequency of the processor, and when detecting that the working frequency of the processor is less than or equal to the preset frequency or the frame rate of the application program is less than or equal to the preset frame rate, stopping reducing the frequency;
when detecting that a task for starting an application program in the heating application list is triggered, namely the application program is opened again, for example, when detecting that a user double-clicks the application program, the operating frequency of the processor is reduced according to a preset frequency reduction rule, and the application program is started at the same time.
specifically, when it is detected that the user opens the application program in the heating application list again, the frequency of the CPU is reduced in advance before the application program runs, the operating frequency of the CPU is continuously reduced, and when it is detected that the operating frequency of the CPU is less than or equal to a preset frequency or a frame rate (FPS) of the application program is less than or equal to a preset frame rate, the frequency reduction is stopped. The policy adopted here is to judge the operation efficiency of the application program through the FPS of the application program, for example: when the FPS is >60, the application runs with a very smooth feel, and when the FPS is <30, the application starts to run with a feeling of stuck. Therefore, in order to ensure the operating efficiency of the application program and enable the user to have a better usage experience, the CPU frequency is reduced, and considering the temperature and the FPS, the frequency is reduced as much as possible in the case that the FPS can be maintained above the preset frame rate (e.g., >30), and when the FPS is lower than the preset frame rate (e.g., < 30), the frequency is stopped from being reduced. It should be noted that the preset frame rate can be customized by a manufacturer according to a policy of performance preference or experience preference.
S306, obtaining the brightness value of the current screen of the mobile terminal, and reducing the brightness value of the screen to a preset brightness value if the brightness value of the current screen is greater than or equal to the recorded screen brightness value.
And comparing the acquired brightness value of the current screen with the previously recorded screen brightness value, and reducing the brightness value of the screen to a preset brightness value if the brightness value of the current screen is greater than or equal to the previously recorded screen brightness value. Wherein the preset brightness value may or may not be equal to the previously recorded screen brightness value. By adjusting the screen brightness, the temperature of the processor can be further controlled, and adverse effects on the temperature of the processor caused by overhigh screen brightness are eliminated.
further, the peripheral equipment which is currently opened by the mobile terminal is obtained, the number of the currently opened peripheral equipment is compared with the number of the previously recorded opened peripheral equipment, and if the number of the currently opened peripheral equipment is larger than or equal to the recorded number of the opened peripheral equipment, idle peripheral equipment in the currently opened peripheral equipment is closed. Specifically, the mobile terminal can determine whether the opened peripheral is an idle peripheral by detecting whether data is being transmitted through interfaces of the peripherals, determine the peripheral without data transmission as the idle peripheral, and close the peripheral. By closing the idle peripherals, the temperature of the processor can be further controlled, and adverse effects on the temperature of the processor due to simultaneous operation of a plurality of peripherals are eliminated.
it should be noted that step S306 may be performed simultaneously with step S305, that is, the processor is down-clocked while the brightness of the screen is adjusted and the idle peripherals are turned off.
in the processor temperature control method in the embodiment of the present invention, when the temperature change of the specific device of the mobile terminal meets the preset temperature control condition, the information of the application program running in the mobile terminal is acquired, and before the application program is restarted, the frequency of the processor is preset, so as to prevent the processor from having an excessively high temperature. Compared with the prior art that the frequency of the processor is reduced and adjusted after the temperature of the processor rises, the frequency reduction method and the frequency reduction device can effectively control the temperature of the processor by reducing the frequency of the processor before the application program which can cause the temperature of the processor to rise is started, and the temperature control effect is better.
