Description

Stable frame scheduling method, device, terminal equipment and computer-readable storage medium

Technical Field

The present application belongs to the field of computer application technology, and in particular, relates to a stable frame scheduling method, device, terminal equipment and computer-readable storage medium.

Background Art

With the widespread popularity and rapid development of terminal devices such as smartphones, the functions of terminal devices such as smartphones are becoming more and more complete. For example, users can run various types of game applications for entertainment through smartphones. When running large-scale game applications and other high-power applications in terminal devices, due to complex scenarios and frequent interactions, it brings huge challenges to resource scheduling and power consumption optimization. Especially in some high-power game applications, long-term operation will cause the terminal device temperature to be too high, resulting in low-temperature burns to users, and irreversible damage to system hardware (such as screens, batteries, motherboards, etc.).

In the related art, for some high-power gaming applications, a temperature control, frequency limiting and frame limiting strategy is usually used to prevent the terminal device from overheating. That is, when the temperature of the terminal device exceeds a certain limit, the frame rate and frequency of the gaming application are reduced to a certain level to reduce the temperature of the terminal device. However, as the gaming time continues to increase, this frame and frequency limiting strategy will not only cause a sharp decline in system performance, and fail to bring into play the full computing power of the system's central processor and graphics processor, but will also cause a sharp drop in frame rate, resulting in frame drops and freezes, which seriously affects the user experience.

The stable frame scheduling method, apparatus, terminal device, storage medium and computer program provided by the present application are described in detail below with reference to the accompanying drawings.

FIG1 shows a schematic flow chart of a stable frame scheduling method provided in an embodiment of the present application.

As shown in FIG1 , the stable frame scheduling method includes the following steps:

Step 101, obtaining the expected frame rate and current frame rate corresponding to the current application.

It should be noted that the stable frame scheduling method of the embodiment of the present application can be executed by the stable frame scheduling device of the embodiment of the present application. The stable frame scheduling device of the embodiment of the present application can be configured in any terminal device to execute the stable frame scheduling method of the embodiment of the present application. For example, the stable frame scheduling device of the embodiment of the present application can be configured in a terminal device such as a mobile phone, a computer, a wearable device, etc., to perform stable frame processing during the application operation process.

The current application may refer to an application currently running in the foreground of the terminal device and requiring frame stabilization processing. For example, the current application may be a video application, a game application, or other application with high power consumption currently running in the foreground of the terminal device.

The expected frame rate may be the optimal frame rate that the current application expects to achieve. As an example, the expected frame rate may be the default optimal frame rate of the current application, or the highest frame rate supported by the terminal device where the current application is located; or, it may be the frame rate set by the user after starting the current application, which is not limited in the embodiments of the present application.

It should be noted that if the application allows the user to select the optimal frame rate expected to be achieved when starting the application, the expected frame rate can be determined as the frame rate set by the user, so that the frame rate of the application can be determined according to the user's needs when the terminal device's operating conditions allow during the application. In addition, if the frame rate set by the user is greater than the maximum frame rate supported by the terminal device, the maximum frame rate supported by the terminal device can be determined as the expected frame rate of the current application.

The current frame rate may refer to the frame rate of the current application at the current moment.

In an embodiment of the present application, the application currently running in the foreground of the terminal device can be determined as the current application, and after the current application is started, the optimal frame rate that the current application expects to achieve can be obtained and determined as the expected frame rate, and the frame rate of the current application at the current moment can be obtained and determined as the current frame rate.

As a possible implementation method, if the current application does not allow the user to set the expected frame rate by himself, the default optimal frame rate of the current application can be determined as the expected frame rate, or the highest frame rate supported by the terminal device where the current application is located can also be determined as the expected frame rate; if the current application allows the user to set the expected frame rate by himself, then after the current application is started, the expected frame rate setting dialog box can be displayed in the display interface after the current application is started, so that the user can select or enter the expected frame rate through the expected frame rate setting dialog box, and then the frame rate selected or entered by the user in the expected frame rate setting dialog box can be determined as the expected frame rate.

As a possible implementation method, in order to reduce the resource scheduling pressure of the terminal device while ensuring the application display effect, stable frame scheduling can be performed only for the applications installed in the terminal device that have high power consumption, complex scenarios, or high frame rate requirements. Therefore, a preset application list that needs to be stable frame scheduled can be generated based on the applications installed in the terminal device, and when the application currently running in the foreground of the terminal device is an application in the preset application list, the application is determined as the current application, and the stable frame scheduling method of the present application is used to perform stable frame scheduling on the application; if the application currently running in the foreground of the terminal device is not an application in the preset application list, the application may not be determined as the current application, that is, the stable frame scheduling method of the present application may not be used to perform stable frame scheduling on the application, so as to save the computing resources of the terminal device when it is not necessary.

As a possible implementation method, a preset application type that needs to be scheduled for stable frame can also be pre-set. Therefore, when the application type of the application currently running in the foreground of the terminal device is the preset application type, the application can be determined as the current application, and the stable frame scheduling method of the present application can be used to perform stable frame scheduling on the application; when the application type of the application currently running in the foreground of the terminal device is not the preset application type, the application may not be determined as the current application, that is, the stable frame scheduling method of the present application may not be used to perform stable frame scheduling on the application, so as to save the computing resources of the terminal device when unnecessary.

As an example, a preset application list or preset application type can be set according to the power consumption of the applications installed in the terminal device. For example, applications with power consumption greater than or equal to the power consumption threshold can be added to the preset application list; or, the average power consumption of each type of application installed in the terminal device can be determined, and the application type with average power consumption greater than the power consumption threshold can be determined as the preset application type. For example, large-scale game applications, video applications, etc. can be determined as preset application types, or large-scale game applications, video applications, etc. installed in the terminal device can be added to the preset application list.

As an example, in order to make the stable frame scheduling effect of each application in the terminal device more in line with the user's personalized needs, it is also possible to run user-defined applications that require stable frame scheduling. Therefore, the user can be allowed to select the application that needs to be scheduled for stable frame in the setting menu of the terminal device, and the application selected by the user can be added to the preset application list; or, the user can be allowed to select the application type that needs to be scheduled for stable frame in the setting menu of the terminal device, and the application type selected by the user can be determined as the preset application type that needs to be scheduled for stable frame.

It should be noted that the above-listed methods for determining applications that require stable frame scheduling are only exemplary and cannot be regarded as limitations on this application. In actual use, the applications that require stable frame scheduling and the methods of setting them can be set according to actual needs and specific application scenarios, and this embodiment of the application does not limit this.

Step 102, obtaining the current temperature of the terminal device where the current application is located and the historical temperatures at multiple historical moments, wherein the historical moment refers to the display moment of multiple historical data frames before the current data frame.

The current temperature may refer to the temperature of the terminal device at the current moment.

The current data frame may refer to a data frame in the current application displayed by the terminal device at the current moment. It should be noted that the current moment in the embodiment of the present application is the display moment of the current data frame.

Among them, historical data frames may refer to multiple data frames displayed before the current data frame and adjacent to the current data frame; correspondingly, historical moments are multiple display moments that are before the current moment and adjacent to the current moment. For example, if the current data frame is the 101st data frame displayed after the current application is started, the historical data frames may be the 81st to 100th data frames, and the historical moments are the display moments of the 81st to 100th data frames.

It should be noted that in actual use, the number of historical temperatures collected can be set according to actual needs and specific application scenarios, and the present application embodiment does not limit this. For example, the historical temperatures of the terminal device at 20 or 50 historical moments can be collected, and so on.

In an embodiment of the present application, a temperature sensor can be configured in the terminal device to collect the temperature when the terminal device is running, and then the temperature collected by the temperature sensor at the current moment can be determined as the current temperature, and the temperature collected by the temperature sensor at each historical moment can be determined as each historical temperature.

Step 103, determining the predicted temperature of the terminal device after a preset time period according to the expected frame rate, the current temperature and various historical temperatures.

Among them, the predicted temperature may refer to the temperature that the terminal device may reach after a period of time, based on the current and previous historical operating conditions (historical temperature) of the terminal device. It should be noted that since the predicted temperature is the temperature that the terminal device may reach after a period of time, based on the current temperature and historical temperature of the terminal device, the predicted temperature can reflect the operating conditions of the terminal device after a period of time, so that the temperature of the terminal device can be predicted in time through the predicted temperature, so as to schedule the frame rate of the current application in advance, thereby ensuring the frame rate stability of the current application, and preventing the frame rate of the current application from being adjusted significantly after the terminal device temperature is too high, resulting in a sudden drop in the frame rate, so as to improve the operating stability and display effect of the current application.

The preset duration can be set according to actual needs and specific application scenarios, and the present application embodiment does not limit this. For example, the preset duration can be 1 minute (i.e., predicting the temperature of the terminal device 1 minute later), 2 minutes, 5 minutes, and so on.

In an embodiment of the present application, multiple historical temperatures of the terminal device can reflect the temperature changes of the terminal device in the time period between the earliest historical moment obtained and the current moment (hereinafter this time period is referred to as the current historical time period). Therefore, the temperature changes of the terminal device can be determined based on the multiple historical temperatures of the terminal device and the length of the current historical time period, and then the predicted temperature after the preset time length can be determined based on the preset time length and the temperature changes of the terminal device.

It should be noted that the earliest historical moment may refer to the earliest historical moment corresponding to each historical temperature acquired at the current moment. For example, if the current data frame is the 101st data frame displayed in the current application, and each historical data frame is the 81st to 100th data frame, then the earliest historical moment refers to the display moment of the 81st data frame, and the current historical period refers to the period between the display moment of the 81st data frame and the current moment (i.e., the display moment of the 101st data frame). In addition, when the method of the present application is used to perform stable frame scheduling on the current application, it can be determined whether the current frame rate of the current application needs to be adjusted when each data frame is displayed. Therefore, the actual frame rate of the current application at each historical moment in the current historical period may be constantly changing, and the current historical period is usually very short. Therefore, directly determining the length of the current historical period by the difference between the earliest historical moment and the current moment is usually not accurate enough. Therefore, the expected frame rate can be used instead of the frame rate of the current application in the current historical period, and the length of the current historical period is determined based on the ratio of the number of data frames included in the current historical period to the expected frame rate, so as to improve the accuracy of determining the temperature change of the terminal device, thereby improving the accuracy of the stable frame scheduling.

Furthermore, the temperature change of the terminal device can be represented by the temperature rise rate to quantify the temperature change of the terminal device, improve the accuracy of the predicted temperature determination, and further improve the reliability of the stable frame scheduling. That is, in a possible implementation of the embodiment of the present application, the above step 103 may include:

Determine the temperature rise rate corresponding to the terminal device based on the expected frame rate and each historical temperature;

Determine the predicted temperature based on the current temperature, temperature rise rate and preset duration.

As a possible implementation method, the number of historical temperatures obtained at the current moment can be determined as the number of temperatures n included in the current historical period. Assuming that the expected frame rate is fps, the duration of the current historical period can be n/fps. Afterwards, the ratio of the sum of each historical temperature to the duration of the current historical period can be determined as the temperature rise rate corresponding to the terminal device. That is, the temperature rise rate corresponding to the terminal device can be determined by formula (1):

Among them, v is the temperature rise rate corresponding to the terminal device, _ti is the historical temperature at the i-th historical moment, n is the number of temperatures included in the current historical period, i is the sequence number of the historical temperature, and fps is the expected frame rate.

As a possible implementation method, since the terminal device needs to achieve a high frame rate when performing animation or video display so that the human eye can feel that the picture is continuously changing, the time interval between the display moments of two adjacent data frames is usually very short, so that the historical temperature directly collected by the temperature sensor at each historical moment usually has a certain error and randomness. Therefore, for a historical moment, the temperature of the historical moment can be obtained by using the temperatures of multiple historical moments adjacent to the historical moment to ensure the reliability of the temperature rise rate determination. That is, in a possible implementation method of the embodiment of the present application, the above-mentioned determination of the temperature rise rate corresponding to the terminal device based on the expected frame rate and each historical temperature may include:

Determine a temperature control window corresponding to each historical moment, wherein each temperature control window includes a preset number of historical temperatures;

According to each historical temperature included in each temperature control window, determine the average historical temperature corresponding to each historical moment;

Determine the temperature control duration based on the number of historical moments and the expected frame rate;

Determine the temperature rise rate based on the average historical temperatures and temperature control duration.

The temperature control window may refer to an empty sequence with a preset length. In actual use, the specific value of the preset number (i.e., the length of the temperature control window) may be determined according to actual needs and specific application scenarios, and the present application embodiment does not limit this. For example, the preset number may be 3, 5, 10, and so on.

Among them, the temperature control window corresponding to the historical moment may refer to a sequence generated by filling the temperature control window with the historical temperature of the historical moment and the historical temperatures of multiple historical moments before and adjacent to the historical moment as elements of the temperature control window.

For example, assuming that the preset number is 5, that is, the length of the temperature control window is 5, and assuming that the historical moments include the display moments of the 81st to 100th data frames, where the historical temperature at the display moment of the 90th data frame is 32 degrees, and the historical temperatures at the display moments of the 89th, 88th, 87th, and 86th data frames are 32 degrees, 31.5 degrees, 32 degrees, and 32.1 degrees, respectively, then the temperature control window corresponding to the display moment of the 90th data frame is [32 32 31.5 32 32.1].

The average historical temperature corresponding to a historical moment may refer to the average value of each historical temperature included in the temperature control window corresponding to the historical moment.

In the embodiment of the present application, after determining the temperature control windows corresponding to n historical moments, the average values of the historical temperatures included in the n temperature control windows can be determined respectively, and used as the average historical temperatures corresponding to the n historical moments respectively. Then, the temperature control duration is determined based on the ratio of the number of historical moments to the expected frame rate, and then the ratio of the sum of the average historical temperatures to the temperature control duration is determined as the temperature rise rate corresponding to the terminal device. That is, the temperature rise rate corresponding to the terminal device can be determined by formula (2) and formula (3):

Wherein, v is the temperature rise rate corresponding to the terminal device, avg( _ti ) is the average historical temperature corresponding to the i-th historical moment, n is the number of historical moments included in the current historical period, i is the sequence number of the historical moment, fps is the expected frame rate, a is the preset number, and _tij is the j-th historical temperature in the temperature control window corresponding to the i-th historical moment.

In the embodiment of the present application, after determining the temperature rise rate corresponding to the terminal device, the predicted temperature of the terminal device after the preset time period can be determined according to the current temperature at the current moment, the temperature rise rate and the preset time period. As an example, the predicted temperature of the terminal device after the preset time period can be determined by formula (4):

t＝t ₀ +dur×v(4)

Among them, t is the predicted temperature of the terminal device after the preset time, _t0 is the current temperature, dur is the preset time, and v is the temperature rise rate corresponding to the terminal device.

Furthermore, since the system temperature and shell temperature of the terminal device will affect the performance and user experience of the terminal device, when predicting the temperature of the terminal device, the system temperature and shell temperature of the terminal device can be predicted separately to further improve the reliability of stable frame scheduling. That is, in a possible implementation of the embodiment of the present application, the current temperature includes the current system temperature and the current shell temperature, and the historical temperature includes the historical system temperature and the historical shell temperature; accordingly, the step 103 may include:

Determine the predicted system temperature of the terminal device after a preset time period based on the expected frame rate, the current system temperature and various historical system temperatures;

Determine the predicted shell temperature of the terminal device after a preset time period based on the expected frame rate, the current shell temperature and each historical shell temperature;

Determine the predicted temperature based on the predicted system temperature and the predicted shell temperature.

Among them, the system temperature may include at least one of the temperatures of the core hardware of the terminal device, such as the central processing unit (CPU) temperature, the motherboard temperature, the graphics card temperature, the hard disk temperature, and the memory temperature; or, the system temperature may also be the overall temperature obtained by weighting one or more of the above core hardware temperatures.

For example, assuming that the system temperature is determined based on the CPU temperature and the motherboard temperature, as an example, the average value of the CPU temperature and the motherboard temperature collected at the same time can be determined as the system temperature at that moment; as another example, the weighted sum of the CPU temperature and the motherboard temperature collected at the same time can also be determined as the system temperature at that moment, wherein the weights corresponding to the CPU and motherboard temperatures can be determined according to actual needs, and the embodiments of the present application are not limited to this.

It should be noted that, in actual use, the temperature type of the core hardware used to determine the system temperature can be determined according to the actual components in the terminal device or the actual usage requirements, and the embodiments of the present application do not limit this. For example, in order to save computing power, the most important CPU temperature can be directly used as the system temperature; or, when the terminal device is a computer, since the computer has complete components and high computing power, the system temperature can be determined based on the CPU temperature, motherboard temperature, graphics card temperature, and hard disk temperature; when the terminal device is a mobile phone, since there may be no hard disk, graphics card and other components in the mobile phone, and the computing power of the mobile phone is relatively weak, the system temperature can be determined based on the CPU temperature and the motherboard temperature, or the CPU temperature can be directly determined as the system temperature, and so on.

The shell temperature may refer to the temperature of the shell of the terminal device.

The current system temperature may refer to the system temperature of the terminal device at the current moment; the current shell temperature may refer to the shell temperature of the terminal device at the current moment.

In the embodiment of the present application, a temperature sensor can be set at one or more core hardware such as the CPU, motherboard, hard disk, and graphics card of the terminal device, and a temperature sensor can be set at a suitable position near the shell of the terminal device to collect the temperature of these core hardware and the shell temperature of the terminal device in real time, and determine the system temperature and shell temperature of the terminal device at the display time of each data frame according to the temperature collected by each temperature sensor at the display time of each data frame of the current application, so as to determine the current system and current shell temperature of the terminal device, as well as the historical system temperature and historical shell temperature of the terminal device at multiple historical moments corresponding to the current moment. After that, the system temperature of the terminal device after a preset time can be predicted based on the expected frame rate, the current system temperature, that is, each historical system temperature, to obtain the predicted system temperature; and the shell temperature of the terminal device after a preset time can be predicted based on the expected frame rate, the current shell temperature, and each historical shell temperature, to obtain the predicted shell temperature. Furthermore, the predicted temperature of the terminal device after a preset time can be determined based on the predicted system temperature and the predicted shell temperature.

As an example, the average value of the predicted system temperature and the predicted shell temperature may be determined as the predicted temperature of the terminal device after a preset period of time.

As an example, different weights can be set for the predicted system temperature and the predicted shell temperature, respectively, and then the weighted sum of the predicted system temperature and the predicted shell temperature is determined as the predicted temperature of the terminal device after a preset time. That is, the predicted temperature of the terminal device after a preset time can be determined by formula (5):

t＝λT _s +(1-λ) _Th (5)

Wherein, t is the predicted temperature of the terminal device after a preset time, _Ts is the predicted system temperature of the terminal device after a preset time, _Th is the predicted shell temperature of the terminal device after a preset time, and λ is the weight of the predicted system temperature.

It should be noted that in actual use, the specific value of λ can be determined according to actual needs and specific application scenarios, and the embodiments of the present application do not limit this. For example, when the terminal device is a mobile phone, the shell temperature usually directly affects the user experience, so the weight of the predicted shell temperature can be set to a larger value, such as λ can be set to 0.4, that is, the weight of the predicted shell temperature 1-λ is 0.6.

As a possible implementation method, when determining the predicted system temperature and the predicted shell temperature, the system temperature rise rate corresponding to the terminal device can be determined based on the expected frame rate and each historical system temperature, and the predicted system temperature can be determined based on the current system temperature, the system temperature rise rate and the preset duration; correspondingly, the shell temperature rise rate corresponding to the terminal device can be determined based on the expected frame rate and each historical shell temperature, and the predicted shell temperature can be determined based on the current shell temperature, the shell temperature rise rate and the preset duration.

It should be noted that the method for determining the system temperature rise rate and the shell temperature rise rate can be the same as the specific method for determining the temperature rise rate corresponding to the terminal device according to the expected frame rate and each historical temperature in the aforementioned embodiment, that is, the historical system temperature at each historical moment is substituted into formula (1), or into formulas (2) and (3), so as to determine the system temperature rise rate; and the historical shell temperature at each historical moment is substituted into formula (1), or into formulas (2) and (3), so as to determine the shell temperature rise rate; and the method for determining the predicted system temperature according to the system temperature rise rate and the method for determining the predicted shell temperature according to the shell temperature rise rate can also be the same as the method for determining the predicted temperature according to the current temperature, the temperature rise rate and the preset time in the aforementioned embodiment, that is, the current system temperature and the system temperature rise rate are substituted into formula (4), so as to determine the predicted system temperature; and the current shell temperature and the shell temperature rise rate are substituted into formula (4), so as to determine the predicted shell temperature. For other specific implementation processes and principles, please refer to the detailed description of the aforementioned embodiment, which will not be repeated here.

Step 104: Determine a frame rate adjustment strategy corresponding to the current application according to the predicted temperature.

In an embodiment of the present application, after determining the predicted temperature of the terminal device after a preset period of time, the operating status and temperature status of the terminal device in the future can be predicted in advance based on the predicted temperature, and then the frame rate adjustment strategy corresponding to the current application can be determined based on the predicted temperature, so as to intervene in the current frame rate of the current application in advance, prevent the frame rate of the current application from being adjusted after the temperature of the terminal device is too high, avoid a sudden drop in frame rate, and avoid a series of problems such as frame dropping, frame jamming, unstable operation, etc. caused by the sudden drop in frame rate.

As a possible implementation method, when the predicted temperature of the terminal device after a preset period of time is high, it means that if the terminal device continues to maintain the current frame rate, there may be a risk of overtemperature. Therefore, the current frame rate of the current application can be reduced, that is, the frame rate adjustment strategy can be determined to reduce the current frame rate to advance and slowly reduce the frame rate of the current application; when the predicted temperature of the terminal device after the preset period of time is low, it means that the terminal device is currently operating in good condition and there is no risk of overtemperature. Therefore, the current frame rate of the current application can be kept unchanged to ensure the display and operation smoothness of the application as much as possible while ensuring the operating stability of the terminal device.

It should be noted that in the embodiment of the present application, the frame reduction amplitude can be preset, so that when the frame rate adjustment strategy is to reduce the current frame rate, the current frame rate can be reduced by the preset frame reduction amplitude; and the preset frame reduction amplitude can be a smaller value, such as 1fps, 2fps, 3fps, etc., to achieve the purpose of slowly reducing the frame rate. For example, if the current frame rate is 90fps and the frame rate adjustment strategy is to reduce the current frame rate, the current frame rate can be adjusted to 89fps.

Furthermore, the reliability of stable frame scheduling can be further improved by setting a temperature threshold of the terminal device and using the temperature threshold as a standard to determine whether the terminal device has a risk of over-temperature. That is, in a possible implementation of the embodiment of the present application, the above step 104 may include:

When the predicted temperature is less than or equal to the first warning temperature, the frame rate adjustment strategy is determined to keep the current frame rate unchanged;

When the predicted temperature is greater than the first warning temperature, the frame rate adjustment strategy is determined to reduce the current frame rate.

The first warning temperature may refer to an upper limit of an acceptable temperature value that will not have a significant impact on the operating status of the terminal device; that is, when the temperature of the terminal device exceeds the first warning temperature, it may have some impact on the performance of the terminal device. In actual use, the value of the first warning temperature may be determined according to actual needs and specific application scenarios, and the embodiments of the present application do not limit this.

As a possible implementation method, if the predicted temperature is less than or equal to the first warning temperature, it means that the temperature of the terminal device will remain at a low level after the preset period of time, so that the frame rate adjustment strategy can be determined to keep the current frame rate unchanged to ensure the smoothness of the display and operation of the current application; if the predicted temperature is greater than the first warning temperature, it means that the temperature of the terminal device may rise to a higher level after the preset period of time, so that the frame rate adjustment strategy can be determined to reduce the current frame rate to slowly reduce the frame rate before the temperature of the terminal device is too high, so as to achieve the purpose of controlling the temperature of the terminal device while ensuring the smoothness and stability of the application display and operation.

Furthermore, when frame reduction processing is required, different frame reduction amplitudes can be used to reduce the frame rate according to the level of the predicted temperature of the terminal device, so that when the predicted temperature is not ideal, the frame can be reduced more quickly and smoothly to prevent the terminal device from overheating. That is, in a possible implementation of the embodiment of the present application, when the predicted temperature is greater than the first warning temperature, the frame rate adjustment strategy is determined to reduce the current frame rate, which may include:

When the predicted temperature is greater than the first warning temperature and less than or equal to the second warning temperature, the frame rate adjustment strategy is determined to reduce the current frame rate by the first frame reduction amplitude, wherein the second warning temperature is greater than the first warning temperature;

When the predicted temperature is greater than the second warning temperature, the frame rate adjustment strategy is determined to reduce the current frame rate by a second frame reduction amplitude, wherein the second frame reduction amplitude is greater than the first frame reduction amplitude.

The second warning temperature may refer to the lower limit of the temperature value that will have a significant impact on the operating status of the terminal device; that is, when the temperature of the terminal device exceeds the second warning temperature, the performance of the terminal device may be significantly reduced. In actual use, the specific value of the second warning temperature can be set according to actual needs and specific application scenarios, and the embodiments of the present application do not limit this.

The first frame reduction amplitude and the second frame reduction amplitude are usually both small values, and the specific values can be determined according to actual needs and specific application scenarios, and the embodiment of the present application does not limit this. For example, the first frame reduction amplitude is 1fps, the second frame reduction amplitude is 3fps, and so on.

As a possible implementation method, if the predicted temperature is greater than the first warning temperature and less than or equal to the second warning temperature, it means that the temperature of the terminal device after the preset time may be high but within an acceptable range, so that the frame rate can be slowly reduced with a smaller frame reduction amplitude, that is, the frame rate adjustment strategy can be determined to reduce the current frame rate with a smaller first frame reduction amplitude to further improve the stability when reducing the frame rate; if the predicted temperature is greater than the second warning temperature, it means that the temperature of the terminal device after the preset time may be too high, so that the frame rate can be reduced slightly faster with a larger frame reduction amplitude, that is, the frame rate adjustment strategy can be determined to reduce the current frame rate with a larger second frame reduction amplitude, so as to adjust the frame rate to a safe range as quickly as possible under the premise of slowly reducing the frame rate, so as to prevent the terminal device from being overheated and ensure the stability of the terminal device operation.

It should be noted that in actual use, more warning temperatures can be set to divide the predicted temperature into more and more detailed temperature ranges, and different temperature ranges can correspond to different frame reduction amplitudes, so as to schedule the application's frame rate in a more detailed and accurate manner, further improving the reliability and stability of stable frame scheduling.

Furthermore, a frame stabilization decision model can be pre-trained, and the frame stabilization decision model can be used to directly output the current frame rate adjustment strategy based on the current temperature and historical temperature of the terminal device, so as to further improve the reliability and stability of the frame stabilization scheduling, and further improve the display and operation fluency of the application. That is, in a possible implementation of the embodiment of the present application, the predicted temperature can be determined by using a pre-trained frame stabilization decision model, and the pre-trained mapping relationship between the temperature and the frame rate adjustment strategy can also be included in the pre-trained frame stabilization decision model; accordingly, the above step 104 can include:

According to the predicted temperature and the mapping relationship between the temperature and the frame rate adjustment strategy, the frame rate adjustment strategy corresponding to the predicted temperature is determined as the frame rate adjustment strategy.

As a possible implementation method, the calculation method of the predicted temperature in steps 101-103 of the embodiment of the present application can be used as a part of the algorithm in the stable frame decision model, so as to directly calculate the predicted temperature of the terminal device after the preset time length through the stable frame decision model. In the embodiment of the present application, a large amount of temperature data of a large number of terminal devices and the frame rate data of the current application can be obtained in advance, and the stable frame decision model can be trained until an accurate mapping relationship between temperature and frame rate adjustment strategy is generated, that is, the stable frame decision model can be used for stable frame scheduling. That is, in the embodiment of the present application, after the current temperature of the terminal device, the historical temperature at each historical moment, the preset time length and the expected frame rate, and the current frame rate can be input into the stable frame decision model, the stable frame decision model can calculate the predicted temperature of the terminal device after the preset time length according to these parameters, and then directly according to the predicted temperature and the mapping relationship between the pre-trained temperature and the frame rate adjustment strategy, the frame rate adjustment strategy corresponding to the predicted temperature can be directly determined as the current frame rate adjustment strategy and output, so that the terminal device can adjust the current frame rate according to the frame rate adjustment strategy output by the stable frame decision model.

It should be noted that the pre-trained mapping relationship between temperature and frame rate adjustment strategy in the embodiment of the present application may include a large number of mapping relationships between temperature and frame rate adjustment strategies, that is, each different temperature may correspond to a different frame rate adjustment strategy, thereby achieving a more refined and accurate stable frame scheduling effect, and further improving the reliability and stability of stable frame scheduling.

Step 105: adjust the current frame rate according to the frame rate adjustment strategy.

In the embodiment of the present application, after the current frame rate adjustment strategy is determined, the current frame rate of the current application can be adjusted according to the frame rate adjustment strategy.

As a possible implementation, if the frame rate adjustment strategy is to keep the current frame rate unchanged, the current frame rate can be kept unchanged; if the frame rate adjustment strategy is to reduce the current frame rate, the current frame rate can be reduced according to a preset frame reduction range.

As a possible implementation method, if the frame rate adjustment strategy is to reduce the current frame rate by a first frame reduction amplitude, the current frame rate can be reduced by the first frame reduction amplitude; if the frame rate adjustment strategy is to reduce the current frame rate by a second frame reduction amplitude, the current frame rate can be reduced by the second frame reduction amplitude.

The stable frame scheduling method provided in the embodiment of the present application predicts the temperature of the terminal device after a preset period of time based on multiple historical temperatures of the terminal device, so as to make an early judgment on the temperature condition of the terminal device, and slowly reduce the frame rate of the application in advance when it is predicted that the temperature may be too high, thereby avoiding a cliff drop in the frame rate of the application, solving the problem of frame drops and stuttering caused by a sudden drop in the frame rate, and improving the user experience.

In a possible implementation form of the present application, in order to ensure the stability of the frame rate and to make the frame rate of the application as optimal as possible when the operating conditions of the terminal device permit, the frame rate tolerance can be used to constrain the fluctuation range of the frame rate. Therefore, when scheduling the frame rate of the application, the frame rate tolerance can also be adjusted according to the real-time temperature conditions to further improve the stability and reliability of stable frame scheduling and further improve the user experience.

The stable frame scheduling method provided in the embodiment of the present application is further described below in conjunction with FIG. 2 .

FIG2 shows a schematic flow chart of another stable frame scheduling method provided in an embodiment of the present application.

As shown in FIG2 , the stable frame scheduling method includes the following steps:

Step 201, obtaining the expected frame rate and current frame rate corresponding to the current application.

Step 202, obtaining the current temperature of the terminal device where the current application is located and the historical temperatures at multiple historical moments, wherein the historical moment refers to the display moment of multiple historical data frames before the current data frame.

Step 203, determining the predicted temperature of the terminal device after a preset time period according to the expected frame rate, the current temperature and various historical temperatures.

The specific implementation process and principle of the above steps 201-203 can be referred to the detailed description of the above embodiment, which will not be repeated here.

Step 204: Determine a frame rate tolerance adjustment strategy corresponding to the current application according to the predicted temperature.

The frame rate tolerance may refer to the range by which the actual frame rate of the current application is allowed to deviate from the expected frame rate. It should be noted that the greater the frame rate tolerance, the greater the range by which the actual frame rate of the current application is allowed to deviate from the expected frame rate; the smaller the frame rate tolerance, the smaller the range by which the actual frame rate of the current application is allowed to deviate from the expected frame rate. It can be understood that the smaller the frame rate tolerance, the more stable the actual frame rate of the current application can be maintained.

For example, assuming the frame rate tolerance is 2fps and the expected frame rate is 90fps, when the actual frame rate of the current application is within the range of 88 to 92fps, it can be considered that the actual frame rate of the current application is normal; if the actual frame rate of the current application is not within the range of 88 to 92fps, it can be considered that the actual frame rate of the current application is abnormal.

As a possible implementation method, when the predicted temperature of the terminal device after a preset period of time is high, it means that if the terminal device continues to maintain the current frame rate, there may be a risk of overtemperature. Therefore, the current frame rate of the current application can be reduced, and the frame rate tolerance adjustment strategy can be determined to increase the current frame rate tolerance to prepare for the subsequent reduction of the current frame rate to prevent the frame rate tolerance from being too low and the current frame rate cannot be reduced. When the predicted temperature of the terminal device after the preset period of time is low, it means that the terminal device is currently operating in good condition and there is no risk of overtemperature. Therefore, the current frame rate of the current application can be kept unchanged, that is, there is no need to adjust the current frame rate at present, and the frame rate tolerance adjustment strategy can be determined to keep the current frame rate tolerance unchanged, or to reduce the current frame rate tolerance so that the frame rate of the application can be kept as stable as possible.

Furthermore, the reliability of stable frame scheduling can be further improved by setting a temperature threshold of the terminal device and using the temperature threshold as a standard to determine whether the terminal device has a risk of over-temperature. That is, in a possible implementation of the embodiment of the present application, the above step 204 may include:

When the predicted temperature is less than or equal to the safe temperature, the frame rate tolerance adjustment strategy is determined to reduce the current frame rate tolerance;

When the predicted temperature is greater than the safe temperature and less than or equal to the first warning temperature, the frame rate tolerance adjustment strategy is determined to keep the current frame rate tolerance unchanged;

When the predicted temperature is greater than the first warning temperature, the frame rate tolerance adjustment strategy is determined to increase the current frame rate tolerance.

The safety temperature may refer to the upper temperature limit that will not affect the performance of the terminal device. In other words, when the temperature of the terminal device is less than or equal to the safety temperature, the performance of the terminal device is in a relatively good state. In actual use, the specific value of the safety temperature may be set according to actual needs and specific application scenarios, and the embodiments of the present application do not limit this.

The first warning temperature in this embodiment may be the same as the first warning temperature in the aforementioned embodiment, which will not be described in detail here.

As a possible implementation method, if the predicted temperature is less than or equal to the safe temperature, it means that the temperature of the terminal device is still maintained at a good level after the preset time, and there is no need to adjust the current frame rate for a period of time. Therefore, the frame rate tolerance adjustment strategy can be determined to reduce the current frame rate tolerance, so that the frame rate of the current application is kept as stable as possible, further improving the frame rate stability; if the predicted temperature is greater than the safe stability and less than or equal to the first warning temperature, it means that although the temperature of the terminal device is maintained at a low level after the preset time, there may be a risk of excessive temperature in the future, that is, the current frame rate can be kept unchanged at present, but there may be a need to reduce the frame rate in a short period of time, so the frame rate tolerance adjustment strategy can be determined to maintain the current frame rate tolerance, so that the frame rate can be adjusted normally when the frame rate adjustment is needed; if the predicted temperature is greater than the first warning temperature, it means that the temperature of the terminal device may rise to a higher level after the preset time, that is, the current frame rate can be reduced at present, so as to slowly reduce the frame rate before the temperature of the terminal device is too high, therefore, the frame rate tolerance adjustment strategy can be determined to increase the current frame rate tolerance to ensure that the frame rate can be reduced normally.

As a possible implementation method, when the predicted temperature of the terminal device is high and the frame rate tolerance needs to be increased, the frame rate tolerance can be increased by different amplitudes according to the predicted temperature level of the terminal device, so that when a larger frame rate reduction amplitude is required, a higher frame rate tolerance can be achieved at the same time.

As an example, if the predicted temperature is greater than the first warning temperature and less than or equal to the second warning temperature, it means that the temperature of the terminal device after the preset time period may be high but within an acceptable range, so that the current frame rate can be reduced by a smaller first frame reduction amplitude, and the frame rate tolerance adjustment strategy can be determined to increase the current frame rate tolerance by a first preset value; if the predicted temperature is greater than the second warning temperature, it means that the temperature of the terminal device after the preset time period may be too high, so that the current frame rate can be reduced by a larger second frame reduction amplitude, and the frame rate tolerance adjustment strategy can be determined to increase the current frame rate tolerance by a second preset value.

It should be noted that the second preset value may be greater than the first preset value. In actual use, the specific values of the first preset value and the second preset value may be determined according to actual needs and specific application scenarios, and the embodiments of the present application do not limit this. For example, the first preset value may be 2fps, the second preset value may be 4fps, and so on.

Furthermore, when the frame rate adjustment strategy is determined by the frame stabilization decision model, the frame rate tolerance adjustment strategy can also be determined by the frame stabilization decision model to further improve the reliability and stability of the frame stabilization scheduling and further improve the display and operation fluency of the application. That is, in a possible implementation of the embodiment of the present application, the above-mentioned predicted temperature is determined by using a pre-trained frame stabilization decision model, and the above-mentioned frame stabilization decision model can also include a mapping relationship between the pre-trained temperature and the frame rate tolerance adjustment strategy; accordingly, the above-mentioned step 204 can include:

According to the predicted temperature and the mapping relationship between the temperature and the frame rate tolerance adjustment strategy, the frame rate tolerance adjustment strategy corresponding to the predicted temperature is determined as the frame rate tolerance adjustment strategy.

As a possible implementation method, a large amount of temperature data of a large number of terminal devices and the frame rate data and frame rate tolerance data of the current application can be obtained in advance, and the stable frame decision model can be trained until an accurate mapping relationship between temperature and frame rate adjustment strategy and an accurate mapping relationship between temperature and frame rate tolerance adjustment strategy are generated, that is, the stable frame decision model can be used for stable frame scheduling. That is to say, in an embodiment of the present application, after the current temperature of the terminal device, the historical temperature at each historical moment, the preset duration and the expected frame rate, and the current frame rate are input into the stable frame decision model, the stable frame decision model can calculate the predicted temperature of the terminal device after the preset duration based on these parameters, and then directly determine the frame rate tolerance adjustment strategy corresponding to the predicted temperature based on the predicted temperature and the mapping relationship between the pre-trained temperature and the frame rate tolerance adjustment strategy, and output it as the current frame rate tolerance adjustment strategy, so that the terminal device can adjust the current frame rate tolerance according to the frame rate tolerance adjustment strategy output by the stable frame decision model.

It should be noted that the pre-trained mapping relationship between temperature and frame rate tolerance adjustment strategy in the embodiment of the present application may include a large number of mapping relationships between temperature and frame rate tolerance adjustment strategies, that is, each different temperature may correspond to a different frame rate tolerance adjustment strategy, thereby achieving a more refined and accurate stable frame scheduling effect, and further improving the reliability and stability of stable frame scheduling.

Step 205: Determine a frame rate adjustment strategy corresponding to the current application according to the predicted temperature.

The specific implementation process and principle of the above step 205 can refer to the detailed description of the above embodiment, which will not be repeated here.

Step 206: Adjust the current frame rate tolerance corresponding to the current application according to the frame rate tolerance adjustment strategy.

In the embodiment of the present application, after the current frame rate tolerance adjustment strategy is determined, the current frame rate tolerance of the current application can be adjusted according to the frame rate tolerance adjustment strategy.

As a possible implementation method, if the frame rate adjustment strategy is to keep the current frame rate tolerance unchanged, the current frame rate tolerance can be kept unchanged; if the frame rate adjustment strategy is to reduce the current frame rate tolerance, the current frame rate tolerance can be reduced according to a preset amplitude; if the frame rate adjustment strategy is to increase the current frame rate tolerance, the current frame rate tolerance can be generated according to a preset amplitude.

As a possible implementation method, if the frame rate tolerance adjustment strategy is to reduce the current frame rate tolerance by a first preset value, the current frame rate tolerance can be reduced by the first preset value; if the frame rate tolerance adjustment strategy is to reduce the current frame rate tolerance by a second preset value, the current frame rate tolerance can be reduced by the second preset value.

Step 207: adjust the current frame rate according to the frame rate adjustment strategy.

The specific implementation process and principle of the above step 207 can refer to the detailed description of the above embodiment, which will not be repeated here.

The stable frame scheduling method provided in the embodiment of the present application predicts the temperature of the terminal device after a preset period of time based on multiple historical temperatures of the terminal device, so as to make an early judgment on the temperature condition of the terminal device, and slowly reduce the frame rate of the application in advance when it is predicted that the temperature may be too high, and adjust the frame rate tolerance of the application. This not only avoids the phenomenon of a cliff drop in the frame rate of the application, but also solves the problem of frame drops and jamming caused by a sudden drop in the frame rate, thereby improving the user experience and further improving the stability and reliability of the stable frame scheduling.

In a possible implementation form of the present application, since the processor frequency of the terminal device can directly affect the temperature of the terminal device, in order to maintain the temperature of the terminal device within a relatively stable range and prevent the terminal device from being overly hot and affecting performance, the processor frequency of the terminal device can be adjusted in advance when it is predicted that the terminal device is at risk of overheating. By controlling the temperature of the terminal device, the frame rate of the application can be maintained in a relatively optimal and stable state, thereby further improving the stability of stable frame scheduling and further improving the user experience.

The stable frame scheduling method provided in the embodiment of the present application is further described below in conjunction with FIG. 3 .

FIG3 shows a schematic flow chart of yet another stable frame scheduling method provided in an embodiment of the present application.

As shown in FIG3 , the stable frame scheduling method includes the following steps:

Step 301, obtaining the expected frame rate and current frame rate corresponding to the current application.

Step 302, obtaining the current temperature of the terminal device where the current application is located and the historical temperatures at multiple historical moments, wherein the historical moment refers to the display moment of multiple historical data frames before the current data frame.

Step 303, determining the predicted temperature of the terminal device after a preset time period according to the expected frame rate, the current temperature and various historical temperatures.

Step 304: Determine a frame rate adjustment strategy corresponding to the current application according to the predicted temperature.

The specific implementation process and principle of the above steps 301-304 can be referred to the detailed description of the above embodiment, which will not be repeated here.

Step 305: Determine a processor frequency adjustment strategy corresponding to the terminal device according to the predicted temperature.

In an embodiment of the present application, after determining the predicted temperature of the terminal device after a preset period of time, the operating status and temperature status of the terminal device in the future can be predicted in advance based on the predicted temperature, and then the processor frequency adjustment strategy corresponding to the terminal device can be determined based on the predicted temperature to prevent the terminal device from overheating and further improve the frame rate stability of the application.

As a possible implementation method, when the predicted temperature of the terminal device after a preset period of time is high, it means that the terminal device may be at risk of overheating, so the processor frequency corresponding to the terminal device can be reduced, that is, the processor frequency adjustment strategy can be determined to reduce the current processor frequency, so as to reduce the processor frequency in advance and prevent the temperature of the terminal device from continuing to rise; when the predicted temperature of the terminal device after a preset period of time is low, it means that the terminal device is currently operating in good condition and there is no risk of overheating, so the current processor frequency can be kept unchanged to ensure the display and operation smoothness of the application as much as possible.

It should be noted that in the embodiment of the present application, the reduction range of the processor frequency can be preset so that when the processor frequency adjustment strategy is to reduce the current processor frequency, the current processor frequency can be reduced by the preset frequency reduction range.

Furthermore, the reliability of stable frame scheduling can be further improved by setting a temperature threshold of the terminal device and using the temperature threshold as a standard to determine whether the terminal device has a risk of over-temperature. That is, in a possible implementation of the embodiment of the present application, the above step 305 may include:

When the predicted temperature is less than or equal to the second warning temperature, the processor frequency adjustment strategy is determined to keep the current processor frequency unchanged;

When the predicted temperature is greater than the second warning temperature, the processor frequency adjustment strategy is determined to reduce the current processor frequency.

The second warning temperature of this embodiment may be the same as the second warning temperature of the aforementioned embodiment, and will not be described in detail here.

As a possible implementation method, if the predicted temperature is less than or equal to the second warning temperature, it means that there is no risk of overheating of the terminal device after a preset period of time, so the processor frequency adjustment strategy can be determined to keep the current processor frequency unchanged to ensure the operating stability of the terminal device and the smoothness of application display and operation; if the predicted temperature is greater than the second warning temperature, it means that the temperature of the terminal device may be too high after the preset period of time, so the processor frequency adjustment strategy can be determined to reduce the current processor frequency, so that the temperature of the terminal device can be reduced to prevent the terminal device from being overheated.

It should be noted that in actual use, more warning temperatures can be set to divide the predicted temperature into more and more detailed temperature ranges, and different temperature ranges can correspond to different frequency reduction ranges, so as to schedule the processor frequency in a more detailed and accurate manner, further improving the reliability and stability of stable frame scheduling.

Furthermore, when the frame rate adjustment strategy is determined by the stable frame decision model, the processor frequency adjustment strategy can also be determined by the stable frame decision model to further improve the reliability and stability of the stable frame scheduling, and further improve the display and operation fluency of the application. That is, in a possible implementation of the embodiment of the present application, the above-mentioned predicted temperature is determined by using a pre-trained stable frame decision model, and the above-mentioned stable frame decision model can also include a mapping relationship between the pre-trained temperature and the processor frequency adjustment strategy; accordingly, the above-mentioned step 305 can include:

According to the predicted temperature and the mapping relationship between the temperature and the processor frequency adjustment strategy, the processor frequency adjustment strategy corresponding to the predicted temperature is determined as the processor frequency adjustment strategy.

As a possible implementation method, a large amount of temperature data of a large number of terminal devices and the frame rate data and processor frequency data of the current application can be obtained in advance, and the stable frame decision model can be trained until an accurate mapping relationship between temperature and frame rate adjustment strategy and an accurate mapping relationship between temperature and processor frequency adjustment strategy are generated, that is, the stable frame decision model can be used for stable frame scheduling. That is to say, in an embodiment of the present application, after the current temperature of the terminal device, the historical temperature at each historical moment, the preset duration and the expected frame rate, and the current frame rate are input into the stable frame decision model, the stable frame decision model can calculate the predicted temperature of the terminal device after the preset duration based on these parameters, and then directly determine the processor frequency adjustment strategy corresponding to the predicted temperature based on the predicted temperature and the mapping relationship between the pre-trained temperature and the processor frequency adjustment strategy, and output it as the current processor frequency adjustment strategy, so that the terminal device can adjust the current processor frequency according to the processor frequency adjustment strategy output by the stable frame decision model.

It should be noted that the pre-trained mapping relationship between temperature and processor frequency adjustment strategy in the embodiment of the present application may include a large number of mapping relationships between temperature and processor frequency adjustment strategies, that is, each different temperature may correspond to a different processor frequency adjustment strategy, thereby achieving a more detailed and accurate stable frame scheduling effect, and further improving the reliability and stability of stable frame scheduling.

Step 306: adjust the current frame rate according to the frame rate adjustment strategy.

The specific implementation process and principle of the above step 306 can be referred to the detailed description of the above embodiment, which will not be repeated here.

Step 307: Adjust the current processor frequency corresponding to the terminal device according to the processor frequency adjustment strategy.

In the embodiment of the present application, after the current processor frequency adjustment strategy is determined, the current processor frequency of the current application can be adjusted according to the processor frequency adjustment strategy.

The stable frame scheduling method provided in the embodiment of the present application predicts the temperature of the terminal device after a preset period of time based on multiple historical temperatures of the terminal device, so as to prejudge the temperature condition of the terminal device in advance, and when it is predicted that the temperature may be too high, slowly reduce the frame rate of the application in advance, and adjust the processor frequency corresponding to the terminal device, thereby not only avoiding the phenomenon of a cliff drop in the frame rate of the application, but also solving the problem of frame drops and jamming caused by a sudden drop in the frame rate, thereby improving the user experience, and by adjusting the processor frequency, the temperature of the terminal device can be reduced in time to prevent the temperature of the terminal device from being too high, thereby further improving the stability and reliability of the stable frame scheduling.

In a possible implementation form of the present application, the frame rate, frame rate tolerance and processor frequency of the application can also be adjusted simultaneously according to the temperature of the terminal device to further enhance the stability of the stable frame scheduling and further improve the user experience.

The stable frame scheduling method provided in the embodiment of the present application is further described below in conjunction with FIG. 4 .

As shown in FIG4 , the stable frame scheduling method includes the following steps:

Step 401, obtaining the expected frame rate and current frame rate corresponding to the current application.

Step 402, obtaining the current temperature of the terminal device where the current application is located and the historical temperatures at multiple historical moments, wherein the historical moment refers to the display moment of multiple historical data frames before the current data frame.

Step 403, determining the predicted temperature of the terminal device after a preset time period according to the expected frame rate, the current temperature and various historical temperatures.

Step 408: Adjust the current frame rate according to the frame rate adjustment strategy.

Step 409: Adjust the current processor frequency corresponding to the terminal device according to the processor frequency adjustment strategy.

As a possible implementation method, when performing stable frame scheduling for the current application, the frame rate adjustment strategy, frame rate tolerance adjustment strategy corresponding to the current application, and the processor frequency adjustment strategy corresponding to the terminal device can be determined simultaneously based on the predicted temperature of the terminal device after a preset period of time, and the current frame rate, current frame rate tolerance and current processor frequency can be adjusted respectively according to the determined frame rate adjustment strategy, frame rate tolerance adjustment strategy and processor frequency adjustment strategy.

It should be noted that when simultaneously determining the frame rate adjustment strategy, the frame rate tolerance adjustment strategy and the processor frequency adjustment strategy, the method of determining these three adjustment strategies can be the same as the method in the above embodiment. For example, the three adjustment strategies can be determined separately according to the temperature range of the preset temperature; or, the three adjustment strategies can be determined separately through a pre-trained stable frame decision model.

As an example, when determining the frame rate adjustment strategy, frame rate tolerance adjustment strategy and processor frequency adjustment strategy respectively by predicting the temperature range in which the temperature is located, the three adjustment strategies can be determined respectively by the correspondence between each temperature range and the frame rate adjustment strategy, frame rate tolerance adjustment strategy and processor frequency adjustment strategy in the following Table 1.
