Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1-1 is a top view of a mobile terminal according to an embodiment of the present invention, and fig. 1-2 is a side view of the mobile terminal according to the embodiment of the present invention. Referring to fig. 1-1 and 1-2, a temperature detection module 02 is disposed inside the mobile terminal case 00 at a position close to the processor 01. For example, the temperature detection module 02 may be a Negative Temperature Coefficient (NTC) thermistor. The temperature detection module 02 is used to detect the temperature inside the housing 00. Since the housing 00 of the mobile terminal is closer to the skin or palm of the user, the temperature detected by the temperature detection module 02 can reflect the actual feeling of the user on the temperature of the whole mobile terminal during the use process.
In the embodiment of the present invention, before the mobile terminal leaves the factory, the position for setting the temperature detection module 02 needs to be determined through a test. Specifically, the mobile terminal may be controlled to run the performance evaluation software to test the performance of the processor in the mobile terminal. The processor may include a Central Processing Unit (CPU) and a Graphics Processing Unit (GPU), among others. And main heating points of the mobile terminal are concentrated on the CPU and the GPU in the running process of the performance evaluation software. After the performance evaluation software runs for a period of time (for example, about 15 minutes), the heat distribution condition of the whole mobile terminal can be checked through the thermal imager, and the highest surface temperature point of the whole mobile terminal is determined as a heat source point. Finally, the temperature detection module 02 is arranged at the position corresponding to the heat source point inside the mobile terminal shell.
It should be noted that, in order to ensure the detection accuracy of the temperature detection module 02, the mobile terminal may further continue to run the performance evaluation software, compare the temperature detected by the temperature detection module 02 with the heat source value displayed by the thermal imager, and when the error between the temperature detected by the temperature detection module 02 and the heat source value is smaller than a certain threshold (e.g., 0.5 degrees), it may be determined that the temperature detection module 02 can accurately reflect the surface temperature of the mobile terminal, otherwise, the temperature detection module 02 needs to be replaced.
Fig. 2 is a flowchart of a temperature control method according to an embodiment of the present invention, where the method may be applied to the mobile terminal shown in fig. 1-1 or fig. 1-2, and referring to fig. 2, the method may include:
In the embodiment of the invention, the initial temperature of the mobile terminal can be obtained through the temperature detection module arranged inside the shell every time the mobile terminal is started (namely, every time the mobile terminal is started).
And 102, detecting whether the current temperature of the mobile terminal is greater than the target temperature in real time.
When the current temperature of the mobile terminal is greater than the target temperature, executing step 103; when the current temperature of the mobile terminal is not greater than the target temperature, the mobile terminal may perform step 104, step 108, or step 109 according to a specific range in which the detected current temperature is located.
In the running process of the mobile terminal, the current temperature of the mobile terminal can be obtained in real time through the temperature detection module, and whether the current temperature is greater than a preset target temperature or not is detected. The target temperature may be a preset temperature threshold in the mobile terminal, and when the current temperature of the mobile terminal is greater than the target temperature and a user touches the mobile terminal, the mobile terminal may bring a burning sensation to the user, which affects user experience.
For example, assuming that the target temperature is 45 degrees and the current temperature detected by the mobile terminal is 46 degrees, since the current temperature of the mobile terminal is greater than the target temperature, step 103 may be performed to avoid affecting the user experience.
When the current temperature of the mobile terminal is higher than the target temperature, the mobile terminal can determine that the skin of the user has a burning sensation when contacting the surface of the mobile terminal, and in order to ensure good user experience, the mobile terminal needs to adjust the upper limit frequency of the processor to the lowest frequency in the adjustable frequency list of the processor in time, so that the working frequency of the processor is limited to the maximum extent, and the temperature of the mobile terminal is reduced. Thereafter, the mobile terminal may proceed to step 102.
Further, the mobile terminal may further display a prompt message on the display interface, where the prompt message may be used to prompt the user that the current temperature of the mobile terminal is high, and prompt the user to close some applications to reduce the operating frequency of the processor.
And 104, when the temperature difference between the current temperature of the mobile terminal and the initial temperature is in a first temperature difference range, acquiring the average working frequency of the processor and the current upper limit frequency of the processor. Step 105 is performed.
Wherein the lower limit of the first temperature difference range is greater than 0. In the embodiment of the present invention, when the current temperature of the mobile terminal is not greater than the target temperature, the mobile terminal may further detect a temperature difference between the current temperature and the initial temperature, so as to determine a temperature change condition of the mobile terminal. When the temperature difference between the current temperature of the mobile terminal and the initial temperature is in the first temperature difference range, the mobile terminal may determine that the temperature of the mobile terminal is rising, and in order to control the temperature of the mobile terminal without affecting the performance of the mobile terminal, the mobile terminal may obtain the average operating frequency of the processor and the current upper limit frequency of the processor. The average working frequency can be an average value obtained by calculating after sampling the working frequency of the processor for multiple times after the mobile terminal determines that the temperature difference is within the first temperature difference range; the current upper limit frequency of the processor may refer to the highest frequency that can be achieved during the current operation of the processor, and the mobile terminal may adjust the upper limit frequency.
For example, assuming that the first temperature difference range is 2 degrees to 4 degrees, the initial temperature of the mobile terminal is 30 degrees, and the current temperature is 33 degrees, since the temperature difference between the current temperature of the mobile terminal and the initial temperature is 3 degrees, which is in the first temperature difference range, the mobile terminal may obtain the current average operating frequency of the processor, which may be 900 megahertz (MHz), for example, and the current upper limit frequency of the processor, which may be 1.3 gigahertz (GHz), for example.
When the frequency of the next stage is greater than the average operating frequency of the processor, step 106 may be performed; step 107 may be performed when the frequency of the next stage is not greater than the average operating frequency of the processor.
In the embodiment of the invention, when the mobile terminal is started, the adjustable frequency list of the processor can be obtained, and at least one adjustable upper limit frequency of the processor is recorded in the adjustable frequency list. After determining the current upper limit frequency of the processor, the mobile terminal may compare a frequency in a next stage of the adjustable frequency list to the current upper limit frequency of the processor. The frequencies in the adjustable frequency list may be arranged from high to low, so that the frequency of the next stage is the frequency with the smallest difference from the current upper limit frequency among the frequencies less than the current upper limit frequency.
For example, it is assumed that the adjustable frequency list of the processor acquired by the mobile terminal is shown in table 1, the current average operating frequency of the processor in the mobile terminal is 900MHz, and the current upper limit frequency of the processor is 1.3 GHz. As can be seen from table 1, the current upper limit frequency: the next order of frequency at 1.3GHz is: 1.1GHz, which is greater than the current average operating frequency of the processor of 900MHz, so that the mobile terminal can perform step 106. If the mobile terminal detects that the current average operating frequency of the processor is 1.2GHz, the mobile terminal may execute step 107 at this time because the frequency of the next stage, 1.1GHz, is less than the current average operating frequency.
TABLE 1
| Adjustable frequency | 1.5GHz | 1.3GHz | 1.1GHz | 900MHz | 700MHz | 500MHz |
And step 106, determining the frequency of the next stage as the updated upper limit frequency of the processor. Step 102 is performed.
When the frequency located at the next stage of the current upper limit frequency of the processor in the adjustable frequency list of the processor is greater than the average operating frequency of the processor, the mobile terminal may determine that the frequency of the next stage can meet the current operating requirement of the processor, and the operating performance of the mobile terminal is not affected, so the frequency of the next stage may be determined as the updated upper limit frequency of the processor. For example, the mobile terminal may adjust the upper frequency limit of the processor from 1.3GHz to 1.1 GHz.
Because the upper limit frequency of the processor is reduced by one level, and the reduced upper limit frequency is greater than the current average working frequency of the processor, the temperature rise condition of the mobile terminal can be effectively relieved, the phenomenon that the mobile terminal is jammed in operation can be avoided, and good user use smoothness and hand feeling of the surface temperature of the mobile terminal are guaranteed.
And step 107, keeping the current upper limit frequency of the processor unchanged. Step 102 is performed.
When the frequency in the next stage of the current upper limit frequency of the processor in the adjustable frequency list of the processor is not greater than the average operating frequency of the processor, the mobile terminal may determine that the frequency in the next stage may not meet the current operating requirement of the processor, so to avoid affecting the performance of the mobile terminal, the mobile terminal may keep the current upper limit frequency of the processor unchanged, and perform step 102, that is, continue to detect the current temperature of the mobile terminal in real time through the temperature detection module.
And 108, when the temperature difference between the current temperature of the mobile terminal and the initial temperature is larger than the upper limit of the first temperature difference range, determining the frequency of the next stage as the updated upper limit frequency of the processor. Step 102 is performed.
In the embodiment of the present invention, when the mobile terminal detects that the temperature difference between the current temperature and the initial temperature is greater than the upper limit of the first temperature difference range after step 102, it may be determined that the current temperature rises too fast, so that the frequency in the adjustable frequency list of the processor, which is located at the next stage of the current upper limit frequency of the processor, may be directly determined as the updated upper limit frequency of the processor, and the temperature rising speed of the mobile terminal may be slowed down.
For example, assuming that the first temperature difference range is 2 degrees to 4 degrees, and the upper limit of the first temperature difference range is 4 degrees, when the mobile terminal detects that the current temperature rises to 35 degrees, the upper limit frequency of the processor may be adjusted from 1.3GHz to 1.1GHz in order to slow down the temperature rise speed of the mobile terminal.
And step 109, acquiring the current upper limit frequency of the processor when the current temperature of the mobile terminal is detected to be in the preset low temperature range. Step 110 is performed.
The preset low-temperature range can be a lower temperature range preset in the mobile terminal, the lower limit of the preset low-temperature range is greater than the initial temperature of the mobile terminal, and the upper limit of the preset low-temperature range is less than the target temperature. When the mobile terminal detects that the current temperature is in the preset low temperature range after the step 102, it may be determined that the current temperature of the mobile terminal is low, and the upper limit frequency of the processor may be appropriately raised, so that the mobile terminal may first obtain the current upper limit frequency of the processor.
The frequency of the upper stage is the frequency with the smallest difference with the current upper limit frequency in the frequency list larger than the current upper limit frequency. Because the current temperature of the mobile terminal is smaller than the preset low-temperature range, the mobile terminal can determine that the temperature of the mobile terminal rises within a certain range and does not influence the user experience, so that the upper limit frequency of the processor can be increased by one level, and the performance of the mobile terminal is improved.
For example, assuming that the preset low temperature range is 31 degrees to 33 degrees, when the current temperature detected by the mobile terminal is 31 degrees and is in the preset low temperature range, if the current upper limit frequency of the processor is 1.3GHz and the adjustable frequency list of the processor is shown in table 1, the processor may select a frequency in the adjustable frequency list, which is one level above the current upper limit frequency of 1.3 GHz: the 1.5GHz limit is determined as the updated upper frequency of the processor.
It should be noted that, in the embodiment of the present invention, after the mobile terminal completes the adjustment of the upper limit frequency of the processor through the above step 103, step 106, step 107, step 108, or step 110, step 102 may be continuously performed, that is, the current temperature of the mobile terminal is continuously detected in real time, and the detected temperature is compared with the target temperature.
It should be further noted that, in the embodiment of the present invention, the processor in the mobile terminal may include a plurality of processing units, wherein each processing unit may be provided therein with a temperature sensor for detecting its own temperature. For example, an 8-core CPU may be divided into two CPU clusters, where one CPU cluster may include 4 large cores, and the other CPU cluster may include 4 small cores, where each CPU core is provided with a temperature sensor therein, and may detect the temperature of the CPU core.
In an optional implementation manner of the embodiment of the present invention, when the mobile terminal detects that the temperature difference between the current temperature and the initial temperature is in the first temperature difference range after step 102, referring to fig. 3, the temperature of the mobile terminal may be further controlled by adjusting the operating state of the processing unit. The method specifically comprises the following steps:
When the processor includes a plurality of processing units, executing step 112; when the processor does not include a plurality of processing units, namely the processor is a single-core processor, the operation is ended.
And step 112, detecting whether a processing unit which is not on-line exists in the plurality of processing units.
When there is a processing unit that is not on-line among the plurality of processing units, performing step 113; when there is no processing unit not on-line among the plurality of processing units, the operation is ended.
For example, assuming that the processor of the mobile terminal includes 8 processing units, wherein 4 processing units are in an online (on line) state, and the other 4 processing units are in an offline (off line) state, the mobile terminal may execute step 113.
And 113, detecting whether the temperature difference between the processing unit with the highest temperature in the processing units which are on line and the processing unit with the lowest temperature in the processing units which are not on line is in a second temperature difference range.
In the embodiment of the present invention, the mobile terminal may acquire the temperature of each processing unit through a temperature sensor provided in each processing unit. When the temperature difference between the processing unit with the highest temperature in the processing unit that has been brought online and the processing unit with the lowest temperature in the processing unit that has not been brought online is in the second temperature difference range, the mobile terminal may perform step 114; otherwise, the operation is ended. Wherein, the lower limit of the second temperature difference range is greater than 0, and the lower limit of the second temperature difference range may be greater than the lower limit of the first temperature difference range.
For example, assuming that the second temperature difference range is 10 degrees to 20 degrees, the temperature of the processing unit 1 with the highest temperature among the 4 processing units that have been brought on line is 70 degrees, and the temperature of the processing unit 6 with the lowest temperature among the processing units that have not been brought on line is 55 degrees. The mobile terminal may perform step 114 because the temperature difference between the processing unit 1 with the highest temperature and the processing unit 6 with the lowest temperature is 15 degrees, which is within the second temperature difference range.
When the temperature difference between the processing unit with the highest temperature in the processing unit that has been brought online and the processing unit with the lowest temperature in the processing unit that has not been brought online is in the second temperature difference range, in order to balance the temperatures of the respective processing units, the mobile terminal may turn off the processing unit with the highest temperature and turn on the processing unit with the lowest temperature. For example, the mobile terminal may adjust the processing unit 1 with the highest temperature to an offline state, and adjust the processing unit 6 with the lowest temperature to an on-line state.
Further, when the mobile terminal detects that the current temperature of the mobile terminal is within the preset low temperature range after the step 102, referring to fig. 4, the temperature of the mobile terminal may also be controlled by adjusting the operating state of the processing unit. The method specifically comprises the following steps:
When the processor includes a plurality of processing units, step 116 is performed; when the processor does not include a plurality of processing units, namely the processor is a single-core processor, the operation is ended.
When there is a processing unit that is not on-line among the plurality of processing units, performing step 117; when there is no processing unit not on-line among the plurality of processing units, the operation is ended.
The target processing unit is a processing unit which is closed by the mobile terminal in the process of temperature control. When there is a target processing unit in the offline processing units, execute step 118; and ending the operation when the target processing unit does not exist in the processing units which are not on line.
For example, assuming that the processing unit 1 is adjusted from the on-line state to the off-line state in step 114, the mobile terminal may determine the processing unit 1 as the target processing unit and execute step 118, i.e., restart the processing unit 1.
When the mobile terminal detects that the current temperature is lower than the initial temperature, the mobile terminal can determine that the temperature of the mobile terminal rises to a certain range and does not affect the user experience, so that the processing unit which is closed in the temperature control process before can be restarted to improve the performance of the mobile terminal.
It should be noted that, in the above embodiments of the present invention, the processor may include a CPU and a GPU, and the mobile terminal may adjust the frequencies of the two types of processors according to the adjustable frequency list of the CPU and the adjustable frequency list of the GPU respectively.
It should be further noted that the order of the steps of the temperature control method provided in the embodiment of the present invention may be appropriately adjusted, and the steps may also be increased or decreased according to the situation. For example, steps 111 to 114 may be performed in synchronization with step 104, and steps 115 to 118 may be performed in synchronization with step 109. Any method that can be easily conceived by those skilled in the art within the technical scope of the present disclosure is covered by the protection scope of the present disclosure, and thus, the detailed description thereof is omitted.
In summary, embodiments of the present invention provide a temperature control method, which can adjust and update an upper limit frequency of a processor in time when a temperature of a mobile terminal rises relative to an initial temperature at startup, so that the updated upper limit frequency is smaller than a current upper limit frequency and larger than an average working frequency of the processor, and therefore, a temperature rise speed of the mobile terminal can be effectively reduced without affecting performance of the mobile terminal, and the method has a good control effect on the temperature of the mobile terminal.
