Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
These and other aspects of embodiments of the invention will be apparent with reference to the following description and attached drawings. In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the ways in which the principles of the embodiments of the invention may be practiced, but it is understood that the scope of the embodiments of the invention is not limited correspondingly. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
The temperature control method is applied to the mobile terminal, such as a mobile phone, a tablet computer and the like. The mobile terminal is divided into a plurality of areas according to different holding positions, namely, the mobile terminal is divided into a plurality of different holding parts according to different postures of a user for holding the mobile terminal. The heating devices of the mobile terminal are distributed in the areas, a plurality of temperature sensors are arranged on the areas respectively and used for detecting the temperature of each position on the area, and the holding area of a user is identified by arranging the temperature sensors in each area of the mobile terminal.
Referring to fig. 1, a method for controlling a temperature of a mobile terminal according to a first embodiment of the present invention includes steps S11-S14.
And step S11, acquiring temperature information acquired by the temperature sensors of the areas, and determining the current area held by the hand of the user from the areas according to the temperature information.
In this embodiment, the surface of the mobile phone is divided into a plurality of areas for holding according to the gesture of the user holding the mobile terminal. For example, taking a cell phone as an example, the gestures of the user holding the cell phone include, but are not limited to: the mobile phone comprises a lower half part of the mobile phone, an upper half part of the mobile phone and a middle part of the mobile phone, wherein the lower half part, the upper half part and the lower half part of the mobile phone are respectively held by two hands. According to the holding gesture of the user, the mobile phone can be divided into an upper area, a middle area and a lower area. Main heating devices are reasonably distributed into the three areas, and for mobile terminals such as mobile phones and tablet computers, the devices with larger heating comprise: the system comprises a processor SOC, a loudspeaker PA chip, a display control chip, a charging chip, a radio frequency amplification circuit and the like. Preferably, the processor SOC is disposed in an upper region, the rf amplifier circuit and the display control chip are disposed in a middle region, the speaker PA chip is disposed in a lower region, and a charging chip is disposed in each of the upper region and the lower region.
In order to improve the accuracy of temperature detection of the respective zones, a plurality of temperature sensors are provided for each zone to detect the temperature of the respective position of the respective zone. Generally, the temperature of the hand-held area and the non-hand-held area will form a certain difference, so that the recognition model can be trained by the machine learning algorithm to detect the hand-held area, i.e. the current area held by the user's hand.
And step S12, determining the temperature of the current area according to the temperature information collected by the temperature sensor of the current area.
The temperature of the current zone is determined based on the temperature information collected by the temperature sensor in the current zone. Generally, the average value of the temperatures detected by the temperature sensors in the current area is taken as the temperature of the current area.
Step S13, determining whether the temperature of the current region is greater than a threshold temperature.
Step S14, when the temperature of the current region is greater than a threshold temperature, limiting the performance of the heat generating device in the current region to reduce the heat generation of the device in the current region.
The threshold temperature may be set in advance in the system of the terminal, and may be set to 36 ℃, for example. It will be appreciated that the threshold temperature may be determined based on statistical limitations of perceived temperature that may be tolerated by different users, i.e., a user may feel uncomfortable and experience a poor experience above the threshold temperature.
When the temperature of the current area is higher than the threshold temperature, the performance of the heat generating device in the current area is limited to reduce the heat generation of the heat generating device. Different heat generating devices may limit performance in different ways, for example, for a processor SOC by reducing the operating frequency of its CPU and/or GPU, i.e. by sacrificing some of the performance to reduce heat generation. For the charging chip, the charging power can be reduced by reducing the charging reduction current, so that the heat generation is reduced. For the screen control chip (screen IC), the limited way is to reduce the backlight brightness, so as to reduce the heat generation of the screen control chip. For the speaker PA chip, it is a limiting way to reduce the power of the speaker PA chip, specifically, the power of the speaker power amplifier, so as to reduce the heat generation of the speaker PA chip.
This implementation provides a temperature subregion's thinking, combines the gesture of gripping in the user use terminal process, divides mobile terminal into a plurality of regions, and distributes mobile terminal's main device that generates heat to these a plurality of regions of arranging in a dispersed manner to restrict the performance that the user held regional device through this temperature control method, reduce and generate heat, thereby can not influence the performance in other warm districts when obtaining better temperature rise experience, obtain better user experience.
Fig. 2 is a method for controlling a temperature of a mobile terminal according to a second embodiment of the present invention, and fig. 3 is a schematic diagram illustrating a region division of the mobile terminal according to the second embodiment of the present invention. As shown in fig. 3, the mobile terminal is divided into three regions, namely a first region 31, a second region 32 and a third region 33, the first region 31, the second region 32 and the third region 33 are respectively located at the upper part, the middle part and the lower part of the back surface of the mobile terminal, the first region 31 is provided with a processor SOC and a first charging chip, the second region 32 is provided with a radio frequency amplifying circuit and a display control chip, and the third region 33 is provided with a speaker PA chip and a second charging chip. The temperature control method includes steps S21-S27.
And step S21, acquiring temperature information acquired by the temperature sensors of the areas, and determining the current area held by the hand of the user from the areas according to the temperature information.
Further, the step of determining a current area of the hand grip of the user from the plurality of areas according to the temperature information may include:
and calculating the temperature difference value of each region and the adjacent region, training a recognition model through a machine learning algorithm according to the calculated temperature difference value, and detecting the current region held by the hand of the user.
The temperature of the hand-held area and the temperature of the non-hand-held area form a certain difference, so that the recognition model can be trained through a machine learning algorithm, and the hand-held position can be detected.
Step S22, when the current area is the first area, determining the temperature of the first area according to the temperature information collected by the temperature sensor of the first area.
The current area of the hand of the user is the first area, which indicates that the user is holding the upper half of the mobile terminal with one hand. At least one temperature sensor can be respectively arranged at the middle position and the position corresponding to the mobile terminal frame area in the first area, and the temperature of the first area is determined according to the temperature detected by each temperature sensor on the first area. In a specific implementation, the temperature of the first region may be an average value of temperatures detected by the temperature sensors in the region.
Step S23, when the temperature of the first region is greater than the threshold temperature, decreasing the operating current of the first charging chip, and decreasing the operating frequency of the processor SOC.
Specifically, in step S23, the step of reducing the current of the first charging chip and the operating frequency of the processor SOC may include:
judging whether the temperature of the first area is greater than a first preset temperature, wherein the first preset temperature is greater than the threshold temperature;
when the temperature of the first area is higher than a first preset temperature, closing the first charging chip, and reducing the working frequency of the processor SOC to a first threshold frequency;
when the temperature of the first area is less than or equal to the first preset temperature, reducing the working current of the first charging chip to a first threshold current, and reducing the working frequency of the processor SOC to a second threshold frequency.
When a user holds the first area by hand and the temperature of the first area is higher than a first preset temperature, it is indicated that the temperature of the first area is far higher than a threshold temperature, and the cooling requirement of the first area is not sufficiently met by reducing the working current of the first charging chip, so that the first charging chip of the first area needs to be turned off, that is, the first charging chip does not work, and only the second charging chip works. At the same time, the operating frequency of the processor SOC is reduced to the first threshold frequency.
When the temperature of the first area is lower than a first preset temperature and higher than a threshold temperature, the working current of the first charging chip is reduced to a first threshold current, and the working frequency of the processor SOC is reduced to a second threshold frequency. At this time, the second charging chip operates according to the operating current in the normal state.
It should be noted that, in this embodiment, the mobile terminal is provided with two charging chips, that is, the first charging chip and the second charging chip, and the two charging chips may be used simultaneously or separately, and when the two charging chips are used simultaneously, the charging rate may be increased.
It is understood that the first threshold frequency and the second threshold frequency are lower than the frequency of the processor SOC chip in the normal state. In specific implementation, the first threshold frequency and the second threshold frequency may be set according to actual conditions, and both of them may be set to the same value or different values.
Step S24, when the current area is the second area, determining the temperature of the second area according to the temperature information collected by the temperature sensor of the second area.
And step S25, when the temperature of the second area is greater than the threshold temperature, reducing the radio frequency emission power of the radio frequency amplifying circuit and reducing the backlight brightness of the display control chip.
The current area of the hand holding of the user is the second area, which indicates that the user is holding the middle part of the mobile terminal with one hand. At least one temperature sensor can be respectively arranged at the middle position and the position corresponding to the mobile terminal frame area in the second area, and the temperature of the second area is determined according to the temperature detected by each temperature sensor on the second area.
When the temperature of the second area is higher than the threshold temperature, the radio frequency emission power of the radio frequency amplification circuit is reduced, and the backlight brightness of the display control chip is reduced, so that the heating of the second area is reduced, and other areas work normally.
In specific implementation, the radio frequency transmission power of the radio frequency amplifying circuit can be directly reduced to a preset constant value, or gradually reduced to the preset constant value. The backlight brightness of the display control chip can also be directly reduced to a preset brightness value or gradually reduced to the preset brightness value.
Step S26, when the current area is the third area, determining the temperature of the third area according to the temperature information collected by the temperature sensor of the third area.
And step S27, when the temperature of the third area is greater than the threshold temperature, reducing the working current of the second charging chip and reducing the power of the PA chip of the loudspeaker.
The current area of the hand of the user is the third area, which indicates that the user is holding the lower part of the mobile terminal with one hand. And when the temperature of the third area is judged to be greater than the threshold temperature, reducing the working current of the second charging chip and reducing the power of the PA chip of the loudspeaker.
Further, in step S27, the step of reducing the operating current of the second charging chip and reducing the power of the speaker PA chip may include:
judging whether the temperature of the third area is greater than a second preset temperature, wherein the second preset temperature is greater than the threshold temperature;
when the temperature of the third area is higher than the second preset temperature, the second charging chip is turned off, and the power of the PA chip of the loudspeaker is reduced to a first threshold power;
and when the temperature of the third area is less than or equal to the second preset temperature, reducing the working current of the second charging chip to a second threshold current, and reducing the power of the PA chip of the loudspeaker to a second threshold power.
It can be understood that the second preset temperature may be the same as the first preset temperature, or may be a different value, which may be set according to actual requirements. When a user holds the third area by hand and the temperature of the third area is higher than the second preset temperature, it is indicated that the temperature of the third area is far higher than the threshold temperature, and the cooling requirement of the first area is not satisfied enough by reducing the working current of the second charging chip, so that the second charging chip of the second area needs to be turned off, that is, the second charging chip does not work, and only the first charging chip works. At the same time, the power of the speaker PA chip is reduced to a first threshold power.
It will be appreciated that the first and second threshold powers are lower than the power of the loudspeaker PA chip in the normal state. In specific implementation, the first threshold power and the second threshold power may be set according to actual conditions, and both may be set to the same value or different values.
In this embodiment, when a user holds the first area or the third area of the mobile terminal, whether the temperature of the current holding area is greater than the corresponding preset temperature is determined, and if yes, the charging chip of the current holding area is controlled to be turned off, so that the temperature of the area is reduced to the maximum extent, the temperature felt by the hand of the user is appropriate, and the user experience is improved.
Further, in another embodiment of the present invention, when it is determined that the portion held by the user is two areas, that is, when the user holds the mobile terminal laterally, the two hands hold both ends of the mobile terminal simultaneously, that is, when the current area held by the user's hands is the first area and the third area, the operating currents of the first charging chip and the second charging chip are reduced, the operating frequency of the processor SOC is reduced, and the power of the speaker PA chip is reduced. In specific implementation, the steps of reducing the working current of the first charging chip and the second charging chip, reducing the working frequency of the processor SOC, and reducing the power of the speaker PA chip include:
judging whether the temperature of the first area is greater than a third preset temperature or not, and judging whether the temperature of the third area is greater than a fourth preset temperature or not, wherein the third preset temperature and the fourth preset temperature are both greater than the threshold temperature;
when the temperature of the first area is higher than the third preset temperature and the temperature of the third area is lower than or equal to the fourth preset temperature, turning off the first charging chip, reducing the working frequency of the processor SOC to a third threshold frequency, reducing the working current of the second charging chip to a third threshold current, and reducing the power of the loudspeaker PA chip to a third threshold power;
when the temperature of the first area is less than or equal to the third preset temperature and the temperature of the third area is greater than the fourth preset temperature, reducing the working current of the first charging chip to a fourth threshold current, reducing the working frequency of the processor SOC to a fourth threshold frequency, turning off the second charging chip, and reducing the power of the loudspeaker PA chip to the fourth threshold power;
when the temperature of the first area is higher than the third preset temperature and the temperature of the third area is higher than the fourth preset temperature, the working current of the first charging chip is reduced to a fifth threshold current, the working frequency of the processor SOC is reduced to a fifth threshold frequency, the working current of the second charging chip is reduced to a fifth threshold current, the power of the loudspeaker PA chip is reduced to a fifth threshold power, the fifth threshold current is smaller than the third threshold current and smaller than the fourth threshold current, the fifth threshold frequency is smaller than the third threshold frequency and smaller than the fourth threshold frequency, and the fifth threshold power is smaller than the third threshold power and smaller than the fourth threshold power.
It should be noted that, here, the third preset temperature may be the same as the first preset temperature, and the fourth preset temperature may be the same as the second preset temperature. In this embodiment, the heat generating devices in the respective areas are controlled as follows:
in case one, when the temperature of the first area is higher than a third preset temperature and the temperature of the third area is between the threshold temperature and a fourth preset temperature, the first charging chip in the first area is turned off, the operating circuit of the second charging chip is reduced to a third threshold current, the operating frequency of the processor SOC is reduced to a third threshold frequency, and the power of the speaker PA chip is reduced to a third threshold power. Namely, the energy of the heat generating devices in the first area and the third area is limited at the same time, and the energy of the heat generating devices in the first area is limited to the maximum extent.
And in case two, when the temperature of the first area is between the third preset temperature and the threshold temperature and the temperature of the third area is higher than the fourth preset temperature, the second charging chip is turned off, the working circuit of the first charging chip is reduced to a fourth threshold current, the working frequency of the processor SOC is reduced to a fourth threshold frequency, and the power of the loudspeaker PA chip is reduced to a fourth threshold power. Namely, the energy of the heating devices in the first area and the third area is limited at the same time, and the energy of the heating devices in the third area is limited to the maximum extent.
And in a third situation, when the temperature of the first area is greater than a third preset temperature and the temperature of the third area is greater than a fourth preset temperature, it is indicated that the temperatures of the first area and the third area are much greater than a threshold temperature, and energy limitation needs to be performed on the heating devices in the two areas to a greater extent. In the third case, the current of the charging chips in the first area and the third area is reduced to the fifth threshold current, and the fifth threshold current is smaller than the third threshold current and the fourth threshold current, i.e., the energy is limited to a greater extent.
In specific implementation, the third threshold frequency and the fourth threshold frequency may be set according to actual conditions, and both of them may be set to the same value or different values. The third threshold power and the fourth threshold power may also be set according to actual conditions, and both may be set to the same value or different values.
