Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present application are provided.

First embodiment

Referring to fig. 3, fig. 3 is a schematic flow chart of the first embodiment of the present application. The temperature control method comprises the following steps:

step S110, a first temperature value of the embedded negative temperature coefficient NTC and a second temperature value of the main board NTC are obtained, optionally, the embedded NTC is disposed on the rear case of the mobile terminal, and the main board NTC is disposed on the main board of the mobile terminal.

In this embodiment, a first temperature value provided by an embedded NTC disposed on a rear shell of a mobile terminal is obtained, and it can be understood that the embedded NTC, as disposed on the rear shell of the mobile terminal, can directly contact with the skin of a user of the mobile terminal, so as to directly obtain a temperature on the skin of the user contacting the mobile terminal, that is, the first temperature value is a temperature on the skin of the user; and acquiring a second temperature value provided by a main board NTC arranged on a main board of the mobile terminal, wherein the main board NTC can directly acquire the temperature on the hardware of the mobile terminal due to the main board arranged on the mobile terminal, namely the second temperature value is the temperature on the hardware of the mobile terminal.

It should be noted that the temperature can be obtained and controlled by the thermal frame in this embodiment.

It should be noted that, the NTC main board is disposed on the main board of the mobile terminal, and the purpose of the NTC main board is to protect the hardware, so as to avoid damage to the hardware due to over-high temperature, and the user experience when using the mobile terminal is not considered, it can be understood that the hardware can normally operate in an environment with higher temperature, and the higher temperature is higher than the temperature that the user can feel hot, so that even when the user has sensed that the mobile terminal has sensed hot, the temperature does not affect the hardware, and no measures are taken to solve the problem that the user feels hot, so that the temperature continues to rise. The embedded NTC is focused on solving the problem that the user feels hot, and specifically the solving process is as follows:

step S120, calculating a temperature difference value between the first temperature value and the second temperature value;

step S130, performing a temperature-related control operation based on the temperature difference and at least one preset strategy.

In the embodiment, the temperature difference between the first temperature value and the second temperature value is calculated, namely the temperature difference between the temperature on the mobile terminal hardware and the temperature which can be sensed by the skin of the user is determined; and executing temperature-related control operation according to the temperature difference and at least one preset strategy.

Optionally, the preset strategy includes a preset graded response temperature control strategy, and the preset graded response temperature control strategy includes:

and carrying out graded response on the temperature difference.

In this embodiment, different temperature difference values have different response strategies, that is, the preset graded response temperature control strategy performs graded response on different temperature difference values. It is understood that the degree of limitation of heat generation may be smaller when the temperature difference is smaller, and may be larger when the temperature difference is larger.

Optionally, the step of responding to the temperature difference comprises at least one of:

if the temperature difference belongs to a first temperature difference area, starting a first-level response;

if the temperature difference belongs to a second temperature difference area, starting a second-level response;

and if the temperature difference belongs to a third temperature difference area, starting a third-level response.

In this embodiment, the classification is performed according to the magnitude of the temperature difference, and optionally, if the temperature difference belongs to the first temperature difference region, a first-level response is started; if the temperature difference belongs to a second temperature difference area, starting a second-level response; and if the temperature difference belongs to the third temperature difference area, starting a third-level response.

For the first temperature difference region, the second temperature difference region and the third temperature difference region, the region division is based on different preset temperature thresholds, for example, the first temperature difference region is divided into 10 to 20 degrees, the second temperature difference region is divided into 20 to 30 degrees and the third temperature difference region is divided into 30 to 40 degrees by preset temperature thresholds of 20 degrees, 30 degrees and 40 degrees, the preset temperature thresholds can be set as required, and the embodiment is not particularly limited; optionally, the first level response, the second level response and the third level response correspond to different degrees of performance limitation of the mobile terminal, for example, the first level response corresponds to 10% of the performance limitation, the second level response corresponds to 20% of the performance limitation, and the third level response corresponds to 30% of the performance limitation. It will be appreciated that restricting performance affects user usage to a greater extent, and to a lesser extent. Therefore, the response to different temperature difference values is divided into the first level response, the second level response and the third level response, so that the influence of the response process on the use process of a user is reduced, and the user experience is improved.

In addition, the preset strategy comprises a preset temperature compensation temperature control strategy, and the executing of the temperature-related control operation based on the temperature difference value and at least one preset strategy comprises:

step a, if the temperature difference value is larger than a preset temperature difference value threshold value, executing temperature-related control operation based on a preset temperature compensation temperature control strategy.

In this embodiment, if the acquired temperature value provided by the NTC is an abnormal temperature value, for example, the second temperature value of the main board NTC is abnormal, that is, if the temperature difference value is greater than the preset temperature difference value threshold, it is indicated that a main board NTC fault occurs, and it needs to be noted that when the NTC fault (damage or abnormal connection) occurs, an abnormally high temperature value is acquired, so that the mobile terminal enters high-temperature protection; and for the embedded NTCs, a plurality of embedded NTCs are arranged on the rear shell of the mobile terminal, and even if a single embedded NTC fails, the use of other embedded NTCs is not affected, so that the normal control of the temperature can be ensured. It can be understood that the mode of jointly controlling the temperature through the multiple embedded NTCs and the main board NTC avoids the mobile terminal from entering high-temperature protection by mistake, thereby avoiding the influence on the normal use of the user.

And for the fault condition of the NTC of the main board, ignoring the second temperature value, and executing temperature-related control operation through the first temperature value and a preset temperature compensation temperature control strategy. Optionally, when the NTC of the motherboard has a fault, directly comparing the magnitude of the first temperature value with a preset temperature threshold, and if the first temperature value is greater than the preset temperature threshold, executing a temperature-related control operation based on a preset temperature compensation temperature control strategy; and/or if the first temperature value is smaller than or equal to the preset temperature threshold, not executing temperature-related control operation based on a preset temperature compensation temperature control strategy, namely the first temperature value is in a normal use range. Alternatively, the preset temperature threshold may be a temperature at which the user feels hot, for example, the preset temperature threshold is 55 degrees, and it should be noted that the user may continuously touch an object at 55 degrees, but may feel hot.

It should be noted that, even though the first temperature value obtained by the embedded NTC is lower than the second temperature value obtained by the NTC of the main board at the same time, the temperature difference between the first temperature value and the second temperature value is smaller than the temperature difference between the temperature when the hardware is damaged due to high temperature and the temperature when the user feels hot, and therefore, the hardware is not damaged by performing the temperature-dependent control operation only through the first temperature value.

Optionally, the preset temperature compensation temperature control strategy includes:

and if the main board NTC fault is determined and/or the first temperature value is smaller than or equal to the preset temperature value threshold, the temperature-related control operation is not executed.

In this embodiment, if it is determined that the NTC of the motherboard is faulty and/or the first temperature value is less than or equal to the preset temperature value threshold, the temperature-related control operation is not performed; and/or if the first temperature value is greater than the preset temperature value, executing temperature-related control operation.

Optionally, the first temperature value comprises an ear temperature value and/or a hand temperature value.

In this embodiment, the first temperature value obtained by the embedded NTC includes an ear temperature value and/or a hand temperature value. It can be understood that the ear temperature value is a temperature value of the ear of the user, and likewise, the hand temperature value is a temperature value of the hand of the user.

For the ear temperature value, the embedded NTC is disposed at a position where the ear temperature can be detected, and it can be understood that when the application scenario of the mobile terminal is that a user makes a call, an earphone of the mobile terminal may contact with the ear of the user, and therefore, the embedded NTC for detecting the ear temperature of the user is disposed at the earphone position of the rear case of the mobile terminal.

For the hand temperature value, the embedded NTC is arranged at a position where the temperature of the hand can be detected, and it can be understood that when the application scene of the mobile terminal is that the user erects the screen for holding (for example, the user uses the mobile terminal to browse a website), two side surfaces of the mobile terminal can contact with the fingers of the user, so that the embedded NTC for detecting the temperature of the hand of the user is arranged at the position of the side surface of the rear shell of the mobile terminal; when the application scene of the mobile terminal is a user holding across a screen (e.g., the user playing a game using the mobile terminal), the upper and lower portions of the mobile terminal may contact with the user's fingers or palm, and thus, the embedded NTC for detecting the temperature of the user's hand is disposed at the upper and/or lower portion of the rear case of the mobile terminal.

The embedded NTC set by the setting mode can acquire a hand temperature value or an ear temperature value of a user.

Optionally, the temperature dependent control operation comprises at least one of:

limiting the core frequency of a central control unit (CPU) of the mobile terminal, limiting the using number of the CPU of the mobile terminal, limiting the magnitude of the charging current, limiting the brightness value of the backlight brightness, disabling the flash lamp and not responding to the temperature difference.

In the present embodiment, the temperature-related control operation is related to an influence factor that causes a large amount of heat generation of the mobile terminal, and it can be understood that the influence factor includes a core frequency, a use amount, a charging current, a backlight, a flash lamp, and the like of a CPU (Central Processing Unit) of the mobile terminal. Optionally, the temperature-dependent control operation includes limiting a core frequency of a CPU of the mobile terminal, limiting a number of CPUs used in the mobile terminal, limiting a magnitude of the charging current, limiting a brightness value of the backlight brightness, disabling the flash, and not responding to the temperature difference. Optionally, the core frequency of the CPU of the mobile terminal is limited, the number of CPUs of the mobile terminal is limited, the magnitude of the charging current is limited, the brightness value of the backlight brightness is limited, and the temperature-related control operation corresponding to the flash is disabled, which aims to cool down the mobile terminal. For example, the core frequency of the CPU of the mobile terminal is limited to 90% of the core frequency, the core number of the CPU of the mobile terminal is limited to 50% of the core number, the charging current is limited to 90% of the original charging current, the backlight is limited to 80% of the original backlight, and the flash lamp is disabled.

In this embodiment, by obtaining a first temperature value of an embedded negative temperature coefficient NTC and a second temperature value of a main board NTC, optionally, the embedded NTC is disposed on a rear shell of the mobile terminal, and the main board NTC is disposed on a main board of the mobile terminal; calculating a temperature difference between the first temperature value and the second temperature value; and executing temperature-related control operation based on the temperature difference value and at least one preset strategy. According to the embodiment, the cooling opportunity is determined through the temperature difference value, and the temperature-related control operation is executed through the preset strategy and the temperature difference value, so that the cooling purpose is realized, and the accuracy of the mobile terminal in controlling the cooling opportunity during cooling is improved.

It should be noted that the temperature can be obtained and controlled by the thermal frame in this embodiment.

It should be noted that, the NTC30 is disposed on the main board of the mobile terminal, and the purpose of the NTC30 is to protect the hardware, so as to avoid damage to the hardware due to over-high temperature, regardless of the user's experience when using the mobile terminal, it can be understood that the hardware can normally operate in an environment with higher temperature, which is higher than the temperature that the user can feel hot, so that even when the user has sensed that the mobile terminal has sensed hot, the temperature does not affect the hardware, and no measures are taken to solve the problem that the user feels hot, which results in the temperature continuing to rise. While the embedded NTC20 is focused on solving the problem of the user feeling scalding.
