Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a mobile terminal charging control method according to an exemplary embodiment, and as shown in fig. 1, the mobile terminal charging control method is used in a terminal and includes the following steps.
In step S13, temperature information of charging modules corresponding to a plurality of charging areas of the mobile terminal is obtained, and the plurality of charging areas are divided according to distribution information of heat dissipation areas of the mobile terminal and distribution information of the charging modules of the mobile terminal.
In step S14, based on the temperature information of the charging module in the first charging region, the region temperature of the first charging region, which is any one of the plurality of charging regions, is determined.
In step S15, in the case where the region temperature is greater than or equal to the first temperature threshold, the temperature information of the charging module in the first charging region is adjusted so that the temperature information is less than the first temperature threshold.
For example, in step S13, in some usage scenarios, the CPU, WIFI and other functional modules inside the mobile terminal need to perform continuous operation, which may cause the temperature of the corresponding area to increase, and when in a specific application scenario, for example, the mobile terminal runs a game, performs high-frequency website browsing, and long-time video playing, the corresponding functional module may rapidly increase in temperature, and be conducted to the mobile terminal housing, which causes the device to burn. Therefore, a heat dissipation element (such as a graphite heat dissipation film, a VC vapor chamber, etc.) made of a special material is generally disposed in a corresponding area of the functional module of the mobile terminal to cover the corresponding functional module, so as to ensure that the functional module can quickly dissipate heat to avoid abnormal local temperature rise during operation. For example, to ensure the heat dissipation effect, a coverage area of the heat dissipation element is generally set to be greater than or equal to that of a single functional module, and a corresponding area of each functional module is provided with a corresponding heat dissipation element, so that the heat dissipation elements are not affected before each other, and are not connected with each other. Optionally, for the functional modules with smaller area, a heat dissipation area can be formed with the adjacent functional modules, and a heat dissipation element is correspondingly arranged to dissipate heat of the functional modules, but at the moment, the area of the heat dissipation element cannot exceed a preset value, and meanwhile, in order to avoid the situation that the functional modules conduct heat mutually, heat dissipation is insufficient or even impossible, the number of the functional modules correspondingly covered by the heat dissipation element is usually not more than three. For example, when in practical application, the CPU and the WIFI function module of the mobile phone need to cooperate with each other, and usually in the functional circuit, the CPU and the WIFI function module are arranged at a relatively close position, and at this time, a relatively large heat dissipation element can be arranged to cover the two function modules to dissipate heat together, so as to ensure a good heat dissipation effect.
It is understood that, in order to make the functional circuits corresponding to the charging circuit and the functional module not affected each other, the functional circuits corresponding to the charging circuit and the functional module are disposed at different levels inside the mobile terminal. In general, the internal circuit of the mobile terminal adopts a double-layer motherboard, the charging circuit can be arranged on a second-layer motherboard which is close to the mobile terminal and is close to the shell, the functional circuit is arranged on a first-layer motherboard which is close to the display screen of the mobile terminal, and the two control circuits are separated by using a separation element to prevent signal interference. The main heating unit in the charging circuit of the mobile terminal is a charging IC module, the charging IC has a charging management function, different electric energy (usually expressed as current, voltage and power) input into the mobile terminal can be converted into rated electric energy (rated current, rated voltage and rated power) allowed by a battery of the mobile terminal through an electric energy regulating loop, and different charging ICs have different functions, so that different charging requirements of users are realized.
The mobile terminal comprises a plurality of charging circuits, one or more charging modules are arranged in each charging circuit, charging ICs (integrated circuits) can work independently of each other, charging of the same battery is not affected, and the charging ICs are arranged at different positions of the charging circuits so as to prevent local temperature abnormality caused by centralized setting of the charging ICs. For example, in order to prevent the situation that the mobile terminal is affected by the use of the user due to the heat generated by the charging IC and the heat generated by the functional module acting together on the mobile terminal, the charging IC and the functional module are generally set to correspond to each other and act on a local position of the mobile terminal housing together, when the local temperature reaches the first temperature threshold, the input current of the charging IC can be reduced, and if necessary, the charging IC with higher corresponding heat can be turned off, so that the local temperature of the mobile terminal is restored to the normal heat generating state. Therefore, according to the areas divided by the heat dissipation elements, the corresponding charging circuits are arranged at the corresponding positions of each heat dissipation element, so that the same heat dissipation element can dissipate heat for the charging circuits and the functional circuits at the same time, and the heat dissipation efficiency is ensured. It can be understood that at this time, the corresponding position of each functional module is provided with a charging IC, and the position covered by each charging IC represents a charging area, and the coverage area of each charging area may be consistent with the area of the heat dissipation element, so that the plurality of heat dissipation areas at this time are corresponding plurality of charging areas.
Optionally, referring to fig. 2, fig. 2 is a flowchart of a charging area dividing method according to an exemplary embodiment of the present disclosure, and before the step S13, the method further includes:
in step S11, according to the heat dissipation area distribution information, heat dissipation areas corresponding to the plurality of charging modules are obtained.
In step S12, the charging areas are divided according to the heat dissipation areas corresponding to the plurality of charging modules, so as to obtain a plurality of charging areas, wherein the charging modules corresponding to the same heat dissipation area are divided into the same charging area.
It can be understood that the charging module may be a charging IC, and is limited by each hardware module (e.g. a battery module, a camera module, and a receiver module) in the internal circuit of the mobile terminal, where the location of each charging IC is generally fixed, so that the charging area needs to be divided according to the distribution of the charging module and the heat dissipation area. For example, the distribution of the area areas corresponding to the plurality of charging ICs and the heat dissipation area is compared to determine the heat dissipation area corresponding to each charging IC, and in general, the coverage area corresponding to the heat dissipation area is larger than that of a single charging IC, so that the situation that the same heat dissipation area covers different charging ICs is easy to occur, and at this time, the charging ICs in the same heat dissipation area are divided into the same charging area.
Optionally, the area ratio of each charging IC in each heat dissipation area may be determined according to the distribution situation of the plurality of charging ICs and the plurality of heat dissipation areas, so that the area ratio of each charging IC in each heat dissipation area may be obtained, for example, the area ratio situation shown in the following ratio correspondence table:
CPU heat dissipation area | WIFI heat dissipation area | Heat dissipation area of operation module | |
Charging IC1 | 40% | 10% | 0 |
Charging IC2 | 35% | 20% | 10% |
Charging IC3 | 0 | 20% | 40% |
Charging IC4 | 0 | 50% | 20% |
... | ... | ... | ... |
For example, taking the above-mentioned duty ratio correspondence table as an example, if the duty ratio threshold is determined to be 30%, if the duty ratio of the charging IC1 and the charging IC2 in the CPU heat dissipation area reach the threshold, the charging IC1, the charging IC2 and the CPU heat dissipation area are divided into the same charging area, the duty ratio of the charging IC3 in the operation module heat dissipation area is 40%, and if no other charging IC in the operation module heat dissipation area reaches the threshold, the charging IC3 and the operation module heat dissipation area are divided into the same charging area.
It can be understood that the charging areas obtained by dividing the charging circuit of the mobile terminal according to the steps include a charging IC and a functional module, where the charging IC and the functional module are main heating units of the mobile terminal, so that the charging area at this time can be understood as a main heating area of the mobile terminal, and the internal circuit of the mobile terminal heats up to enable the corresponding position of the housing to continuously raise temperature through heat conduction, so that the temperature information of the charging IC can be obtained by setting a temperature sensing device in the charging IC.
In step S14, after the hardware of the mobile terminal is fixed, under the same charging condition, the temperature conditions of the internal charging IC and the heat dissipation element acting together and transferred to the mobile terminal casing are the same, and the casing temperature information detected by the temperature sensor is the temperature information obtained by the internal circuit of the mobile terminal and the heat dissipation element acting together on the mobile terminal casing, and the temperature sensor is set at the casing position corresponding to the first charging area in the mobile terminal, so that the area temperatures corresponding to the charging areas under different charging environments can be obtained. By way of example, the different charging point environments can be simulated through experiments, the mapping relation between the temperature information of the plurality of charging modules and the region temperatures corresponding to the plurality of charging regions in different environments can be obtained through detecting the shell temperatures at the corresponding positions, and the region temperatures of the first charging region corresponding to the temperature information of the charging modules in the first charging region can be obtained according to the mapping relation. For example, an NTC (negative temperature coefficient thermistor, negative Temperature Coefficient) may be provided inside the charging IC, the temperature information of the charging IC may be determined by measuring the resistance of the NTC and applying a correspondence relation between the resistance coefficient and the temperature, and the temperature information of the charging IC and the case temperature information may be integrated, so that the region temperature corresponding to the charging region may be determined.
Optionally, the step S14 may further include:
s143, based on the fitting parameters, acquiring the region temperature of the first charging region corresponding to the temperature information of the charging module in the first charging region.
It can be understood that the temperature of the shell when the mobile terminal is charged is affected by the configuration condition and the distribution condition of the internal circuit, the distribution condition of the heat dissipation area and other internal configurations, so that when the configuration of the mobile terminal is fixed, the temperature information of the internal charging IC and the temperature information of the external area satisfy a certain parameter relationship, and the corresponding relationship between the temperature information of the internal charging IC and the temperature of the external area can be obtained by detecting the temperature information of the charging IC and the temperature of the corresponding area under the same condition, and the fitting parameters between the temperature information of the charging IC and the temperature of the area can be determined according to the corresponding relationship and the data processing mode.
After the fitting parameters of the mobile terminal are determined, the region temperature corresponding to the external charging region at the moment can be obtained according to the temperature information of the internal charging IC of the mobile terminal.
Optionally, referring to fig. 3, fig. 3 is a flowchart of a method for determining a region temperature according to an exemplary embodiment of the disclosure, in a first implementation manner, before step S143, the control method may further include:
In step S141, a plurality of shell temperature information of the first charging area in a preset time period and temperature information corresponding to a plurality of charging modules are obtained, and the charging module temperature information is obtained by reading a temperature sensor in the charging module.
In step S142, fitting is performed on the plurality of charging module temperature information and the plurality of case temperature information to obtain fitting parameters.
It can be understood that the mobile terminal needs to adopt fine components for circuit control, so the sensitivity requirement on temperature is higher, the temperature change is usually in the range of 1 ℃, different degrees of influence can be possibly caused on the working states of part of components, and the internal temperature of the mobile terminal is increased to easily cause that the internal components cannot work normally, even the components are possibly damaged, therefore, the temperature needs to be subjected to fine measurement calculation in the present disclosure so as to represent the actual area temperature of the internal area of the mobile terminal, and further the corresponding charging IC temperature is controlled. In step S141, for example, in order to ensure that the obtained temperature of the area is more accurate, the temperature sensor is used to perform multiple collection and calculation on the shell temperature information in a preset time period to obtain multiple shell temperature information, and at the same time, NTC data inside the charging IC is read, and multiple charging module temperature parameters in the preset time period are obtained by referring to the correspondence between the resistance and the temperature.
In step S142, the plurality of shell temperature information and the plurality of charging module temperature information obtained according to the above steps are subjected to data fitting, wherein the data fitting is a manner of substituting data into a numerical expression through a mathematical method, a continuous function curve is obtained through data fitting to represent the known plurality of shell temperature information and the known plurality of charging module temperature information, and for example, a least square surface fitting function can be applied to obtain function values corresponding to the shell temperature information and the charging module temperature information, and fitting parameters can be obtained by reading the function values. For example, the fitting parameters may be obtained according to a plurality of charging module temperature information and a plurality of housing temperature information by a first formula:
wherein A is n Representing fitting parameters, wherein n is the number of temperature acquisition times in a preset time period, tshall n Representing a column matrix formed by n shell temperature information obtained by n temperature acquisitions and n corresponding time points, T ntcn The temperature information of the charging module and the coordinate information formed by the corresponding time point when the temperature sensor performs temperature acquisition for the nth time. For example, in order to make the obtained fitting parameters more accurate, the preset time is usually set to 40min, the shell temperature and the temperature of the NTC inside the charging IC are collected 80 times according to a data collection mode of 30s, 80 Tshall shell temperature information and 80 Tntc charging module temperature information are obtained, and the obtained temperature values are brought into the above formula, so that the corresponding fitting parameters are obtained.
Optionally, the area temperature may be obtained according to the fitting parameter and the temperature information of the plurality of charging modules through a second formula, where the second formula is:
wherein Tmit is n The temperature of the region calculated after n times of temperature acquisition is represented.
It will be appreciated that the fitting parameters determined by the above steps can be correlated with the temperature of the NTC inside the charging ICThe information is brought into the second formula, the temperature of the area corresponding to the charging area can be calculated and determined, and the Tshell temperature information and T are used for enabling the mobile terminal to quickly respond to the temperature ntc The charging module temperature information is the highest temperature information at the corresponding moment, and the region temperature determined according to the temperature information is used for representing the highest temperature of the corresponding charging region.
In step S15, after determining the region temperature corresponding to the charging region through the above steps, when the region temperature reaches the first temperature threshold, it is necessary to control the heating unit located within the charging region to reduce the temperature, and in general, the internal heating unit is the charging IC and the functional module, and the heating of the functional module is mainly due to frequent operations of the user outside, such as playing games, watching videos, browsing web pages, etc., and is not controllable as a user behavior of the mobile terminal, and in order to reduce the temperature of the internal region, in general, the heating value of the charging IC is adjusted by adjusting, for example, the first temperature threshold may be set to 38 ℃, and when the region temperature is greater than or equal to 38 ℃, the current of the charging IC of the corresponding region is adjusted, so as to achieve the effect of reducing the region temperature. It is understood that the above-mentioned region temperature detection and adjustment of the heating value of the charging IC are performed simultaneously for each charging region, and when the region temperature is greater than or equal to a preset temperature value, the heating value of the charging IC of the corresponding region is adjusted.
Optionally, the step S15 may further include:
in step S151, in the case where the region temperature is greater than or equal to the first temperature threshold, the charging current of the charging module is reduced so that the temperature information of the charging module is reduced.
In step S152, in case the temperature information of the charging module reaches the fourth temperature threshold, the mobile terminal is charged based on the corresponding charging current.
It may be understood that when the temperature of the area of the mobile terminal is greater than or equal to the first temperature threshold, this indicates that the temperature of the mobile terminal in the area reaches a dangerous temperature, and the dangerous temperature is easy to damage the working condition of the mobile terminal, so that a temperature reduction measure needs to be adopted.
According to the embodiment, temperature information of charging modules corresponding to a plurality of charging areas of the mobile terminal is obtained, the plurality of charging areas are divided according to distribution information of heat dissipation areas of the mobile terminal and distribution information of the charging modules of the mobile terminal, then the area temperature of a first charging area is determined based on the temperature information of the charging modules in the first charging area, the first charging area is any area in the plurality of charging areas, and the temperature information of the charging modules in the first charging area is adjusted under the condition that the area temperature is greater than or equal to a first temperature threshold value so that the temperature information is smaller than the first temperature threshold value. In this way, the mobile terminal is divided into a plurality of charging areas to monitor the temperature, the local heating condition of the mobile terminal is reflected according to the area temperature of the charging areas, and when the area temperature is greater than or equal to the first temperature threshold, the heating value of the charging module of the corresponding area is reduced to reduce the temperature of the area, so that the local position of the mobile terminal is subjected to temperature sensing and local charging temperature control, the concentration of heating points can be avoided, and the charging speed is ensured while the area temperature is reduced.
Optionally, referring to fig. 4, fig. 4 is a flowchart of a mobile terminal charging module scheduling method according to an exemplary embodiment of the present disclosure, where in the first implementation manner, the charging control method further includes:
in step S16, in the case where the plurality of region temperatures are all greater than or equal to the second temperature threshold, a first target charging region corresponding to the minimum region temperature is acquired.
In step S17, a first target charging module corresponding to the first target charging area is controlled to charge the mobile terminal.
In an example, when the temperature of the area corresponding to the charging area reaches the second temperature threshold, the charging current of the corresponding charging IC is reduced, in practical application, when the user frequently operates the corresponding functional module in the charging process, and the temperature of each charging area is raised to the second temperature threshold, in order to ensure the charging speed under the condition of keeping charging safety, the charging circuit of the charging area with the lowest temperature corresponding to the charging IC is selected to charge the battery of the mobile terminal, and meanwhile, the charging circuits corresponding to other charging ICs are closed, and in an example, the second temperature threshold is set to 40 ℃, when the temperature of the area of each charging area reaches 40 ℃, the temperature of the area of each charging area is compared, and the charging circuit corresponding to the charging IC with the lowest temperature of the area is selected to charge.
Optionally, referring to fig. 5, fig. 5 is a flowchart of another mobile terminal charging module scheduling method according to an exemplary embodiment of the present disclosure, where in the first implementation manner, the charging control method may further include:
in step S18, in the case where the temperatures of the plurality of regions are all greater than or equal to the third temperature threshold value, the second target charging region having the highest charging efficiency is acquired.
In step S19, a second target charging module corresponding to the second target charging area is controlled to charge the mobile terminal.
By way of example, setting the third temperature threshold to 42 ℃, when the charging temperatures corresponding to the respective areas are all greater than or equal to 42 ℃, obtaining the charging efficiency of the respective charging ICs corresponding to the charging areas, selecting the charging IC with the highest charging efficiency, closing the other charging ICs, charging the mobile terminal by using the charging circuit corresponding to the charging IC with the highest charging efficiency, and charging the mobile terminal at the relatively fastest charging speed, so that the mobile terminal rapidly reaches a full charge state, and thus the charging mode is exited to avoid the temperature influence caused by continuous charging. It may be understood that the charging efficiency of the charging IC is related to an adjusting loop inside the charging IC, specifically, the charging efficiency of the charging IC may be determined according to a ratio of the input power to the output power, for example, a correspondence relationship between the charging IC and the charging efficiency may be established, and by reading the correspondence relationship table, a target charging IC with the highest charging efficiency corresponding to the corresponding charging IC may be determined.
