It should be noted that in the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.
The following describes a device charging method, an apparatus, a terminal device, and a computer storage medium according to embodiments of the present invention with reference to the accompanying drawings.
An embodiment of the present invention provides an apparatus charging method, as shown in fig. 1, including:
and S122, determining the current state of the operating system.
If the result of the step S122 is that the operating system is currently in the wake-up state, step S130 is executed.
S130, judging whether the data acquisition time corresponding to the first preset frequency is reached.
If the result of the step S130 is yes, step S141 is executed. If the result of the step S130 is no, the process returns to the step S122.
And S141, acquiring the load state parameters of the equipment.
And S142, judging whether the overload condition is met or not according to the load state parameters.
If the overload condition is satisfied in step S142, determining that the device is in an overload state, and executing step S151; if the overload condition is not satisfied in step S142, it is determined that the device is in a normal load state, and step S152 is performed.
And S151, determining that the used charging configuration parameters belong to the first type of charging configuration parameters. Step S160 is performed.
And S152, determining that the used charging configuration parameters belong to the second type of charging configuration parameters. The step S160 is executed.
The first type of charging configuration parameters and the second type of charging configuration parameters respectively comprise a plurality of groups of charging configuration parameters; the charging current of a group of charging configuration parameters corresponding to the same equipment temperature in the first type of charging configuration parameters is not greater than the charging current of a group of charging configuration parameters corresponding to the same equipment temperature in the second type of charging configuration parameters.
And S160, acquiring the current equipment temperature.
S170, determining a corresponding group of charging configuration parameters from the charging configuration parameter categories to which the equipment belongs according to the current equipment temperature.
In the same type of charging configuration parameters, the higher the equipment temperature is, the smaller the charging current in the corresponding group of charging configuration parameters is.
And S180, controlling the equipment to be charged according to the determined group of charging configuration parameters, and/or controlling a power adapter for charging the equipment to be charged.
In the implementation process, the device includes, but is not limited to, a terminal device such as a smart phone, a tablet computer, a portable game machine, an e-reader, a music player, and a video player.
In a specific implementation process, as shown in fig. 2, for an Android operating system device, the step S160 may obtain the device temperature by reading/sys/class/thermal/thermal _ zone, and the step S180 may be implemented by writing the charging configuration parameter into/sys/class/power _ supply/battery.
Because the equipment can emit a large amount of heat under the condition of high load, the charging current is dynamically controlled according to the current load and the temperature of the equipment, so that the charging current can be controlled to be lower under the condition of the same temperature under the operation state of the high load, and the temperature rising speed is slowed down.
Optionally, as shown in fig. 1, the device charging method further includes:
if the result of the step S122 is that the operating system is currently in the hibernation state, step S153 is executed.
And S153, determining that the used charging configuration parameters belong to the third type of charging configuration parameters. The step S160 is executed.
And the charging current of a group of charging configuration parameters corresponding to the same equipment temperature in the second type of charging configuration parameters is not greater than the charging current of a group of charging configuration parameters corresponding to the same equipment temperature in the third type of charging configuration parameters.
In this way, by setting a larger charging current for the sleep state than for the awake state at the same temperature, the charging speed of the device can be increased.
Optionally, in the same type of charging configuration parameters, the different sets of charging configuration parameters include a set of charging configuration parameters corresponding to different trigger temperature ranges, and a set of charging configuration parameters corresponding to different recovery temperature ranges;
step S170, determining a corresponding set of charging configuration parameters from the charging configuration parameter categories to which the device is subordinate according to the current device temperature, including:
if the current equipment temperature is greater than the equipment temperature acquired before the first preset time, determining a group of charging configuration parameters corresponding to a trigger temperature range to which the current equipment temperature belongs;
and if the current equipment temperature is less than the equipment temperature acquired before the first preset time, determining a group of charging configuration parameters corresponding to the recovery temperature range to which the current equipment temperature belongs.
In a specific implementation process, comparing the current equipment temperature with the equipment temperature obtained before the first preset time, and directly comparing numerical values to determine the equipment temperature by storing the equipment temperature obtained before the first preset time; or the trigger temperature range and the recovery temperature range corresponding to the charging configuration parameter group adopted when the current device temperature is obtained may be determined.
For example, the determined set of charging configuration parameters is shown in table 1 below:
TABLE 1 charging configuration parameter classes
| Charging configuration parameter set | 1 | 2 | 3 | 4 |
| Charging current | 5.5A | 3.5A | 3A | 1.5A |
| Triggering temperature range | ＜38℃ | [38℃,42℃) | [42℃,46℃) | ≥46℃ |
| Recovery of temperature range | ≤36℃ | (36℃,40℃] | (40℃,44℃] | ＞44℃ |
The current temperature of the equipment is 43 ℃, the current of 3.5A is adopted for charging when the current temperature of the equipment is collected, the first preset time is 1 minute, and the temperature of the equipment collected before 1 minute is 41 ℃. Then, the temperature rise of the equipment within 1 minute can be determined directly according to the temperature of 43 ℃ being more than 41 ℃, and 3A is determined as the current charging current according to the triggering temperature range [42 ℃,46 ℃; or, the current of 3.5A is adopted for charging according to the current collected temperature of the equipment to determine the 2 nd group of charging configuration parameters, but
And 43 ℃ is > 42 ℃, the device is determined to be warm in this 1 minute, and 3A is determined to be the present charging current due to 43 ∈ [42 ℃,46 ℃).
Therefore, the corresponding charging configuration parameters are determined by adopting different temperature ranges for heating and cooling the equipment, so that the charging speed can be accelerated and the charging heating can be controlled in a better balanced manner.
Optionally, the device charging method further includes:
and responding to the operating system awakening instruction, and updating the operating system state mark parameter to a system awakening state value. (not shown in the figure)
And responding to an operating system sleep instruction, and updating the operating system state mark parameter to a system sleep state value. (not shown in the figure)
As shown in fig. 3, the device charging method further includes, in addition to the same steps as those shown in fig. 1:
and S110, judging whether the data acquisition time corresponding to the second preset frequency is reached.
If the result of the step S110 is yes, the step S121 is executed. If the result of the step S110 is no, the step S130 is executed.
And S121, reading the state flag parameter of the operating system. The step S122 is executed.
For the Android operating system, as shown in fig. 2, a sys node (/ sys/ctp/ctp _ func/tpendable) may be created when the device is powered on, and then the power management service PowerManager may be called when the operating system is hibernated or awakened to modify the value of the parameter. The step S110 and the step S121 are implemented by calling a Thermal-engine service.
For portable terminal devices (e.g., mobile phones, tablet computers, etc.), it is common in the prior art to use the brightness value of the screen to determine whether the operating system goes to sleep (e.g., when the screen brightness is 0, it is determined that the device has already gone into a lock screen sleep state). For a terminal device with an ink screen as a Display screen, since the operating principle of the ink screen is different from that of Light Emitting screens such as Liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) screens, if a backlight is not additionally provided or the device is turned off although the backlight is provided, the ink screen does not emit Light in a sleep or wake-up state of an operating system. Thus, the embodiment of the invention can judge the current state of the operating system through the parameter of the ink screen device by setting the system state flag parameter.
Optionally, when it is determined that the operating system is in the wake-up state, acquiring a load state parameter of the device at a preset first frequency, including (not shown in the figure):
when the state of the operating system is determined to be the awakening state and the last determined state is the sleeping state, determining a corresponding group of charging configuration parameters from the second type of charging configuration parameters according to the current equipment temperature;
and when the state of the operating system is determined to be the awakening state and the last determined state is the awakening state, acquiring the load state parameters of the equipment at a preset first frequency.
In this way, by switching to the charging configuration parameter of the first charging configuration parameter group after the operating system changes from the sleep state to the wake-up state, it can be avoided that the charging configuration parameter of the third charging configuration parameter group is still adopted when the data acquisition time corresponding to the first preset frequency is not reached, so as to better control the temperature of the device during charging.
Optionally, the load state parameter includes an average value of at least one of the following parameters over a specific time: central Processing Unit (CPU) operating frequency, CPU power consumption, CPU occupancy, Graphics Processing Unit (GPU) operating frequency, GPU power consumption, GPU occupancy;
the specific time is the time with the cut-off point being the second preset duration of the current time.
In a specific implementation process, for some terminal devices (for example, a mobile phone, a tablet computer, etc. equipped with an Android operating system), the average values of the power consumption and the occupancy rate of the CPU and the GPU may be obtained by estimating the operating frequency, and then the average values of the operating frequency of the CPU and the GPU may be directly used as the load state parameters.
As an optional implementation manner, if the load status parameter includes the CPU operating frequency average value and the GPU operating frequency average value in a specific time, the overload condition includes:
the average working frequency of the CPU is greater than a first threshold; or the average working frequency of the CPU is greater than a second threshold value, and the average working frequency of the GPU is greater than a third threshold value.
For example, the first threshold is 85% of the maximum operating frequency of the CPU, the second threshold is 70% of the maximum operating frequency of the CPU, and the third threshold is 70% of the maximum operating frequency of the GPU. And when the CPU working frequency average value of the equipment is greater than 85% of the maximum working frequency, or the CPU working frequency average value is greater than 70% of the maximum working frequency and the GPU working frequency average value is greater than 70% of the maximum working frequency, the equipment adopts the charging configuration parameters in the first type of charging configuration parameters to charge, otherwise, the equipment adopts the charging configuration parameters in the second type of charging configuration parameters to charge.
In a specific implementation process, as shown in fig. 2, for a device of the Android operating system, taking a device of a CPU with 8 cores as an example, the working frequency of the CPU may be obtained by reading/sys/bus/CPU/devices/CPU 0-CPU 8, and the working frequency of the GPU may be obtained by reading/sys/kernel/GPU.
Optionally, a group of charging configuration parameters corresponding to a trigger temperature range greater than a preset temperature threshold in the first type of charging configuration parameters includes a charging limit voltage;
wherein the charging limit voltage is a rated minimum charging voltage of the device or a rated minimum charging voltage of the power adapter.
In the related art, a device charging method for a device includes two types of schemes of charging using a fixed charging voltage and dynamically adjusting the charging voltage (for example, a USB Power Delivery (USB PD)). As for the technical scheme of charging with a fixed charging voltage, there is also a scheme of providing a plurality of different rated charging voltages and selecting one of the rated charging voltages (generally, selecting a larger rated charging voltage by using protocol handshake matching) for charging when charging is started in the related art. In order to ensure the safety of the equipment, the embodiment of the invention provides that when the equipment is under high load and has higher temperature, the charging voltage is forcibly reduced to the rated minimum charging voltage, the charging conversion efficiency can be further improved, the temperature rise problem caused by voltage conversion can be reduced, and the safety is ensured.
Specifically, one specific charging configuration parameter is shown in table 2 below, where the rated minimum charging voltage of the device is 5V:
TABLE 2 charging configuration parameters
