Therefore, the present application is not limited by the specific embodiments disclosed below. The description hereinafter sets forth a preferred embodiment for practicing the application, but is not intended to limit the scope of the application, as the description is given for the purpose of illustrating the general principles of the application. The scope of the application is defined by the appended claims.
The device charging method, device, terminal device and computer storage medium provided by the embodiment of the invention are specifically described below with reference to the accompanying drawings.
An embodiment of the present invention provides a device charging method, as shown in fig. 1, including:
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.
S141, acquiring load state parameters of the equipment.
S142, judging whether overload conditions are met according to the load state parameters.
If the step S142 meets the overload condition, determining that the device is in an overload state, and executing a step S151; if the overload condition is not satisfied in the step S142, it is determined that the device is in a normal load state, and step S152 is performed.
S151, determining that the used charging configuration parameters belong to a first type of charging configuration parameters. Step S160 is performed.
S152, determining that the used charging configuration parameters belong to a second type of charging configuration parameters. The step S160 is performed.
Wherein 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 corresponding set of charging configuration parameters in the first type of charging configuration parameters for the same device temperature is no greater than the charging current of a corresponding set of charging configuration parameters in the second type of charging configuration parameters.
S160, acquiring the current equipment temperature.
S170, determining a corresponding group of charging configuration parameters from subordinate charging configuration parameter categories according to the current equipment temperature.
The higher the equipment temperature is, the smaller the charging current is in a corresponding group of charging configuration parameters in the same type of charging configuration parameters.
And S180, controlling the equipment to charge according to the determined set of charging configuration parameters, and/or controlling a power adapter for charging the equipment to charge.
In an 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 electronic reader, a music player, a video player, and the like.
In a specific implementation process, as shown in fig. 2, for a device of an Android (Android) operating system, 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 embodiment of the invention can control the charging current to be lower in the running state of high load under the condition of the same temperature by dynamically controlling the charging current according to the current load and temperature of the equipment, thereby slowing down the temperature rising speed.
Optionally, as shown in fig. 1, the device charging method further includes:
if the result of step S122 is that the operating system is currently in the sleep state, step S153 is executed.
And S153, determining that the used charging configuration parameters belong to a third type of charging configuration parameters. The step S160 is performed.
Wherein the charging current of a group of charging configuration parameters corresponding to the same device 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 third type of charging configuration parameters.
In this way, by setting a larger charging current for the sleep state than for the wake state at the same temperature, the charging speed of the device can be increased.
Optionally, in the same type of charging configuration parameters, different groups of charging configuration parameters include a group of charging configuration parameters respectively corresponding to different trigger temperature ranges and a group of charging configuration parameters respectively corresponding to different recovery temperature ranges;
step S170, determining a corresponding set of charging configuration parameters from the subordinate charging configuration parameter categories 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 smaller than the equipment temperature acquired before the first preset time, determining a group of charging configuration parameters corresponding to a recovery temperature range to which the current equipment temperature belongs.
In the specific implementation process, comparing the current equipment temperature with the equipment temperature acquired before the first preset time period, and directly comparing the numerical value to determine through storing the equipment temperature acquired before the first preset time period; the trigger temperature range and the recovery temperature range corresponding to the charging configuration parameter set adopted when the current equipment temperature is acquired can also be determined.
For example, the determined set of charging configuration parameters is shown in table 1 below:
charging configuration parameter categories determined in Table 1
| Charging configuration parameter set | 1 | 2 | 3 | 4 |
| Charging current | 5.5A | 3.5A | 3A | 1.5A |
| Trigger temperature range | ＜38℃ | [38℃,42℃) | [42℃,46℃) | ≥46℃ |
| Recovery temperature range | ≤36℃ | (36℃,40℃] | (40℃,44℃] | ＞44℃ |
The current equipment temperature is 43 ℃, 3.5A current is adopted for charging when the current equipment temperature is collected, the first preset time period is 1 minute, and the equipment temperature collected before 1 minute is 41 ℃. Then, the temperature rise of the equipment in 1 minute can be directly determined according to the temperature of 43 ℃ to 41 ℃, and 3A is determined to be the current charging current according to the trigger temperature range of [42 ℃,46 ℃); or charging with 3.5A current when collecting the current temperature of the equipment is determined as the 2 nd group charging configuration parameters, but And 43 deg.c > 42 deg.c, the device was determined to warm up in this 1 minute, since 43 deg.c e 42 deg.c, 46 deg.c, 3A was determined to be the current charging current.
Therefore, corresponding charging configuration parameters are determined by adopting different temperature ranges for heating and cooling the equipment, so that the charging speed can be well balanced and accelerated, and the charging heating can be controlled.
Optionally, the device charging method further comprises:
In response to the operating system wake instruction, the operating system status flag parameter is updated to a system wake status value. (not shown in the drawings)
And in response to an operating system sleep instruction, updating the operating system status flag parameter to a system sleep status value. (not shown in the drawings)
As shown in fig. 3, the device charging method includes, in addition to the same steps as those shown in fig. 1:
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.
S121, reading the operating system state flag parameters. The step S122 is performed.
For an Android operating system, as shown in fig. 2, a sys node (/ sys/ctp/ctp_func/tpenable) may be created when the device is turned on, and then the power management service PowerManager may be invoked when the operating system sleeps or wakes up, modifying the value of this parameter. The step S110 and the step S121 are implemented by calling a temperature control service Thermal-engine.
For portable terminal devices (such as mobile phones and tablet computers), a brightness value of a screen is generally used in the prior art to determine whether an operating system goes into sleep (for example, when the brightness of the screen is 0, it is determined that the device has gone into a screen locking sleep state). For a terminal device with an ink screen, since the working principle of the ink screen is different from that of a Light Emitting screen such as a Liquid crystal display (Liquid CRYSTAL DISPLAY, LCD) screen and an Organic Light-Emitting Diode (OLED) screen, 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 an operation system sleep state or an awake state. Thus, by setting a system state flag parameter, the embodiment of the invention can judge the current state of the operating system through the parameter for the device of the ink screen.
Optionally, when determining that the operating system is in the awake state, acquiring the 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 an awake state and the state determined last time is a dormant 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 wake-up state and the last determined state is the wake-up state, acquiring the load state parameter of the equipment at a preset first frequency.
In this way, by switching to the charging configuration parameters of the first charging configuration parameter set first after the operating system is changed from the sleep state to the wake state, it is possible to avoid that the charging configuration parameters of the third charging configuration parameter set are still adopted when the data acquisition time corresponding to the first preset frequency is not yet reached, thereby better controlling 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: a central processing unit (Central Processing Unit, CPU) operating frequency, CPU power consumption, CPU occupancy, graphics processor (Graphics Processing Unit, GPU) operating frequency, GPU power consumption, GPU occupancy;
the specific time is a time with a cut-off point being a second preset duration of the current time.
In the implementation process, for some terminal devices (for example, mobile phones, tablet computers and the like carrying Android operating systems), the average power consumption and occupancy rates of the CPU and the GPU may be obtained through working frequency estimation, and then the average working frequency of the CPU and the GPU may be directly used as the load state parameter.
As an alternative embodiment, if the load status parameter includes a CPU operating frequency average value and a GPU operating frequency average value within a specific time, the overload condition includes:
the average working frequency of the CPU is larger than a first threshold value; or the average working frequency of the CPU is larger than a second threshold value, and the average working frequency of the GPU is larger 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 with an 8-core CPU as an example, the operating frequency of the CPU may be obtained by reading/sys/bus/CPU/devices/CPU 0-CPU 8, and the operating frequency of the GPU may be obtained by reading/sys/kernel/GPU.
Optionally, in the first type of charging configuration parameters, a group of charging configuration parameters corresponding to a trigger temperature range greater than a preset temperature threshold includes a charging limiting voltage;
Wherein the charging limit voltage is a nominal minimum charging voltage of the device or a nominal minimum charging voltage of the power adapter.
In the related art, device charging methods for devices include two types of schemes of charging using a fixed charging voltage and dynamically adjusting the charging voltage (e.g., USB power transfer protocol (USB Power Delivery, USB PD)). For the technical scheme of charging by using a fixed charging voltage, there are also schemes in the related art that a plurality of different rated charging voltages are provided, and one of the rated charging voltages is selected at the beginning of charging (a protocol handshake matching is generally adopted to select a larger rated charging voltage) for charging. In order to ensure the safety of equipment, the embodiment of the invention proposes that when the equipment is in high load and has higher temperature, the charging voltage is forcedly reduced to the rated minimum charging voltage, the charging conversion efficiency can be further improved, the temperature rise problem caused by voltage conversion is reduced, and the safety is ensured.
Specifically, table 2 below shows one specific charging configuration parameter, wherein the rated minimum charging voltage of the device is 5V:
