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 drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A charge control method, a power management integrated chip, a terminal device, and a storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
In the process of charging the terminal device, if the service provided by the terminal device, such as making a call, chatting with a video, etc., is used, the charging behavior may cause interference to the executed service, and affect the use experience of the user.
In order to reduce the interference caused by the charging of the terminal device to the executed service, the conventional scheme mostly adopts a hardware shielding measure to reduce the interference. The following three common hardware shielding measures are used:
(1) electromagnetic Interference (EMI) ink is sprayed on a printed circuit flexible board which charges the whole Universal Serial Bus (USB), so that the Interference frequency cannot be leaked outwards;
(2) an exposed copper wire of a USB-charged printed circuit soft board is connected with a middle frame front shell of a terminal, so that the aim of grounding is fulfilled, and energy of interference frequency can be quickly led into the ground;
(3) the peripheral devices of the charging terminal of the Power Management Integrated Circuits (PMIC), such as the common diode nonlinear devices, increase the large capacitance to ground, so that the interference frequency generated by the diode can be quickly led to the ground to avoid leakage.
The traditional hardware shielding measures (spraying EMI printing ink and wrapping and grounding by copper foil) can prevent the interference frequency on the printed circuit soft board from leaking or intensively reflowing, guide the interference into the ground in time and avoid the leakage of the interference frequency. However, the adoption of the hardware shielding mode increases extra hardware cost, cannot ensure complete shielding and interference reduction, has requirements on the hardware structure, and cannot perform hardware shielding on the structure which cannot be sprayed with EMI ink or wrap a copper foil grounding area. In addition, when the interference is reduced by adopting a mode of quickly guiding the interference into the ground by tuning the capacitance value of the peripheral device of the PMIC charging end, the capacitance value of the capacitor is selected through experience, and the effect cannot be ensured.
In view of the above problems, an embodiment of the present invention provides a charging control method to reduce unnecessary current consumption and reduce interference of charging on a service being executed by a terminal.
Fig. 1 is a flowchart illustrating a charging control method according to an embodiment of the present invention, where the method may be executed by a terminal device, where the terminal device may be, for example, a mobile phone, a tablet computer, or another terminal that needs to be charged by using an adapter.
As shown in fig. 1, the charge control method may include the steps of:
In this embodiment, the charging interface of the terminal may be monitored, and when it is monitored that the charging interface of the terminal is called, it may be determined that the terminal is currently in a charging state. At this time, for the terminal in the charging state, whether the service being executed exists in the terminal may be continuously detected, so as to determine whether other services, such as call, internet access, and the like, are being executed in the terminal charging process.
As an example, the currently executed task may be determined according to a program in the terminal, which is in the foreground, where the program in the foreground may be a system application, such as a call application, a browser of the system automation, a weather application, and the like, or an application installed by a user through self-downloading, such as a music application, a game application, an instant messaging software, and the like. For example, when the program running in the foreground is dialing, it may be determined that the service being executed is dialing; when the program running in the foreground is a camera, it can be determined that the service being executed is photographing.
In a terminal, each service needs to be supported by a corresponding hardware device, for example, the implementation of a telephone service needs to be supported by a microphone, an analog-to-digital converter and a Power Amplifier (PA), and a photographing service needs to be supported by an image sensor; the wireless internet function requires the support of a wireless WiFi module, and the like.
Therefore, in this embodiment, a target device supporting a currently executed service in the terminal may be determined according to the determined service being executed in the terminal.
And 103, adjusting the power supply power of the charging system in the terminal for supplying power to the target device and the non-target device.
The non-target device is other devices except the target device in the devices powered by the charging system. For example, the charging system supplies power to a microphone, an analog-to-digital converter, a PA, a wireless WiFi module, an image sensor, and a speaker, and the service currently being performed by the terminal is a telephone service, and since the telephone service is implemented by the support of the microphone, the analog-to-digital converter, and the PA, that is, the target device includes the microphone, the analog-to-digital converter, and the PA, the non-target device includes the wireless WiFi module, the image sensor, and the speaker.
In this embodiment, after the target device supporting the service being executed is determined, the power supply power of the charging system in the terminal for supplying power to the target device and the non-target device may be adjusted according to the determined target device.
Specifically, the basic normal operation of each device (i.e., each non-target device) except the target device in the terminal may be maintained only, so that the power taking of the charging system by the non-target device is reduced, unnecessary current consumption is reduced, and the energy generating the interference frequency is reduced without affecting the normal function of the non-target device. Alternatively, the unnecessary devices may be temporarily turned off to reduce the power draw of other devices to the charging system.
In the charging control method of this embodiment, when the terminal is in a charging state, the service currently being executed in the terminal is acquired, and the target device supporting the service currently being executed in the terminal is determined, so that the power supply power of the charging system in the terminal for supplying power to the target device and the non-target device is adjusted. Therefore, electricity taking of other devices except the target device to the charging system can be reduced, unnecessary current consumption is reduced, interference of charging on the service being executed by the terminal is reduced, and user experience is improved.
In order to more clearly describe a specific implementation process of adjusting the power supply power of the charging system in the terminal to supply power to the target device and the non-target device in the foregoing embodiment, three possible implementation manners are provided in the embodiments of the present invention.
As one of the possible implementations, the supply current of the charging system to power the non-target device may be reduced. In this embodiment, after the target device is determined, the supply current of the target device may be kept unchanged, and the supply currents of other devices except the target device may be reduced, so as to achieve the purpose of reducing interference.
Further, in a possible implementation manner of the embodiment of the present invention, before reducing the supply current of the charging system for supplying power to the non-target device, the minimum operating current of each non-target device may be determined first, so as to ensure normal operation of each non-target device. Fig. 2 is a flowchart illustrating a method for obtaining a minimum operating current of a non-target device according to an embodiment of the present invention.
As shown in fig. 2, obtaining the minimum operating current of each non-target device may include the following steps:
In this embodiment, in a state where the terminal normally operates, power consumption of each device in the terminal in a unit time (for example, 1 second) when the device is in the lowest operating mode may be obtained as power consumption of each device in the unit time. For example, for a display screen, the backlight power consumption per unit time corresponding to the lowest screen brightness of the display screen may be obtained as the lowest power consumption per unit time of the display screen. For devices without the lowest operating mode, the lowest power consumption can be determined by means of statistical analysis.
For example one, for each device, the power consumptions of a plurality of units of time may be obtained, and one minimum power consumption may be selected as the minimum power consumption of the device.
For example two, for each device, the power consumptions of a plurality of units of time may be obtained, and the average of the plurality of power consumptions may be calculated as the lowest power consumption of the device.
In this embodiment, the lowest power consumption of each device in the terminal in the unit time may be stored in the local memory, and after the target device is determined, the lowest power consumption of the other devices except the target device may be directly obtained from the local memory.
In this embodiment, for each device other than the target device, the minimum operating current corresponding to the device may be determined according to the operating voltage of the device and the minimum power consumption per unit time. Since power is the product of voltage and current, and power consumption is defined as the difference between input power and output power, in this embodiment, the ratio of the lowest power consumption and the operating voltage in the unit time corresponding to the non-target device may be used as the minimum operating current of the non-target device.
And then, according to the minimum working current corresponding to the non-target device, reducing the power supply current of the charging system for supplying power to each non-target device, so that the charging system supplies power to each corresponding non-target device by using the minimum working current corresponding to each non-target device, and the interference on the service being executed is reduced.
In summary, by determining the minimum power consumption of each non-target device in the normal operating state of the terminal in unit time and then determining the minimum operating current corresponding to each non-target device according to the operating voltage and the minimum power consumption of each non-target device in unit time, a basis can be provided for the charging system to reduce the supply current of each non-target device, the normal operation of each non-target device is ensured, and the problem that each non-target device cannot normally operate due to too small supply current is avoided.
As one possible implementation manner, as shown in fig. 3, on the basis of the embodiment shown in fig. 1, step 103 may include the following steps:
Each device has its own corresponding function, for example, the speaker is used for amplifying an audio signal, the microphone is used for acquiring an audio signal, the WiFi module is used for implementing a wireless internet access function, and the like.
For example, generally speaking, the image sensor can be used when taking a picture, the microphone and the speaker can be used when making a call or sending voice information and voice search, the WiFi module can be used when the user accesses the internet, and can also be used when the user performs video chat and voice search, therefore, for the image sensor, the microphone, the speaker and the WiFi module, the corresponding power adjustment level can be set from high to low as: image sensor-microphone, speaker-WiFi module.
And 303, adjusting the power supply current of the charging system for supplying power to the non-target device according to the power adjustment level respectively corresponding to each non-target device.
In this embodiment, it may be set that the higher the power adjustment level is, the larger the adjustment amplitude of the corresponding supply current is, the higher the power adjustment level is, the non-target devices of the image sensor-microphone and the speaker-WiFi module are sequentially set from high to low, the adjustment amplitude of the supply current of the image sensor is the largest, the microphone and the speaker are the next, the adjustment amplitude of the supply current of the WiFi module is the smallest, and then, the charging system supplies power to each non-target device according to the adjusted supply current.
In the charging control method of this embodiment, the functions of the non-target devices are determined, the corresponding power adjustment levels are determined according to the functions corresponding to the non-target devices, and then the power supply current supplied by the charging system to the non-target devices is adjusted according to the power adjustment levels corresponding to the non-target devices, so that the power supply current can be adjusted for the devices in a targeted manner, and the flexibility of adjusting the power supply current is improved.
As one possible implementation manner, when the supply current of the charging system in the terminal is adjusted to supply power to the target device and the non-target device, the duty ratio and/or the operating frequency of the voltage converter in the charging system, which supplies power to the target device and the non-target device, may be adjusted.
Since rated operating voltages of various devices in the terminal are different, a corresponding voltage converter is integrated in the PMIC for each device, and in this embodiment, the supply current of each device can be adjusted by adjusting the voltage duty cycle and/or the operating frequency. Specifically, for non-target devices, the duty cycle and/or operating frequency of the corresponding voltage converter may be adjusted down to reduce the supply current of the charging system to power the non-target devices. It should be noted that when the duty ratio and/or the operating frequency of the voltage converter of each non-target device is adjusted, it should be ensured that the normal operation of each non-target device is not affected.
By adjusting the duty ratio and/or operating frequency of the voltage converter supplying power to the target device and the non-target device, the supply current of each device can be adjusted to reduce the interference caused by the larger supply current of other devices to the service being executed.
In the embodiment of the present invention, the charging system may be a power management chip PMIC. A PMIC is usually integrated inside the terminal to manage the power states inside the terminal. For example, various sensors, power amplifiers, speakers, etc. used in the terminal are powered, and a battery of the terminal is charged. Because rated operating voltages of various devices are different, a plurality of switch circuits (DC/DC voltage converters) are integrated in the PMIC, and the switch circuits generate different frequency components in the opening and closing processes, usually, the frequency components of the frequency components are low, but the frequency components are frequency-doubled when passing through some non-linear devices or circuits on the periphery of the PMIC along with the output voltage of the PMIC, and the frequency components after frequency doubling can be accessed into the frequency band of a call or an internet, so as to cause interference to the call or the internet service.
When the terminal is charged by using the adapter, the PMIC is also responsible for supplying power to a PA (power amplifier) for making a call while charging a battery, and when the battery is charged, the frequency generated by current passing through a non-linear device and a circuit on the periphery of the PMIC can generate interference on conversation. In the process of terminal charging, except that the PA works, other devices of the system consume power, when other devices get power from the PMIC, the current passing through the peripheral nonlinear device and the circuit is also larger, but because a user needs to ensure the call quality when passing through the PMIC at the moment, in the embodiment, the current of other devices can be switched into a low-current mode or unnecessary devices are directly and temporarily closed under the condition of not influencing the normal work of other devices, so that the current obtained from the PMIC by other devices except the PA can be reduced, unnecessary current consumption is reduced, the current passing through the nonlinear device or the circuit is also reduced, the energy of interference frequency is reduced, and the purpose of reducing interference is achieved.
Fig. 4 is a schematic diagram of the current flow during the terminal charging process. As shown in fig. 4, the terminal adapter charges the terminal through the terminal charging interface, wherein the input voltage forms the input voltage of the PMIC after passing through the reverse protection circuit and the overvoltage protection, and a part of the voltage flowing into the PMIC flows out from the output terminal VBAT _ RST, and is sent to the battery through the switch circuit, and supplies power to the power amplifier PA. In addition to charging the battery and powering the PA, the voltage flowing into the PMIC may also have a portion flowing out of the output VPH _ PWR to power other components of the system, such as the baseband chip, display driver, WiFi module, etc. shown in fig. 4. The output VPH _ PWR is usually connected with more nonlinear devices and circuits, and the interference is larger. By adopting the charging control method of the embodiment, when the call service is executed in the terminal charging process, unnecessary current supply of the VPH _ PWR terminal can be reduced, so that the device connected with the VPH _ PWR terminal only maintains basic normal operation, the interference of current obtained by other devices from the PMIC to the call service is reduced, and after the call is finished, the power supply in the normal mode is recovered.
In order to implement the above embodiments, the present invention further provides a charging control apparatus.

After the minimum current determining module 550 determines the minimum working current corresponding to each non-target device, the adjusting module 530 may reduce the power supply current for the charging system to supply power to each non-target device according to the minimum working current of each non-target device, so that the charging system supplies power to each corresponding non-target device with the minimum working current corresponding to each non-target device.
The minimum power consumption of each non-target device in the unit time corresponding to each non-target device in the normal working state of the terminal is determined, and then the minimum working current corresponding to each non-target device is determined according to the working voltage corresponding to each non-target device and the minimum power consumption in the unit time, so that a basis can be provided for a charging system to reduce the power supply current of each non-target device, the normal work of each non-target device is ensured, and the problem that each non-target device cannot work normally due to the fact that the power supply current is too small is avoided.
