Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an aspect of an embodiment of the present invention, there is provided a power supply control method.
As shown in fig. 1, the mobile terminal includes a dc-dc power supply module 101 and a WiFi module 102, where the dc-dc power supply module 101 supplies power to the WiFi module 102. The operating modes of the dc-dc power supply module 101 generally include: a PFM (Pulse Frequency Modulation) mode, a PWM (Pulse width Modulation) mode, and a pass-through BYPASS mode. The power supply capacity under the three modes is from weak to strong in sequence: PFM mode, PWM mode, BYPASS mode. To save power, the dc-dc power supply module 101 generally operates in the PFM mode.
As shown in fig. 2, the power supply control method includes:
In the step, whether the WiFi module in the mobile terminal is in a working state or not is determined by judging whether the mobile terminal is connected with the WiFi network or not.
The data transmission rate described herein refers to an upload rate or a download rate when data transmission is performed through a WiFi network.
If the mobile terminal is detected to be connected with the WiFi, the WiFi module is in a working state. When the WiFi module is in a working state and data are uploaded or downloaded through the WiFi network, the instantaneous power consumption is large, and when the direct current-direct current power supply module works in a PFM mode, the working frequency is low, the input voltage adjusting speed is low, the current output capacity is weak, and low-frequency power supply ripples appear on a power supply network due to the WiFi working scene.
As shown in fig. 3, the abscissa represents time, and the ordinate represents ripple voltage. When the data is transmitted through the WiFi network, the output voltage (i.e., ripple voltage) of the dc-dc power supply module drops from point a to point B, and when the data is transmitted, the output voltage of the dc-dc power supply module rises back from point B to point C. As can be seen from the figure, WiFi operates with a ripple power supply with a frequency of 200Hz, and has a large amplitude and a low frequency, and is easily heard by a user within the audible range of human ears.
Therefore, in order to reduce the capacitive sound, when the WiFi module is detected to be in the working state, the data transmission rate of the WiFi network needs to be detected in real time or at regular time, so as to determine a scheme to be adopted for dealing with the capacitive sound according to the detected data transmission rate.
And step 203, if the data transmission rate of the WiFi network is greater than a predetermined threshold, setting the working mode of the dc-dc power supply module to a PWM mode or a BYPASS mode, and supplying power to the WiFi module.
The preset threshold is a value (e.g., 1Mbps) with a higher data transmission rate. When the data transmission rate is greater than the predetermined threshold value, the generated capacitive sound is easy to be heard by the user, so that the capacitive sound needs to be suppressed, and the scheme adopted by the embodiment of the invention is as follows: and setting the working mode of the DC-DC power supply module to be a PWM mode or a BYPASS mode with stronger power supply capacity. The working frequency in the PWM mode is generally above 1MHz, the working frequency per se is not in the audible range of human ears (20Hz-20kHz), and the working frequency in the BYPASS mode is not available. The voltage output capacity under the two working modes is large, the output ripple voltage is small, the generated capacitance sound is small and is difficult to be heard by a user, and therefore the purposes of reducing the capacitance sound and ensuring the user use experience can be achieved.
As shown in fig. 4, the abscissa represents time, and the ordinate represents ripple voltage. The point a to the point B indicate that the output voltage of the dc-dc power supply module (i.e., the ripple power supply) drops instantaneously when data is transmitted through the WiFi network, and the point B to the point C indicate that the output voltage of the dc-dc power supply module rises again after data transmission is completed. As can be seen from the figure, the frequency of the output voltage of the dc-dc power supply module is also 200Hz, but the ripple amplitude is very small, which does not easily cause the capacitor to vibrate and is not easily heard by the user.
Further, when the data transmission rate of the WiFi network is less than the predetermined threshold, the generated capacitance sound is also small and is not easy to be heard by the user because the data transmission rate is small and the ripple voltage is small. However, if the ear of the user is tightly attached to the mobile terminal (for example, when the user uses the earpiece mode to make a call), the capacitive sound is still very obviously heard by the user, in order to avoid the influence of the capacitive sound on the use of the user, when the data transmission rate of the WiFi network is smaller than a predetermined threshold value, it is also required to detect whether the earpiece of the mobile terminal is in a working state, and if the earpiece of the mobile terminal is in the working state, the working mode of the dc-dc power supply module is set to the PWM mode or the BYPASS mode, so as to reduce the capacitive sound.
It can be understood that, when the data transmission rate of the WiFi network is less than the predetermined threshold and the earpiece of the mobile terminal is not in an operating state, the operating mode of the dc-dc power supply module may be set to the PFM mode to save power.
Specifically, when the operating mode of the dc-dc power supply module is set to the PWM mode or the BYPASS mode, the following two modes may be respectively adopted for which mode is specifically set:
one mode can be pre-designated, such as a designated PWM mode, so that when it is detected that the data transmission rate of the WiFi network is greater than a predetermined threshold value, or that the data transmission rate of the WiFi network is less than a predetermined threshold value, but the mobile terminal is in an earpiece operating state, the operating mode of the dc-dc power supply module is set to the PWM mode. If the BYPASS mode is designated, the implementation process is similar to that of the PWM mode, and thus the detailed description is omitted here.
And secondly, the specific setting mode can be determined according to the load voltage of the WiFi network (namely the voltage of the WiFi module).
Wherein, the lower the load voltage, the power supply mode with stronger power supply capability is needed to supply power, so the power supply mode needed when different load voltages are determined by the following method:
detecting the load voltage of the WiFi network, and if the load voltage is lower than a first preset voltage value and higher than a second preset voltage value, setting the working mode of the direct current-direct current power supply module to be a PWM mode; and if the load voltage is lower than a second preset voltage value, setting the working mode of the direct current-direct current power supply module to be a BYPASS mode.
The second preset voltage value is smaller than the first preset voltage.
Further, when it is detected that the receiver of the mobile terminal is no longer in the working state and the data transmission rate of the WiFi network is less than a predetermined threshold value, or the mobile terminal is not connected to the WiFi network, the working mode of the dc-dc power supply module is set to the PFM mode, so as to achieve the purpose of saving power.
In summary, in the power supply control method provided in the embodiment of the present invention, in order to avoid that the capacitive sound generated when the WiFi module is in the working state affects the user, the power supply mode of the dc-dc power supply module is changed by monitoring the data transmission rate of the WiFi network connected to the mobile terminal to supply power to the WiFi module, so as to reduce the capacitive sound, specifically: when the data transmission rate of the WiFi network is detected to be larger than a preset threshold value, or when the data transmission rate of the WiFi network is detected to be smaller than the preset threshold value and the earphone of the mobile terminal is in a working state, the working mode of the direct current-direct current power supply module is set to be a PWM mode or a BYPASS mode, so that the WiFi module works in a state with higher frequency, ripple voltage is reduced, and capacitance sound is reduced. In addition, the technical scheme provided by the embodiment of the invention improves the problem of capacitance sound in a software mode under the condition of not changing hardware, and has the advantages of small change on the mobile terminal and low development cost.
According to another aspect of the embodiments of the present invention, a mobile terminal is provided. The mobile terminal comprises a direct current-direct current power supply module and a WiFi module, wherein the direct current-direct current power supply module supplies power for the WiFi module.
As shown in fig. 5, the mobile terminal further includes:

Further, the setting module 503 is further configured to: when the data transmission rate of the WiFi network is smaller than a preset threshold value, detecting whether a receiver of the mobile terminal is in a working state; when the receiver of the mobile terminal is in a working state, the working mode of the direct current-direct current power supply module is set to be a PWM mode or a BYPASS mode, and power is supplied to the WiFi module.
Further, the setting module 503 is further configured to: and when detecting that the receiver of the mobile terminal is no longer in the working state and the data transmission rate of the WiFi network is less than a preset threshold value, setting the working mode of the direct current-direct current power supply module to be a Pulse Frequency Modulation (PFM) mode to supply power to the WiFi module.
Further, as shown in fig. 6, the setting module 503 includes:
a detecting unit 5031, configured to detect a load voltage of the WiFi network.
The first setting unit 5032 is configured to set the operating mode of the dc-dc power supply module to the PWM mode when the load voltage is lower than a first preset voltage value and higher than a second preset voltage value.
The second preset voltage value is smaller than the first preset voltage value.
The second setting unit 5033 is configured to set the operating mode of the dc-dc power supply module to a BYPASS mode when the load voltage is lower than a second preset voltage value.
In order to avoid that capacitive sound generated when the WiFi module is in a working state affects the use of a user, the mobile terminal provided in the embodiment of the present invention changes the power supply mode of the dc-dc power supply module by monitoring the data transmission rate of the WiFi network connected to the mobile terminal, and supplies power to the WiFi module, thereby reducing the capacitive sound, specifically: whether the mobile terminal is connected with the WiFi network is detected through the first detection module 501, and when the first detection module 501 detects that the mobile terminal is connected with the WiFi network, the second detection module 502 detects the data transmission rate of the WiFi network connected with the mobile terminal. When the second detection module 502 detects that the data transmission rate of the WiFi network is greater than the predetermined threshold, or detects that the data transmission rate of the WiFi network is less than the predetermined threshold and the earpiece of the mobile terminal is in the working state, the setting module 503 sets the working mode of the dc-dc power supply module to the PWM mode or the BYPASS mode to supply power to the WiFi module, so that the WiFi module works in a state with a higher frequency, the ripple voltage is reduced, and the capacitance sound is reduced. In addition, the technical scheme provided by the embodiment of the invention improves the problem of capacitance sound in a software mode under the condition of not changing hardware, and has the advantages of small change on the mobile terminal and low development cost.
