The wearable device shown in some embodiments of the present application may include a power chip for supplying power to the device, and a battery for providing an input voltage to the power chip. The working mode of the power supply chip can comprise a first mode and a second mode.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for supplying power to a wearable device according to some embodiments of the present disclosure.
As shown in fig. 1, the method may include S102-S106.
And S102, acquiring the current input voltage provided by the battery.
The battery may be any type of battery. Such as alkaline batteries, lithium batteries, lead acid batteries, etc., and the present application is not limited to the type of battery. The battery is connected with the input voltage end of the power supply chip and can provide input voltage for the power supply chip. During the use process of the battery, the electric quantity changes from high to low, namely the input voltage provided by the battery for the power supply chip is gradually reduced. For example, in a wearable device, the input voltage provided by the battery gradually decreases in the voltage range of 3.4-4.4 volts during power usage. This application aim at promotes in the battery use, power supply chip's power supply efficiency.
The input voltage can be from a battery, can be a voltage output by the battery, namely a voltage at a voltage output end of the battery, or can be a voltage input to a power supply chip after the voltage output by the battery passes through one or more electronic components, and the voltage is used for supplying power to the power supply chip.
In some embodiments, the device may include a charge detection unit. The unit can monitor the electric quantity of the battery in real time. The current electric quantity of the battery can be determined by obtaining the detection result of the electric quantity detection unit on the electric quantity of the battery. According to the battery power supply principle, the electric quantity of the battery and the voltage of the battery have a conversion relation. According to the conversion relationship, the electric quantity can be converted into the voltage of the battery. The electric quantity detection unit can be an electric quantity detection hardware circuit, an integrated chip or an electric quantity meter and the like. In some embodiments, the power detection unit may be a voltage type power detection unit, by which the current input voltage provided by the battery may be directly acquired. It should be noted that there are various ways to obtain the output voltage of the battery, and this is not exhaustive.
S104, determining a target working mode of the power supply chip based on the current input voltage; wherein the target operating mode is one of the first mode and the second mode.
In some embodiments, the selection of the target operating mode enables the power supply efficiency of the power supply chip under the current input voltage to meet a preset power supply condition.
The preset power supply condition may be various, for example, the preset power supply condition may include a maximum value of power supply efficiencies of the power chip in the first mode and the second mode, respectively, and for example, the preset power supply condition may include that the power supply efficiency of the power chip is higher than a specific threshold, and the like. In some embodiments, the preset power supply condition may further consider other factors, such as voltage, switching frequency, power consumption, and the like, besides the power supply efficiency, which is not limited in this application.
In some embodiments, the first mode and the second mode may be a symmetric mode and an asymmetric mode, respectively, or the first mode and the second mode may also be other modes, which is not limited to this embodiment of the present application. The power supply chip can respectively carry out voltage conversion on input voltage in two working modes and output different voltages. In some embodiments, the voltage dependence of the power supply efficiency of the power supply chip in the two operation modes can be determined, and based on the voltage dependence, a suitable operation mode is selected under the current voltage condition.
For example, the power chip B may have two operation modes. When the chip B works in the first mode, a voltage of 4.6 volts can be output externally. The closer the input voltage of chip B is to 4.6 volts, the higher the power supply efficiency of chip B. Referring to fig. 2, fig. 2 is a schematic diagram of a power supply efficiency curve according to some embodiments of the present application, and as shown by a solid line in fig. 2, the power supply efficiency curve of the chip B in the first mode may show an upward trend when the voltage is less than 4.6 volts.
When the chip B works in the second mode, 3.3V voltage can be output externally. When the input voltage of the chip B is closer to 3.3v, the power supply efficiency of the chip B is higher, as shown by the solid line 2 in fig. 2, and the power supply efficiency curve of the chip B in the second mode shows a downward trend.
It can be seen that the power supply efficiency curves of the chip B in the first mode and the second mode respectively show an upward trend and a downward trend in the interval from the low voltage of 3.3v to the high voltage of 4.6 v, that is, the two power supply efficiency curves are two intersecting curves.
In this way, based on the dependency curve shown in fig. 2 and the current input voltage provided by the battery, the target operation mode with higher power supply efficiency can be determined in the first mode and the second mode.
In some embodiments, in S104, the power supply efficiency of the power supply chip may be determined based on the current input voltage; and determining a target working mode of the power supply chip based on the power supply efficiency.
In some embodiments, in S104, the target operation mode of the power supply chip may be determined by comparing a magnitude relationship between the current input voltage and a preset voltage threshold.
For example, in the dependency curve shown in fig. 2, the first mode and the second mode have higher power supply efficiency under low voltage and high voltage conditions, respectively, so that the set voltage threshold can be preset based on the dependency curve shown in fig. 2, and the current voltage is compared with the preset voltage threshold, without calculating the power supply efficiency in real time, so as to improve the determination efficiency of the target operation mode. In the following embodiments, the above two manners of determining the target operating mode are specifically described. It should be noted that S104 may also include other embodiments based on a principle similar to the two aforementioned ways, and is not exhaustive here.
S106, setting the working model of the power supply chip to be the target working mode so that the power supply chip supplies power to the equipment.
In some embodiments, an operation mode setting instruction may be sent to the power supply chip through a mode setting interface preset for the power supply chip to set an operation mode of the power supply chip.
The power supply chip can be connected with the mainboard of the equipment through the mode setting interface. The device may send a setting instruction to the chip through the interface to set the operating mode of the power supply chip to the target operating mode. The setting instruction is a pre-agreed instruction for setting the working mode of the power supply chip.
In the technical scheme that this application embodiment recorded, because wearing equipment can be based on current input voltage, confirm power chip's power supply efficiency satisfies the target mode of predetermineeing the power supply condition, and will power chip's work model sets up to target mode, consequently wearing equipment can set up power chip power supply mode according to the voltage that the battery provided in the battery use, makes power chip satisfy the target mode of predetermineeing the power supply condition with power supply efficiency all the time and work, compares with only adopting single power supply mode, can promote power chip average power supply efficiency in the battery use, and then promotes equipment duration.
In some embodiments, in S104, the target operation mode of the power supply chip may be determined by comparing a magnitude relationship between the current input voltage and a preset voltage threshold.
The preset voltage threshold may be determined based on a voltage dependency relationship of power supply efficiency of the power supply chip in the first mode and the second mode.
In some embodiments, when the preset voltage threshold is determined, the power supply efficiency corresponding to the power supply chip in the first mode and the second mode may be analyzed to obtain power supply efficiency curves corresponding to the first mode and the second mode, respectively. An abscissa corresponding to the power supply efficiency curve represents an input voltage, and an ordinate corresponding to the power supply efficiency curve represents power supply efficiency. The supply efficiency curve may indicate a voltage dependence of the supply efficiency of the voltage chip.
Then, a voltage value corresponding to an intersection point of the power supply efficiency curves corresponding to the first mode and the second mode may be used as the preset voltage threshold.
Therefore, under the condition that the input voltage is higher than the preset voltage threshold, the power supply efficiency of the power supply chip in the first mode is higher than that in the second mode; and under the condition that the input voltage is lower than the preset voltage threshold, the power supply efficiency of the power supply chip in the second mode is higher than that in the first mode.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining a target operating mode according to some embodiments of the present application. Fig. 3 is a description of the foregoing step S104. As shown in fig. 3, the method may include S301-S303.
And S301, comparing the current input voltage obtained in the S102 with a preset voltage threshold value.
The relatively large and small methods can be referred to in the related art and will not be described in detail here.
S302, responding to the output voltage reaching the preset voltage threshold, and determining a first mode as the target working mode.
And S303, in response to the output voltage not reaching the preset voltage threshold, determining a second mode as the target working mode.
Under the condition that the input voltage is higher than a preset voltage threshold, the power supply efficiency of the power supply chip in the first mode is higher than that in the second mode; under the condition that the input voltage is lower than the preset voltage threshold, the power supply efficiency of the power supply chip in the second mode is higher than the power supply efficiency of the power supply chip in the first mode, so that the target working mode with the highest power supply efficiency of the power supply chip under the current input voltage can be determined through S301-S303, the power supply mode of the power supply chip can be set according to the voltage provided by the battery in the battery using process of the wearable device, the power supply chip can always work in the target working mode with the power supply efficiency meeting the preset power supply condition, and the average power supply efficiency of the power supply chip in the battery using process is improved.
In some embodiments, in S104, S1042 may be performed, determining a power supply efficiency of the power supply chip based on the current input voltage; s1044, determining a target working mode of the power supply chip based on the power supply efficiency.
In some embodiments, the power supply efficiency corresponding to the power chip in the first mode and the second mode may be analyzed to obtain power supply efficiency curves corresponding to the first mode and the second mode, respectively. The supply efficiency curve may indicate a voltage dependence of the supply efficiency of the voltage chip. In S1042, a first operating efficiency and a second operating efficiency of the voltage chip in the first mode and the second mode respectively may be determined according to the current input voltage based on the dependency relationship indicated by the power supply efficiency curves corresponding to the first mode and the second mode respectively.
In S1044, in response to the first operating efficiency being greater than or equal to the second operating efficiency, determining the first operating mode as the target operating mode; determining the second operating mode as the target operating mode in response to the first operating efficiency being less than the second operating efficiency.
Therefore, the target working mode of the power chip with the highest power supply efficiency under the current input voltage can be determined through S1042-S1044, so that the power supply mode of the power chip can be set according to the voltage provided by the battery in the use process of the battery of the wearable device, the power chip always works in the target working mode with the power supply efficiency meeting the preset power supply condition, and the average power supply efficiency of the power chip in the use process of the battery is improved.
In some embodiments, the wearable device may further include a display module. The power supply chip can be used for supplying power for the display module.
The display module may include any type of display. For example, the display module can be a liquid crystal display or a shadow image display. In some embodiments, to improve the display effect and reduce the display power consumption, the display module may be an AMOLED (Active-matrix organic light-emitting diode).
The display module can comprise at least two working modes which respectively correspond to the two power supply modes of the power supply chip. For example, the power chip outputs positive 4.6 volts and negative 2.2 volts in the first mode, and one operating mode of the display module can operate normally at positive 4.6 volts and negative 2.2 volts. For another example, the power chip outputs positive 3.3 volts and negative 3.3 volts in the second mode, and one operating mode of the display module can operate normally at positive 3.3 volts and negative 3.3 volts.
In this example, the operation mode of the display module may be set to a corresponding mode in response to setting the operation mode of the power supply chip to the target operation mode. From this, can set up under the situation of operating mode at power chip, the corresponding operating mode that sets up display module assembly guarantees that display module assembly can normally work, avoids influencing user experience when setting up the power supply mode.
In some embodiments, the working parameters of the display module in different working modes are different. When the operation mode is set, the setting of the operation parameter may be performed.
The working parameter may include a working voltage, for example, at least one of a gamma (gamma) voltage and a pixel voltage, or may also include one or more of screen brightness, display saturation, and the like, and the display module may maintain a better display effect in different working modes by adjusting the working parameter.
In this example, the operating parameters of the display module may be set based on the target operating mode of the power chip. From this, can set up under the condition of mode at power chip, the corresponding working parameter who sets up display module assembly guarantees that display module assembly can normally work, avoids influencing user experience when setting up the power supply mode.
In some embodiments, the operating parameters of the display module corresponding to the target operating mode may be determined based at least in part on the current state of the display module. In some embodiments, the working parameters of the display module in different working modes can be stored through a register, so as to improve the efficiency of setting the working modes of the display module.
The display module comprises at least one parameter register; the at least one parameter register is used for storing a plurality of working parameters of the display module. The plurality of operating parameters may include at least operating parameters corresponding to the first mode and the second mode, respectively. When the working parameters of the display module are set, the working parameters corresponding to the target working mode can be obtained from the at least one parameter register; and setting the acquired working parameters as the working parameters of the display module. Therefore, the setting efficiency of the working mode of the display module can be improved.
In some embodiments, the plurality of operating parameters may be stored in a parameter register. At this time, when the working parameters of the display module are set, the working parameters corresponding to the target working mode set by the power supply chip are obtained from the parameter register. For example, the operating parameter corresponding to the operating mode may be acquired at a corresponding position of the parameter register based on the storage location information of each of the plurality of operating parameters.
In some embodiments, the plurality of operating parameters may be stored in different parameter registers. For example, the at least one parameter register includes a first parameter register and a second parameter register; the first parameter register is used for storing working parameters corresponding to the first mode; the second parameter register is used for storing working parameters corresponding to the second mode.
In this example, when setting the power chip operation mode, a target parameter memory may be determined from the at least one parameter register based on the target operation mode of the power chip; and then obtaining the working parameters from the target parameter register.
For example. The working parameters required by the display module can be stored in the first parameter register in the first mode of the power chip in advance. The working parameters required by the display module can be stored in a second parameter register in the second mode of the power chip in advance. It should be noted that the parameter register disclosed in the present application may refer to a single register or a register group having a data registering function.
When the working mode of the display module is set, the first parameter register can be determined as a target parameter register in response to setting the working mode of the power supply chip to be the first mode, and working parameters are obtained from the first parameter register to complete the setting of the working mode of the display module. And in response to the setting of the working mode of the power supply chip to a second mode, determining the second parameter register as a target parameter register, and acquiring working parameters from the second parameter register to complete the setting of the working mode of the display module. Therefore, the working parameters of the display module in different working modes can be acquired from the register, so that the working mode setting efficiency of the display module is improved, and the user experience is improved.
In some embodiments, the at least one parameter register comprises a gamma register.
