Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to correct the battery voltage value so that the intelligent sound battery can avoid the occurrence of a system shutdown or restart due to sudden power failure and completely exhaust the battery power to improve the battery power supply performance while ensuring that the sound playing volume is stabilized at a higher volume value, an embodiment of the present invention provides an optimization method for intelligent sound battery power supply, as shown in fig. 1, the method includes:
101. a first voltage value of the battery is obtained.
Wherein the first voltage value is a current voltage value of the battery. The current voltage value may be 4V, 3.2V, or the like, and specifically, this step may be a method for monitoring a voltage value of a battery in the prior art, for example, by configuring a voltage detection chip in a circuit where the battery is located, which is not described in detail in this embodiment of the present invention. Of course, in the specific implementation, the obtained value may also be other values used for identifying different states in the battery power supply process, such as the battery capacity, and is not limited thereto.
It should be noted that, the execution main body in the embodiment of the present invention may be a device configured in a circuit powered by an intelligent sound battery and used for optimizing the battery power supply, and when the device monitors that the circuit is closed to supply power to the system, it indicates that a battery voltage value needs to be monitored, and an acquisition instruction is triggered, thereby implementing optimization of the battery power supply.
102. And detecting whether the first voltage value is lower than a first preset voltage threshold value.
The first preset voltage threshold is a voltage value corresponding to the battery when the circuit of the identification sound box is powered off in a first working mode, and the first working mode is that the volume of sound played by the sound box is higher than a preset volume threshold. The first preset voltage threshold may be set in different situations, for example, when the smart audio a plays a sound with a maximum volume of 20KHz, the power supply is stopped when the battery voltage of the audio battery is 3.4V, and the first preset voltage threshold for this type of audio battery may be set to 3.4V, 3.5V, or 3.6V. Specifically, in this step, a chip may be configured in the circuit and a built-in detection function may be called to perform detection, or a preset interface may be called to perform detection, and the embodiment of the present invention is not particularly limited to this.
103. And if so, correcting the first voltage value.
Further, a second voltage value is obtained, where the second voltage value is a voltage value capable of supplying power to the sound device in the first working mode. For example, as described in step 102 above, for the battery voltage value of smart audio a, the second voltage value may be set to 3.4V, or 3.5V, etc. to ensure that the battery can support the system to continue stable operation at a higher playback volume when the battery voltage value is corrected to the second voltage value. Specifically, in this step, the current voltage value of the battery may be boosted to obtain the second voltage value, so that when the voltage value of the battery of the smart audio decreases to the first voltage value and cannot continuously and stably operate under the condition of high playing volume, the first voltage value is corrected to the second voltage value and then power is continuously supplied to the power utilization element until the voltage of the battery decreases to the discharging cut-off voltage.
The invention provides an optimization method for battery power supply of an intelligent sound, which solves the problem of poor battery power supply performance caused by the situation that partial battery energy is wasted and the volume of played sound is lost by increasing the minimum working voltage of a system or actively reducing the gain of an audio power amplifier when the voltage value of a battery is low to avoid the situation that the system is powered off or restarted when the voltage value of the battery is too low in the battery power supply process in the prior art, and aims to solve the problems that the battery power supply performance is poor by acquiring the current voltage value of the battery and detecting the current voltage value, when the current voltage value of the battery is detected to be lower than a preset voltage threshold value, namely when the battery cannot supply power to the sound playing volume to exceed the preset volume threshold value, the battery voltage is triggered to be corrected so that the battery voltage is increased to be capable of continuously supplying power under the condition that the sound playing volume is stable until the battery energy is exhausted, compared with the prior art, the battery voltage can be corrected, so that the battery can continuously supply power until the energy of the battery is exhausted under the condition that the volume of the sound equipment is stable at a high volume value, the waste of the energy of the battery is avoided, the problem of volume loss of the sound equipment is avoided, and the power supply performance of the battery is improved.
Further, as a refinement and an extension of the embodiment shown in fig. 1, the embodiment of the present invention further provides another method for optimizing the power supply of the smart audio battery, as shown in fig. 2.
201. A first voltage value of the battery is obtained.
Wherein the first voltage value is a current voltage value of the battery. The first voltage value and the specific implementation of this step can refer to the corresponding descriptions in step 101, and are not described herein again.
202. And detecting whether the first voltage value is lower than a first preset voltage threshold value.
The first preset voltage threshold is a voltage value corresponding to the battery when the circuit of the identification sound box is powered off in a first working mode, and the first working mode is that the volume of sound played by the sound box is higher than a preset volume threshold. Specifically, the conceptual explanation of the first preset voltage threshold and the specific implementation of this step can refer to the corresponding description in step 102, and are not repeated herein.
It should be noted that the detection in this step may be to continuously detect the battery voltage in real time in the whole battery power supply process, may also be to detect the battery voltage value according to a preset time interval in the battery power supply process, and may also be to detect the battery voltage when it is detected that the sound playing volume suddenly appears in a high-pitch component, and the like, which is not specifically limited in this embodiment of the present invention.
203. And if the first voltage value is lower than a first preset voltage threshold value, triggering and starting a preset boost converter.
Specifically, this step may be to configure a voltage booster with bypass function in the circuit, so that when the current voltage value of the battery is lower than a first preset voltage value, the voltage booster with bypass function is triggered to start, and a specific starting manner of the preset voltage booster may be, for example, a mode triggered to start by a comparator, a mode triggered to start by General Purpose input/output (General Purpose input/output), and the like in the prior art, which is not described in detail in this embodiment of the present invention.
For the embodiment of the present invention, when it is detected in step 202 that the current voltage value of the battery has decreased to the first preset voltage threshold, it indicates that the battery voltage value does not reach the discharge cut-off voltage value, but the battery will be forced to stop supplying power when the energy is not exhausted due to the continuous or sudden high volume playing of music. Therefore, in the step, the booster which is configured in advance in the circuit is triggered to be started, so that the situation that in the later battery discharging process, the continuously reduced battery voltage is increased through the booster, the circuit can be continuously supplied with power, the intelligent sound box can support continuous or sudden high-volume playing until the battery voltage value is reduced to the discharging cut-off voltage value of the battery, and the battery power supply performance is further improved.
204. And converting the first voltage value into the second voltage value and outputting the second voltage value.
The second voltage value is a voltage value capable of supplying power to the sound in the first working mode. The second voltage value may be set according to an actual situation, for example, set as a knee point voltage of a lithium battery discharge curve of the smart audio. Specifically, the step may be to set the output voltage of the booster to the second voltage value in advance, and after the booster is triggered to be turned on, use the first voltage value of the current voltage of the battery as the input voltage of the booster, and then convert the second voltage value by the booster and output the converted second voltage value. In practical application, a boost converter chip with wide voltage input can be selected, that is, the minimum input voltage of the boost converter is lower than the first preset voltage threshold of the battery, so that the boost converter can be triggered to be started and the current voltage value of the battery can be corrected when the voltage of the battery is reduced to any low value. For example, when the voltage value of the battery of the intelligent sound equipment is lower than 3.6V, the sound equipment plays music with the maximum volume, the voltage of the battery drops or shakes to the minimum voltage value of 3.3V, and the minimum working voltage of the boost converter with the boost bypass function configured in the power supply circuit of the intelligent sound equipment is smaller than 3.3V, such as 3.0V or lower, so that the boost converter can work normally even if the voltage of the battery drops or shakes to 3.3V, and the stable output voltage is provided for the continuous and stable operation of the system.
It should be noted that, by configuring the voltage booster with a bypass function in the circuit, when the battery voltage value is higher than the first preset voltage threshold, the voltage booster is in an open circuit state, at which the battery output voltage is directly supplied to the power consuming element in the circuit, and when it is detected that the battery voltage value is lower than the preset voltage threshold, i.e. the battery is in a low battery state, the connection of the voltage booster is triggered and the battery output voltage value is corrected to the second voltage value, thereby enabling the battery to continue to stably supply power to the circuit until the battery energy is exhausted.
According to the embodiment of the invention, the current voltage of the battery is used as the input voltage of the booster, and then the current voltage is converted and output by the booster to keep the circuit working voltage value of the sound playing volume value, and the power can be continuously and stably supplied until the electric quantity of the circuit is completely exhausted, so that the full utilization of the electric energy of the battery and the stability of the volume value of the sound are realized, and the power supply performance of the battery is improved.
205. And acquiring the current residual capacity of the battery.
The remaining capacity of the battery may be 600mAh or 400mAh, and specifically, in this step, an electricity meter or the like may be configured in a circuit where the battery is located, or a chip with a function of measuring the capacity of the battery is configured, which is not specifically limited in this embodiment of the present invention.
206. And calculating the residual power supply time corresponding to the battery according to the current residual capacity and outputting prompt information.
The prompt information may be text information, picture information, audio information, and the like, and may be specifically set according to different application scenarios, for example, when the intelligent sound equipment is configured with a display screen, the text prompt information or the picture prompt information may be output in the display screen, and when the intelligent sound equipment is not configured with a display screen, the voice prompt information may be output.
In addition, in the embodiment of the present invention, the smart audio may be associated with the mobile terminal device, and the prompt information is output from the mobile terminal device, and the association manner between the smart audio and the mobile terminal device may be bluetooth connection, or association by logging in the same user account, and the like, which is not specifically limited in the embodiment of the present invention. For example, the smart sound is associated with the smart watch through bluetooth, and when the remaining power supply time of the smart sound is calculated to be 1 hour and 12 minutes according to the current remaining capacity of the smart sound, the text prompt message "remaining standby time" is output in the smart watch of the associated device of the smart sound at the moment: 01: 12 ".
Specifically, this step may be to calculate the amount of power that can be supplied to the elements in the circuit from the current remaining capacity of the battery and the conversion rate of the booster, and then calculate the remaining power supply time in conjunction with the power loss of the power-using elements. For example, in the process of supplying power to the battery, the current remaining capacity of the battery is 600mAh, and the conversion rate of the booster is 85%, then the electric energy provided to the intelligent household appliance in the circuit after conversion by the booster is 600mAh × 85% — 510mAh, and when the average power consumption of the intelligent household appliance is 300mA, the remaining power supply time that the battery can continuously supply power is calculated as 510mAh ÷ 300mA ≈ 1.7 hours.
For the embodiment of the invention, after the booster is triggered to be started, the residual power supply time of the battery is calculated and prompt information is output, so that a user can acquire the power supply condition of the battery in time and take corresponding measures, the problem of inconvenient use of the user caused by sudden power failure of the battery is avoided, and the use experience of the user is greatly improved.
207. And when the first voltage value is lower than a second preset voltage threshold value, stopping power supply is triggered.
And the second preset voltage threshold is the discharge cut-off voltage value of the battery. The second preset voltage threshold may be set according to conditions of different batteries, which is not specifically limited in the embodiment of the present invention. It should be noted that, when the voltage value of the battery reaches the discharge cut-off voltage of the battery, it indicates that the battery cannot continue to supply power, and at this time, the electric energy in the battery is completely consumed, so in this step, when it is detected that the voltage value of the battery is reduced to the discharge cut-off voltage, the power supply is stopped by triggering, thereby avoiding the problem of shortening the service life of the battery due to the excessive use of the battery, and thus improving the safety of the use of the battery.
Further, according to the method described in step 201-207, in combination with the circuit structure diagram shown in fig. 3, an embodiment of the present invention may further provide an implementation manner for optimizing power supply to the smart sound battery in combination with a specific application scenario, where the implementation process is divided into five execution steps, specifically, as follows:
in the first step, a boost converter is arranged between a Power Management IC (Power Management IC) and a Power supply battery of the smart audio a, and an input voltage value of the boost converter ranges from 3.0V to 5.0V.
And secondly, when the battery of the sound equipment is in a low-power state, the audio power amplifier enables the voltage of the battery to drop to 3.3V, and the preset boost converter with bypass function is triggered and started by detecting the current voltage value of the battery and when the voltage of the battery is detected to drop to 3.4V.
And thirdly, gradually reducing the current value of the battery, taking the current voltage value of the battery as the input voltage of the boost converter, converting the current voltage value of the battery, and outputting a preset output voltage value 3.7V capable of supporting the work of the PMIC, thereby realizing the continuous power supply of the circuit when the voltage value of the battery is reduced from the power-off voltage 3.3V to the discharge cut-off voltage 3.0V.
And fourthly, when the boost converter is triggered and started, the current residual electric quantity of the battery is 500mAh, the electric quantity which can be provided for the circuit by the battery is 500mAh by 90 percent which is 450mAh according to the preset conversion efficiency of 90 percent, the residual power supply time of the battery is 1.5 hours and prompt information is output by combining the calculation of the average power consumption of the intelligent sound A which is 300 mA.
And fifthly, when the current voltage value of the battery is detected to reach the power supply cut-off voltage of the battery, triggering to stop the boost converter and the battery to work, and cutting off the circuit.
However, it should be noted that the specific implementation described in the above application scenarios is only an example, and is not the only specific implementation of the embodiment of the present invention, and is only one of the optimized implementations of the method according to the present invention.
