In order to save battery power, a common design is to automatically shut down after a few hours of non-use. This method can save power to a certain extent, but after the dictionary pen automatically shuts down, the user needs to restart it every time he wants to use it, and the waiting time for restart is also very long, which makes it impossible for the user to use the dictionary pen and solve the current problem he is facing as soon as he gets it.

[0036] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0037] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first" and "second" are used to distinguish the same items or similar items with substantially the same functions and effects. For example, the first instruction and the second instruction are to distinguish different user instructions, and their order is not limited. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit them to be different.

[0038] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0039] In addition, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0040] With the continuous development of computer technology, the application of intelligent electronic devices is becoming more and more extensive. For example, dictionary pens are very popular among users. Dictionary pens are a portable digital tool for language query. There is no limit on the type of books. You can read any words. It is a very powerful tool. Chinese words have stroke order, pinyin, structure, word group, sentence formation, homophones, etc.; idioms have allusions, sources, translations, synonyms and antonyms, etc.; ancient poems have translations, backgrounds, poet introductions, etc.; English has translations, phonetic symbols, examples, etc. In simple terms, a dictionary pen is a collection of many reference books on a pen, and it is not restricted by the Internet and can be used at any time.

[0041] Taking dictionary pens as an example, the dictionary pens currently on the market are usually not very large in size, so the battery capacity is small. In order to save battery power, the general design is to automatically shut down after a few hours of non-use, where the several hours can be set to 1 hour, 2 hours, 4 hours or 8 hours.

[0042] Although the above solution can save power to a certain extent by shutting down the dictionary pen when the user is not in use, after the dictionary pen automatically shuts down, the user needs to restart it every time he wants to use it. The waiting time for restart is also very long, generally more than 10 seconds. The user cannot use the dictionary pen as soon as he gets it and solve the problem he is currently facing, which greatly affects the user experience.

[0043] Therefore, how to save battery consumption of electronic devices while ensuring that users can use them immediately has become a technical problem that needs to be solved urgently.

[0044] In view of this, the embodiments of the present application provide a standby control method, device and storage medium. In the technical solution of the present application, when the electronic device is in the first standby state, the electronic device detects the duration of the electronic device in the first standby state, and then controls the electronic device to enter the second standby state when the duration of the electronic device in the first standby state is greater than the preset time threshold, and the power consumption of the first standby state is greater than the power consumption of the second standby state; wherein, in the first standby state, the electronic device is powered by the central processing unit CPU, and in the second standby state, the electronic device is powered by the step-down circuit included in the electronic device. In the standby control method, when the electronic device is in the first standby state for a period of time greater than the preset time threshold, the electronic device is controlled to enter the second standby state, and the electronic device is powered by the step-down circuit in the second standby state. The power supply of the step-down circuit can turn off the peripherals of the electronic device, thereby saving the battery consumption of the electronic device while ensuring that the user can use it as soon as possible, and achieving the effect of power saving and long battery life of the whole machine.

[0045] It should be understood that the electronic devices involved in the embodiments of the present application may be dictionary pens, point-reading pens, mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, smart screens, artificial intelligence (AI) speakers, headphones, terminals in industrial control, terminals in self-driving, terminals in remote medical surgery, terminals in smart grids, terminals in transportation safety, terminals in smart cities, terminals in smart homes, personal digital assistants (PDAs), etc., and the specific embodiments of the present application are not limited to this.

[0047] The processor 110 is the control center of the electronic device, and uses various interfaces and lines to connect various parts of the entire electronic device.

In other embodiments of the present application, the electronic device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently.

[0057] In order to make the purpose and technical solution of the present application clearer and more intuitive, the standby control method, device and storage medium provided by the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] Please refer to Figure 2 , is a flow chart of a standby control method provided by an embodiment of the present application. The method can be applied to Figure 1 The electronic equipment shown is described in detail below Figure 2 The various steps in the method shown in the flowchart include:

[0059] S201: When the electronic device is in a first standby state, detect a time length for which the electronic device is in the first standby state.

[0060] Wherein, in the first standby state, the electronic device is powered by a central processing unit (CPU).

[0061] Exemplarily, the first standby state generally refers to an electronic device entering the screen-off state after no operation for a period of time when the screen is on and no tasks are running in the background, or entering the screen-off state by a short press, etc. This application does not specifically limit this.

[0062] In some embodiments, when the electronic device is in the first standby state, it is powered by the CPU and can promptly respond to screen operations, button operations, and notification operations of the electronic device, among which screen operations include double-clicking to turn on the screen, button operations include short pressing the power button, and notification operations include pop-up reminders.

[0063] It should be understood that when the electronic device is powered by the CPU in the first standby state, the power consumption is relatively high because the peripherals of the electronic device may still be turned on.

[0064] In a possible implementation, when the electronic device is in the first standby state, the length of time the electronic device is in the first standby state can be detected by its own sensor, and the length of time the electronic device is in the first standby state can be detected with the help of other devices. This application does not specifically limit this.

[0065] S202: When the duration of the electronic device in the first standby state is greater than a preset time threshold, control the electronic device to enter a second standby state, and the power consumption of the first standby state is greater than the power consumption of the second standby state.

[0066] Wherein, in the second standby state, the electronic device is powered by a step-down circuit included in the electronic device.

[0067] In some embodiments, when the time duration that the electronic device is in the first standby state is greater than a preset time threshold, it indicates that the electronic device may be temporarily unused, so the electronic device is further controlled to enter the second standby state. It should be understood that the electronic device in the second standby state is still in a state where the screen is off and there are no tasks in the background.

[0068] It should also be understood that the power consumption of the electronic device in the first standby state is greater than that in the second standby state, and the power supply method of the electronic device in the second standby state is different. For example, the electronic device is powered by a step-down circuit in the second standby state.

[0069] The buck circuit is used to convert high voltage input into low voltage output to meet the requirements of various electronic devices for different voltage levels. For example, the output voltage of a high voltage battery or power adapter can be reduced to the operating voltage range required by chips, processors and other electronic components.

[0070] In this embodiment, when the electronic device is in the first standby state for a period longer than a preset time threshold, the electronic device is controlled to enter the second standby state, and the electronic device is powered by a step-down circuit in the second standby state. The use of the step-down circuit will reduce the power supply voltage to the electronic device, and then turn off the peripherals of the electronic device, thereby saving the battery consumption of the electronic device while ensuring that the user can use it as soon as possible, thereby achieving the effect of saving power and extending the battery life of the entire device.

[0071] Based on the above embodiments, Figure 3 A flowchart of a standby control method provided by another embodiment of the present application is described in detail below. Figure 3 The various steps in the method shown in the flowchart include:

[0072] S301, obtaining a device state of the electronic device, where the device state includes whether the electronic device is in a screen-on state, a screen-off state, or a power-off state, where the screen-off state includes a screen-off state with a background task or a screen-off state with no background task.

[0073] It should be understood that the screen-on state generally refers to the state in which the screen of the electronic device is lit, and there may be operations or tasks running on the screen or no operations, etc. The screen-on state of the electronic device can also be understood as the state in which the electronic device is in use. The screen-off state includes the screen-off and background task state or the screen-off and background no task state, where the task can be a download task or a playback task, etc. The screen-off and background task state can also be understood as the state in which the electronic device is in use, and the screen-off and background no task state can be understood as the standby state.

[0074] In some embodiments, the electronic device may detect and obtain the device status through its own tools, or may obtain the device status with the help of other devices, which is not limited in this application.

[0075] S302: When the device is in the screen-off state and there is no background task, determine that the electronic device is in the first standby state.

[0076] For example, the screen-off state can be that the electronic device automatically enters the screen-off state when there is no operation for a period of time when the screen is on, or enters the screen-off state by a short press, or enters the screen-off state by voice control, or enters the screen-off state by gesture operation, etc. The specific method is not limited in this application. Further, when entering the above-mentioned screen-off state and there is no task in the background, it is determined that the electronic device is in the first standby state.

[0077] In some embodiments, when the electronic device is in a first standby state, the peripherals of the electronic device are in an on state, for example, the Bluetooth of the electronic device is in an on state, or the network of the electronic device, such as wireless fidelity (WiFi), is in an on state. In this first standby state, the electronic device still powers various components through the CPU, and can respond to screen operations, button operations, and notification operations of the electronic device in a timely manner, among which screen operations include double-clicking to turn on the screen, button operations include short pressing the power button, and notification operations include pop-up reminders.

[0078] In a possible implementation, the operation of the electronic device entering the shutdown state may be long pressing the power button, or voice control, or gesture control, etc., and the specific method is not limited in this application.

[0079] S303: When the electronic device is in the first standby state, detect the duration of the electronic device being in the first standby state.

[0080] In a possible implementation, when the electronic device is in the first standby state, the length of time the electronic device is in the first standby state can be detected by its own sensor, and the length of time the electronic device is in the first standby state can be detected with the help of other devices. This application does not specifically limit this.

[0081] S304: When the duration of the electronic device in the first standby state is greater than a preset time threshold, control the electronic device to enter a second standby state, and the power consumption of the first standby state is greater than the power consumption of the second standby state.

[0082] In the first standby state, the electronic device is powered by the CPU, and in the second standby state, the electronic device is powered by the step-down circuit included in the electronic device.

[0083] Among them, when the electronic device is in the second standby state, the peripherals of the electronic device are in a turned-off state, for example, WiFi and Bluetooth of the electronic device are in a turned-off state. The peripherals are in a turned-off state to save battery consumption.

[0084] As an example, the preset time threshold may be set to 1 hour or 2 hours, or other values, which are not specifically limited in this application.

[0085] In a possible implementation, the electronic device further includes a low-power memory, the step-down circuit is connected to a battery of the electronic device and the low-power memory, the low-power memory is connected to a peripheral device, and an operating voltage of the low-power memory is lower than an operating voltage of the peripheral device.

[0086] For example, an exemplary structural diagram of a step-down circuit connected to a battery and a low-power memory of an electronic device is shown in FIG. Figure 4 shown.

[0087] It should be understood that the low-power memory is also connected to peripherals, such as Bluetooth or WiFi, and can be used to send voltage to Bluetooth or WiFi.

[0088] In some implementations, an implementation method of powering an electronic device through a step-down circuit is as follows: powering a low-power memory through a step-down circuit, so that the low-power memory sends a power signal with a voltage lower than the operating voltage of the peripheral to the peripheral at a preset frequency, so that the peripheral is in a closed state. In other words, the electronic device powers the low-power memory through the step-down circuit, and then uses the self-refresh capability of the low-power memory to cut off the power of the peripheral of the electronic device.

[0089] Exemplarily, the low power memory is low power double data rate SDRAM (LPDDR). For example, LPDDR4x can be used in the embodiment of the present application. The operating voltage of LPDDR4x is about 1.1 volts, which is the lowest power consumption storage solution suitable for large-screen smartphones and tablets, and high-performance network systems.

[0090] In some embodiments, the step-down circuit may be a BUCK circuit, which is a DC-to-DC converter based on the principle of inductive energy storage, and applies the basic principles of electromagnetic induction and electric energy conversion in physics. In the BUCK circuit, the DC voltage provided by the input power supply is converted into an adjustable low-voltage output by controlling the on and off states of the switching tube by controlling the input duty cycle of a pulse width modulation (PWM) wave. This can meet the power supply requirements of different circuits.

[0091] For example, the basic topology of the BUCK circuit is as follows: Figure 5As shown in FIG. 1 , the BUCK circuit includes a switch tube Q, a capacitor C, an inductor L, a load R, a diode D and a power supply Vin. The connections of each device are as follows: Figure 5 shown.

[0092] The working principle of BUCK can be divided into four stages: the on stage, the off stage, the free-wheel oscillation stage and the repetition stage. In the on stage, when the switch tube Q is turned on, the inductor L stores electrical energy and the capacitor C is charged; in the off stage, when the switch tube Q is turned off, the energy between the inductor L and the capacitor C is transferred to the load R, and the current in the inductor L still exists at this time, and it will continue to flow to the load R; in the free-wheel oscillation stage, after the current of the inductor L flows to the load R, the switch tube Q is turned off, and the current in the inductor L cannot disappear immediately, so the energy in the inductor L will be reversed back to the switch tube Q, driving the diode D to turn on, and this process is called free-wheel oscillation; in the repetition stage, the above three stages are repeated, and the duty cycle of controlling the conduction of the switch tube Q can be adjusted by the PWM controller, thereby achieving stable regulation of the output voltage.

[0093] Specifically, when the inductor in the BUCK circuit is in the on state, it converts the current through the magnetic field of the inductor's center core into magnetic energy and stores the magnetic energy in the inductor; when it is in the off state, due to the self-inductance of the inductor, the magnetic field will generate voltage, converting electromagnetic energy into electrical energy, and supplying power to the load through the output end. Therefore, by controlling the on and off states of the switch tube, the periodic conversion and regulation of electrical energy between the capacitor and the inductor is achieved, and a stable DC voltage is finally output.

[0094] In addition, the capacitor in the BUCK circuit plays a role in smoothing the output voltage by storing electrical energy when the switch is on and releasing it when it is off, thereby smoothing the output voltage fluctuation. At the same time, in order to ensure a stable output voltage, the BUCK circuit usually adopts negative feedback control, sampling the output voltage and feeding it back to the microcontroller, which then adjusts the duty cycle of the output PWM wave and controls the on and off time of the switch, so that the output voltage remains within a predetermined range.

[0095] In simple terms, the electronic device supplies power to the low-power memory through the BUCK circuit, and then uses the self-refresh capability of the low-power memory to cut off the power of the electronic device's peripherals, thereby saving the battery consumption of the electronic device and achieving the effect of saving power and extending the battery life of the entire device.

[0096] S305: Receive a wake-up operation on the electronic device.

[0097] In some embodiments, the wake-up operation may be a short press of the power button of the electronic device, or voice wake-up, or gesture wake-up, etc., which is not limited in this application. For example, the voice of voice wake-up may be a preset sentence or a word, and the gesture may be a circle drawing gesture, or a three-finger screen swiping gesture, etc.

[0098] S306, in response to the wake-up operation, controlling the peripherals of the electronic device to recover to the state of the peripherals in the first standby state, and controlling the screen of the electronic device to be in a bright screen state.

[0099] Understandably, the electronic device wakes up the electronic device in response to the above-mentioned wake-up operation, and controls the peripherals of the electronic device to restore to the state of the peripherals in the first standby state, for example, automatically synchronizing the connection states of WiFi, Bluetooth, etc. to the state in the first standby state, and then the screen can be turned on to ensure that the user can use it in time.

[0100] Optionally, in response to the wake-up operation, the electronic device may also only control the peripherals of the electronic device to recover to the state of the peripherals in the first standby state, and the screen may remain in the screen-off state, and the screen may be turned on when the user uses it.

[0101] In some embodiments, taking the electronic device as a dictionary pen as an example, after experimental testing, the test data shows that the current of the dictionary pen in the first standby state is about 4 to 5 mA. After using the standby control method in this embodiment, that is, when the duration of the dictionary pen in the first standby state is greater than the preset time threshold, the dictionary pen is controlled to enter the second standby state. After the second standby state is powered by the step-down circuit, all peripherals of the dictionary pen (such as WiFi, Bluetooth, etc.) will be turned off, and the power consumption of the machine is relatively small. The current in the dictionary pen is about 0.4 mA, which is one tenth of the current of the dictionary pen in the first standby state. At the same time, it only takes 800ms to start the dictionary pen in the second standby state, which is very fast and does not affect user use.

[0102] In this embodiment, the electronic device first obtains the device state of the electronic device, and when the device state is the screen-off state and there is no task in the background, it is determined that the electronic device is in the first standby state, and then when the electronic device is in the first standby state, the duration of the electronic device in the first standby state is detected, and then when the duration of the electronic device in the first standby state is greater than the preset time threshold, the electronic device is controlled to enter the second standby state, and the power consumption of the first standby state is greater than the power consumption of the second standby state. Finally, a wake-up operation of the electronic device is received, and in response to the wake-up operation, the peripherals of the electronic device are controlled to be restored to the state of the peripherals in the first standby state, and the screen of the electronic device is controlled to be in the bright screen state. In the standby control method, when the duration of the electronic device in the first standby state is greater than the preset time threshold, the electronic device is controlled to enter the second standby state, and the electronic device is powered by a step-down circuit in the second standby state. The power supply of the step-down circuit can turn off the peripherals of the electronic device, and the current in the electronic device is extremely low, so as to save the battery consumption of the electronic device while ensuring that the user can use it immediately, so as to achieve the effect of power saving and long battery life of the whole machine, and improve the user experience.
