Example 1

The method embodiment provided in Embodiment 1 of the present application can be executed in a mobile terminal or a similar computing device. Taking a mobile terminal as an example, FIG. 1 is a hardware structural block diagram of a mobile terminal of a method for booting a terminal according to an embodiment of the present disclosure. As shown in FIG. 1, mobile terminal 10 may include one or more (only one shown) processor 102 (processor 102 may include, but is not limited to, a microprocessor (MCU) or a programmable logic device (FPGA), etc. The processing device), the memory 104 configured to store data, and the transmission device 106 configured as a communication function. It will be understood by those skilled in the art that the structure shown in FIG. 1 is merely illustrative and does not limit the structure of the above electronic device. For example, the mobile terminal 10 may also include more or fewer components than those shown in FIG. 1, or have a different configuration than that shown in FIG.

The memory 104 can be configured as a software program and a module for storing application software, such as program instructions/modules corresponding to the booting method of the terminal in the embodiment of the present disclosure, and the processor 102 executes by executing a software program and a module stored in the memory 104. Various functional applications and data processing, that is, the above methods are implemented. Memory 104 may include high speed random access memory, and may also include non-volatile memory such as one or more magnetic storage devices, flash memory, or other non-volatile solid state memory. In some examples, memory 104 may further include memory remotely located relative to processor 102, which may be connected to mobile terminal 10 over a network. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

Transmission device 106 is configured to receive or transmit data via a network. The above-described network specific example may include a wireless network provided by a communication provider of the mobile terminal 10. In one example, the transmission device 106 includes a Network Interface Controller (NIC) that can be connected to other network devices through a base station to communicate with the Internet. In one example, the transmission device 106 can be a Radio Frequency (RF) module configured to communicate with the Internet wirelessly.

In this embodiment, a method for booting the mobile terminal is provided. FIG. 2 is a flowchart of a method for booting a terminal according to an embodiment of the present disclosure. As shown in FIG. 2, the process includes the following steps:

Step S202, after triggering the power-on operation of the terminal, determining whether the battery voltage of the terminal is less than a preset threshold, where the preset threshold includes a voltage value capable of enabling one or more hardware modules on the terminal to be activated;

Step S204, in the case that the battery voltage of the terminal is less than a preset threshold, enabling the specified hardware module in one or more hardware modules on the terminal to be started, and reading the pre-stored target information;

Step S206, displaying the read target information to the display screen of the terminal.

If the battery voltage of the current terminal is less than a preset threshold, the preset threshold includes a starting voltage value of one or more hardware modules on the terminal, and the terminal can still be able to enable the terminal to perform the above steps S202 to S206. The specified hardware module of the one or more hardware modules on the terminal is started, and the pre-stored target information is read, thereby solving the problem that the terminal battery voltage is too low to be normally turned on in the related art, and the user is improved. The effect of the experience.

It should be noted that, in this embodiment, a preset threshold that includes a voltage value that enables one or more hardware modules on the terminal to be activated is preferably a hardware module that can be used to enable the terminal to boot normally. The starting voltage value, that is, the voltage value initiated by the one or more hardware modules is preferably one or more hardware module starting voltage values required for the terminal to be normally powered on. In other words, the preset threshold is also commonly referred to as the lowest terminal. The starting voltage value, which is the minimum voltage value required to complete the power-on action, is typically between 3.3V and 3.6V in this embodiment.

The hardware that needs to be started for the normal booting involved in the embodiment includes at least: a power management circuit, a single core in a central processing unit (CPU), a memory, a memory, and a display; It is to be noted that, in the specific embodiment of the embodiment, in the case where the battery voltage of the terminal involved in the step S204 is greater than a preset threshold, it is preferably a single in the power management circuit and the multi-core CPU in the terminal. Multiple hardware modules of the core, memory, memory, and display are initialized and powered.

It can be seen that, in the case that the battery voltage of the current terminal is less than the starting voltage value of the hardware module required to enable the terminal to be normally turned on, the terminal can still read and display the target information stored in advance, that is, without shortening the normality of the terminal. In the case of the endurance time, the user can also obtain the target information stored in advance when the terminal battery voltage is too low to be normally turned on, thereby solving the related art method of reserving part of the power amount for the terminal as the normal power-on state again. The user mistakenly believes that the current display power before the shutdown is a power that can be continuously used, resulting in a problem that the user experience is not good, and the effect of improving the user experience is achieved.

It should be noted that the execution body of the above steps may be a terminal or the like, but is not limited thereto.

In addition, the pre-stored target information involved in the embodiment of the present disclosure includes, but is not limited to, application information of one or any combination of the following: a phone book, a notepad, information, and a photo. That is, the pre-stored application involved in the embodiment is preferentially an application related to text information, and an application related to a picture. However, it should be noted that the foregoing pre-stored application is merely an example and is not limited thereto. Other applications related to text information, and applications related to the image may also be applications, such as a bookkeeping book. Calendar and more.

The following describes the manner of the foregoing embodiment by using an Android smartphone as an example;

The battery voltage in the smartphone is lower than the minimum startup voltage (preset threshold), and the low power boot process continues. Power-on and initialization of power management circuits, some CPUs (single cores in multi-core CPUs), memory, and memory in the Android Phone's Secondary Boot Loader (SBL) phase, on Android smartphones After the lk stage initializes the display, it does not continue to initialize many hardware, and does not continue to jump to the kernel and its later boot process. Instead, it enters the low after the screen initialization in the aboot init process of the lk phase. The voltage starts up and remains in the lk phase, entering the display of pre-stored application information. Because the current required for the lk phase is many times lower than the maximum current required for the subsequent boot process, the smartphone can also be used for a longer period of time at low voltages.

In the lk stage, important contents such as phone book, notebook, information, and pictures stored by the user are read by an existing function such as MMC_READ.

In an optional implementation manner of this embodiment, the manner in which the read target information is displayed on the display screen of the terminal in step S206 of the embodiment may be: according to the reading order of the read target information and Corresponding relationship between the type of the target information and the preset display mode, and the read target information is displayed to the display screen, wherein the customized format is read and displayed in the optional embodiment of the present embodiment. Display and read for the way of swiping the picture, that is, reading the picture content in a custom format and writing it directly to the display. That is to say, the manner of displaying the target in step S206 of the present embodiment is all preset in advance.

The following takes the type of the target information as the text information and the picture information as an example to display the read target information to the display screen according to the reading order of the reading target information and the correspondence between the type of the target information and the display mode. The way to explain.

When the target information is text information, the method displays the read text information according to the reading order of the read text information, the font size of the text information set in advance, and the number of lines of the text information displayed. To the display;

In the case where the target information is picture information, the method is: displaying the read text information to the display screen according to the reading order of the read picture information and the customized picture display format.

Since the information of the application program needs to be displayed under low voltage power-on in this embodiment, it is required to determine the pre-stored target information when the battery voltage of the terminal is greater than or equal to the preset threshold; and the determined target is to be determined. The information is stored in an available partition; wherein the stored target information includes: information before and/or after the application update. In order to be able to read and display information at a low voltage, the format of the displayed target information corresponds to the format of the target information stored in the newly created backup partition.

It can be seen that, in the case that the terminal is normally powered on (the battery voltage is greater than or equal to the preset threshold), it is necessary to preset which target information is stored, and the stored target information needs to be stored in the newly created backup partition or the existing available partition. In order to read these target information smoothly at low voltage.

The following uses the target information as the application information for storing the address book, the text information, and the picture as an example, and what is set as the application preset under the normal booting, and also needs to store the information determined to be the previously stored application in the newly created An example of how to back up a partition or an existing available partition;

During the normal boot operation, when the content of the address book, notebook, or other important information is detected to change, the data needs to be re-stored, either all of them may be re-stored, or the changed portion may be re-stored.

The storage operation is completed after the normal boot. After the normal boot, you can create a new backup partition, start a storage service, and write data to the partition by opening /OPEN, writing /WRITE, etc. A corresponding operational interface is provided at the application layer to invoke the hardware abstraction layer/HAL layer implementation for use when needed.

(1) Store the address book, access the address book VCF/CSF file, and simply transfer the content to the custom backup partition or the existing available partition through the interface. After each address book is stored, a carriage return character is stored as the end mark of the article. After all the content is stored, several carriage return characters are stored as the overall end mark. Of course, you can also customize other storage and reading rules.

(2) Store text information, access other important information files such as Notepad, and simply process the content and transfer it to the custom backup partition or the existing available partition through the above operation interface.

(3) Store the picture and select the picture to save to the backup partition.

In another optional implementation manner of this embodiment, after the information of the read application is displayed in step S206 of the embodiment, the method in this embodiment may further include: adopting a preset virtual key of the terminal and/or Or the physical button controls the display state of the target information. That is to say, in the present embodiment, the displayed target information can be controlled by virtual keys and/or physical keys.

In the case that the display state of the target information is controlled by the physical button, in this embodiment, the target information to be displayed on the next screen is called up through the upper volume key of the terminal, and the lower volume button is used to call up the previous screen. The target information to be displayed; or, the lower volume key is used to call up the target information to be displayed on the next screen, and the upper volume key is used to call up the target information to be displayed on the previous screen. That is, in the case of the low-voltage power-on, the information for the application with the display can be adjusted through the volume key of the terminal. In the specific application scenario of this embodiment, the following can be:

Determining whether the upper volume key of the terminal is pressed, and if pressed, outputting the next screen data of the read content to the display screen; wherein if the read content has been outputted, the content displayed on the display is maintained No change; otherwise, the current state is maintained, that is, the next screen data of the read content is output to the display. Determine whether the volume key is pressed. If it is pressed, output the previous screen data of the read content to the display. If the content read at the front is already displayed, the content displayed on the display is maintained. No change; otherwise, keep the current state unchanged, that is, output the previous screen data of the read content to the display. Among them, long press the volume button to quickly refresh the data, in order to quickly find the target content. In this way, the user can conveniently and quickly read and display the information of the application to be displayed.

In still another optional implementation manner of this embodiment, after the read target information is displayed on the display screen of the terminal in step S206 of the embodiment, the method in this embodiment may further include: displaying the target information at the current time. If the display time exceeds the first preset threshold, the display screen is turned off; if the display time of the current display target information exceeds the second preset threshold, receiving an instruction for triggering the terminal to perform the shutdown operation to perform the shutdown operation; The second preset threshold is greater than the first preset threshold.

It should be noted that, in the embodiment, the first preset threshold is preferably 30s, and the second preset threshold is preferentially 5min. Of course, the values of the first preset threshold and the second preset threshold may be based on actual conditions. The setting is not limited to the above values.

Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course, by hardware, but in many cases, the former is A better implementation. Based on such understanding, portions of the technical solution of the present disclosure that contribute in essence or to the prior art may be embodied in the form of a software product stored in a storage medium (such as a read-only memory (Read-Only).

Example 3

In the embodiment, an Android smartphone is taken as an example for illustration.

In the embodiment, by modifying the boot process, the user is provided with the required information and functions in the early booting phase of the Android smartphone. The reason for implementing the function of the scheme at an earlier stage has two advantages: (1) achievable at this stage; (2) the current consumption current at this stage is greater than the maximum supply current required for the entire boot process. A lot smaller. This will ensure that the user can use the function smoothly.

The embodiment provides a low voltage booting device, and FIG. 7 is a structural block diagram of a low voltage booting device according to an embodiment of the present disclosure. As shown in FIG. 7, the device includes:

The storage module 702 (corresponding to the storage module 44 in the embodiment 2) is configured to store information such as an address book, a notebook, and important information in a power-on state;

The startup module 704 (corresponding to the determination module 32 in the embodiment 2) is configured to be suspended when the battery voltage is lower than the normal minimum startup voltage, that is, when the battery is low, and at this time, at an earlier stage (such as the lk phase of the Android system). Continue to boot.

Because in the normal boot process, the process behind the earlier stage will consume a lot of power, and when the battery voltage is lower than the normal minimum boot voltage, the complete boot process cannot be completed. The startup module 704 does not complete the boot process. The technical solution is also implemented at an early stage of booting.

FIG. 8 is a flowchart of a method for operating a low voltage boot according to an embodiment of the present disclosure. As shown in FIG. 8, the steps of the method include:

Step S801: The user triggers the boot process;

Among them, it is preferably triggered by pressing the power button in a specific application scenario.

Step S802: At an earlier stage of the boot process, such as the lk phase initiated by the Android system, it is determined whether the battery voltage is lower than the normal boot voltage. If it is lower than the normal startup voltage, it will jump to S804; if it is higher than the normal startup voltage, it will jump to S803. The minimum turn-on voltage refers to the minimum voltage required to complete the boot operation, usually between 3.3V and 3.6V.

Step S803: The battery voltage is higher than the normal startup voltage, and the normal startup process is continued.

Step S804: the battery voltage is lower than the normal startup voltage, and the low power startup process is continued.

Among them, the power management circuit, part of the CPU, memory and memory hardware are powered on and initialized in the SBL stage. After the display is initialized in the lk stage, the hardware is not initialized and the normal jump is no longer continued. Go to the kernel and its later boot process, but after the screen initialization in the aboot init process of the lk stage, it maintains the lk phase and enters specific important information (corresponding to the applications in the above embodiments 1 and 2). The information shows that the current required by the lk phase is many times lower than the maximum current required for the subsequent boot process, so it can be used for a long time.

Step S805: In the lk stage, the important contents such as the phone book, the notebook, the information, and the picture stored by the user are read by an existing function such as MMC_READ.

Step S806: The read content is output to the display screen in sequence by the printing function, wherein the size of the font and the number of lines displayed per screen are fixed, and the format of the read and display content is corresponding to the format when the content is stored. To ensure the user experience. The content of the image format can be displayed in a brushed manner.

Step S807: It is judged whether the upper volume key is pressed, and if it is pressed, step S808 is performed; otherwise, the current state is maintained. Press and hold the volume button to quickly refresh the data to quickly find the target content.

Step S808: Output the next screen data of the read content to the display screen, wherein if the read content has been outputted, it remains unchanged.

Step S809: It is judged whether the lower volume key is pressed, and if it is pressed, step S810 is performed; otherwise, the current state is maintained.

Step S810: Outputting the previous screen data of the read content to the display screen, wherein if the foremost read content has been displayed, it remains unchanged.

Step S811: If the display screen is always on, and there is no key operation within 30 seconds, it is considered to be a display timeout state, and then step S812 is performed.

Step S812: The display screen is turned off to save power.

Step S813: If it is detected that the display screen has been extinguished for five minutes, it is considered to be a black screen running timeout state, and then step S814 is performed.

Step S814: Perform a shutdown operation to save power.

Before the step S801 to the step S814 of the present embodiment, in order to accurately display the specific important information, it is necessary to set in advance which information is specific important information after the normal power-on. In this embodiment, during normal booting, the changed information is re-stored in the corresponding partition after each boot or when other important information such as an address book or a notepad changes.

9 is a flowchart of a method for preset setting content to be displayed in a low voltage power-on state according to an embodiment of the present disclosure. As shown in FIG. 9, the steps of the method include:

Step S901: trigger the terminal to start normally.

Step S902: After detecting that the content of the address book, the notebook or other important information changes after the normal power-on, the changed data is re-stored, wherein all of the data may be re-stored, or the changed part may be re-stored.

Step S903: Start a data storage process.

Among them, the storage operation is completed after the normal boot.
