Description

Electronic equipment and alarm clock processing method

Technical Field

The present application relates to the field of computing device technologies, and in particular, to an electronic device and an alarm clock processing method.

Background

At present, electronic equipment such as a mobile phone and the like can realize the function of an alarm clock. The user may replace a separate alarm clock with the alarm clock function of the electronic device.

However, as more and more applications can be installed and used on the electronic device, the power consumption of the electronic device gradually increases, which easily causes the electronic device to be powered off due to too low power when the alarm time set by the user is not reached. For example, a user sets an alarm clock at 7:00 a.m. on a mobile phone, and when the user has a rest at night, the mobile phone is in a standby state, and an application program running in a background can continue to consume power, which easily causes the mobile phone to be turned off due to too low power. When the mobile phone is in a power-off state, the RTC (real Time clock) real-Time clock chip can run all the Time, and when the current Time reaches 7:00 in the morning, the RTC chip can trigger the mobile phone to be powered on so as to start the alarm clock. However, in the process of starting up, the mobile phone cannot be normally started up and is turned off again because the mobile phone is in a low power state. Because the alarm clock is not processed, the RTC chip can trigger the mobile phone to be started again after the mobile phone is powered off.

In the above process, the electronic device enters a cycle of repeatedly turning on and off the electronic device until the electric quantity of the power module of the electronic device is completely exhausted.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. 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 application.

It should be noted that the following application scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions in the embodiments of the present application, and do not constitute limitations on the technical solutions provided in the embodiments of the present application, and it is obvious to a person skilled in the art that the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems with the occurrence of new application scenarios.

In the prior art, if the electronic device is powered off due to too low electric quantity after the user sets the alarm clock, and the alarm clock reaches the time set by the user, the real-time clock chip triggers the electronic device to be powered on to start the alarm clock. The process of the real-time clock chip triggering the electronic device to start up is shown in fig. 1, and includes the following steps:

and step S101, receiving an operation instruction of setting an alarm clock by a user, and storing the alarm clock time set by the user.

And S102, controlling the electronic equipment to enter a shutdown state when the residual electric quantity of the power supply module is monitored to be lower than a set threshold value.

Step S103, judging whether the alarm clock time set by the user is reached; if yes, go to step S104; if not, the process returns to step S103.

And step S104, controlling the electronic equipment to start.

When the electronic equipment is in a shutdown state, the power supply module of the electronic equipment still keeps certain residual electric quantity to supply power to the real-time clock chip, so that the real-time clock chip can normally time, and when the real-time clock chip monitors that the alarm clock time set by a user arrives, a startup interrupt signal is sent to an application processor of the electronic equipment to wake up the application processor. The application processor starts an operating system to control the electronic equipment to start.

In step S105, the power module cannot provide enough power-on voltage to control the electronic device to power off, and the process returns to step S103.

In the process of starting up, the electronic equipment cannot be normally started up and is shut down again because the electronic equipment is in a low-power state. Because the alarm clock is not processed, after the electronic device is shut down, the real-time clock chip can trigger the electronic device to be started again, so that the electronic device enters a cycle of starting and shutting down until the electric quantity of a power supply module of the electronic device is completely exhausted, and components such as the real-time clock chip and the like which can normally work in a shutdown state of the electronic device cannot normally work, so that electric energy is consumed, and hardware resources of the electronic device are possibly damaged. And if the electric quantity of the power supply module is completely exhausted, when the power supply module is charged again, a long time is consumed to enable the electric quantity of the power supply module to reach the minimum electric quantity capable of starting the electronic equipment.

In order to solve the problems in the prior art, an embodiment of the present application provides an electronic device and an alarm clock processing method, where when the electronic device is in a power-off state, a real-time clock chip monitors that an alarm clock time set by a user arrives, and sends a power-on interrupt signal to an application processor to wake up the application processor. The application processor receives a starting-up interrupt signal sent by the real-time clock chip, detects the voltage of the power supply module, and if the voltage of the power supply module is lower than the starting-up voltage of the electronic equipment, the alarm clock function is closed, so that the real-time clock chip is prevented from waking up the application processor again and trying to start up the electronic equipment, and the electronic equipment is prevented from consuming electric energy due to the fact that the electronic equipment enters a cycle of repeated starting-up and shutdown.

The electronic equipment in the embodiment of the application can be mobile phones, wearable equipment, tablet computers and other electronic equipment with an alarm clock function.

Fig. 2 shows a schematic structural diagram of an electronic device 200 according to an embodiment of the present application. As shown in fig. 2, the electronic device 200 may include an application processor 201, a memory 202, a real-time clock chip 203, and a power module 204.

The real time clock chip 203 is used for timing. Generally, when the electronic device is in the power-off state, the application processor 201 is completely powered off, and the real-time clock chip 203 is not powered off, but can continue to count time, and when the alarm clock time set by the user is reached, a power-on interrupt signal is sent to the application processor 201 to wake up the application processor, so that the electronic device is powered on and activates the alarm clock and rings.

In an alternative embodiment, when the electronic device 200 is a communication terminal, the electronic device 200 may further include a bb (base band) baseband module, and the real-time clock chip 203 may be a part of the baseband module of the electronic device. For example, the baseband module may include a baseband processor and a real time clock chip 203. When the real-time clock chip 203 monitors that the alarm clock time set by the user arrives, a power-on interrupt signal can be sent to the application processor 201 through the baseband processor to wake up the application processor 201.

The application processor 201, i.e., the CPU module, may include one or more single-chip microcomputers, microprocessors, digital processing units, or the like. The application processor 201 may implement the above-described alarm clock processing method when calling a computer program stored in the memory 202 of the electronic device. Such as: after receiving the power-on interrupt signal sent by the real-time clock chip 203, the voltage of the power module 204 is detected, and if the voltage of the power module 204 is lower than the power-on voltage of the electronic device, the alarm clock function is turned off, so that the real-time clock chip 203 is prevented from waking up the application processor again and trying to turn on the electronic device, and the electronic device is prevented from consuming electric energy due to entering a cycle of repeated power-on and power-off.

The specific connection medium among the application processor 201, the memory 202 and the real-time clock chip 203 is not limited in the embodiments of the present application.

The following specifically describes the embodiments of the present application by taking the mobile phone 300 as an example. It should be understood that the handset 300 shown in fig. 3 is merely an example, and that the handset 300 may have more or fewer components than shown in fig. 3, may combine two or more components, or may have a different configuration of components. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

A block diagram of a hardware configuration of a handset 300 according to an exemplary embodiment is illustrated in fig. 3. As shown in fig. 3, the mobile phone 300 includes: radio Frequency (RF) circuitry 310, a baseband module 320, a display unit 330, a sensor 340, audio circuitry 350, a Wireless Fidelity (Wi-Fi) module 360, an application processor 370, a memory 380, and a power supply 390.

The RF circuit 310 may be used for receiving and transmitting signals during information transmission and reception or during a call, and may receive downlink data of a base station and then send the downlink data to the application processor 370 for processing; the uplink data may be transmitted to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, and the like.

Memory 380 may be used to store software programs and data. The application processor 370 performs various functions of the cellular phone 300 and data processing by executing software programs or data stored in the memory 380. The memory 380 may include high speed random access memory and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device. The memory 380 stores an operating system that enables the handset 300 to operate. The memory 380 may store an operating system and various application programs, and may also store codes for performing the methods described in the embodiments of the present application.

The display unit 330 may be used to receive input numeric or character information and generate signal input related to user settings and function control of the mobile phone 300, and specifically, the display unit 330 may include a touch screen 331 disposed on the front surface of the mobile phone 300 and capable of collecting touch operations of the user thereon or nearby, such as clicking a button, dragging a scroll box, and the like.

The display unit 330 may also be used to display information input by the user or information provided to the user, and a Graphical User Interface (GUI) of various menus of the mobile phone 300. Specifically, the display unit 330 may include a display screen 332 disposed on the front surface of the cellular phone 300. The display screen 332 may be configured in the form of a liquid crystal display, a light emitting diode, or the like. The display unit 330 may be used to display the current time and to set a graphical user interface for alarm clock use, etc.

The touch screen 331 may be covered on the display screen 332, or the touch screen 331 and the display screen 332 may be integrated to implement the input and output functions of the mobile phone 300, and the integrated function may be referred to as a touch display screen for short.

The handset 300 may also be configured with other sensors such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, light sensors, motion sensors, and the like.

The audio circuit 350 may transmit the electrical signal converted from the received audio data to the speaker 351, and convert the electrical signal into a sound signal by the speaker 351 and output the sound signal. The handset 300 may also be configured with a volume button for adjusting the volume of the sound signal. On the other hand, the microphone 352 converts the collected sound signals into electrical signals, which are received by the audio circuit 350 and converted into audio data, which are then output to the RF circuit 310 for transmission to, for example, another terminal, or to the memory 380 for further processing. In the present application, the microphone 352 may capture the voice of the user.

Wi-Fi belongs to short-distance wireless transmission technology, and the mobile phone 300 can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the Wi-Fi module 360, and provides wireless broadband internet access for the user.

The handset 300 also includes a power module 390 (e.g., a battery) that provides power to the various components. The power module 390 may be logically connected to the application processor 370 through the baseband module 320, so as to implement functions of managing charging, discharging, and power consumption. The mobile phone 300 may also be configured with a power button for powering the mobile phone on and off, and locking the screen.

The baseband module 320, namely BB module, is the basic circuit part of the handset 300, and includes a baseband processor 321 and a real-time clock chip 322, the baseband processor 321 is used for processing wireless communication, and the real-time clock chip 322 is used for timing. When the handset is in the off state, the application processor 370 is completely powered off, and the real-time clock chip 322 of the baseband module 320 is not powered off, and can still keep timing.

The application processor 370 is a control center of the mobile phone 300, connects various parts of the entire terminal using various interfaces and lines, and performs various functions of the mobile phone 300 and processes data by running or executing software programs stored in the memory 380 and calling data stored in the memory 380. In some embodiments, applications processor 370 may include one or more processing units. In the present application, the application processor 370 may run an operating system, an application program, a user interface display, and a touch response, and the alarm clock processing method according to the embodiment of the present application. Additionally, the application processor 370 is coupled to the display unit 330.

Specifically, the application processor 370 may receive a power-on interrupt signal in two cases. In the first situation, when the mobile phone 300 is in the power-off state, the user presses the power button of the mobile phone 300 for a long time, and the baseband processor 321 receives the power-on instruction of the user pressing the computer button for a long time, and sends a power-on interrupt signal to the application processor 370, so as to power on the mobile phone.

In the second case, the user sets an alarm before the mobile phone 300 is powered off, and the mobile phone 300 saves the alarm time set by the user to an alarm register, which may be a part of the space in the memory 380. After the mobile phone 300 is powered off, the real-time clock chip 322 still continues to time, and when the alarm clock time set by the user is reached, the real-time clock chip 322 may send a power-on interrupt signal to the application processor 370 through the baseband processor, so as to power on the mobile phone.

For example, when saving the alarm clock time set by the user, the mobile phone 300 may save the alarm clock time obtained by adding the RTC chip time to the time difference between the time set by the user and the current time to an alarm clock register, where the RTC time is the time timed by the real-time clock chip 322. Meanwhile, the real-time clock chip 322 continues to count time, and the time counted by the real-time clock chip 322 increases in seconds. After the mobile phone 300 is powered off, a part of the power remains in operation while a part of the functions are still running, such as the real-time clock chip 322 continues to count time. When the time recorded by the real time clock chip 322 is equal to the time difference saved in the alarm clock register, the alarm clock time set by the user is indicated to arrive.

For example, when 21:00 evening at 3/2/2020, the user sets an alarm clock at 7:00 morning the next morning, i.e. an alarm clock at 7:00 morning at 3/2020. Assuming that the RTC chip is running for 15000s at this time, the cell phone 300 stores the time difference between the time (03-03-202007: 00:00) set by the user and the current time (03-02-202021: 00:00) and the alarm clock time obtained by adding 15000 to the alarm clock register. Meanwhile, the time clocked by the real time clock chip 322 continues to increase in seconds. When the mobile phone 300 is powered off at rest at night, the real-time clock chip 322 still keeps timing after being powered off, and when the time recorded by the real-time clock chip 322 is equal to the alarm clock time stored in the alarm clock register, the alarm clock time set by the user is indicated.

The real-time clock chip 322 detects that the alarm clock time set by the user arrives, and sends a power-on interrupt signal to the application processor 370 through the baseband processor 321, so as to power on the mobile phone.

In the two different cases, the baseband processor 321 sends a power-on interrupt signal to the application processor 370 through different pins. The application processor 370 may determine whether the received power-on interrupt signal is triggered by the real-time clock chip 322 or by the user pressing a power button for a long time based on the pin sending the power-on interrupt signal.

If the application processor 370 receives the power-on interrupt signal sent by the real-time clock chip 322, it starts LK (Little Kernel, small operating system) first, and performs peripheral initialization, low-power charging, picture display, indicator light prompt, etc. in the LK stage, so as to prepare for loading img for normal power-on, and low-power-on and alarm clock processing are also performed in the LK stage. The application processor 370 detects the voltage of the power module 390, compares the voltage of the power module 390 with the power-on voltage of the mobile phone, and turns off the alarm function if the voltage of the power module 390 is lower than the power-on voltage of the mobile phone. The starting voltage of the mobile phone can be measured and recorded in advance. Typically, the turn-on voltage of the handset is between (3.3V-3.6V). If the voltage of the power module 390 is lower than the power-on voltage of the mobile phone 300, the alarm clock function is turned off, so as to avoid the mobile phone from entering the cycle of repeated power-on and power-off to consume the electric energy of the power module, prevent the damage to the power module and the hardware resources of the mobile phone after the electric energy of the power module is completely exhausted, and shorten the charging time when the mobile phone is charged again.

Further, in some embodiments, the handset 300 may turn off the alarm clock function by disabling the power-on interrupt signaling function of the real-time clock chip 322. After disabling the power-on interrupt signal sending function of the real-time clock chip 322, the real-time clock chip 322 does not trigger the baseband processor 321 to send the power-on interrupt signal to the application processor 370 any more even when the alarm clock time set by the user is reached. Optionally, after disabling the power-on interrupt signal sending function of the real-time clock chip 322, the alarm clock time stored in the alarm clock register corresponding to the real-time clock chip may also be cleared.

If the voltage of the power module 390 is equal to or higher than the power-on voltage of the mobile phone 300, the operating system of the mobile phone 300 is started and the alarm clock process is started.

In an alternative embodiment, if the voltage of the power module 390 is equal to or higher than the boot voltage of the mobile phone 300, the operating system kernel is started through the LK system, the reason for the system boot is determined in the boot program uboot started by the LK, and if the boot is enabled by the real-time clock chip, the boot parameters are transmitted to the system kernel through the cmdlet command line in the uboot. For example, a start mode parameter android, mode, alarm, is passed to the system kernel. And then judging a starting mode in an init initial process, and if the starting mode is an alarm clock starting mode, acquiring an alarm clock starting parameter. The alarm clock starting parameters comprise a ringing mode, alarm clock ringing and the like. And after the system kernel is started, the system kernel starts an alarm clock process according to the alarm clock starting parameters and executes ringing operation.

In some embodiments, after the alarm clock function is turned off, the application processor 370 ignores the power-on interrupt signal and maintains the power-off state of the mobile phone, i.e. the application processor 370 no longer responds to the power-on interrupt signal and performs the corresponding power-on operation, so as to avoid unnecessary power consumption caused by power-off again due to too low voltage during the power-on process, and also reduce the consumption of hardware resources of the mobile phone.

In some embodiments, the application processor 370 receives the power-on interrupt signal from the real-time clock chip 322, detects the voltage of the power module 390, compares the voltage of the power module 390 with the power-on voltage of the mobile phone, and detects whether the power module 390 is in a charging state if the voltage of the power module 390 is lower than the power-on voltage of the mobile phone.

For example, for a mobile phone that is charged by connecting a charging line to a USB interface, whether the power module 390 is in a charging state can be determined by detecting whether the charging line is connected to the USB interface. For a mobile phone charged by other methods, such as a wireless charging method, a first voltage value of the power module 390 at a previous sampling time and a second voltage value of the power module at a later sampling time may be obtained, the first voltage value and the second voltage value are compared, and whether the power module 390 is in a charging state is determined according to the comparison result. If the second voltage value is greater than the first voltage value, it indicates that the power module 390 is in a charging state; otherwise, if the second voltage value is less than or equal to the first voltage value, it indicates that the power module 390 is not in the charging state. The second detection method may be applied to a mobile phone that is charged by connecting a charging cable to a USB interface.

If the power module 390 is not in the charging state, the step of turning off the alarm clock function is executed to avoid the mobile phone 300 from entering the cycle of repeatedly turning on and off the mobile phone to consume the power of the power module.

Considering that when the power module is in a charging state, the voltage of the power module can be recovered to the starting voltage of the mobile phone within a short time, and at this time, if the mobile phone is started and the alarm clock is started, although the time is later than the time of the alarm clock set by the user, the time reminding function can still be achieved. Therefore, in one possible embodiment, if the power module 390 is in the charging state, the voltage of the power module is detected again after the preset time period. Wherein the preset time period can be any time period within 5 minutes. If the voltage of the power module 390 is equal to or higher than the power-on voltage of the mobile phone 300, the operating system of the mobile phone 300 is started and the alarm clock process is started, so that the alarm clock rings normally to play a time reminding role. If the voltage of the power module 390 is still lower than the power-on voltage of the handset 300, the alarm clock function is turned off.

In an alternative embodiment, the baseband processor may be integrated into the application processor 370, that is, the application processor 370 includes a CPU and the baseband processor, the CPU mainly processes an operating system, a user interface, an application program, and the like, and the baseband processor mainly processes wireless communication. That is, the baseband module 320 may not include the baseband processor 321, but only include the real-time clock chip 322 and other basic circuits. When the real-time clock chip 322 detects that the alarm clock time set by the user is reached, it sends a power-on interrupt signal to the application processor 370 to power on the mobile phone. The application processor 370 receives the power-on interrupt signal from the real-time clock chip 322 and detects the voltage of the power module 390. If the voltage of the power module 390 is equal to or higher than the power-on voltage of the mobile phone 300, the operating system of the mobile phone is started and the alarm clock process is started. If the voltage of the power module 390 is lower than the power-on voltage of the mobile phone 300, the alarm function is turned off.

Optionally, the mobile phone 300 may further include a bluetooth module for performing information interaction with other bluetooth devices having the bluetooth module through a bluetooth protocol. For example, the mobile phone 300 may establish a bluetooth connection with a wearable electronic device (e.g., a smart watch) having a bluetooth module through the bluetooth module, so as to perform data interaction.

The handset 300 may also include a camera for capturing still images or video. The number of the cameras can be one or more. The object generates an optical image through the lens and projects the optical image to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing elements convert the optical signals into electrical signals which are then passed to the application processor 370 for conversion into digital image signals.

The handset 300 may also include a peripheral interface, such as the USB interface described above, for connecting a charging cord or other peripheral. As shown in fig. 4, the mobile phone 300 may be connected to a charging line 400 through a USB interface 391.

Fig. 6 shows a schematic diagram of corresponding user interfaces when the alarm clock function is set by the mobile phone. In some embodiments, the user may open the corresponding application by touching the application icon on the desktop of the mobile phone, or may open the corresponding folder by touching the folder icon on the desktop of the mobile phone, and open the corresponding application in the folder. As shown in fig. 6, the user touches the "clock" application icon in the page a to open the clock application, and the interface of the clock application is shown in the page b and includes functional modules such as an alarm clock, a stopwatch, and a timer. The user touches the alarm clock function module in the page b, namely, the alarm clock setting page is entered, as shown in the page c, the user can select the alarm clock time in the page c, and after the user sets the alarm clock time according to the user's needs, the user clicks to complete the alarm clock setting operation.

For the above scenario, the alarm clock processing method provided in the embodiment of the present application is further described in detail below with reference to a flowchart.

Fig. 7 shows a flowchart of an alarm clock processing method provided in an embodiment of the present application, and as shown in fig. 7, the method includes the following steps:

step S701, when the electronic device is in the power-off state, receives a power-on interrupt signal sent by the real-time clock chip.

The starting-up interrupt signal is sent when the real-time clock chip monitors that the alarm clock time set by the user arrives. Specifically, if the user sets an alarm clock before the electronic device is turned off, the electronic device saves the alarm clock time set by the user to an alarm clock register. After the electronic equipment is shut down, the real-time clock chip still continues timing, and when the alarm clock time set by a user is reached, the real-time clock chip sends a starting interruption signal to the application processor so as to trigger the electronic equipment to start.

Step S702 detects a voltage of a power module of the electronic device.

After receiving a power-on interrupt signal sent by the real-time clock chip, the application processor can acquire the current voltage value of the power module through the power management module.

Step S703, judging whether the voltage of the power supply module is lower than the starting voltage of the electronic equipment; if yes, go to step S704, if no, go to step S706.

Illustratively, the power-on voltage of the electronic device may be recorded in advance, for example, the power-on voltage of the electronic device is 3.6V.

Step S704, turn off the alarm function.

If the voltage of the power supply module is lower than the starting voltage of the electronic equipment, the starting interruption signal sending function of the real-time clock chip can be forbidden to close the alarm clock function, the electronic equipment is prevented from entering the cycle of repeated starting and closing and consuming the electric energy of the power supply module, the power supply module and the hardware resources of the electronic equipment are prevented from being damaged after the electric energy of the power supply module is completely exhausted, and the charging time length during recharging is shortened. Optionally, after disabling the power-on interrupt signal sending function of the real-time clock chip, the alarm clock time stored in the alarm clock register corresponding to the real-time clock chip may also be cleared.

After the electronic device is charged and restarted, or when the user sets the alarm clock function next time, the starting interruption signal sending function of the real-time clock chip can be started again.

Step S705, ignoring the power-on interrupt signal and maintaining the power-off state of the electronic device.

The application processor does not respond to the power-on interrupt signal and executes corresponding power-on operation any more, so that unnecessary power consumption caused by power-off again due to too low voltage in the power-on process is avoided, and consumption of hardware resources of the electronic equipment can be reduced.

Step S706, start the operating system of the electronic device and start the alarm clock process.

It should be noted that the step S705 is an optional step, in some embodiments, the step S705 may not be executed, and in the process of starting the electronic device, the power module cannot provide sufficient voltage, and the electronic device will be shut down.

Fig. 8 is a flowchart illustrating another alarm clock processing method provided in the embodiment of the present application, and as shown in fig. 8, the method includes the following steps:

step S801 is to receive a power-on interrupt signal sent by the real-time clock chip when the electronic device is in a power-off state.

The starting-up interrupt signal is sent when the real-time clock chip monitors that the alarm clock time set by the user arrives.

Step S802, detecting a voltage of a power module of the electronic device.

Step S803, judge whether the voltage of the power module is lower than the starting voltage of the electronic device; if yes, step S804 is performed, and if no, step S809 is performed.

Step S804, detecting whether the power supply module is in a charging state; if yes, go to step S805; if not, executing step S808;

step S805, waiting for a preset duration, and detecting the voltage of the power module of the electronic device again.

Step 806, determining whether the voltage of the power module at the current moment is lower than the starting voltage of the electronic device; if yes, step S807 is executed, and if no, step S809 is executed.

Step S807, the alarm clock function is turned off.

Step S808, turning off the alarm clock function, ignoring the power-on interrupt signal, and maintaining the power-off state of the electronic device.

And step S809, starting an operating system of the electronic equipment and starting an alarm clock process.

In this embodiment, it is considered that when the power supply module is in the charging state, the voltage of the power supply module can be recovered to the power-on voltage of the mobile phone in a short time. Therefore, if the power module is in a charging state, the voltage of the power module is detected again after the preset time length is up. If the voltage of the power supply module is equal to or higher than the starting voltage of the electronic equipment, an operating system of the mobile phone is started and an alarm clock process is started, so that the alarm clock rings normally, and the time reminding function is achieved.
