Description

Shutdown method, electronic equipment, storage medium and chip

Technical Field

The present disclosure relates to the field of terminals, and more particularly, to a shutdown method and an electronic device in the field of terminals.

Background

The current electronic devices have the functions of startup and shutdown. In the shutdown process of an electronic device (for example, a mobile phone) based on an android system, the electronic device first shuts down the backlight, and then executes a subsequent shutdown process under the condition of a black screen.

However, in the shutdown process, shutdown jam (unable shutdown) may occur, resulting in poor user experience. For example, in a scenario where only power-off is performed, the electronic device consumes power until the power is 0, which eventually results in no power-on and poor user experience. For another example, in a scenario where the electronic device is restarted (the user starts to restart or restarts after the electronic device is automatically upgraded), the electronic device always turns off the screen, and the user does not start up for the electronic device by mistake, so that the user experience is poor.

Based on this, it is needed to provide a shutdown method to solve the problem that the electronic device cannot be shutdown for a long time due to shutdown jam of the electronic device, so as to improve the user experience.

Disclosure of Invention

The application provides a shutdown method and electronic equipment, which can solve the problem that the electronic equipment cannot be shut down for a long time due to shutdown blocking of the electronic equipment, and improve user experience.

In a first aspect, a shutdown method is provided, which is characterized in that the shutdown method is applied to a system including an application framework layer, a system library and a kernel layer, the application framework layer includes a watchdog module, and the kernel layer includes a shutdown monitoring module, and the method includes:

After the system library receives a shutdown instruction, stopping the operation of the watchdog module through the kernel layer;

after the watchdog module stops running, the shutdown monitoring module starts timing;

and after the timing of the shutdown monitoring module exceeds the preset time, if the shutdown is not completed, triggering the system to reset and restart by the shutdown monitoring module.

According to the electronic equipment provided by the embodiment of the application, the related shutdown monitoring module is operated in the kernel layer, and in the shutdown process, even if the process of the upper layer is killed, the shutdown monitoring module is still in operation, so that the shutdown process can be monitored for a long time; meanwhile, the watchdog module running in the system library is utilized, after the watchdog module is killed in the shutdown process, the watchdog module stops running and can trigger the shutdown monitoring module to start timing, and after the timing exceeds the preset time, the shutdown monitoring module triggers the system to reset and restart. Therefore, the shutdown monitoring module can monitor the shutdown process after the watchdog module stops running through the preset time, if the shutdown jamming condition occurs in the process, and the system is not shutdown after the preset time, the system is triggered to automatically reset and restart, the problem that the electronic equipment cannot be normally shutdown for a long time due to shutdown jamming can be effectively avoided, and the user experience is improved. In addition, the time for killing the watchdog module in the shutdown process is relatively forward, so that the shutdown monitoring module is more beneficial to monitoring the shutdown process for a longer time. It can be seen that, compared with the shutdown blocking problem that the prior art only can monitor the initialization (init) process, the embodiment of the application can monitor the shutdown blocking problem that appears in the shutdown process after the watchdog module stops running, and after the blocking problem appears, the device can reset in time and restart, thereby improving the user experience very well.

Optionally, the preset duration is a first duration; the method comprises the steps of,

In the prior art, a shutdown monitoring thread in a system library can directly skip detection of whether data restoration is performed, so that the data restoration process becomes a dead zone. In the shutdown method provided by the embodiment of the application, the shutdown monitoring module can detect whether the system performs data restoration, and when the system performs data restoration, the preset time length counted by the shutdown monitoring module corresponds to the first time length, so that after the time length exceeds the first time length, if the system does not finish shutdown, the shutdown monitoring module triggers the system to reset and restart, the scene of data restoration of the system can be effectively considered, and the user experience in the scene is improved.

Optionally, the method further comprises:

when the timing of the shutdown monitoring module is a second time length, the shutdown monitoring module detects whether the system performs data restoration, wherein the second time length is the time length of the timing of the shutdown monitoring module when the system does not perform data restoration, and the second time length is smaller than the first time length; the method comprises the steps of,

and under the condition that the shutdown monitoring module detects that the system performs data restoration, after the shutdown monitoring module counts the time exceeding the first time length, if the system does not complete shutdown, the shutdown monitoring module triggers system reset restart, including:

and under the condition that the shutdown monitoring module detects that the system performs data restoration, the shutdown monitoring module continues to count time, and after the count time exceeds the first time, if the system does not complete shutdown, the shutdown monitoring module triggers the system to reset and restart.

According to the shutdown method provided by the embodiment of the application, two preset durations are arranged in the system, namely, a first duration and a second duration, wherein the first duration is the duration counted by the shutdown monitoring module when the system performs data restoration, the second duration is the duration counted by the shutdown monitoring module when the system does not perform data restoration, the shutdown monitoring module can detect whether the system performs data restoration when the second duration is counted, and the shutdown monitoring module can continue to count until the count exceeds the first duration under the condition that the system performs data restoration is detected, and if the system does not finish shutdown, the shutdown monitoring module can trigger the system to reset and restart. Under the condition that the system performs data restoration, the event timed to the second time length is used as a trigger event for detecting whether the data restoration is performed or not, other time or time length is not required to be additionally set for triggering whether the data restoration is performed or not, the design of the system is effectively utilized, and the implementation process is convenient.

Optionally, the preset duration is a second duration; the method comprises the steps of,

and under the condition that the shutdown monitoring module detects that the system does not carry out data restoration, after the shutdown monitoring module counts the time exceeding the second time, if the system does not finish shutdown, the shutdown monitoring module triggers the system to reset and restart.

Optionally, after the system library receives the shutdown instruction, before stopping the operation of the watchdog module through the kernel layer, the method further includes:

the watchdog module periodically executes a watchdog feeding operation to trigger the shutdown monitoring module to execute a zero clearing operation on the zone bit; the method comprises the steps of,

after the watchdog module stops running, the shutdown monitoring module starts timing, and the shutdown monitoring module comprises:

and after the watchdog module stops running, the shutdown monitoring module counts time through the counting of the zone bit.

According to the shutdown method provided by the embodiment of the application, a flag bit is introduced into the kernel layer, the flag bit can be understood as a counter or a counter used for timing, and the product of the numerical value of the flag bit and the counted period duration is the timing duration of the shutdown monitoring module. The watchdog module is triggered to execute the zero clearing operation of the zone bit by using the watchdog feeding operation of the watchdog module, which means that the watchdog module is still in operation, and the watchdog module is not triggered to execute the zero clearing operation of the zone bit after no longer running, so that the shutdown monitoring module can periodically count on the zone bit to achieve the aim of timing monitoring, and the process is relatively simple and convenient to realize.

Optionally, the preset time period is longer than or equal to the time period of normal shutdown of the system.

Optionally, the preset duration is 30 minutes or 120 seconds.

The capacitive pressure sensor may be a capacitive pressure sensor comprising at least two parallel plates with conductive material. The capacitance between the electrodes changes when a force is applied to the pressure sensor 180A. The electronic device 100 determines the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic apparatus 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 may also calculate the location of the touch based on the detection signal of the pressure sensor 180A.

And executing an instruction for newly creating the short message when the touch operation with the touch operation intensity being greater than or equal to the first pressure threshold acts on the short message application icon.

It should be understood that the technical solution in the embodiment of the present application may be used in Android, IOS, hong meng, and other systems.

The embodiment of the application relates to a shutdown process, wherein the shutdown process can be a process of shutdown only, can be a shutdown process in a restarting process of electronic equipment, and can be a restarting process of active starting by a user, and can be a restarting process in an automatic upgrading process of the electronic equipment.

Fig. 3 is a schematic diagram of a shutdown procedure provided in an embodiment of the present application. When the electronic device is turned off, the user presses the power key, and the electronic device performs steps S310 to S350.

In S310, the electronic device turns off the backlight, and at this time, the electronic device is in a black screen state.

In S320, the initialization module in the system library executes the processes killing the upper layers (such as the application framework layer and the system library) through the kernel layer, so that each process stops running.

In S330, the electronic device performs scanning of data repair (fsck) during shutdown, i.e. checks whether the file in the electronic device is damaged, and if so, the initialization module may perform data repair. The duration of this process may be tens of minutes, more hours, as short as the number of files in the electronic device and the extent of damage.

Of course, if the file in the electronic device is not damaged or is damaged little, S330 may be skipped and S340 may be performed.

In S340, the electronic device performs kernel shutdown, after the initialization process is finished, the shutdown process of the kernel is invoked, after that, the shutdown enters a kernel stage, the kernel can complete unloading of some driving resources, and then the power supply system is invoked to perform power-down processing.

In S350, the electronic device performs an operation of powering down when power is off.

In the shutdown process, the shutdown jamming condition can occur, so that the user experience is poor. A mobile phone is taken as an example to describe different scenes.

For example, in a scene of only powering off, the mobile phone will turn off the backlight first, the user perceives that the mobile phone has been powered off, but if a status of power off blocking occurs in the power off process, the mobile phone will consume power until the electric quantity is 0, which finally results in no power on and poor user experience. In addition, the battery is charged slowly and is not charged in the early stage of the power consumption, the user perceives that the mobile phone is not started, the mobile phone is started after the mobile phone is fully charged, the problems of high power consumption and short standby time of the mobile phone can be brought to the user, and the user experience is poor.

For another example, in a scenario that the user performs a restarting operation on the mobile phone, the mobile phone still turns off the backlight first, but if the mobile phone is blocked by the shutdown, the mobile phone always turns off the black screen, so that the user perceives that the mobile phone is turned off, and the function experience is poor. And because the forced restarting key of the mobile phone is a combination key, part of users are unclear and can misuse the mobile phone not to start up, so that the reliability experience is very bad.

For another example, the mobile phone can automatically restart after automatically executing the upgrade, and if the situation of shutdown and locking occurs, the user can experience the experience of the two scenes under the condition of no upgrade perception.

Based on this, the embodiment of the application provides a shutdown method, in which a shutdown monitoring module is configured in a kernel layer, and a watchdog module of a system library is utilized, after a process on an upper layer is killed in a shutdown process, the watchdog module is stopped, after the watchdog module stops running, the shutdown monitoring module can be triggered to start timing, and after the timing exceeds a preset duration, the shutdown monitoring module triggers a system to reset and restart. Therefore, the shutdown monitoring module can monitor the shutdown process after the watchdog module stops running, if the shutdown blocking problem occurs in the shutdown process, the electronic equipment triggers the automatic system reset restart after the preset time length, the problem that the electronic equipment cannot be normally shutdown for a long time due to shutdown blocking can be effectively avoided, and the user experience is improved.

It should be understood that the above shutdown monitoring module triggers the automatic system reset and restart after the preset time period is executed under the condition that the electronic device is not shutdown yet, if the electronic device has completed shutdown within the preset time period, the electronic device can basically be considered to be in a dead-lock state, normal shutdown can be realized, and the automatic system reset and restart is not required naturally after the preset time period is exceeded.

Fig. 4 is an exemplary flowchart of a shutdown method 400 provided by an embodiment of the present application. The method 400 is performed by an electronic device, which may be the electronic device 100 shown in fig. 1.

The method 400 is applied to a system comprising an application framework layer, a system library and a kernel layer, wherein the application framework layer comprises a watchdog module, and the kernel layer comprises a shutdown monitoring module. The system may be an android system, for example. Illustratively, the system further comprises: an application program layer and a hardware abstraction layer. The descriptions of the various layers in the system may refer to the descriptions of fig. 2, and will not be repeated.

In S410, after receiving the shutdown instruction, the system library stops the operation of the watchdog module through the kernel layer.

The shutdown instruction is used for instructing the electronic device to execute Guan Jinliu to realize shutdown of the electronic device. Illustratively, the shutdown instruction includes internal information for indicating a type of shutdown, for example, a type of shutdown is restarted (reboot) or shutdown (shutdown). It should be understood that shutdown (shutdown) in the shutdown instruction indicates an event in which only shutdown is performed.

When the system is powered off, in the implementation, the user presses the power key, the application program layer detects the operation of pressing the power key by the user, and the power-off broadcast is sent to the application frame layer, wherein the power-off broadcast comprises the type of power-off, and after the application frame layer receives the power-off broadcast, the power-off instruction is sent to the system library. And after the system library receives the shutdown instruction, notifying the kernel layer to execute the operation of killing the upper-layer process or thread, including killing the watchdog module, so as to stop the operation of the watchdog module. It should be appreciated that the watchdog module may be a process or thread capable of running at the application framework layer.

The watchdog module is used for periodically executing the feeding operation when operating normally. After the watchdog module stops running, the watchdog module stops executing the feeding operation.

Illustratively, in an implementation, the kernel layer creates a device node (e.g., dev/RT monitor) within the application framework layer that can be accessed by the application framework layer for communication with upper layers to monitor whether the watchdog module is operating properly. While the watchdog module is running, the watchdog module will write marks of the machine monitoring module in the device node periodically (e.g. every 30 seconds), and this process can be understood as the watchdog operation performed by the watchdog module. On the contrary, when the watchdog module stops running, the watchdog module does not execute the feeding operation and can trigger the shutdown monitoring module of the kernel layer to time.

In S420, after the watchdog module stops running, the shutdown monitoring module starts timing.

After the watchdog module stops running, the watchdog module does not execute the feeding operation, namely, the node of the machine closing monitoring module is not written into the equipment node any more, and the machine closing monitoring module can be triggered to start timing so as to monitor the subsequent machine closing process.

In the embodiment of the present application, a flag bit (falg) is introduced in the kernel layer, and the flag bit can be understood as a counter or counter for timing. The product of the number of the flag bit and the counted period duration is the duration of the shutdown monitoring module timing.

In some embodiments, when the watchdog module operates normally, the watchdog module periodically performs a watchdog feeding operation to trigger the shutdown monitoring module of the kernel layer to perform a zero clearing operation on the flag bit. Because the shutdown monitoring module executes the zero clearing operation on the flag bit, the value recorded by the flag bit is 0.

And otherwise, after the watchdog module stops running, the watchdog module stops executing the feeding operation so as to trigger the shutdown monitoring module to time through the zone bit. Because the shutdown monitoring module does not execute the zero clearing operation on the flag bit, the shutdown monitoring module is triggered to count through the flag bit so as to monitor the shutdown process.

In an implementation, when the watchdog module is running, the watchdog module writes the node of the shutdown monitoring module into the device node periodically (for example, every 30 seconds), and since the device node is created by the kernel layer, the operation that the device node writes the node of the shutdown monitoring module triggers the shutdown monitoring module of the kernel layer to perform a zero clearing action on the flag bit. When the watchdog module stops running, the watchdog module does not execute the feeding operation, namely, the node of the machine closing monitoring module is not written into the equipment node any more, and the shutdown monitoring module is not triggered to execute the zero clearing operation on the zone bit, so that the shutdown monitoring module does not detect the operation that the watchdog module writes the node of the machine closing monitoring module into the equipment node within a specific time (the next period of the last period), and then clocks through the mark bit.

For example, taking the period of 30 seconds as an example, the shutdown monitoring module performs a zero clearing operation in the last 30 seconds, the watchdog module is killed, the operation is stopped, the dog feeding operation is not performed any more in the current 30 seconds, the shutdown monitoring module does not detect the operation that the watchdog module writes the node of the shutdown monitoring module in the equipment node in the current 30 seconds, then after the current 30 seconds are overtime, the shutdown monitoring module starts timing, the value 1 is recorded on the flag bit, after the next 30 seconds are overtime, the value on the flag bit is increased by 1 (changed into 2), and the value on the flag bit is increased by 1 in the next 30 seconds, and so on every time the period is longer than one period.

It should be noted that, in the mode that the shutdown control module counts and counts through the flag bit, the shutdown control module periodically performs the accumulation of the values on the flag bit, and the period duration of this process may be the same as or different from the period duration of the watchdog module periodically performing the watchdog feeding operation. For example, in the example of 30s period duration described above, the period durations of the two processes are the same. It can be appreciated that in the embodiment of the two processes with the same period duration, the complexity of the scheme can be reduced, and the implementation is convenient.

In S430, after the shutdown monitoring module counts more than the preset time, if the system does not complete shutdown, the shutdown monitoring module triggers a reset restart of the system.

The preset time length is the time length preset by the system, the preset time length takes the time length of normal shutdown of the electronic equipment as a reference, and the preset time length represents the time length of normal shutdown of the electronic equipment under the condition that data restoration is not carried out. It should be understood that the time period of normal shutdown of the electronic device described herein refers to the time period of shutdown when the electronic device does not have a stuck state.

In an example, the preset time period is greater than or equal to a time period during which the electronic device is normally powered off.

For example, the duration of a normal shutdown of the electronic device may be 100 seconds, 110 seconds, 120 seconds. For example, the preset duration may be 120 seconds, 130 seconds, 140 seconds, or the like.

If the time required by the electronic device for data restoration is considered, the preset time can be set longer. Because the time length for repairing the data is related to the number of files and the damage degree in the electronic equipment, the time length is tens of minutes and more than a few hours, and the user experience is affected when the electronic equipment is not started for a long time, the preset time length is not too long. For example, the preset time period may be 20 minutes, 25 minutes, 30 minutes, or the like.

It should be noted that, if the preset duration is exceeded, the data repair process is not completed yet, and when the system is triggered to reset and restart, the data repair is interrupted, but the files in the electronic device are not damaged continuously, and the system can repair damaged files continuously when the system is started next time.

In other examples, since the shutdown monitoring module begins to time after the watchdog module stops running, the preset duration may be greater than or equal to a first duration that is a difference between a duration of normal shutdown of the electronic device and a second duration that is a duration between a time when the electronic device starts shutdown and a time when the watchdog module stops running.

In an exemplary implementation, when the shutdown monitoring module counts through the flag bit, if the value of the flag bit reaches the threshold value, the shutdown monitoring module triggers the system to reset and restart. This threshold value is available by the quotient of the preset duration and the counted period duration. For example, if the preset duration is 120 seconds, and the counted period duration is 30 seconds, the threshold is 4, and when the value of the flag bit is increased to 4, the threshold is reached, so that the system reset restart is triggered.

In the prior art, a shutdown method is proposed, a shutdown monitoring thread is started in a system library to monitor the blocking condition of the shutdown process, and if the blocking condition of the shutdown occurs within a monitoring period, an electronic device (such as a mobile phone) can automatically reset and restart the system within 3 minutes. Therefore, the electronic equipment can not be in a shutdown and locking state all the time, and the user experience can be improved. However, the shutdown monitoring thread is only effective in the initialization (init) process (step S320 in fig. 3), that is, only shutdown blocking of the initialization process can be monitored, and shutdown blocking of other processes (steps S330 to S350 in fig. 3) cannot be monitored. If the shutdown blocking occurs in other processes, the problem that the screen is blocked and the user perceives that the machine is not started still occurs, and the user experience is poor. The reason is that the shutdown monitoring thread runs in the system library, and when executing step S320, the process of the upper layer (the system library and the application framework layer) is killed, including the shutdown monitoring thread, so that the shutdown monitoring thread is designed to monitor only the process of init processing shutdown, and the process of turning to the shutdown process of the kernel and the process of performing data repair subsequently cannot be monitored.

In the application, because the shutdown monitoring module runs in the kernel layer, even if the process on the upper layer is killed, the shutdown monitoring module is still running, so that the shutdown process can be monitored for a long time; meanwhile, the watchdog module is utilized to run, after the upper layer process is killed in the shutdown process, the watchdog module is stopped, the shutdown monitoring module can be triggered to start timing, and after the timing exceeds the preset duration, the shutdown monitoring module can trigger the system to reset and restart. Therefore, the shutdown monitoring module can monitor the shutdown process after the watchdog module stops running through the preset time, if the shutdown jamming condition occurs in the process, and the electronic equipment is not shutdown after the preset time, the system is triggered to automatically reset and restart, the problem that the electronic equipment cannot be normally shutdown for a long time due to shutdown jamming can be effectively avoided, and the user experience is improved. In addition, the time for killing the watchdog module in the shutdown process is relatively forward, so that the shutdown monitoring module is more beneficial to monitoring the shutdown process for a longer time. It can be seen that, compared with the shutdown blocking problem that the prior art only can monitor the initialization (init) process, the embodiment of the application can monitor the shutdown blocking problem that appears in the shutdown process after the watchdog module stops running, and after the blocking problem appears, the device can reset in time and restart, thereby improving the user experience very well.

For example, taking fig. 3 as an example, the time t1 is the time when the watchdog module is killed and stops running, and the transmission delay between the layers is ignored, it can be understood that, as long as the preset duration is set appropriately, the shutdown monitoring module can monitor the whole shutdown process after the watchdog module stops running, and the monitored duration can be greater than or equal to the time 1.

As described above, if the file in the electronic device is damaged, the system will perform data repair. In order to simultaneously consider the situation that the system performs data restoration and does not perform data restoration, so that the problem of shutdown blocking can be better solved under different situations, two preset time periods, namely a first time period and a second time period, can be arranged in the system, wherein the first time period is used for a scene of performing data restoration on the system, the second time period is used for a scene of not performing data restoration on the system, and the shutdown monitoring module is used for judging whether the system performs data restoration or not.

In some embodiments, when the shutdown monitoring module detects that the system performs data repair, after the shutdown monitoring module counts more than the first time period, if the system does not complete shutdown, the shutdown monitoring module triggers the reset restart of the system. The preset time length is a first time length.

Because the time length for repairing the data is related to the number of files and the damage degree in the electronic equipment, the time length is tens of minutes, and more than a few hours, the user experience is affected when the electronic equipment is not started for a long time, and therefore the first time length is not too long. Illustratively, the first duration is 30 minutes.

In other embodiments, when the shutdown monitoring module detects that the system does not perform data repair, the shutdown monitoring module counts the time exceeding the second time period, and if the system does not complete shutdown, the shutdown monitoring module triggers the reset restart of the system. The preset duration is the second duration. Illustratively, the second duration is 120 seconds.

The embodiment of the application can detect whether the system performs data recovery in the following way.

In an exemplary implementation, a new flag bit (different from the one used for timing above) may be introduced in the kernel layer, with different contents of the flag bit representing different states. One content of the flag bit (for example, the flag bit has a value of 0) is used to indicate a state that the system performs data repair, and the other content of the flag bit (for example, the flag bit has a value of 1) is used to indicate a state that the system does not perform data repair, for example, the default state of the flag bit is that the system does not perform data repair. If the initialization module performs data recovery, the initialization module writes a node in the equipment node, and can trigger the kernel layer to modify a default marking bit into a state that the system performs data recovery, so that the shutdown monitoring module can detect that the system performs data recovery. If the initialization module does not perform data recovery, the initialization module does not write nodes in the equipment nodes, and the marking bit keeps a default state, so that the shutdown monitoring module can detect that the system does not perform data recovery. The device node may be a device node of the watchdog module writing node described above, or may be a new device node, which is not limited herein.

In the prior art, the shutdown monitoring thread can directly skip the detection of whether to carry out data restoration, so that the data restoration process becomes a dead zone. In the shutdown method provided by the embodiment of the application, the shutdown monitoring module can detect whether the system performs data restoration, and when the system performs data restoration, the preset time length counted by the shutdown monitoring module corresponds to the first time length, so that after the time length exceeds the first time length, if the system does not finish shutdown, the shutdown monitoring module triggers the system to reset and restart, the scene of data restoration of the system can be effectively considered, and the user experience in the scene is improved.

It should be understood that the above-described process of setting two preset durations and determining whether the system performs data restoration is merely exemplary, and should not be construed as limiting the embodiments of the present application.

In other embodiments, for example, only one time length may be set in the system, where the time length is the preset time length, and the shutdown monitoring module does not need to determine whether the system performs data restoration, and triggers a reset restart of the system if the time exceeds the preset time length. Of course, if the preset duration is set smaller, the embodiment may not consider the situation that the system performs data restoration, however, the influence on user experience is not very large, and data restoration in the next power-on process may also be performed.

In this embodiment of the present application, the shutdown monitoring module may detect whether the system performs data recovery at any time before the second time or during the second time, which is not limited in the embodiment of the present application.

In some embodiments, when the shutdown monitoring module counts a second time period, the shutdown monitoring module detects whether the system performs data repair, where the second time period is a time period corresponding to when the system does not perform data repair;

when the shutdown monitoring module detects that the system performs data restoration, the shutdown monitoring module continues to count time, and after the count time exceeds a first duration, if the system does not complete shutdown, the shutdown monitoring module triggers the reset restart of the system;

and under the condition that the shutdown monitoring module detects that the system library does not perform data recovery, if the system does not complete shutdown, the shutdown monitoring module triggers the system to reset and restart.

That is, the second time length corresponding to the data restoration is not used as a judging node, and when the shutdown monitoring module is timed to be the second time length, whether the system performs the data restoration is detected; under the condition that the system is detected to carry out data restoration, the shutdown monitoring module can continue to count time, and after the accumulated count time exceeds a first time length, if the system is not completely shutdown, the system is triggered to reset and restart; and under the condition that the system library is detected to be not subjected to data recovery, if the system is not completely shut down, directly triggering the system to reset and restart.

Taking the shutdown monitoring module to count by the flag bit for example, assume that the second duration is 120 seconds, the first duration is 30 minutes (1800 seconds), and the counted period duration is 30 seconds, then the threshold value corresponding to the second duration is 4, and the threshold value corresponding to the first duration is 60. When the number of the zone bit is increased to 4, the shutdown monitoring module detects whether the system performs data restoration, and when the system is detected to perform data restoration, the shutdown monitoring module continues to accumulate the number on the zone bit, and when the number of the zone bit is increased to 60, if the system is still not closed, the system is triggered to reset and restart; and under the condition that the system library is detected to be not subjected to data recovery, if the system is not completely shut down, directly triggering the system to reset and restart.

In S510, after receiving the shutdown instruction, the system library stops the operation of the watchdog module through the kernel layer.

In S520, after the watchdog module stops running, the shutdown monitoring module starts timing.

In S530, the shutdown monitoring module detects whether the timer is a second duration.

If the timing does not reach the second time length, continuing to detect the time length of the timing until the timing is the second time length; if the second time period is counted, S540 is performed.

In S540, if the shutdown monitoring module counts the second duration, the shutdown monitoring module detects whether the system performs data repair.

If the shutdown monitoring module detects that the system performs data restoration, S550 is executed; if the shutdown monitoring module detects that the system does not perform data repair, S560 is executed.

In S550, if the shutdown monitoring module detects that the system performs data repair, the shutdown monitoring module continues to count, and after the count exceeds the first time, if the system does not complete shutdown, the shutdown monitoring module triggers the reset restart of the system.

In S560, if the shutdown monitoring module detects that the system library does not perform data recovery, the shutdown monitoring module triggers a reset restart of the system if the system does not complete shutdown.
