Description

Screen freezing monitoring method, electronic equipment and computer readable storage medium

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a frozen screen monitoring method, an electronic device, and a computer-readable storage medium.

Background

The system of the electronic device may be crashed due to abnormal operation of some key processes, so that the phenomena of screen blacking, freezing of an interface of the device and incapability of effective operation, namely screen freezing and the like, are caused, for example, the phenomena of screen blacking are caused in the common system starting or operating process, and the phenomena of screen freezing and the like are caused in the system shutdown process so that the electronic device cannot be normally shut down.

Since the use of the system is affected after the system crashes, and the user experience is reduced, the occurrence of the system crash in the system operation process becomes a problem which needs to be solved urgently at present.

Disclosure of Invention

The application provides a frozen screen monitoring method, electronic equipment and a computer readable storage medium, and solves the problem of system breakdown in the system operation process in the prior art.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, a method for monitoring frozen screen is provided, which is applied to an electronic device, and includes:

starting a screen freezing monitoring process;

after receiving an enabling signal sent by a system service process, the screen freezing monitoring process does not monitor inter-process communication between the system service process and the screen freezing monitoring process within a first time period, or determines that the electronic equipment cannot end the process in a shutdown process, and triggers a system to restart, wherein the inter-process communication is used for indicating that the system service process normally operates, the first time period is longer than a second time period, and the second time period is a time interval of the inter-process communication between the system service process and the screen freezing monitoring process.

Therefore, when the screen freezing monitoring process monitors that the system service process is abnormally operated or the electronic equipment cannot be normally shut down, the screen freezing monitoring process triggers the system to restart in order to avoid the phenomena of screen blacking and the like caused by system crash, and therefore the problem of system crash in the system operation process is solved.

As an example of the present application, after receiving an enable signal sent by a system service process, the screen freezing monitoring process does not monitor inter-process communication between the system service process and the screen freezing monitoring process for a first time period, including:

after receiving an enabling signal sent by the system service process, the screen freezing monitoring process counts every third time length from a first value, wherein the counting comprises count-down or count-up;

in the counting process of the frozen screen monitoring process, counting is started from the first numerical value again every time the inter-process communication between the system service process and the frozen screen monitoring process is monitored;

and the screen freezing monitoring process detects that the count value reaches a second value, determines that inter-process communication between the system service process and the screen freezing monitoring process is not monitored in the first time length, and the first value, the second value and the third time length are used for determining the first time length.

Therefore, the frozen screen monitoring process determines whether the heartbeat packet sent by the system service process is not monitored in the first time length in a counting mode, so that whether the system service process runs normally is determined, the running state of the system service process is monitored, the system is conveniently triggered to restart under the condition that the system service process runs abnormally, and the phenomenon that the system is blocked due to system crash is avoided.

As an example of the present application, the counting includes a countdown, and after the freeze screen monitoring process receives an enable signal sent by a system service process, the method further includes:

the frozen screen monitoring process receives a numerical value modification instruction, updates the first numerical value to a third numerical value, wherein the numerical value modification instruction carries the third numerical value, the third numerical value is larger than the first numerical value, and the numerical value modification instruction is sent by the system service process under the condition that the system service running in the system service process is detected to be abnormal.

Therefore, when the system service operation in the system service process is detected to be abnormal, the system service process indicates the screen freezing monitoring process to adjust the first value so as to increase the first time length, and therefore the system is prevented from being restarted under the condition that the watchdog monitoring mechanism can recover the abnormity of the system service.

As an example of the present application, the method further comprises:

and the frozen screen monitoring process receives a numerical value resetting instruction, and renews the third numerical value to the first numerical value, wherein the numerical value resetting instruction is sent by the system service process under the condition that the system service is detected to be recovered to be normal.

Therefore, after the system service process monitors that the system service is recovered to be normal, the system service process indicates the screen freezing monitoring process to modify the first numerical value back to the original numerical value so as to recover the monitoring time of the screen freezing monitoring process.

As an example of the present application, after the screen freeze monitoring process does not monitor the inter-process communication between the system service process and the screen freeze monitoring process within the first duration, the method further includes:

and grabbing the stack information and storing the stack information. Therefore, the stack information can be uploaded to the data platform after the subsequent system is restarted, and fault analysis can be carried out based on the stored stack information.

As an example of the present application, after receiving an enable signal sent by a system service process, the screen freezing monitoring process does not monitor inter-process communication between the system service process and the screen freezing monitoring process for a first time period, including:

after receiving an enabling signal sent by the system service process, the frozen screen monitoring process starts timing;

in the process of timing, the frozen screen monitoring process restarts timing every time the inter-process communication between the system service process and the frozen screen monitoring process is monitored;

and the screen freezing monitoring process detects that the timing time reaches the first time, and determines that the inter-process communication between the system service process and the screen freezing monitoring process is not monitored in the first time.

Therefore, the frozen screen monitoring process determines whether the heartbeat packet sent by the system service process is not monitored in the first time length in a timing mode, so that whether the system service process runs normally is determined, the running state of the system service process is monitored, the system is conveniently triggered to restart under the condition that the system service process runs abnormally, and the phenomenon that the system is blocked due to system crash is avoided.

As an example of the present application, after receiving an enable signal sent by a system service process, the determining that the electronic device cannot end the process in the shutdown process by the freeze screen monitoring process includes:

after receiving an enabling signal sent by the system service process, the screen freezing monitoring process counts every third time length from a first value, wherein the counting comprises count-down or count-up;

in the counting process of the frozen screen monitoring process, counting is started from the first numerical value again every time the inter-process communication between the system service process and the frozen screen monitoring process is monitored;

and under the condition that the count value does not reach the second numerical value, the frozen screen monitoring process receives a shutdown notification, and if the system service process is detected to be finished and a process finishing instruction for finishing the frozen screen monitoring process is not received within a fourth time, the electronic equipment is determined to be incapable of finishing the process in the shutdown process.

That is, the freeze screen monitoring process performs the counting operation after receiving the enable signal sent by the system service process. In the counting process, if the counting value does not reach the second value and the shutdown notification is received, the shutdown operation is executed currently, and at this time, the screen freezing monitoring process can inquire whether the system service process is finished or not. Under the condition that the system service process is detected to be finished, if a process finishing instruction for finishing the screen freezing monitoring process is not received within the fourth time length, the system shutdown is blocked, and the electronic equipment can be determined to be incapable of finishing the process in the shutdown process.

As an example of the present application, the case that the process cannot be ended in the shutdown process of the electronic device includes: when the system service process is finished, the system service process is not found in a process running list, or the system service process is not finished in a fifth time length after an end instruction for finishing the system service process is sent, wherein the process running list comprises processes in a running state in a system.

As an example of the present application, the end timing of the freeze screen monitoring process is located after the end timing of the system service process.

Therefore, whether the system service process is normally finished or not can be detected in the process of shutting down the electronic equipment by the screen freezing monitoring process.

As an example of the present application, the freeze screen monitoring process is arranged at an end position in a target process list in the system, where the target process list is used to record an ending sequence of processes to be ended.

Therefore, the screen freezing monitoring process is arranged at the tail position in the target process list, so that more processes which cannot be finished can be monitored in the process of shutdown of the electronic equipment.

As an example of the application, the first duration is indicated by the system service process for the freeze screen monitoring process, or the first duration is preset.

In one embodiment, the first time length is indicated by the system service process, so that the frozen screen monitoring process can be monitored within the effective time length, and the monitoring accuracy is ensured.

As an example of the present application, the second duration is a duration during which all system services in the system service process are monitored in a traversal mode once, or the second duration is preset.

In an embodiment, the second duration is a duration of monitoring all system services in the system service process in a traversal manner, for example, after the watchdog monitoring mechanism monitors each system service in the system service process once, a heartbeat packet is sent to the freeze screen monitoring mechanism once under the condition that it is determined that the system service process is operating normally. Therefore, the inter-process communication with the frozen screen monitoring process is carried out under the condition that the system service is normal, so that the reliability of monitoring the running condition of the system service process is ensured.

For example, when a photo is taken, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in camera 193.

The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into image signal in standard RGB, YUV and other formats. In some embodiments, the electronic device 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

The software system of the electronic device 100 may employ a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present invention uses an Android system with a layered architecture as an example to exemplarily illustrate a software structure of the electronic device 100.

Fig. 2 is a block diagram of a software structure of the electronic device 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, which are an application layer, an application framework layer, a middleware layer, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in fig. 2, the application framework layer includes a system service module, a media framework, and a display framework.

The system service module runs in a system service (system server) process, the system service process is a core process in the electronic device, and the system service process can create a plurality of system services known by an application layer after being started, such as system services including but not limited to power management services and screen brightness management services.

In one example, the system services module may include a window manager, a resource manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The middleware layer includes a system library. In some embodiments, the middleware layer is also referred to as a native framework layer.

In the embodiment of the application, the middleware layer comprises a frozen screen monitoring module, and the frozen screen monitoring module runs in a frozen screen monitoring process. In one example, the frozen screen monitoring process is used for monitoring the system service process so as to trigger the system to restart when the system service process is in a zombie state, thereby avoiding system crash and further avoiding the phenomena of screen freezing, screen blacking, no response and the like. Wherein, no response means that the screen is not lightened when the power key is clicked, and no response is caused when the screen is clicked.

The system library may include a plurality of functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), and the like.

The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, and the like.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The following describes exemplary workflow of the software and hardware of the electronic device 100 in connection with capturing a photo scene.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 193.

After the execution main body related to the embodiment of the present application is described, a method for monitoring freeze-shielding provided by the embodiment of the present application is described below with reference to the accompanying drawings.

Referring to fig. 3, fig. 3 is a schematic flow chart of a freeze screen monitoring method provided in an embodiment of the present application, which may be applied to the electronic device, by way of example and not limitation, and the method may include the following steps:

step 301: and starting a screen freezing monitoring process.

In the embodiment of the application, the screen freezing monitoring process is used for monitoring whether a system crash event occurs in the electronic device and correspondingly processing the system crash event when the system crash event is monitored, so as to avoid system jamming.

In one embodiment, the electronic device initiates a freeze screen monitoring process through an initialization (init) process. The init process is a user-level process started by a kernel, and is also a first started process of the electronic equipment in the starting process. After the init process is started, other processes in the system can be started by the init process. For example, referring to fig. 4, in the embodiment of the present application, the electronic device starts a screen freeze monitoring process through an init process, and in addition, the init process starts an incubation (zygate) process to start a system service process through the zygate process.

As an example of the present application, the freeze screen monitoring process is initiated before the system service process. Of course, in another embodiment, the freeze screen monitoring process may also be initiated in parallel with the system services process.

Step 302: after the freeze screen monitoring process receives an enabling signal sent by the system service process, the inter-process communication between the system service process and the freeze screen monitoring process is not monitored within a first time period, and the system is triggered to restart.

The inter-process communication is used for indicating that the system service process runs normally. The first duration is longer than the second duration, and the second duration is a time interval of interprocess communication between the system service process and the screen freezing monitoring process.

The inter-process communication can be realized by calling a function, and the commonly used inter-process communication comprises sending a heartbeat packet and sharing storage. In this embodiment, an example of sending a heartbeat packet to indicate that a system service process is operating normally is taken as an example for explanation.

That is, after the system service process is started, an enable signal is sent to the screen freezing monitoring process. And the system service process sends heartbeat packets to the frozen screen monitoring process every second time interval under the condition of normal operation so as to carry out interprocess communication with the frozen screen monitoring process.

By way of example and not limitation, referring to fig. 4, a system service process initiates a service monitoring mechanism in the system service process, where the service monitoring mechanism is used to manage system services running in the system service process. Illustratively, the service monitoring mechanism is a watchdog monitoring mechanism. The watchdog monitoring mechanism can be used for monitoring system services running in a system service process and capturing stack information under the condition that the system services are monitored to be abnormal. In addition, the watchdog monitoring mechanism restarts the system service if it monitors that the system service is abnormal and is not automatically recovered within a specified time (e.g., 60 s).

In some cases, the system service process may not run due to an exception, so that the watchdog monitoring mechanism fails to monitor the running condition of the service, and the service cannot be restarted, thereby causing a system crash and affecting user experience. In the embodiment of the application, after the watchdog monitoring mechanism in the system service process is initialized successfully, the watchdog monitoring mechanism sends an enabling signal to the screen freezing monitoring process. In addition, a watchdog monitoring mechanism in the system service process monitors the running state of the system service running in the system service process, and sends a heartbeat packet to the screen freezing monitoring process every second time period under the condition that the system service process is determined to run normally.

In an embodiment, the second duration is a duration of monitoring all system services in the system service process in a traversal manner, for example, after the watchdog monitoring mechanism monitors each system service in the system service process once, a heartbeat packet is sent to the freeze screen monitoring mechanism once under the condition that it is determined that the system service process is operating normally.

In another embodiment, the second time period is preset, and illustratively, the second time period is 30 seconds.

And after receiving the enabling signal, the frozen screen monitoring process starts to execute a monitoring function so as to monitor whether the system service process normally operates or not, or monitor whether a watchdog monitoring mechanism is invalid or not. As an example of the present application, if the freeze screen monitoring mechanism does not receive a heartbeat packet sent by the system service process within the first duration, it indicates that the system service process cannot operate normally, and at this time, it may be determined that the system service process is abnormal, and in order to avoid system jamming, the freeze screen monitoring process triggers a system restart, for example, the freeze screen monitoring process calls a bottom power-down related interface to power down and shut down the system, and then calls a bottom power-up interface at regular time, so as to restart the system.

In one embodiment, the first duration is indicated by the system service process for the freeze screen monitoring process. Illustratively, the system service process may indicate the first duration to the freeze screen monitoring process by an enable signal; or, the system service process may also separately indicate the first duration to the frozen screen monitoring process, for example, the system service process may indicate the first duration to the frozen screen monitoring process after sending the enable signal to the frozen screen monitoring process.

As a possible implementation manner, the indicating, by the system service process, the first duration for the frozen screen monitoring process includes: and the system service process directly determines the first time length and sends the determined first time length to the screen freezing monitoring process. For example, the system service process determines that the first duration is 150 seconds and sends 150 seconds to the freeze monitor process.

As another possible implementation manner, the indicating, by the system service process, the first duration for the frozen screen monitoring process includes: and the system service process sends a numerical value for determining the first time length to the frozen screen monitoring process, so that the frozen screen monitoring process determines the first time length according to a preset algorithm according to the numerical value sent by the system service process. For example, the value sent by the system service process to the freeze screen monitoring process is 5, and the freeze screen monitoring process determines the first time length according to a preset algorithm according to 5. The preset algorithm can be set according to actual requirements. In another embodiment, the first duration may also be preset. Such as a first duration of 150 seconds.

In a possible implementation manner, if the freeze screen monitoring process does not monitor the heartbeat packet sent by the system service process within the first time period, the stack information can be captured and stored in addition to triggering the system to restart, so that the stack information can be uploaded to a data platform after a subsequent system is restarted, and fault analysis is performed based on the stored stack information.

In the embodiment of the application, a freeze screen monitoring process is started. After the frozen screen monitoring process receives an enabling signal sent by a system service process, if a heartbeat packet sent by the system service process is received within a first time period, the system service process is determined to be abnormal in operation, and at the moment, the frozen screen monitoring process triggers the system to restart in order to avoid the phenomena of screen blacking and the like caused by system crash, so that the problem that the system crash is caused by the fact that the system service process cannot normally operate is solved.

On the basis of the embodiment shown in fig. 3, please refer to fig. 5, where fig. 5 is a schematic flow chart of a freeze screen monitoring method according to another exemplary embodiment, by way of example and not limitation, the method may be applied to the electronic device, and the method may include the following:

step 501: and starting a screen freezing monitoring process.

The specific implementation of this method can be seen instep 301 in the embodiment shown in fig. 3, and details are not repeated here.

Step 502: and counting every third time length from the first value after the freeze screen monitoring process receives the enabling signal sent by the system service process.

The third time period may be set according to actual requirements, and is exemplarily the same as the second time period, for example, the third time period may be 30 seconds.

Wherein counting comprises incrementing or decrementing. In addition, the increment value or the decrement value can be set according to actual requirements, and exemplarily, the increment value or the decrement value can be 1, that is, the first value is increased by 1 or decreased by 1 each time.

As an example of the present application, the first value may be a value sent by the system service process to the freeze monitor process, for example, the system service process may carry the first value by an enable signal, and the first value is used for determining the first duration. As another example of the present application, the first numerical value may also be set in advance.

Illustratively, the first value is 5, the third time period is 30 seconds, and the count is a countdown. After the system service process sends the enabling signal to the screen freezing monitoring process, the screen freezing monitoring process starts from 5, and subtracts 1 from the first numerical value every 30 seconds, that is, after 30 seconds, the first numerical value is updated to 4, after 60 seconds, the first numerical value is updated to 3, and so on.

Step 503: and in the counting process, the screen freezing monitoring process monitors whether the interprocess communication between the system service process and the screen freezing monitoring process is monitored.

And in the counting process of the frozen screen monitoring process, counting is started from the first numerical value again every time the interprocess communication between the system service process and the frozen screen monitoring process is monitored.

As an implementation manner, in the counting process, each time a heartbeat packet sent by the system service process is received, it indicates that the system service process is currently in a normal running state, that is, the system service process is not abnormal. In this case, the freeze monitoring process starts counting again from the first value, i.e., starts counting up again from the first value, and counts down or counts up every third time period. For example, taking the first value as an example, the freeze screen monitoring process starts from 5 again and counts down every 30 seconds every time a heartbeat packet sent by the system service process is received.

Step 504: and if the screen freezing monitoring process detects that the count value reaches a second value, determining that inter-process communication between the system service process and the screen freezing monitoring process is not monitored in the first time length, wherein the first value, the second value and the third time length are used for determining the first time length.

In one embodiment, the second value may be set according to actual requirements, and is exemplarily 0.

In one embodiment, where counting is performed in a count-down manner, it is understood that the second value is greater than the first value. At this time, the difference value obtained by subtracting the first numerical value from the second numerical value is multiplied by the third time length to obtain the first time length. For example, if the second value is 5, the first value is 0, and the third duration is 30 seconds, the first duration can be determined to be 150 seconds.

Of course, in another embodiment, the second value may also be sent to the freeze screen monitoring process by the system service process, and for example, the system service process may send the second value to the freeze screen monitoring process by using an enable signal, which is not limited in this embodiment of the present application.

The first time length is determined based on the first numerical value, the second numerical value and the third time length, and in addition, in the counting process, the screen freezing monitoring process restarts counting every time the screen freezing monitoring process receives the heartbeat packet sent by the system service process, so that if the screen freezing monitoring process detects that the counting value reaches the second numerical value, the heartbeat packet sent by the system service process is not monitored in the first time length.

It is worth mentioning that the frozen screen monitoring process determines whether the heartbeat packet sent by the system service process is not monitored in the first time period in a counting mode, so as to determine whether the system service process operates normally, and monitor the operating state of the system service process, so that the system is triggered to restart under the condition that the system service process operates abnormally, and the phenomenon that the system is blocked due to system crash is avoided.

It should be noted that, in the above steps 502 to 504, after the freeze screen monitoring process receives the enable signal sent by the system service process, the inter-process communication between the system service process and the freeze screen monitoring process is not monitored within the first time period.

Step 505: and triggering the system to restart by the frozen screen monitoring process.

In the counting process, the frozen screen monitoring process restarts counting every time the frozen screen monitoring process receives the heartbeat packet sent by the system service process, so that if the frozen screen monitoring process detects that the count value reaches the second value, the heartbeat packet sent by the system service process is not received for a long time, and the system service process can be determined to be abnormally operated, for example, the heartbeat packet cannot be sent to the frozen screen monitoring mechanism due to the failure of the watchdog monitoring mechanism. At the moment, in order to avoid the phenomena of screen blackness and the like caused by the system being stuck, the screen freezing monitoring process triggers the system to restart. For example, the frozen screen monitoring process calls the power-down interface to power down the system and then calls the underlying power-up interface periodically to restart the system.

As an example of the present application, taking counting including count down as an example, after the freeze-screen monitoring process receives an enable signal sent by the system service process, if the freeze-screen monitoring process receives a numerical value modification instruction, the first numerical value is updated to a third numerical value, the numerical value modification instruction carries the third numerical value, the third numerical value is greater than the first numerical value, the numerical value modification instruction is sent by the system service process when detecting that the system service running in the system service process is abnormal, where the abnormality is a situation that the system service process is blocked or a lock is held for a long time.

As described above, the electronic device may monitor the system service process running in the system service process through the watchdog monitoring mechanism in the system service process. When the watchdog monitoring mechanism monitors that the system service is abnormal, because part of the reliability detection scheme in the system starts to work at the moment, in order to not affect the normal operation of the reliability measurement scheme, in addition, the watchdog monitoring mechanism needs to execute other operations, such as needing to grab stack information, restoring the system service, and the like, and therefore the watchdog monitoring process needs to wait for a while, and a certain time is provided for the watchdog monitoring mechanism to restore the system service. Therefore, the system service process sends a numerical value modification instruction to the screen freezing monitoring mechanism to increase the first time length, so that the screen freezing monitoring process can monitor for a period of time more and then determine whether the system service process is abnormal.

As an example, referring to fig. 6, the system service process enables the freeze screen monitoring process and sends a first value of 5 to the freeze screen monitoring process, i.e. indicates the first value for the freeze screen monitoring process. The system service process starts a service monitoring mechanism, and the service monitoring mechanism monitors the system service in the system service process. When the service monitoring mechanism monitors that the system service in the system service process is abnormal in operation, the stack information is captured, and the screen freezing monitoring process is instructed to modify the first numerical value, for example, the first numerical value is 5, and the third numerical value is 6, that is, the system service process instructs the screen freezing monitoring process to modify the first numerical value to 6. In addition, it is understood that, in this case, the first time period is determined based on the modified first value, the modified second value, and the modified third time period.

As another example of the application, when the counting includes incremental counting, after the freeze-screen monitoring process receives an enable signal sent by the system service process, if the freeze-screen monitoring process receives a numerical value modification instruction, the first numerical value is updated to a fourth numerical value, the fourth numerical value is carried in the numerical value modification instruction, and the fourth numerical value is smaller than the first numerical value, where the numerical value modification instruction is sent by the system service process when the system service process detects that the system service in the system service process is abnormal.

That is, during the count-up process, to allow the first duration to increase, the system service process instructs the freeze monitor process to reduce the first value, e.g., the first value is 5 and the fourth value may be 4.

It is worth mentioning that, when the system service running abnormality in the system service process is detected, the system service process instructs the screen freezing monitoring process to adjust the first value so as to increase the first duration, thereby avoiding the system restarting under the condition that the watchdog monitoring mechanism can recover the abnormality of the system service.

It should be noted that, the above is described by taking the example of adjusting the first value when the system service is abnormal, and in another embodiment, if the second value is indicated by the system service process, the second value may be adjusted, or the first value and the second value may be adjusted to increase the first duration.

As an example of the present application, the frozen screen monitoring process receives a value resetting instruction, and updates the third value to the first value, where the value resetting instruction is sent by the system service process when it is detected that the system service is restored to normal.

For example, referring to fig. 6 again, after the service monitoring mechanism restarts the system service, the system service in the system service process returns to normal operation, and then the system service process sends a numerical value resetting instruction to the frozen screen monitoring process. After receiving the value reset command, the freeze monitor process modifies the first value to the value before receiving the value modification command, such as to 5, and starts to count again from 5.

It is worth mentioning that the system service process indicates the screen freezing monitoring process to modify the first value back to the original value after monitoring that the system service is recovered to be normal, so as to recover the monitoring duration of the screen freezing monitoring process.

In the embodiment of the application, a freeze screen monitoring process is started. After the frozen screen monitoring process receives an enabling signal sent by a system service process, if a heartbeat packet sent by the system service process is received within a first time period, the system service process is determined to be abnormal in operation, and at the moment, the frozen screen monitoring process triggers the system to restart in order to avoid the phenomena of screen blacking and the like caused by system crash, so that the problem that the system crash is caused by the fact that the system service process cannot normally operate is solved.

On the basis of the embodiment shown in fig. 3, please refer to fig. 7, fig. 7 is a flowchart illustrating a freeze screen monitoring method according to another exemplary embodiment, which is performed by the electronic device, by way of example and not limitation, and the method may include the following:

step 701: and starting a screen freezing monitoring process.

Step 702: and after the frozen screen monitoring process receives the enabling signal sent by the system service process, timing is started.

As an example, the freeze screen monitoring process starts to count up, for example, from 0, after receiving the enable signal sent by the system service process.

As another example, the freeze screen monitor process starts a countdown, such as from 150 seconds, after receiving the enable signal sent by the system service process.

Step 703: and in the timing process of the frozen screen monitoring process, whether the interprocess communication between the system service process and the frozen screen monitoring process is monitored.

And in the process of timing, the frozen screen monitoring process restarts timing every time the communication between the system service process and the frozen screen monitoring process is monitored.

As an implementation manner, in the timing process, each time a heartbeat packet sent by the system service process is received, the frozen screen monitoring process indicates that the system service process is currently in a normal running state, that is, the system service process is not abnormal. In this case, the freeze screen monitoring process restarts timing. Illustratively, the count-up timer is restarted, or the count-down timer is restarted.

Step 704: and the screen freezing monitoring process detects that the timing time reaches a first time, and determines that the inter-process communication between the system service process and the screen freezing monitoring process is not monitored in the first time.

In an embodiment, since the freeze screen monitoring process restarts timing after receiving a heartbeat packet sent by the system service process every time in the timing process, if the freeze screen monitoring process detects that the timing duration reaches the first duration, it indicates that the freeze screen monitoring process does not receive the heartbeat packet sent by the system service process within a longer period of time, that is, it is determined that the heartbeat packet sent by the system service process is not monitored within the first duration.

It should be noted that, in the above steps 702 to 704, after the freeze screen monitoring process receives the enable signal sent by the system service process, the interprocess communication between the system service process and the freeze screen monitoring process is not monitored in the first time period.

Step 705: and triggering the system to restart by the frozen screen monitoring process.

In an embodiment, in the timing process, timing is restarted when the frozen screen monitoring process receives the heartbeat packet sent by the system service process, so that if the frozen screen monitoring process detects that the timing duration reaches the first duration, it indicates that the heartbeat packet sent by the system service process has not been received within a longer time, and at this time, it may be determined that the system service process is abnormally operated. At the moment, in order to avoid the phenomena of screen blackness and the like caused by the system being stuck, the screen freezing monitoring process triggers the system to restart.

As an example of the present application, after the freeze screen monitoring process receives an enable signal sent by the system service process, if the freeze screen monitoring process receives a numerical modification instruction, the first time length is updated to a sixth time length, the numerical modification instruction carries the sixth time length, the sixth time length is greater than the first time length, and the numerical modification instruction is sent by the system service process when the abnormality of the system service running in the system service process is detected.

As another possible implementation mode, after the screen freezing monitoring process is enabled, when the system service process and the screen freezing monitoring process normally carry out interprocess communication, timing is not started, timing is started when the system service process is detected to be abnormal, and the system is triggered to restart when the first time length is exceeded.

In the embodiment of the application, a freeze screen monitoring process is started. After the frozen screen monitoring process receives an enabling signal sent by a system service process, if a heartbeat packet sent by the system service process is received within a first time period, the system service process is determined to be abnormal in operation, and at the moment, the frozen screen monitoring process triggers the system to restart in order to avoid the phenomena of screen blacking and the like caused by system crash, so that the problem that the system crash is caused by the fact that the system service process cannot normally operate is solved.

Referring to fig. 8, fig. 8 is a flowchart illustrating a method for freeze screen monitoring according to another exemplary embodiment, which is performed by the electronic device and is applied to a scenario of freeze screen monitoring during shutdown of the device, by way of example and not limitation, and the method may include:

step 801: and starting a screen freezing monitoring process.

The specific implementation of this method can refer to step 301 in the embodiment shown in fig. 3, and details are not repeated here.

Step 802: and after the frozen screen monitoring process receives an enabling signal sent by the system service process, determining that the electronic equipment cannot finish the process in the shutdown process, and triggering the system to restart.

In some embodiments, the ending process may also be referred to as a kill process, or may also be referred to as a kill process.

During the shutdown process of the electronic device, the init process usually ends up other processes. For example, in the shutdown process, the init process may send an end instruction to other processes in order according to a target process list in the system to end the other processes, where the target process list is used to record an end order of processes to be ended.

If the jelly screen monitoring process determines that the electronic equipment cannot end the process in the shutdown process, the shutdown is blocked, and the frozen screen monitoring process can trigger the system to restart.

As an example of the present application, the end timing of the freeze screen monitoring process is located after the end timing of the system service process. Normally, the system service process is located at the front of the target process list, i.e. the system service process is generally preferentially ended by the init process.

In the shutdown process, the time for the init process to finish the system service dropping process is earlier than the time for finishing the screen freezing monitoring process, that is, the system service process is finished before the screen freezing monitoring process.

As an example of the present application, the freeze monitor process is arranged at the end of a list of target processes in the system. That is, the frozen screen monitoring process is the last process that is ended by the init process.

It is worth mentioning that the screen freezing monitoring process is arranged at the tail position in the target process list, so that the screen freezing monitoring process can monitor more processes which cannot be finished in the shutdown process of the electronic equipment.

As an example of the present application, a case where a process cannot be ended during shutdown of an electronic device includes the following cases:

in the first case: and when the system service process is to be finished, the system service process is not found in the process running list.

Illustratively, when the init process determines the order of reaching the kill system service process according to the process sequence in the target process list, the system service process to be ended is illustrated. At this time, if the init process cannot find the system service process in the process running list, it indicates that the system service process is abnormally ended, and at this time, the electronic device may not end the process.

In the second case: and the system service process is not ended in a fifth time period after an ending instruction for ending the system service process is sent, wherein the fifth time period is longer than the time for normally ending the system service process.

Illustratively, the shutdown identifier is set, when the init process determines the order of reaching the kill system service process according to the process sequence in the target process list, the system service process to be ended is described, the init process finds the system service process in the process running list, and the init process sends an ending instruction for ending the system service process, but the kill system service process cannot be ended, so that the system service process is still in a running state within a fifth time period, and at this time, the system service process cannot be ended normally.

As an example of the present application, the process of determining that the electronic device cannot end the process in the shutdown process by the freeze screen monitoring process may be inferred based on a kill condition of the electronic device to itself (i.e., the freeze screen monitoring process) in the shutdown process. In one example, the specific implementation of determining that the electronic device cannot end the process during shutdown may include: and after receiving the enabling signal sent by the system service process, the screen freezing monitoring process counts every third time length from the first value, wherein the counting comprises count-down or count-up. And in the counting process of the frozen screen monitoring process, counting is started from the first numerical value again every time the heartbeat packet sent by the system service process is received. And under the condition that the count value does not reach the second numerical value, the frozen screen monitoring process receives a shutdown notification, and if the system service process is detected to be finished and a process finishing instruction for finishing the frozen screen monitoring process is not received within the fourth time, the process cannot be finished in the shutdown process.

The fourth time period may be set according to actual requirements, and is exemplarily the same as the first time period.

That is, the freeze screen monitoring process performs the counting operation after receiving the enable signal sent by the system service process. In the counting process, if the counting value does not reach the second value and the shutdown notification is received, the shutdown operation is executed currently, and at this time, the screen freezing monitoring process can inquire whether the system service process is finished or not. Under the condition that the system service process is detected to be finished, if a process finishing instruction for finishing the screen freezing monitoring process is not received within the fourth time length, the system shutdown is blocked, and the electronic equipment can be determined to be incapable of finishing the process in the shutdown process.

In one embodiment, the freeze screen monitoring process receives a shutdown notification from the init process. That is, in the shutdown process, the init process may send a shutdown notification to the frozen screen monitoring process in addition to ending other processes according to the target process list, so as to notify the frozen screen monitoring process that the shutdown operation is currently being performed. For example, the received shutdown notification may be a shutdown flag.

As an example of the present application, a specific implementation of the frozen screen monitoring process for querying whether the system service process is finished may include: and the frozen screen monitoring process inquires whether a system service process exists in the process running list, and if the system service process does not exist in the process running list, the system service process can be determined to be finished. Of course, if there is a system service process in the process run list, it may be determined that the system service process is not finished. Wherein, the process running list comprises the process in running state in the system.

In an embodiment, the fourth duration is the same as the first duration, and the specific implementation of the frozen-screen monitoring process detecting whether the process end instruction is received within the fourth duration may include: the frozen screen monitoring process starts counting from the first value, and if the process ending instruction is not received when the counting value reaches the second value, it can be determined that the process ending instruction is not received within the fourth time length. Conversely, if the process end instruction is received before the count value does not reach the second value, it may be determined that the process end instruction is received within the fourth time period.

It should be noted that, the above is an example process description that whether the process end instruction is received within the fourth time period by determining, in a counting manner, that the frozen-screen monitoring process detects whether the process end instruction is received within the fourth time period, in another embodiment, whether the frozen-screen monitoring process detects whether the process end instruction is received within the fourth time period may also be determined in a timing manner, which is not limited in this embodiment of the application.

Of course, it is understood that, in the case that the count value reaches the second value and the shutdown notification is not received, it indicates that the electronic device is not shutdown in the counting process, that is, the electronic device does not enter the shutdown procedure. In addition, in the counting process, counting can be restarted when the heartbeat packet sent by the system service process is received, so that the heartbeat packet sent by the system service process can be determined not to be received within the first time length, and in this case, the frozen screen monitoring process triggers the system to restart.

In one embodiment, the first duration is indicated by the system service process for the freeze screen monitoring process, or the first duration is preset.

In another embodiment, the second duration is a duration during which all system services in the system service process are monitored once, or the second duration is preset.

In the embodiment of the application, a freeze screen monitoring process is started. After the frozen screen monitoring process receives an enabling signal sent by a system service process, if it is determined that the electronic equipment cannot end the process in the shutdown process, the electronic equipment is shut down and stuck, and the frozen screen monitoring process triggers the system to restart, so that the problem of system crash caused by the fact that the process cannot be normally ended in the shutdown process is solved.

Referring to fig. 9, fig. 9 is a flowchart illustrating a method for freeze screen monitoring according to another exemplary embodiment, which may be applied to the electronic device, by way of example and not limitation, the method includes performing freeze screen monitoring during shutdown, and the method may include the following:

step 901: and starting a screen freezing monitoring process.

Step 902: and after the frozen screen monitoring process receives the enabling signal sent by the system service process, timing is started.

Step 903: and in the timing process of the frozen screen monitoring process, the timing is restarted every time the heartbeat packet sent by the system service process is received.

Specific implementation of steps 901 to 903 may refer to steps 601 to 603 in the embodiment shown in fig. 6, and details are not repeated here.

Step 904: and under the condition that the timing duration does not reach the first duration, the frozen screen monitoring process receives a shutdown notification, and if the system service process is detected to be finished and a process finishing instruction for finishing the frozen screen monitoring process is not received within the fourth duration, the process cannot be finished in the shutdown process.

That is, the freeze screen monitoring process executes the timing operation after receiving the enable signal sent by the system service process. In the timing process, if the timing duration does not reach the first duration and the shutdown notification is received, it indicates that the shutdown operation is currently being performed, and at this time, the frozen screen monitoring process may query whether the system service process is finished. Under the condition that the system service process is detected to be finished, if a process finishing instruction for finishing the screen freezing monitoring process is not received within the fourth time length, the system shutdown is blocked, and the electronic equipment can be determined to be incapable of finishing the process in the shutdown process.

In one embodiment, the freeze screen monitoring process receives a shutdown notification sent by the init process. That is, in the shutdown process, the init process may send a shutdown notification to the frozen screen monitoring process in addition to ending other processes according to the target process list, so as to notify the frozen screen monitoring process that the shutdown operation is currently being performed. For example, the received shutdown notification may be a shutdown flag.

As an example of the present application, a specific implementation of the frozen screen monitoring process for querying whether the system service process is finished may include: and the frozen screen monitoring process inquires whether a system service process exists in the process running list, and if the system service process does not exist in the process running list, the system service process can be determined to be finished. Of course, if there is a system service process in the process run list, it may be determined that the system service process is not finished. Wherein, the process running list comprises the process in running state in the system.

In an embodiment, a specific implementation that the frozen-screen monitoring process detects whether the process end instruction is received within the fourth duration may include: and starting timing by the frozen screen monitoring process, and if the process ending instruction is not received when the timing duration reaches the fourth duration, determining that the process ending instruction is not received in the fourth duration. Conversely, if the process end instruction is received before the timing length does not reach the fourth length, it may be determined that the process end instruction is received within the fourth length.

It should be noted that, the above is an example process description that whether the process end instruction is received within the fourth time period by determining, in a timing manner, whether the freeze-screen monitoring process detects that the process end instruction is received within the fourth time period, in another embodiment, whether the freeze-screen monitoring process detects that the process end instruction is received within the fourth time period may also be determined in a counting manner, which is not limited in this embodiment of the application.

Of course, it is understood that if the timing duration reaches the first duration and the shutdown notification is not received, it indicates that the electronic device is not shutdown in the counting process, that is, the electronic device does not enter the shutdown procedure. In the timing process, timing can be restarted when a heartbeat packet sent by the system service process is received, so that the heartbeat packet sent by the system service process can be determined not to be received within a long period of time.

It should be noted that, in the foregoing steps 902 to 904, after the freeze screen monitoring process receives the enable signal sent by the system service process, an exemplary specific implementation manner that the electronic device cannot end the process in the shutdown process is determined.

Step 905: and triggering the system to restart by the frozen screen monitoring process.

In the embodiment of the application, a freeze screen monitoring process is started. After the frozen screen monitoring process receives an enabling signal sent by a system service process, if it is determined that the electronic equipment cannot end the process in the shutdown process, the shutdown of the electronic equipment is blocked, and the frozen screen monitoring process triggers the system to restart, so that the problem of system crash caused by the fact that the process cannot be normally ended in the shutdown process is solved.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
