Description

Timed task execution method and display device

Technical Field

The invention relates to the field of display equipment, in particular to a timing task execution method and display equipment.

Background

In some application scenarios, a user may set a timing task through a display device, where the timing task is a task event that starts execution at a preset time, such as timing video recording, timing system upgrade, and the like. However, some timing tasks must be executed when the display device is in a power-on state, and once the user triggers a power key of the display device to power off or the user plugs a power plug of the display device, the timing tasks cannot be executed, which results in failure of the timing tasks.

Disclosure of Invention

The invention provides a timing task execution method and display equipment, which are used for solving the problem of failure of a timing task when the display equipment is in a non-starting state such as standby or power-off.

A first aspect provides a display device comprising:

the display device comprises a memory, a first display module and a second display module, wherein the memory is used for setting and storing a first identifier when the display device is switched to a non-power-on state, the first identifier is used for indicating the display device to execute a silent power-on mode, and the silent power-on mode is a mode of powering off and muting;

a controller configured to perform:

accessing the memory when receiving an instruction for switching to a non-starting-up state;

executing a silent starting mode when the first identifier is read;

when the completion of the starting is detected, acquiring a task to be executed from a timing task prestored in a database;

and starting to execute the task to be executed when the preset time is detected.

In the technical solution of the first aspect, when the controller receives a switch to a non-power-on state, the controller accesses the memory, and starts to execute a silent power-on mode when reading the first identifier, that is, the system is started but the display screen is off, and the sound player is silent, so that the display device is silently powered on in a state that the user does not perceive. In addition, before the display device is switched to the non-power-on state, for example, some timing tasks may be set when the display device is in the power-on state last time, and the timing tasks are stored in the database, the database may be updated according to the execution state of the timing tasks, for example, when a certain timing task is executed or has expired, the timing task is deleted from the database, when the silent power-on is completed this time, the controller may obtain a to-be-executed task that is pre-stored but has not been executed until the current time, the to-be-executed task is generally set by the user to be started at the preset time, and when the preset time is reached, the to-be-executed task is controlled to be started. The keep-alive mechanism of the timing task of the application is as follows: on one hand, through the first identification stored in the memory, when the equipment is switched to the non-power-on state, the silent power-on is started spontaneously, so that a user can not sense that the display equipment is changed into the power-on state, the timing task can be kept alive and executed on time, and the reduction of the power consumption of the display equipment is facilitated; on the other hand, the timing tasks set by the user are recorded in the database in advance, so that the controller can accurately acquire the tasks to be executed after silent startup and execute the tasks at regular time. By the two mechanisms, the problem of failure of the timing task can be solved.

In a first exemplary implementation manner of the first aspect, before the silent power-on is completed, the controller is further configured to perform: if a starting instruction is received, the silent starting mode is exited, and a normal starting mode is executed; controlling the memory to cancel storing the first identification. In the implementation mode, considering that the user is unaware of the silent startup, in the silent startup process, the user may execute the startup operation, and then quit the silent startup mode, and then execute the normal startup mode, in the normal startup mode, the user may perceive the startup process, and the memory cancels the storage of the first identifier, that is, the memory does not record the first identifier representing the silent startup during the normal startup.

In a second exemplary implementation manner of the first aspect, after obtaining the task to be executed, the controller is further configured to perform: re-accessing the memory; and controlling the display equipment to keep a normal starting state when detecting that the first identifier does not exist in the memory. In the first implementation mode, the memory cancels the storage of the first identifier, and the controller can know that the display device is started in a normal starting mode if no first identifier is detected when the memory is accessed again, so that the display device can keep the normal starting state, the backlight of the display device is lightened in the normal starting state, and the sound player can play sound normally.

In a third exemplary implementation manner of the first aspect, after the task to be executed is obtained, the controller is further configured to perform: re-accessing the memory; and when the first identification is read, if the current time does not reach the preset time, controlling the display equipment to enter a sleep state. In the implementation mode, when the controller accesses the memory again, if the first identifier can be read, the controller can know that the display device is started in the silent starting mode, and when the task to be executed is obtained, if the preset time is not reached currently, which indicates that no timing task needs to be executed at this time, the working state of the display device is controlled to be the sleep state, so that on one hand, the power consumption of the device can be reduced, and on the other hand, a keep-alive condition is provided for the subsequent execution of the timing task.

In a fourth exemplary implementation manner of the first aspect, the controller is further configured to perform: and when the preset time is detected, controlling the display equipment to be switched from the sleep state to the power-on state, and starting to execute the task to be executed. In a third implementation manner, the display device is put into a sleep state, and considering that most timing tasks need to be executed in the power-on state, when the preset time for starting the timing tasks is reached, the sleep state is exited first, the device is awakened, the state of the display device is switched to the power-on state, and then the tasks to be executed are executed. Optionally, the power-on state described herein may be a normal power-on state, or a silent power-on state, where the silent power-on state refers to that the display device is powered on and is turned off, and the sound player is silent. Specifically, whether to light the screen or not and remove the mute can be determined according to the type of the timing task.

In a fifth exemplary implementation form of the first aspect, the memory is further configured to store the first identifier in a target flag bit. In the implementation mode, a fixed target zone bit can be set in the memory, and the stored value of the target zone bit can be adaptively modified according to the device boot mode, that is, the target zone bit is equivalent to a zone bit for indicating and recording the device boot mode, the first identifier can be stored in the target zone bit, and when the controller accesses the controller, the target zone bit is directly read.

In a sixth exemplary implementation manner of the first aspect, the controller is further configured to cancel storing the first identifier as follows: and the control memory changes the value of the target zone bit from the first identifier to a second identifier, and the second identifier is used for indicating the display equipment to execute the boot operation in a normal boot mode. For example, when the value of the target flag bit is set to 1, the value "1" read by the controller is the first identifier, and when the first identifier needs to be cancelled, the value of the target flag bit is set to 0, and the value "0" read by the controller is the second identifier. By setting the target zone bit, the controller can quickly and accurately know whether the first identifier or the second identifier is currently stored in the memory by reading the fixed zone bit.

In a seventh exemplary implementation manner of the first aspect, the instruction to switch to the non-power-on state is generated when detecting that the power supply is unplugged and powered back, or the instruction to switch to the non-power-on state is generated when detecting a power-off operation. In this example, two scenarios are provided, one is to plug and unplug the Power plug of the display device, and the other is to trigger the Power key to Power Off (i.e., power Off), which are both scenarios where the timing task fails due to switching to the non-Power-Off state, but are not limited to other scenarios.

In an eighth exemplary implementation manner of the first aspect, the controller is further configured to perform: and if the task to be executed is not acquired from the database, controlling the display equipment to enter a sleep state or controlling the display equipment to be powered off. In the implementation mode, the controller does not acquire the task to be executed in the database, and then does not need to execute any timing task subsequently, and because the silent startup mode user does not sense the startup operation, the user may not perform operation control on the display device, so that the working state of the device can be directly set to be a sleep state or a shutdown state in order to reduce the power consumption of the device.

The timing task execution method provided by the second aspect comprises the following steps:

when an instruction of switching to a non-starting-up state is received, accessing a memory;

executing a silent starting mode when the first identifier stored in the memory is read; the silent starting mode is starting in a screen-off and silent mode;

when the completion of the starting is detected, acquiring a task to be executed from a timing task prestored in a database;

and starting to execute the task to be executed when the preset time is detected.

Other exemplary implementations and advantages included in the second aspect may be adaptively referred to in the description related to the first aspect, and are not described herein again.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs may be windows (windows) programs carried by an operating system, system setting programs, clock programs or the like; or an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The 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. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display driver, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (like fingerprint sensor, temperature sensor, pressure sensor etc.) and power drive etc..

The above embodiments describe the hardware/software architecture and functional implementation of the display device. In some application scenarios, when the display device is in a normal power-on state, the user may set a timing task in advance, such as timing video recording, timing system upgrade, and the like. The content of the timed task includes preset time and task event, that is, corresponding task event is executed at preset time, as an example only, assuming that the timed task S is { 09 20/05/25/2021, reservation upgrading system }, when the display device detects that the system time reaches 09/05/25/2021, the task flow of system upgrading is automatically started.

More timing tasks can be effectively executed only when the display device is in a power-on state, and in practical application, certain behaviors of a user can cause the timing tasks to be invalid, for example, the user can unplug a power supply, so that the display device is completely powered off, and the power-on action is not executed after the power supply is reconnected; for example, when the display device is in a normal power-on state, the user presses the power key for a long time to actively execute a power-off action, and the display device cannot execute a timing task after being powered off. If the timing task fails, adverse effects can be caused, for example, in some countries or regions, the timing recording of videos and the like are the charge items of televisions, and once the timing task fails, not only can the customers not record and watch interested videos, but also the benefits of television manufacturers are influenced. Therefore, when a user switches the display device to the non-power-on state, how to keep the timing task alive is achieved, and the problem that the timing task which is not executed yet fails is solved.

In order to solve the above technical problems, the present application provides a mechanism for pre-storing a timing task based on a silent boot mode and a database, so as to implement fixed-point punctual execution of the timing task.

In an exemplary implementation, the display device may execute the silent power-on mode when receiving an instruction to switch to the non-power-on state in the power-on state. The silent power-on mode is a mode of turning on the display in a screen-off and silent mode, that is, the backlight of the display is not lit, so that the display appears as a black screen, and the current sound player does not output sound or plays sound in the silent mode, wherein the sound player includes but is not limited to a built-in speaker of the display device or a connected external power amplifier. Because the video/image angle of the display and the audio angle of the sound player limit the audio and video externalization presentation of the display device, the user can completely perceive the silent startup executed when the display device is powered off/powered off, on one hand, the silent startup can reduce the power consumption of the display device, and on the other hand, the running state of the display device (i.e. the silent startup state which is not perceived by the user) can also provide the keep-alive condition for the timing task.

In some exemplary implementations, for a user to perform a power-off behavior, the display device no longer performs the native powermanager. Shutdownflow procedure, but instead is modified to send a first broadcast by the system service that notifies the particular memory that the display device has received the power-off instruction; and after receiving the first broadcast, a specific memory sets and stores a first identifier, wherein the first identifier is used for indicating the display equipment to execute the silent boot mode. Optionally, the memory is an EEPROM (Electrically Erasable Programmable Read Only memory).

For the behavior that the user powers off the power supply and then powers on again, the display device can directly enter the silent starting mode by default. In some exemplary implementation manners, after the user plugs in or unplugs the power supply, the memory senses that the memory is powered on, and then the first identifier is automatically set and stored, and the bootloader in the display device reads the first identifier, that is, the boot process is started in the silent boot mode. It should be noted that the condition for triggering the memory to set the first identifier is not limited to that described in the embodiment of the present application, and may be specifically configured according to an operation of a user switching the device into a non-power-on state.

In some embodiments, the display device may maintain a database for storing timed tasks set by a user while the display device is in a normal on state. Optionally, if the timed task a is executed and completed, the timed task a may be deleted from the database; alternatively, rather than deleting timed task A, timed task A may be provided with an executed identifier that indicates that timed task A in the database has previously been executed to completion. Optionally, if the timing task B is not started to be executed at the preset time due to some abnormal factors, and when the display device recovers to normal operation, the system time already exceeds the preset time of the timing task B, so that the timing task B is disabled (expired), the timing task B may be deleted from the database, or the timing task B may not be deleted, but a failure flag is set for the timing task B, where the abnormal factors include, but are not limited to, power failure, device clock error, and the like. The database takes the form of setting identification, so that the executed and failed timing tasks do not need to be deleted, and all historical tasks can be recorded. Because the task information stored in the database is not lost due to the shutdown/power-off of the display device, when silent startup is completed, the timed task which is not executed and is not invalid by the current time, namely the task to be executed, can be obtained by accessing the database.

In an exemplary implementation, the display device may create a separate monitoring thread that detects the boot process.

In an exemplary implementation manner, when the monitoring thread detects that the silent boot is completed this time, the controller may obtain a task to be executed from a timing task pre-stored in the database. If the database adopts a mode of deleting executed and invalid timing tasks, namely the timing tasks currently stored in the database are all to-be-executed tasks; and if the database adopts a mode of setting the executed identification and the failure identification, screening out the timing tasks without any one of the two identifications from the database, namely obtaining the tasks to be executed.

In one exemplary implementation, the android system power supply can be divided into at least on, sleep, STR (Suspend to RAM, suspend to memory), power off, and AC off. Wherein, on is a normal working state/a normal starting state, namely a normal starting running state; sleep is a sleep state, such as including light sleep (e.g., active Standby) and deep sleep (mem); power off is in the power-off state; the AC off is a power-off state in which the power supply is not turned on.

In an exemplary implementation, the shallow sleep, such as Active Standby, in the shallow sleep state, the CPU is not powered off, and can still receive and process a specific event, and the CPU can recover to the normal operating state faster than STR, but relatively power is consumed, and a subsequent user can wake up the device system quickly through an external input device such as a remote controller, a mouse, or a keyboard. The deep sleep mode is, for example, a sleep state entered in the mem mode, and the system can only be woken up by a specific wake-up manner, for example, pressing a power key, but cannot be woken up by an external input device such as a remote controller. The STR is equivalent to a standby state, and in this state, data such as the current operating state of the system is stored in the memory, and at this time, power needs to be supplied to the RAM, so as to ensure that the system can be quickly restored to a normal operating state (on) in the following process, the tasks of the user state and the kernel state are frozen, devices such as a display and a remote controller are turned off, the system is awakened (for example, a power key is triggered) by using a specific mode, and the CPU stops operating.

In an exemplary implementation, the task to be executed may be empty, that is, the task to be executed is not acquired; or acquiring at least one task to be executed.

In an exemplary implementation manner, if the controller does not acquire the task to be executed, it indicates that the timed task is not required to be executed subsequently, and optionally, the display device may control the display device to be actually powered off (power off) without maintaining the keep-alive condition of the timed task, so as to reduce power consumption of the device, and start the power-on process in a normal power-on mode when the user performs a power-on action. Or, optionally, the display device may also be controlled to enter a sleep state (sleep), so as to facilitate quick wake-up of the device while reducing power consumption of the device to a certain extent.

In an exemplary implementation manner, if the controller obtains a non-empty task to be executed, the display device may be in a sleep state or a silent power-on state (black screen and silent) that is not perceived by the user, that is, the keep-alive condition of the timing task may be maintained, so as to ensure that the timing task is always valid. And controlling the task module to start to execute the task to be executed when the preset time is detected. As an example, assuming that a task C to be executed and a task D to be executed are obtained, the starting time of the task C to be executed is preset time 1, the starting time of the task D to be executed is preset time 2, and the preset time 1 is later than the preset time 2, when the controller detects that the system time reaches the preset time 2, the controller starts to execute the task D to be executed, and then starts to execute the task C to be executed again when the preset time 1 is reached.

In an exemplary implementation manner, the controller may form a task list according to the to-be-executed tasks acquired from the database, where the task list includes at least task information of one to-be-executed task. Optionally, the task information of each task to be executed in the task list is sorted according to the sequence of the preset time, for example, the earlier the sequence of the task to be executed is, the earlier the preset time is, the earlier the sequence of the task to be executed is, the earlier the sequence is, the controller can learn the execution sequence of the tasks to be executed in the time dimension. The controller executes each task to be executed in order according to the indication of the task list, so that the punctuality, the effectiveness and the orderliness of the execution of the timed tasks are ensured, and the omission of the execution of the tasks can be avoided.

In an exemplary implementation, since the user does not sense the silent boot, the user may think that the display device is currently in the off state, and during the silent boot (i.e. at the stage after the silent boot is started and before the silent boot is completed), if the user wants to use the display device, the user may input a boot instruction (e.g. execute power on), and then need to exit the silent boot mode, and execute the normal boot mode, where the normal boot mode allows the display to light the backlight, and may display videos/images such as boot animation, and the sound player outputs sound, i.e. executes the boot program of the android native system, and the user is aware of the normal boot mode.

In an exemplary implementation, the display device exits the silent boot mode and then executes the normal boot mode, and the memory is controlled to cancel storing the first identifier. Because the starting mode of the display equipment is converted, the storage state in the memory is changed by taking the latest starting mode after conversion as the standard, and the cancellation of the storage of the first identifier is equivalent to the recording that the display equipment is started in a normal starting mode instead of a silent starting mode; otherwise, if the controller does not receive the boot instruction in the silent boot process, the silent boot mode is maintained until the boot is completed, and the memory maintains the storage state of the first identifier.

It should be noted that, no matter the display device executes the silent boot mode or switches to the normal boot mode during the silent boot process, the manner of acquiring the task to be executed when the completion of the boot is detected and executing the task to be executed at a predetermined timing is consistent.

Referring to the above embodiments, in the silent boot process, the boot mode may be switched, which directly affects the running state of the display device after the boot is completed. Therefore, in an exemplary implementation manner, after the controller acquires the task to be executed, the controller needs to access the memory again, and if it is detected that there is no first identifier in the memory, the controller recognizes that the display device is powered on in a normal power-on mode, and the display device remains in a power-on (on) state, which supports a user to directly operate the display device.

In an exemplary implementation, after acquiring the task to be performed, in particular, the controller may control a power management (PowerManager) service to access the memory again, the power management service being used to manage and regulate the state of the display device. If the power management service reads the first identifier when accessing the memory again, that is, it is recognized that the display device is started in the silent starting mode, the controller may further query whether a target task exists according to the task list, where the target task is a timing task to be executed at the current time or within a threshold duration after the current time. For example, the current time when the controller queries the task list is T1, the threshold duration is T, and if the preset time of the timed task S falls within the interval [ T1, T1+ T ], the timed task S is the target task. After the target task is found, the controller controls the display equipment to recover to a normal working state from a silent starting state by controlling the power management service, including controlling the display to be on and controlling the sound player to output sound, so as to ensure that the timing task can be effectively executed, and immediately starting to execute the target task when the current time is detected to reach the preset time of the target task.

Due to the relative urgency and the proximity of the execution of the target task, in the embodiment, by setting the threshold duration t, the time for the display device to recover from the silent startup state to the normal working state is reserved, so that the problem that the target task is overdue and invalid due to the fact that the time for the display device to recover the normal working state exceeds the preset time of the target task is avoided.

In an exemplary implementation manner, if all the preset time of each timing task in the task list falls outside [ T1, T1+ T ], that is, the preset time is later than T1+ T, it is described that the target task is not queried, that is, the current time is considered to not reach the preset time of the task to be executed, no timing task needs to be started to be executed within a threshold duration, and optionally, the display device is controlled to enter a sleep (sleep) state, so that the power consumption of the device is reduced while the keep-alive condition of the timing task is maintained.

In an exemplary implementation, some timing tasks have to be executed in the power-on state, for example, a timing screen recording task, so after the display device is asleep, if the controller detects that the system time reaches a preset time of such tasks to be executed, the display device needs to be controlled to switch from the sleep state to the power-on state, that is, the display device starts to execute the tasks to be executed immediately after waking up the display device. Whether the normal power-on state or the silent power-on state is entered after the sleep state is exited depends on whether the timing task needs to be executed in the normal operating state of the display and the sound player.

In some exemplary implementation modes, when the display device is in an Active Standby state, the CPU can still process certain tasks and events in the state, so for timing tasks which do not require to be executed in a normal working state, such as timing upgrade applications, the timing tasks can also be executed in the Active Standby state without switching to the normal working state, and of course, the timing tasks can also be executed in the Active Standby state. When the timing task is executed, the operation state of the display device may be set according to factors such as the type of the task, and is not limited to the embodiment.

In an exemplary implementation manner, if the display device is turned on in the silent turn-on mode, each time a task to be executed is executed, if there are no other tasks to be executed in a subsequent time period, the display device may be controlled to maintain a normal working state, or may be controlled to switch to a sleep state until a preset time of a next task to be executed arrives, and the device is awakened again and started to execute the next task to be executed. In other application scenarios, if the controller receives power on operation/wake-up operation of the user after silent startup is completed, the subsequent controllable display device always keeps a normal working state, is not switched to other states, and executes each task to be executed in the task list in sequence.

In an exemplary implementation, for the timed task E with the failure identifier in the database, when the display device is in a normal power-on state, the user may be prompted, for example, through the UI, that the timed task E has failed, and asked whether the user resets the timed task. If the user selects to cancel, no new timing task is generated, and the database is not updated; and if the user selects to reset and modifies the preset time corresponding to the timing task E, generating a new timing task E ', and synchronously filling the new timing task E' into the database. In the implementation mode, the user can be prompted which failed tasks exist, and the user is supported to adjust the execution time of the failed task events additionally.

In one exemplary implementation, in order to facilitate the controller to quickly read the first identifier from the memory and quickly identify the type of power-on mode (silent power-on mode or normal power-on mode) adopted by the display device, a fixed target flag bit may be set in the memory, and the value of the target flag bit is used for characterizing the type of power-on mode. When the controller accesses the memory, the fixed target zone bit in the memory can be directly read, and the category of the starting mode can be rapidly distinguished by reading and identifying the current value of the target zone bit.

In an exemplary implementation manner, when the display device is in a power-on state, a user presses a power key for a long time to execute a power-off operation, the controller receives a power-off instruction, and the control system service sends the first broadcast; after the memory receives the first broadcast, the value of the target zone bit is set as a first identifier, and after the controller reads the target zone bit, the first identifier can be identified, and a silent starting mode is started to be executed.

In an exemplary implementation manner, when the user unplugs the power supply and then powers on again, the memory senses that the memory is changed from the power-off state to the power-on state, and the value of the target flag bit is automatically set as the first identifier. And the bootloader configured by the controller needs to access the memory and read the value of the target zone bit before executing boot, so that a boot process is started according to a boot mode matched with the current value of the target zone bit.

In some exemplary implementations, when a user inputs a power-on (power on) instruction, the value of the target flag bit of the memory is not the first identifier, and optionally, when the controller receives the power-on instruction, the control system service sends a second broadcast for notifying the memory that the display device has received the power on instruction; and after receiving the second broadcast, the memory can set the value of the target zone bit as a second identifier, wherein the second identifier is used for indicating the display equipment to execute a starting-up process according to a normal starting-up mode. And accessing the memory by the bootloader, reading that the current value of the target zone bit is a second identifier, and starting a normal starting mode.

In some exemplary implementations, the first identifier and the second identifier are preset identifiers, and the identifiers may be numbers, letters, or other forms, which are not limited in this embodiment of the application. For example, when the value of the read target flag bit is 1, the bootloader starts a silent boot mode, that is, the first flag is 1; if the value of the target flag bit is read to be 0, the bootloader starts the normal boot mode, i.e. the second flag is 0.

In some exemplary implementations, in a period from the start of the silent boot to the completion of the boot, if the controller receives the boot instruction, for example, the controller may use a control system service to send a second broadcast, and control the memory to change the value of the target flag bit from the original first identifier to the second identifier, exit the silent boot mode, and switch to the normal boot mode. When normal startup is completed, the tasks to be executed are obtained, then the memory is accessed again by a power management (PowerManager) service, the target flag bit of the memory is read, when the second identifier is read, the display equipment is known to be started up in a normal startup mode, the display equipment is controlled to be kept in a normal startup state (bright screen and sound), and each task to be executed is executed in sequence by the subsequent display equipment in the normal startup state all the time.

According to the method and the device, when the display equipment is in a starting state, if an instruction of switching to a non-starting state is received, starting is carried out in a silent starting mode without perception of a user based on an instruction of a first mark in a storage, when starting is completed, tasks to be executed can be accurately acquired based on timing tasks prestored in a database, each timing task which is not executed and not invalid can be executed on time under the running environment that the display equipment meets the timing task keep-alive condition, and the problem that the timing tasks are invalid due to overdue due to shutdown/power-off of the display equipment is solved.

Referring to the above description of the embodiments and referring to fig. 5, the present application provides a method for executing a timed task, where an execution subject of the method is a controller 250, and the method includes the following program steps:

step S101, when receiving the command of switching to the non-starting state, accessing the memory.

Step S102, when the first mark is read, executing a silent starting mode. The silent starting mode refers to starting in a screen-off and silent mode, and a user cannot sense silent starting.

And step S103, when the completion of the starting is detected, acquiring a task to be executed from a timing task prestored in a database.

And step S104, judging whether the task to be executed is acquired. If the task to be executed is obtained, executing step S105; if the task to be executed is not acquired, step S109 is executed.

Step S105, detecting whether a preset time is reached. The preset time is the preset starting time of the task to be executed. If the system time does not reach the preset time, executing step S106 and step S107; if the system time reaches the preset time, step S108 is executed.

And S106, controlling the display device to enter a sleep state.

And S107, when the preset time is detected, controlling the display equipment to be switched from the sleep state to the normal power-on state, and starting to execute the task to be executed.

And step S108, starting to execute the task to be executed.

In other implementations, before performing step S107 and step S108, it may be determined whether the display device needs to be restored to the normal power-on state according to the event type of the task to be executed. If the task in step S107 can be executed in the sleep state, or the task in step S108 can be executed in the silent power-on state (powered on, but turned off and muted), the device may not need to be restored to the normal operating state. If the task cannot be executed in the sleep state in step S107, the display device is woken up by exiting the sleep state, so that the display device is restored to the normal operating state and then the task is executed. If the task cannot be executed in the silent power-on state in step S108, the display is controlled to light the backlight, and the audio player is controlled to start executing the task after audio output. In short, when the timed task is executed, the state of the display device may be made to satisfy the execution condition of the timed task.

Step S109, controlling the display device to enter a sleep state, or controlling the display device to power off.

In some embodiments, after silent startup is completed, if a task to be executed is not obtained, the display device can be changed from the current silent startup state to the sleep state without executing any timing task, so that the power consumption of the device is reduced to a certain extent, and a user can quickly wake up the device after clicking a power key; or, the display device is directly turned off, thereby maximally reducing power consumption of the device when the timing task is not required to be executed and the user does not operate the device.

As shown in fig. 6, the present application also provides another timing task execution method, where an execution subject of the method is a controller 250, and the method includes the following program steps:

in step S201, when an instruction to switch to the non-boot state is received, the memory is accessed.

Step S202, when the first identifier is read, executing a silent boot mode.

In step S203, when the power-on command is received, the silent power-on mode is exited and the normal power-on mode is switched to.

And step S204, controlling the memory to cancel storing the first identifier.

Step S205, when it is detected that the booting is completed this time, a task to be executed is obtained from a timing task pre-stored in the database.

And step S206, accessing the memory again, and controlling the display equipment to keep a normal starting state when detecting that the first identifier does not exist in the memory.

Step S207, determining whether the task to be executed is acquired. If the task to be executed is acquired, executing step S208 and step S209; if the task to be executed is not acquired, step S210 is executed.

Step S208, detecting whether a preset time is reached. The preset time is the preset starting time of the task to be executed. If the system time does not reach the preset time, continuing to execute step S208; if the system time reaches the preset time, step S209 is executed.

Step S209, starting to execute the task to be executed.

Step S210, no timing task is performed. When the task to be executed is not acquired, any timing task does not need to be executed, the display equipment keeps the current situation and responds to an operation instruction input by a user.

In an exemplary implementation, the controller 250 performs overall control, and in particular implementations, the controller 250 may optionally implement the required functions by issuing control commands to the underlying units/services.

In an exemplary implementation, the controller 250 issues a control command to the system service according to the shutdown/startup operation of the receiving user, so that the system service sends broadcast information to notify the memory to set the value of the target flag.

In an exemplary implementation, the controller 250 issues a control command to the bootloader to enable the bootloader to access the memory and read the value of the target flag bit, so as to determine the boot mode to be started.

In an exemplary implementation, when the silent boot mode is started, the bootloader is controlled to send a screen-off instruction to the display and send a mute instruction to the sound player.

In an exemplary implementation, the controller 250 may establish a monitoring thread for monitoring the boot process in the normal boot mode or the silent boot mode, and the controller 250 may acquire the boot process through the monitoring thread.

In an exemplary implementation manner, when the boot is completed, the controller 250 issues a control instruction to the task management module, so that the task management module obtains the tasks to be executed from the database to form a task list, and implements, through an instruction of the task list, sequential execution of the tasks to be executed in the time dimension.

In an exemplary implementation manner, after the task list is obtained, when the preset time 3 is about to be reached, the controller 250 issues a control instruction to a task module corresponding to the timed task F, so as to control the task module to start executing the timed task F at the time of the preset time 3.

In an exemplary implementation, the controller 250 issues a control command to the power management service to enable the power management service to switch or maintain the state of the display device, where the state of the display device includes a power-on state (including a normal power-on state and a silent power-on state), a sleep state (including an Active Standby state), and a power-off state.

It should be noted that the communication and control logic between the controller and the bottom layer is not limited to that shown in the embodiment of the present application, and in addition, the bottom layer unit/service may be set according to the system architecture and the actual function, so as to enable the keep-alive condition and the task execution logic of the timing task in the present application.
