In some embodiments, the control and operation of the display device can be realized by using a voice assistant function, the voice assistant function is configured in the display device, and the display device collects voice information of a user in real time to execute corresponding actions, so that the function of controlling the display device by voice is realized.

In order to enable the display device to be in the standby mode, a user can directly issue a voice instruction to the display device through the awakening word and can awaken the display device to enter a normal operation state in real time, the voice assistant function needs to be kept in an on state all the time in the standby mode.

In order to implement wake-up, WakeLock (wake-up lock) is configured in the Android system of the display device, and in some embodiments, WakeLock (wake-up lock) is a core mechanism for power consumption management of the Android system, and includes the following four types: PARTIAL _ WAKE _ LOCK, SCREEN _ DIM _ WAKE _ LOCK, SCREEN _ BRIGHT _ WAKE _ LOCK, FULL _ WAKE _ LOCK. In some embodiments, the application may be in a running state by holding a wakelock LOCK with a PARTIAL _ WAKE _ LOCK type, and after the application applies for the LOCK, while the display device is in a standby state, although the display is turned off, other modules are in a running state all the time.

For example, when the far-field voice application holds a PARTIAL _ WAKE _ LOCK, and receives a standby instruction, on one hand, the display device may execute a process of entering an STR standby state, resulting in a bluetooth service, a Wi-Fi service, and the like being closed, so that a connection between the remote controller and the display device is disconnected, and the display device cannot be woken up through the near-field voice service, that is, a full standby mode; on the other hand, since the far-field speech application applies for the PARTIAL _ WAKE _ LOCK, after the STR standby state procedure is executed, the display device does not really enter standby, for example, the display is turned off, but the microphone module and the like are still in operation, i.e., in a false standby mode.

It should be noted that the application holding the PARTIAL _ WAKE _ LOCK LOCK needs to go through the WakeLock application process. When the method is applied to the application of WakeLock, an acquire () method or an acquire (locking timeout) method is called, after the application calls the acquire () method or the acquire (locking timeout) method, the PM module calls the acquire Lock () method to apply for the WakeLock, the acquire Lock () method is called downwards, and the PowerManagerService process carries out processing.

Specifically, the PowerManagerService process calls an acquireLocke () method, in the acquireWakeLock () method, firstly, WakeLock type check is carried out to avoid invalid WakeLock types, then, permission check is carried out, namely, whether the application has android.

In the acquirewakelocklnternal () method, firstly, whether WakeLock already exists is searched through a first parameter IBinder, if yes, instantiation is not carried out, and an attribute value of the WakeLock is updated on the original WakeLock; and if the WakeLock does not exist, creating a WakeLock object, and simultaneously saving the WakeLock object in the List to obtain the WakeLock instance. And subsequently, judging whether the acquired WakeLock is available or not by a setWakeLockDisabledStateLocked () method, and setting a disable attribute value of the WakeLock instance to indicate whether the WakeLock is unavailable or not according to the judgment result. Next, a judgment is made as to whether to directly light the SCREEN, and if the WakeLock is obtained with an acquired _ cause _ WAKE flag and the WakeLock type is one of SCREEN _ DIM _ WAKE _ LOCK, SCREEN _ BRIGHT _ WAKE _ LOCK and FULL _ WAKE _ LOCK, the SCREEN is directly woken.

And calling an updatepowerstateLockend () method, wherein the updatePowerStateLockend () method is a core method in the whole PowerManagerservice and is also the most important method in the whole PowerManagerservice and is used for updating the change of the whole power state and recalculating. In the updatePowerStateLocked () method, a key method is called: the method determines whether to apply for mWakeLockSuspendblock according to whether the current system holds a PARTIAL _ WAKE _ LOCK type LOCK, and then determines whether to apply for mDisplaySuspendblock according to whether the current system needs to screen bright.

And if lock application is required, calling an a cquire () method in a Sus pend Blocker interface, and after the acquire () method is called, calling a native Acquire Suspodbocker () method by the JNI layer to execute the lock application operation.

In addition, after the updatePowerStateLocked () method is executed, if a new WakeLock instance is created, the notifyAcquire value is true, and the Notifier is notified by the notifyWakeLockAcquiredLocke () method, and the Notifier starts timing according to the time applied by the WakeLock and judges whether the lock is a lock which is held for a long time according to the timing.

The WakeLock application process ends.

It can be understood that when an application holding a PARTIAL _ WAKE _ LOCK exists in the display device, the display device cannot enter a sleep state, resulting in excessively fast power consumption. Therefore, after the corresponding task is executed, the PARTIAL _ WAKE _ LOCK held by the application needs to be released in time. If the lock is a time-out lock applied by an acquire (longtimeout) method, the lock is automatically released after the time-out time is reached, and if the lock is a permanent lock applied by an acquire () method, the lock must be explicitly released.

The application release WakeLock procedure includes: and calling a release () method by the application, wherein the release WakeLock () method is called to the next layer of PowerManagerService in the release () method. After the authority check is performed in the releaseWakeLock () method, the releasewakelocklnternal () method is called.

In the method of releaseWakeLockInternal (), firstly, whether WakeLock exists is searched, and if the WakeLock does not exist, the WakeLock is directly returned; then check if there is a flag value that affects the release behavior and finally call the removeWakeLockLocked () method.

In the removeWakeLockLocke () method, the WakeLock with the ON _ AFTER _ RELEASE flag is processed by a notifyWakeLockReleaseLocke () method, which comprises the following steps of calling an applyWakeLockFlagsOnReleaseLocke () method to realize: when the Wakelock has the ON _ AFTER _ RELEASE mark, the lock is released, the display is kept ON for a period of time, and then the screen is extinguished.

Finally, the method of updatePowerStateLocked () is called, similar to the process of applying for locks, and in the method of updatePowerStateLocked () a key method is called: the updatesubsublocklocked () method determines whether to release a LOCK based on whether the current system holds a LOCK of the PARTIAL _ WAKE _ LOCK type, and then determines whether to release the LOCK based on whether the current system is to screen up.

And if the lock is to be released, calling a release () method in a Sus pend Blocker interface, and after the release () method is called, calling a native releaseSlusesPredblocker () method by the JNI layer to execute the operation of releasing the lock.

The WakeLock release process ends at this point.

In one type of application scenario, if the display device supports far-field voice service and the far-field voice application holds a PARTIAL _ WAKE _ LOCK, the display device may enter a standby mode after receiving a standby instruction.

In some embodiments, the standby mode may be an STR (Suspend To RAM, also called memory standby mode) standby state. In the STR standby state of the display apparatus, the controller in the display apparatus controls only the power supply circuit to maintain power supply to the RAM and the MCU, while other hardware, such as the display, the bluetooth module, the MIC module, the SOC module, etc., is in a power-down state (off state). Therefore, the overall power consumption of the display device can be reduced when the display device is in the STR standby state.

In order to enable the display device to support the voice assistant function, the display device needs to enter a pseudo standby mode when the display device is turned off, namely, a state that a CPU runs and a screen is turned off, at this time, an audio module and a video module are turned off, and other modules work normally. The display device usually adopts an MIC module to collect voice information, so as to realize the function of voice assistant. However, in the pseudo standby mode, the MIC switch for controlling the MIC module is normally turned off, so that the display apparatus cannot acquire audio information, the voice assistant function is naturally disabled, the display apparatus unnecessarily enters the pseudo standby mode, and power consumption of the display apparatus is too large.

Therefore, in order to ensure that the power consumption of the display device is not too large and the on state of the voice assistant function can be maintained, the embodiment of the invention provides the display device, so that the on and off states of the MIC switch are associated with the energy-saving mode of the display device, namely when the MIC switch is turned off, the display device enters a complete standby mode when the display device is turned off, and at the moment, the voice assistant function cannot work, and unnecessary power consumption is avoided; when the MIC switch is turned on, the display equipment enters a false standby mode when being turned off so as to ensure that the voice assistant function can work normally.

Referring to fig. 6, in order to enable the display device to generate more power consumption when entering the power saving mode, an embodiment of the present invention provides a display device 200, including: a display 260, a MIC switch 233, and a controller 250, the display 260 configured to present a user interface; the MIC switch 233 is configured to control the on and off of the MIC module (sound collector in fig. 3); in the display device in the standby mode, the MIC module collects voice data including a wakeup word sent by a user, and transmits the voice data to the controller 250; the controller 250 receives the voice data, recognizes that the voice data contains a wake-up word after local recognition processing, then the controller 250 determines a voice wake-up instruction for waking up the display device according to the recognition result, and triggers the SOC module to enter a working state, thereby realizing that the display device is woken up from a standby mode to enter an operating mode.

FIG. 7 illustrates a display diagram of a system settings menu according to some embodiments. The controller 250 is connected to the display 260 and the MIC switch 233, and a power saving (secure mode) switch for controlling the on and off of the power saving mode is configured in the controller 250, and referring to fig. 7, the power saving switch is located in a system setting menu in the controller, and the power saving switch is used for switching the display device into different power saving modes. The energy-saving mode comprises a complete standby mode and a false standby mode, wherein the false standby mode is that only the audio and video modules are turned off, and the other modules work normally; the complete standby mode is to turn off the main chip and all peripheral equipment, and only the singlechip works.

Figure 8 illustrates a flow diagram of a method of implementing a MIC switch association power saving mode, according to some embodiments. In the display device provided in the embodiment of the present invention, the MIC switch is associated with the energy saving mode to ensure that the display device in the standby state can not only start the voice assistant function, but also ensure that the power consumption is not too high, and for this reason, referring to fig. 8, when executing the implementation method of the MIC switch associated energy saving mode, the controller is configured to execute the following steps:

s1, establishing an incidence relation between the power-saving switch and the MIC switch, wherein the incidence relation means that the power-saving switch is turned on when the MIC switch is in an on state; when the MIC switch is in the off state, the power saving switch is turned off.

In order to associate the MIC switch with the energy-saving mode of the display device and control the display device to enter different energy-saving modes according to the state of the MIC switch, in some embodiments, an association relationship between the power-saving switch and the MIC switch is established first.

In order to avoid the display equipment from entering an unnecessary false standby mode, the power-saving switch is associated with the MIC switch to realize energy saving, namely, when the MIC switch is in an open state, the power-saving switch is opened; when the MIC switch is in the off state, the power saving switch is turned off.

And S2, responding to an equipment shutdown instruction for controlling the display equipment to execute shutdown actions, and acquiring the on-off state of the MIC switch, wherein the on-off state comprises an on state and an off state.

When the user controls the display equipment to be powered off, the power-off button on the remote controller is triggered to generate an equipment power-off instruction. The controller executes a shutdown action in response to the device shutdown instruction.

After the display device is shut down, the display device usually enters a standby mode under the condition that a power supply is not disconnected, and the display device is in a complete standby mode at the moment, namely, only the MCU module (singlechip) works, and the rest modules are all closed.

And because the display equipment is used for supporting the voice assistant function, the display equipment can be awakened through voice at any time after the display equipment is required to be shut down, namely the display equipment is required to enter a false standby mode, and at the moment, the MIC module is in an open state so as to collect a voice instruction of a user in real time and awaken the display equipment to enter a normal working mode.

Therefore, in order to ensure that the display device avoids generating unnecessary power consumption, whether the current display device needs to enter a pseudo standby mode or a full standby mode is determined according to the on-off state of the MIC switch.

In some embodiments, the controller acquires the on-off state of the MIC switch in real time after responding to the device shutdown instruction, so as to accurately control the display device to enter the corresponding energy-saving mode.

The display apparatus may support two acquisition mechanisms when acquiring the on-off state of the MIC switch. In some embodiments, the controller, in performing obtaining the switch state of the MIC switch, is further configured to perform the steps of:

and step 211, acquiring a state event of the MIC switch reported by the driver layer to the Android layer, wherein the driver layer and the Android layer are both configured in the controller.

Step 212, determining the switch state of the MIC switch based on the state event of the MIC switch.

In one of the acquisition mechanisms, a driver layer and an Android layer are configured in a controller, the driver layer reports a state event of an MIC switch to the Android layer in real time, the state event records the switch state of the MIC switch, and the MIC switch can be determined to be in an open state or a closed state currently according to the state event of the MIC switch.

In some embodiments, the controller, in performing obtaining the switch state of the MIC switch, is further configured to perform the steps of:

and step 221, invoking a switch detection service, and circularly detecting the switch state of the MIC switch.

And step 222, recording the changed switch state of the MIC switch when the switch state of the MIC switch is changed.

In another acquisition mechanism, a service is started on the Android side, that is, a switch detection service is called for circularly detecting the switch state of an MIC switch.

The switch detection service records the changed state each time the state of the MIC switch is detected to change. Thus, the switching state of the MIC switch may be determined based on the last recorded state.

Based on the determined on-off state of the MIC switch, the state of the power saving switch can be set to control the energy saving mode.

And S3, if the MIC switch is in the on state, controlling the power saving switch to start the false standby mode based on the association relation.

When the MIC switch is in an open state, the power-saving switch can be set to be in the open state according to the established association relation, and then the pseudo standby mode is started, so that the display equipment enters the pseudo standby mode, at the moment, the display equipment supports the voice assistant service, and the voice instruction of the user can be collected through the MIC module in real time to awaken the display equipment to enter a normal working state.

And S4, if the MIC switch is in the closed state, controlling the power saving switch to start the full standby mode based on the association relation.

When the MIC switch is in a closed state, the power-saving switch can be set to be in the closed state according to the established association relation, and then the full standby mode is started, so that the display equipment enters the full standby mode, at the moment, the display equipment does not support the voice assistant service any more, and the MIC module is closed, so that the power consumption of the display equipment is reduced.

Therefore, the display device provided by the embodiment of the invention can accurately control the display device to enter different energy-saving modes according to the on-off state of the MIC switch, and avoids the phenomenon that the display device enters an unnecessary false standby mode to generate larger power consumption due to the fact that the voice assistant function is unavailable because the MIC switch is closed in the false standby mode.

To facilitate prompting the user that the display device enters different power saving modes, a prompt may be generated to inform the user when entering the power saving mode.

In some embodiments, the controller is further configured to perform the steps of: and when the power saving switch starts the false standby mode, generating a false standby prompt and displaying the false standby prompt in a user interface.

When entering the false standby mode, the controller generates a false standby prompt and displays the false standby prompt in a user interface in the display to prompt a user that the display equipment enters the standby state, but the voice assistant function is started, and the display equipment can still be awakened to enter the normal working state through a voice instruction.

In some embodiments, the controller is further configured to perform the steps of: and when the power saving switch starts the full standby mode, generating a full standby prompt and displaying the full standby prompt in a user interface.

When entering the full standby mode, the controller generates a full standby prompt and displays the full standby prompt in a user interface in the display to prompt a user that the display equipment completely enters the standby state, the voice assistant function is turned off, the display equipment cannot be awakened to enter the normal working state through a voice instruction, and the display equipment can be awakened in other manual touch modes.
