It should be understood that Fig. 5 shows part of the connection relationship between the system management module and the USB module, and the rest of the connection relationship can refer to the current terminal The connection relationship in the device. Based on the structure shown in FIG. 5 , the method for reducing the power consumption of the terminal device provided by the embodiment of the present application will be described below in combination with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 6 is a schematic flowchart of an embodiment of a method for reducing power consumption of a terminal device provided in an embodiment of the present application. Referring to Figure 6, the method for reducing the power consumption of terminal equipment provided by the embodiment of the present application includes:

S601. The system management module sends a first message to the USB module in response to detecting that the terminal device is in the long standby state, where the first message is used to instruct the terminal device to enter the long standby state.

It should be understood that the long standby state means: the screen-off duration of the terminal device is greater than or equal to a preset duration, and the terminal device is in a static state. In one embodiment, the user may press a switch button on the terminal device to turn off the screen of the terminal device. Alternatively, the user does not operate the touch screen of the terminal device for a long time (such as the first period of time), and the screen of the terminal device is turned off. In this embodiment of the present application, there is no limitation on the method of turning off the terminal screen. The system management module may detect that the screen of the terminal device is off, and then, in response to detecting that the screen of the terminal is off, start recording the duration of the screen of the terminal device to obtain the duration of the screen of the terminal device. In an embodiment, the system management module may determine whether the screen of the terminal device is off based on a broadcast message from the system. Wherein, when the system management module receives a screen-off broadcast message from the system, it detects that the screen of the terminal device is off.

In one embodiment, the terminal device includes a gyroscope, an acceleration sensor, etc., and the gyroscope, the acceleration sensor, etc. can collect the motion state data of the terminal device, and report it to the system management module. The motion state of the device. When the off-screen duration of the terminal device is greater than or equal to the preset duration, and the terminal device is in a static state, the system management module determines that the terminal device is in a long standby state. In the embodiment of the present application, the process of how the system management module acquires the motion state of the terminal device based on the motion state data is not described in detail.

Wherein, when the system management module detects that the terminal device is in the long standby state, it may send a first message to the USB module to notify the USB module that the terminal device enters the long standby state.

S602. The USB module sleeps in response to detecting that the terminal device finishes executing services related to the external device.

In one embodiment, the processor of the external device can detect whether the transaction is completed. Exemplarily, if the service is for the terminal device to charge the external device, the processor of the external device can detect the power of the external device, and when the power is full (for example, the power of the external device reaches a preset power level), it can be determined that the service is completed. If the power of the external device is less than the preset power, the external device may determine that the terminal device has not completed the charging service.

Exemplarily, if the service is that the terminal device reads data in the external device, that is, the external device transmits data to the terminal device. It should be understood that data is composed of at least one data stream, and each data stream has a corresponding identifier, that is, an identifier of the data stream. Exemplarily, the data consists of three data streams, and the identifiers of the three data streams may be respectively: data stream 1, data stream 2, and data stream 3. The processor of the external device may detect the identifiers of the transmitted data streams, and when all the data streams are transmitted, the processor of the external device determines that the data transmission is completed, that is, the service is completed. If there is still an unsent data flow in the external device, the external device determines that the data transmission is not completed, that is, the service is not completed.

In this embodiment, when the processor of the external device detects that the service is completed, it sends a service completion signal to the USB module through the second function expansion pin and the first function expansion pin, so as to notify the USB module that the service is completed. Correspondingly, when the USB module receives a service completion signal from the processor of the external device through the first function expansion pin, it can be determined that the terminal device has finished executing services related to the external device, and then the USB module can go to sleep.

In one embodiment, the fact that the USB module is in the working state and not sleeping can be interpreted as: the USB module is locked. The sleep of the USB module can be understood as: the USB module releases the lock. Taking the Android system as an example, the wakelock in the Android system is a lock mechanism. If the application or any module in the terminal device holds this lock (that is, holds the lock), the system cannot enter sleep mode. In the embodiment of the present application, the lock held by the USB module can be understood as: the USB module holds the lock, and thus the AP cannot sleep. In one embodiment, the lock in the Android system can be timed out or not. The timed out lock will be automatically unlocked after the time elapses. If there is no application or module holding the lock or the timeout expires, the system will enter sleep mode. It should be understood that in the embodiment of the present application, there is no limitation on the lock timeout or no timeout. In the embodiment of the present application, the process of holding and releasing the lock will not be described in detail, and details can be referred to the current relevant description.

In one embodiment, the USB module itself can detect whether the transaction is completed. Exemplarily, if the service is that the terminal device writes data in the external device, that is, the terminal device transmits data to the external device. According to the relevant description above, the USB module can detect the identifiers of the transmitted data streams, and when all the data streams are transmitted, the USB module determines that the data transmission is completed, that is, the service is completed. If there is still an unsent data stream, the USB module determines that the data transmission is not completed, that is, the service is not completed.

In one embodiment, for example, if the service is that the terminal device reads data in the external device, that is, the external device transmits data to the terminal device, the USB module can detect whether there is a data stream from the external device within a preset period of time, If there is a data stream from the external device within the preset time period, the USB module can determine that the data transmission has not been completed; if there is no data stream from the external device within the preset time period, the USB module can determine that the data transmission is completed, that is, the business is completed .

In this embodiment, the USB module itself can detect whether the terminal device has finished executing the service related to the external device, and the USB module can sleep when detecting that the service is completed. In an embodiment, S602 may be replaced by: the USB module sleeps in response to detecting that the terminal device completes services related to the external device.

As mentioned above, when the terminal device is in the long standby state, when the terminal device finishes executing the business related to the external device, the USB module can release the lock and go to sleep, and then all the modules in the AP can perform sleep, and then the AP can Dormancy can reduce the power consumption of terminal equipment.

In the embodiment of this application, the USB module in the terminal device can detect whether the terminal device has finished executing the business related to the external device, or the external device can detect whether the terminal device has finished executing the business related to the external device, and then send the business to the USB module The completion signal is used to notify the USB module that the service is completed, and then the USB module can release the lock and go to sleep when detecting the completion of the service, so that the AP can also sleep, thereby reducing the power consumption of the terminal device.

In one embodiment, when the screen of the terminal device is turned on, the AP in the terminal device can exit the sleep state, and the USB module in the AP can switch from the sleep state to the working state, so that the terminal device can work normally. That is, after the above S602, it may also include:

S603, the system management module sends a second message to the USB module in response to detecting that the terminal device turns on or moves, and the second message is used to instruct the terminal device to exit the long standby state.

When the screen of the terminal device turns on or the terminal device moves, the terminal device exits the long standby state. In an embodiment, when the screen of the terminal device is off, the user may press a switch button on the terminal device to turn on the screen of the terminal device. Alternatively, the terminal device is in a static state, and when the user picks up the terminal device, the screen of the terminal device is turned on, and the method of turning on the terminal device is not limited in the embodiment of the present application.

The system management module may detect that the screen of the terminal device is on, and then in response to detecting that the screen of the terminal device is on, send a second message to the USB module to notify the USB module that the terminal device exits the long standby state. In an embodiment, the system management module may determine whether the screen of the terminal device is turned on based on a broadcast message from the system. Wherein, when the system management module receives a screen bright broadcast message from the system, it can determine that the terminal device bright screen.

Wherein, the system management module can obtain whether the terminal device is in a motion state or a static state based on motion state data collected by a gyroscope, an acceleration sensor, and the like. It should be understood that the movement of the terminal device means that the terminal device switches from a static state to a moving state. It should be understood that when the system management module detects that the terminal device is moving or the screen is turned on, the AP exits the dormancy state and enters the working state.

S604, the USB module switches from the dormant state to the working state.

After receiving the second message from the system management module, the USB module can switch from the dormant state to the working state. In other words, the USB module may perform locking in response to receiving the second message from the system management module.

In the embodiment of the present application, when the terminal device turns on the screen or moves, the AP in the terminal device can exit the dormancy state, the USB module in the AP can switch from the dormant state to the working state, and the terminal device can work normally.

In an embodiment, referring to FIG. 7 , the above S602 may be replaced with S602A-S604A.

S602A, the USB module detects whether the terminal device has finished performing services related to the external device; if yes, execute S604A, if not, execute S603A.

Referring to the relevant descriptions in the above embodiments, in one embodiment, the USB module can detect whether the terminal device has finished executing services related to the external device by itself. Alternatively, in an embodiment, the manner in which the USB module detects whether the terminal device finishes executing the service related to the external device may be: whether the USB module receives a signal from the processor of the external device that the service is completed. Wherein, if the USB module has received the service completion signal from the processor of the external device, it is determined that the service has been completed; if the USB module has not received the service completion signal from the processor of the external device, it is determined that the service is not completed.

S603A, the USB module is locked, and goes to sleep in response to detecting that the terminal device finishes executing services related to the external device.

When the service is not completed, the USB will hold a lock to ensure that the terminal device continues to perform services related to the external device. In this way, when the USB module detects that the terminal device has finished performing services related to the external device, it can release the lock and go to sleep. Wherein, the USB module detects that the terminal device finishes executing services related to the external device, and reference may be made to relevant descriptions in the foregoing embodiments.

S604A, go to sleep.

In one embodiment, "whether the execution is finished" can be replaced with "whether it is completed". Correspondingly, "executed" can be replaced with "completed", and "not executed" can be replaced with "not completed".

In the embodiment of the present application, when the USB module receives the first message from the system management module, it can detect whether the service is completed, and the USB module can release the lock after detecting that the service is completed, and go to sleep, thereby reducing the function of the terminal device. consumption.

Referring to FIG. 8 , in one embodiment, the system management module and the USB module can be set separately in the terminal device, or the system management module and the USB module can be integrated and set as one. This embodiment of the present application does not limit this, but no matter which For each setting form, the terminal device can perform the following steps:

S801. The terminal device detects that an external device is connected to the terminal device through the Type-C, and the terminal executes services related to the external device.

Services related to external devices may include: the terminal device charges the external device, or transmits data between the terminal device and the external device, where the data transmission between the terminal device and the external device may be: the terminal device sends data to the external device, or The external device sends data to the terminal device.

S802. The terminal device detects a motion state and a screen state of the terminal device.

In an embodiment, the motion state of the terminal device may include: a static state and a non-stationary state. It should be understood that the terminal device in the moving state in the foregoing embodiment may be understood as: the terminal device is in a non-stationary state.

S803. Based on the motion state and screen state of the terminal device, the terminal device controls the AP to sleep in response to detecting that the terminal device is in the long standby state and has finished executing services related to the external device.

In an embodiment, the terminal device controlling the AP to sleep may be: the terminal device controlling the AP to release all processes therein.

In one embodiment, the reason why the AP cannot sleep is that the USB function is still running, where the USB function may include but not limited to: transmitting data with an external device or charging the external device. Therefore, the above S803 can be replaced by: the terminal device, based on the motion state and screen state of the terminal device, in response to detecting that the terminal device is in the long standby state and has finished executing services related to the external device, stops executing the USB function and makes the AP sleep.

In one embodiment, referring to the foregoing embodiment, it is the USB module in the AP that executes the USB function. Therefore, stopping the execution of the USB function by the terminal device can be understood as: the terminal device controls the USB module to sleep.

S804. The terminal device controls the AP to exit dormancy in response to detecting the motion of the terminal device or turning on the screen of the terminal device.

Wherein, when the terminal device is in motion, the AP needs to obtain the motion state of the terminal device based on the motion state data of the terminal device, therefore, the AP exits dormancy. When the screen of the terminal device is on, the AP exits the sleep state, and the USB module can receive the second message from the system management module, and the USB module switches from the sleep state to the working state.
