Fig. 6 is a flowchart illustrating an embodiment of a method for reducing power consumption of a terminal device according to an embodiment of the present application. Referring to fig. 6, a method for reducing power consumption of a terminal device according to an embodiment of the present application includes:
s601, the system management module sends a first message to the USB module in response to the detection that the terminal device is in the long standby state, wherein the first message is used for indicating that the terminal device enters the long standby state.
It should be understood that the long standby state characterizes: the screen-off duration of the terminal equipment is greater than or equal to the preset duration, and the terminal equipment is in a static state. In one embodiment, the user may press a switch button on the terminal device to cause the terminal device to turn off the screen. Or, the user does not operate the touch screen of the terminal device for a long time (e.g., the first time), and the terminal device goes out of the screen. The system management module can detect that the terminal equipment is turned off, and then responds to the detection that the terminal is turned off, and starts to record the screen turning-off duration of the terminal equipment so as to obtain the screen turning-off duration of the terminal equipment. In one embodiment, the system management module may determine whether the end-point device is to be turned off based on a broadcast message from the system. When the system management module receives the screen-off broadcast message from the system, the screen-off of the terminal equipment is detected.
In an embodiment, the terminal device includes a gyroscope, an acceleration sensor, and the like, the gyroscope, the acceleration sensor, and the like may acquire motion state data of the terminal device and report the motion state data to the system management module, and the system management module may acquire the motion state of the terminal device based on the motion state data. When the screen-off time of the terminal equipment is greater than or equal to the preset time and the terminal equipment is in a static state, the system management module determines that the terminal equipment is in a long standby state. In this embodiment, details of how the system management module obtains the motion state of the terminal device based on the motion state data are not described.
The system management module may send a first message to the USB module to notify the USB module that the terminal device enters the long standby state in response to detecting that the terminal device is in the long standby state.
S602, the USB module responds to the detection that the terminal equipment finishes the execution of the service related to the external equipment, and carries out dormancy.
In one embodiment, the processor of the external device may detect whether the service is complete. For example, if the service charges the external device for the terminal device, the processor of the external device may 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), it may be determined that the service is completed. If the electric quantity of the external device is less than the preset electric quantity, the external device may determine that the terminal device has not completed the charging service.
Illustratively, if the service reads data in the external device for the terminal device, the external device transmits the data to the terminal device. It is to be understood that the data is composed of at least one data stream, each data stream having a corresponding identification, i.e. an identification of the data stream. Illustratively, the data consists of 3 data streams, and the three data streams may be identified as: data stream 1, data stream 2 and data stream 3. The processor of the external device may detect the identity of the transmitted data stream and when all data streams are transmitted, the processor of the external device determines that the data transmission is complete, i.e. the service is complete. If there is still unsent data stream in the external device, the external device determines that data transmission is not completed, i.e. service is not completed.
In this embodiment, when the processor of the external device detects that the service is completed, the processor sends a service completion signal to the USB module through the second function extension pin and the first function extension pin 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 extension pin, it may be determined that the terminal device has completed executing the service related to the external device, and the USB module may be in a sleep state.
In one embodiment, the USB module being in the working state without hibernation can be understood as: the USB module holds the lock. USB module hibernation can be understood as: the USB module releases the holding lock.

In the embodiment of the present application, the USB module holding lock may be understood as: the USB module holds the lock and the AP cannot sleep. In one embodiment, the lock in the android system may or may not be timed out, the timed out lock will automatically unlock after the time has elapsed, and if no application or module holds the lock or times out, the system will go to sleep. It should be understood that the embodiments of the present application are not limited to the lock timing out or the absence of timing out. In the embodiment of the present application, the process of holding and releasing the lock is not described in detail, and reference may be specifically made to the related description.
In one embodiment, the USB module itself may detect whether the service is complete. Illustratively, 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 above description, the USB module may detect the identifier of the transmitted data stream, and when all data streams are transmitted, the USB module determines that the data transmission is completed, i.e. the service is completed. If there is still unsent data stream, the USB module determines that data transmission is not completed, i.e., the service is not completed.
In an 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 may detect whether a data stream from the external device exists within a preset time period, if the data stream from the external device exists within the preset time period, the USB module may determine that data transmission is not completed, and if the data stream from the external device does not exist within the preset time period, the USB module may determine that data transmission is completed, that is, the service is completed.
In this embodiment, the USB module may detect whether the terminal device has executed a service related to the external device, and the USB module may sleep when detecting that the service is completed. In one embodiment, S602 may be replaced with: and the USB module responds to the detection that the terminal equipment completes the service related to the external equipment and carries out dormancy.
As described above, when the terminal device is in the long standby state and the terminal device executes the service related to the external device, the USB module may release the holding lock to perform the sleep, and then all the modules in the AP may execute the sleep, and then the AP may sleep, which may reduce the power consumption of the terminal device.
In the embodiment of the application, the USB module in the terminal device can detect whether the terminal device has executed the service related to the external device, or the external device can detect whether the terminal device has executed the service related to the external device, and then send a signal of service completion to the USB module to notify that the service of the USB module is completed, and then the USB module can release the holding lock when detecting that the service is completed, so as to sleep, so that the AP can also sleep, and further, the power consumption of the terminal device is reduced.
In an embodiment, when the terminal device is turned on, the AP in the terminal device may exit from the sleep mode, and the USB module in the AP may be switched from the sleep mode to the operating mode, so that the terminal device operates normally. Namely, the above S602 may further include:

And the terminal equipment is on the screen or moves, and the terminal equipment exits the long standby state. In one embodiment, when the terminal device is off, the user can press a switch key on the terminal device, so that the terminal device is on. Or the terminal device is in a static state, and when the user picks up the terminal device, the terminal device lights up the screen.
The system management module can detect that the terminal equipment is on screen, and then sends a second message to the USB module in response to the detection that the terminal equipment is on screen so as to inform the USB module that the terminal equipment exits the long standby state. In one embodiment, the system management module may determine whether the terminal device is on screen based on a broadcast message from the system. When the system management module receives the bright screen broadcast message from the system, it can be determined that the terminal device is bright.
The system management module can acquire the motion state or the static state of the terminal device based on motion state data acquired by a gyroscope, an acceleration sensor and the like. It should be understood that terminal device movement refers to: and the terminal equipment is switched 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 is on screen, the AP exits from sleep and enters a working state.
S604, the USB module is switched from the dormant state to the working state.
The USB module receives a second message from the system management module and can switch from the dormant state to the working state. In other words, the USB module may perform lock holding in response to receiving the second message from the system management module.
In the embodiment of the application, when the terminal equipment is on a screen or moves, the AP in the terminal equipment can quit from the sleep state, the USB module in the AP can be switched to the working state from the sleep state, and the terminal equipment can work normally.

If the USB module has received the signal indicating that the service from the processor of the external device is completed, it is determined that the service is completed, and if the USB module has not received the signal indicating that the service from the processor of the external device is completed, it is determined that the service is not completed.
S603A, the USB module is locked, and the terminal equipment is responded to detect that the terminal equipment completes the service related to the external equipment, and the dormancy is carried out.
When the service is not completed, the USB can hold the lock to ensure that the terminal equipment continues to execute the service related to the external equipment. Therefore, when the USB module detects that the terminal equipment finishes executing the service related to the external equipment, the holding lock can be released to carry out dormancy. The USB module detects that the terminal device has executed the service related to the external device, and reference may be made to the relevant description of the above embodiment.
