Description

Method and device for switching on and off

technical field

The invention relates to the field of intelligent terminals, in particular to a method and device for turning on and off a machine.

Background technique

With the rapid development of the smart TV industry, the speed of switching on and off has attracted more and more attention from users. Generally, there are two switch modes for smart TVs. One is the shutdown triggered by the power on the main body of the smart TV, and all modules in the smart TV are powered off at this time; the other is triggered by pressing the power button on the remote control. Shut down, at this time, other modules in the smart TV except the memory and the main chip are powered off, and the memory and the main chip are in a low-power working mode.

The process of switching on and off triggered by the power button in the remote controller generally includes the following steps: When the user presses the power button on the remote controller to shut down, the kernel notifies all external applications after receiving the signal from the remote controller. When the device is powered off, the application program performs its own related processing according to the power-off status of the external device. After the processing of all the application programs is completed, the kernel saves the data in the memory; when the user presses the power button on the remote control to start the After the kernel receives the signal from the remote control, it detects the connected external device, restores the memory data, and sends the status information of the external device to the application program, and each application program performs corresponding processing according to the power-on status update of the external device.

In the process of triggering the power on and off through the power button in the remote controller, the inventor found at least the following problem in the prior art: no matter whether it is turned off or turned on, it is necessary to synchronize the status of the external device to the application program. Especially during the shutdown process, since the application program will modify the data in the memory according to the status change of the external device, in order to ensure the correctness of the memory data stored at the time of shutdown, it is necessary to wait for each application program to fully synchronize the changes in the external device before Save the data in the memory and complete the shutdown. This will cause the shutdown time to be prolonged as the number of applications related to external devices increases.

It should be noted that the execution subject of the method in Embodiment 1 and Embodiment 2 can be any smart terminal that can connect to external devices and has a fast power on/off mode, it can be a smart TV, a computer, or a smart terminal. speakers. The present invention is not limited thereto.

Embodiment one

An embodiment of the present invention provides a method for turning on and off a machine. As shown in Figure 1, including:

101. In the case of receiving the shutdown instruction, the kernel disconnects the connection with the external device, and interrupts the interaction with the application program.

It should be noted that the shutdown instruction is an instruction that instructs the kernel to control the power-off of other parts except the memory and the main chip.

Specifically, when the smart TV is in normal operation, the user presses the power button on the remote control, the remote control sends out a signal, the smart TV receives the signal from the remote control, and generates a shutdown command according to the current operating state of the smart TV, and the A shutdown command is sent to the kernel. The kernel controls power down of all modules except the memory and the main chip. Before the external device is powered off, send an external device removal message to the kernel. After receiving the external device removal message, the kernel notifies the driver module to delete the driver information corresponding to the external device, and interrupts the interaction with the application program, and does not synchronize the external device to the application program. Device removal status, so as to prevent the application from performing related processing according to the removal status of the external device.

It should be noted that in the case of fast shutdown, the kernel does not need to synchronize the external device state saved in the application program with the actual state of the external device perceived by the kernel. That is to say, although the kernel receives the external device removal message, it does not The information about the removal of the external device notifies the application program, and the relevant data of the external device saved by the application program after the quick shutdown is still stored according to the state of the external device inserted.

102. In the case of receiving the power-on instruction, the kernel starts and detects the hardware device, the kernel sends a reload message to the application program, and the application program updates the stored external device information according to the reload message.

Wherein, the reloading message includes the mounting path of the external device.

It should be noted that the external device information stored by the application refers to the relevant information of the external device obtained by the application program before shutdown and after the external device is plugged in. The information may include: external device identification, external device driver loading path, etc.

It should be noted that after the quick shutdown, the smart TV memory and the main chip work in a low-power state, and at this time the smart TV can still receive the signal sent by the remote control to trigger the start-up.

It should be noted that, when the smart TV is quickly shut down, the driver of the external device is uninstalled, and when the smart TV is quickly turned on, the driver of the external device is reloaded. When reloading the driver of the external device, the loading path is different from the loading path of the driver before shutdown, and the application program does not modify the relevant information of the external device during the fast shutdown, so after the fast boot, the application needs to update the external device saved by itself. Related Information.

Specifically, when the smart TV is in the standby state after being quickly shut down, the user presses the power button on the remote controller, the remote controller sends a signal, and the smart TV receives the signal sent by the remote controller, and generates a power-on command according to the current operating state of the smart TV , to send the power-on command to the kernel. The core controls the power-up of all modules. After the external device is powered on, it sends an external device connection message to the kernel. After the kernel receives the external device connection message, the kernel notifies the driver module to load the driver information corresponding to the external device. The driver module loads the driver program corresponding to the external device, and then the kernel notifies the application Update the information about the external device stored by the application.

Further, the reload message sent by the kernel to the application can be specifically:

The kernel sends a hardware reload event to the VOLD (full name in English: Volume Daemon, full name in Chinese: Volume Daemon) module; the VOLD module sends a hardware reconnection message to the MountService (full name in Chinese: Mount Service) module according to the hardware reload event; MountService The module sends a reload message to the application based on the hardware reconnect message.

It should be noted that the VOLD module is a daemon process of the storage class in the Android system, and is mainly responsible for the system's mounting/unmounting tasks for mass storage devices. The MountService module is a service class, which is equivalent to an intermediate bridge, responsible for receiving the messages of the Vold module and passing them to the upper application.

It should be noted that the kernel transmits the reload message to the application program through the VOLD module and the MountService module is only a method for the kernel to transmit the message to the application program, and the method for the kernel to transmit the reload message to the application program can also be any one of the prior art A method by which the kernel can pass messages to applications.

It should be noted that the interval between step 102 and step 103 may be several minutes, several hours, or several days, which is not limited in the present invention.

A method for switching on and off provided by an embodiment of the present invention includes: when receiving a shutdown command, the kernel disconnects the connection with the external device, and interrupts the interaction with the application program; when receiving the startup command, the kernel Start and detect the hardware device, the kernel sends a reload message to the application program, and the application program updates the stored external device information according to the reload message; the reload message includes the mounting path of the external device. In this way, by updating the triggering application to update the relevant information of the external device during the fast boot, the process of synchronizing the state of the external device between the kernel and the application during the shutdown process is broken, and finally, without increasing the boot steps, the process is simplified. The steps in the fast shutdown process speed up the shutdown time during fast shutdown.

Embodiment two

An embodiment of the present invention provides a method for turning on and off a machine. As shown in Figure 2, part a (including steps 201-203) in Figure 2 represents the interaction diagram between each module in the smart TV when it is turned off quickly, and part b (including steps 204-212) in Fig. 2 represents a quick start The interaction diagram between the modules in the smart TV, as shown in the reference figure, the method includes:

201. The kernel obtains a shutdown command, and controls all modules except the memory and the main chip to be powered off.

202. The external device is powered off and sends an external device removal message to the kernel, and the kernel receives the external device removal message.

203. The kernel notifies the driver module to delete the driver information corresponding to the external device, and the driver module uninstalls the driver program corresponding to the external device.

204. The kernel obtains a boot command, and the kernel controls all modules to be powered on and detects hardware devices.

205. After the external device is powered on, it sends an external device connection message to the kernel, and the kernel receives the external device connection message.

206. The kernel notifies the driver module to load the driver information corresponding to the external device, and the driver module loads the driver program corresponding to the external device.

207. The kernel sends a hardware reload event to the VOLD module.

208. The VOLD module sends a hardware reconnect message to the MountService module according to the hardware reload event.

209. The MountService module sends a reload message to all application programs associated with the external device registered in the MountService module according to the hardware reconnection message.

It should be noted that before the smart TV is quickly shut down, the application will register the external device associated with the application with the MountService module. Therefore, in step 209, the MountService module can determine which application programs have been associated with the external device.

210. The application program determines whether the external device information is stored.

211. In the case that the application program stores the external device information, the application program updates the stored external device information according to the reload message.

212. In the case that the application program does not store the information of the external device, the application program stores the reloading message.

It should be noted that if there is a new external device connected to the smart TV after the quick shutdown and before the quick startup, then after the quick startup, the corresponding application will register its associated new external device with the MountService module, but this At that time, the application program has not stored relevant information about the external device, so at this time, after receiving the reload message, the application program directly saves the relevant information carried in the reload message, and executes related logic with the application program.

In the method of switching on and off provided by the embodiment of the present invention, during the fast shutdown process, the kernel disconnects the connection with the external device, and does not synchronize the disconnected state of the external device to the application program; during the fast boot process, the kernel starts and detects the hardware device , the kernel sends a reload message to the application program, and the application program updates the stored external device information according to the reload message; the reload message includes the mounting path of the external device. In this way, by updating the triggering application to update the relevant information of the external device during the fast boot, the process of synchronizing the state of the external device between the kernel and the application during the shutdown process is broken, and finally, without increasing the boot steps, the process is simplified. The steps in the fast shutdown process speed up the shutdown time during fast shutdown.
