detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The invention proposes a method for synchronously launching a shared application by multiple devices.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a preferred embodiment of a method for synchronously launching a shared application by multiple devices in the present invention.

In the preferred embodiment of the method for multi-device synchronously opening shared applications proposed by the present invention, the method for multi-device synchronously opening shared applications includes:

Step S10, controlling the terminal to start the shared application;

In this embodiment, the control terminal may be a computer, a TV, other mobile phones, a PAD and other devices. In addition, when the control terminal starts the shared application, it needs to check whether the control terminal has opened the network connection module, if not, then open the network connection module to connect the control terminal to the designated LAN.

Step S20, the controlling terminal sends a corresponding command to start the shared application to the controlled terminal according to the network connection status of the controlled terminal;

In this embodiment, the controlled terminal may be a computer, a television, other mobile phones, a PAD, and other devices. The controlled terminal and the controlling terminal may be the same type of equipment or different types of equipment.

When the controlling terminal and the controlled terminal are connected through the network, the controlling terminal can send a command to open the shared application to the controlled terminal through the network; The connection method sends a command to open the shared application to the controlled terminal.

Step S30, the controlled terminal starts the shared application according to the received command to start the shared application.

When the controlled terminal opens the shared application, if the controlled terminal is not connected to the control terminal through the network, at this time, the controlled terminal also needs to open its network connection module to connect to the designated router. The control terminal and the control terminal can realize interaction through the network.

In the method for synchronously opening a shared application by multiple devices proposed by the present invention, when the controlling terminal opens the shared application, the controlling terminal sends a corresponding command to open the shared application to the controlled terminal according to the network connection status of the controlled terminal. When using the command to share the application, the controlled terminal starts the shared application, thereby avoiding the need for the user to open all the shared applications of the controlled terminal one by one to realize the interaction between multiple devices. Because the method for synchronously opening the shared application by multiple devices only needs to open the shared application of the control terminal, which greatly simplifies the user's operation process.

Specifically, referring to FIG. 2, step S20 specifically includes:

Step S21, judging whether the controlling terminal and the controlled terminal are connected to the same local area network;

If the controlled terminal is connected to the same local area network as the controlling terminal, execute step S22; if the controlled terminal is not connected to the same local area network as the controlling terminal, execute step S23.

Step S22, the controlling terminal sends an information broadcast to the controlled terminal through the network to enable the shared application;

Specifically, in this embodiment, the control terminal can choose to send an information broadcast for opening the shared application to all controlled terminals connected to the same local area network, or select several or a certain controlled terminal connected to the same local area network to send the open Information broadcast for shared applications.

Step S23, the controlling terminal sends an audio signal to the controlled terminal to control the controlled terminal to start the shared application.

The transmission of the audio signal does not depend on the network connection, so it is free from the limitation that the controlled terminal must be connected to the same local area network as the controlling terminal. Because some controlled terminals may not open their internal network connection modules, and the controlled terminal is not connected to the same local area network as the controlling terminal, at this time, the controlling terminal sends an audio signal to the controlled terminal to control the controlled terminal to open the The shared application mentioned above, after receiving the audio signal, the controlled terminal opens the shared application and connects to the designated LAN at the same time.

Specifically, the audio signal includes an audio signal representing the shared application information and an audio signal representing the local area network information.

In the present invention, in order not to affect the user, the frequency of the audio signal is set to be outside the range of 20-20000 Hz, which is not the range of human hearing. Each shared application is designed with an audio frequency bound to it, such as 20199Hz. At this time, 20199Hz represents the shared application. Because multiple shared applications may be installed on the controlled terminal, the audio signal needs to contain information about the shared application to be opened, so that the controlling terminal can correctly open the shared application.

In addition, the local area network automatically generates an audio bound to it according to its SSID. All controlled terminals will generate the same audio for the same LAN according to the same rules as long as the shared application is installed, such as 20033Hz. Because the controlled terminal may be connected to multiple local area networks, the controlled terminal can interact with the controlling terminal only when the controlled terminal is connected to the same local area network as the controlling terminal. Therefore, when the control terminal sends an audio signal, the control terminal needs to send out two pieces of audio with a frequency of 20199Hz and 20033Hz. When the controlled terminal receives these two pieces of audio, it can recognize the relevant information and open the sharing application.

In the method for synchronously opening a shared application by multiple devices proposed by the present invention, when the controlled terminal and the controlling terminal are connected to the same local area network, the controlling terminal sends an information broadcast to the controlled terminal through the network to open the shared application; when the controlled terminal does not communicate with the controlling terminal When connected to the same local area network, the controlling terminal sends an audio signal to the controlled terminal to control the controlled terminal to open the shared application, and the controlling terminal flexibly sends information to the controlled terminal according to the network connection status of the controlled terminal, even if the controlled terminal When there is no network connection with the control terminal, the controlled terminal can also obtain the command to start the shared application through the audio signal, thereby realizing the automatic start of the shared application without the network.

The present invention further proposes a system for synchronously launching shared applications by multiple devices.

The controlled terminal and the controlling terminal may be the same type of equipment or different types of equipment. In addition, when the control terminal starts the shared application, it needs to check whether the control terminal has opened the network connection module, if not, then open the network connection module to connect the control terminal to the designated LAN. In addition, the controlled terminal may be one or more devices.

When the controlling terminal and the controlled terminal are connected through the network, the controlling terminal can send a command to open the shared application to the controlled terminal through the network; The connection method sends a command to open the shared application to the controlled terminal. When the controlled terminal opens the shared application by starting the application module 11, if the controlled terminal is not connected to the control terminal through the network, at this moment, the controlled terminal also needs to open its network connection module to make it connected to the designated router. In this way, the controlled terminal and the controlling terminal can realize interaction through the network.

The transmission of the audio signal does not depend on the network connection, so it is free from the limitation that the controlled terminal must be connected to the same local area network as the controlling terminal. Because some controlled terminals may not open their internal network connection modules, and the controlled terminal is not connected to the same local area network as the controlling terminal, at this time, the controlling terminal sends an audio signal to the controlled terminal to control the controlled terminal to open the The shared application mentioned above, after receiving the audio signal, the controlled terminal opens the shared application and connects to the designated LAN at the same time. The audio signal includes application name information and LAN name information of the shared application to be opened.

Each shared application is designed with an audio frequency bound to it, such as 20199Hz. At this time, 20199Hz represents the shared application. Because multiple shared applications may be installed on the controlled terminal, the audio signal needs to contain information about the shared application to be opened, so that the controlling terminal can correctly open the shared application.

In addition, the fixed SSID of the local area network automatically generates an audio binding with it. All controlled terminals will generate the same audio for the same LAN according to the same rules as long as the shared application is installed, such as 20033Hz. Because the controlled terminal may be connected to multiple local area networks, the controlled terminal can interact with the controlling terminal only when the controlled terminal is connected to the same local area network as the controlling terminal. Therefore, when the control terminal sends an audio signal, the control terminal needs to send out two pieces of audio with a frequency of 20199Hz and 20033Hz. When the controlled terminal receives these two pieces of audio, it can recognize the relevant information and open the sharing application.

If the controlling terminal closes the shared application, it can send the command to close the application sharing through the network to the controlled terminal that can receive the command. If some controlled terminals have been disconnected from the network or have not received network information, the controlling terminal will send out an audio signal at this time. After receiving the audio signal, the controlled terminal checks whether it has closed the shared application. If the shared application has not been closed, the controlled terminal closes the shared application, thereby ending the sharing between the controlling terminal and the controlled terminal.

In the present invention, in order not to affect the normal work and study of the user, the frequency of the audio signal is set to be outside the range of 20-20000 Hz, which is not the range of human hearing. Each shared application is designed with an audio frequency bound to it, such as 20199Hz. At this time, 20199Hz represents the shared application. Because multiple shared applications may be installed on the controlled terminal, the audio signal needs to contain the information of the shared application to be opened, so that the controlling terminal can correctly open the shared application.

In addition, the local area network automatically generates an audio bound to it according to its SSID. All controlled terminals will generate the same audio for the same LAN according to the same rules as long as the shared application is installed, such as 20033Hz. Because the controlled terminal may be connected to multiple local area networks, the controlled terminal can interact with the controlling terminal only when the controlled terminal is connected to the same local area network as the controlling terminal. Therefore, when the control terminal sends an audio signal, the control terminal needs to send out two pieces of audio with a frequency of 20199Hz and 20033Hz. When the controlled terminal receives these two pieces of audio, it can recognize the relevant information and close the shared application.

In the method for synchronously closing shared applications of multiple devices proposed by the present invention, when the controlled terminal and the controlling terminal are connected to the same local area network, the controlling terminal sends an information broadcast to the controlled terminal through the network to close the shared application; when the controlled terminal does not communicate with the controlling terminal When connected to the same local area network, the controlling terminal sends an audio signal to the controlled terminal to control the controlled terminal to close the shared application, and the controlling terminal flexibly sends information to the controlled terminal according to the network connection status of the controlled terminal, even if the controlled terminal When there is no network connection with the controlling terminal, the controlled terminal can also obtain the command to close the shared application through the audio signal, thus realizing the automatic closing without network.
