After receiving a second screen projection request through the first system, the display device firstly sends the second screen projection request to the second system through the first system according to the routing configuration recorded in the first system, wherein the routing configuration is used for realizing communication between the first system and the second system through a network card; and then sequentially sending a second message to the screen projection equipment through the second system and the first system, wherein the second message is used for indicating to send screen projection data to the second system.

Wherein the second system can send the second message to the first system, and then the first system sends the second message to the screen projection device.

And after receiving the second message, the screen projection equipment sends the screen projection data on the first equipment to the second system according to the network address of the second system, and the first equipment is connected with the screen projection equipment. For example, the screen projection device is inserted into the first device through a USB (universal serial bus) interface.

Correspondingly, the display equipment receives screen projection data through the first system; and sending the screen projection data to the second system by the first system according to the routing configuration recorded in the first system.

The routing configuration includes network routing information between the first system and the other systems, that is, which network card the first system sends the screen projection data to the other systems. The routing configuration is obtained by pre-configuration according to the system and the network card of the display device.

Certainly, after the display device receives the first screen projection request, if the user does not select the second system or selects the first system, the first system replies a third message, where the third message is used to indicate to send screen projection data to the first system, and the third message may carry an identifier of the first system.

And after receiving the third message, the screen projection equipment sends screen projection data to the first system according to the network address of the first system.

The display equipment receives the screen projection data through the first system and displays an interface corresponding to the screen projection data in the first system.

It should be noted that, before the screen projection device sends the first screen projection request to the display device, a communication link between the screen projection device and the display device needs to be established according to one of the at least two pieces of network information. The communication link is realized through a network card corresponding to the first network information, and the communication link is used for communication between the display device and the screen projection device, and comprises a first screen projection request, a second screen projection request and screen projection data which are sent to the display device by the screen projection device, and a first message and a second message which are sent to the screen projection device by the display device.

The network information respectively corresponding to the at least two network cards of the display device and the network addresses of the systems of the display device are collectively referred to as information of the display device, and when the screen projection device is connected with the display device, the information is written into the screen projection device together. In this way, after the user selects the second system, the network address of each system is included in the screen-shot system, that is, the network address of the second system is included. Therefore, the user does not need to re-insert the screen projection equipment into the display equipment so as to write the network address of the second system and the network information of the network card into the screen projection system, and the operation complexity of the user is reduced.

Optionally, before the screen projection device sends the first screen projection request to the display device, the screen projection device may further obtain a default network address from network addresses of systems of the display device, which are locally stored; and generating a first screen projection request according to the default network address.

Wherein the default network address may be a specially marked network address.

Of course, the default network address can be flexibly set by the user. Specifically, the screen projection equipment receives a default system switching instruction; and responding to a default system switching instruction, and switching the default network address among the network addresses of the systems by the screen projection equipment.

In practical applications, a flag may be set to the network address of one of the systems stored in the screen projection device to indicate that the network address of the system is the default network address, and the system is the first system. The user can modify the flag for the purpose of switching the default network address.

The first system may be a default system, and a plurality of network cards exist in the first system to realize communication between the first system and other systems and communication between the first system and the screen projection device. Since the display device in the embodiment of the present application only sets the network card in the first device, each network card is single.

Fig. 4 schematically illustrates a system structure of a display device provided in an embodiment of the present application. Referring to fig. 4, the display device includes both an android system and a Windows system. Wherein, tall and erect system is first system. Of course, in practical applications, the Windows system may also be used as the first system. In the embodiment of the present application, one system may be selected from a plurality of systems in advance as a first system, and a multi-network card is implemented in the system to process a plurality of network signals.

Referring to fig. 4, three kinds of network cards are implemented in the android system: an AP (access point) network card, a WLAN (wireless local area network) network card, and an ETH (Ethernet) network card, wherein the ETH includes ETH0 and ETH 1. Of course, the number of the ethernet network cards may be set according to an actual application scenario, and the embodiment of the present application does not limit the number of the ethernet network cards. Therefore, the screen projection device can be communicated with the android system through any network card, and the android system is communicated with the Windows system through another network card. For example, the screen projection device may access a hotspot of the display device, so that the screen projection device may communicate with the android system through the AP network card, and the android system may communicate with the Windows system through the ETH 1. Since the display device in fig. 4 is provided with only an AP in the android system, the display device in fig. 4 may be referred to as a single hot spot device.

As can be seen from fig. 4, data between the android system and the Windows system needs to be converted by two controllers C1 and C2. When the android system sends data to the Windows system, the data needs to be converted from a USB signal into a network signal through the controller C1, then the network signal needs to be converted into a USB signal through a control signal, and finally the USB signal is sent to the Windows system.

It can be seen that the display device and the screen projection device can form a multi-system screen projection processing system.

Fig. 5 illustrates an interaction diagram between a screen projection device and a display device provided by an embodiment of the present application. Referring to fig. 5, it can be seen that the interaction process between the screen projection device and the display device may include the following steps:

and S1, the screen projection device sends a first screen projection request to the display device, and the first screen projection request is used for requesting screen projection to the first system.

And S2, after the display device receives the first screen projection request, if the user selects the second system, the display device sends a first message to the screen projection device to indicate screen projection to the second system.

And S3, after receiving the first message, the screen projection device sends a second screen projection request to the display device, wherein the second screen projection request is used for requesting screen projection to a second system.

And S4, after receiving the second screen projection request, the display device sends a second message to the screen projection device, wherein the second message is used for indicating that screen projection data are sent to the second system.

And S5, after receiving the second message, the screen projection device sends screen projection data to the display device.
