Description

Data sharing method and display device

Technical Field

The present invention relates to the field of display devices, and in particular, to a data sharing method and a display device.

Background

The network cards configured by the display device may generally include a wired network card and a wireless network card, and when the display device accesses to a network, network addresses for network positioning, that is, IP (Internet Protocol Address, internet protocol) addresses, are only allocated and acquired for the network cards of the display device based on a network protocol, so as to realize network communication between the display device and other devices in the network.

After the display device is accessed to the network, the network can be shared with external devices. After different external devices all obtain the network shared by the display devices, the external devices can be further set to obtain routes between network ports of the shared network, so that network packets can be mutually transmitted between the different external devices, and data sharing between the different external devices is realized. At present, a script is usually used, and different external devices are set to acquire routes among network ports of a shared network. The principle of setting the route through the script is to set the command line row by using the existing debugging program of the Android (Android) platform, so that the route is actually set by using fixed code logic.

However, by setting the route between the network ports of the shared network by using the above manner, the link is unstable, and if the Android system of the display device starts the enforcement mode of the selinux (file access security policy) authority, the scenario execution may be limited, which may result in failure in setting the route between the network ports of the shared network by using the different external devices, and further result in failure in data sharing.

As shown in fig. 4, the system of the display device is divided into three layers, an application layer, a middleware layer, and a hardware layer, from top to bottom.

For clarity of explanation of the technical solutions of the present application, firstly, explanation will be made on the terms designed in the present application:

a network card, also known as a network adapter or network interface card (NIC, network Interface Card), is a device that connects a computer or display device to a local area network. The network card is inserted in an expansion slot of a computer, display equipment or a server, and exchanges data with a network and shares resources through a network cable. In addition, after the network card is installed, the protocol is often required to be configured. The network card can package the data of the computer into frames and send the data to a network through a network cable (electromagnetic wave for a wireless network); the network card can also receive frames transmitted by other devices on the network, recombine the frames into data and send the data to the device where the network card is located. The network cards are further classified into wired network cards and Wireless network cards, i.e., LAN (Local Area Network ) network cards and WLAN (Wireless LAN) network cards. The LAN network card may be provided with a wired network by the wired communication module, so that the device accesses the local area network in a wired manner. The WLAN network card may be provided with a wireless network by the wireless communication module so that the device accesses the local area network in a wireless manner.

Network nodes, network nodes and routers are key components of the internet implementation that enable the transmission and routing of data in the internet. The network node may be a network device in the internet, which may be a network device such as a computer, a server, a router, a switch, or a port on the network device for transmitting or receiving a data packet. The network nodes may identify and communicate with each other via the internet protocol, each network node having a unique IP address for identifying its location in the internet. The wired network node in the embodiment of the application is a network port needing wired connection, and after the device is connected with the network port in a wired manner, network signals can be obtained from the network port, so that the purpose of accessing the network is achieved.

A USB (Universal Serial BUS ) network card, i.e. a network card with a USB interface.

The hotspot network node, i.e. the wireless AP (Access Point), can implement a network sharing function by the device through the wireless AP. The network sharing function is that a device with communication capability converts a received GPRS (General Packet Radio Service, general packet radio service technology), 3G (Third Generation mobile communication) or 4G (fourth Generation mobile communication) signal into a Wi-Fi signal, so that other devices with WiFi modules can also use the network of the display device to surf the internet, and the device sharing the network is equivalent to a wireless AP. The device needs to turn on the WLAN hotspot function to enable network sharing.

The routing refers to path information for guiding the sending of the IP message, namely path information for guiding how to send the data message (data packet) between the nodes. Determining path information requires knowledge of the addresses of the ports, so two conditions for creating routes between nodes (ports) are: the port is in an open state and the port is assigned an IP address. The router is divided into a dynamic router and a static router, wherein the dynamic router means that the router can automatically check and record own routing tables and can automatically and dynamically adjust according to the change of actual conditions; static routing is fixed and does not change with changes in the actual network state.

In some embodiments, the terminal device may also share the network to external devices after accessing the network. Different external devices access the same local area network, and the external devices can be set to acquire the route between the network ports of the shared network, so that network data packets can be mutually transmitted between the external devices, and data sharing between different external devices is realized.

For example, as shown in fig. 5, the display device 200 may share a network connected to itself to the first device 500 through a wired network port, that is, after the first device 500 uses the wired network and the display device 200 to connect, the first device acquires a network signal from the display device 200 and accesses the same local area network. The display device 200 may also send out a hotspot, and the second device 500 may access the same lan after being connected to the hotspot to obtain a network signal. After the first device 500 and the second device 600 access the same lan, a route between a network port connected to the first device 500 and a network connected to the second device 600 may be set, so that network data packets may be transmitted between the first device 500 and the second device 600, so as to implement data sharing between the first device 500 and the second device 600.

The route between the portal to which the first device 500 is connected and the portal to which the second device is connected may be set using a script form. The principle of setting the route by using the script is to set command lines line by using the existing debugging program of the Android platform (the system of the display device is an Android system). When the command line is set, the information of the link needs to be fully known, and gradual setting is needed according to the fully known information of the link, so that the script is actually used for setting the route, a large amount of fixed code logic is needed, if one path of the link needed for setting the route is not considered to be comprehensive, the route setting is failed, and further the data sharing is failed.

In addition, the nature of the script is a combination of commands, the actual requirement of the start script depends on the logic of the Framework layer, after the Framework layer receives the broadcast of the network connection, the Framework layer needs to start the service registered by the system, and the shell script (programmed script) is executed through the service, so that the flow of executing the script is complex. If the user frequently operates the network to disconnect, the user needs to frequently register the service, and too frequent registration may cause failure of service registration, so that the shell script cannot be executed, further cause failure of route setting, and finally cause failure of data sharing.

In view of the above, some embodiments of the present application provide a display apparatus 200. In order to facilitate understanding of the technical solutions in some embodiments of the present application, the following details of each step are described with reference to some specific embodiments and the accompanying drawings. Fig. 6 is a schematic diagram of a data sharing system framework according to some embodiments of the present application. Fig. 7 is a flowchart illustrating a method for executing data sharing by the display device 200.

As shown in fig. 6, the data sharing system according to the embodiment of the present application mainly includes: a display device 200, a first device 500 and a second device 600. The display device 200 includes at least one network card capable of networking, a wired network node eth1, and a hotspot network node AP0. The networking card is connected with a communication module, and the communication module can provide a network to the display device 200 through the networking card. The first device 500 is connected to a wired network node eth1, through which wired network node eth1 the first device 500 can access the network. If the display device 200 is connected to the network, the network may also be provided to the at least one second device 600 through the hotspot network node AP0, i.e. the at least one second device 600 may be connected to the network through the hotspot network node AP0. For the second device 600, the display device 200 is a wireless AP, and the hotspot network node AP0 is an AP node. The wired network node eth1, the hot spot network node AP0 and the networkable network card are all arranged on a SOC (System-on-a-Chip) Chip.

Based on the schematic diagram of the data sharing system framework shown in fig. 6, as shown in fig. 7, the data sharing method executed by the display device 200 provided in the embodiment of the present application includes the following steps:

step S100, if it is detected that the communication module provides a first network to the network card capable of being networked, and at least one second device 600 is connected to the hotspot network node AP0, the first network is provided to the second device 600 through the hotspot network node AP0, so that the second device 600 accesses the first network.

The network card capable of being networked in the embodiment of the application can be a wired network card or a wireless network card. If the networkable network card is a wired network card, the wired communication module provides a network to the display device 200 through the wired network card, that is, the system of the display device 200 may access the wired network provided by the wired communication module through the wired network card. If the networkable network card is a wireless network card, the wireless communication module provides a network to the display device 200 through the wireless network card, that is, the system of the display device 200 can access the wireless network provided by the wireless communication module through the wireless network card.

The communication module can be a Zigbee wireless communication device (Zigbee is a low power consumption local area network protocol based on the ieee802.15.4 standard, zigbee technology is a wireless communication technology with short distance and low power consumption), a 4G or 5G communication module, a wireless WiFi module, and the like, and these communication modules can establish communication with a base station, and then provide a network for the display device. If the networking network card is a wireless network card, the communication module for providing a network for the wireless network card is a wireless communication module, for example, the communication module can be a wireless WiFi module; if the networkable network card is a wired network card, the communication module providing the network for the wired network card is a wired communication module, for example, the network card may be a routing device with a communication networking function connected by a physical medium (such as a network cable, etc.), and the routing device may be regarded as the wired communication module.

The Android system of the display device 200 may create at least one listening service for listening to the network card capable of networking, where the listening service is used to determine whether the communication module provides the first network to the network card capable of networking. If the communication module provides the first network to the networkable network card, the networkable network card may receive the data packet from the communication module, so the listening service may listen to whether the networkable network card receives the data packet transmitted from the communication module to determine whether the communication module provides the first network to the networkable network card. If the network card acquires the data packet from the communication module, a monitoring event can be generated, and the controller judges that the communication module provides a first network for the network card according to the monitoring event. If the display device 200 includes a plurality of networking-capable network cards, a network card identification of the networking-capable network card may be marked on the generated listening event, and the controller may determine which of the networking-capable network cards is provided with the first network according to the network card identification.

For example, the SOC chip of the display device 200 is configured with a networkable network card a, a networkable network card B, and a networkable network card C, and if the communication module provides the networkable network card a with the first network, the listening service may mark the network card identifier a of the networkable network card a on the listening event when generating the listening event. After receiving the monitoring event, the controller can judge that the communication module provides the first network for the network card A capable of being connected with the network according to the network card identifier A carried by the monitoring event. In this way, the route between the network card which is already connected to the network and the first network node can be set accurately. If the communication module provides the first network to the networkable network card a and the networkable network card B, the listening service may generate two listening events: the network card monitoring system comprises a first monitoring event and a second monitoring event, wherein the first monitoring event carries a network card identifier A of a network card A capable of being connected with the network, and the second monitoring event carries a network card identifier B of a network card B capable of being connected with the network. The controller may determine, according to the first listening event and the second listening event, that the communication module provides the first network to the networkable network card a and the networkable network card B.

When the communication module provides the first network for the network card capable of being connected with the network, the system can also configure a service for acquiring the IP for the network card capable of being connected with the network, and the service for acquiring the IP firstly inquires whether the first network node of the network card capable of being connected with the network exists or not, namely the first network node of the network card capable of being connected with the network is in an up state (normal working state). If the first network node of the networking network card exists, the first network node corresponding to the networking network card is ready, then the networking network card is started, the IP is acquired through the dynamic host configuration protocol client, and the dynamic host configuration protocol server receives a request and sends the IP to the networking network card. After the networking network card acquires the IP, the information such as the IP is written into the networking network card, and the process that the communication module provides the first network for the networking network card is completed at the moment.

Upon detecting that the communication module provides the first network to the networkable network card, it is further necessary to continue to determine whether at least one second device 600 is connected to the hotspot network node AP0. If the communication module provides the first network to the networkable network card, the display device 200 accesses the first network at this time, and if the display device 200 turns on the hotspot function (and is set to the AP mode instead of the STA (station) mode), the first network may also be shared to the at least one second device 600 through the hotspot function. The second device refers to a device connected to the hotspot network node AP0, i.e. a device connected to the hotspot on which the display device 200 is turned on at this time.

The manner in which the second device 600 connects to the hotspot of the display device 200 may be: after the display device 200 turns on the hotspot function, the display device 200 may convert the network signal of the connected first network into a Wi-Fi signal and then send the Wi-Fi signal. After the second device 600 searches the Wi-Fi signal shared by the display device 200 through the hotspot, the second device 600 may access the hotspot Wi-Fi by inputting the hotspot name and the hotspot password of the hotspot Wi-Fi on the user interface of the second device 600, so as to achieve the purpose that the second device 600 accesses the first network through the hotspot network node AP0.

The process of configuring the IP address for the second device 600 may further include: when the hot spot network node AP0 is started, a third gateway address is configured for the hot spot network node AP 0; when the second device 600 is connected to the hotspot network node AP0, a fourth gateway address is configured for the second device 600 according to the third gateway address, so that the second device 600 accesses the first network using the fourth gateway address.

After the display device 200 starts the hotspot function, an IP address (third gateway address) may be configured for the hotspot network node AP0, and at this time, a route between the hotspot network node AP0 and the networkable network card is actually required to be created according to the IP address of the hotspot network node AP0 and the IP address of the networkable network card, so that the networkable network card may transmit the network signal of the first network to the hotspot network node AP0, and then the hotspot network node AP0 converts the network signal of the first network into a Wi-Fi signal and then outputs the Wi-Fi signal. The second device 600 can then connect to the hotspot network node AP0 using the hotspot name and the hotspot password after searching that the Wi-Fi signal is.

After the hotspot network node AP0 is allocated to the IP address, and the second device 600 is connected to the hotspot network node AP0 by using the hotspot name and the hotspot password, the system configures an IP address (a fourth gateway address) for the second device (a wireless network card of the second device) according to the IP address of the hotspot network node AP0, where the fourth gateway address and the third gateway address are located in the same network segment, so that the second device 600 can access the first network (obtain a network signal of the first network) according to the fourth gateway address.

Step S200, creating a first route between the networkable network card and the wired network node eth1, and providing the first network to the first device 500 through the first route, so that the first device 500 accesses the first network.

Step S100 is an implementation step of accessing the first device 500 to the first network, and step S200 is an implementation step of accessing the second device to the first network. Since the first device 500 is connected to the wired network node eth1, it is necessary to create a first route between the networkable network card and the wired network node eth1, to enable network packet transmission between the networkable network card and the wired network node eth1 through the first route, and then to enable the first device 500 to be connected to the first network.

The procedure for creating the first route between the networkable network card and the wired network node eth1 may be: firstly, creating a routing file; importing a route module for creating a route into a route file; introducing the name and the IP address of the node to be linked into the routing module, namely introducing the name and the IP address of the network card capable of networking and the wired network node eth1 to be routed; creating a routing path according to the name and the IP address of the network card capable of being connected with the network and the wired network node eth 1; creating a route object according to the created route path; the created routing object is exported to external use. After the first route between the networkable network card and the wired network node eth1 is created, as shown in the route diagram of fig. 8, the networkable network card may provide the network signal of the first network to the wired network node eth1 through the first route, so that the wired network node eth1 accesses the first network.

Therefore, before creating the first route, it is necessary to acquire the IP addresses of the networkable network card and the wired network node eth1, and then create the first route between the networkable network card and the wired network node eth1 according to the IP addresses of the networkable network card and the wired network node eth 1. The system can also configure an IP obtaining service for the network card capable of being connected, when the communication module provides the first network for the network card capable of being connected, the network card capable of being connected is started, then the IP is obtained through the dynamic host configuration protocol client, and the dynamic host configuration protocol server receives a request and sends the IP to the network card capable of being connected. After the networking network card acquires the IP, the information such as the IP is written into the networking network card, at the moment, the networking network card records a usable IP address, and a route between the networking network card and other nodes can be established by utilizing the IP address.

The IP address acquisition procedure of the wired network node eth1 may be: configuring a first gateway address for the wired network node; if a path is detected to be established between the wired network node and the first device 500, a second gateway address is configured for the first device 500 according to the first gateway address such that data packets are transmitted between the first device 500 and the wired network node using the path according to the first gateway address and the second gateway address.

In some embodiments, as shown in fig. 15, the wired network node eth1 may be a USB network card, the path includes the USB network card, a USB-to-LAN network card (ethernet controller ) and a LAN-to-USB network card (ethernet controller ), the USB network card is connected to the USB-to-LAN network card, the USB-to-LAN network card is connected to the LAN-to-USB network card, and the LAN-to-USB network card is connected to the first device, wherein the USB network card may convert a network signal into a USB signal, the USB-to-LAN network card may convert the USB signal into a network signal, and the LAN-to-USB network card may convert the network signal into a USB signal. The specific implementation process of the signal transmission is that the wired network node eth1 receives a first network signal, converts the first network signal into a first USB signal, and then transmits the first USB signal to the USB-to-LAN network card. And after the USB-to-LAN card converts the first USB signal into the second network signal, the second network signal is transmitted to the LAN-to-USB card. The LAN-to-USB network card converts the second network signal into a second USB signal, and then transmits the second USB signal to the first device 500. In this way a wired connection between the wired network node eth1 and the wired network card on the first device 500 can be achieved.

The embodiment of the application is based on Android native logic, and the network line identification function of the wired network node eth1 is filtered, namely if a wired network line is inserted into a port corresponding to the wired network node eth1, the insertion of the wired network line is not identified, and the wired network node eth1 is used as a node capable of sharing a network. After the Android system of the display device 200 is started, network sharing is started, then an IPserver is started, at this time, the Android system enters an IPserver state, and configuration and starting of a DHCP (Dynamic Host Configuration Protocol ) server are started. The DHCP is an application layer protocol, and when the system IP address of the display device 200 is set to be in a dynamic acquisition mode, the DHCP server allocates an IP to the client according to the DHCP protocol, so that the display device 200 can access the network using the allocated IP.

After the server allocates an IP address to the wired network node eth1 of the display device 200 based on DHCP, i.e., allocates the first gateway address, if a path is established between the detected first device 500 and the wired network node eth1 (when the first device 500 is connected to the wired network node eth1 through a network line, a path is established between the first device 500 and the wired network node eth 1), a flow of requesting the IP address may be started according to a flow of normally inserting the network line. Since the display device 200 shares a network to the first device 500 through the wired network node eth1, the IP address (second gateway address) and the IP address of eth1 that can be acquired by the first device 500 (wired network card of the first device 500) are IP addresses in one network. In this way, the cable network card and the cable network node eth1 of the first device 500 may perform transmission of the data packet.

After the networkable network card acquires the IP address and the wired network node eth1 acquires the allocated IP address, a first route between the networkable network card and the wired network node eth1 can be created. The networkable network card may then send a network signal via the first route to the first device 500 having established a path with the wired network node eth1, i.e. to enable the first device 500 to access the first network.

Step S300, creating a second route between the wired network node eth1 and the hot spot network node AP0, so that the first device 500 transmits a data packet to the second device 600 based on the second route and the first network, or the second device 600 transmits a data packet to the first device 500 based on the second route and the first network.

Based on step S100 and step S200, after the first device and the second device access to the first network, a second route between the wired network node eth1 and the hotspot network node AP0 needs to be created, so that after the first device 500 and the second device 600 access to the same local area network, based on the created second route, data transmission between the first device 500 and the second device 600 can be performed, and data sharing is achieved. As shown in the routing diagram of fig. 8, after the first device 500 and the second device 600 access the same lan, the first device 500 may transmit the network data packet to the second device 600 via the routing path of the second device 600 of the hotspot network node AP 0-the wired network node eth1, and the second device 600 may transmit the network data packet to the first device 500 via the routing path of the first device 500 of the hotspot network node AP 0-the wired network node eth1, so as to realize data sharing between the first device 500 and the second device 600.

The procedure of creating the second route between the wired network node eth1 and the hotspot network node AP0 may comprise: firstly, creating a routing file; importing a route module for creating a route into a route file; introducing names and IP addresses of nodes to be linked into a routing module, namely, introducing names and IP addresses of a wired network node eth1 and a hot spot network node AP0 to be routed; creating a routing path according to the names and the IP addresses of the hot-spot network node AP0 and the wired network node eth 1; creating a route object according to the created route path; the created routing object is exported to external use. Therefore, before creating the second route, it is also necessary to acquire the IP addresses of the hot spot network node AP0 and the wired network node eth1, and then create the first route between the hot spot network node AP0 and the wired network node eth1 according to the IP addresses of the hot spot network node AP0 and the wired network node eth 1.

As can be seen from the above technical solutions, in the data sharing method provided by the present application, the display device 200 includes at least one network card capable of being networked, and the communication module can provide a network for the display device through the network card capable of being networked; the first device 500 may connect to the network through the wired network node eth 1. The hot spot network node AP0, and the display apparatus 200 may provide a network to at least one second apparatus 600 through the hot spot network node AP 0. If it is detected that the communication module provides the first network to the networkable network card and that at least one second device 600 is connected to the hotspot network node AP0, the first network is provided to the second device 600 by the hotspot network node AP0, the second device 600 may access the first network. At this point a first route between the networkable network card and the wired network node eth1 is created and the first network is provided to the first device 500 via the first route, which first device 500 can then access. A second route is created between the wired network node eth1 and the hot spot network node AP0, and data packets can be transmitted between the first device 500 and the second device 600 based on the first network and the second route. According to the method and the device, the Android native packaged nodes are utilized, the routes between the nodes are set, so that the set route links are more stable, the situation that the script execution is limited to cause the route setting failure can be avoided, the route setting success rate is improved, and the success rate of data sharing among different devices is further improved.

In some embodiments, as shown in fig. 9, the display device 200 includes two networkable network cards, and the two networkable network cards are a wired network card and a wireless network card respectively, where the wired network card is connected to a wired communication module, and the wireless network card is connected to a wireless communication module. The networking situation of the entire data sharing system therefore exists in several ways:

as shown in the data sharing system frame diagram of fig. 10, if only the wireless communication module provides the wireless network to the wireless network card WLAN0, the system only detects that the wireless communication module provides the wireless network card WLAN0 with the network, and only the wireless network card WLAN0 up (normal operating state) is provided, the wireless network provided by the wireless communication module to the wireless network card WLAN0 is determined as the first network, the wireless network can be provided to the second device 600 through the hotspot network node AP0, and the second device 600 accesses the wireless network. Then a first route between the wireless network card WLAN0 and the wired network node eth1 is created, so that the wireless network card WLAN0 may provide the first device 500 with the wireless network through the first route, enabling the first device 500 and the second device 600 to access the same local area network. That is, the current wireless network card WLAN0 provides a network to the first device 500 through the wired network node eth1, and provides a network to the second device 600 through the hot spot network node AP 0.

As shown in the data sharing system frame diagram of fig. 11, if the wireless communication module provides the wireless network to the wireless network card WLAN0 and the wired communication module provides the wired network to the wired network card eth0, the system will detect that the wireless network card WLAN0 and the wired network card eth0 access the network at the same time, and at this time, the wireless network card WLAN0 and the wired network card eth0 are up at the same time. Since the wired network is generally more stable than the wireless network, only the wired network provided by the wired communication module to the wired network card eth0 is determined as the first network, which may be provided to the second device 600 through the hotspot network node AP0, and the second device 600 accesses the wired network. A first route between the wired network card eth0 and the wired network node eth1 is then created, so that the wired network card eth0 can provide the first device 500 with the wired network through the wired network node eth 1. The first device 500 and the second device 600 are enabled to access the same local area network. I.e. the current wired network card eth0 provides the first device 500 with a network via the wired network node eth1 and the second device 600 via the hot spot network node AP 0.

If only the wireless communication module provides the wired network to the wired network card eth0, the system only detects that the wired communication module provides the wired network to the wired network card eth0, and only the wired network card eth0 up is present at this time, the wired network provided by the wired communication module to the wired network card eth0 is determined as the first network, the wired network can be provided to the second device 600 through the hotspot network node AP0, and the second device 600 accesses the wired network. Then a first route between the wired network card eth0 and the wired network node eth1 is created, so that the wired network card eth0 can provide the first device 500 with the wired network through the first route, enabling the first device 500 and the second device 600 to access the same local area network. I.e. the current wired network card eth0 provides the first device 500 with a network via the wired network node eth1 and the second device 600 via the hot spot network node AP 0.

As shown in the data sharing system frame diagram of fig. 9, if neither the wired communication module nor the wireless communication module provides a network to the display device 200, both the wired network card and the wireless network card are down (neither are in a normal operation state), and at this time, data sharing between the first device 500 and the second device 600 cannot be achieved in the manner in the above-described embodiments. If the wireless communication module is currently providing a network to the display device 200, i.e. the first device 500 and the second device 600 are simultaneously accessing the network provided by the wireless network card WLAN 0. And it is detected that the wired communication module provides the network to the wired network card eth0, at this time, determining the network provided by the wireless communication module to the wireless network card WLAN0 as the first network may be canceled, and determining the wired network provided by the wired communication module to the wired network card eth0 as the first network again, and deleting the first route between the wireless network card WLAN0 and the wired network node eth1, thereby creating the first route between the wired network card eth0 and the wired network node eth 1. At this time, the network accessed by the first device 500 is switched to the network provided by the wired network card eth0, and at the same time, the network accessed by the second device 600 is also switched to the network provided by the wired network card eth 0. In this way, the original first device 500 and the second device 600 simultaneously access the network provided by the wireless network card, and the network provided by the first device 500 and the second device 600 simultaneously access the wired network card is changed.

In addition, if the current wired communication module and the wireless communication module simultaneously provide networks to the wired network card eth0 and the wireless network card WLAN0, respectively, the first device 500 and the second device 600 are provided with networks by the wired network card eth0 for wired connection such that the first device 500 and the second device 600 access the same local area network according to the above embodiments. During the packet transmission, the wired communication module suddenly fails, or the wired network card eth0 fails, resulting in the wired network card eth0 not providing a network to the first device 500 and the second device 600. At this time, after the system detects the fault, the wireless network card may be started, so that the wireless network card up provides a wireless network through the hot spot network node AP0, and after deleting the first route between the wired network card eth0 and the wired network node eth1, a first route between the wireless network card WLAN0 and the wired network node eth1 is created, so that the wireless network card WLAN0 may provide a wireless network to the first device 500 through the wired network node eth 1. Therefore, the method for creating the route can avoid the influence of script limitation on the success rate, and can also cope with the influence of network switching or network instability on the success rate of route creation, so that the success rate of route creation can be better improved, and the success rate of data sharing is improved.

In some embodiments, if there are at least two second devices 600 connected to the local area network accessed by the current display device 200 through the hotspot network node AP0, each of the at least two second devices 600 may implement mutual transmission of data packets with the first device 500. As shown in fig. 12, the controller of the display apparatus 200 may perform the following steps at this time:

step S201, displaying a device list on the display, where the device list includes at least two second devices 600; at least two second devices 600 may access the current hotspot network through the hotspot name and the hotspot password, the display device 200 detects the access signals of at least two second devices 600, the names of the second devices 600 accessing the hotspot network may be added to the device list, as shown in the user interface schematic diagram of fig. 13, and a prompt dialog box may be popped up in the user interface of the display device 200, where the prompt dialog box includes prompt information and the device list. The prompt information may be: there are currently devices that want data sharing, and devices that select data sharing. Through the list of devices, the user can determine which second devices currently have access to the hotspot network.

Step S202, receiving a selection instruction input by a user, wherein the selection instruction characterizes the selected second device in the device list; in the user interface shown in fig. 13, if the selector focus is on the device a, the user clicks the confirm button control, and then generates a corresponding selection instruction according to the operation input by the user, the selection instruction at this time characterizing the device a as the selected second device 600.

Step S203, according to the selection instruction, controls the first device to transmit a data packet to the selected second device based on the second route and the first network, or controls the selected second device to transmit a data packet to the first device based on the second route and the first network. Based on the example of step S202, the currently selected second device 600 is device a, so the control device a transmits a data packet to the first device 500 based on the second route and the first network, or the control device 500 transmits a data packet to the device a based on the second route and the first network. Thus, operation on the display device 200 may be implemented, controlling data sharing between different devices sharing a network of display devices 200. It should be noted that, if the display device 200 shares a network to one second device 600 through the hotspot network node AP0, the prompt dialog box shown in fig. 13 does not need to be popped up on the display device 200. The data sharing process between the first device 500 and the second device 600 may be performed directly.

In addition, the first device 500 may also share data with multiple second devices 600 at the same time. In the user interface shown in fig. 14, a check box is further provided after the device names of the device list, and if the user clicks the check box corresponding to the device name, it indicates that the device needs to be selected as the second device 600 to share data with the first device 500. The user may click on the check boxes corresponding to the device names at the same time, indicating that a plurality of devices need to be selected as the second device 600 to share data with the first device 500.

For example, the user clicks the check box corresponding to the device a and the check box corresponding to the device B, that is, needs to select the device a and the device B as the second device 600 to share data with the first device 500. After the user simultaneously checks the check box corresponding to the device a and the check box corresponding to the device B as the selected states, then clicks the confirm button control, and the selection instruction generated at this time characterizes that the device a and the device B are simultaneously selected as devices needing to share data with the first device 500. The display device 200 may send the selection instruction to the hotspot network node AP0, so that the hotspot network node AP0 may transmit the data packets sent by the device a and the device B to the first device 500 at the same time, so as to realize that the first device 500 performs data sharing with the device a and the device B at the same time.

In some embodiments, if there are multiple networking capable network cards providing a network to the display device 200, the type of data that the first device 500 or the second device 600 needs to share may be acquired in advance, and then different networking capable network cards may be selected according to different data types. For example, the current display device 200 is configured with a wired network card and a wireless network card, where the wired network provided by the wired network card is more stable than the wireless network provided by the wireless network card. If the display apparatus 200 acquires that the data to be shared by the first apparatus 500 or the second apparatus 600 is of the video type in advance, it is necessary to perform data sharing using a relatively stable wired network. The cable network card can be controlled to provide the first device 500 and the second device 600 with the cable network at the same time in the manner of the above-described embodiment. If the display device 200 realizes that the data to be shared by the first device 500 or the second device 600 is of a text type, the data sharing may be performed by using a wireless network. The wireless network card can be controlled to provide wireless networks for both the first device 500 and the second device 600 in the manner of the above-described embodiments.

Specific examples of the present application based on the above embodiments are as follows: the first device 500 is an ops computer, the second device 600 is a mobile phone terminal, and an IP address (for example 192.168.44.1, a subnet Mask of 255.255.255.0) is configured in advance for the wired network node eth1 of the display device 200. As shown in fig. 15 and 16, specific examples include the following steps:

In step S3010, after the display device 200 and the ops computer are powered on synchronously, the wired path from USB to LAN is valid, and at this time, the Android system of the display device 200 can detect the wired network node eth1 up.

Step S3011, after detecting that the path between the ops computer and the wired network node eth1 is open, the process of requesting the IP may be started according to the process of inserting the network cable normally, and finally the wired network card of the ops computer may obtain an IP address of 192.168.44 network segment, so that the process of implementing the sharing of the network by the display device 200 to the ops computer is completed.

Step S3012, configuring data forwarding of the wired network node eth1 (USB 1), configuring routing, and adding interception of other network nodes (interception of the upstream network relative to the wired network node eth1 includes interception of the wired network card eth0, wireless network card WLAN0 (USB 2), and AP 0).

Step S3013, if there is a change in the listening uplink network, adding a policy route of the uplink network to the wired network node eth1 so that the data packet can be transmitted from the wired network node eth1 to other nodes.

If the wired network card eth0 up is monitored, the IP address of the wired network card is obtained, and the route between the wired network card eth0 and the wired network node eth1 is configured, so that the data packet can be transmitted from the wired network card eth0 to the wired network node eth 1. If the wireless network card WLAN0 up is monitored, the IP address of the wireless network card is acquired, and the route between the wireless network card WLAN0 and the wired network node eth1 is configured, so that the data packet can be transmitted from the wireless network card WLAN0 to the wired network node eth 1. If the Android system of the display device 200 monitors that the hotspot is started, the IP address of the hotspot network node AP0 is obtained, and a route between the hotspot network node AP0 and the wired network node eth1 is configured, so that a data packet can be transmitted from the hotspot network node AP0 to the wired network node eth 1.

If the mobile phone terminal is connected to the network currently accessed by the display device 200 through the hot spot, the ops computer is also connected to the network currently accessed by the display device 200, so that the mobile phone terminal and the ops computer are accessed to the same local area network, and data sharing between the mobile phone terminal and the ops computer can be finally realized based on the route configured between the hot spot network node AP0 and the wired network node eth 1. The data sharing process may be that the mobile phone terminal projects the content being displayed on the display screen to the ops computer, or the ops computer projects the content being displayed on the display screen to the mobile phone terminal.

It should be noted that, after the ops computer and the mobile phone terminal access the same lan, and the route configuration between the hotspot network node AP0 and the limited network node eth1 is completed, the screen-throwing process may be performed without user operation. The route between the ops computer and the mobile phone terminal can also be set, for example, to allow only the ops computer to throw a screen to the mobile phone terminal, or to allow only the mobile phone terminal to throw a screen to the ops computer. Or the display device 200 may be configured to receive the contents displayed by the current display screens of the ops computer and the mobile phone terminal, and if the current display of the ops computer is video contents and the current display of the mobile phone terminal is not video contents, the video contents displayed by the current display of the ops computer are projected to the mobile phone terminal preferentially. If the current display of the mobile phone terminal is video content and the ops computer is currently black screen or the display of the mobile phone terminal is not video content, the video content currently displayed by the mobile phone terminal is preferably projected to the ops computer.
