Based on this, the display device provided in this embodiment and the sensorless distribution network control method based on the USB channel will be described below by taking an intelligent television as an example.

In some embodiments, please refer to fig. 6, and in some embodiments, please refer to fig. 6, the smart tv includes: a display for displaying a user interface containing an application; the base is connected with the display end through a USB network interface; the network card comprises a first wired network card, a second wired network card and a wireless network card; the display end is connected with the base end through a USB connecting wire, and the display end is connected with a wired network accessed on the base through a USB network access. It should be noted that, both the display and the base are configured with a wireless network card, and the wireless network card of the display is used to access a proprietary network link through the wireless network card when the base is separated, so that independent internet access can be realized when the display is separated from the base.

In some embodiments, the network card comprises a first wired network card, a second wired network card, and a wireless network card; the first wired network card and the second wired network card of the smart television can be simultaneously accessed to different network links, or the first wired network card and the wireless network card of the display device can be simultaneously accessed to different network links, so that the display device can be simultaneously accessed to the first network link and the second network link. Specifically, the smart television further comprises a first network cable interface arranged on the base and connected with the first wired network card, and a second network cable interface connected with the second wired network card.

In some embodiments, the smart television may be used in the application scenario shown in fig. 7, that is, the smart television is used as a home tablet, and one network communication channel may be used to connect to a network route in a community local area network, so that the smart television may communicate with a portal machine, a property manager, a community server, and the like, and access to a wide area network through a first wired network card corresponding to a first network link; the other network communication channel can be used for connecting a home network route communicated with the Internet, and comprises a wired network and a wireless network, so that games, video and audio applications and the like needing to be connected with the Internet can be used, and the wide area network can be accessed through a second wired network card or the wireless network corresponding to a second network link.

In some embodiments, when the display is started, receiving an application starting operation instruction sent by a user; and when an operation instruction of starting the application by a user is received, determining the network segment to which the application data belongs so that different applications are accessed to the local area network through different network links based on different routing rules.

In some embodiments, the smart television receives an application starting operation instruction sent by a user when the display is started, and fig. 8 shows a display interface when the display of the smart television is turned on.

Fig. 9 shows a schematic diagram of a user interface of a smart television according to an embodiment of the present application, as shown in fig. 9, a first application program that is installed on a display of the smart television and can be used for a community network application includes a door intercom doorbell application, a community visual outpatient application, and an elevator call or smart door lock application; and meanwhile, installing a second application program for the common network application, namely a first video application, a second video application and a third video application which can be used for video playing.

In some embodiments, the community network application includes data generated by related applications such as video intercom, calling elevator or intelligent door lock, for example, when the calling elevator application in the intelligent television is opened, a related interface of the calling elevator application is displayed in the display, and the calling elevator is successful through an instruction of calling the elevator input by the user. When a user starts a first application on a display interface, wherein the first application is a general name including community network applications, and after the controller receives a starting instruction, the controller controls data generated by the related applications to carry out network communication through a first wired network card corresponding to a first link network corresponding to the related applications. For example, the controller controls the display to display a video intercom picture on the display interface when monitoring that the related function of the video intercom application is started. In the using process of the community application such as the community application, the data generated by the related application is controlled to carry out network communication through the first wired network card corresponding to the first link network corresponding to the related application. Illustratively, when the intelligent television only starts the talkback doorbell application, the controller controls the first wired network card to drive the corresponding first network link, so as to provide data communication for the first application of the foreground user interface playing the video program. It can also be understood that the intercom doorbell application started at this moment on the foreground user interface performs network communication through the first wired network card of the smart tv, as shown in fig. 10.

In some application scenes, the intelligent television is connected with the talkback doorbell at the user gate through the proprietary link network, when the talkback doorbell is started, because the intelligent television is split, the base end can be disconnected with the display end, but the normal use of a network access is not influenced, the user can establish connection with the doorbell equipment through the display at a position far away from the base end, so that the user experience is improved, the problem that the user can only use the display equipment when reaching a specified position is avoided, and the user experience is improved.

In some embodiments, when applications such as media resources need to be opened on the smart television, and web browsing or video playing needs to connect to the internet, the user starts the second application shown in fig. 9 through desktop operation of the smart television, and if the application is a non-community network application, after the second application is started, the data generated by the application is controlled to perform network communication through the second wired network card or the wireless network card corresponding to the second network link corresponding to the application. Illustratively, when the smart television starts only the first video application, the controller controls the second wired network card to drive the corresponding second network link, so as to provide data communication for the second application of the foreground user interface playing the video program. It can also be understood that the video program in the foreground user interface at this time is in network communication through the second wired network card of the smart television, as shown in fig. 11. For another example, when the smart television only starts the first video application, the controller controls the wireless network card to drive the corresponding second network link, so as to provide data communication for the second application of the foreground user interface that is playing the video program. It can also be understood that the video program in the foreground user interface at this time is in network communication through the wireless network card of the smart tv, as shown in fig. 12.

In some embodiments, when the smart television may use multiple networks, a first wired network card and a second wired network card of the smart television may access different network links at the same time, and the smart television may play a video application in the second application through the network link accessed by the second wired network card, and also may control the community application to execute a corresponding operation through the first wired network card at the same time, for example, when the first video application is played on the smart television, a user may execute a call elevator function by calling an elevator application, and may also receive an external doorbell call through an intelligent door lock application, as shown in fig. 13.

In some embodiments, the first wired network card and the wireless network card of the smart television may access different network links at the same time, so that the display device may access the first network link and the second network link at the same time, where the network cards that are accessed are different, but the smart television interface displays the same interface as the display device that accesses the first wired network card and the second wired network card at the same time, as shown in fig. 14.

Therefore, if the application does not select a corresponding network for transmission during the use process, the related functions of the application cannot be realized. For example, in the embodiment of the present application, the community-class application is controlled to perform network communication through the first wired network card corresponding to the first link network, the non-community-class application, that is, the related application of the traditional network data resource transmission is controlled to perform network communication through the second wired network card corresponding to the second network link, if the network does not set a corresponding network channel according to requirements in the setting process, the above-mentioned proprietary network transmission cannot be implemented, and the related application cannot be started.

The above network access for different types of applications to different network links is realized based on the intelligent routing method based on the USB channel provided in this embodiment, and the method is explained in detail below.

The intelligent routing method based on the USB channel provided by the embodiment of the application is used for the intelligent television and comprises the following steps:

the base terminal starts a protocol scheme of a remote network driving interface, and shares the second wired network card to the USB network service, referring to fig. 15, which specifically includes the following steps:

s11: when the display is connected to the base through the USB interface, a first service for starting USB network sharing is established, wherein the first service can monitor the connection state of the network card and dynamically share the connected network card to the USB interface.

The accessed network card is dynamically shared to the USB interface, so that the USB interface end can sense the accessed network card and realize the dynamic sharing of the interface, namely, the interface conversion based on different network cards is realized at the USB interface end, and thus, different application data are accessed to different network links through the USB network sharing. It should be noted that, in this embodiment, another way to dynamically share the accessed network card to the USB interface is to dynamically nat the accessed network card to the USB interface, where the meanings of the english expressions are the same.

It should be noted that, the monitoring of the network card access network link by the first service specifically includes the following steps: monitoring that a second wired network card is accessed to a wired network link; or monitoring that the wireless network card is accessed to the wireless network link.

In some embodiments, based on the usage scenario of the split type smart television shown in fig. 6, the first wired network card and the second wired network card connected to the base need to be shared with the USB network channel, so that when the display is connected to the base through the USB connection line, multiple network links on the base can be used.

S12: and when the second wired network card is accessed to a second network link, controlling the first service to start the USB wireless network card and controlling the second wired network card to share the USB network so that the second application can access the wide area network through the second network link accessed by the second wired network card.

FIG. 16 is a functional flow chart illustrating the USB network sharing and the remote network driver interface protocol.

In some embodiments, referring to fig. 16, when the display is connected to the base through the USB interface, the created first service may monitor that the USB wireless network card is connected to the kernel, the control kernel notifies the network daemon process through the event mechanism, and the network daemon process starts the network process service to notify the network sharing to add the network interface when receiving the notification, so that the network process controls the USB network sharing to be automatically started after monitoring the message.

After the USB network sharing is automatically started, the network process is connected with the network management server through the network management client, and then is connected to the sharing class. And then controlling and calling the network service class, sending an instruction to the underlying network service class through a daemon thread, and finally sending a command to the kernel by the underlying network service class to realize the function of opening a remote network driving interface protocol.

After the remote network driver interface protocol function is turned on, when a second wired network card is accessed to a second network link, the controller writes a network agent class containing a second wired network card address acquired based on an android frame process into the second wired network card and the kernel so that a second application can access the wide area network through the second network link accessed by the second wired network card.

In some embodiments, the controller writes a network proxy class including an address of a second wired network card acquired based on an android framework flow into the second wired network card and the kernel, and specifically includes: the control network daemon process sends a network monitoring message to the Ethernet tracing class to create an Ethernet factory class, so that the Internet interconnection protocol control service obtains a second wired network card address; and writing the network agent class containing the address of the second wired network card into the second wired network card and the kernel.

S13: when the first wired network card is accessed into a first network link, a first wired network card address which is acquired by a dynamic host configuration protocol server side through a dynamic host configuration protocol client side is written into the first wired network card and the inner core, so that a first application can access a wide area network through the first network link accessed by the first wired network card, wherein the first network link and a second network link can be simultaneously accessed into the wide area network.

In some embodiments, since the second wired network card, i.e., the second wired network or the wireless network, acquires the IP address based on the android native flow, when the remote network driver interface protocol switch is turned on, the IP address is automatically shared to the USB wireless network card, but the first wired network needs to acquire the IP address through the dynamic host configuration protocol client, so that the default is not shared, and the first wired network is shared to the USB network access after the IP is successfully acquired.

Fig. 17 is a schematic flow chart illustrating a process of acquiring a first wired network card node.

When the first wired network card is accessed into the first network link, monitoring a first wired network card node/sys/class/net/USB 0, if the first wired network card node exists, starting the IP address of the first wired network card acquired by the dynamic host configuration protocol client, and if the first wired network card node does not exist, continuing waiting. And the dynamic host configuration protocol server acquires the IP and writes the IP into the network card, and then registers the IP into the kernel.

When the first network link accesses the intelligent television through the first wired network interface shown in fig. 6, the controller will monitor that the first wired network card node exists, and will start the dynamic host configuration protocol client service to enter a state waiting for acquiring the IP, and acquire the IP address of the first wired network.

Based on this, in some embodiments, the controller is configured to perform monitoring of a first wired network card node corresponding to a first network link, and acquire a first wired network card address, including: monitoring a first wired network card node corresponding to a first network link; if a first wired network card node corresponding to the first network link exists, acquiring a first wired network card address; and if the first wired network card node corresponding to the first network link does not exist, indicating that the first wired network is not accessed, waiting to acquire the address of the first wired network card.

And the dynamic host configuration protocol server acquires the IP and writes the IP into the network card, and then registers the IP into the kernel so that the first application can access the wide area network through the first network link accessed by the first wired network card.

And after the dynamic host configuration protocol client successfully acquires the IP, adding default data to a routing table USB0 by using a routing rule of a USB network access. Then, the priority of the routing table USB0 is adjusted to be higher than that of other user routing tables, and the method specifically comprises the following steps:

fig. 18 is a schematic diagram of a routing rule creation flow.

S21: and creating a routing rule of the first wired network card according to the address of the first wired network card, and adding the routing rule into a first routing table.

In the system routing table, the routing tables have a priority relationship, the smaller the numerical value of the priority corresponding to each routing table is, the higher the level is, when the data transmission is monitored to be needed, the wired transmission is judged to be carried out through the routing rule with the high priority level in the system routing table according to the priority. Therefore, after the routing table is established, the value of the priority corresponding to the routing table needs to be set, in this embodiment, the priority of the first wired network card routing table is established, so that the priority of the first wired network card routing table is higher than that of the second wired network card and the wireless network card. When data is transmitted, the data is preferentially transmitted through the first wired network card corresponding to the first network link, and when the data does not belong to the network segment corresponding to the first wired network, the data is transmitted through the second wired network card or the wireless network card.

In some embodiments, default data is added to the first routing table according to a routing rule of the first routing table, after application data transmitted by a display terminal is received, a network segment to which the application data belongs is determined first, and when the application network segment does not belong to a network segment to which a first wired network card corresponding to a first network link is located, the network segment is distributed to a second wired network card corresponding to a second network link.

S22: and creating a numerical value of the priority corresponding to the first routing table, so that the priority of the first routing table is higher than that of a second routing table, and the second routing table is a routing table configured with a second wired network card routing rule.

In some embodiments, the first routing table may be created with a value corresponding to a priority. Firstly, acquiring a numerical value of a second priority in a system routing table, namely the priority is second to the priority of a local routing table, if the numerical value of the second priority is less than 10000, indicating that a route is created under the priority, setting the routing table corresponding to the priority as a routing table num, inquiring routing configuration information stored in the routing table num corresponding to the second priority, and deleting the routing configuration information. And simultaneously, the numerical value of the deleted priority is a routing table corresponding to a preset value, and the preset value is between 0 and 10000, excluding 0 and 10000.

If the value of the second priority is not less than 10000, it indicates that the routing table is created for the first time in the second priority. A preset value is taken as the numerical value of the second priority, and the first reason table is added to the priority.

The routing tables are set in the above manner, so that the priority of the first routing table is higher than that of the second routing table, and it should be noted that the second routing table is a routing table configured with a second wired network card and a wireless network card routing rule. When data transmission is needed, the routing rule corresponding to the first routing table is preferentially selected due to the fact that the priority corresponding to the first routing table is high, and therefore network communication of community applications through the first wired network card corresponding to the first link network is achieved, and related functions of network communication of non-community applications, namely related applications of traditional network data resource transmission, through the second wired network card corresponding to the second network link are achieved. In addition, the above values regarding the priority are only examples, and those skilled in the art may set different values as needed.

In some embodiments, when an instruction that a user enables a first application in the smart television is received, it is first determined to which network segment data generated by the application belongs, for example, if the routing rule of the first wired network card is set to be 192.168.1 ° in the IP address range of the first wired network, all IP addresses in the network segment 192.168.1 ° are transmitted through the first wired network. For example, if the obtained IP address is 192.168.1.100 and the subnet mask is 255.255.255.0, it is determined that the network segment belongs to the IP address range of the first wired network, and therefore, all data transmission is performed through the first wired network card corresponding to the first network link. If the acquired IP address does not belong to the IP address range of the first wired network, according to the priority ranking, the acquired IP address is assigned to follow the routing rule of the second routing table, and the related application data transmission is transmitted through a second wired network card or a wireless network card corresponding to the second network link.

Fig. 19 is a schematic view of an overall process flow of an interaction process between a display and two ends of a base of an intelligent routing method based on a USB channel according to an embodiment of the present application, where the process flow includes the whole processes of acquiring an IP address, writing the IP address, transmitting data, and obtaining an intelligent route, and when it is necessary to acquire IP addresses of a first wired network and a second wired network at the same time, the process flow is performed in the following manner:

in some embodiments, when there is a wired network access device, the network daemon notifies the ethernet trace class to obtain IP in the ethernet factory class through the ipsec controller. After the IP is obtained, the double-wire network and the network agent class object can be generated and registered in the network connection management service. The decision as to which network to connect is ultimately scored in a network connection management service, which then informs the kernel. If the two wired networks score equally high, the later connected wired networks will be eliminated.

In some embodiments, when acquiring an IP address for a dual-wired network, a service for acquiring an IP address for a first wired network is designed. First, the service will query whether the first wired network node exists, and if so, the service will start the first wired network card after the network node is ready. And then, the IP is acquired through the client side of the dynamic host configuration protocol, the IP is acquired when the server side of the dynamic host configuration protocol receives the request, and then the information such as the IP is written into the network card.

The second wired network also acquires the IP through the aforementioned procedure. When the second wired network accesses the device, the network daemon will inform the Ethernet trace class to create a factory class to get the IP through the Internet protocol controller. And after the IP is acquired, the second wired network generates a network proxy object and registers the network proxy object in the network connection management service. And writing the network connection management service into the kernel and the network card so as to complete the subsequent operation.

According to the technical scheme, on the premise that the android system device is connected with at least two networks, when the display is connected with the base through the USB connecting line, the intelligent routing method based on the USB channel, provided by the embodiment, realizes dual-network intelligent routing, and enables data to be automatically transmitted according to the transmission rule. In specific application, the design scheme of the intelligent route based on the USB channel can realize that the display screen shares the double-network connection function to the base through the wireless network channel, and can dynamically add the route, so that data are respectively transmitted to the two wired network cards according to rules.
