Description

Technical Field

[0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a data transmission method, an electronic device, and a storage medium. Background Art

[0002] With the continuous development of electronic technologies, various forms of electronic devices have emerged and are applied in various fields of social production activities. For example, in scenarios for multi-person communication such as an electronic classroom, an all-in-one machine with a relatively large size is usually set up to present focus information for multi-person communication. Multiple system modules are usually configured in the all-in-one machine, and multiple system modules using the same or different operating systems operate highly independently and in cooperation, so that users can implement various functions such as file display, handwriting input, and on-site data collection required in multi-person communication on the all-in-one machine. Participants in multi-person communication can largely realize the digital presentation, digital recording, and digital transmission of various information during the multi-person communication process, effectively improving the efficiency of multi-person communication.

[0003] When the inventor used an existing all-in-one machine to perform data transmission by connecting a wireless terminal device and the all-in-one machine during a multi-person communication activity, it was found that, in the external form of the all-in-one machine as a whole device, there are multiple independent system modules inside. The wireless terminal device needs to establish a connection with the actually working system module to complete data transmission. The actually working system module of the all-in-one machine often switches. In order to enable multiple system modules to perform data transmission with the wireless terminal device, a relatively high hardware cost is required, and switching operations need to be performed multiple times. The connection operation during the data transmission process is complex, and the continuity of the transmitted data during the data transmission process is greatly interfered. Summary of the Invention

[0004] The present invention provides a data transmission method, an electronic device, and a storage medium to solve the technical problems of complex connection operations during the existing data transmission process and great interference with the continuity of the transmitted data during the data transmission process.

[0005] In a first aspect, an embodiment of the present invention provides a data transmission method. The data transmission method is applied to a first system module. The first system module includes a first physical wireless network card and a first connection network card. The first system module is used to connect to a second system module through the first connection network card. The data transmission method includes:

[0006] Enumerate the first physical wireless network card as a point-to-point group master network card and a wireless terminal network card;

[0007] When the second system module is detected to be connected, configure the IP addresses of the point-to-point group owner network card, the first connection network card, and the second system module, so that the IP address of the first connection network card and the IP address of the second system module are in the same network segment, and the IP address of the first connection network card and the IP address of the point-to-point group owner network card are in different network segments;

[0008] When a network data packet with a destination address of the IP address of the point-to-point group owner network card and a port number of the first port number is received from the wireless terminal device through the wireless connection between the point-to-point group owner network card and the wireless terminal device, distribute the network data packet to the first screen mirroring application installed in the first system module for processing;

[0009] When a network data packet with a destination address of the IP address of the point-to-point group owner network card and a port number of the second port number is received from the wireless terminal device through the wireless connection, modify the destination address of the network data packet to the IP address of the second system module, and forward the network data packet to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and is processed by the second screen mirroring application installed in the second system module.

[0010] As described above, the first system module enumerates the first physical wireless network card as the point-to-point group owner network card and the wireless terminal network card, configures the first connection network card and the second system module in the same network segment, configures the point-to-point group owner network card and the first connection network card in different network segments, and establishes a data distribution mechanism based on port mapping between the point-to-point group owner network card and the first connection network card. When a network data packet with a destination address of the IP address of the point-to-point group owner network card and a port number of the first port number is received from the wireless terminal device through the point-to-point group owner network card, distribute the network data packet to the first screen mirroring application installed in the first system module for processing. When a network data packet with a destination address of the IP address of the point-to-point group owner network card and a port number of the second port number is received from the wireless terminal device through the point-to-point group owner network card, modify the destination address of the network data packet to the IP address of the second system module, and forward the network data packet to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and is processed by the second screen mirroring application installed in the second system module. After the wireless terminal device establishes a wireless connection with the first system module, it can quickly send network data packets to any system for processing. This solution only needs to set one wireless network card in the electronic device to meet the requirement of the wireless terminal device to switch the local area network transmission with any system module at any time, and at the same time meet the requirement of the wireless terminal device to access the Internet through the electronic device. It simplifies the connection operation of repeatedly connecting devices during the data transmission process, has low hardware cost, is simple and convenient to operate, and improves the continuity of data and the connection stability during the data transmission process.

[0011] After enumerating the first physical wireless network card as the peer-to-peer group master network card and the wireless terminal network card, it further includes:

[0012] When detecting the access of the second system module, establish a first NAT connection between the peer-to-peer group master network card and the first connection network card.

[0013] Through the first NAT connection, the overall external Internet communication of the electronic device with the first system module and the second system module can be realized.

[0014] After establishing the first NAT connection between the peer-to-peer group master network card and the first connection network card, it further includes:

[0016] In addition to being able to send screen mirroring data to the first device, the wireless terminal device can also realize external Internet communication through the electronic device based on the first NAT connection.

[0017] After configuring the IP addresses of the peer-to-peer group master network card, the first connection network card, and the second system module when detecting the access of the second system module, so that the IP address of the first connection network card and the IP address of the second system module are in the same network segment, and the IP address of the first connection network card and the IP address of the peer-to-peer group master network card are in different network segments, it further includes:

[0018] When receiving a network data packet whose destination address is the IP address of the peer-to-peer group master network card and the port number is not the first port number or the second port number through a wireless connection from the wireless terminal device, send the network data packet to a preset default screen mirroring application for processing, and the default screen mirroring application is one of the first screen mirroring application and the second screen mirroring application.

[0019] For the network data packet generated by the quick screen mirroring operation where the user does not select a screen mirroring target, it can be directly processed by the preset default screen mirroring application to achieve quick screen mirroring.

[0020] After enumerating the first physical wireless network card as the peer-to-peer group master network card and the wireless terminal network card, it further includes:

[0021] When the access of the second system module is not detected, establish a second NAT connection between the peer-to-peer group master network card and the wireless terminal network card.

[0022] In the case where the access of the second system module is not detected, through the second NAT connection between the peer-to-peer group master network card and the wireless terminal network card, the external Internet communication of the electronic device can be realized.

[0023] Among them, the data transmission method further includes:

[0024] When a network data packet whose destination address is not the IP address of the peer-to-peer group master network card is received from a wireless terminal device through a wireless connection, the network data packet is sent to the wireless terminal network card through a second NAT connection, so that the wireless terminal device can access the Internet through the first system module.

[0025] The wireless terminal device can realize external Internet communication based on the second NAT connection through the wireless connection with the electronic device.

[0026] Among them, the first system module is an Android system module, and the second system module is a Windows system module.

[0027] The combined use of different system modules can combine the application advantages of different systems to meet the needs of users in various scenarios.

[0028] In a second aspect, an embodiment of the present invention provides a data transmission method. The data transmission method is applied to a wireless terminal device. The wireless terminal device is wirelessly connected to an electronic device. The electronic device includes a first system module and a second system module. The first system module realizes the wireless connection between the electronic device and the wireless terminal device. The data transmission method is characterized in that it includes:

[0029] Receiving a target selection operation on a screen mirroring target selection window, where the screen mirroring target selection window displays a first selection control corresponding to the first system module and a second selection control corresponding to the second system module;

[0030] According to the target selection operation, obtaining the current display screen as the screen mirroring screen, and generating a network data packet with the IP address of the first system module as the destination address and the first port number corresponding to the first system module or the second port number corresponding to the second system module as the port number;

[0031] Sending the network data packet to the first system module, so that the first system module distributes the network data packet to the first screen mirroring application installed in the first system module for processing according to the first port number, or forwards the network data packet to the second system module according to the second port number, and the second screen mirroring application installed in the second system module processes it.

[0032] As described above, the first system module enumerates the first physical wireless network card as a peer-to-peer group master network card and a wireless terminal network card, configures the first connection network card and the second system module in the same network segment, configures the peer-to-peer group master network card and the first connection network card in different network segments, and establishes a data distribution mechanism based on port mapping between the peer-to-peer group master network card and the first connection network card. When a network data packet with the IP address of the peer-to-peer group master network card as the destination address and the first port number as the port number is received from a wireless terminal device through the peer-to-peer group master network card, the network data packet is distributed to the first screen mirroring application installed in the first system module for processing. When a network data packet with the IP address of the peer-to-peer group master network card as the destination address and the second port number as the port number is received from a wireless terminal device through the peer-to-peer group master network card, the destination address of the network data packet is modified to the IP address of the second system module, and the network data packet is forwarded to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and processed by the second screen mirroring application installed in the second system module. After the wireless terminal device establishes a wireless connection with the first system module, only by selecting the screen mirroring target, network data packets can be quickly sent to any system for processing. This solution only needs to set a wireless network card in the electronic device to meet the requirement of the wireless terminal device to switch the local area network transmission with any system module at any time, and at the same time meet the requirement of the wireless terminal device to access the Internet through the electronic device, simplifies the connection operation of repeatedly connecting devices during data transmission, has low hardware cost, is simple and convenient to operate, and improves the continuity of data and the high connection stability during data transmission.

[0033] Among them, the data transmission method further includes:

[0034] When a quick screen mirroring operation is received, obtain the current display screen as the screen mirroring screen, and generate a network data packet with the IP address of the first system module as the destination address and no port configured;

[0035] Send the network data packet to the first system module, so that the first system module sends the network data packet to a preset default screen mirroring application for processing, and the default screen mirroring application is one of the first screen mirroring application and the second screen mirroring application.

[0036] For the network data packet generated in response to the quick screen mirroring operation where the user does not select a screen mirroring target, it can be directly processed by the preset default screen mirroring application to achieve quick screen mirroring.

[0050] To make the objectives, technical solutions, and advantages of this application more clear, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are used to explain the present invention rather than limit the present invention. Additionally, it should be noted that for ease of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0051] It should be noted that due to space limitations, the specification of this application does not enumerate all optional implementation manners. After reading the specification of this application, those skilled in the art should be able to think that as long as the technical features do not conflict with each other, any combination of technical features can constitute an optional implementation manner.

[0052] The following will explain each embodiment in detail.

[0053] In an electronically implemented multi-person communication scenario, usually, an all-in-one machine 10 with a relatively large size as shown Figure 2 is set to present focus information for multi-person communication. The all-in-one machine 10 is equipped with multiple devices such as microphones, speakers, cameras, etc. to assist in information collection and output. Usually, multiple system modules are also configured in the all-in-one machine 10. Multiple system modules using the same or different operating systems operate highly independently and in cooperation, so that users can implement various functions required in multi-person communication on the all-in-one machine, effectively improving the multi-person communication efficiency. It should be understood that the all-in-one machine 10 is just a naming definition for such a device, which is used to carry the system modules provided in the embodiments of this application. Such a device can also be named an interactive flat panel, a conference flat panel, an interactive intelligent flat panel, a conference large board, an electronic device, etc.

[0054] In the process of multi-person communication activities of existing all-in-one machines, a common data transmission method is to connect a wireless terminal device to the all-in-one machine for data transmission; however, in the external form of the all-in-one machine as a whole device, multiple internally arranged independent system modules actually need to establish a connection with the corresponding system module to complete data transmission. When the data transmission target changes, it is necessary to operate on the wireless terminal device to switch the connected system module. The data transmission between a wireless terminal device (such as a mobile phone, a laptop computer, a tablet computer, etc.) and the system modules in the all-in-one machine is mostly based on local area network transmission, that is, it is necessary to first connect the WiFi of the wireless terminal device and the all-in-one machine to the same WiFi hotspot, or the all-in-one machine itself serves as a WiFi hotspot for the wireless terminal device to connect. In this way, when the wireless terminal device is in two scenarios of accessing the Internet and performing local area network data transmission, it is necessary to switch the working mode of the WiFi, and the two functions of Internet access and local area network data transmission cannot be achieved simultaneously.

[0055] Another solution is that the wireless terminal device can directly connect point-to-point with the all-in-one machine through the WiFi Direct method without disconnecting the original connected WiFi hotspot, so as to simultaneously access the Internet and transfer data with the all-in-one machine. However, the WiFi Direct point-to-point connection method can only be connected to the wireless network card corresponding to one system module. Multiple system modules need to set multiple wireless network cards to achieve the WiFi Direct point-to-point connection between each device and the wireless terminal device.

[0056] The connection process of the WiFi Direct point-to-point connection can refer to Figure 3 , in the all-in-one machine 10, a first system module 11 and a second system module 12 are provided, and they use different operating systems. The first system module 11 is exemplarily an Android module, and the second system module 12 is exemplarily a Windows module. Among them, the second system module 12 is an OPS (Open Pluggable Specification) system module and is a pluggable module. In the all-in-one machine 10, a first network card 111 and a first WiFi module 112 are correspondingly configured for the first system module 11, and a second network card 121 and a second WiFi module 122 are correspondingly configured for the second system module 12. Among them, the first network card 111 and the second network card 121 are used to establish a communication link dedicated to between the first system module 11 and the second system module 12, to achieve the overall coordinated control of the two system modules inside the all-in-one machine 10, and present an overall interaction effect of a set of operating system outward. The communication link between the first system module 11 and the second system module 12 and the communication link formed between the all-in-one machine and the wireless terminal device 20 belong to different network segments, such as the 192.168.153.xx network segment and the 192.168.154.xx network segment shown in FIG. 3. The first WiFi module 112 is used for the first system module 11 to communicate with devices outside the all-in-one machine 10 through the Internet; the second WiFi module 122 and other physical network cards (such as Figure 3 the Internet access network card shown in) are used for the second system module 12 to communicate with devices outside the all-in-one machine 10 through the Internet. The wireless terminal device 20 (such as various smart phones) can establish a communication connection with the all-in-one machine 10 through various wireless methods. However, the all-in-one machine 10 is a whole device form. Actually, the system module controls the connection process and the data processing process based on the connection. The wireless terminal device 20 can directly connect to the WiFi hotspot provided by the system module.

[0057] For example Figure 3Exemplarily, a first WiFi module 112 in the first system module 11 provides a WiFi hotspot. The wireless terminal device 20 can establish a connection with the first system module 11 through the third WiFi module 21 to form a communication link as shown in ①, so as to access the Internet through the communication link ①. The wireless terminal device 20 can establish a WiFi Direct peer-to-peer connection with the first system module 11 and the second system module 12 respectively through WiFi-Direct 22, forming communication links as shown in Figures ② and ③, and can perform local area network data transmission with the all-in-one machine 10 respectively through the WiFi Direct peer-to-peer connection. Therefore, this method can meet the requirements of the wireless terminal device 20 for simultaneous Internet access and local area network data transmission. However, the above communication links ② and ③ cannot be maintained simultaneously. When the main working system module of the all-in-one machine 10 switches between the first system module 11 and the second system module 12, the wireless terminal device 20 needs to disconnect the WiFi Direct peer-to-peer connection with the system module before the switch, and then re-establish the WiFi Direct peer-to-peer connection with the system module after the switch. Figure 3 In the solution of, when there are multiple system modules, corresponding wireless network cards need to be set for each system module, which not only has high hardware costs, but also requires development for each wireless network card, resulting in a huge development workload. Moreover, it is difficult to fully synchronize the information between two wireless network cards, which may lead to connection stability problems.

[0058] There is another solution. The all-in-one machine 10 is provided with a wireless network card, and this wireless network card switches between working system modules as needed. For example, it switches between Figure 3 the first system module 11 and the second system module 12 in. For example, when the first system module 11 switches to the second system module 12, the wireless network card also switches to the second system module 12 accordingly. Although this method can save hardware costs, after the wireless network card switches, there is a waiting time. After re-initialization, it connects to the system module after the switch. During this period, because the wireless network card needs to be restarted and ready, it will affect the user's connection experience. In addition, the external devices that have already been connected to the all-in-one machine will also be disconnected due to the plugging and unplugging of the wireless network card in the form of switching and cannot be used continuously. As a result, when the all-in-one machine 10 switches system modules, the user also needs to reconnect the external devices to the system module after the switch. The all-in-one machine 10 as a whole shows repeated connection of external devices, with complex operations and low efficiency.

[0059] Generally speaking, in the process of connecting a wireless terminal device to an all-in-one machine for data transmission, when the data transmission target changes, it is necessary to operate the wireless terminal device to switch the connected system module. The connection operation during the data transmission process is complex, and the continuity of the transmitted data is greatly interfered.

[0060] Based on the technical problems existing in the prior art, the solution of the embodiment of the present invention is proposed. The first system module enumerates the first physical wireless network card as a point-to-point group master network card and a wireless terminal network card, configures the first connection network card and the second system module in the same network segment, configures the point-to-point group master network card and the first connection network card in different network segments, and establishes a data distribution mechanism based on port mapping between the point-to-point group master network card and the first connection network card. When a network data packet with the destination address being the IP address of the point-to-point group master network card and the port number being the first port number is received from the wireless terminal device through the point-to-point group master network card, the network data packet is distributed to the first screen mirroring application installed in the first system module for processing. When a network data packet with the destination address being the IP address of the point-to-point group master network card and the port number being the second port number is received from the wireless terminal device through the point-to-point group master network card, the destination address of the network data packet is modified to the IP address of the second system module, and the network data packet is forwarded to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and processed by the second screen mirroring application installed in the second system module. After the wireless terminal device establishes a wireless connection with the first system module, it can quickly send network data packets to any system for processing. This solution only needs to set one wireless network card in the electronic device, which can meet the requirement that the wireless terminal device can switch the local area network transmission with any system module at any time, and at the same time meet the requirement that the wireless terminal device accesses the Internet through the electronic device, simplifies the connection operation of repeatedly connecting devices during the data transmission process, has low hardware cost, is simple and convenient to operate, and improves the continuity of data and the connection stability during the data transmission process.

[0061] Figure 1 It is a flowchart of a data transmission method provided by an embodiment of the present application, as Figure 1 shown. When describing the data transmission method from the perspective of the first system module, for clearer description, the corresponding implementation processes of the second system module and the wireless terminal device will be described.

[0062] Step S110: Enumerate the first physical wireless network card as a point-to-point group master network card and a wireless terminal network card.

[0063] The first system module includes a first physical wireless network card and a first connection network card. The first system module is used to connect to the second system module through the first connection network card. The first physical wireless network card in the first system module is enumerated as a point-to-point group owner network card and a wireless terminal network card. That is, one physical wireless network card realizes the wireless transmission requirements in two modes. When the first physical wireless network card realizes the wireless transmission requirements in two modes, the network node identities are virtually the point-to-point group owner network card and the wireless terminal network card at the data level. Among them, the point-to-point group owner network card is used to establish a wireless connection with other wireless terminal devices, and the wireless terminal network card operates in the STA working mode and is used to connect the first system module to an external WiFi hotspot. It should be understood that the point-to-point group owner network card and the wireless terminal network card are defined according to the working mode and working state configuration of the physical wireless network card in the related technology, and are used to implement P2P communication and STA communication respectively. When the specific corresponding working mode and working state are the same, for example, other definition methods such as the point-to-point group owner port and the wireless terminal port have the same meaning.

[0064] Point-to-point direct connection means that based on the Wi-Fi Direct standard, devices in the WiFi wireless network can be connected to each other in a point-to-point form without passing through a wireless router. In the point-to-point direct connection based on the Wi-Fi Direct standard, the two devices are not completely equal node roles, but one is a P2P Group Owner, that is, a point-to-point group owner (also known as GO). In the embodiments of the present application, the wireless network card in the device acting as the point-to-point group owner is defined as the point-to-point group owner network card, and can also be defined as the P2P-GO network card, which operates in the P2P working mode; the other is a P2P Group Client, that is, a point-to-point client (also known as GC) relative to the point-to-point group owner network card. In the related technology, the scheme for implementing point-to-point direct connection may be that multiple devices negotiate and confirm the point-to-point group owner. In the embodiments of the present application, for the management of the local area network based on the bridging network card, the development and design of wireless terminal devices are simplified, and the first physical wireless network card in the first system module is directly enumerated as the point-to-point group owner network card.

[0065] The communication between the first system module and the second system module can be specifically realized through wired communication or wireless communication. The wired communication can specifically be a physical wired network card interface or a virtual network card interface based on a bus. The virtual network card interface based on a bus is, for example, a virtual network card interface based on USB (Universal Serial Bus). The wireless communication interface is, for example, a second physical wireless network card interface. The second physical wireless network card interface corresponds to the second physical wireless network card. The second physical wireless network card can be the same as the first physical wireless network card, and the main difference between the two is in the connection object and the action link.

[0066] Step S120: When it is detected that the second system module is connected, configure the IP addresses of the point-to-point group master network card, the first connection network card, and the second system module, so that the IP address of the first connection network card and the IP address of the second system module are in the same network segment, and the IP address of the first connection network card and the IP address of the point-to-point group master network card are in different network segments.

[0067] In an all-in-one computer, there are usually two system modules. The system module can be an OPS mini computer, which is an open pluggable computer module and is connected to the whole machine system through a pluggable interface. The power supply can be an external power supply or the power supply provided by the whole machine system of the all-in-one computer. The operating systems corresponding to the system modules can be the same or different. In the specific implementation process, to provide more comprehensive and rich functions and integrate the advantages of various operating systems, system modules with different operating systems are more often selected. Figure 4 In the exemplary network architecture shown, different operating systems are adopted.

[0068] In Figure 4 In the exemplary network architecture shown, the first system module 11 is an Android system module, and the second system module 12 is a Windows system module. It should be understood that when two different system modules are adopted, either of the two system modules can be used as the first system module 11, and the other as the second system module 12. It should be understood that the all-in-one computer 10 and the hardware configurations of the first system module 11 and the second system module 12 together meet various hardware conditions for the normal operation of the first system module 11 and the second system module 12, especially the necessary wired and wireless network hardware. The hardware provided for the system modules in the all-in-one computer 10 also has corresponding interfaces. After the first system module 11 and the second system module 12 are inserted into the all-in-one computer 10, they can establish a connection through the interfaces and normally drive the corresponding hardware to implement the corresponding functions. The hardware layout and connection in various devices provided in accordance with the design concept of the system module can adopt the implementation methods in related technologies, and the details of specific hardware configurations, connection interfaces, etc. are not limited herein.

[0069] In the same electronic device (exemplarily illustrated by an all-in-one computer) where two system modules are installed simultaneously, the interfaces configured in the all-in-one computer can enable communication between the two system modules. In the embodiments of this application, the port in the first system module used to implement communication with the second system module is defined as the first connection network card. Only when the first system module detects the second system module is it necessary to configure the IP addresses of the point-to-point group master network card, the first connection network card, and the second system module. During specific configuration, the IP address of the first connection network card and the IP address of the second system module are in the same network segment, that is, in the same local area network; the IP address of the first connection network card and the IP address of the point-to-point group master network card are in different network segments, that is, the IP address of the second system module and the IP address of the point-to-point group master network card are also in different network segments, which means the point-to-point group master network card, the first connection network card, and the second system module are in different local area networks. The second system module is connected to the first system module through the second connection network card. Here, the statement that the IP address of the first connection network card and the IP address of the second system module are in the same network segment specifically means that the IP address of the first connection network card and the IP address of the second connection network card in the second system module are in the same network segment.

[0070] In the specific implementation process, it is also possible that only one system module is installed inside the all-in-one computer. In this case, it is impossible to detect the second system module through the first connection network card, and the subsequent processing process can be terminated accordingly, and the network initialization process of the system module in the all-in-one computer in the related technology can be followed for processing.

[0071] In the case where the second system module is not detected, it is also possible to maintain the enumeration of the first physical wireless network card in step S110 and configure the wireless terminal network card to the STA working mode; after enumerating the first physical wireless network card as the point-to-point group master network card and the wireless terminal network card, when the second system module is not detected to be connected, a second NAT connection can be established between the point-to-point group master network card and the wireless terminal network card. This is equivalent to realizing the network connection of the all-in-one computer through the first system module while continuing to maintain the initialization state in step S110. It avoids the rollback of the initialization process and improves the speed of establishing the network connection.

[0072] When configuring the IP addresses of the bridging network card, the second system module (and subsequent connected wireless terminal devices), there are also other basic network information configurations such as the gateway address. Specific configurations can be made with reference to relevant network configuration methods. When implementing the embodiments of this application, there are strict configuration principles for the configuration of the network information of network nodes. The network connection established based on the configuration principles is also the basis for subsequent sending of network data packets to achieve the intended design effect of this solution.

[0073] Step S130: When a network data packet with a destination address being the IP address of the point-to-point group master network card and a port number being the first port number is received from a wireless terminal device through a wireless connection between the point-to-point group master network card and the wireless terminal device, the network data packet is distributed to the first screen mirroring application installed in the first system module for processing.

[0074] Step S140: When a network data packet with a destination address being the IP address of the point-to-point group master network card and a port number being the second port number is received from a wireless terminal device through a wireless connection, the destination address of the network data packet is modified to the IP address of the second system module, and the network data packet is forwarded to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and processed by the second screen mirroring application installed in the second system module.

[0075] In the embodiment of the present application, the all-in-one machine mainly performs data transmission with the wireless terminal device. When establishing a wireless connection between the wireless terminal device and the all-in-one machine, role negotiation in the point-to-point direct connection process is not performed. Instead, the wireless terminal device is directly used as a point-to-point client to establish a connection. The configuration process in the specific connection is basically the same as the configuration principle in the relevant access local area network. Only under this configuration principle can the subsequent data transmission process be realized, and no specific elaboration is made here. Of course, the wireless terminal device can also use the point-to-point group master network card as a hotspot, and the wireless module in the wireless terminal device acts as an STA to achieve the connection.

[0076] After establishing a network connection, network management of the local area network is implemented based on the network information configured above. Specifically, the first system module distributes the received network data packets, and the distribution criterion is the port information carried in the network data packets. The port information specifically refers to the port in the logical sense, and different ports usually correspond to different processing logics or applications for processing. In the embodiment of the present application, when the wireless terminal device performs screen mirroring, it can select a screen mirroring target from the first system module and the second system module. The network data packets corresponding to the two screen mirroring targets are both targeted at the point-to-point group master network card for sending. The difference between the screen mirroring targets is not distinguished by the hardware IP address in the network data packets, but by the port number. The screen mirroring application installed in the first system module is defined as the first screen mirroring application, and the screen mirroring application installed in the second system module is defined as the second screen mirroring application. In the case of clarifying the screen mirroring target through the target selection operation, the screen mirroring application installed in the wireless terminal device can add the first port number or the second port number to the network data packets generated based on screen mirroring according to the port numbers corresponding to different screen mirroring targets configured in advance. For the network data packets received by the point-to-point group master network card, they can be divided into two types according to the port number. The first type is the network data packets with the port number being the first port number, which need to be processed by the first screen mirroring application in the first system module. These can be directly distributed to the first screen mirroring application for parsing and processing, and this is also the network data packets when the user selects the first system module as the screen mirroring target. The second type is the network data packets with the port number being the second port number. At this time, the first system module modifies the target address of the network data packets to the IP address of the second system module, and forwards the network data packets to the first connection network card, so that the network data packets are sent to the second system module through the first connection network card and are processed by the second screen mirroring application installed in the second system module. Through the above processing strategy, the user only needs to select the all-in-one machine to be connected on the wireless terminal device, and then select the screen mirroring target when there is a need for screen mirroring transmission, and can send the network data packets for screen mirroring to the screen mirroring application in any specified system module for processing without switching the connection target. The first system module is equivalent to reconstructing a dedicated port mapping transmission path for screen mirroring data between the point-to-point group master network card and the first connection network card, thereby realizing flexible transmission of network data packets across the local area network based on point-to-point direct connection.

[0077] The network architecture established between the wireless terminal device 20 and the all-in-one machine 10 implemented based on the embodiment of the present application is as Figure 4As shown in the figure. The all-in-one computer 10 is equipped with two system modules that fully implement the embodiments of the present application and corresponding hardware configurations. Among them, the first system module 11 based on the Android operating system includes at least one physical wireless network card (not labeled in the figure, named the first physical wireless network card) and one physical wired network card (i.e., the first network card 111). The second system module 12 based on the Windows operating system includes at least one physical wired network card (i.e., the second network card 121). The first network card 111 and the second network card 121 are used to implement the internal network connection between the first system module 11 and the second system module 12. The first network card 111 is the first connection network card corresponding to the first system module 11. Of course, the first system module 11 and the second system module 12 can also be configured with other hardware to achieve various required communication connections. For example, the second system module 12 can also include a second physical wireless network card 122 and other physical wired network cards for accessing the external network.

[0078] Based on the above hardware configuration, when the all-in-one computer 10 is powered on, the first physical wireless network card is enumerated as the point-to-point group master network card P2P-GO and the wireless terminal network card wlan0. If it is further monitored that the first network card 111 is connected to the second network card 121, the IP address is configured as described above.

[0079] When statically defining a port mapping between the point-to-point group master network card P2P-GO and the first network card 111 for subsequent transmission of network data packets, a first NAT connection can also be established between the point-to-point group master network card and the first connection network card. Through the first NAT connection, the overall external Internet communication of the electronic device with the first system module and the second system module can be achieved. Specifically, when the first system module receives a network data packet with a destination address other than the IP address of the point-to-point group master network card from a wireless terminal device through a wireless connection, the network data packet is sent to the first connection network card through the first NAT connection, so that the wireless terminal device can access the Internet through the second system module. Based on the first NAT connection, in addition to being able to send screen mirroring data to the first device, the wireless terminal device can also achieve external Internet communication through the electronic device based on the first NAT connection. This type of network data packet is mainly a network data packet when directly accessing an external website or sending a shared file to the all-in-one computer 10.

[0080] The user can send network data packets through the wireless terminal device 20, and can also trigger the selection control to pop up a menu to select the sending target. For example, before the screen mirroring process, the screen mirroring target is selected as the first system module 11. The wireless terminal device 20 correspondingly adds the first port number corresponding to the first system module 11 when generating the network data packet. Thus, after the peer-to-peer group master network card P2P-GO receives the network data packet, it is distributed to the first screen mirroring application in the first system module 11 according to the first port number to realize the display of the screen mirroring picture. Each system module may have a more intuitive representation in the menu, such as "Android system" or "Windows system", etc.

[0081] In the specific implementation process, the user can also not select the screen mirroring target but directly confirm the screen mirroring. At this time, the port number in the generated network data packet is neither the first port number nor the second port number, and only indicates that the network data packet is used for screen mirroring. For the peer-to-peer group master network card, when receiving a network data packet with the target address being the IP address of the peer-to-peer group master network card and the port number not being the first port number or the second port number through wireless connection from the wireless terminal device, the network data packet is sent to the preset default screen mirroring application for processing, and the default screen mirroring application is one of the first screen mirroring application and the second screen mirroring application. For the network data packet generated by the quick screen mirroring operation where the user does not select the screen mirroring target, it can be directly processed by the preset default screen mirroring application to realize quick screen mirroring.

[0082] In the case where the second system module is not detected, after establishing the second NAT connection between the peer-to-peer group master network card and the wireless terminal network card, when receiving a network data packet with the target address not being the IP address of the peer-to-peer group master network card through wireless connection from the wireless terminal device, the network data packet is sent to the wireless terminal network card through the second NAT connection so that the wireless terminal device can access the Internet through the first system module. On the basis of establishing the second NAT connection between the peer-to-peer group master network card and the wireless terminal network card, the wireless terminal device can freely perform screen mirroring with the first system module and realize access to the external network. The wireless terminal device specifically based on the basic routing strategy of sending network data packets according to network information, and all network data packets are processed by the first system module, which will not be repeated here. Of course, at this time, it is still possible to directly perform screen mirroring to the first system module.

[0083] The above data transmission method is applied to the first system module. The first system module includes a first physical wireless network card and a first connection network card. The first system module is used to connect to the second system module through the first connection network card. The data transmission method includes: enumerating the first physical wireless network card as a point-to-point group master network card and a wireless terminal network card; when detecting the access of the second system module, configuring the IP addresses of the point-to-point group master network card, the first connection network card, and the second system module, so that the IP address of the first connection network card and the IP address of the second system module are in the same network segment, and the IP address of the first connection network card and the IP address of the point-to-point group master network card are in different network segments; when receiving, through the wireless connection between the point-to-point group master network card and the wireless terminal device, a network data packet with the destination address being the IP address of the point-to-point group master network card and the port number being the first port number, distributing the network data packet to the first screen mirroring application installed in the first system module for processing; when receiving, through the wireless connection, a network data packet with the destination address being the IP address of the point-to-point group master network card and the port number being the second port number, modifying the destination address of the network data packet to the IP address of the second system module, and forwarding the network data packet to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and is processed by the second screen mirroring application installed in the second system module. The first system module enumerates the first physical wireless network card as a point-to-point group master network card and a wireless terminal network card, configures the first connection network card and the second system module in the same network segment, configures the point-to-point group master network card and the first connection network card in different network segments, and establishes a data distribution mechanism based on port mapping between the point-to-point group master network card and the first connection network card. When receiving, through the point-to-point group master network card, a network data packet with the destination address being the IP address of the point-to-point group master network card and the port number being the first port number, distributing the network data packet to the first screen mirroring application installed in the first system module for processing. When receiving, through the point-to-point group master network card, a network data packet with the destination address being the IP address of the point-to-point group master network card and the port number being the second port number, modifying the destination address of the network data packet to the IP address of the second system module, and forwarding the network data packet to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and is processed by the second screen mirroring application installed in the second system module. After the wireless terminal device establishes a wireless connection with the first system module, it can quickly send network data packets to any system for processing. This solution only needs to set one wireless network card in the electronic device to meet the requirement that the wireless terminal device can switch the local area network transmission with any system module at any time, and at the same time meet the requirement that the wireless terminal device accesses the Internet through the electronic device, simplifies the connection operation of repeatedly connecting devices in the data transmission process, has low hardware cost, is simple and convenient to operate, and improves the continuity of data and the connection stability in the data transmission process.

[0084] The embodiment of the present application further provides a data transmission method applied to a wireless terminal device. Specifically, the process of implementing the data transmission method is described from the perspective of the wireless terminal device. For the detailed description of data processing and data transfer between the wireless terminal device and the first system module, reference can be made to the data transmission method applied to the first system module in the foregoing text, which will not be elaborated here. Only the overall implementation process of the data transmission method applied to the wireless terminal device is described. The wireless terminal device is wirelessly connected to an electronic device, which includes a first system module and a second system module, wherein the first system module realizes the wireless connection between the electronic device and the wireless terminal device. As Figure 5 shown, the data transmission method applied to the wireless terminal device includes:

[0085] Step S210: Receive a target selection operation acting on the screen mirroring target selection window, where the screen mirroring target selection window displays a first selection control corresponding to the first system module and a second selection control corresponding to the second system module.

[0086] Step S220: According to the target selection operation, obtain the current display screen as the screen mirroring screen, and generate a network data packet with the IP address of the first system module as the target address and the first port number corresponding to the first system module or the second port number corresponding to the second system module as the port number.

[0087] Step S230: Send the network data packet to the first system module, so that the first system module distributes the network data packet to the first screen mirroring application installed on the first system module for processing according to the first port number, or forwards the network data packet to the second system module according to the second port number, and the second screen mirroring application installed on the second system module processes it.

[0088] Based on the above embodiment, the data transmission method further includes:

[0089] When receiving a quick screen mirroring operation, obtain the current display screen as the screen mirroring screen, and generate a network data packet with the IP address of the first system module as the target address and without configuring a port;

[0090] Send the network data packet to the first system module, so that the first system module sends the network data packet to a preset default screen mirroring application for processing, and the default screen mirroring application is one of the first screen mirroring application and the second screen mirroring application.

[0091] The first system module enumerates the first physical wireless network card as a point-to-point group master network card and a wireless terminal network card, configures the first connection network card and the second system module in the same network segment, configures the point-to-point group master network card and the first connection network card in different network segments, and establishes a data distribution mechanism based on port mapping between the point-to-point group master network card and the first connection network card. When a network data packet with a destination address of the IP address of the point-to-point group master network card and a port number of the first port number is received from a wireless terminal device through the point-to-point group master network card, the network data packet is distributed to the first screen mirroring application installed in the first system module for processing. When a network data packet with a destination address of the IP address of the point-to-point group master network card and a port number of the second port number is received from a wireless terminal device through the point-to-point group master network card, the destination address of the network data packet is modified to the IP address of the second system module, and the network data packet is forwarded to the first connection network card, so that the network data packet is sent to the second system module through the first connection network card and processed by the second screen mirroring application installed in the second system module. After the wireless terminal device establishes a wireless connection with the first system module, it can quickly send network data packets to any system for processing. This solution only needs to set a wireless network card in the electronic device to meet the requirement of the wireless terminal device to switch the local area network transmission with any system module at any time, and at the same time meet the requirement of the wireless terminal device to access the Internet through the electronic device, simplifies the connection operation of repeatedly connecting devices during the data transmission process, has low hardware cost, is simple and convenient to operate, and improves the continuity of data and the connection stability during the data transmission process.
