Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication connection, and in particular, to a local area network device connection method, a storage medium, and an electronic device. Background Art

[0002] With the rapid development of Internet of Things technology, more and more network devices need to achieve network communication within the same local area network. In related technologies, in a conference scenario, a conference host device and several controlled devices are deployed in a conference room. Users usually need to connect an external display screen and mouse to the conference host device to control the conference host device, which is inconvenient to operate. When the external devices such as the display screen and mouse and the controlled devices communicate with the conference host device by accessing the local area network where the conference host device is located, the IP address (Internet Protocol Address) of the opposite conference host device is usually recorded as a communication bridge.

[0003] However, if the IP of the other end conference host device cannot be accessed due to changes in the network environment, the communication control is interrupted and re-pairing is required. The relevant pairing method requires a public pairing code, which the user memorizes and then enters manually. The public pairing code method is not very secure, and the manual pairing code entry method is very inconvenient. Summary of the invention

[0004] In order to overcome the problems existing in the related art, the present application provides a local area network device connection method, a storage medium and an electronic device. When the IP address of the conference host device changes, the conference device automatically re-establishes the connection with the conference host device, thereby improving the security and convenience of reconnection.

[0005] According to a first aspect of an embodiment of the present application, a method for connecting a local area network device is provided, comprising the following steps:

[0006] The conference device sends a connection check instruction to the conference host device based on the pre-established first control communication channel;

[0007] If the connection check response instruction is not received within the first preset time, the conference device connects to the local area network where the conference host device is located, and broadcasts the business service request information in the local area network;

[0008] If it is determined according to the business service request information that the conference host device has the corresponding business service, the conference host device sends a second device response information to the conference device via the local area network;

[0009] The conference device obtains the second device response information received within a second preset time, and sends the stored first access token information to the conference host device based on the second device response information;

[0010] If the conference host device determines that the received first access token information is the same as the pre-stored second access token information, the conference device establishes a second control communication channel with the conference host device;

[0011] The conference device and the conference host device exchange control data based on the second control communication channel.

[0012] According to a second aspect of an embodiment of the present application, a local area network device connection method is provided, including:

[0013] Sending a connection check instruction to the conference host device based on a pre-established first control communication channel;

[0014] If the connection check response instruction is not received within the first preset time, connecting to the local area network where the conference host device is located, and broadcasting the business service request information in the local area network;

[0015] If it is determined according to the business service request information that the conference host device has the corresponding business service, obtaining the second device response information sent by the conference host device within a second preset time, and sending the stored first access token information to the conference host device based on the second device response information;

[0016] If the first access token information is identical to the second access token information pre-stored by the conference host device, establishing a second control communication channel with the conference host device;

[0017] Control data interaction is performed with the conference host device based on the second control communication channel.

[0018] According to a third aspect of an embodiment of the present application, there is provided an electronic device, comprising a processor and a memory; the memory stores a computer program, and the computer program is suitable for being loaded by the processor and executing the local area network device connection method as described above.

[0019] According to a fourth aspect of an embodiment of the present application, a computer-readable storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the local area network device connection method as described above is implemented.

[0020] The conference device of the embodiment of the present application sends a connection check instruction to the conference host device based on a pre-established first control communication channel; if the connection check response instruction of the conference host device is not received within the first preset time, the conference device connects to the local area network where the conference host device is located, and broadcasts business service request information in the local area network; if it is determined according to the business service request information that the conference host device has the corresponding business service, the conference host device sends second device response information to the conference device through the local area network; based on the second device response information, the conference device sends the stored first access token information to the conference host device; if the conference host device determines that the received first access token information is the same as the pre-stored second access token information, the conference device establishes a second control communication channel with the conference host device; the conference device and the conference host device exchange control data based on the second control communication channel. In the embodiment of the present application, when the conference device is unable to exchange data with the conference host device through the pre-established first control communication channel because the IP address of the conference host device has changed, the conference device automatically broadcasts the business service request information and verifies the first access token information, and then automatically re-establishes the connection with the conference host device without disclosing the pairing code or the user remembering the pairing code for manual input, thereby improving the security and convenience of device reconnection.

[0040] The LAN device connection method of the embodiment of the present application can be applied to education scenarios, conference scenarios, and other scenarios. The following is an exemplary description using the application in a conference scenario as an example.

[0041] See also Figure 1 , which is a schematic diagram of an application scenario of the LAN device connection method shown in an embodiment of the present application. The application scenario of the LAN device connection method of the embodiment of the present application includes a conference host device 10, a conference device 20 and a router 30. In the embodiment of the present application, the conference device 20 includes a conference touch device 21 and a plurality of controlled devices 22.

[0042] The conference host device 10 can also be called a central host or a projection box, etc. The conference host device 10 is used to realize the centralized management of the conference room network devices, and the conference host device 10 receives the control data of the conference touch device 21 to realize the centralized control of several controlled devices 22.

[0043] Specifically, the conference host device 10 sends the host operation interface data to the conference touch control device 21 through the local area network; the conference touch control device 21 displays the host operation interface according to the host operation interface data, and the conference touch control device 21 responds to the touch command of the host operation interface and sends the touch command to the conference host device 10. The conference host device 10 performs data processing or sends corresponding control commands to the corresponding controlled device based on the touch command to realize control of the controlled device.

[0044] Among them, the conference touch device 21 is used to control the conference host device 10. It can be understood that the conference touch device 21 includes at least one display screen. Specifically, the conference touch device 21 is configured with a display screen with a touch function. From the technical principle, the display screen can be a capacitive screen, a resistive screen, an electromagnetic screen, an infrared screen, and a surface acoustic wave screen. The user can implement touch operation by touching the display screen with a finger or a stylus. Correspondingly, the conference touch device 21 detects the touch position, and determines a response scheme according to the display content corresponding to the touch position, and then responds to implement the touch function. The conference touch device 21 can be a computer device such as a mobile phone or an interactive tablet. The conference touch device 21 can establish a connection with the conference host device 10 through a local area network connected to the conference host device 10.

[0045] The controlled device 22 is used to realize the intelligence of the conference room. The controlled device 22 may include a camera, a microphone, a light, and other devices. The controlled device 22 may establish a connection with the conference host device 10 through a connection interface plugged into the conference host device 10, or the controlled device 22 may establish a connection with the conference host device 10 through a local area network connected to the conference host device 10.

[0046] The router 30 is used to connect the conference host device 10 and the conference touch device 21 and the conference host device 10 and the controlled device 22 in the local area network, and serves as a data bridge between the conference host device 10 and the conference touch device 21 and the conference host device 10 and the controlled device 22.

[0047] The following will be combined with the attached Figures 2 to 9 , the LAN device connection method provided in the embodiment of the present application is introduced in detail.

[0048] See also Figure 2 and Figure 3 The local area network device connection method provided in the embodiment of the present application includes the following steps:

[0049] Step S101: the conference device sends a connection check instruction to the conference host device based on a pre-established first control communication channel.

[0050] Among them, the first control communication channel is the channel when the conference device and the conference host device can transmit control data normally before the current time. The channel can be a communication channel implemented based on protocols such as TCP, UDP or HTTP. The communication channel implemented based on protocols such as TCP, UDP or HTTP usually requires knowing the IP address and port number of the other party.

[0051] In a LAN environment, the IP address of a device is generally assigned dynamically and cannot be guaranteed to have the same IP address every time for the same device in the same LAN segment. Therefore, when the IP address of a conference host device in the LAN changes, the conference device can no longer control data transmission through the first control communication channel established previously.

[0052] Therefore, in order to achieve effective transmission of control data and avoid the situation where the conference host device fails to transmit control data through the first control communication channel due to a change in the IP address after the conference device sends the control data, causing the user to wait for a long time, before the conference device and the conference host device transmit control data, the conference device sends a connection check instruction to the conference host device based on the pre-established first control communication channel to determine whether control data can be transmitted with the conference host device through the first control communication channel.

[0053] The connection check instruction may be any instruction for detecting whether control data transmission can be performed with the conference host device through the first control communication channel, such as a ping instruction or a heartbeat check instruction, etc. The present application does not limit its specific form.

[0054] Step S102: If the connection check response instruction is not received within the first preset time, the conference device connects to the local area network where the conference host device is located, and broadcasts the business service request information in the local area network.

[0055] If the connection check response instruction of the conference host device is not received within the first preset time, it means that the conference device cannot control data transmission with the conference host device through the first control communication channel. Therefore, the conference device will automatically discover the conference host device and re-establish the connection with the conference host device.

[0056] The conference device is connected to a router of the local area network where the conference host device is located, and then joins the local area network, thereby broadcasting the business service request information through the router in the local area network.

[0057] The business service request information is used to indicate the required business service; the business service request information may be a service name, a service type or a host name. The business service may be a file transfer protocol service, a projection service or a printing service, etc.

[0058] In an optional embodiment, the conference device generates business service request information by scanning the business service information of the conference host device, and then broadcasts the business service request information in the local area network.

[0059] In another optional embodiment, the conference device displays a business service input interface, receives business service information input by a user, and then generates business service request information, thereby broadcasting the business service request information in the local area network.

[0060] In another optional embodiment, when the conference device normally transmits control data with the conference host device based on the first control communication channel, the conference device will obtain and store the business information of the conference host device, and then generate business service request information, thereby broadcasting the business service request information in the local area network.

[0061] It is understandable that after the conference host device joins the local area network, the conference host device is connected to the router of the local area network, the conference host device sends the business service information it can provide to the router, and the router stores the business service information in the service list so that other devices can connect to the conference host device.

[0062] In an optional embodiment, after the conference host device joins the local area network, the conference host device will automatically generate a host name as business service information to uniquely identify the services it can provide in the local area network; after the conference host device sends the host name to the router, the router queries the local service list to detect whether the host name is repeated with other host names. If this host name exists, it means that other service providing devices in the network have already used this host name, and then the router sends a conflict response message to the conference host device, prompting the conference host device to regenerate a new host name and re-detect. If the conference host device does not receive a conflict response message within the detection time, it means that the host name can uniquely identify the host conference device in the local area network, thereby ensuring the uniqueness of the services provided by the conference host device, so that other devices can uniquely connect to the conference host device.

[0063] Among them, if a connection check response instruction from the conference host device is received within the first preset time, it means that the conference device can transmit control data with the conference host device through the first control communication channel. Therefore, the conference device will transmit control data with the conference host device through the first control communication channel.

[0064] Step S103: if it is determined according to the business service request information that the conference host device has the corresponding business service, the conference host device sends the second device response information to the conference device via the local area network.

[0065] In an optional embodiment, after receiving the business service request information, the router in the local area network parses the business service information, matches the business service information with the locally stored service list, determines the conference host device corresponding to the business service request information, and then sends information indicating that the conference host device has the corresponding business service to the conference host device, so that the conference host device sends the second device response information of the conference host device to the conference device via the local area network.

[0066] In another optional embodiment, after receiving the business service request information, the router in the local area network will forward the business service request information to all host devices in the local area network. Each host device will parse the business service request information to obtain the business service information, and match its own business service information with it to determine whether it has the business service. The host device that has the business service, i.e., the conference host device, will send the second device response information of the conference host device to the conference device via the local area network.

[0067] The second device response information is used to indicate the connection communication information of the conference host device, and the device response information includes but is not limited to the IP address and the connection port.

[0068] Step S104: the conference device obtains the second device response information received within the second preset time, and sends the stored first access token information to the conference host device based on the second device response information.

[0069] The first access token information (token) is used to indicate the type of data interaction that can be performed between the conference device and the conference host device.

[0070] Specifically, the first access token information can be a data interaction type credential between the conference device and the conference host device determined by the conference host device. When the conference device normally transmits control data with the conference host device based on the first control communication channel, the conference device will obtain and store the first access token information of the conference host device.

[0071] Step S105: if the conference host device determines that the received first access token information is the same as the pre-stored second access token information, the conference device establishes a second control communication channel with the conference host device.

[0072] It can be understood that the second access token information is a data interaction type credential determined by the conference host device and stored locally.

[0073] After receiving the first access token information, the conference host device compares the first access token information with the second access token information; if the two are the same, it means that the data interaction types between the conference device and the conference host device match each other, and a new second control communication channel can be established to realize data interaction; if the two are not the same, it means that the data interaction types between the conference device and the conference host device match each other, and a new second control communication channel cannot be established, and re-detection and matching are required.

[0074] If the conference device does not receive the second device response information within the second preset time, it means that the conference host device may be turned off or not connected to the local area network, and the conference device displays a prompt message that the conference host device is lost.

[0075] It should be understood that different conference devices correspond to different second control communication channels. Specifically, when the conference device includes a conference touch device and several controlled devices, the conference touch device and the several controlled devices will correspond to different second control communication channels to interact with the conference host device for control data.

[0076] Step S106: the conference device and the conference host device exchange control data based on the second control communication channel.

[0077] The conference device sends touch data to the conference host device, and the conference host device receives the touch data for control processing.

[0078] The conference device of the embodiment of the present application sends a connection check instruction to the conference host device based on the pre-established first control communication channel; if the connection check response instruction of the conference host device is not received within the first preset time, the conference device connects to the local area network where the conference host device is located, and broadcasts the business service request information in the local area network; if it is determined according to the business service request information that the conference host device has the corresponding business service, the conference host device sends the second device response information to the conference device through the local area network; based on the second device response information, the conference device sends the stored first access token information to the conference host device; if the conference host device determines that the received first access token information is the same as the pre-stored second access token information, the conference device establishes a second control communication channel with the conference host device; the conference device and the conference host device control data interaction based on the second control communication channel. In the embodiment of the present application, when the conference device cannot interact with the conference host device through the pre-established first control communication channel because the IP address of the conference host device changes, the conference device automatically broadcasts the business service request information and verifies the first access token information, and then automatically re-establishes the connection with the conference host device, without the need to disclose the pairing code, and the user does not need to remember the pairing code for manual input, thereby improving the security and convenience of device reconnection.

[0079] See also Figure 4 and Figure 5 In an optional embodiment, before the step of sending a connection check instruction to the conference host device based on the pre-established first control communication channel in step S101, the following steps are included:

[0080] Step S1011: The conference device connects to the local area network where the conference host device is located, and broadcasts the business service request information in the local area network.

[0081] Step S1012: if it is determined according to the first business service request information that the conference host device has the corresponding business service, the conference host device sends the first device response information to the conference device via the local area network.

[0082] Step S1013: the conference device establishes a first control communication channel with the conference host device according to the first access token information determined by the conference host device.

[0083] Among them, the method of step S1011 to step S1012 is the same as that of step S102 to step S103. For details, please refer to the description of step S102 to step S103, and this application will not elaborate on it.

[0084] The step S1013 is described in detail below:

[0085] See also Figure 6 In one embodiment, the step of establishing a first control communication channel with the conference host device according to the first access token information determined by the conference host device in step S1013 includes:

[0086] Step S11311: the conference device sends an access token request to the conference host device.

[0087] The access token request may include a device identifier of the conference device to uniquely identify the conference device in the local area network.

[0088] Step S11312: the conference host device sends the first access token information to the conference device in response to the trigger operation of confirming access.

[0089] After receiving the access token request, the conference host device will parse the access token request to obtain the device identification of the conference device, inform the user of the device identification, and the user inputs the operation of confirming the access, and the conference host device sends the first access token information to the conference device. It can be understood that the conference host device can inform the user of the identification by voice, and correspondingly, the operation of the user inputting the confirmation of the access can be confirmed by the conference host device parsing the user's voice.

[0090] Step S11313: The conference device receives the first access token information and establishes a first control communication channel with the conference host device.

[0091] In the embodiment of the present application, after the conference host device sends the first access token information for confirmation, the first control communication channel is established, which can improve the security and reliability of control data interaction between the conference device and the conference host device based on the first control communication channel.

[0092] See also Figure 7 In another embodiment, in step S1013, the step of establishing a first control communication channel with the conference host device according to the first access token information determined by the conference host device includes:

[0093] Step S11321: the conference device receives the first access token information input by the user, and sends the first access token information to the conference host device.

[0094] The conference host device determines the second access token information and generates an access token QR code, and the conference device obtains the first access token information by scanning the access token QR code. Alternatively, the conference device displays an access token input interface, receives the access token information input by the user, and obtains the first access token information.

[0095] Step S11322: If the conference host device determines that the received first access token information is the same as the pre-stored second access token information, the conference device establishes a first control communication channel with the conference host device.

[0096] The conference device of the embodiment of the present application receives the first access token information input by the user and sends it to the conference host device. The conference host device matches the received first access token information with the pre-stored second access token information, which can reduce the conference host device's notification and confirmation operations. After the received first access token information matches the pre-stored second access token information, a first control communication channel is established, which can improve the security and reliability of control data interaction between the conference device and the conference host device based on the first control communication channel.

[0097] In an optional embodiment, the LAN device connection method further includes the following steps:

[0098] Step S107: The conference device sends a session message request to the conference host device through the web real-time communication technology based on the local area network.

[0099] Among them, the session message request implemented in the present application is a proposed session message based on SDP (Session Description Protocol), and the session message request includes the media stream that the conference device wants to use.

[0100] Step S108: the conference host device sends session message response information according to the session message request.

[0101] If the conference host device receives a proposed session request, it generates a session message response that it can receive based on the received session message request and the session that it can provide. It can be understood that the session message response information of the embodiment of the present application is a response session based on SDP, and the session message response information includes a matching stream for each media stream in the proposed session to indicate whether the media stream is accepted.

[0102] Step S109: the conference device sends the device information of the conference device and the host device information of the conference host device according to the session message response information.

[0103] It can be understood that the touch device information includes the IP address and port information of the conference device; the host device information includes the IP address and port information of the conference host device.

[0104] Step S110: Based on the touch device information and the host device information, the conference device and the conference host device establish a media data channel.

[0105] Step S111: the conference device and the conference host device interact with each other over the media data channel.

[0106] The embodiment of the present application establishes a media data channel based on session messages, which can achieve the accuracy of media data interaction.

[0107] See also Figure 8 In an optional embodiment, the conference device includes a conference touch device; the step of exchanging data between the conference device and the conference host device based on the second control communication channel in step S105 includes:

[0108] Step S10511: the conference host device sends the host operation interface data to the conference touch device based on the second control communication channel.

[0109] Step S10512: the conference touch control device displays the host operation interface according to the host operation interface data. The conference touch control device responds to the touch control instruction for the host operation interface and sends the touch control instruction to the conference host device to process the host operation interface.

[0110] The conference touch device of the embodiment of the present application is a small-screen mobile touch device to facilitate users to control the conference host device. The embodiment of the present application can control the conference host device without additionally connecting a display screen and a mouse, which greatly facilitates users to connect and control the conference host device.

[0111] See also Fig. 9 In an optional embodiment, the conference device includes a plurality of controlled devices; the step of the conference device and the conference host device performing control data interaction based on the second control communication channel in step S105 includes:

[0112] Step S10521: the conference host device sends the control data to the corresponding controlled device based on the second control communication channel.

[0113] Step S10522: The controlled device executes the corresponding function according to the control data.

[0114] The controlled device and the conference host device in the embodiment of the present application realize the interaction of control data through the second control communication channel established by the local area network. Compared with the wired connection between the controlled device and the conference host device, the connection method is convenient and the space occupied by the line is reduced.

[0115] In an optional embodiment, the conference host device includes a plurality of device connection ports; a plurality of controlled devices are respectively plugged into the corresponding device connection ports to perform data exchange with the conference host device.

[0116] In the embodiment of the present application, a plurality of device connection ports are set on the conference host device, so that a plurality of controlled devices can be plugged into the corresponding device connection ports, thereby ensuring accurate and fast data interaction between the controlled devices and the conference host device when the conference host device and the controlled devices cannot establish a connection through a local area network.

[0117] See also Fig.10 , which is a flow chart of a local area network device connection method shown in the second embodiment of the present application. The local area network device connection method of the embodiment of the present application includes the following steps:
