Description

[0002] During screen transmission between a sending terminal device such as a notebook computer and a display terminal device such as an interactive smart panel, the sending terminal and the display terminal are generally directly connected. That is, the sending terminal directly establishes a wireless connection with the display terminal using the AP (Wireless Access Point) of the display terminal.

[0003] When the sending terminal connects to the AP of the sending terminal, the SSID (Service Set Identifier) and password of the AP are automatically memorized. Since the SSID and password of the AP of the same display terminal are generally fixed, the sending terminal will automatically connect to the AP of the sending terminal when it enters the range of the AP next time, regardless of whether it needs to be connected.

[0004] In order to prevent the sending terminal from being connected by mistake, the password of the AP of the display terminal is updated and the like. However, the sending terminal needs to be paired again when it needs to be connected to the AP next time, which is troublesome. Therefore, in the prior art, the password of the AP is edited into the name of the AP in the form of a field, and the sending terminal parses the name of the AP to obtain the password of the AP, thereby solving the problem of pairing again.

[0048] It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

[0049] With reference to Figure 1 The application discloses a wireless screen transmission connection method, and an execution subject is a sending end.

[0050] S101, the sending end acquires a screen transmission code, the screen transmission code uniquely corresponds to a display end;

[0051] S102, the screen transmission code is sent to a server to acquire an IP address corresponding to the screen transmission code and fed back by the server, the IP address is an IP address of the display end, and a mapping relationship between the screen transmission code and the IP address is stored in the server; and

[0052] S103, AP information of the display end is acquired according to the screen transmission code, the AP information includes a service set identifier (SSID) and a password of the display end;

[0053] S104, a wireless connection with the display end is established according to the AP information;

[0054] S105, a screen transmission connection with the display end is established according to the IP address.

[0055] As described in the above step S101, the execution subject of the embodiment is the sending end, the sending end refers to a computer device with a screen and a wireless connection function, such as a computer, a notebook computer, a smart phone, a tablet computer and the like, and the computer device is installed with a screen transmission software. The display end refers to a smart whiteboard device such as an interactive all-in-one machine, and the smart whiteboard device takes a high-definition liquid crystal screen as a display and operation platform, and has functions of writing, annotation, drawing, synchronous interaction, multimedia entertainment, network conference integration and the like, and integrates technologies of high-definition display, human-computer interaction, multimedia information processing and network transmission. The screen transmission code is identification information, and has uniqueness, and in the disclosure, each screen transmission code uniquely corresponds to a display end. It should be noted that each screen transmission code uniquely corresponds to a display end refers to that in the same network environment, different display ends in the same network environment correspond to different screen transmission codes.

[0056] The screen transmission code acquisition mode of the sending end includes multiple modes, such as automatic acquisition or manual input and the like. The automatic acquisition mode is described in the subsequent related description, and is not described herein again. The manual input is that an operator of the sending end inputs a screen transmission code displayed on a screen of the display end into a screen transmission code input box provided by the sending end.

[0057] As described in the above step S102, the server is a server connected with the sending end and the display end through the network respectively, which can be a cloud server and the like, and pre-stores IP address and the like information of the sending end and a mapping relationship between the screen transmission code and the IP address. When the sending end sends the screen transmission code to the server, the server can quickly find the IP address corresponding to the screen transmission code based on the mapping relationship between the screen transmission code and the IP address.

[0058] As described in the above step S103, the sending end can also acquire the AP information of the display end based on the screen transmission code. Specifically, two implementation methods are included, as follows.

[0059] The first method is to send a broadcast request for acquiring the AP information of the display end according to the IP address, and receive the AP information fed back by the display end based on the broadcast request. In this method, the sending end sends a broadcast request, and then receives the AP information fed back by the display end. This method does not require the display end to upload the AP information to the server end, and the sharing of the AP information can be completed locally.

[0060] The second method is to receive the AP information fed back by the server based on the screen transmission code, and the server stores a mapping relationship between the screen transmission code and the AP information. In this method, the display end uploads its AP information to the server in advance for storage, and the storage is associated with the screen transmission code or the IP address. When the server receives the screen transmission code, the corresponding AP information can be found based on the screen transmission code, so that the AP information is directly fed back to the sending end, and the sending end can quickly acquire the AP information of the display end.

[0061] The above step S102 and step S103 can be executed sequentially or simultaneously.

[0062] As described in the above steps S104 and S105, the wireless connection with the display end is established through the AP information, and the screen transmission connection with the display end is implemented through the IP information and the built-in screen transmission software, which will not be described herein again.

[0063] In one embodiment, before the step S105 of establishing the screen transmission connection with the display end according to the IP address, the following steps are included.

[0064] S1051, acquiring a first signal strength of a signal received by a router and sent by the sending end, and a second signal strength of a signal received by the router and sent by the sending end; and,

[0065] S1052, acquiring a third signal strength of a signal received by the router and sent by the display end, and a fourth signal strength of a signal received by the router and sent by the display end; and,

[0066] S1053, acquire a fifth signal strength of the signal received by the sending end from the display end, and a sixth signal strength of the signal received by the display end from the sending end;

[0067] S1054, determine whether the first signal strength, the second signal strength, the third signal strength and the fourth signal strength are all greater than any one of the fifth signal strength and the sixth signal strength;

[0068] S1055, if yes, stop the wireless connection between the sending end and the display end according to the AP information, and switch to the wireless connection between the sending end and the display end through the router.

[0069] As described above, the signal strength of the received signal can be obtained when the terminals such as the router, the sending end and the display end interact with each other. In the present disclosure, in order to better complete the screen transmission connection between the sending end and the display end and reduce the occurrence of screen transmission lag and frame loss, the signal transmission path with better signal link is selected as much as possible. Therefore, before the step of establishing the screen transmission connection with the display end according to the IP address, it is determined whether the first signal strength, the second signal strength, the third signal strength and the fourth signal strength are all greater than any one of the fifth signal strength and the sixth signal strength. If yes, the wireless connection between the sending end and the display end according to the AP information is stopped, and the wireless connection between the sending end and the display end through the router is switched. That is to say, as long as the signal strength in any direction between the display end and the sending end is less than the signal strength in any direction between the sending end and the router, and less than the signal strength in any direction between the display end and the router, the connection path between the sending end and the display end needs to be switched, that is, the router is selected as a transfer bridge to connect the display end and the sending end. Otherwise, the direct connection mode between the sending end and the display end is continued.

[0070] The first signal strength, the second signal strength, the third signal strength and the fourth signal strength are usually historical signal strengths recorded when the sending end and the display end are connected to the network through the router before initiating screen transmission. In another embodiment, the sending end and the display end acquire the signal strengths based on the need to be temporarily connected to the router before establishing the screen transmission connection.

[0071] In one embodiment, the step S101 of acquiring the screen transmission code by the sending end includes:

[0072] S1011, the sending end scans a two-dimensional code on the display end;

[0073] S1012, the two-dimensional code is parsed to acquire the screen transmission code.

[0074] As described above, the screen transmission code is not a plaintext, but a two-dimensional code. After scanning and recognition, the sending end analyzes the screen transmission code corresponding to the two-dimensional code. The screen transmission code is obtained by scanning and analysis, without manual input by the user, thereby improving the acquisition speed of the screen transmission code and the user experience.

[0075] With reference to Figure 2 The application further discloses a wireless screen transmission connection method, and the execution subject is a server. The connection method comprises the following steps:

[0076] S201, the server receives a screen transmission code acquisition request of a display end, and the server stores IP address and AP information of the display end;

[0077] S202, the screen transmission code is generated based on the screen transmission code acquisition request, and the screen transmission code is sent to the display end;

[0078] S203, the screen transmission code uploaded by the sending end is received, and the IP address and AP information of the display end are sent to the sending end, so that the sending end establishes a wireless connection with the display end according to the AP information, and then establishes a screen transmission connection with the display end based on the IP address.

[0079] As described above, the server generates a screen transmission code based on a preset algorithm after receiving the screen transmission code acquisition request of the display end, and then sends the screen transmission code to the display end and establishes a mapping relationship between the screen transmission code and the IP address and AP information of the display end. When the screen transmission code uploaded by the sending end is received, the corresponding IP address and AP information of the display end can be quickly and accurately found according to the mapping relationship between the screen transmission code and the IP address and AP information of the display end, and the IP address and AP information are fed back to the sending end, so that the sending end establishes a wireless connection with the display end based on the IP address and AP information, and then establishes a screen transmission connection. In the application, the server plays a role of intermediate switching, so that the sending end can quickly and accurately realize wireless connection and screen transmission connection with the display end.

[0080] In one embodiment, before the step S201 of receiving the screen transmission code acquisition request of the display end by the server, the method further comprises the following steps:

[0081] S2011, the AP information uploaded by the display end is received, and the AP information is replaced with historical AP information corresponding to the display end.

[0082] As described above, in order to prevent the sending terminal from establishing an AP connection with the display terminal, the display terminal automatically updates the password in the AP information at intervals after automatically connecting with the AP of the display terminal when entering the AP wireless connection range of the display terminal. Therefore, when the password in the AP information of the display terminal is updated, the password is simultaneously updated in the server, so that the sending terminal can obtain the available password when needing to connect with the display terminal.

[0083] With reference to Figure 3 The application further discloses a wireless screen transmission connection method, and an execution subject is a display terminal, the connection method comprising the following steps.

[0084] S301, the display terminal triggers a screen transmission request.

[0085] S302, an acquisition screen transmission code request is sent to a server according to the screen transmission request.

[0086] S303, the screen transmission code issued by the server is received and displayed on a screen, so that a sending terminal obtains the screen transmission code, and establishes a wireless connection with the display terminal and a screen transmission connection with the display terminal based on the IP address and AP information of the display terminal obtained from the server based on the screen transmission code.

[0087] As described above in steps S301 to S303, after the display terminal is triggered by the screen transmission request, an acquisition screen transmission code request is sent to the server, the server generates a screen transmission code based on the acquisition screen transmission code request, and the generated screen transmission code is fed back to the display terminal, so that the display terminal displays the screen transmission code on the screen after receiving the screen transmission code. The screen transmission code can be displayed on the screen in the form of a two-dimensional code. Finally, the sending terminal obtains the corresponding IP address and AP information from the server based on the screen transmission code, and finally realizes the wireless connection and screen transmission connection with the display terminal.

[0088] In another embodiment, when the display terminal is triggered by the screen transmission request, the display terminal itself generates a screen transmission code, and then uploads the screen transmission code to the server, and establishes a mapping relationship with the IP address, SAP information and the like of the display terminal in the server.

[0089] In an embodiment, before the step S301 that the display terminal triggers the screen transmission request, the step S3011 comprises the following steps.

[0090] S3011, the AP information is updated, and the AP information is uploaded to the server, so that the server replaces the historical AP information corresponding to the display terminal with the AP information.

[0091] As described above, in order to prevent the sending terminal from establishing an over-AP connection with the display terminal, the display terminal automatically updates the password in the AP information at intervals after entering the AP wireless connection range of the display terminal. Therefore, when the password in the AP information of the display terminal is updated, the password is simultaneously updated in the server, so that when the sending terminal needs to connect to the display terminal, the available password can be obtained.
