As shown in fig. 2, in the first embodiment of the present application, the method for connecting a screen projection device of the present application when executed by the screen projection device includes the following steps:
step S210: and generating the equipment information of the screen projection equipment.
In this embodiment, the device information includes a temporary identification code and a temporary authentication code; the temporary identification code is used for judging consistency between the terminal equipment and the equipment identification of the screen projection equipment scanned by the terminal equipment, and the temporary authentication code is used for verifying authentication information sent by the screen projection equipment to the terminal equipment. The device identifier is a visible device name set when the screen projection device is scanned by the terminal device. For example, before the user performs screen projection on the information of the terminal device a, a "display" identifier set to be visible by the screen projection device B is scanned by the terminal device a, and the "display" is a device identifier. After the screen projection device generates the device information, the device information is written into the NFC data exchange module of the screen projection device, and a user can acquire the device information written into the NFC data exchange module by the screen projection device through the terminal device.
As shown in fig. 3, in the second embodiment of the present application, step S210 includes the steps of:
step S211: and acquiring a custom field for generating the identification code and the temporary authentication code.
In this embodiment, the screen projection device generates different random numbers by using a custom algorithm, such as a random number function, and randomly combines all the random numbers to obtain a custom field for generating the identification code and the temporary authentication code.
Step S212: and respectively selecting a first part of content and a second part of content from the custom field according to a preset rule.
In this embodiment, after the custom field is generated, the screen projection device may obtain the first part of content and the second part of content respectively by using a preset rule, for example, by equally dividing the custom field into two segments, or by randomly selecting two segments of content from the custom field. For example, the custom field is Screen @ # $ SD, and the custom field may be divided into two segments by equally dividing the custom field into two segments, so that the first part of content is Screen and the second part of content is @ # $ SD.
Step S213: determining the first part of content as the temporary identification code and the second part of content as the temporary authentication code.
In this embodiment, after the first part of content and the second part of content are respectively selected from the custom field, the first part of content is determined as the temporary identification code, and the second part of content is determined as the temporary authentication code. For example, if the content of the first part is Screen, the temporary identifier is Screen, and the content of the second part is @ # $ SD, the temporary authentication code is @ # $ SD.
Step S220: and when an information acquisition request sent by the terminal equipment is received, sending the equipment information to the terminal equipment.
In this embodiment, before a user performs screen projection on information of a terminal device through a screen projection device, the terminal device needs to establish screen projection connection with the screen projection device. Specifically, a user brings a terminal device close to the screen projection device, the terminal device sends an information acquisition request for acquiring device information to the terminal device, and after the screen projection device responds to the information acquisition request, the device information is sent to the terminal device through the NFC data exchange module, so that the terminal device receives the device information of the screen projection device through the NFC data reading module of the terminal device. The terminal equipment further analyzes the equipment information to obtain a temporary identification code and a temporary authentication code generated by the screen projection equipment, and when a user scans the equipment identification of the screen projection equipment through the terminal equipment, the terminal equipment adopts the temporary identification code to compare with the obtained equipment identification to judge whether the equipment identification and the temporary identification code are consistent; if the two are consistent, the screen projection device corresponding to the device identifier scanned by the terminal device is the screen projection device to be projected, and the terminal device and the screen projection device establish first-step connection. It should be noted that after the first connection between the terminal device and the screen projection device is established, the screen projection device cannot project the screen, and a second connection between the terminal device and the screen projection device needs to be further established.
Step S230: receiving authentication information sent by terminal equipment;
in this embodiment, if the terminal device determines that the temporary identification code is consistent with the device identifier, the terminal device sends the temporary authentication code as authentication information to the screen projection device. And the screen projection equipment receives the authentication information sent by the terminal equipment, verifies the authentication information by adopting a temporary authentication code, and determines whether to establish second-step connection with the terminal equipment according to a verification result, wherein the second-step connection is the screen projection connection established by the screen projection equipment and the terminal equipment.
Step S240: and if the authentication information passes the verification, screen projection connection is established with the terminal equipment.
In this embodiment, if the screen projection device determines that the authentication information is consistent with the temporary authentication code, it confirms that the authentication information sent by the terminal device passes verification, and then establishes screen projection connection with the terminal device. The specific way of determining that the authentication information is consistent with the temporary authentication code may be: if the authentication information and the temporary authentication code are identified to be both composed of numbers, the absolute values of the two are subtracted or divided, and if the operation result of the two is 0 or 1, the two are determined to be consistent. Or if the authentication information and the temporary authentication code are combined by other symbols such as letters and numbers, converting each symbol of the authentication information and the temporary authentication code into a number through an ASCII code comparison table, and verifying whether the authentication information is consistent with the temporary authentication code by adopting the method.
Step S250: and sending a screen projection connection completion instruction to the terminal equipment.
In this embodiment, after the screen projection device establishes screen projection connection with the terminal device, a screen projection connection completion instruction is sent to the terminal device, the terminal device responds to the screen projection connection completion instruction, screen projection information is sent to the screen projection device, and the screen projection device displays the screen projection information.

As shown in fig. 4, in the third embodiment of the present application, when executed by a terminal device, the method for connecting a screen projection device of the present application includes the following steps:
step S310: and sending an information acquisition request to the screen projection equipment.
In this embodiment, the information obtaining request is a request for obtaining device information generated by the screen projection device by the terminal device. Before the user performs screen projection connection with the screen projection device through the terminal device, the user needs to execute operation of approaching the terminal device to the screen projection device. When a user presses the terminal equipment close to the screen projection equipment, the terminal equipment sends an information acquisition request to the screen projection equipment, so that the screen projection equipment responds to the information acquisition request and then sends the generated equipment information to the terminal equipment through the NFC data exchange module.
Step S320: and receiving the equipment information sent by the screen projection equipment, and generating authentication information according to the equipment information.
In this embodiment, after the screen projection device responds to the information acquisition request, the NFC data exchange module sends the generated device information to the terminal device, and the terminal device receives the device information of the screen projection device through its own NFC data reading module and generates authentication information according to the device information. And generating an authentication letter according to the equipment information, specifically analyzing the received equipment information to obtain the temporary identification code and the temporary authentication code, and determining the temporary authentication code as the authentication information. The authentication information is information verified by the screen projection device before the screen projection device establishes screen projection connection with the terminal device.
Step S330: and scanning the equipment identification of the screen projection equipment.
In this embodiment, after the terminal device obtains the device information of the screen projection device, a user needs to perform an operation of scanning a device identifier of the screen projection device through the device terminal, when the device terminal scans the device identifier of the screen projection device, the obtained temporary identifier code is compared with the device identifier line, whether the obtained temporary identifier code is consistent with the device identifier line is judged, and whether a first-step connection is established with the screen projection device is determined according to a result of whether the obtained temporary identifier code is consistent with the device identifier line.
Step S340: and if the comparison relation between the equipment identification and the equipment information is judged to meet the information authentication condition, sending the authentication information to the screen projection equipment.
In this embodiment, the comparison relationship between the device identifier and the device information refers to a similar relationship between the device identifier and the device information, and the information authentication condition is that the device identifier is consistent with the temporary identifier. If the terminal equipment judges that the comparison relation between the equipment identification and the equipment information meets the information authentication condition, namely the temporary identification code is consistent with the equipment identification, namely the temporary identification code is the same as the equipment identification, the screen projection equipment corresponding to the equipment identification scanned by the terminal equipment is the screen projection equipment to be projected, and then the first-step connection is established between the terminal equipment and the screen projection equipment. After the first-step connection between the terminal equipment and the screen projection equipment is established, authentication information is sent to the screen projection equipment, so that the screen projection equipment adopts the temporary authentication code to verify the received authentication information, whether second-step connection is established with the terminal equipment or not is determined according to a verification result, and the second-step connection is the screen projection connection established between the screen projection equipment and the terminal equipment.
Step S350: and receiving a screen projection connection completion instruction sent by the screen projection equipment.
In this embodiment, if the screen projection device determines that the authentication information is consistent with the temporary authentication code, it determines that the authentication information sent by the terminal device passes verification, establishes screen projection connection with the terminal device, and sends a screen projection connection completion instruction to the terminal device. And after receiving a screen projection connection completion instruction sent by the screen projection equipment, the terminal equipment sends screen projection information to the screen projection equipment for display.
