Fig. 3 is a flowchart of an interaction method according to an embodiment of the present invention, where the interaction method is used in an interaction system according to a previous embodiment, and as shown in the figure, the interaction method includes:
step S301: the NFC interactive panel broadcasts a screen transmission information data packet through the Bluetooth module, the screen transmission information data packet records wireless network connection information and screen transmission connection information of a local area network where the NFC interactive panel is located, and the screen transmission information data packet carries matching information corresponding to the equipment identification.
The content of the Bluetooth module broadcast is determined by the processor of the NFC interactive tablet 10 and is given to the Bluetooth module, in the specific broadcasting process, the Bluetooth module broadcasts in a BLE (Bluetooth Low Energy) manner, other terminal devices can receive the screen transmission information data packet in a broadcast receiving manner, and in the broadcasting manner, the NFC interactive tablet 10 does not need to establish point-to-point connection based on Bluetooth pairing with other terminal devices, thereby effectively improving the information transmission efficiency.
Step S302: and when the NFC equipment detects the NFC module in the NFC interaction panel, acquiring the equipment identification of the NFC interaction panel written in the NFC module.
The user can paste the sign in the position that the NFC module is located on the mutual dull and stereotyped 10 of NFC, and the suggestion user can pass the screen connection through NFC touch-control completion. When a user has a screen transmission requirement, near field communication connection between the NFC device 20 and the NFC interaction tablet 10 can be realized by approaching the NFC device 20, especially the position where the NFC module in the NFC device 20 is located, to the position where the NFC module in the NFC interaction tablet 10 is located, and the device identifier of the NFC interaction tablet 10, which is written in advance, is acquired from the NFC module of the NFC interaction tablet 10 based on the near field communication connection, so as to acquire a screen transmission information data packet from the received bluetooth broadcast based on the device identifier.
Step S303: and the NFC equipment analyzes the screen transmission information data packet carrying the matching information corresponding to the equipment identification according to the equipment identification.
One setting mode of the matching information is to directly use the device identifier as the matching information, and the NFC device 20 directly confirms whether the device identifier exists in the screen transmission information data packet by using the obtained device identifier, and confirms that the corresponding screen transmission information data packet is the matched screen transmission information data packet if the screen transmission information data packet exists in the screen transmission information data packet. Another setting mode of the matching information is that the matching information is used for encrypting a screen transmission information data packet, the device identifier is used for decrypting the screen transmission information data packet, the NFC device 20 attempts to decrypt the received screen transmission information data packet by using the obtained device identifier, and when the decryption is successful, the matching is successful, so that the screen transmission information data packet to be analyzed is confirmed. In the screen transmission information data packet, various information is encoded in a preset manner, and the NFC device 20 correspondingly decodes in a preset decoding manner, so that the relevant connection information can be obtained.
In the specific connection process, because the distance of the near field communication is very short, which is obviously smaller than the communication distance of the bluetooth signal, for the same NFC interactive tablet 10, if the near field communication connection can be established with the NFC module, the screen transmission information data packet broadcasted by the bluetooth module can be received. Therefore, if the near field communication connection is established currently and only one screen transmission information data packet broadcasted by the bluetooth module can be received, the screen transmission information data packet can be directly confirmed to be the screen transmission information data packet matched with the equipment identifier acquired through the near field communication connection, and corresponding analysis can be performed according to the matching mode of the equipment identifier; if the near field communication connection is established at present and screen transmission information data packets broadcasted by the plurality of Bluetooth modules can be received, the screen transmission information data packets are required to be matched one by one according to the equipment identifiers, at least the screen transmission information data packets to be analyzed are successfully matched and confirmed, decoding is correspondingly carried out in a preset decoding mode, and relevant connection information is obtained.
Step S304: and establishing screen transmission connection with the corresponding NFC interactive flat plate according to the wireless network connection information and the screen transmission connection information obtained by analyzing the screen transmission information data packet.
The wireless network connection information mainly comprises a hotspot name and a password for connecting hotspots, and is used for connecting the NFC equipment to a local area network where an NFC interaction panel is located currently according to the wireless network connection information, the screen transmission connection information mainly records a screen transmission port of the NFC interaction panel, and can be realized in a mode of specifically using a string of numbers as screen transmission codes.
On the basis of the above embodiment, the present solution further includes:
step S305: and when the NFC interaction panel receives the wireless network connection information and/or the update instruction of the screen transmission connection information, the screen transmission information data packet is updated correspondingly.
In an actual using process, the wireless network connection information of the local area network where the NFC interactive tablet is located may change at any time along with user operations, for example, resetting a router, resetting a name and a password of a wireless hotspot, resetting an account password of the wireless hotspot provided by the WiFi module, and the like, and similarly, the screen transmission connection information may also change. Therefore, when the wireless network connection information of the local area network where the NFC interactive tablet is located changes or the screen transmission connection information of the NFC interactive tablet itself changes, the screen transmission information data packet is updated correspondingly, that is, although the wireless network connection information and the screen transmission connection information still exist in the screen transmission information data packet broadcasted by the bluetooth module, the specific information has been changed adaptively, so that the NFC device can perform corresponding screen transmission connection after analyzing the screen transmission information data packet.
The NFC interactive tablet broadcasts a screen transmission information data packet through the bluetooth module, the screen transmission information data packet records wireless network connection information and screen transmission connection information of a local area network where the NFC interactive tablet is located, and the screen transmission information data packet carries matching information corresponding to the device identifier; when the NFC equipment detects the NFC module in the NFC interaction panel, acquiring the equipment identification of the NFC interaction panel written in the NFC module; the NFC equipment analyzes a screen transmission information data packet carrying matching information corresponding to the equipment identification according to the equipment identification; and establishing screen transmission connection with the corresponding NFC interactive flat plate according to the wireless network connection information and the screen transmission connection information obtained by analyzing the screen transmission information data packet. In the screen transmission process, a user does not need to manually input wireless network connection information and screen transmission connection information, and does not need to call out screen transmission related two-dimensional codes on the interactive panel and then operate the mobile phone to realize screen transmission connection in a code scanning mode, and the whole screen transmission connection process can be realized by one touch of the mobile phone, so that the connection efficiency is effectively improved, and the user operation process is reduced.
