Based on the foregoing wireless network card, an embodiment of the present application provides a flowchart of a connection method for a wireless access point, where the flow of the method may be executed by the wireless network card, and the method includes the following steps:

s401, when the wireless network card is inserted into the terminal device through the USB interface of the wireless network card, the wireless network card detects whether the storage medium stores the encrypted file.

S402, when the encrypted file is determined to be stored, setting the USB interface of the wireless network card to be in an equipment mode, transmitting the encrypted file to the WiFi chip through the USB interface, and decrypting the encrypted file by the wireless network card through the WiFi chip to obtain network connection information.

And S403, the wireless network card is connected with the wireless access point through the WiFi chip according to the network connection information.

In the step S402, the wireless network card may decrypt the encrypted file in a hardware manner or a software manner. Illustratively, the network connection information may be an SSID and password of the wireless access point. When the wireless network card acquires the SSID and the password, the wireless local area network can be accessed quickly.

For example, as the network configuration of the drone group is taken as an example, before the drone has no user interface, it is usually necessary to manually configure the network separately for each drone of the drone group. In the invention, a user only needs to plug the wireless network card of the multifunctional U disk into the unmanned aerial vehicle, because the encryption file is introduced into the wireless network card of the multifunctional U disk, the USB interface of the wireless network card is set to be in an equipment mode, the wireless network card of the unmanned aerial vehicle can decrypt the encryption file after detecting that the storage medium comprises the encryption file, network connection information obtained by decryption from the encryption file is obtained, the operation of distribution network is completed, and finally the wireless network card is accessed into a wireless router or other wireless access points. Therefore, the rapid distribution network of the unmanned aerial vehicle group can be realized, and the time for the distribution network is saved.

In addition, in other possible cases, if the wireless network card detects that the encrypted file is not stored in the multifunctional USB, the method further includes S404, when it is determined that the encrypted file is not stored, setting the USB interface of the wireless network card to be in the storage mode, and setting the WiFi chip of the wireless network card to be in the listening mode. The wireless network card may then access the network in any of the following ways.

In a first possible implementation manner, the wireless network card may receive N frames of broadcast messages, where N is a positive integer; and determining network connection information according to the N frames of broadcast messages. That is to say, the wireless router can send broadcast data to the surroundings, so that the wireless network card can sense the broadcast message, and the network connection information is determined according to the broadcast message, thereby completing the rapid network distribution. In a possible implementation manner, the wireless network card may parse one character from a group of lengths according to the length of the received broadcast message, and a plurality of characters form the network connection information. For example, 10 broadcast frames constitute 1 group of broadcast frames, so that 10 broadcast frames can be parsed out one character, thereby recovering the network connection information. In another possible implementation, the broadcast packet may carry an encrypted file, and the wireless network card may decrypt the encrypted file to obtain the encrypted file. The former embodiment is more versatile than it is. For example, the wireless network card on each unmanned aerial vehicle in the unmanned aerial vehicle group can receive broadcast data from the ground router, and the wireless network card on the unmanned aerial vehicle can complete decryption of encrypted files in the broadcast data by using a preset secret key, so that network connection information is obtained, and the wireless router is accessed quickly.

In a second possible implementation, because the USB interface of the wireless network card is in the storage mode, when the terminal device into which the wireless network card is inserted can receive the operation of the user, the user can initiate the operation, and the encrypted file is imported into the wireless network card through the terminal device, so that the wireless network card re-executes the above S401 to S403, or when the terminal device into which the wireless network card is inserted cannot receive the operation of the user, the user can reinsert the wireless network card into the PC, and the user can initiate the operation, and the encrypted file is imported into the wireless network card through the PC, so that the wireless network card re-executes the above S401 to S403.

In summary, in the above embodiment, the encryption file is pre-stored in the wireless network card, so that the function of plug and play of the wireless network card is realized, and the terminal device inserted into the wireless network card can be quickly accessed to the wireless network.

Based on the foregoing wireless network card, a second embodiment of the present application provides a flowchart of a connection method for a wireless access point, where the flow of the method may be executed by the wireless network card, and the method includes the following steps:

s501, the wireless access point acquires the network connection information of the wireless access point.

And S502, the wireless access point generates an encrypted file according to the network connection information.

S503, the wireless access point sends a broadcast message, and the broadcast message comprises the encrypted file.

S504, when the wireless network card is inserted into the terminal device through the USB interface of the wireless network card, the WiFi chip of the wireless network card is set to be in a monitoring mode, and the wireless network card receives the broadcast message.

S506, the wireless network card decrypts the encrypted file through the WiFi chip to obtain the network connection information.

And S507, the wireless network card is connected with the wireless access point through the WiFi chip according to the network connection information.

That is to say, on the one hand, under the condition that the wireless network card is not configured with the encrypted file in advance, the wireless access point can send the broadcast message to the outside, so that the wireless network card on the terminal device can receive the message, and then decrypt the encrypted file to obtain the network connection information. On the other hand, when the wireless network card is applied to the networking condition of the terminal equipment group, the operation flow that the user introduces the encrypted files into the wireless network card one by one in advance can be saved, the operation steps are simplified, and the user experience is improved.

For example, as the network configuration of the drone group is taken as an example, before the drone has no user interface, it is usually necessary to manually configure the network separately for each drone of the drone group. In the invention, a user only needs to plug a multifunctional wireless network card into the unmanned aerial vehicle, because the encryption file is led into the multifunctional wireless network card, the USB interface of the wireless network card is set to be in an equipment mode, the Wifi chip of the wireless network card is set to be in a monitoring mode, the wireless network card can decrypt the encryption file after receiving the broadcast message, network connection information obtained by decryption from the encryption file is obtained, distribution network operation is completed, and the wireless network card is finally accessed into a wireless router or other wireless access points. Therefore, the rapid distribution network of the unmanned aerial vehicle group can be realized, and the time for the distribution network is saved.

In summary, in the second implementation, under the condition that the encrypted file is not stored in the wireless network card in advance, the encrypted file can also be obtained by using the broadcast message, and the terminal device inserted into the wireless network card can be quickly accessed to the wireless network by using the plug-and-play function of the wireless network card.

Based on the foregoing wireless network card, a third embodiment of the present application provides a flowchart of a configuration method for a wireless network card, where the flow of the method may be executed by an upper computer, as shown in fig. 6, the method includes the following steps:

s601, the upper computer detects whether the wireless network card is inserted.

S602, when the wireless network card is detected, the upper computer acquires the working mode of the wireless network card.

And S603, when the working mode is the storage mode, the upper computer receives the operation of the user.

S604, responding to the operation, the upper computer transmits an encrypted file to the wireless network card, wherein the encrypted file comprises the network connection information of the wireless access point.

In a possible implementation manner, before detecting whether the wireless network card is inserted, the upper computer may first acquire network connection information of the wireless access point from the wireless access point; and then generating an encrypted file according to the network connection information.

Illustratively, when a user inserts the USB interface port of the wireless network card into the upper computer, the user can simultaneously dial the sliding button 5 to set the wireless network card in the storage mode, so that when the user acts on the upper computer, the user can import the encrypted file into the upper computer, and the wireless network card is configured with the network connection information of the wireless access point.
