[0035] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] according to Figure 1-Figure 2 In an embodiment of the present application, a WiFi signal connection method is provided, based on a WiFi signal device, the WiFi signal device includes a main control unit 30, a function chip 20 connected to the main control unit 30, and an antenna 10 connected to the function chip 20, the method includes the following steps:

[0037] S100, creating a first network node;

[0038] S200, driving the function chip 20 to load and generate a second network node;

[0039] S300, activating the first network node and the second network node, and configuring a network file to obtain a configured first network node and a configured second network node;

[0040] S400, respectively processing the configured first network node and the configured second network node to obtain a first wireless network frequency band and a second wireless network frequency band;

[0041] S500: Scan the first wireless network frequency band and the second wireless network frequency band, and select and connect to a WiFi network according to the scanning result.

[0042] Specifically, the main function of the antenna 10 in the WiFi signal device is to receive and transmit radio waves, convert wired signals into wireless signals for transmission, or receive and convert wireless signals into wired signals. The antenna 10 converts the electrical signal from the function chip 20 into radio waves and radiates it to the surrounding environment. At the same time, it can also convert the radio waves received from the surrounding into electrical signals and transmit them back to the function chip 20 for processing. The function chip 20 is responsible for receiving and sending wireless signals, and realizing the conversion processing between data and wireless signals. The main control unit 30 is the core processing and management of the operation of the entire WiFi signal device. The main control unit 30 is mainly responsible for loading the driver of the function chip 20, calling the start.sh file, connecting two WiFis of different frequency bands and processing the data transmitted by the packaged WiFi.

The high-gain array antenna 10 used supports dual-band operation, so that 2.4GHz and 5GHz signals can be processed on the same antenna 10. At the same time, efficient transmission and reception of signals in different frequency bands are ensured. The high-gain characteristic improves the signal strength and transmission distance, and reduces the signal attenuation problem caused by long-distance transmission.

[0045] Step S200: Load the driver of the functional chip 20, and the system automatically generates a second network node (wlan1). When the driver of the functional chip 20 is loaded, the wireless network card device will be initialized and registered. The driver will use the wireless network interface management mechanism of Linux to configure the network interface to create a network node that can be used for the 2.4GHz frequency band and a network node for the 5GHz frequency band. These two network nodes correspond to the wireless transmission capabilities of two different frequency bands supported by the RTL8852BS chip. Thereby generating a second network node and a virtual first network node. It enables the simultaneous processing of network connections in two different frequency bands, thereby optimizing network performance and meeting a variety of usage scenarios.

[0046] Step S300: In one embodiment, the first network node and the second network node are activated by the ifconfig command, and network files are configured respectively, so that each node can provide a secure connection and realize automation of network configuration.

[0048] "ifconfigwlan0up

[0049] ifconfigwlan1up"

[0050] The first network node (wlan0) and the second network node (wlan1) are identified and activated by the system for subsequent network configuration, thereby improving network security and simplifying user management of network connections, allowing devices to access the Internet more conveniently.

[0051] Step S400: further process the configured network nodes so that they work in their respective wireless network frequency bands, thereby achieving true dual-band simultaneous connection, making full use of the advantages of different frequency bands, and improving data transmission rate and network stability.

[0052] S500: The system scans networks in the first wireless network frequency band and the second wireless network frequency band, evaluates the signal strength and quality of each network, and selects the best network for connection based on the information.

[0054] "iwlistwlan0scan

[0066] ifacewlan0inetdhcp

[0067] wpa-conf / etc / wpa_supplicant / wlan0.conf”

[0068] Save and close the file.

[0069] In another embodiment, the process of configuring the second network file is as follows:

By adding the second frequency band channel parameter in the wpa file of the second network node, the wireless interface of the second network node only scans the network of the corresponding frequency band. In this way, unnecessary scanning and connection attempts are avoided, scanning efficiency is improved, and the possibility of incorrect connection is reduced.

[0079] More preferably, the first frequency band channel is 2.4 GHz, and the second frequency band channel is 5 GHz.

[0080] Specifically, each first network node and second network node needs to be configured with corresponding wpa and udhcpc files so that the first network node and the second network node can connect to the correct WiFi network and obtain an IP address.

[0081] For the first network node wlan0 (assuming it is connected to a WiFi in the 2.4 GHz band), add the scan_freq=2400 parameter in the wpa configuration file of the first network node so that the first network node wlan0 specifies scanning the 2.4 GHz band. For the second network node wlan1 (assuming it is connected to a WiFi in the 5 GHz band), add the scan_freq=5000 parameter in the wpa configuration file of the second network node so that the second network node wlan1 specifies scanning the 5 GHz band.

The configuration module is responsible for configuring the network files according to the interfaces and functions provided by the driver module. These network files contain various parameters required to connect to WiFi, such as SSID, password, encryption method, etc. The configuration module writes these parameters into the network configuration file so that the subsequent processing module can use them to establish and maintain the WiFi connection. The processing module is responsible for the actual data transmission process. The processing module obtains the parameters in the network configuration file from the configuration module, and then uses these parameters to establish a connection with the target WiFi network. Once the connection is successful, the processing module can start sending and receiving data to achieve communication with other devices.

[0088] More preferably, the functional chip 20 and the antenna 10 both support dual-band channels.

[0089] Specifically, the function chip 20 supporting dual-band channels can process signals in the 2.4 GHz and 5 GHz bands at the same time, providing more flexible band selection and wider bandwidth.
