[0080] Further, step S1 mainly includes:

[0081] S101, the terminal device opens the wireless network search function, searches and identifies the specific network signal sent by the weather station. The weather station will broadcast a default network in the initial state, so that the terminal device can easily discover;

[0082] S102, after the terminal device connects to the weather station network, open a specific web page and enter the weather station setting page. In this page, users can input local 2.4G WIFI name and password and other information;

[0083] S103, after the weather station receives the network information sent by the terminal device, it is parsed and processed by the built-in WIFI module, stored in the corresponding configuration file, and tries to connect to the specified WIFI network. Once connected successfully, the weather station will be in the same local area network with the terminal device, preparing for subsequent settings and data transmission.

[0084] Before executing step S2, after the terminal device and the weather station are successfully connected, the terminal device automatically pops up a setting web page or accesses the weather station setting web page by inputting a specific URL in the browser.

[0085] Further, step S2 includes:

[0086] Network name and password setting: users can modify the name and password of the WIFI network connected by the weather station according to their needs, in order to better manage and protect the network connection;

[0087] Location setting: users can input the specific geographic location information of the weather station, such as city, region, etc. This helps the weather station to more accurately obtain local weather data and provide more targeted information when displaying;

[0088] Display setting: users can choose different display formats to show weather data according to personal preferences and use scenarios. For example, you can set the time and date display format, temperature unit, display brightness, etc. to meet the needs of different users;

[0089] Alarm setting: users can set the alarm function on the web page to remind users at a specific time, making it convenient for users to arrange daily activities.

[0090] Further, step S3 mainly includes:

[0091] S301, after the weather station successfully accesses the network, a connection is established with a professional weather data server through a network protocol.

[0092] S302, after the obtained weather data is processed and analyzed, the weather data is displayed on the LED nixie tube according to the display format set by the user.

[0093] The LED nixie tube uses high-brightness and high-contrast LED lamp beads, which can provide clear and bright display effects under various environmental lights.

[0094] It should be particularly noted that after the user sets the weather station 1 through a terminal device such as a mobile phone and the weather station 1 is connected to a fixed network, the weather station 1 can independently connect to the network to synchronize time and weather and display the same on the LED nixie tube 13, thereby improving the efficiency and accuracy of data updating.

[0095] In summary, the weather station provided in the embodiment can provide a wide and bright visual effect for the user by using a simple LED nixie tube 13 display interface.

[0096] It should be understood that those skilled in the art can combine various embodiments in the above embodiments to obtain various technical solutions of the embodiments.

[0097] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
