The material of the hanging picture frame front shell 1 includes but is not limited to wood, copper or various other high-strength plastics. The scene display port 16 is located at the center of the front of the hanging picture frame front shell 1. The charging and data transmission port 13 takes into account the functions of charging, data transmission and firmware update ports. The scene card 19 with a translucent effect can be customized with different theme patterns according to user needs, and is made of acrylic UV printing, 2-variable grating card or 3-variable grating card.

[0042] A groove is provided inside the scene display opening 16, and a convex lens 4 is embedded in the groove, located inside the back of the front shell 1 of the hanging picture frame and around the scene display opening 16, and a weather type icon and a key reminder icon ring 18 are provided, which are shallowly carved on the front shell 1 of the hanging picture frame. The convex lens 4 can magnify the details of the scene card 19.

[0043] A magnet fixing part 5 is provided just below the front shell 1 of the hanging picture frame. The magnet fixing part 5 is provided with interconnected high-performance strong magnetic blocks and magnetic sensors for adsorbing iron items such as key chains, providing a storage function for the entrance space of residential and commercial spaces.

[0044] A PCB customized LED weather light panel 3 is embedded in one side of the fixing member 2, and the PCB customized LED weather light panel 3 matches the weather type icon and the key reminder icon ring 18. The convex lens 4 and the magnet fixing member 5 are both limitedly fixed to the back inner part of the front shell 1 of the hanging picture frame by one side of the fixing member 2. The weather type icons include icons such as sunny, rainy, cloudy, partially cloudy, snowy, showers and lightning.

[0045] The other side of the fixing part 2 is fixedly connected to one side of the scene card limit part 6. The shape and installation position of the scene card limit part 6 match the scene card 19. A limit or photoelectric switch 7 is provided at the bottom of the scene card limit part 6. The other side of the scene card limit part 6 is connected to one side of the light diffusion plate 8. The other side of the light diffusion plate 8 is connected to the PCB customized LED backlight panel 11. The PCB customized LED backlight panel 11, the scene card 19 and the convex lens cooperate to generate a variety of color scenes.

[0046] A lithium battery 10 and a customized ESP32 control board 9 are installed on one side of the hanging picture frame rear shell 12 with heat dissipation holes facing the inside of the hanging picture frame front shell 1. The lithium battery 10 supplies power to the customized ESP32 control board 9, which is convenient for the installation and maintenance of electronic accessories. The hanging picture frame rear shell 12 is fixed to the back of the hanging picture frame front shell 1 by screws.

[0047] When the user approaches a preset distance (within 2M) from the front of the hanging picture frame front shell 1, the human body sensor 15 can transmit a sensing signal to the ESP32 control board 9. The ESP32 control board 9 transmits a light signal to the PCB customized LED backlight panel 11 according to the sensing signal, so that the PCB customized LED backlight panel 11 emits light. When the user moves away from the preset distance from the front of the hanging picture frame front shell 1, the ESP32 control board 9 starts timing. When the timing reaches the preset time, the light-off signal is transmitted to the PCB customized LED backlight panel 11, so that the PCB customized LED backlight panel 11 turns off, thereby achieving the purpose of energy saving.

[0048] When entering the key storage, the magnet fixing part 5 stores the key through magnetic force and transmits the magnetic signal to the ESP32 control board 9. The ESP32 control board 9 controls the weather type icon in the PCB customized LED weather light panel 3 and the key reminder icon ring 18 to emit light at the corresponding position of the key reminder icon ring to remind the user that the key has entered the storage state.

[0049] When the key storage is finished, the magnet fixing part 5 cuts off the transmission of the magnetic signal, and the ESP32 control board 9 controls the weather type icon in the PCB customized LED weather light panel 3 and the position corresponding to the key reminder icon ring of the key reminder icon ring 18 to not emit light, thus ending the key reminder.

[0050] The key reminder icon also has a power reminder function. When the ESP32 control board 9 obtains the power of the lithium battery 10 below 20%, the key reminder icon will flash quickly (once per second). During the charging process of the lithium battery 10 through the charging and data transmission port 13, the key reminder icon will flash slowly (once every 5 seconds). When charging is completed, the key reminder icon goes out and enters the key storage light mode, with the power reminder function as the priority.

[0051] The ESP32 control board 9 is electrically connected to the touch sensor 14. The touch sensor 14 generates a corresponding touch signal according to the user's touch mode and transmits it to the ESP32 control board 9. The ESP32 control board 9 analyzes the touch signal.

[0052] If the touch signal is a long press signal exceeding the preset time, the lithium battery 10 is controlled to power on or off; if the touch signal is a short press signal not exceeding the preset time for a single time, the real-time weather data is obtained through the network, and the PCB customized LED weather light panel 3 is controlled according to the real-time weather data, so that the weather type icon corresponding to the real-time weather data is illuminated; if the touch signal is a short press signal not exceeding the preset time for two or more times, the predicted weather data for one day after the real-time date is obtained, and the PCB customized LED weather light panel 3 is controlled according to the predicted weather data, so that the weather type icon corresponding to the predicted weather data is illuminated.

[0053] A menu definition QR code set according to a preset IP address is provided on the front of the hanging picture frame front shell 1 or the scene card 19, including: activation registration, WI-FI settings, lighting mode (a variety of lighting modes associated with weather information), power detection and user manual.

[0054] The web page corresponding to the preset IP address establishes a connection with the ESP32 control board 9 via WI-FI. The web page obtains the user's settings for "city", "time zone", "power saving mode or night light mode", "power saving mode" and "user manual", and sends a corresponding control signal to the ESP32 control board 9 to control the display of the smart hanging picture frame. At the same time, it can also obtain the power of the lithium battery 10 sent by the ESP32 control board 9.

[0055] Specifically, you can set the "city" and "time zone" when the picture frame is in use, so that the smart hanging picture frame can read real-time weather information through the Internet of Things; you can set the "lighting mode", including movie and weather themes, famous paintings and weather themes, and city and weather themes; you can set the "power saving mode or night light mode", that is, the background light will be turned off after the user leaves for 30 seconds or the brightness will be kept low for a long time; you can enter the user manual to view relevant information about the smart hanging picture frame (product name, WLAN, how to select the lighting mode, factory settings, customer service contact information, firmware version and the latest firmware update reminder).

[0056] The embodiment of the present invention further provides a method for IoT weather information linkage and variable scene, which is applied to a customized ESP32 control board in a smart hanging picture frame as described above, and the method comprises:

[0057] Obtain weather data and user lighting settings through the Internet of Things, control the weather type icon in the PCB customized LED weather light panel and the corresponding position of the weather type icon in the key reminder icon ring to emit light, and remind the user of the weather;

[0058] Obtain scene card signals from limit or photoelectric switches and user lighting settings, control the PCB customized LED backlight panel to emit light corresponding to the user lighting settings, diffuse the light to the scene card and convex lens through the light diffusion plate, so that users can see the colorful scenes corresponding to the scene card;

[0059] Obtain the magnetic force signal from the magnet fixing part, control the weather type icon in the PCB customized LED weather light panel and the key reminder icon ring in the key reminder icon ring to emit light, and remind the user that the key has entered the storage state;

[0060] Acquire a touch signal from a touch sensor, and determine whether the touch signal is a long press signal exceeding a preset time, a short press signal not exceeding a preset time, or a short press signal of two or more times not exceeding a preset time, so as to turn the machine on and off and obtain weather-related controls;

[0061] Obtain the lithium battery power and determine whether the lithium battery power is lower than a minimum threshold. If so, control the weather type icon and the PCB customized LED weather light panel at the corresponding position of the key reminder icon in the key reminder icon ring to flash quickly;

[0062] After obtaining the charging signal from the charging and data transmission port, the weather type icon and the PCB customized LED weather light panel at the corresponding position of the key reminder icon in the key reminder icon ring are controlled to flash slowly;

[0063] Get the lithium battery power and determine whether the lithium battery power is equal to the maximum threshold. If so, the PCB customized LED weather light panel at the corresponding position of the key reminder icon will go out.

[0064] The general usage process of the above-mentioned intelligent hanging picture frame based on the variable scene linked with the weather information of the Internet of Things is as follows: Figure 3-Figure 5 As shown,

[0065] Scan the QR code on the hanging picture frame shell, then open the browser, enter the web control interface of the smart picture frame, select the network name, enter the password, connect to WI-FI and activate the device. After the picture frame is activated, use the drop-down menu to set the "city" and "time zone" when the picture frame is used, and synchronize the real-time weather data with the display of the PCB customized LED weather light panel 3. Take sunny days as an example: the current local weather data is sunny, and in the weather icon area of ​​the picture frame, the "sunny" icon is lit by the PCB customized LED weather light panel 3, and other weather types, and so on.

[0066] Insert the customized scene card 19 from the scene card insertion port 17, pass through the scene card stopper 6, hit the stopper or photoelectric switch 7, and light up the PCB customized LED backlight panel 11. When the scene card 19 is pulled out from the scene card insertion port 17, the stopper or photoelectric switch 7 is released, and the PCB customized LED backlight panel 11 is turned off.

[0067] When the user attaches the key to the bottom of the smart hanging picture frame, the magnet fixing part 5 sends a signal to the ESP32 control board 9, lighting up the weather type icon and the key reminder icon in the key reminder icon ring 18, reminding the user that the key has entered the storage state. When the user removes the key from the bottom of the smart hanging picture frame, the key reminder icon goes out immediately.

[0068] The user selects the preferred background light mode, which is controlled by the PCB customized LED backlight panel 11. The background light of this smart hanging picture frame cooperates with the scene card, synchronizes the real-time weather information through the Internet of Things, and synchronizes with the weather icon lit by the PCB customized LED weather panel 3, presenting different scene atmospheres under different weather and regional culture, triggering resonance with the user's emotional changes at a certain time and place, and increasing interaction and long-term stickiness.

[0069] The user can choose the preferred lighting mode (not limited to the following three modes): Mode 1, 7 weather themes for morning and evening are extracted from famous movies, and the transitions are based on the sunrise and sunset times, with a total of 14 RGB lighting color combinations; Mode 2, 7 weather themes for morning and evening are extracted from famous paintings, and the transitions are based on the sunrise and sunset times, with a total of 14 RGB lighting color combinations; Mode 3, 7 weather themes for morning and evening are extracted from the representative colors of different cities (customizable cities, related to the user's city), and the transitions are based on the sunrise and sunset times, with a total of 14 RGB lighting color combinations; In the menu of each mode, you can check the "play mode" mode to quickly browse the lighting change effects, so as to facilitate the user to make preference settings. Taking Shanghai on January 1, 2025 as an example, the local weather data is sunny: the scene card customizes a scene in a certain place in Shanghai, and the user selects the lighting mode of mode1. At this time, the background light presents the color RBG data corresponding to a sunny day after sunrise, which appears bright orange (not limited to this); after sunset, the light gradually changes to the color RGB data corresponding to a sunny day at night, which appears blue-purple (not limited to this).

[0070] Users can also choose "usage mode", including power saving mode (backlight turns off after 30 seconds of absence) or night light mode (maintains low brightness for a long time). In the web interface, you can view product information such as current device power usage and current firmware version.

[0071] The embodiments of the present invention have the following beneficial effects: in addition to the function of storing keys in the entrance space, the background light of the picture frame device cooperates with the scene card and is synchronized with the weather icon lit by the LED weather light panel to present different scene atmospheres under different weather and regional cultures, triggering resonance with the user's emotional changes at a certain time and place, increasing interaction and long-term stickiness with the user, and becoming one of the lighting elements for lighting up important commercial spaces while increasing the fun of the picture frame decoration.
