[0002] While smart home and display products are becoming increasingly diverse, and examples of combining the two are ubiquitous—such as refrigerators with embedded wireless displays in their doors and advertising boards with wirelessly controlled screens—there are few innovative smart designs for commonly used seating area signs. The ESP-WROOM-32 microcontroller, however, integrates a WiFi and Bluetooth MCU module, enabling the creation of a multi-functional seating area sign system. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a multifunctional electronic seating screen system that can communicate and connect with a desktop computer or a mobile terminal to achieve dual host computer switching connection.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The ESP-WROOM-32 microcontroller communicates with the desktop computer or mobile terminal via the WiFi module.

[0006] Among them, the mobile terminal is a mobile phone or tablet.

[0007] The lower-level power supply is a 5V DC power supply, which is connected to the Micro USB port of the ESP-WROOM-32 microcontroller.

[0015] Example

[0016] As mentioned above, the multifunctional electronic seating screen system of this application includes a basic scheme and an improved scheme. For example, an improved scheme also includes a three-button voting scheme, etc. Please refer to the above for specific application examples and feature combinations. The following will describe the preferred examples of all feature combinations.

[0017] See Figures 1-2 This embodiment presents the overall framework of a multifunctional electronic seating screen system. The ESP-WROOM-32 microcontroller serves as the control core of the hardware component. The overall hardware framework is divided into three parts: image transmission hardware design, screen display hardware design, and voting hardware design. In the image transmission hardware design, information is sent via WiFi using a mobile app, and the ESP-WROOM-32 microcontroller receives the image information via WiFi. In the screen display hardware design, the ESP-WROOM-32 microcontroller and a 3.2-inch LCD screen driven by the ILI9341 chip are used to process image information and display it on the screen. In the voting hardware design, a touch-sensitive button switch and the ESP-WROOM-32 microcontroller are used to implement voting operations, and voting data can be viewed in real time using a mobile app and a computer web browser.

[0018] The WiFi module and its connection, mobile APP, and computer web interface are all existing technologies, such as the Chinese patent application document "A WiFi-based Smart Electronic Seating Card System and Operation Method, CN106530997A", ​​etc., and will not be elaborated here. This application applies them to the ESP-WROOM-32 microcontroller, communicating with a desktop computer or mobile terminal via the WiFi module, thus expanding the host computer to include desktop computers and mobile terminals, and making adaptive improvements.

[0019] As shown in the figure, it consists of two ESP-WROOM-32 microcontrollers, two 3.2-inch TFT-LCD display modules driven by ILI9341 chips, six tactile button switches, and a 5V DC power supply module.

[0020] The 5V DC power supply powers the ESP-WROOM-32 microcontroller, enabling the microcontroller's WiFi module to function normally and allowing the APP to transmit images to the ESP-WROOM-32 microcontroller via WiFi.

[0021] The wiring design between the ESP-WROOM-32 microcontroller and the 3.2-inch display screen is the hardware foundation for enabling the APP to transmit images to the display screen via WiFi. In this process, the ESP-WROOM-32 microcontroller transcodes the received image information and finally transmits the image that conforms to the display screen's display specifications to the display screen.

[0022] Two ESP-WROOM-32 microcontrollers are each connected to three external tactile button modules, forming the hardware foundation for the voting function. In this stage, the tactile buttons are driven by a high-level voltage. The three buttons represent different voting data depending on the voting type. For single-event voting, the three buttons represent "agree," "abstain," and "disagree," respectively. For multi-event voting, the three buttons represent agreeing to event a, event b, and event c, respectively. Voting data for a voting cycle can be viewed intuitively through a mobile app and a computer webpage.

[0023] The ESP-WROOM-32 microcontroller serves as the main controller for the hardware section. Only by connecting a 5V DC power supply to the Micro USB port on the microcontroller can the entire hardware section be powered normally. The normal operating voltage of the 3.2-inch TFT-LCD display is within the range of 2.8-3.5V. Connecting the screen's VCC port to the 3.3V power supply pin of the ESP-WROOM-32 microcontroller and the screen's GND port to the microcontroller's GND pin ensures normal power-on. Connect the display's SCL clock line port to the microcontroller's D18 pin, the SDA bidirectional data line port to the microcontroller's D23 pin, the DC information port to the microcontroller's Rx2 pin, and the CS chip select port to the microcontroller's D5 pin. Due to the pin multiplexing function of the ESP-WROOM-32 microcontroller, the Serial Peripheral Interface (SPI) protocol can be used to send clock and data information for image display to the display module. The display's RES reset port is connected to the microcontroller's D4 pin; when a low-level signal is received, the screen display starts. The display's BLK backlight port is connected to the microcontroller's Tx2 pin; the screen backlight is on by default during normal power-on, and turns off when this pin receives a low-level signal.

[0024] As mentioned above, the seating screen, equipped with a desktop computer and a mobile terminal, and based on the ESP-WROOM-32 microcontroller, communicates with either the desktop computer or the mobile terminal via a WiFi module, enabling dual-host computer switching and thus achieving image and video transmission, as well as voting functions. Its applicability is broad, applicable to scenarios with only a desktop computer, such as in well-prepared meetings where relevant materials are stored on the desktop for transmission; it can also be used in scenarios with only a mobile phone or tablet, such as temporarily using the mobile phone as the host when the desktop computer fails, storing relevant materials on the phone for transmission; and it can also be used in scenarios with both a desktop computer and a mobile phone, where some relevant materials are already stored on the desktop for transmission, while additional materials such as videos or images captured by the mobile phone are transmitted directly via the phone without needing to be transferred to the desktop computer.

[0025] It should be noted that the examples of the above embodiments can preferably be combined with one or more of each other according to actual needs, and the accompanying drawings of multiple examples adopt a set of combined technical features, which will not be described in detail here.

[0026] The above description is a detailed explanation and illustration of the preferred embodiments of the present utility model. However, these descriptions are not intended to limit the scope of protection claimed by the present utility model. All equivalent changes or modifications made under the technical teachings of the present utility model shall fall within the patent protection scope covered by the present utility model.
