[0021] In actual operation, the environmental monitoring instrument 1 first collects ozone concentration data in the surrounding air through the gas sensor array 2. The signal conditioning circuit 3 amplifies and filters the raw signal output from the sensors, then transmits the processed signal to the main control chip via a flexible flat cable. The main control chip performs analog-to-digital conversion and preliminary processing on the received data before transmitting it to the graphics generation unit 5 of the display module.

The lithium battery in the power management unit is connected to the charging management circuit via wires. The USB-C interface of the charging management circuit is located on the side of the environmental monitor 1 for easy charging.

[0024] The entire workflow of the environmental monitoring instrument 1 is as follows: First, the gas sensor array 2 collects ozone concentration data and processes it through the signal conditioning circuit 3. The processed data is then transmitted to the main control chip. Second, the main control chip performs analog-to-digital conversion and preliminary processing on the received data, and then transmits the data to the graphics generation unit 5 of the display module to generate a three-dimensional spatial distribution map, which is displayed on the screen 4. Simultaneously, the main control chip transmits the data to the wireless communication unit 6 of the transmission module, which sends it to a remote terminal via an RF antenna. Finally, the hardware encryption chip of the data encryption unit 7 encrypts the transmitted data to ensure data security. Through the above steps, the environmental monitoring instrument 1 achieves real-time dynamic visualization of ozone concentration, overcoming the shortcomings of existing technologies.

[0025] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0026] In an environmental monitoring project around an industrial zone in a certain city, multiple environmental monitoring instruments with visual ozone concentration displays need to be deployed (e.g., ...). Figure 2As shown, these devices are used to monitor changes in ozone concentration in the area in real time. They are fixed to multiple monitoring points by mounting brackets 8, and the installation angle is adjusted using a leveling device 10 to ensure the devices are level, thereby improving detection accuracy. The protective cover 9 is made of transparent polycarbonate, effectively protecting the gas sensor array 2 from rain and dust, while its inner UV-resistant coating extends the device's lifespan.

[0027] Step 1: During ozone concentration data acquisition, multiple independently distributed ozone-sensitive elements in the gas sensor array 2 first respond to ozone molecules in the surrounding air. Each ozone-sensitive element is made of metal oxide semiconductor material. When ozone molecules come into contact with the sensitive element, a weak electrical signal related to the ozone concentration is generated. After receiving these raw electrical signals, the signal conditioning circuit 3 amplifies them through an operational amplifier, filters high-frequency noise interference, and a resistor network performs impedance matching to ensure the stability of signal transmission. Subsequently, the processed analog signal is transmitted to the main control chip through a flexible flat cable. The main control chip performs analog-to-digital conversion on the received signal, converting it into a digital signal for subsequent processing.

[0028] In step two, during the generation of the 3D spatial distribution map, the main control chip transmits the digitized ozone concentration data to the graphics generation unit 5 of the display module. The graphics generation unit 5 incorporates a mapping algorithm, utilizing interpolation calculations and 3D modeling technology to transform the collected ozone concentration data into an intuitive 3D spatial distribution map. For example, at a given monitoring point, areas with higher ozone concentrations are displayed in red, while areas with lower concentrations are displayed in blue. Users can clearly observe the spatial distribution characteristics of ozone concentration on the display screen 4. The graphics generation unit 5 also includes a storage chip for caching and storing the generated graphics files, allowing users to easily retrieve historical data for analysis. The display screen 4 has a refresh rate of 60Hz, enabling real-time updates of the displayed content and ensuring users can quickly grasp the changing trends of ozone concentration.

[0029] Step 3, during data transmission and encryption, the main control chip transmits ozone concentration data to the wireless communication unit 6 of the transmission module via the I2C bus. The wireless communication unit 6 includes a Wi-Fi module and a Bluetooth module. The Wi-Fi module supports the IEEE 802.11ac protocol with a maximum transmission rate of 433Mbps, while the Bluetooth module supports the Bluetooth 5.0 protocol with an effective transmission distance of 100 meters. The Wi-Fi module connects to the RF antenna via an SMA interface, and the Bluetooth module communicates with the control module via a UART interface. During the connection establishment process with the remote terminal, the wireless communication unit 6 first sends a handshake signal via the RF antenna, and then completes the encapsulation and transmission of data packets according to the communication protocol. To ensure data security, the hardware encryption chip of the data encryption unit 7 uses the AES-256 encryption algorithm to encrypt the transmitted data, preventing it from being stolen or tampered with during transmission.

[0030] Step 4: During equipment operation status monitoring and maintenance, the power management unit of the environmental monitor 1 provides stable power support through a lithium battery. The lithium battery has a rated voltage of 3.7V and a capacity of 5000mAh. The charging management circuit adopts a constant current and constant voltage charging mode, with a maximum charging current of 2A. The USB-C interface of the charging management circuit is located on the side of the environmental monitor 1 for easy charging by the user. In addition, the PCB board of the control module is equipped with a heat sink, which contacts the main control chip through a thermally conductive silicone pad to improve heat dissipation efficiency and ensure stable operation of the equipment in high-temperature environments. The protective cover 9 not only protects external components but also ensures that the content of the display screen 4 remains clearly visible under strong light due to its high light transmittance.

[0031] Step 5: When installing on complex terrain, the bottom of the mounting bracket 8 is equipped with a leveling device 10, including an adjusting screw and support feet. The adjusting screw is threaded into the mounting bracket 8, with a thread specification of M8×1.25 and an effective length of 100mm. The support feet are connected to the adjusting screw via a ball joint structure. The ball joint structure has a diameter of 20mm and a rotation angle range of ±15°, which can adapt to the installation requirements of different terrains. For example, in areas with steep slopes, the height and angle of the mounting bracket 8 can be adjusted by rotating the adjusting screw to ensure that the environmental monitoring instrument 1 always remains level, thereby improving the accuracy of the detection data.

[0032] Through the above steps, the environmental monitor 1 achieves real-time dynamic visualization of ozone concentration. The design of the gas sensor array 2 and signal conditioning circuit 3 improves the accuracy of data acquisition; the display module, through the mapping algorithm of the graphics generation unit 5, transforms the ozone concentration data into an intuitive three-dimensional spatial distribution map; the transmission module, through the design of the wireless communication unit 6 and data encryption unit 7, ensures efficient data transmission and secure protection; the design of the mounting bracket 8 and protective cover 9 enhances the adaptability and durability of the equipment. Therefore, this invention solves the shortcomings of existing ozone concentration monitoring equipment in real-time dynamic visualization, providing a more intelligent, efficient, and adaptable solution to changing environments.
