Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to an environmental monitoring device for industrial parks. Background Technology

[0002] Traditional park environmental monitoring relies heavily on fixed-point sensors (such as monitoring equipment installed on streetlight poles and building exteriors), which has problems such as complex deployment (requiring drilling and wiring), poor scalability (requiring reconstruction for new points), and data transmission delay (4G networks are prone to congestion in high-density scenarios).

[0003] However, during industrial production within the park, it is often necessary to conduct random or targeted measurements of illegal emissions from industrial units. Therefore, there is an urgent need for a portable, fixed environmental monitoring terminal for industrial parks that is compact, easy to install, supports high-speed 5G transmission, and is flexibly expandable, to solve these problems.

[0004] Based on this, this utility model proposes a park environmental monitoring device. Summary of the Invention

[0026] The portable main frame has reflective markings printed on its sides (marked "Electronic Grid Member of the Park") and LED fill lights installed at the bottom;

[0027] When the light sensor detects that the light intensity is less than 50 lux, the MCU microcontroller triggers the LED fill light control circuit to automatically turn on the LED fill light.

[0039] The solar charging panel is used to charge the lithium battery via a charging management circuit (daily average charging capacity ≥300mAh).

[0040] The sensor integration hatch (located on the front of the portable main frame, measuring 120mm × 80mm and 15mm deep) is sealed inside by a waterproof strip (EPDM rubber, compression amount 1mm, compression set ≤5%) to achieve IP54 protection (dustproof and splashproof).

[0053] Example

[0054] In a 100,000-square-meter science and technology park, 20 environmental monitoring devices (configured at one device per 5,000 square meters) will be deployed, focusing on areas such as office areas, parking lots, and green belts.

[0055] 1) Installation and debugging

[0056] Select installation locations: Based on the park's environmental monitoring needs, select 20 fixed points on the office area wall (2m high), parking lot light poles (3m high), and the green belt equipment casing (1.5m high);

[0057] Magnetic installation (taking a light pole as an example): Clean the surface of the light pole (remove rust and dust), align the magnetic interface on the back of the monitoring terminal with the light pole, and press lightly until it is firmly attached (verify the attachment force by touch or a magnetic tester ≥ 5N);

[0058] Clip installation (taking a wall U-shaped channel as an example): Pre-embed a U-shaped channel in the wall (10mm deep, spacing matches the terminal clips), align the clips on the back of the terminal with the U-shaped channel, and press down until the clips are fully embedded (verify the fixing stability through a shaking test).

[0059] Sensor calibration: After powering on, send calibration commands via mobile APP (with supporting management platform) to calibrate the PM2.5 sensor (compared with a standard particulate matter generator) and the temperature and humidity sensor (compared with a standard temperature and humidity meter) in sequence to ensure that the data error is ≤5%;

[0060] 5G network configuration: Insert a Nano-SIM card (5G data plan required), configure APN (Access Point Name) through the APP, and test data upload latency (normally ≤50ms).

[0061] 2) Daily Operation and Monitoring

[0062] Data collection and uploading: The terminal collects sensor data (PM2.5, VOC, temperature and humidity, etc.) once per minute and uploads it to the park's environmental monitoring platform via 5G network every 5 minutes;

[0063] Abnormal alarm: When a certain parameter exceeds the standard (e.g., PM2.5 > 150 μg / m³), 3 The terminal triggers a local alarm (1kHz buzzer for 5 seconds, red LED flashing), and simultaneously pushes a warning message (including location coordinates, exceeded parameters, and timestamp) to the administrator through the platform;

[0064] Power supply management: During the day, solar charging is used first (average daily charging amount ≥300mAh), and lithium battery power is automatically switched at night (battery life ≥7 days); when the battery level is <20%, the platform will push a low battery warning.

[0065] 3) Maintenance and Expansion

[0066] Routine maintenance: Clean the sensor dust filters (PM2.5, noise sensors) monthly, check the solar charging panel efficiency (clean surface dust), and test the battery capacity (replace when below 80% of rated capacity);

[0067] Functionality expansion: If you need to add water quality monitoring functionality, connect an external water quality sensor (supporting RS485 protocol) through the Type-C expansion interface, configure the sensor parameters through the APP, and realize synchronous uploading of water quality data.

[0068] Compared with existing technologies, the environmental monitoring device in this park has the following characteristics:

[0069] First, it is portable and quick to deploy: with magnetic / snap fastening dual-mode fixing interface, the installation time for a single point is less than 10 seconds (traditional fixed equipment requires more than 30 minutes), and it supports quick deployment at temporary points (such as construction areas and event sites).

[0070] Second, multi-parameter integrated monitoring provides comprehensive data: It integrates five types of sensors, including air quality, noise, and light, covering the core environmental indicators of the park and solving the problems of single function and blind spots of fixed equipment.

[0071] Third, 5G high-speed transmission, stable and reliable: using 5G modules, with a peak rate of 1Gbps, the data transmission latency in densely populated areas (such as canteens and conference rooms) is ≤50ms, which can avoid data packet loss.

[0072] Fourth, low power consumption and flexible power supply for long battery life: Built-in 1500mAh lithium battery + solar charging panel, daily power consumption ≤2Wh, can work continuously for 7 days on a full charge (≥3 days on cloudy or rainy days), no need to frequently replace batteries.

[0073] Fifth, modular expansion design with upgradable functions: The Type-C expansion interface supports the connection of other external sensors (such as water quality sensors) to meet the future expansion needs of the park; the sensor is fixed to the main body with a standardized bracket, and it only takes 5 minutes to replace the sensor.

[0074] The embodiments described above are merely one specific implementation of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution should be included within the protection scope of this utility model.
