Meteorological parameters: temperature, humidity, wind speed, wind direction, air pressure
Auxiliary parameters: noise, video image (optional), rainfall (optional)
Application Scenario:
Construction sites, demolition sites, and material storage yards
Industrial parks, mines, ports and docks
Urban roads, transportation arteries, and open burning areas
2、 System architecture design
1. Hardware layer
Monitoring terminal:
Integrated high-precision sensors (such as laser scattering PM sensors, ultrasonic anemometers)
Protection level above IP65, suitable for harsh outdoor environments
Support dual modes of solar power supply or mains power supply
Data transmission module:
Wireless communication methods such as 4G/5G, LoRa, NB IoT, etc
Local storage (SD card/hard drive) to prevent data loss
Auxiliary equipment:
Camera (real-time monitoring of dust sources)
Dust reduction equipment linkage interface (such as sprinkler system, fog cannon machine)
2. Software layer
Data collection and processing platform:
Real time reception of sensor data for calibration and filtering processing
Support parallel access and data synchronization for multiple devices
Data Analysis and Visualization System:
Generate real-time concentration curves and historical data reports
Draw a thermal map of dust pollution and locate high pollution areas
Provide API interfaces to connect with government environmental protection platforms or enterprise ERP systems
Warning and Decision Support Module:
Set threshold (e.g. PM10>150 μ g/m ³ triggers warning)
Through SMS APP、 Email push alert information
Predicting pollution diffusion trends based on meteorological data
3、 Key technology implementation
Sensor calibration technology:
Regularly compare with standard monitoring equipment to ensure data accuracy
Adopting temperature compensation and humidity compensation algorithms to reduce environmental interference
Edge computing capability:
Built in algorithms in monitoring terminals to achieve local data preprocessing
Reduce transmission bandwidth requirements and improve response speed
Big data analysis model:
Constructing a pollution source identification model based on machine learning
Combining GIS technology to analyze pollution transmission pathways
4、 Deployment and operation plan
Site selection principle:
Strong representativeness: covering major dust sources and sensitive areas (such as schools and hospitals)
Avoid interference: stay away from tall buildings, trees, and other obstructions
Installation specifications:
Sensor height: 3-5 meters above the ground (to avoid human interference)
Lightning protection grounding: in accordance with GB50057 "Code for Design of Lightning Protection of Buildings"
Operation and maintenance management:
Regular inspection (once a month): clean sensors, check power supply system
Remote diagnosis: Monitor the operating status of equipment through the platform
Spare parts warehouse: stock commonly used sensors and communication modules
5、 Application Cases and Effects
Construction site management:
The Housing and Urban Rural Development Bureau of a certain city requires all construction sites to install dust monitoring devices, and the data should be uploaded to the supervision platform in real time
After implementation, the average concentration of PM10 at the construction site decreased by 30%, and the number of complaints decreased by 50%
Industrial park governance:
A certain chemical industrial park identified high emission enterprises through monitoring data, and after targeted rectification, the compliance rate of regional PM2.5 concentration has been increased to 95%
Urban road monitoring:
Based on traffic flow data, optimize the operation route of sprinkler trucks and reduce road dust by 40%
6、 Future Development Trends
Multi pollutant collaborative monitoring: integrated VOCs, NOx and other gas sensors
AI deep application: automatically identify dust sources (such as uncovered mounds) through video analysis
Blockchain technology: ensuring that monitoring data is tamper proof and enhancing credibility
5G+edge computing: realize ultra-low delay early warning and real-time dust control
Summary: The solution for online monitoring of environmental dust requires a combination of hardware reliability, software intelligence, and efficient operation and maintenance. Through closed-loop management of "monitoring warning governance evaluation", it provides scientific decision-making basis for governments and enterprises, and helps win the battle to protect the blue sky.
