Construction Site Dust Monitoring Station: Building a Smart Site Environmental Supervision System

Challenges of Construction Site Environmental Pollution and the Necessity of Real-Time Monitoring

Harm of Dust and Noise to Environment and Health

As urban construction expands, construction sites contribute to city development while generating increasingly prominent dust and noise pollution.

Dust Hazards: Fine particulate matter (PM2.5, PM10) severely affects air quality and visibility, impacting traffic. More critically, these particles carry toxic substances that enter the respiratory tract, causing pharyngitis, bronchitis, and even lung infections, seriously threatening public health.

Noise Hazards: Construction noise exceeding legal limits disturbs residents, affects rest and sleep, and long-term exposure can lead to reduced concentration, lower work efficiency, cardiovascular diseases, and hearing damage.

Under increasingly stringent environmental governance requirements, real-time, objective, and scientific quantification of dust and noise emissions and source control has become a core issue for environmental protection departments and construction enterprises.

Definition and Core Functions of Construction Site Dust Monitoring Station

A construction site dust monitoring station (also known as a smart dust & noise monitoring system) is a monitoring system specifically developed for environmental pollution in urban construction projects, road construction, material yards, etc. It integrates modern IoT sensing, wireless communication, video, and cloud computing technologies to collect, transmit, analyze, and apply data, achieving remote real-time online monitoring and analysis of dust concentration (PM1.0/PM2.5/PM10) and noise intensity at construction sites.

Core Functions: Real-time quantification of dust and noise data, exceedance warnings, trend analysis, and remote video evidence, providing scientific basis for joint enforcement by environmental protection, urban construction, and transportation regulatory departments and refined management by construction units.

Structure and Technical Principles of NiuBoL Dust Monitoring Automatic Weather Station

System Structure: Multi-Element Integrated Monitoring

NiuBoL’s dust monitoring automatic weather station is a comprehensive platform integrating multiple sensors, data acquisition, transmission, and display functions.

A complete smart construction dust & noise monitoring system consists of:

Data Acquisition Module (Sensor Array): The core that acquires environmental data
• Dust Sensor (NBL-W-PM): Monitors PM1.0, PM2.5, PM10 concentration
• Noise Sensor (NBL-W-NS): Monitors ambient sound level intensity
• Meteorological Sensors: Wind speed (NBL-W-SS), wind direction (NBL-W-DS), temperature/humidity/pressure (NBL-W-LBTH), etc.

Data Acquisition & Transmission Module: Integrates and processes data, transmits in real time via 4G/5G, WiFi, or wired network to the cloud platform
Display Screen (LCD): Real-time on-site data display for warning and publicity
Cloud Platform & Alarm Module (NiuBoL Environmental Monitoring Cloud Platform): Receives, stores, analyzes data, provides remote control, data analysis, exceedance warnings, etc.
Auxiliary Modules: Metal protective enclosure, mounting bracket, power supply system (mains or solar)

Core Sensor Technology Principles

1. Dust Monitoring (NBL-W-PM Outdoor Dust Sensor)
Uses laser scattering principle. When dust particles pass through the laser beam, they produce scattered light. The sensor detects scattered light intensity and converts it into particulate concentration via algorithms. High accuracy, fast response, simultaneously detects PM1.0, PM2.5, and PM10.

2. Noise Monitoring (NBL-W-NS Noise Sensor)
Digital, modular design using DSP chip and high-precision microphone to collect sound waves. Converts sound pressure to electrical signals, amplifies and digitally processes them to accurately measure ambient sound intensity. Wide frequency band, excellent stability, no manual range switching required.

3. Meteorological Auxiliary Monitoring
Wind speed/direction sensors: Critical for dust diffusion path and impact range analysis. Strong winds may trigger dust exceedance, prompting timely activation of mist cannons.
Temperature/humidity/pressure sensor: Monitors environmental parameters affecting particulate diffusion and measurement accuracy, providing scientific basis for data calibration and dust trend analysis.
