Online Dust Monitoring System: Precision Monitoring & Adaptive Control for Urban Construction

In the process of urban construction and development, dust and noise pollution have increasingly become prominent issues affecting environmental quality and residents' quality of life. The Online Dust Monitoring System, with its intelligent supervision and intelligent dust suppression functions, is bringing new changes to environmental regulatory work.

The System's Technical Framework and Monitoring Capabilities

The system builds an all-around monitoring network based on core technologies such as light scattering and micro-electromechanical systems (MEMS). For concentrations of various particulates like PM2.5, PM10, and TSP, the system uses laser dust sensors to precisely calculate the quantity and mass concentration of particulates by measuring the intensity of scattered light generated when laser irradiates particulates in the air. It also conducts 24-hour uninterrupted monitoring of meteorological parameters including noise decibel values, temperature, humidity, wind speed, wind direction, and atmospheric pressure. Sensors collect analog signals, which are converted into digital signals by a data collector for preliminary analysis, and then uploaded to the cloud environmental monitoring platform in real time and stably via wireless communication technologies such as 4G and GPRS.

Core Advantage: Intelligent Supervision

The cloud platform, the core of intelligent supervision, features powerful data processing capabilities to store and deeply analyze massive monitoring data, presenting them visually in the form of intuitive charts, maps, etc. After logging in, managers can not only view detailed data of each monitoring point in real time but also analyze the laws and trends of pollution through historical data comparison. When monitoring data exceed the preset environmental protection standard thresholds, the system immediately sends alarms to relevant personnel via text messages, platform pop-ups, etc., while automatically capturing on-site pictures or videos to retain law enforcement evidence. The platform sets different permission management levels, allowing front-line inspectors to management personnel to obtain data as needed, enabling three-dimensional supervision of construction sites, factories, mines, and other venues.

Intelligent Dust Suppression: Linkage with Spraying Systems

The system links with a spraying linkage controller. Once dust concentration exceeds the standard, the controller quickly activates dust suppression equipment such as fog cannons, 围挡喷淋 (enclosure sprinklers), and automatic spraying systems. Fog cannons atomize water into tiny particles through high pressure, which combine with airborne dust to settle; enclosure sprinklers form a water curtain around construction sites to block dust diffusion; the automatic spraying system can automatically adjust the spraying range, intensity, and duration according to on-site dust conditions. Users can also remotely view equipment operating status via the cloud server and flexibly set linkage strategies to achieve unattended and efficient dust suppression management.

Application Scenarios

Currently, the system is widely used in construction sites, garbage dumps, demolition sites, factories, and other places. In construction sites, it helps construction units implement dust prevention measures; in industrial zones, it effectively controls dust and noise emissions during production, providing real-time, accurate, and comprehensive law enforcement evidence.
