In today´s era, air quality is closely related to everyone´s life and has become a highly anticipated social focus. With the rapid advancement of global industrialization and urbanization, the impact of human activities on the atmospheric environment is becoming increasingly profound, and the air quality is facing unprecedented challenges.
Micro air environment monitoring stations are widely used for 24-hour continuous online monitoring of conventional pollution factors and meteorological parameters in the air. The analyzed data is provided to environmental regulatory departments as a reference for air quality and assists in environmental decision-making. The monitoring factors include: extremely fine particulate matter (PM2.5, PM10), ozone, sulfur dioxide, carbon monoxide, hydrogen sulfide, nitrogen oxides, volatile organic pollutants, total suspended particulate matter, lead, benzene, meteorological parameters, visibility, etc. The IoT technology is used to obtain real-time data from each monitoring point. Based on GIS technology, an air quality map is presented. At the same time, through the analysis and judgment of monitoring data, air quality warning, analysis of main pollutant source types, visualization of pollution status, and tracing of pollution source diffusion process are provided. On site real-time data visualization is also available. LED Screen, high-definition LCD display, supporting the cloud platform on the WEB side, WeChat official account, and monitoring the query of control data on the large screen; High data accuracy, good stability, easy installation, simple maintenance and remote calibration, integrating big data analysis models, providing a basis for regulatory authorities to carry out pollution source analysis in urban air quality control, win the battle for blue sky protection, and implement scientific governance of atmospheric pollution prevention and control.
