Air pollutants enter the atmosphere (input) from man-made sources or natural sources, participate in the circulation process of the atmosphere, and after a certain residence time, they are removed from the atmosphere (output) through chemical reactions, biological activities and physical deposition in the atmosphere. If the output rate is less than the input rate, it will be relatively concentrated in the atmosphere, causing the concentration of a certain substance in the atmosphere to increase. When the concentration rises to a certain level, it will directly or indirectly cause acute and chronic harm to people, organisms or materials, and the atmosphere will be polluted.
Online monitoring is an effective means to prevent and control dust pollution. It realizes dynamic display and analysis of the temporal and spatial changes of urban dust pollution, combines with environmental management and urban construction management, and realizes statistical analysis, model calculation, report analysis, planning management and other business processing, etc. Visualization, automation, and network management have the characteristics of wide applicability, fast measurement speed, high accuracy, and online real-time measurement. It is equivalent to installing a monitoring "sky eye" on the construction site. The monitoring system of the monitoring center quickly processes the returned data, and provides real-time alarms on construction sites where PM2.5 and PM10 exceed the predetermined value, which truly realizes the precise monitoring, precise management and precise supervision of the construction sites under construction.
