Mobile PM2.5 (Particulate Matter2.5) detection system

Abstract

The invention discloses a mobile PM2.5 (Particulate Matter 2.5) detection system, which comprises an air collection unit, a positioning unit, a PM2.5 detection unit, a video unit, a meteorological phenomenon unit and an information processing unit. By adopting the system disclosed by the invention, on one hand, monitoring the air pollution concentration of each region of the native area is more manoeuvrable and flexible, an air pollution concentration distribution diagram of the native area is automatically drawn, and heavy pollution areas and pollution sources in the native area are conveniently determined; on the other hand, required relevant equipment can be conveniently and quickly added as needed, and main components of PM2.5 of each region of the native area are analyzed; meanwhile, by comprehensively considering the meteorological factor, the greening factor, the factor of layout planning of buildings and the like of each region of the native area, the reason of air pollution of the native area is analyzed, and a scientific and reasonable basis is provided for constituting PM2.5 treating measures of the native area.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a mobile PM2.5 detection system. Background technique [0002] Since 2013, the central and eastern regions of the country have been caught in severe smog and pollution. The Central Meteorological Observatory upgraded the blue warning of heavy fog to yellow warning. Heavy and severe pollution over a wide area. Smog is the result of the interaction between specific climate conditions and human activities, and its main component is PM2.5; the so-called PM2.5 refers to solid suspended matter floating in the air with a diameter of less than 2.5 microns. Because it can be directly inhaled into the lungs and seriously affect people's health, it has attracted widespread attention. In addition, hazy weather seriously affects the visibility of travel, which in turn affects the safety of transportation, which is not conducive to the development of social economy. [0003]...

AI Technical Summary

Problems solved by technology

The current method of air pollution monitoring is to use expensive fixed equipment monitoring or dedicated monitoring equipment, which is a coarse-grained system in pollution measurement, which can only obtain a small amount of pollution information, and the raw data obtained in a coarse-grained system , to infer the concentration and extent of air pollution through the diffusion model

Large-scale deployment of this system is limited by its expensive cost, which is not suitable for promotion

At the same time, fixed equipment cannot flexibly change monitoring according to monitoring needs
