The Osen airborne environmental online monitoring system is currently applied to various ordinary cars and other vehicles as carriers for airborne environmental monitoring. The monitored parameter types include dust, air quality, noise, VOC, odor, meteorological and other parameters that can be freely matched. With the movement monitoring of vehicles in urban areas, it is possible to understand the pollution situation within the area and monitor the pollution within the range, achieving macro to micro monitoring within the area. At the same time, by utilizing big data and cloud platform technology, combined with environmental thermal pollution models, the collected data will be scientifically predicted according to the laws and trends of environmental quality changes, providing a scientific basis for pollution control.
