The invention is suitable for the technical field of flying dust monitoring, and provides a
road construction site all-weather flying dust online monitoring method and
system, and the method comprises the following steps: collecting flying dust data and
wind power information through a sensor; the particulate matter concentration is judged, and the particulate matter concentration exceeding the standard and the corresponding coordinate position,
wind speed data and
wind direction data are screened out; determining a flying dust
source area according to the coordinate position, the
wind speed data and the
wind direction data; a road transportation monitoring video is called, and the area where the transportation vehicle is located is determined according to the
time information and the road transportation monitoring video; a
road construction map is called, and the area where the transport vehicle is located is marked in the
road construction map; and comparing and analyzing the flying dust
source area with a road construction map, determining a potential flying dust source position, and sending the potential flying dust source position to an inspection terminal. According to the invention, the flying
dust pollution source can be accurately tracked, and the inspection personnel can quickly position the potential flying
dust pollution source according to the information.
