This invention discloses a smart construction
site management method and
system based on
the Internet of Things (IoT), relating to the field of smart construction site environmental control technology. The method includes performing
vector projection on the
point cloud of the
material storage area's surface to obtain the tangential
wind speed components of the surface points, calculating the
voxel center elevation difference of the three-dimensional
point cloud, screening wind
erosion active areas, uniformly dividing the wind
erosion active areas into sub-zones, calculating the horizontal drift distance, predicting the landing center coordinates, and generating a predicted landing circle; calculating the
fog cannon coverage circle, determining the spatial intersection of the predicted landing circle and the
fog cannon coverage circle, calculating the
fog cannon activation time in the
control area, and sending the activation time to the fog cannon for execution. This invention improves the
dynamic simulation capability of dust particle falling behavior by combining
particle size distribution quantification with a
settling velocity estimation model, and improves the accuracy of
dust fall range prediction by calculating the horizontal drift of
dust particles combined with a landing circle prediction model.
