The invention relates to the technical field of
river pollution identification, in particular to a
pollutant identification and early warning method and
system for a river patrol
pollution source, and the method comprises the steps: constructing a three-dimensional monitoring network
system, so as to build a three-dimensional data collection architecture; establishing a space-time reference unified framework to realize synchronous time service of different monitoring nodes; deploying an
edge computing node, and implementing data preprocessing at an equipment end of the monitoring node; constructing a
pollutant feature
library which comprises spectral features,
water quality parameter correlation features and visual morphological features of river pollutants, and establishing a
water quality parameter correlation model of organic pollutants and
inorganic pollutants, which comprises a plurality of feature dimensions; and a self-adaptive threshold early warning mechanism is established, a space-time composite
early warning model is constructed, and accurate positioning and
hazard degree grading early warning of
pollution events are realized. According to the invention, through the hierarchical fusion model of
technology fusion, the precision and speed of identifying the river pollutants are improved.
