The present application relates to the field of
data processing, and particularly relates to a sewer network
pollutant tracing method, device and
system. The present application fuses multi-source
pollution data to construct an
uncertainty quantification framework, which is used to determine adaptive
pollution source tracing positioning. The experience probability of the relevant historical
pollution path is obtained by mining the historical pollution events, and the suspected pollution source point and the suspected pollution path are obtained. Then, the asynchronous strength and the blind area
gain of each suspected pollution path are accurately quantified. In the final adaptive tracing positioning process, the experience probability, the asynchronous strength and the blind area
gain of the suspected pollution path are fused to obtain an adaptive search
radius, and the tracing positioning is performed within the adaptive search
radius. The final adaptive search
radius obtained by the present application can differentiate the scheduling of search resources, reduce the waste of tracing resources and reduce the tracing cost.
