System and method for checking river drainage points based on changes in sewage fingerprints

Abstract

The invention discloses a system and method for checking river drainage points based on changes in sewage fingerprints. The system includes at least one acquisition device and at least one monitoringdevice arranged behind a known drainage point; the acquisition device obtains a fluorescence map of a river node where the acquisition device is located and sends the fluorescence map to the monitoring device; the monitoring device obtains all characteristic vertices of the fluorescence map and constructs the feature geometry based on all the feature vertices; the monitoring device compares the feature geometry with the drainage geometry of a drainage point; after difference between the feature geometry and the drainage geometry is equal to or greater than a difference threshold, whether rivernodes or drainage points between the river node where the acquisition device is located and the drainage point have abnormality is determined by the monitoring device. The system is advantaged in that the system can obtain the fluorescence map of the known drainage point at a back river node, whether the river nodes or the drainage points between the river node where the acquisition device is located and the drainage point have abnormality is determined by the monitoring device according to the fluorescence map and a drainage map of the known drainage point.

Description

technical field [0001] The invention relates to the field of sewage treatment and prevention; in particular, it relates to a system and method for checking river sewage discharge points based on changes in sewage fingerprints. Background technique [0002] The issue of river sewage discharge is a hot issue at present; many illegal units or individuals discharge sewage into the river. However, law enforcement agencies cannot completely cover all nodes of the river, and it is difficult to detect non-compliant sewage problems in time. Contents of the invention [0003] Embodiments of the present invention at least disclose a system and method for checking river sewage discharge points based on changes in sewage fingerprints. The system of this embodiment can obtain the fluorescence spectrum of the known pollution discharge point at the back channel node, and check whether there is an abnormal sewage discharge event between the river channel node and the sewage discharge poin...
