Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality monitoring technology, specifically to a drone-based device for tracing and identifying pollution sources along riverbanks. Background Technology
[0002] Riverbank pollution source tracing is a process of systematically investigating and monitoring to determine the sources of pollutants. It mainly includes the following steps: First, collecting water and sediment samples along the riverbank; second, combining hydrological data with pollution characteristic factors, and using fingerprint mapping to identify the pollution source type; simultaneously, using GIS technology to map pollution diffusion paths, and cross-validating this data with enterprise discharge permits, agricultural non-point source ledgers, etc.; finally, through pollution load calculation and time series analysis, clarifying the contribution rate of industrial point sources, domestic sewage, or agricultural runoff. When using GIS technology to map pollution diffusion paths, drones equipped with high-resolution cameras can be used for aerial photography to obtain high-precision geographic information data. However, typical high-resolution camera recognition devices and their mounting structures are limited by structural constraints. When performing visual recognition on the ground, the angle adjustment motor runs for extended periods. Furthermore, the unbalanced weight distribution of high-resolution camera recognition devices leads to high-temperature operation of the angle adjustment motor, affecting its lifespan. Additionally, monocular high-resolution camera recognition devices have a relatively small ground recognition range. Utility Model Content
