Background
Currently, water environment monitoring presents an informationized and diversified situation, water quality detection methods are numerous, and the water environment monitoring is mainly classified into two monitoring methods, namely a contact monitoring method and a non-contact monitoring method.
The contact monitoring method comprises the following steps: (1) the method comprises the steps of manual sampling, laboratory test method, manual sampling and laboratory detection, is a direct water sampling method, and belongs to a contact detection mode. The method has high detection precision, but wastes time and labor, can only detect various index conditions of water quality, can not effectively find a pollution source through a detection means under the condition of unknown pollution sources, and is difficult to deal with some sudden sewage discharge events and oil leakage water pollution events in large-area water areas. In addition, the existing water quality sampling method is mainly manual on-site sampling, but most of inland rivers in the country are limited by urban development at present, so that the conditions of manual monitoring and sampling cannot be fully met, the number of water body monitoring points is insufficient, the coverage rate is insufficient, the monitoring data cannot objectively reflect the water quality pollution condition of a monitoring area, and the timely supervision and advanced prevention and control work cannot be realized; (2) the method is visual and rapid in field detection by the handheld detector, but the type of detected water quality is limited, the method is also limited by a detection field, the detection precision is low, and the method can be only used for checking the water quality on the field and in emergency or only used for primarily judging the water quality.
The non-contact monitoring method comprises the following steps: the hyperspectral remote sensing water quality monitoring is a pattern in which monochromatic light is dispersed and arranged in sequence according to the size of wavelength (or frequency) after the polychromatic light is dispersed by a dispersion system (such as a prism and a grating). Different elements, atoms, molecules, substances have their own spectral fingerprints, and light interacts with substances (absorption, fluorescence, raman, etc.) to produce different colors and different spectra. The hyperspectral remote sensing technology utilizes an ultraviolet-visible light near-infrared light source in the range of 200nm to 2500nm to irradiate a water body to be detected, a detector receives optical signals reflected by an object, the optical signals are decomposed into hundreds of wave bands by utilizing a light splitting technology, the molecular composition and the material content of the object are reflected by collecting the energy value of each wave band, and the technology integrates the technologies of spectrum monitoring, liquid level monitoring, video monitoring and the like, so that the real-time high-frequency monitoring of various water quality parameters under the condition of complex weather can be realized. However, the non-contact monitoring method is monitoring through an indirect method, can only be calculated through a relevant AI algorithm, cannot sense the actual water ecological environment condition, is greatly influenced by objective environmental factors such as weather and the like, and monitoring data may be distorted.
