Water bloom early warning system and method based on combination of online monitoring and image recognition

Abstract

The invention provides a water bloom early warning system and method based on combination of on-line monitoring and image recognition. The system comprises an on-line acquisition device and a background early warning platform. The online acquisition device is suspended in a to-be-detected water body and comprises a physicochemical index detection template and an image acquisition module, the physicochemical index detection module is used for acquiring water quality physicochemical indexes of the to-be-detected water body, and the image acquisition module is used for acquiring images in the to-be-detected water body; and the background early warning platform compares each water quality physicochemical index with a corresponding set threshold, determines the eutrophication degree of the to-be-detected water body, evaluates the water bloom outbreak risk level in combination with the color similarity between the image in the water and a reference old water image, and performs water bloom early warning according to the outbreak risk level. Through automatic on-line monitoring of water quality physicochemical indexes and combination with an image recognition technology, while accurate water bloom prediction is achieved, the labor and time cost is reduced, and the method can be widely applied to water source monitoring places such as rivers, lakes and reservoirs and has high actual use value.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a water bloom early warning system and method based on the combination of online monitoring and image recognition. Background technique [0002] "Water bloom", also known as water eutrophication, is a phenomenon in which some algae bloom explosively due to pollution of the water body, resulting in changes in the color of the water body and the formation of thin or thick algae floating objects on the water surface. The algae that cause water bloom are mostly cyanobacteria, also have green algae, euglena and diatom etc. It is not only the obvious manifestation of water pollution, but also the further deterioration of water pollution, resulting in the lack of oxygen in the water body, leading to suffocation and death of aquatic animals; at the same time, some algae produce algae toxins, which cause poisoning of aquatic animals and even humans and livestock, and fina...

Problems solved by technology

Due to the short period of water bloom generation, it usually only takes a few days from the beginning of growth to the full outbreak. Therefore, in order to ensure the early warning effect, it is necessary to send special staff to carry out frequent on-site monitoring. The time cost is high, and the stability of early warning cannot be guaranteed
