[0002] As a common marine ecological problem, red tide not only poses a threat to marine biodiversity, but may also have an adverse impact on human health and economic activities. The traditional red tide monitoring method is to use a buoy system based on machine learning to analyze seawater samples to identify early signs of red tide; use remote sensing technology to invert water quality parameters to achieve red tide monitoring and early warning; construct a red tide short-term prediction model through artificial neural networks (such as BP network and RBF network), and use high-frequency sampling data from buoys to improve prediction accuracy; deploy ecological buoys as monitoring platforms, continuously collect hydrological, meteorological and water quality data, and combine statistical methods and manual observations to comprehensively monitor the entire process of red tide.

[0003] Disadvantages of existing red tide monitoring methods: Accuracy and response speed: Although traditional remote sensing monitoring of red tides can cover a wide area, it cannot fully and accurately reflect all indicators of red tide occurrence, resulting in inaccurate or incomplete warning information. Therefore, it lacks accuracy in the identification of specific algae species and the assessment of red tide intensity. At the same time, it often relies on periodic sample collection and laboratory analysis, which has obvious time delays and makes it difficult to achieve immediate warning of red tides; cost issues: current red tide monitoring technology relies on expensive remote sensing equipment and complex analytical instruments. The high cost limits the popularization and large-scale application of these technologies; monitoring range limitations: existing equipment is often bulky and limited to monitoring of fixed sea areas. It is not convenient for rapid transfer and adjustment, and its portability and ease of operation are limited, which affects the flexibility of monitoring and the ability to respond to the suddenness of red tides; operational difficulty: these technologies are complex to operate and require professional personnel to operate, which limits their use by the general public.
