基于鱼群摄食行为信号解析的无人投食船动态投喂控制方法
By deploying multiple sensors on the unmanned feeding vessel and performing signal fusion processing, the hunger status of the fish school is quantified. Combined with GPS positioning and feed bin feedback, the environmental adaptability of fish feeding behavior recognition and the systematic problems of feeding control are solved, and precise dynamic feeding is achieved.

Abstract
本发明涉及水产养殖技术领域，具体地说，涉及基于鱼群摄食行为信号解析的无人投食船动态投喂控制方法。包括如下步骤：鱼群摄食信号采集与同步传输；摄食行为信号解析与鱼群饥饿状态参数计算；动态投喂决策生成；精准投喂执行与料仓状态反馈。本发明以声传感器声学信号为基准，通过小波包时频插值对齐近红外光学信号；以与浊度倒数关联的频域子系数、与水流正关联的时域子系数、与浊度倒数正关联的空域子系数补偿环境干扰；再通过注意力加权小波包变换基于综合权重提取摄食强度梯度，量化得到连续型鱼群饥饿参数，解决了现有技术未补偿环境干扰、仅输出离散等级难以支撑精准投喂调整的问题。
