Fish-growth-based optimal control method and system

Abstract

The invention provides a fish-growth-based optimal control method and system. The method comprises the steps that a plurality of water quality environmental data variables and fish images in an aquaculture system are collected; the fish images are subjected to analytical processing, and the fish healthy growth index is obtained; according to the healthy growth index of fish, multiple key water quality environmental data variables affecting fish growth in the water quality environmental data variables are determined; the determined key water quality environmental data variables and the fish healthy growth index are input into a predictive control model obtained after training, and the corresponding control amount is output. Accordingly, the interaction mechanism between the water quality environmental data variables and the fish growth state is explored, by constructing the predictive control model between the water quality and the fish growth, the water quality environmental parametersfor the healthy growth of the fish are dynamically adjusted to ensure the stability of the water environment, the consumption of resources is lowered, and the economic benefits of aquaculture are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of aquaculture, and in particular to an optimal control method and system based on a fish growth model. Background technique [0002] With the continuous growth of population and the increasing constraints of resources and environment, promoting green development and efficient and intensive use of natural resources have become the main goals of current agricultural development. As a new farming model, industrial aquaculture breaks through the drawbacks of traditional farming methods. Fully automatic monitoring and processing of water quality parameters, sewage treatment, disease prevention and other processes in the whole process of aquaculture production reduces the risk of aquaculture and improves economic benefits. [0003] Water quality is an important part of aquaculture. With the aggravation of environmental pollution, aquaculture needs the help of regulation technology to im...

Problems solved by technology

At the same time, changes in some water environmental parameters, such as the consumption of dissolved oxygen in the water, the increase of ammonia nitrogen and carbon dioxide emissions, lead to the continuous deterioration of water quality.

An unhealthy water environment will have a negative impact on fish feeding and growth behaviors, and thus cannot make fish grow healthily
