Research On Key Technologies Of Dissolved Oxygen Intelligent Control Of Circulating Water Aquaculture Environment

With the rapid development of the Internet of Things industry and the continuous improvement of aquaculture intelligence level,my country has also proposed the "Blue Granary Plan" to start the development of marine fishery.In recent years,a variety of new aquaculture models have emerged,my country’s industrialized circulating aquaculture models have developed rapidly,and aquaculture technology has also developed rapidly.The realization of intelligent monitoring of the water quality environment in the aquaculture process has become the current research The key point is that this paper studies the key technologies of intelligent control of dissolved oxygen in circular aquaculture were studied,and the prediction model and regulation model of dissolved oxygen in ponds based on intelligent algorithm were established,and designs a set of dissolved oxygen monitoring system for circulating aquaculture ponds.It can well realize the environmental monitoring function in the aquaculture process,and promote the better development of my country’s aquaculture industry toward the direction of intelligence.This paper takes the dissolved oxygen concentration in the circulating water aquaculture environment as the research object,and uses intelligent algorithms to establish a pond dissolved oxygen prediction model and control model.The main research contents are as follows:(1)In order to understand the distribution of dissolved oxygen in circulating water aquaculture ponds,this paper studies the conversion mechanism of dissolved oxygen in ponds,and at the same time establishes a spatial sequence distribution model of dissolved oxygen in circulating water aquaculture ponds based on the conversion mechanism using mathematical theory,and realizes it with the help of mathematical software Model verification.(2)The factors affecting the prediction of dissolved oxygen in ponds were analyzed,and the genetic algorithm BP neural network model was introduced.At the same time,through the analysis of the classic algorithm,the algorithm correction scheme was proposed,and the pond dissolved oxygen was established based on the revised model.Time series forecasting model.The experimental results show that the revised model can well realize the prediction of dissolved oxygen in circulating water aquaculture ponds.(3)The fuzzy PID control system is studied,and the shortcomings of the control system are analyzed.The modified particle swarm algorithm is used to optimize the control system,and based on the optimized fuzzy PID control theory,a recirculating water aquaculture pond solution is established.Oxygen control system.The model was verified by simulation software,and the results showed that the modified model of pond dissolved oxygen regulation has a good control effect.(4)For circulating water aquaculture,a water quality monitoring system with STM32 as the core was designed,including the overall structure design,selection of sensor,hardware circuit design and monitoring cloud platform design,monitoring and control system for the circulating water pond aquaculture water quality in the process of information and the synchronous data acquisition of meteorological information and implements the environmental information of remote monitoring and control dissolved oxygen.
