Study of automatic control and management system for sinking and floating aquaculture cages
摘要
Abstract
Aiming at the problem that the inclination angle is too large and easy to roll over when the sinking and floating aquaculture cages are sinking and floating.In this study,an automatic control and management system for sinking and floating aquaculture cages has been developed.The automatic control system of sinking and floating aquaculture cages is mainly based on PID control technology.To realize automatic control of the inclination angle of cages,the appropriate parameters of the PID control system which uses the inclination angle signal and control algorithm to adjust the actuator,are explored.The corresponding management system for automatic control of sinking and floating aquaculture cages has been developed.The main functions include:floating and sinking control,cage cleaning,GPS positioning,and camera cleaning,as well as underwater camera monitoring,water quality,flow rate,liquid level and pressure data monitoring,etc.After a series of experiments such as the buoyancy-gravity ratio of the cage,the water inlet diameter and diameter ratio of the adjusting buoy,the PID control,the suitable value of the buoyancy-gravity ratio of the cage is 1.2,the water inlet diameter and diameter ratio of the adjusting buoy is 0.03.The PID parameters are P:100,I:1 000,and D:0.In this study,the control and information of each module of the sinking and floating aquaculture cages were integrated into a set of system,which improved the performance of the automatic control system of the deep-sea aquaculture cages.The system can control the output in a timely and stable manner and achieve the stable sinking and floating of the aquaculture cages.The results of the research have certain theoretical and practical meaning.The automatic control system of deep-sea sinking and floating aquaculture cages is one of the important technical means to achieve the industrialization development of deep-sea aquaculture.The research methods and experimental results proposed in this paper provide important data reference and theoretical basis for the research and application of deep-sea sinking and floating aquaculture cages.关键词
