Design And Research Of The Piggery Environment Control System Based On Fuzzy Theory

With the development of the national economy,people demand for meat also increased year by year,in order to ensure sustained and healthy development of meat products,the country gradually increased the investment in pig farming industry,scale and intensive farming methods become an important development direction.Good breeding environment,appropriate temperature,appropriate humidity and other weather conditions can effectively improve the health status of pigs,reproductive capacity and the output of pork.Therefore,the environmental control of the breeding environment-piggery become the key factors which influencing the production of pork.Based on the fuzzy theory,build a piggery environmental control system platform;establish environmental regulation model,and carries on the thorough analysis and research.The main research work is as follows:First,introduce the composition and structure of piggery environmental control system;establish the climate computer of Big Dutchman as the core of the design scheme of the control system piggery.In-depth research and analysis on the hardware part of the system;this laid a foundation optimization for control system.Second,focus on the fuzzy theory and its application in the control algorithm in the environmental control system carried on the thorough analysis and research.Based on the law of conservation of energy;establish mathematical mode of the piggery environmental control system;simulation and verification temperature fuzzy controller.Finally,based on the simulation and verification of the piggery environment microclimate model,get the pigpen temperature simulation and the measured temperature difference within the error range can be accepted,the environment model can accurately simulate the piggery microclimate environment,temperature fuzzy controller as the core of environmental control system can effectively control the inner environment parameters,and verified in the simulation test,achieve the desired control objective.
