Research And Realization Of Integrated Intelligent Control System Of Solar Greenhouse In Alpine Region

With the continuous improvement of Chinese people’s living standards,people to the consumption and quality of vegetables and fruits requirements is more and more high,the northern alpine winter and spring vegetable supply almost all rely on solar greenhouses,Jiuquan Gobi unique photo thermal and climate conditions to mainly solar greenhouses Gobi modern agriculture booming.In view of the limitations and deficiencies of the traditional control technology and monitoring system of solar greenhouse.How to scientifically monitor and adjust the environmental parameters in the greenhouse reasonably and accurately according to the needs of crops has become an important problem to be solved.In this paper,a solar greenhouse integrated control system is designed with a multivariate intelligent control strategy of greenhouse environmental parameters,which mainly includes three aspects: field monitoring system,mobile phone cloud service system and intelligent control strategy.First,the requirements for various crop greenhouse environmental factors are introduced at different growth stages,and the technical scheme and overall design of the whole control system are given.Secondly,combined with fuzzy and fractional PID control technology,a temperature and humidity controller is constructed based on the fuzzy fractional PID,which the temperature and humidity of fuzzy fractional PID were constructed for modeling and analysis under MATLAB environment.Then,the whole control system hardware selection,as well as software design and program debugging.Finally,the integrated intelligent control system of solar greenhouse is built to test and analyze the control performance of the system environmental parameters,under the requirements of the environmental parameters for hot pepper and tomato.Data show that the system can achieve more accurate automatic adjustment of greenhouse environmental parameters,to meet the optimal growth needs of crops,improving the convenience and safety of equipment handling,shortening the growth and harvest cycle of fruits and vegetables while helping farmers to increase production and income.Remarkable achievements in the "energy conservation and emission reduction " and " carbon neutrality" exploration.
