基于对农业大棚环境特点的分析,研究农业大棚控制系统的总体设计方案。为了减少环境的耦合、强时滞、非线性和不确定等因素的影响,运用模糊控制算法列出输出设备的控制规则,并设计出基于嵌入式系统的监测软件,从而达到调节温室环境的温湿度、二氧化碳浓度、光照强度等因子的目的,使农作物处于最佳或相对最佳的生长环境条件中。实验结果证明了整个方案的可行性和相关算法的有效性。
Based on characteristics analysis of agricultural greenhouse environment,the overall design of agricultural greenhouses control system has been studied. To reduce environmental impact of coupling,strong delay,nonlinearity,uncertainty and other factors,fuzzy control algorithm is used to list control rules in output device,and monitoring software based on embedded systems is designed,so as to achieve the object of the temperature regulating greenhouse environment,humidity,carbon dioxide concentration,light intensity and other factors,so that crops are kept in the best or relative optimum environment conditions. Experimental results showthe feasibility and effectiveness of algorithms related to the entire program.
