摘要
作物病害胁迫声发射技术是当前植保信息化研究的重要内容。该文在分析作物病害胁迫的程度与声发射、环境因子之间的关系的基础上,设计了基于作物病害胁迫声发射机理的精准施药模糊控制模型,提出了适用于现场环境的精准施药自学习模糊算法。并利用MATLAB对系统模型进行了仿真。结果表明,该模型可方便地控制系统的施药量变化,并能达到较满意的控制效果。该研究为作物精准施药的智能控制提供了一种新的控制思路及方法。
Acoustic emission technology of crop disease stress will be the important tendency of pesticide application information in the future.With analyzing relationships among crop disease stress degree,acoustic emission and environmental factors,precision spraying system based on acoustic emission for crop disease stress was designed in the paper.Self-learning fuzzy arithmetic for precision spraying to field was put forward.The model was simulated successfully with the Matlab platform.The result showed an expected effect for the spray rate control system.The study provided a new control strategy and method to realize intelligent control of precision spraying for crop.
