Study On PLC Fertilization And Technology Based On Fuzzy Control

Establishment Agriculture is using some equipment to enclose an interspace, forming a semi-close system. The system provides with more feasible climate condition, which accelerating plant or animals growth and so that output enhanced.Establishment Agriculture consists of two parts. One is established planting, the other is established breeding. In the field of established planting, micro-spray technology makes a promotion to fertilization methods, so-called fluid fertilizing technology. This kind technology dissolves the nutrient plant needed into water and gets original liquid. When fertilizing plant, we only need to adjust thickness with water and fertilize by micro-spray. These must be helpful to plant growth, so getting mixture is key of the micro-spray autocontrol.Comparing autocontrol model with manual work, there are many advantages, such as save water, fertilizer, energy, pesticide, physical force and so on. In addition, autocontrol model can avoid disbennifit infection by human factors, improve operate veracity. Moreover , the model is good for scientific management and advance technic spread.this paper embarks from development of modern establishment agriculture, introducing detailedly about the mixture technology in the autocontrol spray system. Considering the fact of this field, I put forward utilizeing Fuzzy control to solute mixture online. Particularly introduce the comprising of Fuzzy controller, and design experiment to prove controller rationality and get reasonable sample time.According to the result, this system works well, attaining expect.
