摘要
传统水稻智能灌溉方法因灌溉决策需兼顾能源成本,且采用传统控制方法,难以有效处理模糊信息,导致灌溉水利用效率与灌溉均匀系数偏低,为此设计融合光伏发电与传感器模糊控制的水稻智能灌溉方法。设计一种可在小范围内独立运行、配备储能模块的直流光伏发电装置,以此为水稻智能灌溉系统独立供电。在直流光伏发电装置供电的基础上,设计基于传感器模糊控制的水稻智能灌溉方案,利用土壤湿度传感器与模糊控制算法实现水稻的智能灌溉。灌溉实例测试结果表明,设计方法能够实现水稻智能灌溉,不仅适用于电网供电不稳定的偏远地区,而且能够实现精准自适应调节。设计方法的灌溉水利用效率达到1.735 kg/m3,说明设计方法下每立方米灌溉水转化为较多的水稻产量,也就是设计方法的智能灌溉能够有效节水,同时该值未超过2.0 kg/m3这一过度节水警戒线,说明设计方法不需要警惕是否因过度节水导致产量波动。设计方法的灌溉均匀系数整体高于0.85,表明其灌溉水量分布均匀,不存在局部积水或干旱区域,可有效避免因灌溉不均而导致的产量损失或水分浪费。
The traditional intelligent irrigation method for rice struggles to effectively process fuzzy information because it must consider energy costs in irrigation decision-making and relies on traditional control methods,leading to low irrigation water utilization efficiency and a low irrigation uniformity coefficient.Therefore,we designed a rice intelligent irrigation method that integrates photovoltaic power generation and sensor fuzzy control.Design a DC photovoltaic power generation device with an energy storage module that can operate independently in a small range,and provide independent power supply for intelligent irrigation of rice through the device.Design an intelligent rice irrigation scheme based on sensor fuzzy control,powered by a DC photovoltaic power generation device,and achieve intelligent rice irrigation using soil moisture sensors and fuzzy control algorithms.The irrigation case test results show that the design method can achieve intelligent irrigation of rice,which is not only suitable for remote areas with unstable power supply,but also can achieve precise adaptive adjustment.The irrigation water utilization efficiency achieved by this design method is 1.735 kg/m3,which means that each cubic meter of irrigation water can produce more rice yield under this method.In other words,this intelligent irrigation design method can effectively conserve water.At the same time,this value does not exceed the excess severe water-saving warning line of 2.0 kg/m3 indicates that there is no need to be overly cautious about whether yield fluctuations are caused by excessive water-saving when using this design method.The overall irrigation uniformity coefficient of this design method exceeds 0.85,indicating uniform irrigation water distribution without local waterlogging or arid zones,thus avoiding yield loss or water waste due to uneven irrigation.
