摘　　要：设计了一种基于模糊控制的灌溉施肥系统。运用物联网技术构建无线传感器网络,采集作物生长区的温度、湿度和光照强度数据,通过在线可溶性盐浓度(EC)/p H传感器实时监测灌溉施肥系统的主要参数,经模糊决策后,上位机发送控制指令给下位机,由下位机控制灌溉施肥系统工作,实现不同营养液浓度、不同灌溉模式的灌溉施肥所需营养液的精准调配。An irrigation and fertilization system based on fuzzy control was designed. Using lnternet of things technology to construct wireless sen- sor network, collecting data of temperature, humidity and intensity of illumination in crops growth zone, the main parameters of irrigation and fer- tilization system were monitored through online EC/pH sensor. After fuzzy decision, the master computer sends control commands to the slave computer, the slave computer controls the irrigation and fertilization system to realize the precise allocation of nutrient solution for irrigation and fertilization with different nutrient concentrations and different irrigation modes.
