摘要
为解决传统设施蔬菜种植由于灌溉技术落后导致的水资源利用系数低,灌溉效果不理想等问题,采用LabVIEW平台设计了一套基于模糊控制的设施蔬菜智能灌溉控制系统。以土壤水势为基础搭建无线传感网络获取土壤信息,融合3G网络构建集现场集控计算机和远程监控中心相结合的无线监控网络体系。采用实时土壤水势与理想水势差值以及差值变化率作为模糊控制系统输入,根据模糊控制算法得出最佳灌溉时长。经测试该系统可以在无人值守下完成对作物的精准灌溉,农户远程也能实时监测田间数据和进行灌溉控制。
In order to solve the problems of low utilization coefficient of water resources and unsatisfactory irrigation effect caused by backward irrigation technology in traditional facility vegetable planting,an intelligent irrigation control system for facility vegetable based on fuzzy control was designed on LabVIEW platform.Based on the soil water potential,a wireless sensor network was built to acquire soil information,and a wireless monitoring network system constructed by on-site centralized control computer and remote monitoring center was built combining 3G network.The difference between real-time soil water potential and ideal water potential and the change rate of the difference were used as the input of the fuzzy control system,and the optimal irrigation time was obtained according to the fuzzy control algorithm.After testing,the system can complete precise irrigation of crops under unattended condition,and farmers can monitor field data and control irrigation in real time remotely.
