【摘要】 为了减少冬小麦灌溉中水资源的浪费,对其进行适量灌溉。使用单片机、传感器等硬件结合模糊控制理论组成控制系统,依据于长时间的灌溉经验以及影响冬小麦的内外在因素,对其灌溉时间进行决策。使用Mamdani模糊控制器,以土壤的湿度差值以及土壤湿度变化率作为模糊控制器的输入,灌溉时间作为输出构成模糊控制器。依据冬小麦的灌溉经验建立其模糊逻辑控制表。由于监控面积较大,因此使用4个节点处于4个方位分布检测数据,控制电磁阀开关以及使用一个基站进行数据处理总结,进而保证各处土壤湿度保持在最佳湿度。更多还原

【Abstract】 In order to save water and irrigate winter wheat with suitable irrigation amount,the fuzzy control system,which combines microcomputer,sensor and fuzzy control theory,is used to make the irrigation time decision based on the irrigation experience and the factors affecting the growth of winter wheat. In the system,the Mamdani fuzzy controller is used as controller,the soil moisture difference value and change rate are used as input,and irrigation time is used as output. According to the winter wheat irrigation experience,the fuzzy logic control table is established. Because the monitoring area is large,so the system uses four sensor nodes to collect soil moisture information in different azimuth and control solenoid valves,and also use a base station to summarize data,so as to guarantee the optimum soil moisture.更多还原
