【摘要】 针对节水灌溉受多因素影响难以建立精确控制模型的特点,开发了基于虚拟仪器平台的作物灌溉模糊决策控制系统。该系统由传感器、测量仪、数据采集卡、LabVIEW软件平台等组成,将土壤水势和作物腾发量作为输入量,采用Fuzzy Logic Control Toolkit工具包设计模糊控制器,建立多因素控制规则库,实现作物灌溉需水量的模糊决策。试验结果表明该系统界面友好,操作简单,能对作物需水量进行综合判断与决策管理,为节水灌溉提供科学的依据。更多还原

【Abstract】 Water saving irrigation is affected by multiple factors, and it is difficult to develop a precision control model. A fuzzy irrigation decision-making system was established by using virtual instrumentation platform. The system consists of sensors, test instruments, data logger board and LabVIEW software. The soil water potential and crop evaporation were taken as input variables, and the Fuzzy Logic Control Toolkit was adopted to design fuzzy controller and establish multiple-factor control regular database to make fuzzy decision for the crop water saving irrigation. The test results show that the system has friendly interface and is easy to use; it can give comprehensive judgement and decision-making, and can provide scientific basis for water saving irrigation.更多还原
