摘　　要：针对灌溉电磁阀不易建立精确数学模型进行控制和灌溉的非线性和时滞性,采用模糊控制技术,以超低功耗单片机作为控制核心,通过对土壤湿度和空气温度的适时检测,并将其模糊化,经模糊推理、解模糊获得相应的灌溉量。此系统采用太阳能供电技术,可以在电能缺乏的区域或边远地区实施节水灌溉,节约了能源和水,有效地提高了灌溉的自动化水平。It is not easy for an irrigation electromagnetic valve to build exact controlling mathematical model and the nonlinearity and a significant time delay of irrigation. Adopting fuzzy controllable technique. Making single chip with the lowest power consumption as controllable nucleus. Getting through timely detection for soil moisture and air temperature. Getting them fuzzification,passing through fuzzy reasoning, defuzzification and getting corresponding irrigation requirement. The system make use of the solar energy power supply technique. It can carry out water-saving irrigation at the shortage electrical energy of region and remote region. It not only save energy and water but also improve irrigation of automatic level.
