【摘要】 根据农业节水灌溉的需要,设计了基于嵌入式的果树滴灌监控系统。该系统能够实时对果树生长环境(土壤含水量、光照强度和温度)进行实时检测,同时通过比较法和间歇滴灌法控制土壤水分含量在适宜生长水平。该系统使用嵌入式平台和无线通信模块,增强了数据处理能力以及实现了远程监控;利用EC-5电容式土壤水分传感器检测土壤容积含水量;选取砂壤土进行了滴灌实验。实验结果表明该系统控制土壤含水量的误差在±8%以内。更多还原

【Abstract】 The fruit trees drip irrigation based on the embedded monitoring system was designed according to the need of agricultural water-saving irrigation. The system could detect fruit trees growing environment (soil moisture content, light intensity and temperature) in real time, and control soil water content around appropriate growth level through comparison method and intermittent drip method. The system equipped with embedded platforms and wireless communication modules enhanced data-processing capacity and realized remote monitoring and control; it used EC-5 capacitive soil water content sensors to detect volumetric water content of soil; sandy loam was chosen for drip irrigation experiments. The experimental results showed that the system could accurately control soil water content, with error between ± 8%更多还原
