土壤水分监测传感器的分类与应用

Classification and Application of Sensor for Soil Moisture Monitoring

通过调研,收集了国内外主流的土壤水分监测仪器资料,分析了仪器测量原理、主要性能和技术参数,进行了类型划分,根据《土壤墒情监测规范》的要求和墒情监测系统建设需求,在类比分析的基础上,提出了适合国内实际情况的土壤水分自动化监测仪器的产品型式,为国内墒情自动测报系统仪器的选型提供参考依据。

Through investigation,we collected technical materials on mainstream monitoring instrument for soil moisture both at abroad and home.The paper makes an analysis of measurement principle,main performances as well as technical parameters,and makes type classification for the instruments as well.According to specification for soil moisture content monitoring and development demands of monitoring system for soil moisture content,a catalog of automatic monitoring instrument for soil moisture is put forward based on analogy analysis,so as to provide reference for instrument selection of domestic automatic system for soil moisture content data acquisition and transmission.
