    摘要: 本文介绍了一种冻土及干土层自动观测仪器,仪器采用控制处理单元,频率采集单元和温度采集单元;频率采集电路采用硬质电路板,电容和温度采集单元采用柔性电路板,地温和土壤水分含量是仪器直接测得,冻土和干土层厚度是这两个变量通过数学算法求得,根据土壤含水量及温度,自动判断土壤某层是否冻结、是否为干土,并实现连续自动观测。 This paper introduces a permafrost soil and dry automatic observation instrument. The equipment used control unit, temperature acquisition unit and frequency acquisition unit. A frequency acquisition circuit board with a hard, capacitance and temperature acquisition unit uses flexible circuit boards. Mild soil moisture instrument is measured directly, frozen soil and dry soil thickness of these two variables is determined by a mathematical algorithm. Based on soil moisture and temperature, it determines automatically whether a certain layer is frozen soil or dry soil, and continues automatic observation.
