【摘要】：为解决双环入渗仪只能测定原状土的渗透速度,而无法测定原状土入渗湿润锋的运移规律和入渗过程中不同高度的土壤水分含量等问题,提出了一种基于频域反射法土壤水分传感器测量原状土入渗湿润锋运移规律和不同高度土壤水分含量的方法,采用arduino mega 2560单片机开发板采集土壤水分传感器检测得到的数值,设计了圆盘式底座的原状土入渗性能检测装置,土壤水分传感器安装在检测装置上,arduino mega 2560单片机开发板能够根据检测得到的数据判定原状土入渗湿润锋的运移的位置,并根据控制策略驱动检测装置,使土壤水分传感器进入下一位置进行检测,也能够对原状土入渗过程中不同位置的土壤水分含量进行连续检测。为研究原状土的入渗过程中湿润锋的运移规律和水分迁移提供参考。
[Abstract]:In order to solve the problem that the infiltration velocity of undisturbed soil can only be measured by double ring infiltration instrument, but the migration law of wetting front and the soil moisture content of different height in infiltration process can not be measured, etc. A method based on frequency domain reflection method is proposed to measure the moisture front migration law and soil moisture content of different heights in undisturbed soil. The values of soil moisture sensor are collected by using arduino mega 2560 single chip computer development board. A device for detecting the infiltration performance of undisturbed soil with disc base is designed. The soil moisture sensor is installed on the, arduino mega 2560 single chip computer development board to determine the position of the wet front movement of the undisturbed soil based on the measured data. According to the control strategy, the detection device is driven to make the soil moisture sensor enter the next position to detect, and the soil moisture content in different positions in the infiltration process of undisturbed soil can also be continuously detected. It provides a reference for studying the migration law of wetting front and water migration in the infiltration process of undisturbed soil.
