摘要

用手测渗仪测量土壤的压实阻力需要更多的时间和精力。研制了一种拖拉机液压辅助嵌入式微处理器式测深仪,使测深结果易于监控,减少人为误差。所开发的探深仪包括一个驱动系统,用于将探深仪探头以所需的速度推入土壤,一个传感器单元(称重传感器和超声波传感器)用于测量推动探头所需的力和穿透深度,以及一个数据记录系统。嵌入式系统由Arduino Uno单片机、I2C、WiFi模块、HX711放大器等组成。该系统能够测量深度为500mm的土壤穿透阻力为5000kpa。WiFi模块帮助将数据传输到Android移动应用程序。获取的数据还包括日期/时间参数以及从手机的GPS获取的经纬度位置。其性能评估基于传感器的特性,如精度,灵敏度,非线性和不可重复性。用自制系统和手持式数字穿透仪测得的锥指数值的平均和最大绝对变化分别为22.50%和27.88%。
