摘　　要：针对现有的悬杆测深技术存在水面信号获取准确性差,水底信号触发装置机械结构复杂或受测流环境干扰明显等问题,对通过模拟量电压识别水面信号和通过电机输出扭矩的变化得到水底信号的无传感器测深技术进行了研究,设计了基于Arduino平台的根据空气和水中电阻率不同获取水面信号的方案。利用ANSYS/LS-DYNA分析了碰撞过程并得出碰撞过程中悬杆加速度变化趋势和碰撞瞬间电机输出扭矩变化趋势,通过PLC监测伺服单元反馈模拟量变化值准确得到水底信号。实践证明,该技术能准确测深,已用于黄委中游水文水资源局各水文站的缆道吊箱测流系统。The existing suspension rod sounding technology has the problems of poor accuracy of the acquisition of the surface signal,complex mechanical structure of the underwater signal triggering device or obvious disturbance of the measured flow environment.Aiming at the above problems,the non-sensor sounding technique for obtaining the underwater signal through analog voltage identification of the surface signal and the change of the output torque of the motor was studied.Based on the Arduino platform,the scheme of obtaining the water surface signal based on the air and water resistivity was designed.The collision process was analyzed by ANSYS/LS-DYNA and the trend of the acceleration of the suspension rod and the torque of the instantaneous motor output torque during the collision process were obtained.The underwater signal was obtained accurately by PLC monitoring the feedback value of the servo unit.The practice has proved that the technology can accurately sound and has been used by each hydrological station of the Middle Yellow River Hydrological and Water Resources Bureau in ca-bleway hanging box flow measurement system.
