为提升水稻含水率在线检测的精度,本文提出了一种适用于谷物仓或干燥仓的阵列棒式电容传感器结构及其水分检测方法.使用COMSOL Multiphysics 6.1软件对平行电极棒式电容器进行了静电场模拟仿真,通过调整其物理参数探究电极棒长度、半径、轴间距与电场边缘效应的变化关系.以电容器灵敏度作为试验指标,使用Design-Expert 13.0软件对平行电极棒电容器的长度、半径、轴间距进行三因素三水平Box-Behnken响应面试验设计,通过方差分析和响应曲面分析得到最优的电极棒结构尺寸参数,最后将其扩展为电极阵列.研究表明:在满足装置机械设计要求情况下,电极棒长度63.480 6 mm,电极棒半径1.449 34 mm,电极棒的...

To enhance the accuracy of online moisture content detection in rice,this paper proposes an array rod-type capacitive sensor structure suitable for grain or drying silos,along with a moisture detection meth-od.Using COMSOL Multiphysics 6.1 software,a static electric field simulation of parallel electrode rod ca-pacitors was conducted.By adjusting physical parameters,the study explored the relationship changes be-tween electrode rod length,radius,inter-axial distance,and the edge effects of the electric field.The sensi-tivity of the capacitor served as the experimental indicator.Using Design-Ex...
