根据空气、冰和水的电容特性差异,本文设计了一种新型的电容式冰层厚度检测系统.该检测系统应用了德国acam公司的电容数字转换器PS021,可以把电容式传感器采集到的电容信号转换成数字信号输出.黄河的现场实验数据分析结果表明,系统结构简单,可靠性高,可以应用于冬季河道冰层厚度及冰下水位的定点、连续自动测量.
According to the difference of capacitance of air, ice and water, this paper designs a new capacitance ice thickness detection system.The detection system uses the acam Corporation’s capacitance-to-digital converter PS021 of Germany, which can collect the capacitance of the capacitive sensor The signal is converted into a digital signal output.Experimental data analysis of the Yellow River shows that the system has the advantages of simple structure and high reliability and can be applied to the fixed point and continuous automatic measurement of ice thickness and ice level in winter.
