| 摘 要： | 以毛白杨叶片为研究对象,基于电容传感器原理进行叶片含水量无损检测系统的研究。设计以SPCE061A单片机为核心构成部分,利用电容传感器采集叶片含水量所对应的电容值,由c/f电路将电容值实时转换成频率值,最终利用频率与含水量之间的关系模型进行计算和显示叶片含水量的值。该系统实现了对毛白杨叶片含水量的实时快速测量,达到了无损检测叶片含水量的目的。

| Abstract: | With Populus tomentosa Carr leaf as study object,the research of system based on the capacitive sensor principle was introduced,which can obtain leaf water content non-destructively.SPCE061A as a core part was designed in this system.The idea was to use the capacitive sensor for obtaining capacitance value of leaf water content,the capacitance value can convert to frequency real-time by c/f circuit,finally the system use the regression model between frequency and water content to calculate and display the v... |
