基于LabVIEW的湿敏电容测试系统研究

摘要

本文研究的湿敏电容测试系统是用虚拟仪器技术组建的,将LabVIEW应用到湿敏电容测试系统中,实现对测试数据的采集、分析处理及显示.设计了通过串口方式对仪器进行控制,数据采集及对湿敏电容进行分选的方法.应用LabVIEW软件的测试系统能解决人员、时间、精度和稳定性等诸多问题,使工作人员能够通过电脑屏幕直观的看到测试结果,并将结果储存到电脑中自动分析.%The humidity sensor test system studied in this thesis is built up by the virtual instrument technology. LabVIEW is applied to humidity capacitor test system in this research, and data collection, processing, analysis and display are realized. The method of the instrument control and data collection through the serial port is designed. The LabVIEW test system can resolve many problems such as personnel, time, precision and stability, the operator can see the test result through the screen of PC monitor, and save the result into computer to analysis.
