摘  要
 本文的主題是“基于LabVIEW技術濕度測量儀的設計，主要闡述了濕度虛擬測量的設計過程和測試。此測試系統(tǒng)所用的是NI公司的USB-6009采集卡，是基于LabVIEW8.5 平臺編程設計的。它具備如下功能：濕度檢測、標準輸出、建立濕度與時間關系曲線、濕度監(jiān)測報警（可調(diào)上下限）以及信號輸出、數(shù)據(jù)儲存。文章對上述的功能模塊進行了逐一分析，并進行了整個測試系統(tǒng)的程序調(diào)試與研究。本測試系統(tǒng)對環(huán)境溫濕度無要求。

 Abstract
 In this paper, the theme is " The Design of Virtual Humidity Instrument By LabVIEW".It mainly describes in high temperature the humidity virtual meauring syetem design process and testing. This meauring system is used in the company's  USB-6009 NI data acquisition card. It is a programming design wich is based on the LabVIEW8.5 express platform. It is equipped with the following features : humidity corresponding detection,standard output,the establishment of humidity and time cure,humidity monitoring and alarm(adjustable minimum and maximum levels)and signal output,data storage. In this paper the functions of each module above and the entire test system for program debugging and research is analysed. The test system of environmental temperature and humidity did not ask for.
