基于虚拟仪器构建服装测量用温湿度仪

Development of the temperature and humidity instrument for clothing measurement based on virtual instrument

温度和相对湿度是服装热湿舒适性研究领域中2个重要的测量参数,对其进行精确的动态实时测量是服装领域的实用技术。以美国国家仪器(NI)公司的虚拟仪器为架构,在LabVIEW为系统软件的开发环境下,研制了1台温湿度测量仪。该仪器具有多路信号输入,数据连续采集与处理,图形化显示,文件存储,超限报警等多项功能,并具有设置灵活,方便修改的特点,可用于服装热湿舒适性测量及其他相关领域,并在实验中取得了良好的结果。

Temperature and relative humidity are two important parameters in research of thermal and moisture comfort properties of clothes, and making accurate and real-time measuring of them is a practical technology. This article introduces the temperature and humidity measuring instrument which is developed on NI virtual instrument technology and LabVIEW software. This instrument has many functions, such as multi-channel signals input, real-time data acquiring and processing, graphical display, file preservation, and overrun alarming. This instrument can be used in thermal-moisture comfort measurement of clothes and some other relative fields, which is flexible, versatile and obtains good results in experiments.
