基于虚拟仪器的人工环境室温湿度测量

Measuring Temperature and Humidity of Artificial Environment Room Based on Virtual Instrument

在电力系统中,为了研究高压电气设备外绝缘特性,需要人工环境室的温湿度能精确测量。本文将虚拟仪器技术应用于温湿度测量中,以LabVIEW为软件开发平台,以计算机为核心,配上传感器、数据采集卡和相应软件,对人工环境室的温湿度进行实时精确测量,并将结果以图形和数字两种方式进行实时显示,而且还扩展了数据存储功能,显示了虚拟仪器技术在温湿度测量中应用的灵活性和其功能的强大。

In the power system, to study the outer insulative character of high voltage electrical equipment, it is necessary to precise measure the temperature and humidity of the artificial environment room. In this paper, virtual instrument technology be applied to measurement of temperature and humidity, and with LabVIEW as software platform, using sensor, DAQ card and corresponding soft- ware to precise measure the temperature and humidity of the artificial environment room on the basis of the computer, and showing the result by two kinds of figure and data, also expanding data saving function, indicating the flexibility and strong function of Ⅵ technology be applied to measurement of temperature and humidity.
