摘要
在简要阐述虚拟仪器技术Labview7.1和光纤光栅测温原理的前提下,介绍了一种基于虚拟仪器技术的光纤光栅温度传感系统,包括系统的硬件和软件结构。重点说明了如何利用虚拟仪器工作平台(Labview7.1)来实现数据的采集、处理、显示、保存以及查询等功能,从而快速、智能化地实现光纤光栅波长移位的检测,进而得到准确的被测对象温度曲线。该系统具有界面形象、操作方便、可靠性高、功能全和可扩展性强等优点。
As the virtual instrument technology Labview7.1 and the principle of the optical fiber grating sensing temperature were instructed briefly, the optical fiber grating temperature sensing system based on the virtual instrument technology was introduced, including the hardware and software of the system. The text focused on how to use the virtual instrument platform to realize the functions, such as data acquisition, processing, display, preservation and inquiry, so that the shift of the optical fiber grating＇s wavelength could be detected fast and intelligently. Thus the exact temperature curve of the measured object was able to be obtained. The system has a lot of advantages, such as Image interface, easy operation, high reliability, scalability and strong functionality.
