摘要
提出了一种基于Labview语言的实时数据采集及处理系统设计方案,介绍了光纤光栅温度传感波长解调原理,应用Labview语言编写了程序,实现对数据的处理和显示。试验结果表明:该系统能够有效利用计算机实现信号的处理,满足FBG传感器实时数据采集和处理的要求,获得了0.3℃温度测量精度和0.1℃分辨率。
Design of data acquisition system based on LabVIEW software have been presented in this paper, and the basic sensing principles of FBG sensor is produced, the data is also precesvsed and displayed by LabVIEW software. The experiment shows that the system effectively disposes of signal using computer, the need of the real- time data acquisition for FBG sensor, the temperatue measurement precisions of 0.5℃ and resolution of 0.1℃ are achieved.
