摘要
在实际工程结构的健康监测中,需要采集、处理大量的应变、温度等信息以提取各种健康监测所需的特征参量.为了有效监测结构的应变,利用光纤布拉格光栅(FBG)作为主要的传感元件,结合欧几里德最小距离算法等模式识别技术设计了结构应变监测系统,并利用该系统对壁板结构的应变分布情况进行了实际测试.实验结果表明,该系统能够较好实现对壁板结构的应变分布情况进行监测.
In the actual structttml health monitoring, it is necessary to aquire and process a lot of strain, temperature and other information to extract all kinds of characteristic parameters for health monitoring. In order to effectively monitor the strain of the structure, the structure strain monitoring system was designed using Fiber Bragg Grating （FBG） as the main sensor with Euclidean minimum distance algorithm. With the system, the experiment is carried to get the wall structure Strain distribution. Experimental results show that the system can fulfill the measurement and monitoring for the strain distribution of the wall structure.
