| 摘 要： | 作为一种绝对式传感器,波长调制式光纤Bragg光栅传感器对应变的响应为0.9pm/??。开发了基于可调谐F-P滤波器的检测仪器与计算机系统之间的实时监测系统。在对白泥井3号隧道的监测过程中,该光纤Bragg光栅传感网络实时监测系统实现了对来自隧道结构的应变状态的实时采集和描绘,并可以存储波长和应变数据以便后期查寻分析;借助分析光纤Bragg光栅传感器的应变图、三维应变图,为判断隧道二次衬砌的受力趋向提供参考。

| Abstract: | As an absolute sensor, the response to variation of strain of wavelength- modulated fiber Bragg sensor is 0.9 pm/????Wedeveloped real- time monitoring system between signal detecting apparatus based on tunable F- P filter and computer. During the pro-cess of monitoring in Tunnel 3 of BaiNiJing, the real- time monitoring system of fiber Bragg sensing nets realizes real- time gatheringand displaying of variation of strain in tunnel structure, And stores wavelength and variation of strain data in order to be queried andanalyzed later. We get to know the trend of strain in tunnel by analyzing curve of strain and 3- D curve of strain for fiber Bragggrating sensors. |
