光纤光栅（FBG）传感器在尾矿库在线监测中的应用

摘要

光纤光栅（ FGB）传感器已经广泛应用于水利工程监测中，在尾矿库在线监测系统中的应用也在逐步增多。为提高某尾矿库在线监测系统的抗干扰和运行稳定性，某尾矿库在线监测系统工程采用以光纤光栅传感器作为主要采集设备。应用结果表明：光纤光栅传感设备的突出优点是运行稳定性好、抗干扰能力强，测量精度满足使用要求；明显不足是安装条件要求高，前期投入较高。%The Fiber-Bragg-Grating sensor has been widely used in water conservancy projects,and its application in online monitoring system of tailings pond is also increasing. In order to improve the stability and anti-interference ability of online monitoring system in tailings pond,FBG sensors were used as main collecting devices in an online monitoring system project. The results showed that the main advantages of FBG device is good operation stability, strong anti-interference ability,and the measurement accuracy can meet the use requirements. The obvious defi-ciency is the installation requirements are high,as well as the higher investment in advance.
