摘要
提出了一种新颖的、利用多模光纤缠绕钢绳式的传感阵列网络,对智能材料与结构的受力、应变等状态参量进行了监测和估计,并采用了光时域反射技术实时处理并行分布式传感信号,给出了测试数据、识别结果。
Abstract
A novel sensor array made of multimode optical fibers twisting steel strands is presented. It can be used to detect many state parameters such as load,strain of intelligent material and structure. Optical time-dimain reflectometry (OTDR) technology is applied to process real-time parallel and distributing sensing signals. In this way, the measured datas are obtained and the identified results are proved.
