摘　　要：本文介绍一种光纤机敏材料系统与结构.在材料与结构中埋入光纤传感阵列,通过对传感信号的神经网络处理,实现状态监测.基于光纤微弯传感原理,提出了一种适宜于此系统的光纤传感阵列结构,以及直接利用传感阵列光纤出射光的光强分布特性的神经网络信号处理方法.重点研究并给出了系统的结构及其功能,以及应用于混凝土构件的实验结果,验明了所提方法的可行性与有效性.On the basis of fiberoptic sensing array,embedded in material and structure,and neural network signal processing, a smart material system and structure for state monitoring is discribed.The fiberoptic sensing array of state monitoring based on microbend fiberoptic sensing principle, and neural network signal processing approach based on the outgoing light intensity distribution pattern of the sensing array is suggested. The structure, functions snd experiments results of the structural concrete members, in which the sensing array is embeded, are given and analyzed in detail. The feasibility and effectiveness of the sensing and signal processing method proposed by authors are verified by experiments.
