摘　　要：本文研究了一种基于光纤网络的结构承载位置判别的方法,分析了检测系统的工作原理,进行了光纤智能结构承载位置判别实验,作出光纤网络输出光强与加载量的变化曲线图并进行了分析讨论,实验数据与理论分析能较好地符合,结果表明这种承载位置的判别方法具有快速、准确和可靠的优点,为光纤智能结构的进一步应用提供了新途径。A method of load monitoring and judging in the smart structure based on the fiber optics is researched in this paper. The principle of detection and monitoring system for this optical smart structure is illustrated and the experiments of loading and damaged position judgment are conducted. The intensity signals which carry the information of the specimen such as load are recorded. After we analyze the elative curves, the conclusions are given. The experimental data and curves meet preferably to the analysis of theory. The system of monitoring and analysis is approved to be real-time, effective and reliable and the research in this paper offers a new way of application of the special optical intelligent structure.
