摘　　要：随着光纤智能结构的发展和广泛应用,对其健康状态的监控和掌握就显得尤为重要。本文设计了一种基于激光光源的光纤智能结构实时监控软件。该软件在光纤智能结构的实际监控中,能够实时显示光纤智能结构不同位置的状态变化曲线,绘制光纤智能结构的空间健康状态分布图,这些能够方便直观掌握光纤智能结构的健康状态。同时,软件采用了广泛应用于智能结构损伤定位与识别的人工神经网络方法,用此方法能够准确定位光纤智能结构损伤位置。实验结果表明,软件具有较好的性能,能够准确实时地监控光纤智能结构状态。Abstract A novel real-time monitoring and measuring system for the fiber intelligent structure based on laser light-source is introduced in this paper. It is more important to monitor the fiber intelligent structure＇s state w,hen the fiber intelligent,structure is used. The self-made software applied in Fiber Intelligent Structures can receive the information from the fiber intelligent structure and monitor the health state of the fiber intelligent structure in real-time, The real-time curve of the signals is ,displayed in this software, and this software can also show the graph of the health state of the fiber intelligent structure distributed in space at the same time. The curve and graph show the health state of the fiber intelligent structure in intuition. The method of artificial nerve network is used in this software to analyze the state of the fiber intelligent structure, and the exact damage positions can be found by this method which has been widely used in monitoring the fiber intelligent structure. Then, in order to assess this monitoring system, the loads experiments are carried out at different locations of the specimen; The results show that this system works well and the computer can make immediate and right analysis with the software. Thus. the system mentioned in this paper can work well in monitoring the fiber intelligent structure.
