基于光纤光栅应变传感器的监测系统设计

通过在桥梁、建筑等重大工程结构的具体实施应用中，对光纤光栅工程结构应变长期监测系统的设计方法、基本构成、传感网络的优化、系统的温度补偿、现场传感器的布设、保护工艺等诸多重要问题进行了分析和研究，并加以解决。应用此系统对大型重量级工作制钢吊车梁的加固进行了监测，通过与理论的对比表明采用光纤光栅应变传感网络对大型构件实现应变检测是可行的。

Design of Monitoring System Based on Fiber Bragg Grating Strain Sensor

In the process of the application of the sensors in bridges, architectures and other critical engineering structures, systematic analysis is made on the key problems, such as the devise of FBG long-term strain monitoring system, basic structure, optimization of sensing network, temperature compensation of the system, layout of sensor and protecting crafts. The system designed is applied to monitor the strengthening of the large crane beam. It is feasible to monitor the large structure with the scheme of FBG strain sensor by contrast to the theory.
