基于传感器的结构健康监测技术

王 宗鹏, 栾 云斐, 李 鑫

摘要

当前,传统的结构健康监测(Structural Health Monitoring,SHM)技术正逐渐被最先进的智能监控系统和决策解决机制所取代,结构的可持续发展性进一步加强。损伤检测是SHM的重要组成部分,在智慧城市和大数据分析的时代,数据分析驱动的结构健康监测框架尚不成熟,实现高效率、实时在线损伤检测是一个亟待研究的重大问题。传感器系统对实时监测结构的损伤或衰退发挥着重要作用,先进的材料、设计工艺、传感器的长期传感能力、电磁干扰、传感器布置技术、数据采集和计算、温度、恶劣环境和能耗是与SHM传感器相关的重要问题。本文首先考察了当前SHM的研究进展,其次,综述了现有结构健康监测系统Civionics新学科研究中的各种传感器技术、传感器类别和传感器网络;最后,分析了前沿损伤检测技术中的挑战及开放的研究问题。
