Studies on a New Wireless Structural Monitoring System and Methods for Structural Damage Detection

Abstract

工程结构的安全性日益受到关注,结构健康监测已经成为土木工程的一个重要研究方向。近年来,由于无线监测系统具有小型化、智能化、低成本、安装便捷等优点而成为了结构健康监测中的研究热点。美国斯坦福大学与密歇根大学联合研制的无线传感节点因具有计算功能强大、能耗低、多任务能力的特点而受到关注。本论文通过实验室实验和现场试验来研究这种无线传感节点的性能。对比了无线监测系统与传统有线采集系统采集的环境振动加速度时程。其次,研究了无线监测系统信号采集的时间同步问题。本无线传感节点具有在线计算功能,是一种智能的传感器。传感节点本身已具有在线计算测试信号快速傅立叶变换的功能。本论文在此基础之上,采用嵌入技术,在无线...As the researchers attach great importance to the structural safety, structural health monitoring (SHM) has already become an important research direction of civil engineering. In recent years, wireless monitoring system has been developed as a research hotspot of SHM with such characteristics as miniaturization, intelligence, low cost and installation convenience. The academic wireless sensing un...学位:工学硕士院系专业:建筑与土木工程学院土木工程系_结构工程学号:2005130258
