近些年,随着桥梁建设数量的不断增多和形式的多样化,桥梁的结构安全成了桥梁建设的关键问题,而用来确保桥梁结构安全的健康监测技术也成为当前的热点研究课题。其中,桥梁结构健康监测系统及无线传感技术具有传感节点体积小、计算能力有限、成本低等优点,可以大大提高此系统可靠性、缩短其安装的周期以及有效的降低建设成本。但是就现在的桥梁结构健康监测的无线传感技术来看还不是很成熟,因此研制开发出适用于此监测的无线传感器具有至关重要的现实意义。本文主要概述了当前的桥梁结构健康监测系统和无线传感技术的发展现状,并基于此设计了无线结构健康监测的网络架构。
In recent years, with the increasing number of bridges and the diversification of forms, the structural safety of bridges has become a key issue in bridge construction. The health monitoring techniques used to ensure the structural safety of bridges have also become the current hot research topics. Among them, bridge structure health monitoring system and wireless sensing technology have the advantages of small sensing node size, limited computing power and low cost, which can greatly improve the reliability of the system, shorten the installation period and effectively reduce the construction cost. However, the current wireless sensor technology for bridge structural health monitoring is not yet mature, so it is of crucial practical significance to develop a wireless sensor suitable for this monitoring. This paper summarizes the current status of the bridge health monitoring system and wireless sensor technology, and designs the network architecture of wireless health monitoring.
