Improvement of Wireless Structural Health Monitoring System And Study of Low Power Consumption

Abstract

建筑结构在长期使用过程中,由于受到外在环境以及建筑水平等不利因素的影响,不可避免存在安全隐患,严重威胁人们生命财产安全。因此,如何对建筑结构的健康进行实时监测并进行反馈成为土木工程的热门研究方向之一,所以建筑健康监测(SHM)在土木工程中显得意义重大。SHM是指利用现场的无损传感技术,通过对包括响应在内的结构系统特性分析,达到检测结构损伤或退化、制定延长结构寿命策略的目的。 Zigbee技术是基于IEEE802.15.4标准基础上建立起来的无线传感网技术,具有低复杂度、低功耗、低速率以及低成本等优点,在智能家居、医疗辅助和无线监测等领域得到广泛的应用。本文基于Zigbee技术基础上搭建无线传...Due to the impact of unfavorable factors, such as the external environment and the level of the construction, there exist security risk inevitably in the building structures after a long-time use , which threat to people's lives and property. Therefore, how to conduct real-time monitoring of the health of the building structure and feedback become a hot research in civil engineering, so the resear...学位:工学硕士院系专业:信息科学与技术学院通信工程系_通信与信息系统学号:2332009115281
