项目摘要
Summary: The objective of this research is to develop an integrated structural health monitoring system that utilizes advanced sensing, micro-processing, digital signal processing, wireless communication and damage diagnostic methods. The current project customizes and implements state-of-the-art miniaturized sensor units using MEMS technology and advanced wireless data communication methods that employ up-to-date components and architecture. A structure with such a distributed "smart" sensor network is thought of as a "Wireless IP Cloud of Sensors". New micro-accelerometers of high resolution are developed allowing for measurement of high amplitude vibration (i.e., earthquakes) as well as low amplitude vibrations (i.e., ambient vibrations) integrated with advanced wireless communication technologies and embedded systems for structural health monitoring applications. The research team is collaborating with Sandia National Laboratory in developing MEM-based accelerometers manufactured simultaneously along side CMOS circuitry on one die coupling the computation and sensor. The goal is to change the practices from extensive cabling and high cost labor, equipment and maintenance to the instrumentation of inexpensive wireless embedded systems.The proposed damage assessment algorithms are to perform (a) system level screening for quick identification of deterioration or damage; and (b) global diagnosis for structural performance and damage location identification. Statistical signal processing, energy dissipation and filtering methods are utilized that enable the computations to be performed locally at the sensor unit. A prototype system is to be tested both in the laboratory and the field.Significance and Broad Impact: The technology developed under this proposal will enable practical, cost-effective, long-term and quick response assessment of civil structures that estimates the degree of damage or degradation. The information provided by the system is critical following catastrophic events for reducing fatalities and for timely closure or continued operation of essential facilities (hospitals, fire stations, etc.). The system will also enable reliable systematic maintenance to prevent catastrophic failures under long-term deterioration.
总结:本研究的目的是开发一个集成的结构健康监测系统,利用先进的传感,微处理,数字信号处理,无线通信和损伤诊断方法。目前的项目使用MEMS技术和先进的无线数据通信方法,采用最新的组件和架构,定制和实现最先进的小型化传感器单元。具有这种分布式“智能”传感器网络的结构被认为是“传感器的无线IP云”。开发了允许测量高振幅振动(即,地震)以及低振幅振动(即,环境振动),并集成了先进的无线通信技术和嵌入式系统,用于结构健康监测应用。 该研究小组正在与桑迪亚国家实验室合作,开发基于MEMS的加速度计,该加速度计在一个耦合计算和传感器的芯片上沿着制造。其目标是改变的做法,从广泛的布线和高成本的劳动力,设备和维护,以廉价的无线嵌入式systems.The建议的损坏评估算法是执行(a)系统级筛选,快速识别恶化或损坏;和(B)的结构性能和损伤位置识别的全局诊断。 利用统计信号处理、能量耗散和滤波方法,使得能够在传感器单元处本地执行计算。 原型系统将在实验室和现场进行测试。意义和广泛影响:根据本提案开发的技术将能够对民用结构进行实用、具有成本效益、长期和快速的反应评估,以估计损坏或退化的程度。该系统提供的信息在灾难性事件发生后对减少死亡和及时关闭或继续运营基本设施(医院、消防站等)至关重要。该系统还将能够进行可靠的系统维护,以防止在长期恶化的情况下发生灾难性故障。
