Self-Contained Sensor Skin for Highway Bridge Monitoring

摘要0529208孙勋卡内基梅隆大学拟议的研究目标是发展的基本概念，理论框架和实现技术的自包含传感器皮肤的背景下，桥梁结构安全监测。拟议的传感器皮肤将由（1）用于损伤诊断的有源传感贴片，（2）用于无线数据传输的RF收发器，（3）用于非接触式电力输送的嵌入式平面螺旋，以及（4）用于执行检查程序的无人机器人组成。所提出的传感器皮肤将被设计成不需要任何电池，也不需要任何电线来进行电力输送和数据传输。因此，传感器皮肤贴片可以以非侵入性方式容易地安装到桥结构的表面。一旦在检查机器人单元检索到数据，将开发概念和方法，以便在桥梁遇到的操作和环境变化的情况下，可以自主执行损坏诊断，而不依赖于先前的参考数据。最后，将通过桥梁结构的现场测试明确考虑在役桥梁所处的实际环境和运行条件。教育目标是将传感器和无损检测研究的结果与学生的教育经验相结合，通过将技术融入课程，少数民族学生的招募和推广活动。该项目得到了传感器倡议NSF 05-526的支持。

Abstract0529208Hoon SohnCarnegie Mellon UniversityThe proposed research goal is to develop the fundamental concepts, theoretical frameworks and implementation techniques for a self-contained sensor skin in the context of bridge structural safety monitoring. The proposed sensor skin will be composed of (1) active sensing patches for damage diagnosis, (2) RF transceivers for wireless data transmission, (3) embedded planar spirals for contact-less power delivery, and (4) unmanned robots for performing inspection routines. The proposed sensor skin will be designed so that it does not require any batteries nor have any wires for power delivery and data transmission. Therefore, the sensor skin patch can be readily mounted to the surface of a bridge structure in a noninvasive manner. Once data are retrieved at the inspection robot unit, concepts and methodologies will be developed so that damage diagnosis can be autonomously performed without relying on prior reference data in the presence of operational and environmental variations that bridges encounter. Finally, realistic environmental and operational conditions that in-service bridges are subject to will be explicitly considered through a field test of a bridge structure. The educational objective is to integrate the results of the sensor and NDT research with the educational experiences of students through integration of technology to curriculum, minority student recruitment and outreach activities.This project is supported under the sensor initiative NSF 05-526.
