SGER: Development of Next Generation SCADA Network for Spatially Distributed Civil Engineering Systems

0509018 Masanobu Shinozuka(加州大学/欧文分校)本研究开发了一个用于多个无线自供电传感器节点的传感和诊断平台，名为DuraNode，该平台由加州大学欧文分校土木工程与环境工程系、电气工程系和计算机科学系合作设计、组装并进行实验室和现场测试。利用一座既有桥梁的测试结果与传统的高精度压电式传感器进行了验证。巨大的成本效益使大量的DuraNode能够被制造和组装成下一代SCADA(监控和数据采集)系统的原型，预计该系统将用于空间分布的城市系统的控制，特别是公用事业系统的运行。将开发的这个新版本的SCADA系统是为了在自然和人为危险的瞬时扰动下对这些城市系统进行破坏定位和状况评估。科学优点：拟议的基于DuraNode的平台允许无线实时采集、传输、处理、分析和决策。这是已知的第一项努力，将现有的结构监测技术转变为下一代SCADA，用于评估结构损坏和生命线系统故障，以进行适当的维护和紧急反应。更广泛的影响：作为这一努力的一部分开发的研究基础设施将为在更大的工程社区内共享数据/模拟/试验台提供基础，支持在广泛的政府机构、从业者和普通公众中传播成果的外联计划，并允许代表性不足的研究生和本科生以及其他群体(少数族裔和小型少数族裔拥有的企业)作为主要合作伙伴参与。

Abstract0509018Masanobu Shinozuka (Univ Calif/Irvine)This research develops a sensing and diagnosis platform for multiple wireless and self-powered sensor nodes, named DuraNode, which was designed, assembled and laboratory and field tested at University of California, Irvine in collaboration between Departments of Civil and Environmental Engineering and of Electrical Engineering and Computer Science. The test results involving an existing bridge were verified against traditional high precision piezo-electric sensor. Substantial cost effectiveness enables a large number, say of DuraNodes to be manufactured and assembled as a prototype of next generation of SCADA (Supervisory Control And Data Acquisition) system, which is expected for use of control of spatially distributed urban systems, particularly utility system operations. This new version of SCADA system to be developed is for damage localization and condition assessment of these urban systems under transient disturbances due to natural and man-made hazards.Scientific Merits: The proposed DuraNode-based platform permits wireless data acquisition, transmission, processing, analysis and decision making all in real-time. This is the first known effort to transform existing structural monitoring technology into the next generation SCADA for assessing structural damage and lifeline system malfunction for proper maintenance and emergency response. Broader Impact: The research infrastructure developed as part of this effort will provide a basis for sharing data/simulations/test-beds within the larger engineering community, support outreach programs to disseminate results across a broad spectrum of government agencies, practioners, and the general public, and allow underrepresented graduate and undergraduate students and other groups (minorities and small minority-owned businesses)to participate as major partners.
