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

Masanobu Shinozuka（Univ Calif/Irvine）本研究开发了一种用于多个无线和自供电传感器节点的传感和诊断平台，称为DuraNode，该平台由加州大学欧文分校的土木与环境工程系和电气工程与计算机科学系合作设计，组装，实验室和现场测试。 对一座既有桥梁的测试结果与传统的高精度压电传感器进行了对比验证。显著的成本效益使得能够制造和组装大量的DuraNode作为下一代SCADA（监控和数据采集）系统的原型，该系统预期用于空间分布的城市系统的控制，特别是公用事业系统操作。这个新版本的SCADA系统将开发的是这些城市系统的破坏定位和条件评估下的瞬态干扰，由于自然和人为hazards.Scientific优点：建议DuraNode为基础的平台允许无线数据采集，传输，处理，分析和决策都在实时。这是第一个已知的努力，将现有的结构监测技术转化为下一代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应急响应。更广泛的影响：作为这项工作的一部分，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/测试台提供基础，支持推广计划，以便在广泛的政府机构，从业人员和公众中传播结果，并允许代表性不足的研究生和本科生以及其他群体（少数民族和少数民族拥有的小型企业）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.
