Research Plan for Sensor-based Infrastructure Systems toward High Safety, Security and Service

智能基础设施的设计、制造和建设是当今工程研究人员面临的最终挑战之一。因为它们构成了系统智能的本质，所以智能结构技术的核心之一是围绕着创新的传感器和传感器系统。结构健康监测是新型传感器技术的主要应用之一。事实上，近年来，日本日益老化的基础设施状况引起了人们的极大关注。这些担忧不仅适用于土木工程结构，如国家的桥梁、高速公路和建筑物，也适用于其他类型的结构，如国内外航空公司目前使用的老化机队。然而，智能结构的一个重要问题是处理密集的智能传感器阵列产生的丰富信息；因此，网络和信息技术成为关键领域。在本研究项目中，深入探讨了现代传感器和反馈控制等关键技术在工程系统设计和施工中的协同集成以及在城市基础设施系统中的应用和实施问题。还提出了实现这一目标的路线图。

The design, fabrication, and construction of smart infrastructures is one of the ultimate challenges to engineering researchers today. Because they form the essence of system intelligence, one of the cores of smart structures technology centers around innovative sensors and sensor systems. Structural health monitoring (SHM) represents one of the primary applications for new sensor technologies. Indeed, much attention has been focused in recent years on the declining state of the aging infrastructure in Japan. These concerns apply not only to civil engineering structures, such as the nation's bridges, highways, and buildings, but also to other types of structures, such as the aging fleet of aircraft currently in use by domestic and foreign airlines. However, an important issue to smart structures is dealing with the wealth of information produced by the dense array of smart sensors ; therefore, networking and information technology become crucial areas. In this research project synergistic integration of key technologies such as modern sensors and feedback controls for design and construction of engineering systems and issues on the application and implementation to urban infrastructure systems are deeply discussed. A roadmap towards the goal is also presented.
