Multi-scale Smart Sensing for Monitoring Civil Infrastructure

持续实时监测我国民用基础设施完整性的能力可以降低维护和检查成本，同时为公众提供更多的安全。中间件服务和工具可以为全面实施SHM战略提供基础和关键技术，这些战略可以利用智能传感系统提供的机会。该研究的重点将放在开发一个基于集成中间件服务的系统上，该系统可以利用在多个尺度上感知的信息进行结构状态评估。为了使这项研究落地，英特尔最新一代嵌入式计算机Imote2将提供所使用的平台。综合研究计划有四个主要任务：(i)为Imote2平台开发具有多尺度传感器的集成传感器板；（ii）利用Imote2平台为民用基础设施系统构思、开发和实施软件服务和工具框架；（iii）开发可在智能传感器分布式计算环境中执行的新SHM算法；（iv）在实验室和现场环境中对开发的硬件和软件进行原型和测试。成功完成所提出的研究任务将在实现用于保护民用基础设施的密集智能传感器阵列的实际实施方面取得实质性进展。

The ability to continuously monitor the integrity of our nations civil infrastructure in real-time can reduce maintenance and inspection costs, while providing for increased safety to the public. Middleware services and tools can provide a fundamental foundation and a crucial technology for full-scale implementation of SHM strategies that can exploit the opportunities offered by smart sensing systems. The focus of this investigation will be placed on developing an integrated middleware services-based system that can utilize information sensed at multiple scales for structural condition assessment. To ground this research, the latest generation of embedded computers from Intel, the Imote2, will provide the platform employed. The comprehensive research plan has four primary tasks: (i) develop an integrated sensor board with multi-scale sensors for the Imote2 platform; (ii) conceptualize, develop, and implement software services and tools framework for civil infrastructure systems using the Imote2 platform; (iii) develop new SHM algorithms that can be executed in the smart sensors distributed computing environment; and (iv) prototype and test developed hardware and software in both laboratory and field environments. Successful completion of the proposed research tasks will make substantial strides toward realizing the practical implementation of dense arrays of smart sensors for protection of civil infrastructure.
