Multi-scale Smart Sensing for Monitoring Civil Infrastructure

实时持续监测我们国家民用基础设施完整性的能力可以降低维护和检查成本，同时为公众提供更高的安全性。中间件服务和工具可以为SHM战略的全面实施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。这项调查的重点将放在开发一个集成的中间件服务为基础的系统，可以利用在多个尺度的结构状况评估的信息。为了使这项研究接地，英特尔最新一代的嵌入式计算机Imote 2将提供所采用的平台。该综合研究计划有四项主要任务：（i）为Imote 2平台开发带有多尺度传感器的集成传感器板;（ii）使用Imote 2平台概念化、开发和实施民用基础设施系统的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;以及（iv）在实验室和现场环境中的原型和测试开发的硬件和软件。成功完成拟议的研究任务将朝着实现密集智能传感器阵列保护民用基础设施的实际实施迈出实质性步伐。

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.
