摘要：

Researchers at the University of Illinois at Urbana-Champaign (UIUC), the Korea Advanced Institute of Science and Technology, and the University of Tokyo have developed and deployed a network of wireless smart sensors on a bridge in South Korea to monitor its structural health.Dubbed the Illinois Structural Health Monitoring Project, the sensor network was designed to create a reliable alternative to traditional structure inspection techniques, which can be expensive and unreliable. The researchers' technology uses concurrent and distributed real-time processing to solve the issues of cost effectiveness and safety, which are problematic with traditional centralized approaches. "Our research in distributed structural health monitoring using wireless sensor networks overcomes these problems and promises a robust, significantly lower-cost safer alternative to traditional structure inspection techniques," says UIUC professor Gul Agha. The research also produced a customizable software framework, which makes the development of structural health monitoring applications easier. More than 40 institutions around the world are using the framework of sensors and software, says UIUC professor Bill Spencer.

2009年12月24日，美国伊利诺伊大学与韩国UIUC大学和东京大学的研究人员，在韩国南部的一座大桥上部署了一个无线传感器网络，通过将传感器节点置于一个具有较强磁性的盒子里并吸附在桥体上，用于不断地监测桥梁的质量状况。这是迄今无线传感器网络用于民用基础设施健康监测的一个规模比较大的系统。
这个项目的目标是通过使用分布式并行实时处理的技术，克服传统的集中式控制方式，实现一个更可靠的、低成本的可代替传统的结构监测技术。
