摘要

传感器作为结构健康监测的基本组成部分,一直是人们关注的热点。该文论述了传感器技术的发展,尤其是无线传感器及无线传感器网络技术。介绍了由UCBerkeley研发的无线传感器节点-MICA的软硬件系统,针对结构健康监测,在实验室中建立和开发了一个原型监测系统,将选用的无线传感器节点布置在实验室两层结构模型上,组成一个无线传感器网络。通过小振动台试验证明无线传感器是完全可以应用于将来实际结构监测系统中的。
As the basic components of the structural health monitoring system,sensor is always highly concerned by researchers.The development of the technology of the sensor is discussed,especially the emerging technologies of a network of wireless sensors are presented in this paper.A wireless sensor node developed by UC Berkeley is introduced.For the purpose of the structural health monitoring,a laboratory prototype is designed and developed based on the MICA motes.To demonstrate the feasibility and validity of the proposed system,wireless sensor nodes are deployed on a structural model,and the performance of the nodes is investigated through shaking table tests of a two story steel structure.Based on processing and analysis of the structural model parameters,the wireless sensor node is shown to be effective for health monitoring of structures.
