无线传感网络技术及其在结构健康监控应用中的关键问题
Key Issues of Wireless Sensor Networks for Structural Health Monitoring
摘 要
无线传感网络是结构健康监控的支撑性技术之一，能够通过智能化、自组织的方式，将各种不同检测对象、不同工作原理的传感器节点连成网络，并具有数据融合处理功能。无线传感网络与结构健康监控结合的关键问题包括：兼容不同传感器的采样频率和运行模式问题、传输带宽和实时性问题，无线发射频率问题、拓扑问题，能量问题、以及不同应用要求下的数据融合等问题。在FP7“海上风力发电设备健康监控”项目中，讨论了上述问题。

Abstract
Wireless sensor networks(WSN) is one of enable technologies in the structural health monitoring (SHM). Through intelligent, self-organizing means, it will test a variety of different objects and different working principle of the sensor nodes connected into a network and integration with data processing functions. In this paper the key issues of WSN applied in SHM were discussed, including integration of different types of sensors with different operational modalities and sampling frequencies, issues of transmission bandwidth and real-time ability, the wireless transmitter frequency, topology, and data fusion and integration, energy saving and self-powering. In FP7 project ‘Health Monitoring of Offshore Wind Farms’ project, the above issues were explored.
