无线传感网络在桥梁健康监测中的新应用
|
摘要
无线传感网络近年来的持续发展为桥梁健康监控提供了可靠和高效的平台。采用最新的CC2530解决方案使得无线传感网络能以更小的体积和成本进行大规模部署,从而更有效地采集桥梁振动、形变等桥梁健康相关的各种信号。现有的传统回归分析数据处理技术较难实时处理海量的传感器数据,基于模式识别、数据挖掘的数据挖掘技术则可以发现数据与实体结构损伤间的潜在规律并指导桥梁维护。
Wireless Sensor Network(WSN) developed in last few years provides highly reliable and efficient data collecting platform in bridge-health monitoring.With the newest CC2530 solution,WSN node is small and cheap enough to be deployed in large scale to acquit various kinds of signals,such as vibration,deformation and other important parameters.Since large quantity of sensors are deployed,massive data can be analyzed in real-time with the help of data mining technology,it is possible to discover the potential relationship between raw data and structural failure which is valuable to guide the bridge maintenance.
