摘要
以Imote2无线通信平台为核心,构建新一代无线加速度节点;将无线通信、信号预处理、数据运算以及电源管理在节点内部完成,减少无线通信数据量,降低传感器运行功耗;以润扬大桥原有有线加速度节点为测试参考对象,通过现场试验,比较研究无线加速度节点和有线加速度节点在系统构架、数据采集、数据传输、数据精确度等方面的表现,验证无线加速度节点在桥梁振动监测应用中的可行性。
The next-generation wireless acceleration node was designed with a new wireless communication platform Imote2 as the core. The amount of transmitted data and the power consumption were reduced by integrating wireless communication,signal pre-processing,data analysis and power management in the node. Taking the wired acceleration node of the original vibration monitoring system in the Run-yang Yangtze River Bridge as a reference,a field experiment was conducted to compare the system architecture,data acquisition,data transmission and data accuracy of the wrieless acceleration node with those of the wired ac-celeration node. The result shows that wireless acceleration node is quite promising in the bridge vibration monitoring applications.
