介绍了Imote2高性能无线传感器的性能和特点,并利用Imote2建立了无线信号采集系统,解决了在数据采集和处理过程中传感器的时间不能同步等问题; 通过在钢管混凝土拱桥模型上的试验测试,得到了拱桥模型的动力特性,并和有线传感器的测试结果进行了比较,利用频谱分析技术和频率稳定图方法验证了试验结果的准确性。结果表明:Imote2无线传感系统能够成功应用在土木工程结构监测中。
Abstract:
The performance and characteristics of new wireless sensor node with high performances were introduced. The wireless signal sampling system using Imote2 wireless sensors was designed. The problems in data acquiring process were solved, especially in time synchronization. This sampling system was then implemented on a concrete-filled steel tubular arch bridge to identify its dynamic characteristics. The testing results were compared with those from wired sensor systems according to frequency spectral analysis and frequency stabilization. The results show that Imote2 wireless sensor system can be applied to civil infrastructure monitoring projects.
