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.
