Performance Study of a Wireless Structural Monitoring System
In this paper, performance of an academic wireless monitoring system is assessed by lab and field experimental studies. Acceleration responses collected by the wireless sensing units are compared with those obtained by a traditional wire-based data acquisition system. Beacon based clock synchronization in the wireless sensing is tested. The local computational capacity of the wireless sensors is also validated. Based on the benefits of low cost and easy installation, the wireless monitoring system is applied to the identification of structural modal parameters. It is shown that ambient vibration acceleration signals collected by the wireless sensing units can be used to perform a complete modal identification of instrumented bridge.
