Wireless Sensor Network Based Bridge Monitoring System

Abstract:

This paper presented idea and implementation of efficient, reliable wireless bridge monitoring system. The system using Wireless Sensor Network to collect the related environment parameters (vibrations, temperature, humidity) and transmitting data to the main server. The system eliminates stand-alone laboratory benchtop equipment sets and cable-based, hard-wired sensor networking. Modern MEMS technology for vibrations measurement and integrated humidity/temperature sensors application for structural monitoring is presented. Data collected by the wireless monitoring system is compared to data from a traditional wired monitoring system. Both – traditional and wireless collected data that can be used to accurately identify modal frequencies and mode shapes of the bridge. Case study of the system on bridge located over Vistula river in Krakow is shown.
