| Some advances in extensive bridge monitoring using low cost dynamic characterization Struc-tural Health Monitoring (SHM) systems have excellent potential to improve the regular operation and mainten-ance of the structures. Wireless Sensor Networks (WSN) have been used to avoid high cost of traditional ge-neric wired systems. The most important limitations in SHM wireless systems are time synchronization accuracy, scalability and reliability. In this article, a complete wireless system for structural identification under environmental load is presented. Our contribution ranges from the hardware to the graphical front-end. The system is paying attention in avoid-ing the main limitations of WSN for SHM specially focused in reliability, scalability, and synchronization. In order to validate the system we have carry out different tests: check synchronization at the lab, compare our operational modal analysis over a real bridge with a numeric analysis and analyze the results of a comparison between couples of signals which belong the same position over the bridge. Obtained results have been excel-lent and the system has been validated. | |
