Paper Abstract

Based on optical fiber grating sensing technology,the bridge bearing displacement was monitored for a long term online.The sensor performance and its installation method were analyzed.The structure of the monitoring system was studied,the data acquisition system was realized.The 3G network which transfered the data remotely and data storage method were discussed to build a remote data center. The composition of the database was proposed, and the relation between the displacement and the temperature for the bridge bearing was discussed on the historical data.The basis on the bridge safety monitoring was provided.
