摘要：

Due to the shortcomings of the existing vibration sensors which usually need signal relay transmission for large-scale network monitoring, a new type FBG-based vibration with less matched filtering process is designed which has a simple structure and convenient for production. The test results in lab show high signal-noise ratio and good consistent between response frequency and test frequency which can meet the bridge low frequency test requirement in-suit. Also the transmission reliability over a long distance and low order detection effect are verified by a real bridge monitoring results.
