Vibration monitoring sensor arrangement mode of large-span steel structure

The invention provides a vibration monitoring sensor arrangement mode of a large-span steel structure. Comprising a sensor system, a data acquisition and processing subsystem, a data transmission subsystem and an information analysis and monitoring early warning subsystem. The sensor system adopts a vibration fiber grating sensor, the advantages of small size, light weight, electromagnetic interference resistance and the like are utilized, the sensor system is installed at each measuring point capable of reflecting the overall condition in the steel structure, whether the steel structure is in a normal vibration state or not is judged through data measured by the vibration fiber grating sensor, and an actual steel structure model is tested. The result shows that the method can accurately identify and monitor the vibration condition of the common steel structure so as to judge whether the steel structure is in a safe state or not. 本发明提供了一种大跨度钢结构的振动监测传感器布置方式。包括传感器系统、数据采集与处理子系统、数据传输子系统、信息分析与监控预警子系统。传感器系统采用振动光纤光栅
