基于BIM-SHM的大跨度钢结构实时感知预警系统研究

摘要

针对目前大跨度钢结构健康监测的实时性与可视化水平不高,安全隐患的位置信息无法快速定位,以及单指标预警不准确等问题,构建基于BIM-SHM的大跨度钢结构实时感知预警系统,该系统主要包括WSN数据采集与传输模块、数据库模块、基于SHM的BIM二次开发插件以及预警功能模块.然后阐述实时感知预警系统开发与工作流程,以期实现大跨度钢结构安全状态的实时感知预警.%Aiming at the problems of the current situation that the real-time performance and visualization level of health monitoring is not high,the location information of the hidden danger cannot be located quickly,and single index of early warning is not accurate for large-span steel structure,the paper builds a real-time monitoring and early-warning system for large-span steel structure based on BIM-SHM,which includes WSN data acquisition and transmission module,database module,plug-in of secondary exploration for SHM base on BIM and early warning function module. Then,expounds the development and working process of real-time monitoring and early-warning system,in order to achieve real-time sensing warning of large-span steel structure.
