摘要
针对目前地铁车站深基坑开挖安全监控的实时性与自动化水平不高,数据传递严重滞后以及安全隐患的位置信息无法快速定位等问题,将无线传感识别(wireless sensor identification,WSID)技术与BIM技术有效集成,并以基坑内的钢支撑轴力为监测对象,构建了基于WSID与BIM技术的地铁车站深基坑钢支撑轴力实时感知预警系统。该系统包括了WSID数据采集与传输模块、数据处理与判断模块、BIM模块和预警反馈模块,实现了现场数据的快速采集、快速传输以及应急指令的快速反馈。
According to the current situation that the real-time performance and automation level of security monitoring is not high, the data transfer is seriously lagging behind, and the location information of the security hidden danger cannot be located quickly in the excavation of deep foundation pit of subway station, we integrate wireless sensor identification （WSID） with BIM technology, and propose a real-time monitoring and early-warning system for the axial force of steel support in deep excavation of subway station based on BIM and WSID. The system includes WSID data acquisition and transmission module, data processing and judgment module, BIM module and early warning feedback module, and we can realize the rapid collection of on-site data, rapid transmission and the rapid feedback of emergency command.
