基于BIM轻量化技术和物联网的基坑监测信息可视化应用

摘要  为了解决基坑监测中存在的数据反馈不及时及可视化功能过度依赖原生软件二次开发等问题,借助BIM轻量化技术和物联网设备,将基坑监测信息在线可视化,实现了对基坑工程施工过程的实时监测与预警。首先,利用Autodesk Revit软件建立基坑的BIM模型,并采用轻量化技术将其在网页端展示;其次,利用物联网设备对基坑各项监测指标进行数据采集,并将数据实时传输至服务器,以便前端网页按需调用数据库中的监测数据;然后,将监测点对应的监测数据与引擎功能的POI相关联,实现监测数据与POI的绑定;最后,设置不同安全状态的监测阈值,当监测数值超过报警阈值时,系统将自动触发报警机制,并将警报信息推送给相关施工管理人员。该研究不仅能够提高基坑监测的精度和实时性,同时也为施工管理人员提供了及时的预警信息,有助于降低施工风险,保障工程的安全与可靠性。To address the issues of untimely data feedback and excessive reliance on secondary development of native software for visualization in excavation monitoring,BIM lightweight technology and IoT devices are employed to achieve online visualization of excavation monitoring information,enabling real-time monitoring and early warning during the construction process of excavation.Firstly,the BIM model of excavation is established using Autodesk Revit software,and lightweight technology is applied to display it on a web platform.Secondly,IoT devices are utilized to collect data on various monitoring indicators of excavation,and the data is transmitted to the server in real-time,allowing the front-end webpage to retrieve monitoring data from the database as needed.Thirdly,the monitoring data corresponding to the monitoring points are associated with POI within the engine functionality,achieving a binding between the monitoring data and POIs.Lastly,monitoring thresholds for different safety states are set,and when the actual value exceeds the alarm threshold,the system automatically triggers an alarm and pushes the alarm information to relevant construction managers.This research not only enhances the accuracy and real-time nature of excavation monitoring but also provides timely early warning information to construction managers,which is beneficial to reduce construction risk and ensure the safety and reliability of the project.
