基于BIM和北斗卫星定位的路基连续压实信息系统研究

摘要

According to the application requirements of subgrade digital construction,the subgrade continuous compaction information system which supports the correlation and accurate correspondence of BDS(BeiDou Navigation Satellite System) and BIM(Building information model) was developed,the main functions of which include compaction data acquisition,dynamic monitoring and display of acquisition terminal software,resume from data break-point,compaction data shown in BIM on Web,statistical analysis of quality data,business report generation,and multi roller cooperative operation in process control.The conversion method between Beidou location coordinate and subgrade BIM detection unit can not only avoid secret coordinates being transmitted over the internet,but also implement the corresponding display of compaction information and model detection unit in a sectionalized and hierarchical form on BIM,which has the reference value for the combination of BIM and BDS.%针对路基数字化施工的应用需求,研发了支持北斗卫星定位与BIM(Building Information Modeling)关联和准确对应的路基连续压实信息系统.主要功能包括压实数据采集、采集端软件动态监测和展示、数据断点续传、压实数据在Web端以BIM形式展示、质量数据统计分析、业务报表生成、过程控制中多台压路机协同作业等.北斗卫星定位坐标与路基BIM检测单元之间的换算方法既能避免涉密坐标在互联网中传输,又能实现在BIM上以分段、分层的方式将压实信息与模型检测单元对应展示.该实现方法对BIM和北斗的结合使用具有参考价值.
