摘要:

utoCAD软件作为目前世界上应用最广泛的工程与研究绘图平台之一,在矿业领域具有重要的应用价值。为完善自主研发的采空区三维建模可视化集成系统的功能,进一步提高其应用价值,在分析AutoCAD通用dxf格式文件的数据储存结构和总结不同图元要素数据存储规律的基础上,开发了采空区三维建模可视化集成系统的CAD数据接口,实现了集成系统对采空区扫描点云模型、空区剖面和三角网格实体模型dxf文件的数据读取以及采空区三维点云模型、空区剖面和三角网格实体模型dxf文件的自动生成。实用结果表明,所开发的软件接口成功地实现了集成系统与AutoCAD的数据对接,从而为矿山开展采空区周边相关开采工程的设计带来极大的方便,也为其他CAD接口技术的研发提供有益借鉴。

Abstract:

As one of the world’s most widely used drawing platform in engineering and research field currently,AutoCAD software has the significant value in mining field.In order to improve the function and application value of 3D Modeling Visualized Integrated System of Goaf which was developed independently,CAD data interface of the integrated system was developed on the basis of researching the data storage structure of dxf file used universally by CAD and summarizing the data storage rule of different graphic elements.Through the interface,the data in dxf file about goaf’s point cloud model,profile and triangular mesh entity model could be read by integrated system.At the same time,the dxf files about goaf’s point cloud model,profile,and triangular mesh entity model could be generated automatically.CAD Data Interface effective development methods was presented,data storage structures of different graphic dxf file was parsed,store law of different data elements in the dxf file was summarized.The practical application showed that data sharing between the integrated system and AutoCAD was well realized through this interface,so great conveniences could be brought in the work surrounding goaf,like relevant mining design.And this achievement can provide useful reference to research on the CAD interface.

Key words: goaf , 3D modeling, visualized integrated system, CAD data interface, development
