ObjectARX技术在城市地下电力管线可视化中的应用

Application of ObjectARX to the Urban Underground Electric Power Line Visualization

针对城市地下电力管线普查内业效率低,本文提出了基于AutoCAD平台下ObjectARX工具的电力管线普查智能可视化方法,对电力管线图形实体对象建立、电力管线文件数据图形转换、电力管线图形实体碰撞自动识别进行了研究,实现了应用电力管线图形表现、读取电力管线普查数据、避免可视化成图压线等功能,可为用户提供直观的电缆井位置、电缆段、设备、电缆井剖面等可视化信息,具有较大实用价值。

According to the poor effect on urban underground electric power line census office work,a design method based on AutoCAD platform for electric power line intelligence visualization with ObjectARX was presented. Several technologies were studied to solve the application of graphics performance,power line census data reading and drawing line without overlapping,such as the establishment of electric power line graphics entity objects,the graphic transformation of the electric power line file data and the automatic recognition of electric power line graphic entity collision. Finally,the electric power line intelligence visualization was realized,it could provide users with visual information such as cable well location,cable section,cable equipment,cable profile and so on. This application improved the efficiency of the electric power line survey and had great practical value.
