基于BIM的铁路信号室外设备布置与碰撞检测方法

Arrangement and Collision Detection Method of Railway Signaling Outdoor Equipment Based on BIM

分析了当前主流的BIM软件在铁路信号领域应用时存在的局限性,提出了一种基于线路中心线模型的铁路信号室外设备三维布置方法,相对于传统的手动放置方式,提高了铁路信号室外设备三维布置的精确度和效率,提升了BIM软件的专业针对性和智能化水平.为了检测室外铁路信号设备放置位置的合理性,提出了一种基于铁路建筑限界模型的动态碰撞检测方法,该方法不仅能够自动、高效、全方位地对某条线路的室外设备进行碰撞检测,而且可以有针对性地对局部或重点区域进行检测,为目前尚未解决的铁路信号设备碰撞检测问题提供了一种解决思路,进一步提升了铁路信号BIM设计的质量和效率.

The limitations of current mainstream BIM software for railway signaling are analyzed and a three-dimensional arrangement method of railway signal outdoor equipment based on the center line model of railway tracks is proposed.Compared with the traditional way of arranging the equipment manually,this method can improve the accuracy and efficiency of three-dimensional arrangement of signal outdoor equipment and helps improve the professional and intelligent level of BIM software for railway signaling.To check the reasonableness of the placement of railway signaling outdoor equipment,a dynamic collision detection method based on the boundary model of railway building is also proposed,which cannot only make collision detection on outdoor equipment along a line automatically and efficiently but also can make targeted detection locally or in key areas,providing a solution to cope with the current problem of collision detection in railway signaling,and further improving the quality and efficiency of BIM design of railway signaling.
