BIM技术在铁路信号工程设计中的应用研究

铁路信号工程具有多子系统、设备离散布置、系统网络连接、信号集中控制、表达抽象及逻辑制约关系复杂等特点。围绕基于BIM技术实现多源异构系统之间的信息交换这一核心目的,分析当前铁路信号工程领域BIM相关技术标准及建设现状,从铁路信号工程设计的信息交换维度出发,探讨信号专业参与协同平台研发的必要性和需要解决的实际问题,提出信息化辅助设计方案,并通过二维可视化辅助设计软件进行验证。研究表明:对于铁路信号工程设计的BIM应用,不能照搬现有的技术,需要结合本专业的设计特点,以信息交换为核心进行相应的辅助设计软件开发,提升铁路信号工程设计的信息化水平和设计效率。

Research on the Application of BIM in Designing of the Railway Signaling Engineering

Railway signaling engineering has the characters of multiple subsystems,discretely deployed equipment,system connection by network,centralized control of signal,abstract design expression and complicated constraint relationship.Based on the core purpose of realizing information exchange between multi-source heterogeneous systems with BIM technology,the current construction status and related technical standards of BIM in the railway signaling field have been analyzed,and the necessity of signaling specialty participating in the collaborative platform has been proposed by studying from the information exchange dimension of the railway signaling design.The information-based auxiliary design program has been proposed and verified by two-dimensional visual aided design software.The study shows that the BIM concept should be introduced into railway signal engineering in consideration of its inherent design characteristics rather than just blindly cloning from the existed application,and correspondingly,auxiliary design software with information exchange as its core function should be developed in order to improve the informatization and efficiency level of the railway signaling engineering design.
