铁路信号一体化设计平台数据库设计

摘要

开发基于数据库的铁路信号一体化设计平台是解决当前各个辅助设计软件存在诸多问题的方法之一.通过分析铁路信号工程图纸反映的信息特点,提出了室内外信号工程基础数据库的设计原则及数据流模型,并采用定义外键等数据库技术建立铁路信号工程关系型数据库.平台以该数据库设计方案为基础构建,已在铁路信号工程设计中实际应用.%Developing the railway signal integrated design platform based on database is one of the methods to solve problems in current aided design software. Through analyzing the information characteristics of railway signal engineering drawings, this article proposed the design principle and data flow model for the basic database of indoor and outdoor signal engineering, set up the relational database of railway signal engineering by using database technology such as defining a foreign key, etc. The platform was established based on the database design scheme, and applied in the railway signal engineering design.
