摘　　要：我国今后新建铁路将逐渐减少,既有线改造工程将不断增加,亟需加快信号系统接口标准化研究工作。欧洲铁路信号联盟(EULYNX,European Imitative to Linking Interlocking Systems)致力于信号系统接口标准的制定,为信号系统升级改造奠定有利的数字化基础。文章介绍EULYNX信号系统数据模型,简述信号系统的构成和数据准备流程,详细说明数据需求定义过程、UML建模过程以及EULYNX数据模型的应用流程。与非结构化方法相比,形式化的EULYNX数据模型便于用户在网页上浏览,也可使用软件工具灵活地提取和处理其中的数据,还支持由工具直接生成高级语言代码。此外,EULYNX数据模型具有可视化、规范化的特点,有利于信号系统升级改造工程的相关方基于同一数据模型开展合作,保证需求与实现的一致性,便于实现信号系统全生命周期内无缝信息交换。EULYNX建立的信号系统接口标准化方法,可为今后国内既有线信号系统接口标准化研究工作提供重要参考。Fron now on, newly-built railway lines will gradually decrease while the upgrade and reconstruction projects of the existing railway will increase constantly in China. So, it is urgent to speed up the standardization research on the interfaces of signal systems. EULYNX(European Imitative to Linking Interlocking Systems) is committed to formulating the standard of the interfaces of signal systems, thus laying a favorable digital foundation for the upgrade and renovation of signal systems in European railways. This paper introduces the EULYNX signaling data model and briefly describes the composition of signal systems in the model and its data preparation process, and gives detailed description on the data requirement definition process, the UML modeling process as well as the application flow of this data model. Compared with unstructured approaches, the EULYNX signaling data model is formal and convenient for users to browse the data model on the web page, enables flexibly extract and handle the data in the model by using software tools, and supports the direct generation of high-level language code via tools. In addition, the EULYNX signaling data model has the characteristics of visualization and standardization, which is conducive to the cooperation between relevant parties of a upgrade or reconstruction project of the signal system based on the same data model, thus ensuring the consistency of requirements and implementation, and facilitating the seamless data exchange in the whole life cycle of the signal system. The signaling interface standardization method established by EULYNX can provide an important reference for the future research of signal system interface standardization of existing railway lines in China.tem interface standardization of existing railway lines in China.
