面向智能城际铁路的大数据服务架构及数据交互设计

Big Data Service Architecture and Data Interchange Design forIntelligent Intercity Railway

近年来,智能城际铁路成为城际间轨道交通新的发展方向,城际铁路智能化水平得到了一定提升。建设智能化城际铁路,需围绕城际铁路全专业领域开展典型应用设计,并基于各专业丰富的数据资源,实现核心业务的深度融合,打破专业间的数据孤岛,真正实现跨制式、跨层级、跨区域的数据互联互通。在分析智能城际铁路数据服务需求的基础上,采用“平台+应用”的模式,给出智能城际铁路数据服务架构设计。通过利用“湖仓一体”的数据存储技术,设计提出城际铁路智能化的数据架构,基于智能城际铁路云脑平台,构建典型应用间的数据交互设计,形成智能城际铁路大数据服务体系,并根据典型应用的使用特点,设计应用间数据交互共享流程,为城际铁路智能化应用的建设提供数据支撑。

In recent years,the intelligent intercity railway has a new development direction for intercity railway transit,and the intelligence level of the intercity railway has been enhanced.Constructing intelligent intercity railway needs to carry out typical application design around the whole professional fields of intercity railway,realize the deep integration of core business based on the rich data resources of various professions,break the isolated data island between professions,and truly realize the cross-system,cross-level and cross-regional data interconnectivity.Based on the analysis of intelligent intercity railway data service demand,this paper adopted the mode of“platform and application”to propose the intelligent intercity railway data service architecture design.The intelligent data architecture of intercity railway was designed and proposed by the data storage technology of“Data Lakehouse”.Based on the intelligent intercity railway cloud brain platform,the data interchange design between typical applications was constructed to form the big data service system of the intelligent intercity railway.The data interchange and sharing process between applications was designed according to the usage feature points of typical applications to provide data support for the construction of intelligent intercity railway applications.
