轨道交通数据中心实时单向数据摆渡设计与实现

针对轨道交通数据中心业务的单向安全隔离环境,以保障生产控制数据的实时性与安全性为目标,提出了基于企业服务总线级联、消息队列数据推送和结合业务应用的通信模式采用过滤命令回传的数据摆渡方式,以及实现生产控制系统实时数据传输的方法,并对其进行了测试。测试结果表明,该方法可应用于轨道交通领域生产网域和管理网域的数据隔离,以确保生产网域数据的安全性,并保障管理网域可获得必要的数据。

Research of Real-time Data Signal-direction Ferry in the Data Centre of Shanghai Metro

Regarding the one-way safety isolation environment at DC of Shanghai metro,a set of data ferrying methods is introduced,it incorporates the cascade connection of enterprise service bus (ESB),raw data push of message queue,and data backhaul through filter based on communication modes.The purpose of the data ferrying method is to execute the real-time data transmission in production domain,and test the data transmission.The result shows that this method could keep the security of these production control data,in order to ensure the necessary date being obtained by management domain.
