本课题通过调研国内外城轨领域云平台、数据平台、网络安全的研究现状。针对目前国外无参考案例，国内云平台、数据平台、网络安全建设融合协同性不足的问题。分析了云架构下数据平台的实施需求，重点研究了云数据库、数据平台的技术栈比选、云平台与数据平台纳管等，分析了城轨云平台网络安全总体需求，深化研究了云内统保和系统自保以及云平台和数据平台与网络安全资源池的协同，提出了融合云平台、数据平台、网络安全、数据资源和系统运维统一协同化的管理中心。研究表明：做好数据平台总体规划和选型和利用软件定义安全技术，可实现云平台、数据平台、网络安全的融合协同，可为城市轨道交通数字化转型及智慧化升级提供参考和借鉴。

This paper investigates the research status of cloud platform, data platform and network security in the field of urban rail at home and abroad. At present, there is no reference case abroad, and the integration and cooperation of domestic cloud platform, data platform and network security construction is insufficient. Data platform of the implementation of the requirements under the cloud architecture are analyzed, the research is mainly focused on the cloud technologies stack of database, data platform, cloud platform and data platform convergence, etc., analyzes the overall cloud city rail network security requirements, deepen the cloud was studied in the same system and self-preservation and cloud platform and data platform and network security resource pool together, A unified and collaborative management center integrating cloud platform, data platform, network security, data resources and system operation and maintenance is proposed. The research shows that the overall planning and selection of data platform and the use of software defined security technology can achieve the integration and collaboration of cloud platform, data platform and network security, which can provide reference and reference for the digital transformation and intelligent upgrading of urban rail transit.
