摘要:
目的：为了解决城市轨道交通各条线路停车场和车辆段(以下简称“场段”)的共用问题，需要设计多场段智能管控系统数据云平台，并对该平台的应用效果进行研究。方法：基于城市轨道交通场段的网络建设需求，综合星型网络、环形网络及网状网络结构的特点，以及车辆基地的网络特点，结合布设成本，确定云平台网络架构采用星型网络结构。以北京地铁12号线和北京地铁3号线共用的1座车辆段和1座停车场为研究对象，对云平台进行了优化设计和分析，并从云服务安全框架和安全支撑(软硬件)系统等方面对该平台的云服务进行了安全设计。结果及结论：多场段智能管控系统数据云平台的使用，优化了服务器数量、系统发热量及成本等资源。采用星型网络组网方式，降低了组网投资成本，提高了数据传输速率。云平台采用超融合技术处理方式，提高了应用层系统的稳定性。将原来众多仅能通过通信协议对接的多种形式的接口数据以统一接口发送至云平台，建立了场段智能检修建设标准、统一的应用服务和数据格式，实现了运营公司的标准化管理。

Objective: To address the challenges of shared usage among parking lots and vehicle depots (hereinafter abridged as ′segment′) of various urban rail transit lines, the need arises to design a MIMSDCP (multisegment intelligent managementcontrol system data cloud platform) and to investigate its application effects. Method: Based on the network requirements of urban rail transit segments, considering the characteristics of star networks, ring networks, mesh networks, as well as the network features of vehicle bases and the cost of deployment, the network architecture of the cloud platform is determined to adopt a star network structure. Taking a shared vehicle depot and parking lot between Beijing Subway Line 12 and Line 3 as a study case, an optimized design and analysis of the cloud platform is conducted. The safety design of the platform cloud service is carried out from aspects including cloud service security framework and security support (both software and hardware) systems. Result & Conclusion: The utilization of the MIMSDCP optimizes resources such as server count, system heat generation, and costs. The adoption of a star network topology reduces network investment costs and enhances data transmission speed. Employing hyperconvergence technology in the cloud platform enhances the stability of the application layer system. The integration of numerous interface data, that previously could only be connected through communication protocols is sent to a unified interface for transmission to the cloud platform，a standardized management for segment intelligent maintenance construction criteria, unified application services and data formats is established, realizing operation company standardization.
