Managing Increasing Scale and Passenger Volume

With significantly increasing scale and passenger volume, there is demand for urban rail lines to be integrated into multi-line networks that require more efficient, smart operations. Such growth poses new challenges to ICT systems.

Automatic train operation requires extensive, reliable information systems and service linkage. Yet urban rail lines operate independently and lack consistent service architecture, technical platforms, and data. Scattered IT devices are unable to support the unified operation of multiple lines.

Given this existing ICT architecture, it is difficult to share urban rail construction and operations experience or to innovate services. Yet a smart cloud platform can offer secure infrastructure that accelerates the transition from single-line to multi-line operations

Cloud Platform and Virtualized Servers

An urban rail cloud platform centrally carries ISCS, AFC, PIS, ACS, CCTV, and other application systems. The platform integrates resources, and standardizes architecture and data. This facilitates resource sharing, on-demand allocation, and flexible scaling, supported by unified operations, collaborative services, standardized and normalized services and data, as well as unified and platform-based resources and architecture. The platform help customers transform from single-line to multi-line operations, and lays a solid foundation for closer service linkage and the deployment of big data analytics.

Intra-city Remote Disaster Recovery for Mission-Critical Services

Hierarchical intra-city remote disaster recovery architecture provides different services with specific reliability mechanisms, such as an active-active for mission-critical services, eliminating service interruption and Virtual Machine (VM) cluster backup, with other mechanisms for non-critical services.

VM live migration ensures service continuity even with faulty physical devices. FusionSphere virtualizes computing, network, and storage resources into virtual resource pools and supports cluster deployment. Large-bandwidth Dense Wave-length Division Multiplexing (DWDM) networks are used for transmission. This scheme achieves dual-activation for mission-critical urban rail services between the active and standby data centers and ensures 24/7 service availability, with Disaster Recovery (DR) capabilities significantly improved.

Network Border Isolation and Hierarchical Security Protection

Passenger services, management information, and safe operations networks are isolated in the urban rail cloud information system. An information security protection plan, in compliance with China’s national Level 3 information security standards, is implemented for the operations network. An overall security framework is also designed for the ICT-based cloud platform to guarantee effective security protection for the cloud platform, Operations and Maintenance (O&M), and infrastructure layers.

Modular Data Centers — Green, Energy Efficient, Reliable, and Quick to Deploy

Energy-efficient modular data centers integrate power supply and distribution, cooling, security protection, power, and environment monitoring systems, as well as cabinets. The modular design enables rapid deployment and meets energy saving and reliability requirements. Digital components supporting intelligent management, the monitoring of real-time running status, and automatic fault location increase O&M efficiency. Multiple energy-saving measures improve Power Usage Effectiveness (PUE) to 1.45.
