Overview of H3C Smart Urban Rail Solution

Construction background

Transit systems for medium and large cities are increasingly being densified, moving from a "station-line" mode to a "station-line-network" mode. The huge construction scale and investment amount of rail transit requires the rail transit industry to follow the development direction of world rail transit technology and informationization, and to promote technological innovation and informationization in order to maintain engineering quality, traffic safety, and service quality. The integration of resources and data has resulted in automation and intelligence becoming critical components of urban rail operations, ushering in a new era of networked operations for the sector. H3C, a subsidiary of Unigroup, provides full-stack solutions with technological innovation that fit the user scenarios for urban rail industry.

Overview

Based on the intelligent digital platform consisting of digital infrastructure, business capability platform, active security and unified O&M, H3C Digital Brain Program carries out innovation in the application field of intelligence with ecological partners to enable customers the core capabilities of intelligent connection of everything, dynamic convergence, intelligent analysis and intelligent decision-making in enterprise development, and successfully fulfill digital transformation.

Based on the understanding and practice in the urban rail industry, H3C builds a digital brain of intelligent urban rail composed of H3C intelligent digital platform (4 component modules), equipped with N ecological applications of partners, referred to as "4+N".

In the digital brain "4+N" model, "4" mainly refers to the H3C intelligent digital platform, which is the base of digital solutions and support for smart applications; "N" stands for the smart applications for different industries, which are also the core value of H3C ecological partners. Along with cooperating with industrial smart applications and ecology, H3C also collaborates with ecological partners with technology innovation in the components of the "4" platforms.


Generally, the H3C digital urban rail cloud platform is designed based on business needs. Based on the business characteristics of the urban rail information system, the system adopts the design method of cloud computing resource pool to achieve loose coupling between IT infrastructure modules and service modules, as well as horizontal expansion of modularization of resource pools. Cloud management platforms facilitate rapid delivery and unified management of resources, as well as rapid service launch, integrated operation, and centralized O&M.

H3C Urban Rail Cloud adopts mature and advanced technology, software and equipment and coincides with the international development trend. The design process followed international norms and standards, drew on the architecture of mature Internet distributed systems at home and abroad, and tapped into the latest technological achievements in the industry, and upgraded our processes on a regular basis to ensure that the platform and application capabilities keep up with the trend. According to the comments from China Association of Metros, we will build the urban rail cloud solution in line with the "13531" architecture.

Urban Rail Line Network Cloud for Taiyuan Metro Line 2

According to Notice on the Research of Advanced Technology Solutions (Fully Automatic Operation System and Urban Rail Cloud) for the Phase I Project of Metro Line 2 (BGDF [2018] No. 12) issued by Taiyuan Rail Transit Group Co., Ltd., Taiyuan Metro is focusing on building urban rail network cloud to carry relevant service systems.

With the full-stack solution of urban rail cloud, H3C provides Taiyuan Metro with cloud platform, virtualization, computing, storage, SDN network, security and other products to guarantee the operation and production, enterprise management services and external services to the cloud, and help Taiyuan Rail complete information transformation.

Line-Network Operation Command Center of H3C Smart Urban Rail Solution

Relying on the communication, signal, AFC, ISCS, FAS, BAS, PSCADA, PIS and other services of the line control center of the rail transit network, combined with the needs of network operation management and decision analysis, the operation command center collects, stores, analyzes and explores the data of traffic, equipment, dispatching command, emergencies, passenger flow, AFC and other data of the entire rail transit network to build the line network operation command center. Functions:

As the urban rail transit enters the network operation, it imposes high demands on the data collection and resource integration of the line network command center as well as the response speed under emergencies. Under the traditional IT architecture, resources are relatively scattered, and computing and storage resources could be wasted at times. The overall resources cannot be fully mobilized in case of emergencies. With extensive experience in IT infrastructure management and operation support, specialized cloud computing technology and service practice, H3C can provide full-stack IaaS, PaaS and SaaS capabilities for line network command center construction, integrate advanced AI, big data, container and other technologies, make scenario-based customization around the urban rail transit operation index system, and perform analysis and BI display for passenger flow situation, operation index, key operation events, service situation, equipment failure situation, ticketing situation, historical operation data, personnel situation, energy consumption situation, etc.

H3C Smart Urban Rail Solution Data Platform

Overview

While urban rail transit brings many benefits to cities, it also brings great challenges to the construction and operation departments of urban rail transit around the strategic goal of building a safe, reliable, efficient, intensive and networked urban rail transit for sustainable development.

The entire life cycle of subway operations generates massive amounts of data all the time, and the establishment of a cloud platform means that the data has a "home". To make the most of data, based on the existing cloud platform, we further collect the relevant data from multiple professional systems to achieve real-time monitoring and intelligent analysis of data.

H3C data platform is based on H3C DataEngine to create an integrated AI solution for the rail transit industry:

● Build a broad data platform and data sharing platform for the urban rail industry to improve the efficiency and quality of customer data asset management;

● Use data mining, knowledge graph and other technologies, correlation analysis to achieve local applications such as fault warning, passenger flow analysis, intelligent scheduling, etc., to make operations safer;

● Network people, sensing, and intelligence, and launch comprehensive applications covering construction, operation, maintenance, and services to reduce operation and maintenance costs.
