Overview
China’s mid- and long-term railway network plan refreshed in 2008 shows a grand blueprint. By 2020, the total operating mileage of China’s railways will reach more than 120,000 kilometers, and a railway network of “four verticals, four horizontals and three regions” will be built. High-speed railways have shortened the distance between the urban economic circle and changed the way people travel and life patterns.
An Introduction
Huawei’s smart railway solution combines railway business and operation system, effectively integrates advanced communication, automatic control, information processing, computer, sensor and other technologies, and provides end-to-end solutions covering converged communications, railway business informatization, and auxiliary operations. Ensure the safety and efficiency of railway core business and the value-added of core assets.
The plan is as follows:
The core of Huawei’s smart railway solution:
Secure integrated communication network: Provide secure channel guarantee and communication business services for the information interconnection of railway transportation organization, passenger and freight marketing, operation and management, and realize collaborative work and information among railway businesses, assets, businesses and assets, and operating organizations shared.
Through a variety of modern sensing technologies (such as: M2M), railway assets are made perceivable, and the running status of railway assets collected in real time is transmitted to each production unit through a secure communication network, so that railway assets can be perceived, safely detected, and position.
Comprehensive platform for railway business informatization: It provides core platform support for railway daily operation informatization. On the core platform, it can be quickly customized and developed according to railway business needs to realize intelligent transportation organization, socialization of passenger and freight marketing, and modernization of operation and management. The integrated information platform is an open platform that can cooperate with a large number of enterprises on the road to create a win-win ecological chain.
Program features
Huawei’s smart railway solution has the following features:
Unified bearer network solution: Plan the bearer network architecture of the national trunk, road bureau, and passenger dedicated network in a unified manner. According to the security level of the business, E2E design service reliability and QoS guarantee from the perspective of the entire network. At the same time, it can smoothly evolve to an IP-based network and support the development of railway data services. In terms of project implementation, the unified bearer network can be implemented hierarchically and in stages based on the existing network and development needs.
National trunk bearer network solution: Using advanced OTN-ASON technology, compared with traditional WDM equipment, it improves reliability and simplifies operation and maintenance complexity.
Road office bearer network solution: unify the bearer network architecture of road office and passenger dedicated network, introduce MSTP/ASON, WDM backbone network and adjacent lines to replace light to form a protection ring, and provide redundancy against multiple failures for important services Ability to enhance the reliability and security of the business. The MSTP+-based IP bearer network smoothly supports IP data bearer based on MSTP and supports the development of railway data services.
Converged business network solutions: In addition to supporting the communication services currently in use by railways, it can smoothly expand and quickly provide new services (broadband services) to support the development of railway services.
IMS-based telephone switching network: IMS is the ultimate core network, and access has nothing to do with the network. Various access terminals can be used to carry out services according to railway needs. Services are separated from the network, and new services can be deployed quickly according to the needs of railway development without changing the network.
Special mobile communication (GSM-R): Provides integrated special mobile communication integration solutions based on softswitching core network, base station, repeater/leaky cable, terminal, etc., to realize wireless trunking dispatching business and train control data between vehicle and ground , And support the evolution to LTE.
Car-ground wireless broadband communication: It is a secure communication channel between high-speed train cars and ground. It can be a GSM-R backup network to further improve network reliability. At the same time, it can carry different levels of services, and the services are isolated from each other. The business can be the internal railway transportation organization business (such as: safety monitoring of train equipment operation status, video surveillance); it can be the internal railway operation and management business to realize train informatization; it can also be the public service business such as passengers (such as: PIS) , Provide broadband communication channels for passengers on high-speed trains, and provide passengers with public services and broadband services of the same quality as those on the ground.
Comprehensive support network solutions: Provide products and solutions covering signaling networks, synchronized clocks, and integrated operation and maintenance. The integrated operation and maintenance system can support the integrated access of equipment from multiple disciplines and manufacturers. The communication network is managed as a single network, showing the topology of the entire network, centralized management of the resources of the entire network, and equipment failures can be quickly located through cross-professional correlation analysis. The root cause is to improve the efficiency of operation and maintenance and reduce the difficulty of operation and maintenance.
Integrated service solutions: such as green computer rooms, wireless bridges and tunnels/indoor coverage, integrated sites, etc. Some project delivery work is done in advance. Once the project conditions are met, the installation and implementation can be quickly completed on-site and delivered to operation. Combining the network planning, integrated delivery, and management service experience capabilities that Huawei has accumulated in the telecommunications field, Huawei can extensively cooperate with on-road companies to assist the operation of railway communication networks, reduce operating costs, and improve operating quality.
The application and value of the solution
The increasingly complex railway network and the rapid growth of railway assets affect the operational efficiency and operating costs of daily railway operations. Informatization of railway business is an inevitable trend. Huawei provides customized information solutions based on specific railway business requirements and application scenarios to promote the process and automation of daily railway operations.
Core platform: Provides public platforms and basic components for railway informatization, including security platforms, data centers, and basic components such as storage and servers. The security platform implements hierarchical security assurance from network, application, and desktop access. The data center realizes the sharing of data across the road to support production operations and business decision-making.
Safety management: According to railway safety requirements, provide railway safety management solutions, including railway asset safety inspection and emergency rescue command.
Project management: Provide the project management (tunnel management, emergency rescue) program in front of the station to ensure the implementation quality of the project in front of the station and rapid emergency response.
Provide CTCS-3, compatible with CTCS-2 signal system, independent research and development of the core platform, to break the monopoly of core technology by overseas manufacturers. Provide a comprehensive video monitoring integration solution to realize the visualized train driving safety monitoring.
Provide the ultimate switching network based on IMS, and provide integrated office solutions for railways, such as integrated conferences, unified communications and other modern office methods to improve office efficiency.
Use modern sensing (such as: M2M), communications, computers, e-commerce and other technologies to create a modern logistics management system, intelligently dispatch freight, and track and manage items.
The call center integration program integrates ticketing and customer service, and provides multi-channel ticket management methods (telephone booking, online booking) and service quality management to improve passenger satisfaction.
