The subway, like the pulse of the blood vessels of the city, injects life and vitality into the city. When each train roars through the ground or air of the city, the whole city seems to be instantly injected into the soul and burst into new hope. By the end of 2022, 51 cities across the country have built urban rail transit systems, with a total passenger volume of 19.4 billion passengers in the whole year, providing a solid boost to the development of cities at sunrise and lunar setting.

As the birthplace of China's first subway, Beijing is currently the city with the largest daily passenger volume of rail transit. Behind this, Beijing Urban Construction Design and Development Group Co., Ltd. (hereinafter referred to as "urban design") can be described as an unsung hero of silent dedication. In the early days of the founding of the people's Republic of China, in order to complete the survey and design service of Beijing Metro Line 1, China's first subway, the Beijing Urban Construction Design and Research Institute was officially established, which is one of the earliest survey and design units in China and the predecessor of today's urban construction and design.

Despite the meritorious deeds and achievements in the past decades, with the rapid development of cloud computing, big data, artificial intelligence and other emerging information technology, digital transformation has become a necessary option in front of urban construction design. However, what kind of road of digital transformation should we take? With digital cloud fusion as the core methodology of enterprise digital transformation, Digital China assisted urban construction design to successfully build big data Center of urban construction UCD industry, and helped urban construction design draw the second growth curve of enterprise development in the era of digital civilization by realizing the interconnection of data assets in the cloud, opening up data channels and breaking down data barriers.

Cloud on the urban rail, build the underlying infrastructure of the intelligent urban rail

In March 2020, China Urban Rail Transit Association issued the outline of China Urban Rail Transit Smart Urban Rail Development, which marked the full implementation of urban rail enterprise smart urban rail planning. For urban construction design, at a time when the power of digitization can not be ignored, the design of urban rail transit system must be oriented to the future. From the point of view of urban construction design, every subway station scattered in the city is equal to a data center, and there have been problems such as isolated information and complicated processes for a long time. Therefore, the core of the intelligence of urban rail transit is to connect the independent data centers from the point to the network, and the urban rail cloud platform has become the core fulcrum to fully connect the data and release the value of data assets.

■ Urban Rail Cloud is essentially a private cloud

Shangyun is the first step in the digital transformation of Qianhang Baiye. However, because the urban rail cloud operation and maintenance management cannot be open to the public network, otherwise it will have a great risk of intrusion, so the urban rail cloud is essentially a private cloud, which requires that the urban rail cloud platform can ensure that the basic and high-level functions are deployed locally, instead of opening the original safe and closed operation and maintenance network to the public network to realize the operation and maintenance of the urban rail internal private network by external manufacturers.

■ ensures flexible expansion of infrastructure resources

In the face of the construction needs of urban construction design, Digital China starts with the virtualization of local infrastructure hardware facilities such as servers and supporting switches, upward providing virtual resources such as computing, network and storage, and downwards meeting the needs of local proprietary, security and compliance features, so as to ensure that users can apply for IaaS resources as needed. Furthermore, the required application systems, supporting development, operation and maintenance tools, and data products and services can be dynamically deployed. At the same time, in order to meet the expansion needs of urban rail cloud platform in the process of urban development, Digital China took into account the smooth expansion function in the process of building urban rail cloud platform, so as to meet the needs of urban rail cloud node scale expansion and software function upgradeability in urban dynamic changes.

Another Leap from Agile to DevOps in ■

In the process of enterprise cloud development, cloud development has become the first choice for enterprises to build digital business, and cloud native technologies represented by containers, service grid, micro-services, immutable infrastructure and declarative API have been widely adopted. Therefore, in order to help urban construction design finally achieve unified cloud management, unified cloud services, unified data services, unified cloud operations, unified cloud certification, unified cloud operation and maintenance, and unified cloud security, Digital China specially designed the cloud native DevOps system based on its own cloud native platform DCCNP, which helps the urban rail cloud platform of urban construction design to achieve automated assembly line project delivery mechanism, and deploy Kubernetes container clusters that support multi-cluster management. Through the product lifecycle guarantee from project requirements management, continuous integration, continuous deployment, continuous testing and continuous monitoring, it further improves the agile control of urban construction design for the whole process of the project.

Data assets, the core of smart urban rail enabling business innovation

With the private cloud platform as the infrastructure supply layer of big data Center in the urban rail industry, the goal of urban construction design is to build a comprehensive big data center covering engineering design, construction and operation data of the urban rail transit industry, and finally shape the core competitiveness of digital rail transit and provide customers with digital, intelligent and professional services. To take a simple small example, even if the subway station door is closed, which occurs countless times a day, digital cloud fusion can also determine the alarm interval and alarm frequency through the big data analysis of each subway station, thus effectively reducing operating costs. let the subway station operation burst out new kinetic energy.

In order to avoid the separation of the cloud platform from the big data platform, Digital China assists in building an industry big data center with unified data access, unified data standards and unified data services on the basis of a private cloud environment that integrates computing, network, storage and other resources. achieve data interconnection, through big data mining, analysis technology, help urban rail transit operation and management capabilities and improve the level of public information services To assist the scientific decision-making of urban rail transit operation planning.

■ Construction Industry data Model

There is a large amount of heterogeneous data in the urban rail industry. The first task of Digital China is to break through data channels, break down data barriers, achieve data interconnection and form a unified underlying data. Therefore, Digital China collects, integrates, governs and models the data of different data systems by establishing an urban construction design sharing big data exchange system, collecting input department data, third-party business data and Internet data, and comprehensively analyzes the business definition and rules of urban construction design, forming data assets that are convenient for data location and use. Then use statistical model, deep learning, machine learning and other technologies for energy consumption, equipment failure statistics and analysis, and finally provide data decision support for subway operation. In addition, according to the different needs of different parts of the data, Digital China also specially set different data management permissions in the system to facilitate the reasonable sharing of data.

■ Construction data Standard Specification system

As there are a variety of technical standards and software platforms in the rail transit industry, and the data requirements of each subsystem are also different, it is difficult to standardize the data organization structure and transmission form. In order to improve the fluency of data flow, the depth of information sharing and the efficiency of the development and utilization of information resources, the data governance team of Digital China analyzed the characteristics of the data use standards of urban construction design, help urban construction design build a data standard specification system covering basic standards and applied standards, achieve the consistency of data definition, and effectively reduce data barriers between various departments.

■ builds data Lifecycle Governance system

Digital China not only assists urban construction design in compiling metadata and data standards and information resource catalogue, but also continuously monitors data quality fluctuations and provides rectification plans through the data quality management platform, and constructs a full life cycle management system of data. it has realized the maintenance monitoring of major equipment and platform intelligent management and control, and will further integrate the business data flow to complete the integration of production and business. In terms of security and privacy, Digital China effectively protects project data and customer privacy by formulating appropriate security policies and measures.

Han Dezhi, director of the digital center of Beijing Urban Construction Design and Development Group, said: "Digital China assists in the big data center of urban construction design and construction, which is an industry with unified data access, unified data standards and unified data services, and has achieved data interconnection. Through the data cloud fusion capability of cloud computing and data platform, the urban construction design realizes the overall evaluation and detailed fault prediction of equipment maintenance, avoids the potential production business risks, and optimizes the cost of equipment maintenance. build a safe, convenient, efficient, green and economical new generation of Chinese intelligent urban rail transit. "

At present, the big data Center of the urban construction industry assisted by Digital China has landed on the rail transit system of Qingdao, Kunming and other cities, and will gradually land on more fields such as municipal engineering, urban planning, integrated transportation hub and so on. At the moment when digital transformation has become a compulsory course for enterprises, digital strategy is enterprise strategy. Adhering to the original intention of Digital China, Digital China, centering on the strategic framework of digital cloud integration, is committed to becoming a leading partner in digital transformation, helping enterprise customers of thousands of industries to build core competitiveness for the future.
