2023 Beijing-Qingdao International Urban Rail Transit Exhibition
With the theme of "Intelligent Urban Rail Transit, Green Development", the 2023 Beijing-Qingdao International Urban Rail Transit Exhibition and Summit Forum will be held in Qingdao from April 27th to 29th. The program was unveiled and received widespread attention and high recognition from users and partners.
The Beijing-Qingdao Rail Exhibition is sponsored by the China Urban Rail Transit Association, specially invited by Beijing Investment Corporation and Qingdao Metro to co-organize it. China Railway Qingdao World Expo City has an exhibition space of more than 60,000 square meters, setting a record high in the scale of the exhibition; "13+N" vehicles It is the most influential brand exhibition in the field of urban rail transit in China, with a multi-standard real vehicle display and a record-setting panoramic display of the country's heritage in equipment power.
At the scene, in response to the upgrade and transformation problems faced by the urban rail transit system, the smart rail transit solution of Renda Jincang that meets the needs of dual-network operation, high system availability, massive self-tuning, and non-perceptual migration has attracted much attention.
Renda Jincang can not only provide standardized solutions such as one master and multiple backup clusters, but also supports in-depth customized development of specific scenarios, which can greatly improve the convenience and ease of use experience of operation and maintenance personnel, realize seamless cutover, complete data migration without any sense, and ensure The stability of the business system and the continuity of application services have been highly recognized by users and partners.

Smart rail transit
Pioneer of Chinese-style modernization
★
As the mode of transportation with the largest passenger capacity and the fastest transportation speed in the modern transportation system, urban rail transit is not only the focus of investment in public transportation construction in various provinces and cities across the country, but also an important pillar of modern urban economic development.
With the deep integration of new technologies such as 5G, big data, and artificial intelligence with transportation, smart city rail transit has emerged as an emerging business format. The realization of automatic train control, intelligent passenger service, intelligent operation management, and intelligent maintenance guarantee, while ensuring the efficient operation of the rail transit system, enables the people to better experience the achievements of intelligent service and intelligent management, and become a smart It is an important part of urban construction, and it is also a key step for our country to build a transportation power with "people's satisfaction, strong security, and world-leading".

In recent years, a number of important policies have been implemented such as "Opinions on Accelerating the Construction of a Powerful Transportation Country Driven by Scientific and Technological Innovation", "The Outline of the Medium and Long-term Development Plan for Scientific and Technological Innovation in the Transportation Field (2021-2035)" and "The 14th Five-Year Plan for Scientific and Technological Innovation in the Transportation Field" Zhongdu pointed out the determination of the implementation of traffic innovation.
The independent controllability of key core technologies is not only related to the daily travel of the masses, but also related to national security and development. Based on many years of practical experience in the industry, Renda Jincang vigorously promotes independent innovation on the basis of fully understanding the business model, network structure and security status of the automatic train control system (ATS), automatic fare collection system (AFC), subway company IT system, etc. The deep integration of technology and smart rail transit, focusing on comprehensively improving the development level of smart transportation, has created an urban rail transit database solution for defense in depth, and accelerated the development of new transportation infrastructure.

Flexible and Compatible, Autonomous Switching
Jincang database implements client application based on domain name and dual network segment IP address configuration, high availability components support dual network card fast switching, realizes decoupling of IT environment, and meets high availability requirements of synchronous network.
Real-time synchronization, seamless migration
During the migration process, new data changes (addition, deletion, and modification) in the original production area can be captured, and a local cache strategy is provided to quickly catch up with the data and achieve data synchronization at both ends, effectively ensuring data consistency.
Automatic recovery, no fear of failure
The database adopts a dual-center deployment, one master and three backup cluster schemes. When the database host (non-network reason) fails, the cluster automatically switches to the standby node in sequence; resilience.
Automatic early warning, intelligent operation and maintenance
Jincang Database provides monitoring services including host monitoring, single-instance monitoring, cluster monitoring, and multi-dimensional performance indicator monitoring. By configuring different monitoring indicator control and early warning strategies, it conducts regular inspections and automatically alerts when abnormal monitoring indicators are found.
At present, Renda Jincang has served more than a dozen subway lines including Tianjin Metro, Shenzhen Metro, and Shijiazhuang Metro, which are distributed in many cities across the country.
In the future, Renda Jincang will continue to build the industry's innovation ecology, strengthen independent innovation, form a number of internationally leading and widely used smart transportation technologies, products and services, and escort the construction of a smart city and a transportation power.
