On the morning of November 4th, Lu Xiang, deputy general manager of Jiangsu Unicom, She Caigao, chairman of Nanjing Metro Group, and other relevant leaders conducted investigation and acceptance of the 5G+ rail transit pilot project of the subway horse group vehicle base. The project successfully passed the acceptance, which marked Nanjing China Unicom and Nanjing Metro have successfully created the country's first 5G+ rail transit digital and intelligent experimental platform.

According to reports, the project achieves metro private network coverage based on the coexistence of 4G base stations and 5G base stations for scenes such as tracks, platforms, machine rooms, garages, and maintenance workshops, and upgrades the existing Internet services of the metro to 5G networks, and utilizes 5G large bandwidth characteristics Solve the problem that the original system does not have multi-channel high-definition video return.

In addition, the 5G coverage of the tunnel scene was increased, and the upgrade of the 5G private network was completed and the first domestic smart urban rail was successfully constructed and debugged. At present, Nanjing Metro has been able to realize multi-channel 4K high-definition video return and the human body through the picture without delay perception test. The on-board big data fault diagnosis system and train control system have been docked. 5G has realized the real-time return of on-board big data. After the control system is successfully connected, the control delay is as low as 4ms.

Since its establishment, the 5G+ rail transit project has been selected as a new industry project of Nanjing's "Four New" Action Plan, and has been released as the top ten application scenarios of Nanjing's new industries. The test platform has also created many firsts: the first nationwide platform that uses MEC edge computing equipment to build rail transit business; 　the nation’s first rail transit production business 5G+ verification test project that includes a signal system; 　the first test covering all subway services; 　first A test covering all subway scenarios. The test scenarios include multiple subway application scenarios such as railroad areas (tunnels, ground and elevated), stations, equipment rooms, garages, etc.

The construction of the smart rail transit project has not only greatly improved the disposal efficiency and intelligence level in the operation of Nanjing Metro, but also provided preparations for the future driverless line—Nanjing Metro Line 7.

According to the innovative achievements and later plans of the Metro Construction Company and the Nanjing Unicom Project, the "5G+Smart Rail Transit" project will use the Nanjing Metro Line 2 Maqun Vehicle Base as a platform to effectively utilize the complete urban rail transit scenes, categories, and categories of the base. The test conditions of the business will gradually achieve the overall project goals.
