Recently, it was learned from the 2021 Beijing International Urban Rail Transit Summit Forum·Sub-forum One-"Smart Urban Rail Innovation Forum" that 4 urban rail transit scientific and technological achievements transformation projects were officially signed for strategic cooperation. The signing ceremony of the transformation strategy for urban rail transit scientific and technological achievements is not only a concentrated achievement display of the "China Urban Rail Transit Scientific and Technological Progress Award", but also a concrete manifestation of the implementation of the Law of the People's Republic of China on Promoting the Transformation of Scientific and Technological Achievements and the promotion of smart urban rail construction.

The first contracted project is "Research and application of large-bandwidth real-time backhaul for rail transit vehicle-ground wireless communication based on Wi-Fi 6 technology".

Shenzhen Metro and Huawei have carried out research on large-bandwidth real-time backhaul of wireless communications for rail transit vehicles. Based on in-depth analysis of subway tunnel signal models, they have developed the Midamble high-speed mobile enhancement algorithm with international core patents and five exclusive patents. Re-switching optimization algorithm, and incorporated into the IEEE standard patent system, can achieve a maximum of 1Gbps at 120km/h speed, an ultra-high communication bandwidth of 900Mbps at 160km/h speed, and zero packet loss channel switching under high-speed operation, providing stability for train operation Reliable real-time communication lines have been applied to Shenzhen Metro Line 20, becoming China's first autonomous driving urban rail line using Wi-Fi6 technology. Shenzhen Metro and Huawei Technologies Co., Ltd. will continue to explore the in-depth cooperation of ultra-high-speed and low-latency Wi-Fi6 technology that can bring safety, experience, and efficiency improvements to urban rail communications, and fully lead the era of autonomous driving in smart urban rail.

The second contracted project is "Research and Application of Multi-standard Compatible Signal System Facing Line Network Convergence".

Facing the need for signal systems in urban rail transit network operation, Changchun Rail Transit Group and the Shanghai Metro Urban Rail Transit Technology Co., Ltd. carried out research on signal systems for line network integration, forming a signal system that is compatible with multiple signal systems Results. This achievement has been applied to Changchun City Rail Transit Line 3, which realizes that under the condition that the track circuit-based signal control system is used on the existing line, the extension line adopts the CBTC system, and a set of on-board signal equipment is compatible with the track circuit-based signal control system. The ground signal system of the CBTC system and the ground signal system have achieved full-line operation, and has now entered the stage of no-load trial operation. This achievement can realize the cross-standard operation between different standard signal systems, keep up with the technological development of the industry, and have the "three networks integration" proposed in the "Smart Urban Rail Development Outline" to achieve the "triple network integration of urban rail, urban express rail, and intercity rail At the same time, the efficient use of existing resources in construction and operation provides a brand-new technical application idea for the transformation of existing lines. In the future, this achievement will be promoted and applied in Changchun Rail Transit Line 4.

The third contracted project is "based on 5G virtual private network and 5G industry private network technology pre-research and rail transit communication signal integrated bearer application."

BYD Communication and Signal Co., Ltd. and Beijing Jiaotong University have carried out research on the integrated bearer application of 5G virtual private network and 5G industry private network in rail transit communication signals to improve rail transit operation efficiency, reduce operation and maintenance construction costs, shorten construction periods, and improve network capabilities Improve the utilization of network resources; verify the application of 5G private networks in rail transit spectrum resources, key technologies and scenarios, and promote the development of 5G in the rail transit industry. While keeping up with the technological development of the industry, the existing resources for construction and operation are efficiently used to provide brand-new technical application ideas for the transformation of existing lines, and to promote and apply them in rail transit.

The fourth contracted project is "Huhhot Urban Rail's "Using Industry-University-Research" Joint Innovation Strategy".

Hohhot urban rail proactively follows the industry and cloud computing development trends, and has created the Hohhot "urban rail cloud platform". After more than two years of operation practice, the system is safe and stable, and business needs respond quickly. The "Qingcheng Metro App" and WeChat have been launched successively. Over a dozen convenient payment services including Alipay, UnionPay, Beijing-Mongolia Interoperability, Face Recognition, and Interoperability of "Four Provinces (Regions) and Five Cities" in Northeast China. This project won the first prize of China Urban Rail Transit Association's 2020 Science and Technology Progress Award.

According to reports, this joint innovation cooperation will take the Hohhot Urban Rail Cloud Platform as the supporting base and the core business of urban rail construction and operation as the guide. Through the research and application of emerging information technology, the Hohhot Urban Rail Transit Construction Management Co., Ltd. Beijing Jiaotong University, China Railway Design Group Co., Ltd., Beijing Hollysys System Engineering Co., Ltd., Traffic Control Technology Co., Ltd., Huawei Technologies Co., Ltd., Founder International Software (Beijing) Co., Ltd., Casco Signal Co., Ltd., Beijing Jing Nine units including YEDA Digital Technology Co., Ltd. and Beijing Guanhua Tianshi Digital Technology Co., Ltd. have fully utilized the advantages of each unit to build common standards, shared data, shared services, changed combinations, and based on new access models and new businesses. The model of Hohhot's new-type urban rail transit "three-in-one, one-change and two-new" application system realizes the comprehensive innovation of technology, business, and business models, and implements the construction of smart urban rail industry.
