Wuhan Metro Line 1 is the first rail transit line in Hubei Province, China, which was put into operation on July 28, 2004. As the first CBTC metro line in China, Wuhan Metro Line 1 transformed the traditional metro signaling control mode in China, and provided a valuable reference for the subsequent digital upgrade of Chinese metro signaling systems.
As the first signalling system overhaul project of Wuhan Metro, Wuhan Line 1 overhaul involves the following control areas: four equipment centralized stations, two border centralized stations, as well as the upgrading of central VCC1 and VCC2. The main hardware upgrades include: the central VCC1 and VCC2 equipment (upgraded from the 2nd generation to the 3rd generation), the trackside VCC1 STC equipment (upgraded from the 2nd generation to the 3rd generation), and the trackside VCC1 axle counting equipment (upgraded from ZP30C to ZP30H).
As a metro line passing through multiple bustling business districts in Wuhan, Metro Line 1 transports a large number of passengers every day. With the cooperation of Wuhan Metro, Thales SEC Transport (thalessec.com.cn) formulated the implementation strategy of "Partial before Overall, and ATC before Backup" through reasonable planning and in-depth research, overcame multiple difficulties in the implementation, and successfully completed the overhaul project without any impact on daily operation. At the same time, Thales SEC Transport has greatly improved the system performance by applying techniques such as serial optical communication conversion and redundancy self-test optimization.
About Thales SEC Transport
TST (thalessec.com.cn) established via the joint investment of Shanghai Electric (shanghai-electric.com) and Thales Group (thalesgroup.com) and controlled by the Chinese investor, is a high-tech enterprise focusing on urban rail signal systems. Since the successful delivery of Wuhan Metro Line 1, China’s first CBTC line in 2004, TST has been promoting its own technologies and implementing independent innovation based on the introduction of Thales Group’s world-leading SelTrac™ CBTC technology.
The SelTrac® MS China CBTC signal system provided by TST for China’s urban rail transit industry has been supporting more than 30 urban rail transit lines with a total length of over 1,400 km in 15 cities including Shanghai, Beijing, Guangzhou, Wuhan, Nanjing, etc. Meanwhile, the company’s independently developed next-generation signal system TSTCBTC®2.0 featured by high availability and reliability due to full system redundancy has been successfully applied to Shanghai Metro Line 5, and the fully automatic operation (FAO) system has been deployed in Shanghai Metro Line 14. In addition, based on years of experience in CBTC system application and R&D, TST has designed and developed CBTC products supporting interoperability according to industry specifications, and applied them to Qingdao Metro Line 8 and Hefei Metro Line 4. TST has been committed to improving its own technologies and implementing independent innovation. We own a full set of simulation operation equipment, verification and testing platforms, and data communication and R&D laboratories, and have successively been granted over 400 software copyrights, utility models and invention patents. We have been awarded multiple honors such as “High-Tech Enterprise in Shanghai”,“Small Sci-tech Giant in Shanghai”,“Patent Pilot Demonstration Organization in Shanghai”, and “Shanghai Certified Enterprise Technology Center”, and won “Shanghai Science and Technology Award” and “2019 Shanghai Railway Quality Supplier” recently. What is more, we have passed the certifications of ISO9001 quality management system, ISO14001 environmental management system, and ISO45001 occupational health management system.
The headquarter of TST is located in Shanghai, with subsidiaries in Guangzhou, Nanchang and Wuhan, branches in Beijing and Qingdao, and project departments in Nanjing, Hefei, Shenzhen, Shijiazhuang, Ningbo, Jinan, Wuxi, Hangzhou and Zhengzhou.
