On July 7, China Railway Electrification Engineering Group Co,.Ltd. Urban Railway Company participated in constructing the first national demonstration line of train autonomous operation system-Qingdao Metro Line 6 Phase I Project successfully applied the communication system of the whole line.
The Urban Railway Company of China Railway Electrification Engineering Group Co,.Ltd is mainly responsible for constructing and installing communication systems, train autonomous operation systems, automatic fare collection systems, platform door systems, intelligent operation systems, cloud platform systems, and FAS and gas fire extinguishing systems of Qingdao Metro Line 6 Phase I Project. The communication system is also known as the "neural network" of the subway. Its completion marks that Qingdao Metro Line 6 has completed the related debugging work of dedicated transmission, dedicated telephone, dedicated wireless, and other systems, as well as system integration, which ensures the realization of essential functions such as dispatching telephone and dedicated wireless signal coverage.
For the first time, Qingdao Metro Line 6 has adopted the technology of sliced packet network (SPN). The system bandwidth of the equipment configuration is 100GB/S, which can not only meet the rapid growth of bandwidth demand brought by the new business of the metro equipment system but also support the physical isolation between different types of business and provide differentiated link protection. It provides a data transmission network with high reliability, low delay, and large bandwidth for each equipment system.
