On the subway train, the train driver can use a dedicated wireless onboard radio to make group calls with the central dispatcher and station duty officer; at the subway station, passengers can obtain train arrival information through the information system and station broadcast system; in the subway station duty room, the station duty officer communicates operational, management, and maintenance matters with colleagues via a dedicated telephone…

These seemingly routine actions require a large and complex system to support them. China Electronics Technology Group Corporation Far East Communications' rail transit dedicated network communication solution plays an important role in this. "The rail transit dedicated network communication solution uses an intelligent method to build a comprehensive business communication network, enabling intelligent train command and dispatch, digital equipment inspection and maintenance, and the construction of on-demand emergency communication." said Jiang Guohua, an expert at Far East Communications.

In terms of intelligent train command and dispatch, the scheme relies on the urban rail cloud platform and provides cloud services through a virtualized resource pool, enabling unified deployment and dynamic resource allocation of urban rail business applications. In terms of vehicle-ground wireless communication, the scheme can provide a stable and reliable vehicle-ground wireless transmission network for various vehicle-mounted services, meeting the operational needs of rail transit and effectively improving passenger service quality.

In underground passages, if power outages or network outages occur during tunnel construction and operation, establishing emergency communication to restore the normal network is crucial. By deploying portable emergency communication equipment, the rail transit dedicated network communication solution effectively addresses extreme conditions such as no network and no power in special scenarios, opening up information transmission channels for tunnel emergency rescue and disaster relief, effectively improving the ability and efficiency of emergency rescue and disaster relief, and ensuring the safety of people's lives and property.

In addition, the rail transit dedicated network communication solution proposes an intelligent operation and maintenance solution centered on "data + algorithm", mining data patterns, improving the understanding of operation and maintenance data, intelligently assisting fault diagnosis, and helping operation and maintenance personnel quickly identify faults and problems that are difficult for humans to reach. At the same time, the scheme can accurately warn of system risks, transforming passive maintenance into proactive maintenance, promoting the continuous evolution of maintenance work, and achieving improved efficiency and effectiveness of maintenance work through digital and intelligent means.

 
Currently, this solution has been successfully applied to 52 cities and 224 urban rail transit lines nationwide, providing important guarantees for safe operation, improved transportation efficiency, and improved service quality. Next, Far East Communications will deeply integrate new information and communication technologies such as 5G, cloud computing, big data, and artificial intelligence with industry applications, research intelligent communication platforms, intelligent multimedia dispatch systems, and other product solutions to help build a digitally driven smart subway, achieving safe and pleasant passenger travel and more intelligent and efficient operation and maintenance.
