AI Technical Summary

Technical Problem

Existing train control systems are diverse in type, difficult to maintain, and costly, making it difficult to achieve efficient and intelligent train control. Interconnection between systems is also difficult, and it is hard to support automatic driving and unmanned station management.

Method used

The train control system (NF-CBTC) that uses near-field and mid-to-far-field communication in coordination provides two-way interactive data between the train and the ground, and between trains, through the combination or redundancy of near-field and mid-to-far-field communication. This enables train position tracking and occupancy checks. Near-field communication provides backup functionality in case of mid-to-far-field communication failure, simplifies trackside equipment, and supports autonomous train operation and automatic block control.

Benefits of technology

It improves the reliability and efficiency of train operation, simplifies maintenance work and costs, supports automatic driving and train operation on different track systems, adapts to various environments, achieves multiple redundancies in train positioning and location tracking, and is easy to implement fully electronic interlocking control and autonomous operation.
