Research on Function Modeling Method of CBTC Regional Control Subsystem

The functional requirements of the zone controller (ZC) subsystem in the communication-based train control (CBTC) system are discussed. The Unified Modeling Language (UML) is combined with the special requirements of train operation control in CBTC to standardize the implementation process of the ZC subsystem and improve the development efficiency of the system. This article uses UML modeling to intuitively display the structure of the system, check the integrity of the system, and complete the simulation verification of the system model.
