Research on Multi-Resolution Modeling of Intercity Railway Train Control System

The intercity railway train control system is a new system that extends the automatic train operation (ATO) function on the basis of the traditional train control system and has been successfully applied on the Guanhui Line. Early establishment of a simulation system platform with wide applicability for the system can play an important role in shortening system development time, testing system operation, and training field workers. Multi-resolution modeling can describe the system from different levels and different angles. The modeling results can be combined with distributed simulation to establish a corresponding simulation application platform. Based on the different levels of detail in information interaction, this paper adopts multi-resolution modeling method and selects the operation scenes of train automatic operation and precise stop at the station to establish the train section status model, train pulling in model, and ATO control realizing model to perform the system from low, medium, and high resolution levels. In addition, choose the formal method based on the DEVS-based MRME to formally describe the model, verify the rationality of the model, and lay a theoretical foundation for the subsequent model research and simulation platform establishment.
