According to the structure of the CTCS-1 train control system and the complexity of its on-board subsystem functions, a model-based method was used to implement the modeling and simulation of the on-board subsystem that using the combination of Simulink and Stateflow in MATLAB software. Then this paper analyses the emergency braking distance and the actual running curve of the train when the following trains at different speeds exceed the emergency braking trigger speed. The results show that the braking distance generated by the established emergency braking trigger model meets the requirements given by train manufacturers, and has a certain safety margin, which also verifies the correctness of the model. The modeling method is intuitive, efficient, visual, and easy understand that the model can well describe the characteristics of the system. The simulation results can provide certain support for the design, research and implementation of the on-board control subsystem of the CTCS-1 train control system.
