摘要: 根据城际铁路列控系统中离散逻辑跳转和连续时间行为交织的特征，采用Matlab软件中的Simulink和Stateflow结合的方式实现车载控制子系统混成行为的建模与仿真，分析不同速度下列车超过紧急制动触发速度后产生的紧急制动距离以及列车实际运行曲线。结果表明：建立的紧急制动触发模型所产生的制动距离满足动车组厂家给出的要求，并且具有一定的安全余量；该建模方法直观高效，易于理解，模型能够很好的描述系统特性。仿真结果也可为车载控制子系统的设计和实现提供一定的支持。Abstract: According to the characteristics of discrete logic jump and continuous time behavior in the inter city railway train control system, this article adopted the combination of Simulink and Stateflow in Matlab to model and simulate the hybrid behavior of train control system, analyze the emergency braking distance of the train and train running curve at different speeds after the train exceeded the emergency braking trigger speed. The results showed that the emergency braking distance generated by model met the requirements of CRH EMU manufacturer, had a certain safety margin. The modeling method is simple and efficient, the model can better describe the characteristics of the system. The simulation results can provide data support for designing and implementation of the on-board system.
