摘要: 针对正常情况下CTCS-2级列控系统和CTCS-3级列控系统之间的等级转换,探讨了一种基于有色Petri网模型的系统建模方法。模型中引入非周期消息模型,模拟在GSM-R网络中RBC(无线闭塞中心,Radio Block Centre)与车载设备之间消息的传送过程,并建立基于有色Petri网的等级转换控车场景模型,讨论在不同消息重发时间间隔、不同列车速度对等级转换场景完成成功率的影响。验证了该建模方法的有效性,说明了影响等级转换成功率的因素。

Abstract: For the normal circumstances level transition between CTCS-2 and CTCS-3 train control system, this paper discusses a modeling method based on colored Petri net system which introduces a non-periodic message model. It simulates the message delivery process between RBC and vehicle devices in the GSM-R. And it establishes the level transition control scene model based on colored Petri net, discusses the affect of different messages retransmission interval and different train speed to level transition scene complete success rate. This paper verifies the validity of the modeling method, illustrates the factors affecting the success rate of the level transition.
