基于多分辨率建模和高层体系结构,对CTCS-3级列控系统进行仿真研究。根据CTCS-3级列控系统的结构,选择无线闭塞中心(RBC)、列控中心(TCC)、应答器信息传输模块和车载安全计算机4个关键模块组成控车模型。采用多分辨率建模方法,根据信息交互细节层次的不同,将控车模型中的不同模块划分为低、中、高3种分辨率模块。应用HLA仿真技术,构建控车模型中联邦对象模型和成员之间的属性公布与订购关系,应用RTI软件实现控车模型的仿真过程。实现了如下仿真场景:控车模型联邦与RTI软件的连接与退出;不同分辨率情况下的RBC与TCC信息交互生成行车许可;车载安全计算机绘制计算目标距离曲线;列车行驶视图显示。仿真结果验证了多分辨率建模方法在CTCS-3级列控系统仿真中的可行性。
Based on multi-resolution modeling and High Level Architecture (HLA),CTCS-3 train control system simulation was studied. According to the structure of CTCS-3,four key modules including Radio Block Center (RBC),train control center (TCC),the balise information transmission module and the on-board vital computer were chosen to constitute the train control model. Based on the difference of the information transmission level,using multi-resolution modeling method,the different modules of train control model were divided into high,middle and low resolution module. The HLA simulation technology was used to construct the property publication and the ordering relationship of train control model federation object module and federation member,and the train control simulation process was realized with RTI software. The simulation realized the following simulation scenes,which included the connection and disconnection of the train control model and RTI software,the movement authorization generation realized by RBC and TCC in different resolution,the on-board vital computer computed object distance curve and train running view display,etc. The simulation results have validated the feasibility of the multi-resolution modeling method in CTCS-3 simulation.
