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, the CTCS-3 train control system is simulated. According to the structure of CTCS-3 train control system, four key modules of RBC, TCC, transponder information transmission module and on-board safety computer are selected to form a control model. Using multi-resolution modeling method, according to the different levels of information exchange, the different modules in the control car model are divided into three kinds of low, medium and high resolution modules. HLA simulation technology is applied to construct the federation object model and the relationship between member publicity and order in the control car model, and the RTI software is used to realize the simulation process of car control model. The simulation scenarios are as follows: the federation of control model and the RTI software are connected and withdrawn; the RBC and TCC information are exchanged with each other to generate driving license under different resolutions; the onboard safety computer draws the calculated target distance curve; the train driving view is displayed. Simulation results verify the feasibility of multi-resolution modeling method in simulation of CTCS-3 train control system.
