由实物模型子系统、控制子系统和智能调度子系统搭建基于运行图驱动的列车运行控制半实物仿真系统。采用实物微缩模型与抽象模型相结合的方法,构建列车运行控制过程的半实物仿真环境及仿真算法;基于DxdcNet/LocoNet通信协议,定义用于各子系统间数据交互的数据格式及通信协议;采用C#编程语言编制相关系统软件。对以京津城际铁路为背景搭建的基于运行图驱动的列车运行控制半实物仿真系统进行测试,结果表明:可以直观地仿真三显示、四显示和准移动闭塞模式下的列车运行全过程,在1h内完成全日运行图的行车组织过程演练并获取相关数据,为列车运行计划的编制和安全实施提供科学依据。该系统已投入实际使用,并在调度指挥教学、运行图动态性能检测等方面均取得了良好效果。

The hardware-in-the-loop simulation system for train operation control based on working dia- gram driven was constructed by physical model subsystem, control subsystem and intelligent dispatching subsystem. The hardware-in-the-loop environment and simulation algorithm for train operation control process was built by integrating the physical small-scale model with the abstract model. The data format and communication protocol for data exchange between each subsystem was defined based on DxdcNet/Lo- coNet communication protocol. The related system software was programmed with C # programming lan- guage. With Jing-Jin intercity railway as the background, the hardware-in-the-loop simulation system based on working diagram driven for train operation control was constructed and verified. Results show that the whole process of train operation under three-aspect, four-aspect and quasi-movahle block modes can be directly simulated. The process drilling for train operation organization of the working diagram for whole day can be completed in one hour and the relevant data can be obtained, which provides the scientific basis for the workout of train working diagram and safe implementation. The system has been put into service and achieved good effect in traffic control teaching, the dynamic performance detection for working diagram and so on.
