摘要:
针对列控中心(TCC)的工作原理和主要功能,在CTCS-3列控仿真平台的基础上,提出TCC仿真子系统的整体架构、通信接口设计方案,实现轨道电路编码、有源应答器报文编制、临时限速和信号降级处理、区间改变运行方向、区间信号机点灯等主要功能。通过二维可视化操作界面,实时显示轨道区段的码序变化、区间运行方向,查看通信报文数据,模拟通信故障等。结合Unity3D开发环境下的三维TCC机柜模型,动态展示与其他子系统的通信状态。TCC仿真子系统将逻辑功能的实现与可操作性、可视性相结合,具有良好的实践教学意义。

Abstract:
Aiming at the working principle and main functions of Train Control Center (TCC), this paper put forward the overall architecture and communication interface design scheme of TCC simulation subsystem on the basis of CTCS-3 Train Control simulation platform, and implemented the main functions such as track circuit coding, message compilation of active balise, temporary speed limit and signal degradation processing, section changing operation direction, section annunciator lighting, etc. TCC simulation subsystem can display the code sequence change of track section, running direction of section, check the communication message data and simulate the communication fault in real time through two-dimensional visual operation interface, and combined with the 3D TCC cabinet model in the Unity3D development environment, dynamically displays the communication status with other subsystems. The subsystem combines the implementation of logic function with operability and visibility, which has good practical teaching significance.
