摘要: 在CTCS-2级和CTCS-3级列车控制车载设备中，司机通过观察和操作人机界面（DMI， Driver Machine Interface）单元监控和调整列车运行状态。但是司机的错误操作、人机界面设备故障等均可能导致列车控制车载设备故障，造成运营晚点。为了对司机操作和车载设备故障进行复现，需要开发一种可以复现人机界面运营过程的系统。本文介绍了列车控制车载设备人机界面运营过程复现系统的系统框架、基本原理、人机界面日志记录包含的信息，以及人机界面运营过程复现系统4种典型应用场景，包括复现人机界面故障、支持人机界面软件调试、人机界面功能演示和自动测试人机界面功能。Abstract: In CTCS-2 and CTCS-3 Train Control Systems, The driver monitors and adjusts the train running status through observing and operating the DMI equipment. But the wrong operation and DMI equipment failure could cause the Train Control System fault, and the train delay. In order to reappear driver’s operations and on-board equipment faults, it was needed to provide a system of reappearing DMI operation process. This paper introduced the system frame and basic principles of the DMI Operation Reappearing System, described the useful information which was included in the DMI logs, introduced four typical applications about reappearing the DMI defaults, debugging the DMI software, displaying the DMI functions and testing the DMI functions automatically.
