DMI运营过程复现系统的设计与实现

Design and Implementation of DMI Operation Reappearing System

在CTCS-2级和CTCS-3级列控车载设备中,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、DMI设备故障等均可能导致列控车载设备故障,造成运营晚点。为了对司机的操作和车载设备故障进行复现,需要开发一种可以复现列控车载设备DMI运营过程的系统。首先介绍列控车载设备DMI运营过程复现系统的系统框架和基本原理;其次介绍在DMI运营过程复现系统中DMI日志记录的使用方法;最后介绍车载主机模拟工具的一些关键技术。

For onboard equipment of CTCS-2 and CTCS-3 train control systems, the driver monitors and adjusts the train running status through observing and operating DMI equipment. The driver＇s wrong operation or DMI equipment failure can cause train control system faults that may lead to an operation delay. In order to reappear driver＇s operation and onboard equipment faults, it needs to provide a system for reappearing DMI operating process. This paper firstly introduces a DMI operation reappearing system, including the system frame and basic principles, then it introduces the method of using the DMI log file. And finally it introduces some key technologies of the on-board equipment simulation tools.
