基于DMI的列控车载设备运用过程复现系统关键技术研究

Key Technology of DMI-based ATP Operation Reappearance System

在列控车载设备运用过程中,通过人机界面(DMI)单元以便于理解的方式引导司机完成控制操作,进行列车速度监控。在实际的运营过程中,由于列控车载设备故障、司机操作等原因可能对运营造成影响,为了对运营过程进行分析,需要一种可以复现列控车载设备运用过程的系统。首先介绍基于DMI的列控车载设备运用过程复现系统框架和基本原理;其次介绍将DMI发送给列控车载设备主机的消息还原成正确的司机操作的关键技术,最后对司机操作进行分类,并给出模拟各类司机操作的方法。

The driver monitors and adjusts the train running status through observing and operating DMI equipment when ATP is used for controlling the train speed. So train operation will be affected due to ATP failure or the driver＇s wrong action. In order to analyze the train operation, it needs a system to repeat ATP operating process. This paper firstly introduces the system frame and basic principles of a DMI-based ATP operation reappearance system, and then it introduces the key technology of converting the messages from DMI to on-board equipment into the correct driver operation. Finally it classifies driver operation and gives the methods of simulating, the driver operation.
