列车速度跟踪显示方式的人机工效研究

Research on ergonomics of locomotive velocity tracing interface

速度跟踪显示装置作为列车行车安全保障的核心设备,其显示方式的科学性与易读性对于保障列车安全运行、防止冒进与超速起着极其重要的作用。针对目前常用3种速度跟踪显示方式,从界面设计与人的认知特性、人的操作可靠度等因素出发,设计了八种典型的驾驶操作任务,对比研究了三种速度跟踪显示方式在不同的任务等级、任务发生的距离间隔以及被试者的经验水平下的操作可靠性。实验结果表明:曲线式速度跟踪显示方式受外界因素干扰波动较小,而且操作不易出错,优于表盘式和柱状式速度跟踪显示方式。

Velocity tracing interface is the core of the security equipments of the locomotive. Its operation safety, easiness and reliability play a important role to enhance locomotive operation safety and guarantee safety, high effi- ciency of railway transportation. At present, there are three main kinds of velocity tracing interface. The first one is the curve mode, such as LKJ2000 in China, the second is the dial mode which is used by DMI interface of locomotive ATP system, and the third is the column, such as ATC interface. Based on the cognitive characteristics of human being and reliability of operation, three different interface designs of train velocity tracing are analyzed and eight typical experi- mental tasks are designed. And there is a comparative research on the reliability of operation about three different ve- locity tracing interfaces, according to different task levels, distances and people＇s experience levels. The results show that the curve mode is slightly fluctuated by the environment and with few mistakes, then better than the dial mode and the column mode.
