基于工作记忆的雷达管制界面信息编码设计研究

Study of Information Coding Design of ATC System Based on Working Memory

针对空管自动化系统界面设计中存在的信息编码差异性问题,开发了一个雷达管制界面信息仿真平台;利用该平台研究雷达管制系统界面飞机标牌信息的排列结构、信息色和管制界面背景色对管制员工作记忆的影响,为管制界面设计提供依据。实验以任务得分作为绩效评价指标,利用方差分析法对数据进行处理。结果发现:背景色对管制员记忆影响显著,灰色背景优于黑色背景。灰色背景下飞机标牌信息色记忆效率排序为:白色>黄色>绿色>蓝色>红色;黑色背景下信息色记忆效率排序为:白色>红色>蓝色>绿色>黄色。在雷达管制系统中,推荐方式2作为飞机标牌信息的显示结构。

n order to solve the problem of information encoding of ATC system interface design,an ATC systeminterface simulation platform was designed,the platform is used to study the relationship between wand aircraft signs information structure and signs color and background color of ATC system interface,it can provide some reference for future radar control system interface design. The task score was used as the performanceevaluation index,and the data were processed by the metliod of variance analysis. The results showed ： backgroundcolor has significant influence on working memory. Grey background is better than black background of ATC system interface. The working memory efficiency of aircraft signs color in gray background is ： white 〉 yellow 〉 green 〉blue 〉 red; the working memory efficiency of aircraft signs color in black background is ： white 〉 red 〉 blue 〉green 〉 yellow. The mode 2 is recommended as the information structure of tje aircraft signs.
