摘要
针对驾驶舱仪表显示界面对飞行员工作负荷的影响机理,开展机械式和数字式仪表显示界面对飞行员工作负荷影响研究。采集飞行员生理特征参数值,基于主成分分析法对生理数据进行降维处理,利用单因素方差分析法分析飞行实验中各阶段不同显示界面被试者的工作负荷差异性。结果表明两种显示界面对被试者的各项生理指标和主观评分有显著影响。数字式仪表比机械式仪表使飞行员工作负荷较小,同时也验证了生理指标及主观评分在飞行员工作负荷评价中的有效性。
In view of the effect instrument of cockpit display interface onpilots' workload,the research on the effect of mechanical and digital instrument display interface on pilots' workload was carried out. The physiological characteristic parameters of the pilots were collected,the physiological data were reduced by the PCA,and the difference of workload of different display interface subjects was analyzed by single factor ANOVA. The results showed that the two kinds of display field had a significant effect on the physiological indexes and subjective scores of the participants. and the digital instrument makes the pilot workload smaller than the mechanical instrument,and also verifies the effect of the physiological index and the subjective score in the pilot workload evaluation.
