基于CPN的飞机驾驶操纵过程建模及工效分析

驾驶舱人机界面的设计直接关系到飞行员在飞行任务中的操纵表现和飞行安全.分析了飞机驾驶操纵过程中的人机交互特性,基于着色Petri网构建了飞机操纵过程模型并给出了模型的公理化定义.提出了任务可达性,飞行员认知负荷和基于熵值的操纵程序复杂性评估方法,能够实现在驾驶舱设计初期对飞行员认知负荷与操纵过程的分析.结合某型飞机的起飞中断过程给出了操纵过程建模与工效分析实例,表明模型与方法的有效性.

Aircraft Control Process Modeling and Ergonomics Analysis Based on CPN

The design of cockpit human-machine interface has direct effects on the piolt performance and flight safety during flight task.Human-machine interaction characteristics during the control process are analyzed.The aircraft control process model is built based on the colored Petri nets (CPN) and the axiomatic definition of the model are given.Assessment methods of the task accessibility,the cognitive load and the control process complexity are proposed,which realized the analysis of the control process ergonomic parameters in the early stage of the cockpit design.At last,an application case of control process modeling and ergonomics analysis combined with rejected takeoff process of a certain type of aircraft is given to illustrate the feasibility of the model and the mothed.
