根据现场调研和视频观察,对数字化控制系统与传统的模拟控制系统进行了对比分析,发现数字化控制系统人机交互具有操纵员角色转变、认知负荷大、硬控制向软控制转变、人机界面交互更加丰富的特征.通过人机交互复杂性的关键因子,即操纵员因素、任务因素、界面管理因素以及操作因素,分析了它们对人因失误的影响,以期为降低人机交互的复杂性提供理论支持.
According to field investigation and video observation, the new characteristics of digital human-machine interaction in digital control system are identified by comparing with the traditional analog control systems, such as the transformation of operator' s role, the increases of cognitive load, the transformation from hard control to soft control and the more ample human machine interface. Through the four key influencing factors of the complexity of human machine interaction, named operator, task, interface management and manipulation, the effects on human factor error are analyzed, expecting to provide theoretical support for reducing the complexity of human machine interaction.
