农村水电站安全隐患识别的视知觉眼动特征

Space Permissive and Eye Movements on Rural Hydropower Station Safety Hazard Identification

农村水电站安全隐患识别是消除安全隐患、防止事故发生、改善劳动条件的必要环节。为提高安全隐患识别效率,依据拓扑心理学分析安全隐患的物理限制、物理属性与语意约束,进行多水平信息深加工分析,以农村水电站作业人员为被试人员进行眼动实验研究,提取安全隐患识别的眼动特征。结果发现:(1)安全隐患识别时,初次注视时间差异性较小;(2)部分作业人员进行安全隐患识别时,对安全隐患识别累计停留时间随着时间推移逐渐减少;(3)作业人员对各情景中安全隐患识别能力差异较大,常识性安全隐患较其他类型安全隐患容易识别。

Potential safety hazard identification is a necessary procedure to eliminate hidden dangers, prevent accidents and improve working conditions. In order to improve the efficiency of safety hidden danger identification, it analyzes topological psychology physical limitations of potential safety problems, physical attributes and semantic constraints, multi-level information on deep-processing analysis, rural workers hydropower as subjects performed eye movement experimental studies, extracted safety hazards and identified eye features. The results show that： （1）When security risks identification, the initial fixation time difference is small. （2）The section operating personnel to identify safety problems, the time to identify safety problems has decreased as time goes by. （3）Workers＂ ability to identify differences, common-sense secur- ity risks compared to other types of safety hazards are easy to identify.
