摘　　要：为探究安全视听信号多级认知流程,以信息流为研究思路,通过细化信息认知的具体环节,结合认知心理学相关知识,将多级认知过程分解成串联、并联、聚合和混联等不同的形式,建立混合视听信号的认知通用模型及4种不同形式下的认知模型。根据建立的"聚合-并联-串联"形式下的多级认知模型,分析认知过程中可能存在的故障模式,针对性地提出相应的防控方法,构建认知场景并将模型进行应用。研究结果表明:该模型具有充分的实用性和可行性,有利于事故防控和安全管理,为保障系统安全提供新的思路。In order to explore the multi-level cognition procedure of safety audio-visual signals,taking the information flow as the research idea,the multi-level cognition process was decomposed into different forms,such as series,parallel,aggregation and hybrid through refining the specific aspects of information cognition and combining with the relevant knowledge of cognitive psychology,and a general cognitive model of hybrid audio-visual signals and four cognitive models under different forms were established. According to the established multi-level cognitive model under the form of ＂aggregation-parallel-series＂,the possible failure modes in the cognition process were analyzed,and the corresponding prevention and control methods were proposed. Finally,a cognitive scene was constructed,and the model was applied. The results showed that the model has the sufficient practicality and feasibility,which is conducive to the accident prevention and control and the safety management,and provides new ideas for ensuring the system safety.
