为提高系统安全水平,进一步丰富安全系统学理论内容,对微系统内人机界面的安全信息流过程、模型及其应用进行深入研究。论述安全信息流与人机交互过程理论,为模型构建奠定理论基础;运用安全模型原理,从信息传播角度建立人机界面的安全信息流模型并分析模型的内涵和意义;将所建模型应用于具体情景的仿真模拟,以验证其适用性和合理性。研究结果表明:模型刻画了系统内安全信息流动轨迹,有利于揭示系统安全演化行为机理,对提高系统安全水平具有重要的理论指导意义。

In order to improve the level of system safety and further enrich the theoretical contents of safety systematics,the process and model of safety information flow for the human-machine interface in the micro system and its application were studied deeply.The theories of safety information flow and human-machine interaction process were discussed,which laid the theoretical foundation for the model construction.A safety information flow model of human-machine interface was established from the perspective of information propagation by using the principle of safety model,and the connotation and significance of the model were analyzed.The model was applied in the simulation of the specific scene to verify its applicability and rationality.The results showed that the model characterized the flow track of safety information in the system,which is helpful to reveal the evolutionary behavior mechanism of system safety,and has important theoretical guiding significance for improving the safety level of system.
