Construction and application of safety information flow model for human-machine interface of micro system

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.
