Research on Visual Evaluation of Coal Safety Management

In order to improve the cognitive efficiency and cognitive accuracy of safety management problems in the management information system of coal enterprise managers, this paper focuses on the effect of the display mode of safety production information in management information system. In this paper, the visualization content is divided into real-time information and statistical summary information of safety production sites; we select several representative visual methods respectively, such as vector cartoon, photograph, monitor, virtual reality, line chart, scatter plot, histogram and radar map. Using eye movement experiments to capture eye movement indicators for each visual mode, through the factor analysis filtering and merging, we finally build three evaluation indicators：eye movements numbers （ＥＭＮ）, saccade distance total （ＳDＴ）, average fixation time. Finally, the TOPSIS method is used to evaluate the visualization method. The results show that based on the real-time information, photos and monitoring display are significantly better than other display methods. For the summary information, the display effect of the line graph is significantly better than that of the other three display methods.
