Abstract: Abstract: In view of the problems faced in the current fire rescue team command teaching and case discussion, such as non editable content, lack of interaction of scene, non intuitive display form and high production cost, this paper designs an editable fire sand table software based on Unreal Engine, which realizes the technologies of rapid scene editing, AI simulation of rescue behavior and presentation of fire sand table effect. It enables users to quickly reproduce disaster scenes and deploy combat forces, and deduce and display them according to the fire fighting stage. Through the whole process of fire sand table deduction, users can clearly show the command intention, and also facilitate the audience to intuitively and completely observe the whole fire fighting process, so as to improve the effect of battle case evaluation or case deduction.
