嵌入式安全疏散标志空间结构研究与设计

Research and design of space structure of embedded safety evacuation signs

为提高嵌入式安全疏散标志视觉吸引力,开展空间方向信息传递效能模拟试验,分析不同空间角度嵌入式安全疏散标志对选择反应时、预期选择相符度及选择自信程度的影响,并通过消防演习进行验证,得出最优空间角度。最后依据研究结果设计一种空间立体嵌入式安全疏散标志。结果表明:整体上,空间角度越大,可视面积越大,选择反应时越短,预期选择相符度、选择自信程度越高。空间角度为5°时空间方向信息传递效能最强,参演人员平均逃生时间最短,且选择非熟悉出口比例增加。空间立体结构嵌入式安全疏散标志能够提高火灾应急疏散效率。

In order to improve visual appeal of embedded safety evacuation signs,a simulation test of their spatial direction information transmission efficiency was conducted.Influence of their different spatial angles on subjects'choice response time,expected choice conformity and choice confidence was analyzed,and verified through fire drills to get the optimal space angle.Finally,a kind of spatial three-dimensional embedded safety evacuation signs was designed according to research results.The results show that generally the larger the spatial angle is,the larger the visible area there will be,the shorter the choice response time and the higher the expected choice conformity and choice confidence will be.When the angle is 5°,spatial direction information transmission efficiency is the strongest,with the average escape time of participants being the shortest,and proportion of choosing unfamiliar exits increases.The embedded safety evacuation sign with a spatial three-dimensional structure can effectively improve efficiency of fire emergency evacuation.
