摘要
为研究消防安全疏散标志空间方向信息传递效能,以吊牌式与嵌入式2类常用消防安全疏散标志为研究对象,设计空间方向信息传递效能模拟实验,并提出对策措施。结果表明:吊牌式消防安全疏散标志空间角度与空间方向信息传递效能成反比;嵌入式消防安全疏散标志空间角度为10°时,空间方向信息传递效能最强,但空间角度为5°时实用程度最佳;适当空间角度可增加消防安全疏散标志可视面积,增强其空间方向信息传递效能。
To explore the effectiveness of spatial directional information transmission of fire safety evacuation signs, we designed a simulation experiment on the effectiveness of spatial directional information transmission by using two types of commonly used fire safety evacuation signs: hangtag and embedded, and the countermeasures were put forward. The results indicate that the spatial angle of the hangtag fire safety evacuation signs is inversely proportional to the effectiveness of spatial direction information transmission. When the spatial angle of embedded fire safety evacuation signs is 10°, the spatial direction information transmission effectiveness is the strongest. But when the spatial angle is 5°, the practical degree is the best.Suitable spatial angle can increase the visual area of fire safety evacuation signs, thus enhance its transmission effectiveness.
