防雷安全标志图形符号关键技术研究

Research on Key Technologies of Graphic Symbols of Lightning Protection Safety Signs

不依赖于语言文字向人们传递防雷安全信息的图形符号,可指导人们采取行动避免雷电对人身安全和健康的伤害。本文分析了雷电对人身伤害的主要方式、防雷标准中设置标志牌的要求严格程度,根据安全标志图形符号表示规则和设计要求,提出了防雷安全标志图形符号。结果表明:防雷安全标志包括禁止悬挂、禁止贴近、当心雷电、必须离开和避雷场所等5种基本图形符号,其中避雷场所可根据其与人所在的相对位置添加“人的移动”指向,组成若干种提示标志。通过对图形符号理解性和对象相关性测试,识别正确率分别为70.5%和71.7%。

Graphic symbols that do not rely on language to convey lightning protection safety information can guide people to take actions to avoid the harm of lightning to personal safety and health. This paper analyzes the main ways of personal injury caused by lightning and the strictness of the requirements for setting signboards in lightning protection standards, and puts forward the graphic symbols of lightning protection safety signs according to the representation rules and design requirements of graphic symbols of safety signs. The results show that the graphic symbols of lightning protection safety signs include No hanging, No approaching, Warning lightning, Must leave and Lightning safety places. Among them, Lightning safety places can add direction auxiliary signs according to their relative position with people to form several prompt signs. The recognition rate was 70.5% and 71.7% respectively through testing graphic symbol comprehension and testing symbol referent association.
