建筑火灾风险动态评估实体关系图

摘要

建立现有建筑个体火灾风险动态评估系统的实体关系图,介绍实体关系图的设计步骤、思路和方法,包括核心实体、相关实体、关联和关系、属性和规范化、细节调整等.给出了建筑个体火灾风险动态评佑系统实体关系图.利用该方法可对现有建筑个体火灾风险进行动态评估,当现有建筑个体的结构、用途、内部或外部火灾危险源发生变化时,通过实体关系图进行火灾风险分析,确定风险等级.%The entity relationship diagram of existing building individual dynamic fire risk assessment system was built, and the design process. idea and method of entity relationship diagram were introduced. The entity relationship diagram of building individual dynamic fire risk assessment system was presented.The existing building dynamic fire risk og the individuaL can be assessed by the method, and when the existing building individual structure , purpose, internal or external fire hazard changes,the entity relationship diagram can be used to perform the fire risk analysis and determine the risk degree.
