摘要
研究火灾事故爆发点准确判断问题。火灾在燃烧过程中,时空上失去控制,火灾的烟雾、火焰在时空上发生了整体移动。初始爆发点特征也会发生、退化、移动。传统的判断方法多半是通过寻找火灾爆发初期的特征认定,完成火灾爆发点的判断的。一旦特征发生较为明显的移动,爆发地点也会发生较为明显的判断失误。提出利用动态能量燃烧痕迹特征的火灾事故爆发点判断方法。通过判断火灾发生过程中,燃烧能量的变化趋势,判断火灾发生的初始位置,排除特征移动的干扰。实验证明,动态方法实现了较为准确的判断火灾爆发点的认定,并提高了火灾检测效率。
Study the accurate location of the outbreak of fire accident points. The combustion process of fire is out of control in the time and space. This paper proposed a determination method of fire accident flashpoint with the char- acteristic of dynamic energy burn marks. In the process of fire, the change trend of the combustion energy and the in- itial position of the fires are by determined in order to exclude feature mobile interference. Experimental results show that the dynamic method achieves a more accurate judgment of the point of fire outbreaks, and improves the efficiency of the fire detection.
