摘要
为了探讨灭火作业中泡沫(水)射流建模和控制问题,研究了泡沫(水)射流射程的影响因素。采用实验的方法得到消防炮工况参数和外界环境因素共同作用下的泡沫(水)射流射程数据,使用随机森林算法对泡沫(水)射流射程进行分析与建模,分别给出了射程各个影响因素的重要度排序,结果表明流量和仰角分别是泡沫射流射程和水射流射程最显著的影响要素,且风对于泡沫射流射程也有着相当重要的影响。
In order to discuss the modeling and control of foam(water)jets in fire-fighting operations,the influencing factors of the range of foam(water)jets were studied.The experimental method was applied to obtain the foam(water)jet range data under the combined action of the fire cannon parameters and external environmental factors.The range of foam(water)jet was analyzed and modeled through the random forest algorithm which respectively gave the order of the importance of each factor.The results showed that the flow rate and elevation angle were the most significant influencing factors and wind also had an obvious influence on the range of the foam jet.
