贮木场原木楞堆火灾信息探测方法的评价研究

Evaluation on Fire information Detection of Log Piles in Log Yard

本项研究结合各种火灾信息探测方法的特点,运用AHP法构建了贮木场最佳火灾探测方案及评价指标体系。研究结果表明,楞堆燃烧阴燃阶段和燃烧蔓延阶段是最佳火灾探测时期;由于外界自然环境的影响,在楞堆阴燃阶段,抗干扰性在火灾探测方案中占有重要的位置;在燃烧蔓延阶段,由于释放大量的热,耐热性占据了重要的位置;对于贮木场火灾探测,及时性指标占有很重要的位置;在所有火灾探测方法中,复合式火灾探测方法是最佳火灾探测方法,其次为感烟探测法,再次为感温探测法和气体探测法。

Combing the characteristics of different kinds of fire information detection,the evaluation index system of the optimum fire information detection of log yard was constructed using AHP.Smouldering and combustion spread stage are the optimum time for fire detection.Owing to the effects of outer external natural environment,during the stage of smouldering,anti-interference performance plays very important role in fire detection plan.In the stage of combustion spread,since the release of a lot of heat,heat resistance has importance place.Besides,timeliness is quite crucial for fire detection of log yard.Among all the methods considered,compound fire detection method is the optimum method,next come the feeling smoke detection method,the effects of feeling temperature detection method and gas detection method were not good as the aforementioned two methods.
