| 摘 要： | 研究准确识别飞机火警系统,由于飞机火灾火势猛,突发性强,飞机火警系统误报率较高.为提高识别火警准确率,提出一种D-S证据理论的数据融合方案.对机舱内燃烧时的温度、烟雾浓度、光亮度等火情特征参量进行判断,分析特征参量的内在特性和常见的火情信息处理流程.采用多传感器多周期的时空融合方法对火情信息进行识别,得出火灾的四种不同状态类型:明火、阴燃火、无火灾、无法识别,并进行仿真,结果表明,根据D-S理论进行数据融合结果对火警识别具有较高的准确度和可信性,为设计提供了依据. |

| Abstract: | For high rate of false fire alarming in the airplane,data fusion was proposed based on D-S theory.Temperature,smoke density,lightness and other fire features were described,which were produced by some material burning in the airplane.Some inner features were analyzed,and common fire information processing flow was given.Information from multi-sensors was fused with different measurement cycles,which got four types of results: open fire,smoldering fire,no fire and no identification.The result of simulated experiment shows that the application of temporal-spatial information fusion in fire alarming brings higher accuracy and reliability. |
