许多研究人员都把多传感器探测当作区分火灾源与噪扰源的主要手段来研究。多传感器探测器能从多个角度监测有焰火、无焰火和噪扰源所产生的各种特征。本文将介绍一个利用带多元气体传感器的原型高级火灾探测器完成的大 小规模试验计划。初步分析表明 ,研发出合理的多元气体传感器定位导向就能够探测具有特定阈值火焰规模 (即放热速率 )的火灾。区分有焰火源、无焰火源和噪扰源可利用阈值浓度或CO2上升速率 (针对有焰火源的识别 )和CO或CO2 上升速率 (针对无焰火源的识别 )来实现。此外 ,研究人员还对原型探测器和商品感烟探测器的探测时间作了比较 ,并注意到探测时间的缩短。
Many researchers have studied multisensor detection as the primary means of distinguishing fire from noise sources. Multisensor detectors monitor various characteristics of a fireworks, flameless fire, and noise sources from multiple perspectives. This article will introduce a pilot project using a prototype high-level fire detector with multiple gas sensors. Preliminary analysis shows that developing a reasonable multivariate gas sensor orientation can detect a fire with a specific threshold flame size (ie, heat release rate). Differentiating pyrophoric sources, flameless sources of ignition, and sources of noise can be achieved using threshold concentrations or rates of CO2 rise (for pyrophoric sources) and CO or CO2 rates (for pyrotechnic sources). In addition, the researchers also compared the detection times of prototype detectors and commercial smoke detectors and noticed the shortening of detection time.
