基于信息融合技术的复合式火灾探测器

The Multi-sensor Fire Detection Based on Information Fusion Technology

在火灾探测中对单一的火灾特征参数信息进行判断和识别的探测器,易受到环境的干扰,限制了其探测性能,系统的高误报率问题比较突出;复合式火灾探测器采用信息融合技术进行多火灾特征参数信息的判断和识别,提高了火灾探测的可靠性和准确性。介绍了复合式火灾探测器中多传感器的选择。结合火灾探测独特的三层结构(数据层、特征层、决策层)讨论了数据融合技术在火灾探测系统中的应用,并对多传感器在数据层信息融合的模型结构进行了归纳。

That the fire sensors detesting the fire only by single characteristic parameters leads to increasing false - alarm rate. The single characteristic parameters fire sensor is vulnerable to environmental interference, and the performance of its detection is limited. The high false - alarm rate is quite conspicuous in this system. In comparison, the composite fire detectors improve the reliability and accuracy by using information fusion Technology for multi - fire parameters of the judgment and identification information. This paper describes the compound fire detector in the multi - sensor choice. The article discussed the data fusion technology in fire detection system in the application, combined the unique three - tier structure （ data layer, layer characteristics, and the decision - making level） of the fire detection. In the multi -sensor data fusion -information model structures were summarized in data layer in the end.
