| Abstract: | In this paper,the operating principles, structural styles and performance characteristics of the semiconductor type, infrared absorption type, fixed potential electrolyte type gas sensors and the developing intelligent gas sensor are introduced,their applications in fire detection field are also analyzed. Additionally this paper suggest that attribute level of multi sensor fire detection should adopt characteristics data fusion model and provide an effective exponential windowing algorithm as well as its relevant hardware design. |
