A Fire Detection Algorithm Using Second Order Statistics

Klose, J. and Siebel, R., 1991. A Fire Detection Algorithm Using Second Order Statistics. Fire Safety Science 3: 943-953. doi:10.3801/IAFSS.FSS.3-943


A detection algorithm is presented, based on the comparison of the short- and long-term power spectral densities of monitored input signal sequences from Tire sensors'. The detector adapts slowly varying changes in the f i t and second order statistics of the monitored signals, which may occur due to environmental influences. The algorithm is as well suited for single- and multiple input detection. A recursive implementation reduces the calculation effort. Experimental results are presented, concerning the detection capability and the false alarm resistance of the detection algorithm in realistic environmental conditions.
