Combined with the power spectrum analysis method of digital signal processing, the spectral characteristics of the fire signal are analyzed. By calculating the difference of the power spectral density of the fire signal and the non-fire signal and the processing and analysis of a large amount of experimental data, the power spectrum statistical detection algorithm is studied Application of fire detection signal processing.
