Abstract:
    The system includes signal acquisition module, digital filtering module, and analyzing process module. In finite time domain and frequency domain, the signal acquisition module collects signals in time domain, signals in frequency domain continuously in equal interval as well as collects intensity signals corresponding to signals in time domain. Using digital filtering module filters out not needed interference signal from the colleted frequency signals. Analyzing process module carries out frequency analysis for frequency signals with interference being removed. Using FFT calculates intensity value of signal under corresponding frequency. Since state of burning flame is detected through characteristic frequency of burning flame, the detected result is more true and accurate.
