Design and development of flame spectrum data acquisition and analysis system
A flame spectrum data acquisition and analysis system is designed to collect flame spectrum data in complex and dynamic environments and extract flame spectrum characteristics with high stability and consistency.This system aims to provide more reliable design parameters for developing flame simulators.Firstly,red/ultraviolet sensors with detection bands at 3.8 μm,4.4 pm,5.0 pm,and 185 nm～260 nm are utilized as signal acquisition terminals along with the design of filter and amplifier circuits.Secondly,a frequency decoupling method is proposed for spectral data analysis based on microcontroller A/D conversion of signals.The spectral data from each detection band are decomposed into real flame spectral data and interference spectral data using this method,which enables calculation based on the decoupled spectral data.Finally,five flame spectral features are extracted from the analyzed results obtained by this system.Experimental results demonstrate that these extracted flame spectrum features exhibit higher reliability and possess significant reference values for designing flame simulators.
