Abstract
As a result of the work the comprehensive method for enhancing reliability of decisions was developed upon detection of fire against the background of dynamic optical interferences. The additional informative parameters were analyzed. The general principles of the method are formulated. The temperature and spectrum absorption coefficient are used like as informative parameters. The control is performed in spectral ranges in which the measured spectral radiation flux of the fire differs significantly from the filament lamp radiation. The informative parameters are interrelated, which should be taken into account when researching. Analytical dependences and initial data of the combined method for determining of the temperature and the spectral absorption coefficient are formulated. The accuracy at determining of the temperature and the spectral absorption coefficient by the combined method for the simulated and experimental spectrums of fires and filament lamps was researched. Combined method allows determining the temperature and spectral emissivity of the radiation source simultaneously. The error in calculation the temperature does not exceed 10%. The error in calculation radiation coefficient does not exceed 15%, which in is satisfactory. The further research is aimed at implementing the comprehensive method.
