Utilize the color picture burnup decision control manner and the decision control unit

摘要

PURPOSE:To provide a combustion deciding method and deciding device which is devised to reduce a time delay to a value low enough to prevent a problem on a practicable use from arising. CONSTITUTION:A combustion state is photographed in a color image. A feature parameter determined from a chromaticity coordinate of a specified color specification widely related to a combustion state is inputted to a neutral network means 42 together with a process state amount, such as a combustion chamber outlet temperature T. From the image, adaptation to a typical combustion state is determined and the combustion state is evaluated.
