It is paid attention to all the time that large rating power plants watch and control combustion situation and quantities the flame characteristic value in combustion field. Because of the complexity of combustion and restriction of measure means, so far it doesn't form means of combustion process control and quantity yet up till now by routine measurement method and diagnostic means.This thesis analyzes flame traits and distills flame characteristic values, and demonstrates the feasibility that measure temperature using the flame image;Proposed a method of combustion diagnosis based on wavelet Neural Network, combined digital image processing technology and DSP, then the evaluation of flame burning situation and flameout forewarning function are implemented.This thesis structures an embedded system for flame image acquisition and processing based on TMS320C6205 DSP. This system can overcome the shortage of the traditional image processing system based on PC mode, and improve its performance in the field of real time. The output control of image is implemented by SAA7111 and CPLD. DSP is used to realize varied image processing arithmetic and interface with computer through the PCI bus. The dissertation analyzes the design technique of each function module in details and the implementing of system software is discussed.At the end of this paper, it makes a summary and provides some further advice to the arithmetic and this system.
