ICP light source flame state detection device and detection method

Abstract

The invention provides an ICP (Inductively Coupled Plasm) light source flame state detection device and a detection method. The detection method comprises the steps: incident flame light of an ICP light source is attenuated by a light attenuation filter; the attenuated flame light is transmitted to an image sensor; after the attenuated flame light is sensed by the image sensor, a flame image is obtained; the flame image is transmitted to a video frame buffer; the frequency of the flame image is adjusted by the video frame buffer, so the frequency is consistent to the frequency of a processor, accordingly, information of each frame of flame image collected by the image sensor is obtained, and image obtainment is finished; then, the image information is transmitted to the processor, and the image information is subjected to image pretreatment, mode matching and flame state judgment by the processor. The device and the method overcome the defects in the prior art, the detection and analysis can be carried out on the ICP light source flame state, and reliable detection results can be provided for subsequent fully-automatic ignition control of instruments.

Description

Technical field [0001] The invention relates to an ICP light source flame state detection device and a detection method. Specifically, the pattern matching is performed by collecting the image information of the ICP flame and extracting the characteristic quantity of the flame, and finally judges by the characteristic quantity of the successfully matched flame. Design method of flame state. Background technique [0002] In the process of using the existing inductively coupled plasma light source, sometimes the flame is unstable, the flame is extinguished, and the ignition is difficult or even impossible. During the ignition process of ICP light source, the flame state will mainly appear in the following situations: when only the igniter is turned on, there is only a jumping arc in the moment tube; when the output power is increased to 200W, the arc-like light in the moment tube becomes stronger and jumps. When the power is increased to 800W, if the matching effect is good, the v...

Problems solved by technology

Based on different perspectives, the method of judging the flame state from the change of the overall characteristic quantity of the flame has also been developed. Many scholars at home and abroad have done a lot of research on the flame combustion diagnosis based on digital image processing, mainly focusing on these Aspects: It is applied to the diagnosis and detection of flame combustion in boilers of generator sets, the diagnosis and detection of combustion flames, the identification and early warning of fire hazards, etc., and there are few studies on the combustion state of flames suitable for ICP light sources
