AI Technical Summary

Technical Problem

Existing incinerator combustion status monitoring technologies cannot simultaneously meet the requirements of intuitiveness and real-time automatic control. Pure data monitoring lacks information on flame location, leading to insufficient adjustment, while manual observation is not real-time and consumes a lot of manpower.

Method used

By continuously acquiring images of flame combustion in the incinerator, calculating the number of pixel changes between adjacent frames, capturing the current frame image when a preset threshold is reached, and comparing and analyzing it with pre-stored images of good flame combustion, a flame adjustment signal is generated to drive the actuator to adjust the combustion state, and closed-loop control is achieved in conjunction with the central control system.

Benefits of technology

It enables low-cost, fully automatic or semi-automatic real-time combustion state adjustment, improves the stability and automation level of incinerator combustion, and avoids data lag and the inadequacy of manual observation.

Abstract

The present application relates to waste incineration technical field, specifically to a kind of incinerator combustion state monitoring method and system, comprising: the flame combustion image in the continuous acquisition incinerator, obtain flame combustion image sequence;The pixel change quantity between adjacent two frames of flame combustion image is calculated, when pixel change quantity reaches preset pixel change threshold, capture current frame flame combustion image;Current frame flame combustion image and the flame position coordinates of pre-stored flame combustion good image are compared and analyzed, generate flame adjustment signal;According to flame adjustment signal, drive actuator to adjust the flame combustion state in incinerator.The present application is by collecting flame image, only when pixel change reaches threshold triggers analysis, comparison good image generates adjustment signal automatic adjustment, realize intuitive real-time low-cost closed-loop control, overcome data not intuitive, artificial lag defect, improve incineration stability and automation.
