Problems solved by technology

However, the disadvantage of wide-angle lenses is that there is a certain degree of surface imaging distortion, referred to as the fisheye effect
If the deformed picture is not corrected, it will directly affect the accuracy of extinguishing point monitoring

Abstract

The invention provides an intelligent layer-burning boiler extinguishing boundary detecting system. The system comprises a layer-burning boiler image collection subsystem, an extinguishing boundary calibration subsystem and an image processing subsystem. Firstly, according to the system, through a real-time video system with a set of refrigerating device, dynamic combustion image information of a layer-burning boiler is obtained; then through the extinguishing boundary calibration subsystem, image errors generated by an imaging system are eliminated and the fish eye effect of a wide angle video camera is calibrated; finally, through the view screen image processing subsystem, the accurate layer-burning boiler extinguishing boundary data can be obtained. The system is accurate in final extinguishing boundary data, simple in calibration principle and less in calculated amount, and the final extinguishing boundary data can also be published to the public according to the standard OPC protocol for development and application of a third party.

Description

technical field [0001] The invention relates to an intelligent detection system for the extinguishment limit of a floor-fired boiler. Background technique [0002] In recent years, with the development of my country's industrial and living standards and the continuous expansion of scale, the use of boilers has become more and more extensive. However, due to the dwindling raw material resources, its price is also increasing day by day. At the same time, my country's requirements for low-carbon environmental protection in industry and daily life are becoming more and more stringent. The most important thing is that a large part of the current boiler still relies on manual experience to monitor the control of combustion and fire extinguishing boundaries. If there is an error in the limit of combustion and fire extinguishing, if the fire is extinguished too early, there will be insufficient combustion and a waste of resources; if the fire is extinguished too late, the temperat...
