High temperature furnace inner video image temperature measuring system

Abstract

The invention relates to a high temperature furnace in-furnace temperature measuring system, in particular to relating to a high temperature furnace in-furnace video image temperature measuring system which directly collects single frame image data from high temperature TV. The system comprises an industrial control host which is separately connected with the high temperature TV and CRT. The industrial control host also comprises three parts: a database, a human-computer interface and computational analysis. The high temperature TV adopts a probe-type high temperature TV. A video capture card is arranged on the industrial control host. The industrial control host makes use of control program to complete collecting high temperature furnace in-furnace video images, and processes to extract, analyze, process, compute and display for image data. High temperature furnace in-furnace video image temperature measuring result can guide operating personnel to keep high temperature furnace optimal thermal situation, so as to improve thermal efficiency, reduce pollutant formation, and improve labor and material processing quality. At the same time the high temperature furnace in-furnace video image temperature measuring result has very important effect for furnace flameout protection, avoiding furnace wall coking, refractory material shedding and processing fault diagnosis for the high temperature furnace.

Description

Technical field [0001] The present invention relates to a temperature monitoring system in a high-temperature furnace, in particular to a measurement based on the principle of thermal detection in the furnace using radiation image processing to extract, analyze, process, calculate, and display single-frame image data directly collected from a high-temperature television. Temperature system. Background technique [0002] The temperature measurement of the traditional high-temperature furnace monitoring system is based on the relationship between the physical and chemical properties of the substance and the temperature. For the temperature measurement of the working conditions in the high-temperature furnace, it is generally divided into contact measurement and non-contact measurement. Contact measurement will cause interference to the measured medium, and generally only point measurement can be achieved; non-contact temperature measurement has attracted much attention due to its a...

Problems solved by technology

At present, there are practical applications of high-temperature kiln temperature non-contact measuring instruments abroad, but the cost of the equipment is relatively expensive, and some products can only achieve single-point measurement

There are also researches and experiments in this area in China, but they are all in the initial and immature stage. In order to provide high-quality image monitoring and accurate temperature measurement for high-temperature furnaces, it is necessary to solve the problem of how to convert the image information in the high-temperature furnace into corresponding temperatures. a technical problem
