Problems solved by technology

At present, full radiation pyrometers or colorimetric pyrometers are used to detect the temperature in the high-temperature furnace, but this method can only detect the temperature of one point at a time, and the full radiation pyrometer or colorimetric pyrometer needs to be moved during the detection process. It is very inconvenient to detect different areas
In recent years, with the development of electronic technology and the maturity and popularization of camera technology, infrared thermal imaging cameras have been used to detect the temperature distribution of furnace temperature. However, due to the high cost of infrared thermal imaging cameras, and their best working spectrum is Measurement of medium and low temperature, and not suitable for working in harsh environments such as high temperature

Embodiment Construction

[0025] See figure 1 and figure 2 , the device includes a heat-insulating and concentrating optical element 1 , an optical fiber array 2 , and a color image sensor 3 arranged in sequence. The above-mentioned concentrating optical element 1 is a focusing objective lens with a convex side and a flat surface. The focusing objective lens is installed at the front end of the detection device casing. The focusing objective lens collects images of high-temperature temperature fields through the heat-insulating glass 11 on the wall of the high-temperature fire site; the above-mentioned optical fiber array 2 The optical fiber array composed of G.651 bare optical fiber without protective sleeve is used. The optical fiber array 2 is neatly arranged into a circular array by more than 30,000 multimode bare optical fibers L2; ​​the above-mentioned color image sensor 3 is a CCD digital camera with adjustable focus, which can be used 1 / 3 inch CCD computer camera PC2032, the output of the cam...

Abstract

The invention discloses a high temperature field and fire image detecting device and detecting method that could supply high temperature field image in time by adopting mixing image receiving fiber array and computer temperature field video processing, and testing the temperature any points in the temperature field by color comparison temperature measuring technology. Taking temperature field interpolation process by computer, it could accurately calculate the other points in the high temperature field. The invention has wide application field.

Description

technical field [0001] The invention relates to a device for detecting a high-temperature temperature field and a flame image and a detection method thereof. Background technique [0002] With the continuous progress of metallurgical technology, the measurement and control of temperature in metallurgical technology is becoming more and more important. At present, in some large and medium-sized enterprises, color industrial cameras or industrial TVs are mainly used to monitor the flame images of high-temperature furnaces, and inspectors judge the temperature in the high-temperature furnaces based on the observed flame images and actual experience. This detection method, which relies on manual observation and judgment based on experience, has poor accuracy. In addition, Chinese patent 94111569.0 discloses a "power plant boiler furnace combustion distribution detection method and its device". This method is based on the power plant boiler furnace flame TV monitoring device, an...
