Description
Technical field:
The present invention relates to image monitoring device, more specifically say so and a kind ofly carry out real-time device for monitoring for heated parts operating condition and temperature regime thereof in the stove under the hot environment.
Background technology:
Each class A furnace A of metallurgy and chemical industry, pyrolysis furnace, olefins furnace etc. all are the visual plants of production run, the heating and temperature control of material (heating member) is directly connected to yield rate and product quality, what the temperature detection of the inner heating member of traditional high-temperature burner hearth adopted mostly is hyperthermia radiation meter or double-colored thermo detector etc., and there is following problem in these class methods:
1, surveyed area is very limited;
2, can only be " fanning out from point to area ", can't realize comprehensive temperature detection of heating member;
3, owing to the restriction of factors such as cost and installation site, the employing quantity of this type of thermo detector is (1～2 cover/stove) too much, so the parameter amount that provides is limited, is difficult to obtain to describe the hot physical index of actual demand.
Though 4, the method can detect extremely limited local temperature, can't carry out Direct observation.If will realize that Real Time Observation also need install utiliscope additional.
Summary of the invention:
Technical matters to be solved by this invention is to avoid above-mentioned existing in prior technology weak point, and a kind of image temperature measuring equipment based on colored and Near-infrared Double CCD that can carry out comprehensive temperature monitoring to heating member is provided.
Design feature of the present invention is to adopt double light path high temperature optical lens and two ccd video cameras have the high temperature sheath to form high temperature images probe, and one of described two ccd video camera are the high-temperature color ccd video camera, another is high temperature Near Infrared CCD video camera; This high temperature image probe is fixedly mounted on the shooting hole that is opened in the furnace wall by the fixed support that is arranged in the outside, furnace wall, inserts in the furnace wall by the double light path high temperature optical lens of high temperature sheath protection.
The present invention adopts the colorimetric high temperature tv system of two CCD methods, and reliably and comprehensively temperature survey can be provided at the intended target of video image, provides reliable foundation for burning, reach the technology adjustment, and compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is a kind of real-time monitoring device of target temperature on a large scale that is applicable under the furnace high-temperature environment, by adopting two CCD detection techniques, can realize burner hearth inside operating mode is monitored, temperature of heating member is carried out multi-functionals such as comprehensive monitoring, expand the range of application and the function of industrial television greatly.
2, the present invention can provide reliable at the intended target of video image and comprehensively temperature survey, obtain to describe the hot physical index of actual demand, ensure that to realizing combustion optimisation, the large-scale combustion apparatus security of raising, economy, yield rate, product quality and heat processing technique very important meaning is all arranged.
3, only need configuration 1～2 cover the present invention can realize the complete detection of full burner hearth target temperature.
4, the present invention has more practical significance with respect to full fire box temperature field detection method and wants economical a lot.
The drawing explanation:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the two CCD sonde configuration synoptic diagram of double light path of the present invention.
Fig. 3 is a mounting means synoptic diagram of the present invention.
Referring to Fig. 2, present embodiment adopts the double light path high temperature optical lens 2 have high temperature sheath 1 and two ccd video cameras to form that in 5, two ccd video cameras of high temperature images probe one be a high-temperature color ccd video camera 3, another is high temperature Near Infrared CCD video camera 4.
Referring to Fig. 1 and Fig. 3; high temperature image probe 5 is fixedly mounted on the shooting hole 7 that is opened in the furnace wall by the fixed support 6 that is arranged in the outside, furnace wall; double light path high temperature optical lens 2 by 1 protection of high temperature sheath is inserted in furnace wall 9; and aim at the workpiece target of required detection, its front end is advisable with the madial wall that does not protrude from furnace wall 9.
Fig. 1 illustrates, micro computer image and data processing equipment 8 are set, and the output signal of high temperature image probe 5 inputs in this treating apparatus 8.In concrete the enforcement, high-temperature color ccd video camera 3 and high temperature Near Infrared CCD video camera 4 will be imaged on respectively from the same width of cloth target image of double light path high temperature optical lens 2 on separately the target surface, and its output signal inputs to jointly with in set of diagrams picture and the data processing equipment 8.
By the high temperature image probe 5 two-path video picture signals of obtaining (colour and near-infrared image signal) in this micro computer image and data processing equipment 8 through gather the analysis of laggard circumstances in which people get things ready for a trip degree, the gamma correction scheduling algorithm is handled, obtain the comprehensive temperature information of heating member target, export to combustion control system by special purpose interface.On display, show video image or the target temperature profiles image that obtains simultaneously.
Referring to Fig. 3, in concrete the enforcement, high temperature sheath 1 is the coaxial cylindrical sleeve that is arranged on the front opening of double light path optical lens 2 peripheries, leads to gas channel stove in this cylindrical sleeve for it from desired gas in the stove of source of the gas, realizes air-cooled.Cylindrical sleeve as high temperature sheath 1 can be that individual layer also can be a multilayer.For sandwich construction, within it in the layer, and its layer with layer between all form the gas channel of desired gas in the stove.In gas circuit, answer pressure sensor, in order to detect the guarantee situation of heat eliminating medium.
When hanging down the precision monitoring, can utilize the near infrared induction directly to analyze and determine, realize high speed processing;
When carrying out system calibrating and high precision monitor, can utilize the infrared light of Near Infrared CCD induction and the ruddiness of colored CCD induction to carry out colorimetric measurement.
The present invention can be widely used on all types of industries stoves such as the various annealing furnaces of industries such as metallurgy, chemical industry, building materials, heating furnace, tempering furnace, pyrolysis furnace, olefins furnace, rotary kiln.
