[0013] The purpose of the present invention is aimed at the above-mentioned monitoring system for the molten steel surface in the furnace of the secondary refining molten steel using a display. When acquiring images, the existing products only have the automatic aperture to adjust the brightness of the entire image, so that the prospect of the molten steel can be observed. The brightness control of the image is not sensitive, and sometimes it will cause the molten steel image to be too bright and saturated, and the image monitoring function cannot be used. It provides further processing of the image that can be seen by using electronic technology; it specifically extracts part of the image signal for the image that cannot be used. Automatically adjust the aperture, so that when the entire image is unusable, it can be used normally after being automatically processed by the image electronic optimization device

The invention discloses a furnace steel water surface monitoring system and its image optimization device. The image optimization device obtains an input image from a CCD camera of the furnace steel water surface monitoring system, optimizes the image and outputs it to the furnace steel water surface monitoring system. monitor, and output feedback signals to control the automatic aperture lens of the furnace steel water surface monitoring system. The image optimization device extracts the image of the molten steel surface part and automatically adjusts the automatic aperture lens to ensure the visibility of the image of the molten steel surface part. The image optimization The device includes: an input device, a molten steel image detection device, a central processing unit, an image enhancement device, and an output device. The image optimization device of the present invention can automatically adjust only the bright signal of the molten steel object to be observed, and the active adjustment ability of the aperture and the sensitivity response ability to the brightness of the molten steel are greatly improved, so that the brightness of the molten steel image can be adjusted all the time In the range where the human eye can observe the image, the display is in the best working condition.
Description
technical field [0001] The invention relates to the field of automatic instruments, more specifically, to a furnace steel water surface monitoring system and an image optimization device thereof. Background technique [0002] The RH furnace (Ruhstahl-Hausen vacuum degassing process, RH) used in steelmaking has the function of vacuum circulation degassing, and is a secondary refining equipment widely used in smelting high-grade steel. It is used to adjust the composition and temperature of molten steel and remove carbon, gas and oxygen from molten steel during the circulation of molten steel. During the feeding process of molten steel composition adjustment and molten steel circulation degassing operation, it is necessary for the operator to carry out real-time observation and strict monitoring of the images of these two key processes. Refer to figure 1 as shown, figure 1 It is a schematic diagram of the installation of the steel water surface monitoring system of the steel...
