[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 water-level monitoring system and an image optimizer thereof. The image optimizer acquires an input image from a CCD camera from the furnace water-level monitoring system, optimizes the image and then outputs the optimized image to a monitor of the furnace water-level monitoring system, and outputs a feedback signal to control an automatic aperture lens of the furnace water-level monitoring system. The image optimizer extracts the image of the molten steel level and correspondingly adjusts the automatic aperture lens to ensure the visibility of the image of molten steel level. The image optimizer comprises an input device, a molten steel image detector, a central processing unit, an image intensifier, and an output device. The inventive image optimizer has automatic adjustment function only related to the brightness signal of molten steel target to be observed, and can greatly improve the automatic adjustment ability of the aperture and the sensitive response ability to the brightness of molten steel, so that the brightness of molten steel image is controlled within the visibly observable range and the display is ensured in optimum working state.
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...
