Converter tapping ladle liquid level identification method and system, medium and terminal

Abstract

The invention provides a converter tapping steel ladle liquid level identification method and system, a medium and a terminal. The method comprises the steps: obtaining the image information of the liquid level of converter tapping molten steel; performing image processing on the image information to obtain a plurality of edge contours; connecting the edge contours through dilation operation; restoring the image obtained after edge contour connection through erosion operation, and obtaining the position of the molten steel liquid level; recognizing the restored image, and deleting contour points in a steel flow area if the steel flow exists in the molten steel liquid level image; performing ellipse fitting on the contour of the contour point in the deleted steel flow area to obtain a fitting result, and taking the fitting result as a molten steel liquid level contour. According to the method, the position information of the steel ladle in the image can be effectively identified, the height of the liquid level of the molten steel in the buggy ladle below the converter can be monitored in real time, whether converter tapping needs to be finished or not is judged, manual participation in the steel ladle identification process is avoided, and the production efficiency and safety are improved.

Description

technical field [0001] The invention relates to the field of iron and steel smelting and image processing, and in particular to a method, system, medium and terminal for identifying the liquid level of a converter tapping ladle. Background technique [0002] During the process of tapping from the converter, the height of the liquid steel level in the ladle is an important parameter for judging whether tapping is over. If the tapping is not completed in time before the molten steel fills the ladle car under the furnace, it will cause the molten steel in the converter to leak, destroy the field equipment, affect the production efficiency, and even cause safety accidents. [0003] At present, in the traditional converter tapping system, the on-site workers usually wear protective glasses and poke their heads out from the window of the control room next to the converter to visually measure the liquid level in the ladle car under the furnace. When the molten steel level is close...

Problems solved by technology

However, this method cannot meet the needs of intelligence. Therefore, a new method for identifying the liquid level of the converter tapping ladle is urgently needed to effectively identify the position information of the ladle in the image and to monitor the molten steel level in the ladle car under the furnace in real time. The height is used to judge whether to end the converter tapping and avoid manual participation in the process of identifying the ladle
