A method for controlling the retort of brewing and distillation process by using images

Abstract

The invention discloses a method for controlling material distilling in liquor brewing distillation technology by use of images. The method comprises steps of step 1, initializing a system; step 2, image acquiring: acquiring infrared thermal images; step 3, carrying out circulation test on the infrared thermal images; step 4, extracting pixel regions meeting the condition that the pixel value G is between G1 and G2 in the infrared thermal images as heat regions; step 5, processing the heat region images; and step 6, solving the position of the center point of covering materials, and charging materials in the center point to the boundary position of a covering material region, thereby finishing material charging. According to the invention, a thermal imaging camera is used for acquiring images so as to search the heat regions, so the position of an overflow critical point of the liquor steam is intelligently recognized; the coordinate of the center of mass is solved, so the material distribution center is rapidly determined in real time and through a hopper, tracking is automatically performed and specific spiral type material distribution to the boundary of the covering material region is performed; and efficiency of material distilling and yield of liquor during a distillation process are greatly improved.

Description

technical field [0001] The invention relates to a method for controlling retorts in a brewing distillation process by using images, and belongs to the technical field of automatic control. Background technique [0002] In the brewing process, in order to ensure the alcohol content, it is generally necessary to carry out distillation and purification. It is inevitable that the staff will make mistakes or fail to operate in time when loading the retort. If the wine vapor overflows, it will affect the yield and quality of the wine. Increase the cost of wine making. [0003] Although some enterprises have adopted partial automation and mechanization devices, continuous mechanization has not been realized, and some major technical difficulties have not been overcome or the effect is not satisfactory. In terms of machine vision, the retort bucket is first divided into multiple areas of equal area, and the infrared camera is used to scan and compare the gray value to find the stea...
