Embodiment Construction

[0087] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0088] like figure 1 As shown, a method for automatically checking the fire of an aluminum electrolytic cell provided in an embodiment of the present invention includes:

[0089] Step 1: Obtain the fire eye image of the aluminum electrolytic cell, and convert the fire eye image into a fire eye digital image through a converter.

[0090] like figure 2 As shown, in this embodiment, the image of the fire eye of the aluminum electrolytic cell is collected by the image acquisition sensor.

[0091] Step 2: Preprocess the Huoyan digital image, including noise reduction and smoothing.

[0092] Specifically, the image is cleaned to eliminate the influence of sampling noise.

[0093] Step 3: Convert the Huoyan digital image preprocessed in step 2 into a Huoyan grayscale image, and construct a grayscale image matrix;

[0094] Each element in the gra...

Abstract

The invention discloses a method and device for automatically observing fire in an aluminum electrolytic cell. The method comprises the steps of (1) obtaining a fire eye image of the aluminum electrolytic cell and converting the fire eye image into a fire eye digital image, (2) preprocessing the fire eye digital image, (3) converting the preprocessed fire eye digital image into a fire eye gray image and constructing a gray image matrix, (4) using a multiple-threshold cutting method of a gray value to carry out function area division on the fire eye gray image according to the gray image matrix in the step (3), (5) extracting a fire eye information index of the function area in the step (4), wherein the fire eye information index is at least one item in area, temperature and a texture feature value, and (6) displaying the fire eye image and fire eye information to realize automatic fire observation. Through the above method, the fire eye image can be obtained, a fire eye appearance condition and hidden information can be rapidly and accurately obtained, and the automatic fire observation function of the aluminum electrolytic cell is realized.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolysis, and in particular relates to a method and a device for automatically checking the fire of an aluminum electrolytic cell. Background technique [0002] The modern aluminum electrolytic cell is an electrochemical reactor with self-recovery, which requires both feeding and discharging (aluminum output). The electrolytic cell cannot be overcooled or overheated, and its state is crucial to energy consumption and production stability. important. Modern aluminum electrolysis adopts the point-type feeding method. After the shelling hammer falls, the point-type feeding device discharges the material, and the crust opened by the hammer will form a hole. In addition to the molten electrolyte, there is also a hole in the hole. There is a flame formed by the combustion of the anode gas and the combustion point of the carbon slag in the dielectric, which in turn forms a fire-like hole, which is ...
