Embodiment Construction

[0031] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings, and the superheat state of the aluminum electrolytic cell is divided into three categories: large, normal, and small according to the actual operating conditions.

[0032] 1. Video capture module

[0033] From an aluminum electrolysis factory, a hand-held industrial camera was used to shoot 22 videos of different superheating states. The size of each frame of the video is 1920*1080, and the average duration of each group of videos is 80s, and then the collected videos are saved to the image acquisition stuck.

[0034] 2. Data processing module

[0035] Read the collected video data from the image acquisition card, decompose the read video data into multiple frames of RGB images, select the red channel in each frame of RGB images, and perform threshold segmentation on the red channel. The threshold value is 230, and after segmentation The binarize...

Description

technical field [0001] The invention relates to a method and system for identifying the superheat state of an aluminum electrolytic cell based on a 3D convolutional neural network, which can be applied to the identification of the superheat state in the production process of aluminum electrolysis, and belongs to the technical field of aluminum electrolysis. Background technique [0002] After decades of development, the aluminum electrolysis industry has gradually become an important basic industry in my country. However, due to the high power consumption in the production process, it has become one of the key industries regulated by the state. The degree of superheat (the difference between the electrolyte temperature and the primary crystal temperature) can well reflect the state of the aluminum electrolytic cell. Specifically, when the degree of superheat is high, the current efficiency is low, otherwise the current efficiency is high. Therefore, many experts have studied ...
