Molten aluminum and electrolyte level measurement system in production of electrolytic aluminum based on machine vision

Abstract

The invention discloses a molten aluminum and electrolyte level measurement system in the production of electrolytic aluminum based on machine vision. The system comprises an AGV routing inspection trolley system; a measurement drill rod system is arranged at the upper part of the AGV routing inspection trolley system, and a machine vision detection system is arranged at the lower part of the AGVrouting inspection trolley system; the measurement drill rod system comprises a measurement drill rod arranged aslant, the bottom of the measurement drill rod is positioned in electrolyte, and the topof the measurement drill rod is positioned on the AGV routing inspection trolley system; the machine vision detection system adopts a monocular fixed-focus camera and the measurement drill rod positioned in a fixed field depth plane as a recognition target and a size reference target. The equipment can automatic stand at the right position and recognize an aluminum hole; the measurement drill rodcan be inserted automatically; and machine vision measurement and data generation and transmission can be automatically performed. According to the equipment, the labor intensity of workers can be relieved, the labor productivity can be improved, the real-time data transmission and data analysis and utilization are facilitated, and the significance is provided for intelligence and automation of the electrolytic aluminum industry.

Description

technical field [0001] The invention relates to the detection, image processing and visual measurement of liquid aluminum and electrolyte levels in the production process of electrolytic aluminum, and automatically measures the liquid aluminum and electrolyte levels by means of visual system calibration, image preprocessing, image recognition and image ranging. The invention belongs to the technical field of electrolytic aluminum production industry. Background technique [0002] In the electrolytic aluminum production process, the aluminum level and the electrolyte level are two important parameters for the production management of the electrolytic cell. The main function of the electrolyte is to conduct electricity, dissolve alumina and separate the anode reaction and cathode reaction. The level of electrolyte is directly related to the ability to dissolve alumina, and also affects the mass transfer inside the electrolyte and the uniformity of alumina dissolution. And the ...
