The modern method for aluminum production is electrolysis, which extracts molten aluminum from a mixture of cryolite and alumina. During the aluminum electrolysis process, due to density differences, the molten aluminum settles at the bottom while the electrolyte remains on top. The balance of the heights of the molten aluminum and the electrolyte directly affects the current efficiency during aluminum production. Given the enormous current involved in the electrolysis process, even a slight reduction in current efficiency can lead to significant energy wastage. Therefore, maintaining the balance between the molten aluminum and the electrolyte requires regular measurements to adjust feeding strategies. However, the current measurement method is manual, time-consuming, labor-intensive, and cannot provide real-time height data. This paper addresses the issue of strong interference in the measurement of key parameters in aluminum electrolysis production and presents the design and implementation of an embedded electronic system based on an ARM processor. The system is designed to interface with sensors and various peripheral devices. Through manual and automatic control, multiple parameters within the electrolytic cell could be measured and displayed in real time. Field test results indicated that this system effectively obtained precise data on the aluminum electrolysis production process, potentially becoming a fundamental component for the intelligentization of aluminum production in the future.
