The present invention relates to the technical field of
aluminum electrolysis parameter measurement. Disclosed is a two-level and
cathode voltage drop calculation method for an
aluminum electrolysis cell.
Voltage signal data and displacement
signal data are collected and stored in arrays; the data is preprocessed; a trigger condition for an air and
electrolyte interface and a trigger condition for an
electrolyte and aluminum
liquid interface are set; for each group of data in the arrays, an
electrolyte level and an aluminum level are calculated and rationality determination is performed; and average values are taken as final values. The present invention achieves unmanned measurement of process parameters such as
aluminum electrolysis cell electrolyte and aluminum liquid heights and
cathode voltage drop, thereby improving the
automation and intelligence level of the
electrolysis process, reducing the risks and costs of manual measurement, and improving testing efficiency and accuracy.
