The application relates to the technical field of interface measurement, and discloses an electrolytic aluminum
electrolyte aluminum
liquid interface measurement
system based on conductive characteristics, which comprises a
data acquisition module that obtains
impedance distribution data at different depth positions by controlling a probe to move in a vertical direction and collecting impedance signals; the
data acquisition module adopts a multi-frequency excitation mode to obtain impedance responses at different frequencies during the movement of the probe, and adaptively adjusts the movement speed of the sampling probe according to the stability of the collected signals; an impedance change rate is extracted according to the
impedance distribution data, the interface is judged based on the impedance change rate, and a candidate interface of the electrolytic aluminum
electrolyte aluminum liquid is determined; one candidate interface of the electrolytic aluminum
electrolyte aluminum liquid is selected, random multi-point measurement is carried out in the horizontal direction of the candidate interface, measurement information in the horizontal direction of the candidate interface is collected, and an evaluation model is constructed; and the application helps to improve the recognition accuracy of the interface.
