Case 1: a certain SY500 electrolysis series adopts an aluminum alloy cylinder, a magnetic strip is arranged in the cylinder, 10 sensor arrays are arranged outside the cylinder, and the sensors adopt one-way magnetic induction elements (which induce along the radial direction of the cylinder) but form a cluster. The sensor signal is connected to the intelligent control box through a cable. Crust breaking and blanking signals of the electrolytic cell crust breaking and blanking control box are introduced into the intelligent control box for comprehensive judgment. In the crust breaking process, if the main sensor in the sensor array is not detected, the intelligent control box sends a delayed pressurizing crust breaking command to the cylinder and continuously pressurizes crust breaking for many times. If the relevant signals are not detected, the corresponding points stop blanking, and other groups of blanking are changed, so that the problem of groove material blockage is solved.
