Strip surface cleaning method and strip surface cleaning system based on real-time speed regulation

The invention discloses a strip surface cleaning method based on real-time speed regulation, and the method comprises the following steps: starting a high-pressure water jet strip surface cleaning device, shooting a strip at a feeding end through a visual device according to a preset time interval to obtain a group of strip surface image sets {Pn}, preprocessing the group of images to obtain an error e, discretizing e to a fuzzy domain, obtaining a fuzzy set description of e as input according to a preset membership function, and obtaining an actual value of the initial winding speed through fuzzy calculation; and the frequency converter is adjusted to enable the winding machine to convey the strip at the value. The corresponding strip surface cleaning system comprises a winding machine, a frequency converter, a visual inspection subsystem and a speed control subsystem. And the visual detection subsystem and the speed control subsystem are connected with the frequency converter. According to the method, the b
