Accurate stop and automatic reversing control system of high-speed precise strip steel cold-rolling mill

The invention relates to the field of strip steel rolling, and discloses an accurate stop and automatic reversing control system of a high-speed precise strip steel cold-rolling mill, which comprises a strip steel ring number metering system, a strip steel coil diameter metering system and a pass process treatment system, according to the system, the number of strip steel rings on the outlet side of an upper pass and the strip steel coil diameter on the inlet side of the pass serve as important bases for uncoiling and accurate stopping of the pass, and the distance between a parking mark of the pass and a roller gap and the distance between adjacent parking marks on the same side are all about 0.1 m by controlling the number of the rings. And after rolling of the pass is completed, the pass process processing system automatically reads preset process data of the next pass in the rolling process table and issues the process data to the corresponding single machines to achieve automatic reversing.
