1 results about "Horizontal migration" patented technology

This application relates to the field of industrial automatic control technology, and in particular to a method and system for correcting fabric deviation based on non-contact sensing data. The method includes: acquiring the deflection angle of the fabric on the first guide roller, the transmission line speed of the fabric production line, and the original edge deviation value of the fabric at the second guide roller; determining the lateral migration rate of the fabric using the deflection angle, transmission line speed, and a preset fabric slip coefficient; performing weighted integral processing based on the lateral migration rate to determine the expected coupling deviation value of the fabric's movement from the first guide roller to the second guide roller; determining the intrinsic deviation amount of the fabric using the expected coupling deviation value; and adjusting the angle of the second guide roller based on the intrinsic deviation amount. Through the above technical solution, more accurate correction control of fabric deviation can be achieved.
