The invention relates to the field of roller ways for hot rolled slabs, in particular to an anti-collision control method of a conveying roller way. The intelligent anti-collision control method of the roller way frame comprises the following steps that S1, a plurality of conveying rollers are arranged on the roller way frame at equal intervals, a plurality of lifting mechanisms are arranged belowthe roller way frame, and the lifting mechanisms are lifted under the control of an anti-collision controller to enable the roller way frame to change the position state; S2, the anti-collision controller obtains the bending-down amount, the speed and the position of a bending-down part; and S3, when the bending-down part of a supplied material plate blank arrives at a certain conveying roller, the anti-collision controller controls the lifting mechanisms to drive the roller way frame to change the position state according to the bending-down amount, so that the conveying roller is enabled toavoid the bending-down part of the supplied material plate blank, and the roller way frame is driven to be reset by the lifting mechanisms until the bending-down part passes through the last conveying roller of the roller way frame. According to the method, the roller way frame is driven to avoid according to the degree of the bending-down part, so that collision is avoided, the service life of the roller way frame is prolonged, the time and the cost required by equipment maintenance are reduced, and the production efficiency is improved.
