Design and Realization of a Pipe-tracking Algorithm for Ultrasonic Detection

Addressing the problems staying with the detection line like abnormal sorting and missing of hole type defects as caused by error signal sent from the pipe gap sensor, the two-stage pipe-tracking control algorithm is developed, and then its suitability is analyzed via relevant on-the-site serial tests. It is regarded via the analysis that the newly-developed pipe-tracking algorithm seems to be mostly suitable for the specified-pipe detection line;it s necessary to achieve the optical pipe-tracking speed ratio via theoretic calculation and on-the-site testing so as to ensure proper position tracking;if each single driving roller is controlled independently, the pipe tracking requirement for pipes with different lengths can be met by means of adjusting the primary pipe-tracking position.
