The invention discloses a rope-length-variable industrial travelling crane anti-swing control method based on seven-section trajectory planning. Aiming at the problem of anti-swing control of a variable-rope-length travelling crane in which horizontal movement and lifting movement of the travelling crane are coupled, the anti-swing control method of the variable-rope-length industrial travelling crane with seven-section trajectory planning is designed based on the idea of phase trajectory switching, so that the operation efficiency of the travelling crane is greatly improved; compared with traditional three-section type trajectory planning, the acceleration selectable domain of seven-section type trajectory planning is changed into a continuous domain from a discrete domain, the acceleration magnitude and the acceleration duration can be planned more flexibly, and the performance of a driving driver is brought into full play. A system hardware device of the seven-section type track planning industrial travelling crane anti-swing control method mainly comprises a PLC, a frequency converter, an alternating current asynchronous motor, an angle measuring instrument, a Gray bus distance measuring cable and an upper computer.
