the tower crane combination acquisition module is used for selecting from the tower crane information which can be connected in sequence from the conveying starting point to the conveying end point, selecting the tower crane combination comprising the tower cranes which are ordered in ascending order according to the size of the cargo transferring times and are ordered in front, and acquiring the tower crane combination.
5. The multi-tower crane transfer scheduling system of claim 4, further comprising a tower crane combination selection module configured to select a tower crane combination based on a preset condition of multi-tower crane transfer efficiency when the number of tower crane combinations obtained is greater than 1.
