by adopting the invention, the accuracy of the steel coil library map of the steel unmanned overhead travelling crane library area is improved from the original 97.1% to the current 99.3%, thereby indirectly reducing the occurrence of the events of library area roll smashing, roll turning and the like and reducing the occurrence of unqualified products.
The safety factor of the reservoir area is improved, a large amount of manpower is saved, and the method is embodied as follows:
the frequency of entering an unmanned overhead traveling crane operation area by workers is reduced, the operation process is changed from the original operation of completing the inventory of the area once (about 2 hours) in the next shift, the inventory is purposefully performed according to the system prompt, the average inventory working time is reduced to 40 minutes, so that the inventory personnel in each shift can be combined with the ground personnel who rolls off the line in the pickling process, and one worker can be reduced in each shift.
