Abstract
A banknote temporary storage module is provided, including large and small reels driven by first and second power motors respectively, a coiling tape, first and second coded discs, first and second sensors and a microcontroller. The first and second coded discs are fixed on rotating shafts of the large and small reels respectively. The first and second sensors are arranged corresponding to the first and second coded discs respectively and are used for monitoring rotating angles of the large and small reels respectively. The microcontroller is used for calculating the length of the coil tape released by the small reel each time the large reel rotates for one circle, and calculating the current radius of the large reel, and thus angular velocities of the large and small reels are controlled to make the linear velocity of the large reel consistent with that of the small reel.
