Abstract

The embodiments of the invention disclose a method and a device for banknote thickness abnormality identification. The method comprises the following steps: detecting the thickness of a banknote through at least two thickness sensors, wherein each thickness sensor acquires a set of first thickness information corresponding to the target points of the banknote; calculating the average value of each set of first thickness information, and getting second thickness information corresponding to each thickness sensor; and if a first proportion of the thickness sensors of which the second thickness information is within a first thickness range is less than a first proportion threshold, judging that the thickness of the banknote is abnormal. By employing the technical scheme, under the premise of ensuring the speed of banknote thickness abnormality identification, the accuracy of banknote thickness abnormality identification is increased, the time consumed by artificial identification is reduced, and the identification rate of banknotes with abnormal thickness is increased.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of paper thickness detection, and in particular to a method and device for identifying abnormal thickness of banknotes. Background technique

[0002] Along with the quickening of people's life rhythm and the increase of currency cash circulation frequency, automatic teller machine has gradually become one of the most commonly used tools for depositing and withdrawing money.

[0003] During the circulation of banknotes, as the number of times of use increases, the banknotes will inevitably be damaged and incomplete. When the banknotes are damaged, people often use scotch tape to paste the damaged parts of the banknotes. For banks, when damaged banknotes appear, they need to be recovered in a timely manner. Therefore, in order to reduce the manpower and material resources required for identifying incomplete and damaged banknotes, a banknote verification module is usually installed in...
