Banknote recognition module for deposit and withdrawal circulator

Abstract

The invention discloses a banknote recognition module for a deposit and withdrawal circulator. The banknote recognition module comprises an image acquisition transducer, a magnetic signal transducer and a thickness transducer which are sequentially arranged at intervals from a banknote inlet to a banknote outlet, and further comprises four photoelectric breakers and a main controller, wherein the four photoelectric breakers are pairwise arranged at internals in front of the image acquisition transducer and behind the thickness transducer, and the main controller is respectively communicated with the image acquisition transducer, the magnetic signal transducer, the thickness transducer and the photoelectric breakers. According to the banknote recognition module, inlet and outlet angles of each banknote are judged by the two pairs of photoelectric breakers, thereby effectively ensuring the effectiveness of middle number acquisition, magnetic strip acquisition and thickness acquisition and avoiding the generation of noise data; due to adoption of a Hall transducer, the judgment effect for stacking can be improved effectively, how many banknotes are stacked up can be judged, and moreover, a basis is provided for the subsequent banknote counting.

Description

technical field [0001] The invention relates to the technical field of financial equipment, in particular to a banknote identification module of a deposit and withdrawal recycling machine. Background technique [0002] The banknote identification module is the core module of the BV module in the deposit and withdrawal cycle equipment, which is used to identify and count. For the convenience of counting, the photoelectric sensor installed at a specific position in the banknote identification module is usually used to complete the banknote counting function. . However, in the actual process, due to holes in banknotes, adhesive tape or abnormal grinding of banknotes, etc., the counting of banknotes in the deposit and withdrawal cycle movement will be wrong. Moreover, in the process of depositing banknotes, there is a grinding failure or other special circumstances that cause banknotes to be doubled, which will also cause banknote counting errors.

AI Technical Summary

Problems solved by technology

In the actual process, due to holes in banknotes, sticky tape or abnormal grinding of banknotes, etc., the counting of banknotes in the deposit and withdrawal cycle movement will be wrong.

Moreover, in the process of depositing banknotes, there is a grinding failure or other special circumstances that cause banknotes to be doubled, which will also cause banknote counting errors. There has been no good solution, which greatly affects the reliability and stability of the deposit and withdrawal cycle movement. , how to improve the measurement accuracy and data diversity of the banknote recognition module has become an urgent problem to be solved
