A banknote magnetic signal detection method and device

Abstract

The embodiment of the invention discloses a banknote magnetic signal detection method and device, which can effectively solve the abnormal magnetic track phenomenon through the detection of the magnetic track and the repair of the abnormal magnetic track, and further greatly improve the identification accuracy and acceptance rate of the banknote identification device. The method of the embodiment of the present invention includes: S1: obtaining the original data of the banknote magnetic signal; S2: detecting the abnormal magnetic track on the original data to obtain the detection result; S3: if the detection result is an abnormal magnetic track, perform steps S4 and S5, otherwise Execute step S6; S4: repair the original data according to the preset repair rules to obtain repair data; S5: compare the repair data with the preset standard value to obtain the recognition result; S6: compare the original data with the preset standard Value comparison to get the recognition result.

Description

technical field [0001] The embodiment of the present invention relates to the field of banknote identification, in particular to a method and device for detecting magnetic signals of banknotes. Background technique [0002] Banknotes are closely related to people's lives. The appearance of counterfeit banknotes has seriously affected people's stable life, and sometimes even caused severe social problems. With the advancement and development of science and technology, banknote identification technology is also constantly innovating. Now the more commonly used banknote identification method is magnetic signal detection. [0003] The banknote identification device includes a banknote identification module, and the banknote identification module that uses the magnetic signal detection method to identify banknotes includes a magnetic identification module that detects the magnetic code of the security thread of the banknote. If the magnetic identification module is used for too ...

AI Technical Summary

Problems solved by technology

If the magnetic identification module is used for too long, it is very likely that the resistance-capacitance components on the head board will be aged, abnormal, or even damaged, which will cause the reference value of some magnetic channel signals to drift, which will lead to abnormalities in the detected magnetic signals. Abnormal track

[0004] In this case, the banknote recognition device follows the original recognition process, and banknote recognition errors will occur, which will affect the recognition accuracy of the banknote recognition module and the banknote acceptance rate of the banknote recognition device.
