Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] In the following description, for the purpose of illustration rather than limitation, explanatory schematic diagrams of many technical features are given for a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0031] In order to effectively solve the problem in the prior art that when the magnetic distance is greater than a certain threshold range, the magnetic data of the genuine banknote collected by the m...

Abstract

The invention belongs to the technical field of financial machines and tools, provides a magnetic amplitude compensation method and system and aims to problem that genuine notes are identified as counterfeit notes caused by the fact that magnetic data of the genuine notes collected by a magnetic sensor attenuate when magnetic interval is greater than a certain threshold range. The magnetic sensor collects magnetic amplitude of currently circulated notes, a magnetic interval detection device is added to measure the magnetic interval, and then the magnetic amplitude and measured corresponding magnetic interval are subjected to large-sample statistical analysis to acquire a relation model between magnetic attenuation amplitude and magnetic interval; in this way, magnetic amplitude data are compensated, or the magnetic interval is adjusted artificially in a targeted manner according to the relation model, and the problem of identifying the genuine notes as counterfeit notes in the prior art is solved efficiently.

Description

technical field [0001] The invention belongs to the technical field of financial equipment, and in particular relates to a magnetic amplitude compensation method and system. Background technique [0002] At present, when assemblers are assembling financial instruments such as banknote detectors and banknote counting machines with magnetic sensors that collect the magnetic amplitude of banknotes, the distance between the magnetic sensor that collects the magnetic amplitude of banknotes and the banknotes in the banknote inspection channel (i.e. the magnetic distance) ) is often judged by visual inspection, especially for novices, it is difficult to grasp the magnetic spacing; on the other hand, due to various reasons during the use of financial instruments, the magnetic spacing will also change. [0003] The inventor found that when the magnetic distance is greater than a certain threshold range due to any of the above reasons, the magnetic data of the real banknote collected ...
