Paper money safety line detection method and device

Abstract

The invention provides a paper money safety line detection device, which comprises a magnetic detection mechanism and a control mechanism, wherein the magnetic detection mechanism comprises a magnetic head component, a magnetic head is arranged in the magnetic head component and the magnetic head is movably arranged along a direction in parallel with the extension direction of a paper money safety line; and the control mechanism is connected with the magnetic detection mechanism and is used for controlling the magnetic head to move along the extension direction of the paper money safety line when the safety line of paper money is aligned to the magnetic head, reading magnetic data and judging the authenticity of paper money according to the read magnetic data. The invention additionally provides a paper money safety line detection method, which comprises the steps of: when the safety line of the paper money is aligned to the magnetic head, controlling the magnetic head to move along the extension direction of the paper money safety line to read the magnetic data; and judging the authenticity of the paper money according to the read magnetic data. The device and the method providedby the invention have the advantages that the narrow-breadth magnetic head is only required and can move along the direction of the paper money safety line to read the magnetic data and the reductionof equipment cost is facilitated.

Description

technical field [0001] The invention relates to a banknote anti-counterfeiting device, and more particularly, to a banknote security line detection method and device. Background technique [0002] The commonly used fifth edition RMB authenticity detection device is to place banknotes horizontally in the banknote detection device, and the magnetic security line of the banknotes is in the same direction as the banknotes are transported, such as figure 1 As shown, the corresponding banknote security thread detection method is as follows: banknotes are placed horizontally, and the conveying mechanism 2' transports the banknotes. When the banknotes pass through the magnetic head 3', the security thread passes through the magnetic head 3' from the beginning to the end, thereby generating a series of magnetic signals, thus, The magnetic head 3' can detect the magnetic security on the banknote from beginning to end, quantitatively interpret the magnetic data in the magnetic security...
