Thickness identification device of slice-type medium and identification method thereof

Abstract

The invention relates to the field of medium thickness detection, in particular to a thickness identification device of a slice-type medium and an identification method thereof. By means of the provided thickness identification device of the slice-type medium, the problem of low measurement reliability of the existing thickness identification device of the slice-type medium is solved. The thickness identification device of the slice-type medium comprises a thickness measurement module, a data storage module, a data correction module and an identification module, wherein, the thickness measurement module acquires the thickness measurement information of the slice-type medium; the data storage module stores standard thickness data and reference nominal data of measured data; the data correction module carries out data correction on the thickness measurement information acquired by the thickness measurement module according to the reference nominal data so as to obtain thickness detection data of the slice-type medium; and the identification module compares the thickness detection data with the standard thickness data so as to complete thickness identification of the slice-type medium. In the invention, by correcting the measurement information, measurement errors are reduced, the identification accuracy of financial service equipment is improved, and identification robustness of negotiable documents is enhanced.

Description

technical field [0001] The invention relates to the field of medium thickness detection, in particular to a device and a method for discriminating the thickness of a sheet medium. Background technique [0002] In the process of authenticating banknotes in existing financial service equipment, the thickness of banknotes is an indispensable means of identification. At present, sheet-type valuable documents are generally made of special materials into sheet-shaped media with certain thickness characteristics. Currently, counterfeit valuable documents and spliced ​​valuable documents are trying to forge this thickness identification feature to deceive ordinary financial institutions. The detection of this identification feature by the device. Therefore, in financial service equipment, reliable identification of the thickness of the value document is of great significance to the authenticity of the value document. In addition, the detection of the thickness of sheet media is an...

Problems solved by technology

[0007] (2) Due to problems such as material life or use loss, the surface of the reference roller is worn, causing the detection contact surface of the reference roller to be not smooth. Then, the closed curve formed by the reference roller after one rotation is not an ideal, standard circle, and the closed curve is different. Points have unequal radii

[0008] (3) Due to problems such as material life or wear and tear, the surface of the detection roller is worn, resulting in the detection contact surface of the detection roller being not smooth; the closed curve formed by the detection roller rotating one circle is not an ideal, standard circle, and the points of the closed curve unequal radii

[0010] Due to the above-mentioned problems in the thickness measurement module, for financial service equipment that uses the thickness measurement module as the basis for identifying valuable documents, misjudgment inevitably occurs, which affects the acceptance rate of financial service equipment
