Example Embodiment

[0016] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0017] As shown in the figure, a magnetic image detection system is composed of a banknote guide plate 101; a CIS102; a banknote detection sensor 103; a pressure roller 104;

[0018] CIS light sources include visible light, infrared light, ultraviolet light, etc.; two CISs can detect ultraviolet, visible light (red light, green light, blue light or mixed light), and infrared light signals; two CISs and their light sources can work at the same time without interfering with each other ; During the detection process, each CIS light source is lit in time, and the CIS can measure the optical signals (including optical images) of different spectra in time at the corresponding lighting time, so a variety of optical images can be detected in one pass.

[0019] The banknotes enter the first CIS 102 from the banknote guide plate 101. The CIS 102 collects th...

Abstract

The invention relates to a 2-CIS (Contact image sensor) image detection system for identifying notes which consists of two CIS detection devices and comprises a note guide plate. The upper end of a first CIS detection device is provided with a CIS and the lower end of the first CIS detection device is provided with a center shaft; the outer ring of the center shaft of the first CIS detection device is provided with a pressure roller; the lower end of a second CIS detection device is provided with a CIS and the upper end of the second CIS detection device is provided with a center shaft; the outer ring of the center shaft of the second CIS detection device is provided with a pressure roller; the contact surfaces of the CISs and the outer rings of the center shafts are provided with CIS light sources; and a note true-and-false checking detection sensor is arranged on the CISs. Due to the adoption of two-CIS detection, the identification rate of counterfeit money is improved, the counterfeit money is prevented from flowing into the circulation domain, the property damage is reduced and the safety order of the money market in the financial system is maintained.

Description

【Technical field】 [0001] The invention relates to a banknote authenticity detection system for a banknote counting machine, in particular to the technical field of a 2CIS image detection system for banknote identification applied to a banknote counting machine. 【Background technique】 [0002] Banknotes have been widely used in today's society, and with the development of science and technology, especially the development of printing technology, there is a trend of counterfeiting banknotes, and various counterfeiting technologies are emerging one after another. The detection device of the existing banknote counting machine can only perform image detection on the banknotes once. Although the device can detect the authenticity of most banknotes, for some banknotes with high simulation technology, only one detection will cause some counterfeit banknotes to be regarded as genuine banknotes. Passing the test will cause it to flow into the circulation field, causing losses to peopl...
