Problems solved by technology

The main disadvantages of this method are: it is difficult to achieve uniqueness in the analysis of the collected images, that is, it may be misjudged. In addition, there are various external factors during the use of the tested bills, which may cause the The image changes, which reduces the accuracy of identifying the authenticity of the bill

Embodiment Construction

[0027] The bill authenticity identification method and equipment provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, it is a schematic structural diagram of the bill authenticity identification device provided by the present invention, including: a bill supporting part 2 for supporting or fixing the bill 1 to be tested, a control part, a transmitting probe 3 and more than one sensor 4; the output terminal of the control part It is connected with the emission probe 3, and the input end of the control part is connected with the sensor 4.

[0029] In order to reduce the attenuation of the sound wave transmission process, the transmitting probe may be in contact with the bill under test and / or the sensor may be in contact with the bill under test.

[0030] The control unit includes: a central processing unit, a coded signal output channel and a sound wave signal input channel, the o...

Abstract

The invention provides bill authenticity identification equipment and method. The method comprises the steps of: sending a coding signal to a tested bill, collecting the reflection wave of the tested bill, and performing characteristic analysis on the reflection wave to judge the authenticity of the tested bill. Therefore, the bill authenticity identification of the invention is material identification on the bill instead of outline identification, thereby improving the bill authenticity identification accuracy and identification speed.

Description

technical field [0001] The invention belongs to the technical field of bill recognition, and in particular relates to a bill authenticity recognition device and method. Background technique [0002] With the development of society, the proportion of bill transactions in the national economy is increasing, and the amount is sometimes very large. Therefore, the role of bills in market exchange and circulation is becoming more and more important. Therefore, its security requirements are much higher than cash transactions. [0003] In order to improve the security of bill transactions, anti-counterfeiting marks are often set on the bills. Existing bill authenticity identification methods usually include the following two categories: the first type, manual direct identification based on experience: that is, to identify the authenticity by directly observing the anti-counterfeiting mark on the bill, the main defect of this method is: due to the current bill forgery The technolog...
