Description

Technical Field

[0001] The present invention relates to the technical field of banknote verification, and in particular to a system and device for detecting the authenticity of banknotes. Background Art

[0002] As economic activities become more frequent, the circulation of counterfeit currency has become a major problem plaguing the financial system. To this end, existing authenticity detection technologies mainly rely on a variety of identification methods such as magnetic ink sensing, infrared transmission analysis, and fluorescence reaction detection. Although these technologies are effective, they still need to be improved in terms of portability, cost control, and accuracy.

[0003] With the increasing popularity of online payment, cash payment is becoming less and less common. However, some customers still use banknotes to conduct small-denomination transactions. However, due to size issues, many offline stores no longer equip money counters and other equipment with banknote authenticity detection functions in order to reduce the space they occupy. In addition, it is not convenient to detect small-denomination banknotes, and usually only ultraviolet light is used for detection, which can easily lead to false detections. Summary of the invention

[0004] In order to solve the problem that the existing money counting machines are not convenient for detecting small-denomination banknotes, and usually only ultraviolet light is used for detection, which is prone to false detection, the present application provides a banknote authenticity detection system, and the specific solution is as follows.

[0005] A banknote authenticity detection system includes a light source control module, an acquisition module, a processing module, a judgment module, and a display module; The light source control module is used to emit light to illuminate banknotes, and the light source includes ultraviolet rays, infrared rays, and white light; The acquisition module is used to acquire images of banknotes under ultraviolet light, infrared light and white light respectively; The processing module is used to process the three banknote images acquired by the acquisition module and integrate the anti-counterfeiting features of the banknotes; The judgment module is used to judge the acquired banknote image to obtain the banknote authenticity data; The display module is used to display the authenticity of the banknote and to compare and display the differences between the banknote and the range of features of the real banknote.

[0006] By adopting the above technical scheme, the light source control module can emit ultraviolet rays, infrared rays, and white light, and at the same time, the banknote image under the illumination of different light sources can be acquired through the acquisition component, and then the banknote image is judged by the judgment module to complete the judgment of the authenticity of the banknote. Then, the authenticity result can be displayed through the display module. Three types of detection can be performed at one time, which improves convenience and reduces the possibility of false detection.

[0007] Optionally, a standard model library is also included, in which the anti-counterfeiting feature data of real banknotes under ultraviolet light, infrared light and white light are stored. The standard model library is used for the judgment module to compare the anti-counterfeiting features of banknote images with real banknotes.

[0008] By adopting the above technical solution and setting up a standard model library, when obtaining a banknote image, the banknote image to be detected can be directly compared with the anti-counterfeiting features of the real banknote, thereby reducing the possibility of false detection and further improving the accuracy of detection.

[0009] Optionally, a control module is also included, and the control module is used to control the light source control module and the display module.

[0010] By adopting the above technical solution, a control module is set up, which can adjust the light source control module to control the light source, and at the same time control the display module to display the data to be displayed.

[0011] Optionally, a cleaning module is further included. When the processing module determines that there are defects on the banknote, the cleaning module can spray a cleaning agent toward the banknote and clean it.

[0012] By adopting the above technical solution, the cleaning module can attempt to clean the banknote when defects are detected on the banknote. After cleaning, it is easier to judge the anti-counterfeiting features of the banknote, further reducing the possibility of false detection and further improving the accuracy of detection.

[0013] Optionally, a drying module is further included, wherein the drying module is used to dry the cleaning agent after the cleaning module works, and the drying module sends a signal to the acquisition module to acquire the banknote image again after working.

[0014] By adopting the above technical solution and setting a drying module, the banknotes can be quickly dried after cleaning, reducing the possibility of damage to the banknotes due to moisture.

[0015] Optionally, it also includes an AI repair module. When the banknote image is obtained again after the processing module processes, cleans, and dries and there are still defects, the AI ​​repair module is used to repair part of the banknote image and mark the repaired anti-counterfeiting feature part. The banknote image repaired by the AI ​​repair module is transmitted to the judgment module for judgment.

[0016] By adopting the above technical solution and setting up an AI repair module, the banknote can be supplemented according to the AI ​​algorithm when the features of the banknote are incomplete. The AI ​​repair module will supplement the banknote according to the existing features of the banknote. Therefore, when the existing features are completely correct, the supplemented features will also be correct. However, when the existing features are counterfeit, the supplemented features will also complete the counterfeit features. During the comparison, the banknote will not be directly judged as a counterfeit due to defects, and the situation where the authenticity judgment is affected by the missing part of the features is reduced. When the defects are small and few, the authenticity of the banknote can be directly judged. However, when the defects are many and large, the supplemented part will be marked, and the authenticity of the banknote will be further judged, which will reduce the situation where the defects are too large next time and the AI ​​supplement is completely different from the original banknote, thereby further improving the accuracy of the judgment.

[0017] In order to solve the problem that the existing money counting machines are not convenient for detecting small-denomination banknotes, and usually only ultraviolet light is used for detection, which is prone to misdetection, the present application also provides a banknote authenticity detection device, and the specific solution is as follows.

[0018] The above-mentioned banknote authenticity detection system includes a main body, a detection groove is opened at the bottom of the main body, and the detection groove is arranged corresponding to the shape of the banknote. The upper part of the detection groove is also opened with a mounting groove. The light source control module includes an ultraviolet lamp, an infrared lamp and a white light lamp, and the ultraviolet lamp, infrared lamp and white light lamp are all arranged in the mounting groove. The acquisition module includes an acquisition element, and the acquisition element is also arranged in the mounting groove. The display module includes a display element, and the display element is arranged on the top wall of the main body.

[0019] By adopting the above technical solution, a detection slot is opened in the main body, and the banknote can be detected by embedding the banknote in the detection slot. At the same time, the banknote is illuminated by ultraviolet light, infrared light and white light to obtain the corresponding banknote image, and the detection can be completed by comparing the banknote image with the anti-counterfeiting features of the real banknote. The whole device is more convenient to carry, and can detect single small-denomination banknotes, thereby improving the detection accuracy.

[0020] Optionally, the acquisition element includes a spherical camera, which is rotatably connected in the mounting groove and can rotate along the three-dimensional coordinate axis. The cleaning module includes a spray head, and the drying module includes a drying fan. The spray head and the drying fan are both arranged on the spherical camera and rotate with the spherical camera.

[0021] By adopting the above technical solution, a rotatable spherical camera is provided, and the spherical camera can be rotated to obtain the anti-counterfeiting feature. At the same time, the spray head can rotate together with the spherical camera. When it is aimed at the anti-counterfeiting feature, cleaning can be carried out, and the drying fan can also dry the cleaned area at the same time.

[0022] Optionally, a pressing plate is further provided at the position of the main body corresponding to the detection slot. The pressing plate is slidably connected to the main body and driven by a motor and a screw rod. The pressing plate is arranged along the length direction of the detection slot and slides along the width direction of the detection slot. The pressing plate is arranged in a shape corresponding to the detection slot and is used to flatten banknotes.

[0023] By adopting the above technical solution, a pressing plate is provided, which can press the banknotes in the detection slot to flatten the wrinkles of the banknotes, thereby further improving the accuracy of detection.

[0024] Optionally, a sponge block is further provided on the pressing plate, the sponge block is fixedly connected to the pressing plate, and the sponge block is used to abut against banknotes.

[0025] By adopting the above technical solution and setting a sponge block, the sponge block can reduce the damage to the banknotes caused by flattening the banknotes. At the same time, the sponge block can also absorb the cleaning agent when moving, thereby improving the drying effect of the cleaning agent.

[0026] In summary, this application has at least the following beneficial effects: 1. The present application solves the problem that the existing money counting machines are not convenient for detecting small-denomination banknotes. Usually, only ultraviolet light is used for detection, which is prone to false detection. The present application is configured to irradiate banknotes with ultraviolet light, infrared light, and white light, and can irradiate banknotes with multiple lights at one time for authenticity detection, thereby improving the convenience of detection and improving the accuracy of detection.

[0027] 2. The present application solves the problem that the existing money counting machines are not convenient for detecting small-denomination banknotes. Usually, only ultraviolet light is used for detection, which is prone to misdetection. Banknotes can be detected by embedding them into the detection slot of the main body, which is more portable and more convenient for detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0034] Embodiment 1 like Figure 1 As shown, a system for detecting the authenticity of banknotes includes a light source control module 1, an acquisition module 2, a processing module 3, a judgment module 4, and a display module 5; the light source control module 1 is used to emit a light source to illuminate the banknotes, and the light source includes ultraviolet rays, infrared rays, and white light; the acquisition module 2 is used to obtain images of banknotes under ultraviolet rays, infrared rays, and white light respectively; the processing module 3 is used to process the three banknote images acquired by the acquisition module 2 and integrate the anti-counterfeiting features of the banknotes; the judgment module 4 is used to judge the acquired banknote images to obtain the authenticity data of the banknotes; the display module 5 is used to display the authenticity results of the banknotes and compare and display the differences between the banknotes and the range features of the real banknotes. In specific implementation, one of the lights is firstly irradiated by the light source control module 1, and the acquisition module 2 obtains the first image, and then the images of the banknotes under the illumination of the three light sources are repeatedly obtained, so that the authenticity of the banknotes can be judged, and then the results are displayed through the display module 5. In other embodiments, a fluorescent reaction module can be added to further detect the banknotes.

[0035] like Figure 1 As shown, the standard model library 41 is also included. The standard model library 41 stores the anti-counterfeiting feature data of genuine banknotes under ultraviolet light, infrared light, and white light. The standard model library 41 is used for the judgment module 4 to compare the banknote image with the anti-counterfeiting feature of the genuine banknote. In specific implementation, the standard model library 41 stores the anti-counterfeiting feature data of banknotes of various denominations under various light sources for detection. When judging the authenticity of banknotes, the authenticity conclusion can be drawn by comparing the image and the data, thereby improving the accuracy of detection.

[0036] like Figure 1 As shown, it also includes a control module 6, which is used to control the light source control module 1 and the display module 5. In specific implementation, the selection of the light source and the display module 5 displaying the image and the detection result are all controlled by the control module 6.

[0037] like Figure 1As shown, it also includes a cleaning module 7. When the processing module 3 determines that there are defects on the banknote, the cleaning module 7 can spray a cleaning agent toward the banknote and clean it. It also includes a drying module 72. The drying module 72 is used to dry the cleaning agent after the cleaning module 7 works. After the drying module 72 works, it sends a signal to the acquisition module 2 to acquire the banknote image again. In specific implementation, the cleaning module 7 can spray alcohol or other small amounts of cleaning agents with mildew removal and decontamination on the banknote, and then dry the cleaning agent by drying, thereby reducing the influence of defects on the accuracy of banknote detection to a certain extent.

[0038] like Figure 1 As shown, it also includes an AI repair module 31. When there are still defects in the banknote image obtained again after the processing module 3 processes, cleans, and dries, the AI ​​repair module 31 is used to repair part of the banknote image and mark the repaired anti-counterfeiting feature part. The banknote image repaired by the AI ​​repair module 31 is transmitted to the judgment module 4 for judgment. In specific implementation, when the defect is small, the banknote image repaired by the AI ​​repair module 31 is completed according to the anti-counterfeiting feature on the banknote. At this time, there will be no deviation between the repaired banknote image and the banknote image in the standard database, which can reduce the situation of misdetection due to defects. When the defect is large, the banknote may not have anti-counterfeiting features at all, or the anti-counterfeiting features are too few to be repaired. At this time, the banknote image repaired by AI no longer has comparison significance, so the banknote image repaired by the AI ​​repair module 31 at this time Working principle: After the banknotes are put in, the light source control module 1 will illuminate the banknotes with multiple light sources and obtain the image of the banknotes. At the same time, the banknotes with defects will be cleaned and repaired. Then, by comparing the data in the standard model library 41, the authenticity of the banknotes can be determined.
