[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0038] Please refer toFigure 1 and Figure 2 This embodiment provides a banknote sorting machine with visual anti-counterfeiting function. The banknote sorting machine includes a frame 1, and an image acquisition device 2, a first memory 3, a second memory 4, and a display unit 5, all disposed on the frame 1. The frame 1 has a coin inlet 11, a coin outlet 12, and a coin return outlet 13. The coin inlet 11 is used to place banknotes to be sorted, the coin outlet 12 is used to receive genuine banknotes that meet preset conditions, and the coin return outlet 13 is used to receive suspicious banknotes. The image acquisition device 2 is used to acquire anti-counterfeiting feature images of the banknotes to be sorted. The first memory 3 is used to store the anti-counterfeiting feature images of genuine banknotes, and the second memory 4 is used to temporarily store the anti-counterfeiting feature images of suspicious banknotes. The display unit 5 has a first display area 51 and a second display area 52. The first display area 51 is used to display the anti-counterfeiting feature images of suspicious banknotes, and the second display area 52 is used to display the anti-counterfeiting feature images of genuine banknotes. The banknote sorting machine provided in this embodiment has a display unit 5. The first display area 51 of the display unit 5 displays the anti-counterfeiting feature image of the suspicious banknote, and the second display area 52 of the display unit 5 displays the anti-counterfeiting feature image of the genuine banknote. Thus, the operator can identify the authenticity of the banknote by comparing the anti-counterfeiting feature image of the suspicious banknote with the anti-counterfeiting feature image of the genuine banknote. Compared with the prior art, there is no need to set up a dedicated banknote authentication device to perform secondary authentication of the suspicious banknote, which reduces the cost of the banknote sorting machine and improves the efficiency of banknote authentication.
[0039] Optionally, in this embodiment, the first memory 3 is a non-volatile memory, and the second memory 4 is a volatile memory. Thus, the first memory 3 can store the anti-counterfeiting feature images of genuine coins, while the second memory 4 can temporarily store the anti-counterfeiting feature images of suspicious coins. Specifically, the anti-counterfeiting feature images of genuine coins can be pre-stored in the first memory 3, while the anti-counterfeiting feature images of suspicious coins can be acquired in real-time by the image acquisition device 2 during the sorting process and temporarily stored in the second memory 4.
[0040] Alternatively, please refer to Figure 3The banknote sorting machine also includes a controller 9 and a conveying mechanism 8. The image acquisition device 2 acquires the anti-counterfeiting feature image of the banknotes to be sorted and transmits it to the controller 9. The controller 9 compares the acquired anti-counterfeiting feature image of the banknotes to be sorted with preset conditions to determine whether the banknotes are genuine banknotes that meet the preset conditions. If the banknotes are determined to be genuine banknotes that meet the preset conditions, the controller 9 controls the conveying mechanism 8 to convey the banknotes to the banknote outlet 12. If the banknotes are determined not to meet the preset conditions, the controller 9 determines that the banknotes are suspicious banknotes. The controller 9 controls the conveying mechanism 8 to convey the banknotes to the banknote return outlet 13. The controller 9 also controls the second memory 4 to temporarily store the anti-counterfeiting feature image of the suspicious banknotes and controls the first display area 51 to display the anti-counterfeiting feature image of the suspicious banknotes. The controller 9 controls the second display area 52 to display the anti-counterfeiting feature image of the genuine banknotes, thereby enabling operators to identify the authenticity of banknotes by comparing the anti-counterfeiting feature images of the suspicious banknotes and the genuine banknotes. It should be noted that the controller 9 controls the image acquisition device 2 and the display unit 5 using existing technology, which can be achieved through existing image acquisition and image display technologies. This embodiment will not elaborate on this further.
[0041] In this embodiment, the preset conditions may include at least one of the following: banknote denomination, banknote version, banknote orientation, and banknote liquidity. The liquidity of a banknote is determined based on any one of the following conditions: its condition (newness or age), degree of damage, and version. For example, when the current version of a banknote matches the version currently in circulation, the banknote is considered suitable for circulation; when the match is not consistent, the banknote is considered unsuitable for circulation. Similarly, when the condition of a banknote meets a set requirement (e.g., the banknote is 60% new or more), it is considered suitable for circulation; otherwise, it is considered unsuitable for circulation. Likewise, when the degree of damage to a banknote is less than 10%, it is considered suitable for circulation; otherwise, it is considered unsuitable for circulation.
[0042] Alternatively, please refer to Figure 1 and Figure 2 The coin return slot 13 and the display unit 5 are arranged adjacent to each other along the vertical direction. Since the suspicious coin is transported to the coin return slot 13, by arranging the display unit 5 adjacent to the coin return slot 13, the staff can easily associate and compare the suspicious coin stored in the coin return slot 13 with the anti-counterfeiting feature image of the suspicious coin displayed on the display unit 5 after taking the suspicious coin out of the coin return slot 13, which is convenient for operation.
[0043] Alternatively, please refer to Figure 1 and Figure 2 The coin inlet 11, display unit 5, coin return outlet 13, and coin outlet 12 are arranged sequentially from top to bottom. This arrangement makes the banknote sorting machine more compact, ergonomic, and easier for staff to operate.
[0044] Alternatively, please refer toFigure 1 and Figure 2 The coin outlet 12 includes a first coin outlet 121 and a second coin outlet 122 arranged adjacent to each other in a vertical direction. By setting the first coin outlet 121 and the second coin outlet 122, the banknote sorting machine can classify and store banknotes identified as genuine according to different conditions. For example, the first coin outlet 121 is used to store banknotes suitable for circulation, and the second coin outlet 122 is used to store banknotes unsuitable for circulation.
[0045] Alternatively, please refer to Figure 4 In this embodiment, the display unit 5 is a touch screen, and the first display area 51 and the second display area 52 are integrated into the touch screen. This configuration, by simultaneously setting the first display area 51 and the second display area 52 on the touch screen, allows the two display areas to respectively display the anti-counterfeiting feature images of suspicious banknotes and genuine banknotes, effectively reducing the cost of the banknote sorting machine.
[0046] Optionally, the images displayed in the first display area 51 and the second display area 52 can both be zoomed in or out via touch operation, and the images displayed in the first display area 51 and the second display area 52 can be zoomed in or out synchronously. Specifically, when the operator touches the first display area 51 and zooms in or out on the anti-counterfeiting feature image of the suspicious coin displayed in the first display area 51, the anti-counterfeiting feature image of the genuine coin displayed in the second display area 52 is zoomed in or out synchronously; similarly, when the operator touches the second display area 52 and zooms in or out on the anti-counterfeiting feature image of the genuine coin displayed in the second display area 52, the anti-counterfeiting feature image of the suspicious coin displayed in the first display area 51 is zoomed in or out synchronously. This setting facilitates the operator's observation of the details of the anti-counterfeiting feature images, thereby making it easier for the operator to make comparisons. The synchronous zooming in or out operation of the images displayed in the first display area 51 and the second display area 52 is prior art and will not be elaborated upon here.
[0047] Alternatively, please refer to Figure 3 The first display area 51 and the second display area 52 are arranged side by side in the left-right direction, or the first display area 51 and the second display area 52 are arranged in the up-down direction. With this arrangement, the first display area 51 and the second display area 52 are adjacent to each other, which makes it convenient for staff to compare the anti-counterfeiting feature images of suspicious coins with those of genuine coins.
[0048] As an alternative, the display unit 5 includes a first display screen and a second display screen, with a first display area 51 disposed on the first display screen and a second display area 52 disposed on the second display screen. This arrangement allows for the display of anti-counterfeiting feature images of suspicious banknotes and genuine banknotes on the two screens respectively, facilitating efficient use of the banknote sorting machine's installation space and improving space utilization. Optionally, the first display screen is embedded in the housing of the frame 1, and the second display screen is connected to the banknote sorting machine's communication interface via a cable. This arrangement allows for the upgrade of the traditional banknote sorting machine through firmware upgrades and the connection of the first display screen, enabling the traditional banknote sorting machine to possess visual anti-counterfeiting capabilities, i.e., the functionality of the banknote sorting machine provided in this embodiment.
[0049] Alternatively, please refer to Figure 4 The first display area 51 is also used to display the automatic counterfeit detection conclusion. The banknote sorting machine also includes a first button 61 and a second button 62. The first button 61 is used to accept the automatic counterfeit detection conclusion, and the second button 62 is used to reject the automatic counterfeit detection conclusion. This configuration allows the conclusion of automatically determining the authenticity of suspicious banknotes to be displayed on the display unit 5 for staff reference, improving staff efficiency. Simultaneously, by providing a first button 61 for accepting the automatic counterfeit detection conclusion and a second button 62 for rejecting it, the decision-making power regarding the identification result remains with the staff, thereby improving the accuracy of the judgment. Preferably, the first display area 51 is used to display the first button 61 and the second button 62. This configuration allows the first button 61 and the second button 62 to be touch-operated buttons, reducing the cost of the banknote sorting machine compared to mechanical buttons, and also achieving a compact structure. Of course, in other embodiments, the first button 61 and the second button 62 can also be set as mechanical buttons as needed.
[0050] For example, the automatic counterfeit detection conclusion can include two conclusions: genuine currency and counterfeit currency. Specifically, the controller 9 compares the anti-counterfeiting feature image of the suspicious currency with the anti-counterfeiting feature image of the genuine currency. If the similarity between the two reaches a set value, the automatic counterfeit detection conclusion is that the currency is genuine. If the similarity between the two does not reach the set value, the automatic counterfeit detection conclusion is that the currency is counterfeit. Under the control of the controller 9, the automatic counterfeit detection conclusion is displayed in the first display area 51.
[0051] Alternatively, please refer to Figure 2The machine frame 1 is equipped with a banknote conveying channel 14, with the banknote inlet 11, banknote outlet 12, and banknote return outlet 13 all connected to the banknote conveying channel 14. The image acquisition device 2 includes a multispectral image sensor 21 and a magnetic image sensor 22 spaced along the banknote conveying channel 14. The anti-counterfeiting feature images of the suspicious banknote include color images, infrared reflection images, infrared transmission images, ultraviolet reflection images, and magnetic feature images. The multispectral image sensor 21 is used to acquire the color images, infrared reflection images, infrared transmission images, and ultraviolet reflection images of the banknote, while the magnetic image sensor 22 is used to acquire the magnetic feature images of the banknote. This configuration, by using the multispectral image sensor 21 and the magnetic image sensor 22 to acquire different anti-counterfeiting feature images of the banknote, allows staff to comprehensively compare the anti-counterfeiting feature images of the suspicious banknote, thereby accurately determining its authenticity. Specifically, in this embodiment, the multispectral image sensor 21 includes at least an infrared light source and an ultraviolet light source. The banknote has various anti-counterfeiting features, including intaglio printing features, letterpress printing features, and infrared-excited anti-counterfeiting ink features, which need to be illuminated by the infrared light source and reflected in the image acquired by the multispectral image sensor 21; fluorescent ink features, fluorescent fiber filaments, etc., need to be illuminated by ultraviolet light and reflected in the image acquired by the multispectral image sensor 21; and magnetic ink features need to be acquired by a magnetic sensor and reflected in the magnetic feature image.
[0052] Alternatively, please refer to Figure 2 and Figure 3 The conveying mechanism 8 includes a motor 81 and multiple rollers 82 that are connected to the motor 81 for driving the movement of banknotes located in the conveying channel 14. The controller 9 is communicatively connected to the motor 81.
[0053] Alternatively, please refer to Figure 3 The first display area 51 is used to display color images, infrared reflection images, infrared transmission images, ultraviolet reflection images, and magnetic feature images of suspicious banknotes one by one. The second display area 52 is used to simultaneously display the anti-counterfeiting feature images of genuine banknotes corresponding to the anti-counterfeiting feature images of suspicious banknotes. The banknote sorting machine also includes a third button 71 for flipping up the anti-counterfeiting feature images of suspicious banknotes and a fourth button 72 for flipping down the anti-counterfeiting feature images of suspicious banknotes. With this configuration, the anti-counterfeiting feature images of suspicious banknotes include multiple images, which are temporarily stored in the second memory 4. The controller 9 controls the first display area 51 and the second display area 52 to simultaneously display multiple anti-counterfeiting feature images corresponding to suspicious banknotes and genuine banknotes one by one, so that the staff can easily compare the anti-counterfeiting features of suspicious banknotes with the anti-counterfeiting feature images of genuine banknotes, thereby quickly and accurately determining the authenticity of suspicious banknotes.
[0054] Optionally, please refer to again Figure 3The first display area 51 is also used to display the third button 71 and the fourth button 72. This configuration makes the third button 71 and the fourth button 72 touch-operated buttons, reducing the cost of the banknote sorting machine compared to mechanical buttons, while also achieving a compact structure. Of course, in other embodiments, the third button 71 and the fourth button 72 can also be configured as mechanical buttons as needed.
[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
