[0002] Based on the multispectral anti-counterfeiting analyzer of patent 202220727798X, the original equipment is equipped with three types of cameras: global, local magnification and macro magnification. Combined with top white light, ultraviolet and laser light sources, side white light and infrared light sources, and bottom white light and infrared light sources, it can collect multispectral scene images. The system controls the display to realize the synchronous comparison between the real image and the banknote pattern, and assists manual banknote verification.

[0003] This upgrade adds a bottom-mounted automatic banknote feeding and recognition module. After detecting a banknote, the device activates the conveying mechanism to send the banknote into the banknote verification channel. The channel is equipped with a counterfeit detection sensor that collects transmission / reflection images, feature information, and magnetic data of the banknote under red, green, blue, infrared, and ultraviolet spectra. In the horizontal banknote feeding mode, a banknote feeding sensor is installed at the banknote inlet. Two multispectral CIS image tubes are arranged in the channel to collect multispectral images, a fluorescence device acquires fluorescence information, and multiple magnetic sensors collect magnetic images and magnetic features of the security thread. The horizontal banknote feeding structure optimizes the acquisition of the magnetic strength of the security thread and multi-dimensional magnetic waveform features.

[0004] The system uses a banknote verification algorithm to determine authenticity and outputs the results. Combined with audio-visual prompts, it forms a closed-loop process. Compared with the previous generation of equipment, this solution has improved in automatic multispectral image recognition, serial number recognition, and magnetic feature detection.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Reference Figures 1-6 An identification instrument, the main structure of which consists of an identification base 5, a bottom cover assembly 4, a box body, a mechanism assembly 3, and a series of related auxiliary components.

[0033] The bottom cover assembly 4 serves as the stable supporting foundation for the entire authentication device. Its top is precisely and sequentially bolted to the left side cover assembly 6, the second left side plate assembly 7, the second right side plate assembly 8, the right side cover assembly 9, the rear cover assembly 10, and the opening / closing door panel 11. These components combine to form a relatively enclosed and structurally stable box, providing protection for the internal components and ensuring the integrity of the overall structure. The display assembly 1 is securely bolted to one side of the box. The display assembly 1 uses a high-resolution LCD screen, which can clearly and intuitively display the authentication results, such as the authenticity, denomination, and version of the banknotes. It also features operation prompts and fault alarms for user convenience.

[0034] The mechanism assembly 3 is located on top of the bottom cover assembly 4, and the circuit board assembly 2 is mounted on it. It integrates key components such as a microprocessor, memory, and signal processing circuits, responsible for processing signals collected by various sensors, performing data analysis, processing, and judgment, and displaying the results on the display assembly 1. It also transmits signals to other components via wires to ensure coordinated operation between them. The bottom cover assembly 4 contains an identification base 5, which is connected to the mechanism assembly 3 via wires to enable data and command interaction. The display assembly 1 is also connected to the mechanism assembly 3 via wires to ensure stable and rapid signal transmission, guaranteeing the real-time performance and accuracy of the displayed content.

[0035] The bottom of the identification base 5 is a base plate assembly 514, which is made of high-strength, wear-resistant metal material. The rear edge of the identification base 5 is hinged to connect with the bottom cover assembly 4, and the front edge is fixed to the bottom of the bottom cover assembly 4 via hooks, providing stable support for the entire identification base 5 and allowing the bottom cover assembly to open and close for convenient daily maintenance. The top of the base plate assembly 514 is bolted to the first right side plate assembly 59 and the first left side plate assembly 510. The first right side plate assembly 59 and the first left side plate assembly 510 are made of aluminum alloy, which is lightweight and high-strength, and their surfaces are anodized to improve corrosion resistance and aesthetics. The first channel plate assembly 511 and the second channel plate assembly 513 are both bolted between the first right side plate assembly 59 and the first left side plate assembly 510, forming a banknote transport channel that can accommodate the transport of banknotes of different denominations and versions.

[0036] The conveying assembly is housed within the identification base 5 to enable banknote conveying. The banknote dispensing wheel assembly 52, magnetic head wheel assembly 53, banknote sorting wheel assembly 55, and banknote feeding wheel assembly 57 are rotatably mounted between the first right side plate assembly 59 and the first left side plate assembly 510 via bearings. These wheel assemblies are all made of high-quality rubber material with a specially treated surface, providing excellent friction and wear resistance to ensure that banknotes do not slip or jam during conveying. A motor is mounted on one side of the first left side plate assembly 510; this motor is a high-performance DC motor with stable speed and high torque. The motor, banknote dispensing wheel assembly 52, magnetic head wheel assembly 53, banknote sorting wheel assembly 55, and banknote feeding wheel assembly 57 are connected by a synchronous belt and synchronous pulleys. The synchronous belt is made of high-strength, high-elasticity polyurethane material, and the synchronous pulleys are made of aluminum alloy with precision-machined surfaces to ensure smooth and accurate transmission. When the motor starts, the synchronous belt and synchronous pulleys drive each wheel assembly to rotate synchronously, thereby conveying the banknotes. It can stably feed banknotes at a speed of 50-100 milliseconds per sheet, and the banknotes are fed smoothly and steadily during the process, ensuring the accuracy of identification. At the same time, the conveying component also has an overload protection function, which can automatically stop the operation when abnormalities such as banknote jams occur, so as to avoid damage to the equipment.

[0037] The first channel plate assembly 511 specifically includes a rear channel plate 5111, which is made of metal to prevent static electricity from being generated during banknote transport. The rear channel plate 5111 is bolted between the first right side plate assembly 59 and the first left side plate assembly 510. A set of first driven pressure rollers 5112 are bolted to the bottom of the rear channel plate 5111. These first driven pressure rollers 5112 are made of rubber with a smooth surface to reduce wear on banknotes. The tops of the two sets of first driven pressure rollers 5112 extend to the top of the rear channel plate 5111 and cooperate with the banknote dispensing roller assembly 52 and the magnetic head roller assembly 53. When banknotes pass through, the first driven pressure rollers 5112 work together with the banknote dispensing roller assembly 52 and the magnetic head roller assembly 53 to ensure smooth banknote transport through friction. An outlet baffle 51 located above and outside the rear channel plate 5111 is also bolted between the first right side plate assembly 59 and the first left side plate assembly 510. The outlet baffle 51 is made of metal and has a polished surface. It serves to guide the banknote output direction and prevent the banknote from deviating or getting stuck during the output process.

[0038] The second channel plate assembly 513 includes a front channel plate 5131, which is also made of metal and together with the rear channel plate 5111 forms a complete banknote conveying channel. The front channel plate 5131 is bolted between the first right side plate assembly 59 and the first left side plate assembly 510. A second driven pressure roller 5136 is bolted to the bottom of the front channel plate 5131. The second driven pressure roller 5136 extends to the top of the front channel plate 5131 and works in conjunction with the banknote feeding roller assembly 57 to ensure that banknotes smoothly enter the identification channel. A banknote separating driven roller assembly 5132 is rotatably mounted between the first right side plate assembly 59 and the first left side plate assembly 510, located below the front channel plate 5131. The banknote separating driven roller assembly 5132 is made of rubber with a special textured surface design to increase friction with banknotes. The banknote sorting driven roller assembly 5132 extends to the top of the front channel plate 5131 and works in conjunction with the banknote sorting roller assembly 55. When multiple banknotes enter simultaneously, the banknote sorting driven roller assembly 5132 and the banknote sorting roller assembly 55 can separate the banknotes one by one through the difference in friction, thus realizing the banknote sorting operation. The first right side plate assembly 59 and the first left side plate assembly 510 are also connected by bolts to a banknote feeding baffle 58 located on the outer side of the front channel plate 5131. The banknote feeding baffle 58 is made of metal and can guide the banknotes to enter the banknote feeding roller assembly 57 accurately, preventing the banknotes from being skewed or jammed during the banknote feeding process. The top of the base plate assembly 514 is bolted to a pressure strip assembly 56 located between the banknote sorting wheel assembly 55 and the banknote feeding wheel assembly 57. The pressure strip assembly 56 includes a banknote feeding pressure strip 561, a sensor bracket 562, and a sensor 563. The sensor bracket 562 is bolted between the first right side plate assembly 59 and the first left side plate assembly 510. The sensor 563 is bolted to one side of the sensor bracket 562. The banknote feeding pressure strip 561 is bolted to one side of the sensor bracket 562. It can apply a certain pressure to the banknote to ensure the flatness of the banknote during the transportation process and improve the accuracy of identification.

[0039] The testing agency uses multispectral analysis to identify banknotes during transport. A magnetic base 5133, made of a highly magnetically permeable metal, is bolted to the bottom of the front channel plate 5131. Two short magnets 5135 and a long magnet 5134 are embedded in the top of the magnetic base 5133. The short magnets 5135 and the long magnet 5134 are made of high-performance neodymium iron boron magnetic material, characterized by strong magnetism and good stability. When a banknote passes by, the magnetic field generated by the magnets magnetizes the magnetic material on the banknote. The bottom of the rear channel plate 5111 is bolted to two short magnetic head assemblies 5114 and a long magnetic head assembly 5113 located between the two short magnetic head assemblies 5114. The short magnetic head assemblies 5114 and the long magnetic head assembly 5113 use high-precision magnetic sensors, which can accurately collect the security thread and magnetic ink of the banknote for magnetic identification. Different denominations and versions of banknotes have different magnetic characteristics. By detecting changes in magnetic information, the authenticity and characteristics of the banknote can be determined, further improving the accuracy of identification. In addition, the lower image tube assembly 512 and the upper image tube assembly 54 are bolted to the first right side plate assembly 59 and the first left side plate assembly 510. A paper feeding channel is provided between the lower image tube assembly 512 and the upper image tube assembly 54, through which the banknote passes during the transport process. The upper image tube assembly 54 and the lower image tube assembly 512 are vertically aligned. The upper image tube assembly 54 includes an upper image tube bracket 541, an image tube mounting base 542, and an image tube 543. The upper image tube bracket 541 is fixed between the first right side plate assembly 59 and the first left side plate assembly 510 by glass beads 5101. The image tube mounting base 542 is bolted to the bottom of the upper image tube bracket 541. The image tube 543 is fixedly connected to the bottom of the image tube mounting base 542 by an image tube fixing piece 544. This assembly can quickly and accurately acquire multispectral image information of banknotes. By analyzing the color, texture, and pattern features of the image, it can be used to identify the authenticity of banknotes.

[0040] This application can be used in the field of banknote authentication, or in other fields applicable to this application.

[0041] Example 2

[0042] refer to Figures 1-6A multispectral analysis and identification instrument is applied to the field of banknote identification. A macro component 12 is bolted to one side of the second left side panel assembly 7. The macro component 12 employs a high-precision optical lens and image sensor, enabling high-precision detection of local features of the banknote, such as watermarks, security threads, and microtext, further enhancing the reliability of identification. When a banknote passes through the detection area of ​​the macro component 12, the macro component 12 can quickly acquire a local image and determine the authenticity of the banknote by comparing it with a preset standard image. A printing component 13 is bolted to the outside of the right side cover assembly 9. The printing component 13 uses thermal printing technology, featuring fast printing speed, low noise, and high print quality. After identification is completed, the printing component 13 can print the identification results and related information as needed, such as the banknote's denomination, authenticity determination, and identification time, facilitating user recording and archiving.

[0043] When in use, according to the device prompts, place the banknote into the identification base 5. During the placement process, the banknote enters between the banknote feeding baffle 58 and the second channel plate assembly 513, and is located between the banknote feeding wheel assembly 57 and the two second driven pressure rollers 5136. At this time, the internal motor controls the banknote feeding wheel assembly 57 to rotate. During the rotation of the banknote feeding wheel assembly 57, it can cooperate with the first driven pressure roller 5112 to transport the banknote, so that the banknote passes through the long magnet 5134 and the short magnet 5135, which can identify the magnetic features of the banknote.

[0044] After being guided by the pressure strip assembly 56, the banknotes enter between the banknote sorting wheel assembly 55 and the banknote sorting driven wheel assembly 5132. The banknote sorting wheel assembly 55 is then driven by a motor to rotate, and the banknote sorting driven wheel assembly 5132 continues to transport the banknotes. As the banknotes pass between the lower image tube assembly 512 and the upper image tube assembly 54, the lower image tube assembly 512 and the upper image tube assembly 54 can acquire multispectral images of the banknotes for image recognition under different spectra. Different denominations and versions of banknotes have different spectral images. By detecting the spectral images, the characteristics and authenticity of the banknotes can be determined.

[0045] When the banknote passes between the banknote delivery wheel assembly 52, the magnetic head wheel assembly 53 and the two sets of first driven pressure rollers 5112, the banknote delivery wheel assembly 52 and the magnetic head wheel assembly 53 are driven to rotate again by the motor, and the banknote is transported by the first driven pressure rollers 5112, so that the banknote is moved out between the exit baffle 51 and the first channel plate assembly 511.

[0046] At the same time, the identification information is displayed through display component 1.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
