Description

Technical field

The invention relates to methods and devices for checking and determining the authenticity, dignity and degree of decay (deterioration) of money tickets, their accounts and sorting. It can be used in bank sorting devices for sorting cash tickets (banknotes), determining their solvency, searching and identifying dilapidated and fake cash tickets.

The device for sorting and counting cash tickets is intended for the automatic processing of cash tickets of any kind, dignity and nationality. The method on which the operation of the device is based is to determine the authenticity, dignity, and degree of disrepair of the money ticket from the full images of both sides of the money ticket obtained on scanning devices in the visible spectral region, the infrared region of the spectrum, and the induced image obtained when illuminated in the ultraviolet region of the spectrum, transmitted and processed in the computing unit, where, using a pre-installed software for pattern recognition, the image obtained is compared eny with the reference.

The device automatically sorts into a separate bunker with the status suitable (intended for further circulation) and into a separate bunker (dilapidated due to physical condition). Money tickets that do not meet the specified denomination or sample, have violations in some form of protection, glued together, and also can not be recognized, are sorted into a separate bin for subsequent analysis by an expert. Sorting parameters (criteria) can be changed and adjusted by the user in accordance with his requirements through an interactive interface for adjusting sorting parameters through the display and keyboard. The device keeps a record of its work, and, therefore, can perform accounting and control functions.

State of the art

A device for sorting and counting money tickets Ee Lia Kie 3700 of the company Ee Lia Kie [1] is known, in which a method is used to determine the authenticity and dignity of money tickets based on checking the presence of tags in certain places of money tickets using infrared and ultraviolet sensors. In order to protect against counterfeiting, an image is applied with a so-called metamer paint, this image is not visible to the ordinary eye and appears only in the infrared spectrum. Knowing a specific infrared image, a sensor can be developed that checks the presence or absence of metamer paint at several specific points on the surface of a money ticket. This sensor is a pair: an infrared emitter and a photodetector that receives reflected radiation from paper. In the absence of metamer paint, the photodetector is illuminated by reflected light; in the presence of paint, the light flux on the photodetector decreases.

When a money ticket is illuminated with ultraviolet radiation, induced visible radiation occurs. Knowing the specific induced image, it is possible to develop a sensor that checks the presence or absence of the induced image at several specific points on the surface of the money ticket. This sensor is a pair: an ultraviolet emitter and a photodetector that receives induced radiation from paper. In the presence of an induced image, the photodetector is illuminated by reflected light; in the absence of an induced image, the light flux at the photodetector decreases.

The disadvantage of this method is not checking the entire image, but only checking the presence or absence of the image at several points on the surface of the money ticket.

The degree of deterioration of a money ticket in the known method is checked using a microphone sensor for the noise level of a creased money ticket, while such significant signs of decay as dirty spots and inscriptions may not be noticed.

The advantage of the money ticket in the known method is checked by a special sensor, which is a light source and many optical fibers that collect reflected light along several bands of the surface of the money ticket, these optical fibers are collected at the exit to the beam and transmit the integrated illumination to the photodetector. When passing a cash ticket under the sensor on the photodetector, various integral illumination curves are obtained depending on the value. This method does not guarantee an error-free determination of the value of a cash ticket.

The known machine has a unit for the delivery of cash tickets, a transport system for delivering cash tickets to the sensors (detectors) of the control unit for passing and counting cash tickets, a unit for determining the authenticity, dignity and decrepitude of cash tickets, there is a unit for splitting the flow of cash tickets for sending cash tickets in one from stacking nodes with a capacity, depending on the decision made by the computing unit on the basis of data received from sensors, three stacking nodes with containers for folding the recalculated and calculated sorted cash tickets: one for eligible tickets, the second for decrepit ones, and the third for cash tickets of doubtful authenticity and dignity. A disadvantage of the known machine is the need to rebuild and replace a set of sensors during the transition to another type of cash ticket, for example, cash ticket of another country. Redesigning, manufacturing and debugging another sensor system for a new type of cash ticket requires time, considerable resources and effort, as well as large financial costs.

Disclosure of invention

The objective of the present invention is to develop a method for determining the authenticity, dignity and degree of disrepair of a money ticket, based on scanning a money ticket using scanning devices that allow you to get full images of both sides of a money ticket in the visible spectrum, infrared spectrum, and also an induced image (luminescent and / or fluorescent) obtained by illumination in the ultraviolet region of the spectrum to achieve high reliability with subsequent image processing using the computing unit, and to provide a compact sorting apparatus banknotes and bills, requiring no hardware changes when changing the form of banknotes.

The essence of the method lies in the fact that the money ticket is scanned by scanning devices to obtain a complete image of both sides of the money ticket in the visible region of the spectrum, the infrared region of the spectrum and the induced image obtained by irradiation with ultraviolet light. The obtained images of the surface of the money ticket are transmitted from the scanning devices to the computing unit, in which, using the image recognition software, they are compared with the reference ones and a decision is made on the authenticity, dignity and degree of disrepair of the money ticket. The trained image recognition software installed on the computing unit allows you to recognize the images of money tickets presented to him and give an answer to the question to what extent the entered image matches the reference image. The software tool can determine the complete correspondence of the images, the partial correspondence of the images, the complete discrepancy of the images, the correspondence and the discrepancy of individual fragments of the image.

To determine the value and degree of dilapidation of a money ticket, the software compares the received image of a money ticket in the visible region of the spectrum with the reference one. With the complete discrepancy of the images, the software decides that the cash ticket is of another denomination, with partial discrepancy (spots, inscriptions, tears on the cash ticket, etc.), the software decides the degree of decay of the cash ticket. To determine the authenticity of a money ticket, the software compares the full infrared and induced image obtained when illuminated in the ultraviolet region of the spectrum, the money ticket with the reference. If the images are completely inconsistent, a decision is made about doubting the authenticity of the money ticket. In case of partial mismatch of images, the presence or absence of a pattern in special protection zones on a cash ticket is checked. If the protection zones do not comply, a decision is made on the doubt of the authenticity of the money ticket.

The program allows you to analyze a set of signs of a decrepit cash ticket: deterioration, spots, inscriptions, breakouts at the edges, bent and torn corners, holes, flat tears of the edges.

Based on the threshold data determined by the expert, the image of the money ticket obtained in the visible region of the spectrum, the image of the money ticket in the infrared region of the spectrum and the induced image obtained after the money ticket was illuminated in the ultraviolet region of the spectrum are analyzed, and the decision rules on whether the money ticket belongs to one are constructed of three classes: suitable, dilapidated, doubtful.

The sequence of actions when sorting cash tickets is as follows.

Let the image of money ticket M x M pixels be received from the scanning device. We denote by Ω = (0, M] x (0, M] e K the set of image points. Moreover, each pixel (n) is associated with the area {(ξ, η) € Ω, ξε (; -1, Ληε (ί-1 , /]}, the point (u) e Ω is the upper right corner of the pixel area.

Let Ω _Κ be the set of image points belonging to the money ticket being processed at a given time,

Ω _ο is the set of image points belonging to the standard.

The basic idea of sorting banknotes consists in the representation of the original image cash ticket, a predetermined function ζ = / (ξ, η) , using the plurality of O _s O _2, ... O _n numerical characteristics, followed by withdrawal of the decision rule of accessories monetary ticket to one of the classes:

- suitable;

- dilapidated;

- doubtful.

To set such numerical characteristics, we divide Ω _Κ into a set of K-blocks (recognition areas) K ₁ , K ₂ , ..., K _n , where Κι with Ω _Κ , ΐ = 1, ..., n are square (possibly intersecting) In x In pixel fragments of the image and Ψ * ' ⁼ '

Consider also the set of I-blocks (comparison areas on the standard): Ό ₁ , IX And _n , where Ό; with Ω |). representing square (possibly intersecting) V x V pixel fragments and

In real images, noise is almost always present. Therefore, we will consider the image of a money ticket ζ = / (ξ, η) as an implementation of a random process of two variables, i.e. as a random field in which certain probabilistic characteristics are inherent.

We begin the determination of statistical characteristics by calculating the initial and central moments. In the theory of probability the initial moments t _to the k-th order calculated by the general formula ^ = Σ ^χ ιΡκ ί

where X {, is some value of a discrete random variable X,

R; = P {X = X;} - the probability with which the random variable X takes the value X ;.

Mathematical statistics operates with estimates of these points. As applied to image analysis, the formula takes the form ι В В В

Central moments _and in the theory of probability determined by the expression

For the practical application of the above formula, it is necessary to first estimate the average value of _m. Therefore, we will use the well-known formulas to recalculate the initial moments in the central ₂ and 2 = m2 - m1 and ₃ = m ₃ - 3m ₁ m ₂ + 2m ₁ ² and ₄ = m ₄ - 4m ₁ t ₃ + 6t ₁ ² t ₂ - 3t ₁ ⁴ .

We will also be interested in statistics related to central issues, and entropy.

standard deviation, σ ³ is the asymmetry coefficient,

A — 3 σ is the excess coefficient,

In the analysis of signs of deterioration of a money ticket, information on the spatial frequency, defined as the rate of change in the brightness of image elements divided by the distance at which this change occurs, plays an important role. Information about the spatial frequency allows us to use spatial filters to amplify or remove components of a certain frequency, to highlight some features of the image.

In general, the spatial filtering process can be described as follows.

Let

^a 1m ^a 2M ^a mm

Λ (ξ.η) =

source image and filter weight function, respectively, and

their Fourier transforms. Then / '= / 0 ^ = ^ (^ (^, ν) · Γ _Α ( _Μ , ν))

- there is the result of filtering the image by a £ filter with a weight function of 11.

We examined the basic image analysis and processing methods used in our cash ticketing software.

An analysis of the deterioration of a money ticket occurs in several stages in blocks K, with Ω _κ , ΐ = 1, n. For each block K, with Ω _κ , ΐ = 1, ..., n, a certain functional of the state of the region is calculated, determined at each stage work taking into account the features of the analyzed characteristic. The calculated functional takes the greatest value on the reference area and decreases on less similar areas. The obtained value of the function is compared with the threshold value defined as the maximum percentage deviation from the value of the functional on the reference area, and a decision is made on the status of the area for this stage.

Step 1. Determination of the dignity and degree of decay in the visible spectrum.

Decrepit is a complex of signs of aging of a money ticket: deterioration, spots, inscriptions, breakouts at the edges, bent and torn corners, holes, flat tears of the edges.

Let / (ξ, η) be the image of the current money ticket in the visible region of the spectrum, / ^ρ (ξ, η) be the image of the reference money ticket in the visible region of the spectrum. Initially, 7 the images of the standard and the current cash ticket are divided into K and I blocks described above. For each area of the standard and the analyzed money ticket, the statistical characteristics are calculated: t ₁ , t ₂ , t ₃ , t _d , from, from, id, σ, §1, §2, I ·

To determine the value of a money ticket, we filter the region K ;, ΐ = 1, 2, .. ·, η with a filter with the frequency response E _n (u, y) = E * _O1 , (1), where E _O1 is the Fourier transform of the region C , * is the sign of complex conjugation. Thus, a filter is recorded that is consistent with the image of information O, to be identified, and its mutual correlation with a given image is made. If the image contains the image of interest, then as a result of the correlation at the coordinate origin of the output plane of the system / (ξ, η): (ξ, η) εΚ; a bright light spot is formed, indicating the presence of an identifiable image and location in the desired image.

We set the state function of the region equal to * " _y )>

where α, _ι = [w _v, m2, TK, td and _2, of, id, σ, §1, §2, I , t \, t _2, TK, td, u2, out, Id, σ, § 1, §2, I] is the input feature vector of the domain, components m ₁ , m ₂ , ..., statistical characteristics of the domain after filtration, are the empirically obtained weights of the input features.

In determining the merits of a cash ticket, we will take into account that the conformity of the image is made up of the general (integral) similarity of the entire cash ticket and the presence / absence of a pattern in the controlled areas.

To assess the integral correspondence, we set the state function of the money ticket equal to n

φ = X <p.

r = 1 where [1, // (7 ,.> SG ^φ '<с “'

If, for a given threshold, Ф ^max , Ф> Ф ^max, then the compliance check is performed in controlled areas, otherwise the value of the money ticket does not correspond to the specified one, the money ticket acquires a property - doubtful.

To assess compliance in controlled areas, we introduce an additional binary vector Ι; (0,1), ΐ = 1, ..., η, where C = 1 - for controlled areas, I; = 0 - for the rest. If Ф = П (7?,) = Хд = г л - the dignity does not correspond to the given one, we proceed to the analysis of the signs of a decrepit cash ticket. Otherwise a cash ticket

To determine the degree of deterioration, we set the state function of the cash ticket equal to φ = £ s. · <= 1

If, for a given threshold, Ф ^max , Ф <Ф ^max , then the cash ticket is considered worn out.

To identify spots, we modify (1) as follows:

E _b (u, y) = A (u, y) -E * n ₁ , where A (u, y) is the frequency response of the low-pass filter. We take the state function as in determining the integral correspondence of virtues.

F =. Where

1, / (7,> С, ”“ о, / с, <σ, ““ '

If for a given threshold Φ ^max , Φ <Φ ^max , then the permissible spot area exceeds the threshold.

To identify the inscriptions, we modify (1) as follows:

E _b (u, y) = A (u, y) -E * _O1 , where A (u, y) is the frequency response of the high-pass filter. We take the state function as in determining the integral correspondence of advantages.

P

Ф = Х <р ,, where! / (7,> с ™ О, ϊ / С, <с ™ '

If, for a given threshold, Ф ^max , Ф <Ф ^max , then the allowable area of the inscriptions exceeds the threshold.

To analyze the breakouts at the edges, we use the fact that the background of the substrate is significantly different from the brightness of the edges of the money ticket. Select the edges and define the tolerance in pixels, which determines the distance from the boundary point to the nearest side of the rectangle covering the cash ticket. If at some point the limit tolerance condition is violated and the point does not belong to the neighborhood of the corner of the money ticket determined by the expert, then there are breakouts at the edges of the money ticket.

In determining the bent angle we construct is considered doubtful.

at the boundary points lying in the vicinity of the corner of the money ticket, the regression line is y = ax + b. If at least for one point the distance to the line of the line is greater than the specified one, then the angle is considered to be ragged, otherwise - bent.

A hole is considered to be a section of the image of a money ticket having an intensity close to the dynamic range of brightness of the substrate. We will go through all the pixels of the image of the processed cash ticket and select the connected areas with an intensity close to the substrate. If even the area of one area is larger than the permissible, then there are holes on the money ticket.

Unlike tearing, tearing does not introduce geometric distortions, therefore, it does not always appear on the image of a money ticket. Recognition of tears is performed as a search for lines starting from the edge of a cash ticket in the infrared region of the spectrum. To search for them, we modify (1) as follows:

P _b (u, y) = ((u, y), where Λ (ιι.ν) is the frequency response of the high-pass filter, for example, Laplacians

oh oh

and filter only areas of the current image adjacent to the edge of the cash ticket. After clustering and calculating the area of the lines starting from the edge of the money ticket, a decision is made on the presence of flat tears of the edges, provided that the total area of tears is above the threshold.

Step 2. Verification of ultraviolet protection occurs in the same way as in determining the value, only in the induced image obtained after illumination of a money ticket in the ultraviolet region of the spectrum.

Step 3. Verification of infrared protection occurs in the same way as in determining the value, only in the infrared region of the spectrum.

It should be noted that the thresholds Ф ^max , С ₁ ^max , ί = 1, 2, ..., η are selected separately at each stage of the software and are customizable parameters that directly affect the sorting level of cash tickets. A money ticket is considered dilapidated if it has at least one of the signs of disrepair specified by the operator. Data transmission from scanning devices to the computing unit is synchronized with the speed of movement of cash tickets.

The proposed method for determining the authenticity, dignity and degree of dilapidation of money tickets is implemented in a device for sorting and counting money tickets, consisting of a housing that houses a control unit with an interactive interface for adjusting sorting parameters through the display and keyboard, a unit for sending money tickets from a stack, a transport system for submitting cash tickets to the detectors of the passage control unit and the cash ticket account, the unit for determining the authenticity, dignity and degree of deterioration of cash years, a separation unit for the flow of cash tickets for sending cash tickets to one of the stacking nodes with a capacity, depending on the decision made by the computing unit on the basis of data received from the detectors, stacking nodes with containers for folding the counted and sorted cash tickets, moreover, control of position parameters a magnetic tag detection detector, a solution of guides of the block of units for supplying cash tickets, stacker rotation speed and adjusting the gap between the surface of the rings separating th node and the surface of the feeding belt conveyor track is performed automatically by the control unit depending on the banknotes, pawned in device sizes. The supplying transport unit of the block of units for the delivery of money tickets from the foot has its own separate drive with automatic adjustment of the feed rate depending on the size of the money ticket to be put into the device. A node for clamping the stop of money tickets has been introduced to ensure stable contact of the lower cash ticket of the foot with the transport belts of the feeding unit with a device for monitoring the availability of cash tickets in the stop holder associated with the control of the drive of the clamp unit. The unit for supplying cash tickets is equipped with movable guides with a drive for clearly symmetrical positioning of the stack of cash tickets relative to the longitudinal axis of the transportation mechanism, regardless of the size of the cash ticket. The node for determining the authenticity, dignity and degree of dilapidation of money tickets includes scanning devices that provide a complete image of both sides of the money ticket in the visible region of the spectrum, the infrared region of the spectrum and the induced image obtained by illumination in the ultraviolet region of the spectrum associated with a computing unit located in the block a control that processes the information received from the scanning devices with the help of the software for recognizing one time and passes the decision on the authenticity, dignity and degree of dilapidation of the cash ticket to the cash ticket splitting unit for sending the recounted and sorted cash tickets to one of the packing units with containers. At the same time, a scanning device for obtaining images of a money ticket from one split light stream in the visible zone and infrared zone contains visible and infrared light illuminators, a lens, a translucent mirror, light filters to highlight the visible and infrared regions of the spectrum, and an image pickup device. The scanning device for obtaining a cash ticket image from one split light stream in the infrared region of the spectrum and an induced image obtained by illumination in the ultraviolet region of the spectrum contains ultraviolet and infrared light illuminators, a translucent mirror, a band-pass optical filter that transmits the visible part of the spectrum and a filter for highlighting fractional part of the spectrum, device for capturing images.

The node for determining the authenticity, dignity, and degree of decay of money tickets includes a scanning device for obtaining images in the visible and infrared spectra, a scanning device for obtaining images in the infrared region of the spectrum, and an induced image when illuminated with ultraviolet light, associated with a computing unit that processes received from scanning devices information with the help of a specially developed software for recognizing images pre-installed on them basics and issues a decision on the status of the cash ticket. Scanning devices (scanners), commercially available and used to obtain images of paper documents and input these images into the computing unit, do not allow you to get an image of a paper document simultaneously in two spectral zones (for example, visible and infrared), which makes them unsuitable for determining the authenticity cash tickets. They contain a illuminator, a lens, a CCD line, an electronic device for capturing an image from a CCD line and transferring it to a computing unit. The paper document is illuminated, and the image of this document with the lens is focused on the CCD line, where it is converted into electronic form using an electronic device for taking images from the CCD line and in this electronic form is transmitted to the computing unit.

We use a scanning device to obtain an image of a cash ticket in the visible and infrared regions of the spectrum from one split light stream, shown in FIG. nine.

The specified technical result is achieved by installing after the lens 104 a translucent mirror 105, with the help of which the image of the money ticket is transmitted to two CCD arrays 108 located on one optical axis. At the same time, a light filter is installed in front of one CCD line to highlight the visible region of the spectrum 106, and in front of another a light filter to highlight the infrared region of the spectrum 107. In addition to the illuminator, the infrared illuminator 72 is installed on the scanning device in the scanning region 71.

It is known that on genuine cash tickets in special areas of the picture, the infrared image differs significantly from the visible one. By viewing these areas on the monitor screen, the operator has the ability to determine the authenticity of a cash ticket. When you install image recognition software on a computing unit, the authenticity of a cash ticket is determined automatically.

A scanning device for obtaining images of a cash ticket in the visible and infrared regions of the spectrum operates as follows.

The luminous flux is focused by the lens 104, then it is divided by a translucent mirror 105 into two streams and transmitted to the CCD lines 108. The filters 106 and 107 standing in front of each line form an visible image on one CCD line and an infrared image on the other CCD line. An electronic device 109 captures images from CCD arrays and transmits them to a computing unit.

The proposed machine also uses a scanning device to obtain an image of a cash ticket in the infrared region of the spectrum and an induced image obtained by illumination in the ultraviolet region of the spectrum from one split light stream. This device is shown in FIG. 10.

The specified technical result is achieved by installing after the lens a translucent mirror 105, with which the image is transmitted to two CCD arrays 108, with a light filter installed in front of one ruler to highlight the infrared region of the spectrum 107, and in front of the other a band-pass optical filter that passes the visible part of the spectrum 110 Instead of a conventional illuminator, an ultraviolet illuminator 74 and, in addition, an infrared 72 are mounted on the scanning device.

When scanning a cash ticket, two images are taken - an infrared and an induced image obtained by illumination in the ultraviolet region of the spectrum. It is known that on genuine cash tickets in special areas of the figure, the infrared image and the induced image obtained by illumination in the ultraviolet region of the spectrum differ significantly from the visible. By viewing these areas on the monitor screen, the operator can determine the authenticity of the cash ticket. If there is a software for pattern recognition on the computing unit, the authenticity of a cash ticket can be determined automatically.

The stopper of the block of piece delivery with positioning guides of the stack of cash tickets relative to the longitudinal axis of the transporting device with a drive (see Figs. 1, 3, 4) consists of a restriction plate 23, which serves to support the front of the stack of cash tickets, with a slot in the center to move the clamp device, the front guide 6 and the rear guide 7, which are smooth polished plates. Each of the guides is attached to the carriage 24, which has the ability to move along two cylindrical racks, the front - along the long 25, and the back - on the short 26, mounted in parallel on the mounting plate. The carriages are mechanically connected to the toothed belt 27 located between the carriages, one edge of which is thrown over the smooth pulley 28, and the other edge is engaged on the toothed pulley 29, mounted on the shaft of the electric motor 30. When the motor shaft rotates counterclockwise, the guides synchronously converge to the center, and when rotated clockwise - diverge. The rear guide has a support roller 31. The separating assembly 8 with the drive of the clearance adjustment device (see Figs. 1, 2, 5) consists of a housing 32, on which two axles 33 with non-driving rollers 34 and a drive shaft 35 are attached, fixed to it rollers with grooves for rings 36 and a drive gear pulley 37. The housing through the frame 38 is fixed on an axis 39, rigidly fixed to the mounting plate. The clearance is adjusted by swinging the housing with the frame about the axis. A tab 40, mounted on the housing and transmitting movement to it, is pressed by the spring 41 to the nut 42 and, when the screw 43 is mounted coaxially on the shaft of the electric motor 44, one or the other side raises or lowers the mechanism of the separating assembly. On two sides of the separating unit are auxiliary spring-loaded pinch rollers, consisting of rollers 99, levers 100, axis 101, rigidly fixed to the mounting plate and spring 102. The rollers are constantly pressed against the surface of the transport belts by the spring and create an improved contact between the ticket and the transport belts in the area of the separating unit.

The clamp unit of the stack of cash tickets 9 with the drive of the lifting mechanism (see Figs. 1, 4) consists of two cylindrical guides 45 fixed through holders 46 to the restrictive plate 23, which serves to support the front of the stack of cash tickets, along which the carriage 47 s a clamp 48 fixed thereon from a bent polished sheet having a straight section parallel to the upper part of the stack of cash tickets. The movement down the guides is due to the dead weight of the clamp and the carriage. The clamp is lifted before laying the stack of cash tickets15 by a lifting mechanism consisting of a gear belt 49, one edge of which is thrown over a smooth pulley 50, and the other edge is engaged on a gear pulley 51, mounted on the shaft of the electric motor 52. Between the gear pulley and a smooth pulley a snag 53 is fixed on the toothed belt, which exceeds the size of the groove of the hook 54, which is fixed to the clip carriage through which the belt is passed. When moving up, the noose on the belt rests on the hook and raises the clip. In the working position, when money tickets are being sorted, the noose is in the lowest position near the smooth pulley.

The feed transport unit 10 (see Fig. 1, 2) consists of three sections that are not connected to each other - two sections of the lower conveyors 55, 56 and one section of the upper conveyor 57. The supporting elements of the conveyors are round endless friction material belts stretched on the driving drums with grooves 58 mounted on shafts and driven drums 59 mounted on axles. The feed transport unit is driven through a double-sided toothed belt 60, which is meshed with the gear pulleys 61, mounted on the shafts of the driving drums and the gear pulley 62, mounted on the shaft of the drive motor 63.

The system for transporting cash tickets 11 (see Fig. 1, 2) consists of a series of sections of the upper and lower conveyors, the supporting elements of which are circular endless belts of friction material, tensioned on the driving drums with grooves 64 mounted on the shafts, and driven drums 65 mounted on the axes, and is used to pass cash tickets sequentially through scanning devices, detectors and nodes monitoring the passage and account. To ensure continuity in the transport system between the scanning devices 12, 13 and the detector, by the definition of magnetic mark 15, the transition from one section to another is carried out on the drum due to the symmetric displacement of the pair of pulling round belts of the next section to adjacent grooves. To ensure synchronization in operation at different parts of the transportation system, the drive is carried out by one double-sided toothed belt 66, which is meshed with toothed pulleys 67, mounted on the shafts of sectional drive drums and toothed pulley 68 of the driving motor 69, which has a speed-stabilizing system. Smooth pulleys 70, mounted on the axles, are designed to give the belt a given direction.

The scanning device for obtaining images of a cash ticket from one split light stream in the visible and infrared regions of spectrum 12 consists of two illuminators of the visible spectrum 71, infrared illuminators 72 and a housing 73 in which the lens 104 (see Fig. 9), a translucent mirror 105, a light filter for highlighting the infrared region of the spectrum 107, a light filter for highlighting the visible region of the spectrum 106, CCD lines 108, electronic devices 109 for capturing images from CCD lines. Information received from the scanning device is processed by a computing unit located in the control unit 22 of the sorting device.

The scanning device for obtaining an image of a money ticket from one split light stream in the infrared region of the spectrum and the induced image obtained by illumination in the ultraviolet region of the spectrum 13 (see Fig. 1) consists of two ultraviolet illuminators 74, an infrared illuminator 2 and a housing 75, in which the lens 104 (see Fig. 10), a translucent mirror 105, a filter for highlighting the infrared region of the spectrum 107, a band-pass optical filter passing the visible part of the spectrum 110, CCD line 108, e electronic devices 109 for capturing images from CCD arrays. Information received from the scanning device is processed by a computing unit located in the control unit 22 of the sorting device.

The ultraviolet detector 14 serves to generate an electronic signal for the control unit of the device, showing the luminosity of the money ticket after lighting it with light in the ultraviolet region of the spectrum and consists of a housing, an ultraviolet illuminator, receivers of reflected light flux with an electronic signal generating unit.

The magnetic tag detection detector 15 (see Figs. 1, 6) is used to generate an electronic signal about the passage of the magnetic tag for the control unit of the sorting device and consists of the upper 76 and lower 77 magnetizing devices, a magnetic probe 78 installed in the guide 79, which together with the carriage 80 moves along two parallel cylindrical racks 81 mounted on a mounting plate. The drive is carried out from an electric motor 82 with a drum 83 fixed to the shaft, on the outer surface of which a string 84 is passed (one turn), fixed at the two ends of the carriage 80. When the motor shaft rotates, the string moves the carriage with the magnetic probe along the racks (in the transverse direction relative to the movement of money ticket).

The control unit of passage and account of cash tickets 16 (see Fig. 1) is used to generate signals for the sorter control unit, indicating the location of specific cash tickets in the path of the movement mechanism and in the path of the supply conveyors of the stacking units (conventional and consist of a light emitter , photodetector and electronic signal generation unit).

The detector for detecting dual money tickets 17 (see Fig. 1) serves to generate electronic signals for the control unit of the sorting device, indicating the detection of dual money tickets in the path of the movement mechanism to exclude them and forwarding to the stacking unit for doubtful money tickets consists of light emitters stream, photodetectors and electronic signal generation unit. The laser detector for detecting the dualism of cash tickets (see Fig. 11) used by us includes a laser sensor and a computational unit 116. The laser sensor consists of an emitter in the form of a laser diode 111, a collimator lens 112, a slit aperture 113, an objective 114, and a photodetector line in the form of a CCD -line 115. The measurement of the thickness of the cash ticket is as follows. The laser beam forms a thin light stroke on the roller, on one or two cash tickets at points A1, B1, C1 (see Fig. 11). They correspond to the image points of the stroke on the CCD line of A2, B2, C2. The distance between the base point of the image position of the light bar A2 and points B2 or C2 is proportional to the measured thickness. The signals from the CCD line are fed to the computing node, in which

- the coordinates of the points of the image of the stroke on the roller, as well as when passing a cash ticket, are remembered;

- the set value of the thickness of the cash ticket is stored;

- calculates the average thickness of one or more banknotes and compares with the specified value.

The separation unit of the flow of cash tickets 18 (see Fig. 1, 7) serves to change the direction of movement of the cash ticket from the main direction - along the path of the movement mechanism towards the stacking unit and consists of two deflecting elements (arrows) 85 mounted on the axis 86, coaxially connected through the clutch 103 with an electric rotary device 87, which when it is turned on, transfers the deflecting elements from the initial lower to upper position by a certain angle.

The units for stacking money tickets 19, 20, 21 (see Fig. 1, 8) have an identical design and consist of inlet conveyors 88, a guide 89, a stacker 90, which is a disk with multi-helical grooves, mounted cantilever on an axis 91 connected through a clutch 92 with an electric motor 93, and a stacking tank 94, in which a cash ticket control device 95 is installed.

The control unit (see Fig. 14) includes

- a controller for generating electronic signals from a magnetic tag detection detector, an ultraviolet detector, a ticket control unit and a cash ticket account, a double ticket detection detector, a cash ticket physical condition monitoring unit, a cash ticket presence monitoring device in the stacking units;

- means for generating an electronic signal of the scanning device for obtaining a visible and infrared image of the scanning device for obtaining infrared and induced images;

- a motion system control unit for receiving information from electronic signal generation means and issuing commands to mechanism control means;

- controls for the mechanisms for driving a cash ticket transportation system, a drive for a feeding transport unit, a drive for positioning rails, a drive for clamping a stack of cash tickets, a drive for adjusting a separating unit, drives for separating cash flow tickets, stacker drives, a drive for moving a probe for a magnetic tag detection detector;

- means for setting operating modes and visualizing the results of the sorting and counting process, consisting of a display, a keyboard and a mouse-type manipulator.

A device for sorting cash tickets works as follows.

The stop of cash tickets 5 is placed in the stop holder of the unit for supplying cash tickets, with the front side of the foot abutting against the stop plate 23, and the base of the foot is placed on the round belts of the conveyor 55 supported by non-drive drums of the feeding unit. With a slight delay in time, in the presence of a stack of cash tickets in the stop holder, the drive of the clamp unit 9 is turned on, lowering the clamp 48 to the upper part of the stack of cash tickets 5. At the same time, the motor 69 starts to accelerate, which drives the main path of the cash ticket transport mechanism 11 .

The electric motor 63 of the conveying transport unit 10, by means of a toothed pulley 62 mounted on a shaft and a double-sided toothed belt meshed with toothed pulleys 61, mounted on the shafts of the driving drums of three sections and the drive shaft of the separating unit, drives round transport belts and friction rings19 separating node, while the direction of movement of the friction rings of the separating node is opposite to the direction of movement of the transport belts. Since the frictional force between the lower cash ticket of the foot and the transport belts is greater than the friction force between cash tickets in the foot, the lower cash ticket is removed by the transport belts from the foot, and the remaining cash tickets are oriented along the profile of the restriction plate 23. The lower cash ticket of the foot moves transport belts and is fed through the gap between the outer surface of the transport belts and the outer surface of the friction rings of the separating node 8. Due to the fact that the adhesion force of the transport p mney slightly higher than the friction rings separating unit, transport belts to feed banknotes have a greater effect than separating ring assembly, whereby the lower cash card is carried further along the piece feeding unit banknotes in booster transport path. The force of interaction of the rings of the separating unit with subsequent cash tickets significantly exceeds the cohesion between adjacent cash tickets, as a result of which all subsequent cash tickets are returned by the rings of the separating unit back to the stack 5. The same happens when filing stuck together, doubled, constructed, etc. cash tickets . Further, the cash ticket passes through the accelerating transport path, consisting of the upper 57 and lower 56 sections. The driving drums of these sections are connected to the drive shafts through overrunning clutches 96. When a money ticket is captured by a receiving roller 97 of the main path of the transportation system, the speed of the money ticket increases due to the difference in speeds between the main path of the transport mechanism and the piece feed path, while the acceleration transport path overrunning clutches account 96 acquires a speed greater than the main speed of the transport belts of the block of piece delivery of cash tickets, where the spatial separation occurs cash tickets on the section of the booster transport tract. Belts of the conveyor move the cash ticket sequentially through the magnetizing device of the magnetic tag detection detector, cash ticket control units and their accounts, an ultraviolet detector, a magnetic tag detection detector, scanning devices; double detection detector and depending on the physical condition, a suitable packing unit or a decrepit ticket packing unit is selected and, accordingly, a flow separation unit corresponding to a given packing unit is turned on, and if it is a dubious ticket, it is sent directly along the main path of the transportation mechanism to a dubious packing unit tickets. In the process of passing money tickets through control nodes, their parameters are checked, for example, images in the visible spectrum and according to aggregate data from electronic signal generation nodes for a given money ticket, the control unit decides in which category this money ticket should be assigned, for example, that this cash ticket is valid. The control unit 22 determines the time the ticket approaches the diverting element 18 of the flow separation unit in front of the packaging unit for valid tickets 19 for its inclusion. When the deflecting element is turned on, the valid ticket is moved by the inlet conveyor of the valid cash ticket stacking unit through the passage control unit and account 16 to the stacker 90, in the form of a disk with multiple helical grooves. Money ticket at the exit of the feed conveyor moves along the guide 89 and enters the spiral groove of the stacker 90, where it slides to the end due to a given momentum and stops. In this case, the stacker rotates and when it reaches the front end of the flat-wall cash ticket, the ticket is removed from the spiral and placed at the bottom of the packing container 94. When the specified number of cash tickets is reached in one of the stacking units suitable or decrepit, the path of the feeding transport unit 10 is turned off, and the stop of the transportation system path 11 occurs after the full run of all cash tickets in the path to the stacking unit of questionable 21. After removal from the stacking unit of a pack of cash tickets (19 or 20), the process of irovki and account automatically renews.

Thus, the invention allows

- increase the reliability of determining the authenticity, dignity and degree of dilapidation of money tickets, since it is not individual points that are analyzed, but a complete image of both sides of the money ticket; - avoid the need to redo the system of sensors (detectors) when switching to a new type of money tickets, which requires time and money funds, because with the claimed method for switching to cash tickets of another country, it is enough to train the software for pattern recognition installed on computing Locke, on new images of cash tickets.
