Description

[0001] The present invention relates to a method and apparatus for distinguishing a pocket security,

More particularly, the present invention relates to a method and an apparatus for counting 2 CIS 1 pocket securities.

In general, the 2CIS 2 pocket bill counter is widely used as a device for discriminating and counting bills. That is, when the banknote is inserted into the input port, two contact image sensors (CIS) detect the front and back sides of the banknote to count the banknotes, recognize the serial number printed on the banknote, The banknotes discriminated from whether or not the banknotes are falsified are output to the first pocket corresponding to the first outlet and the abnormal banknotes are output to the second pocket corresponding to the second outlet.

However, the 2CIS 1 pocket bill counter uses two CISs and outputs bills in one pocket. However, in the one-pocket type discharge processing, the length of the path of the banknote which is inserted into the input port and discharged to the pocket corresponding to the discharge port is not more than half the length of the two-pocket type, so that the time from input to discharge of the banknote is two- . The length of the banknote movement path is a restriction condition that the counting and discrimination time of the banknote must be very short.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a bill counting system and a configuration for discriminating paper currency of a 2CIS 1 pocket type paper currency discrimination counting apparatus. Referring to FIG. 1, when a banknote is input through an input port, if the first CIS 102 senses the front (or rear) of the banknote by the second CIS 106 and generates the analog electric signal, And outputs it as a digital image signal through the A / D converters 104 and 108.

The image acquisition unit 110 stores the digital image signal in the memory 112 in the form of the image data via the first data bus. The processor 120 reads the image data of the paper money stored in the image obtaining unit 110 to classify the denomination, discriminate whether or not the document is forged, recognize the serial number of the paper money, and recognize the bar code.

FIG. 2 is a timing chart for acquiring and discriminating the bill data of the 2CIS 1 pocket bill counter. The bill counting and discrimination should be handled within one count cycle by the bill counter sensor.

2, the time at which the image acquisition unit 110 stores the image signal output from the 2CIS in the form of image data in the memory 112 and the time at which the processor 120 stores the image data stored in the image acquisition unit 110 The time for reading the bill and the bill discrimination time are added, the time for discriminating one bill is counted and exceeded. That is, the next banknote is inserted and collision occurs before the inputted banknotes are discriminated and outputted.

This is a problem caused by insufficient data processing time due to a large amount of sensed data because 2CIS is used. That is, the data processing speed of the image obtaining unit 110 and the processor 120 is slow and a collision occurs. In order to solve this problem, high-speed and high-priced components can be solved to some extent, but this is not economical due to high manufacturing cost. Therefore, there is a need for a technique capable of increasing the processing speed without using expensive parts.

FIG. 3 is a block diagram of an embodiment of a configuration of a 2 CIS1 pocket securities discrimination and counting apparatus according to the present invention. The 2 CIS1 pocket security differential counting apparatus according to the present invention includes a CIS unit 300, an image data obtaining unit 310, a program storage unit 330, and a processor 320. [

The CIS unit 300 simultaneously senses both sides of the securities by the two CISs 302 and 306 disposed at the input port of the securities, and converts the securities image signal into digital signals.

The image data acquiring unit 310 controls the CIS unit 300 to convert the image signal of the security converted into the digital signal into first resolution visible light image data, second resolution visible light image data higher than the first resolution, Resolution infrared (IR) image data and the third resolution transmission infrared (IR) image data and stores the data in a memory (not shown). The first resolution, the second resolution, the third resolution, and the fourth resolution can be variously determined, and the present invention is not limited by the numerical values of the resolution. In an embodiment of the present invention, the first resolution, the second resolution, the third resolution, and the fourth resolution are related to each other, the second resolution is higher than the first resolution, and the third and fourth resolutions are lower than the first resolution . For example, the first resolution may be 25x33 DPI, the second resolution may be 100x100 DPI, and the third and fourth resolutions may be 25x17 DPI. Hereinafter, for convenience of description, the first resolution visible light image data is 25x33 visible light data, the second resolution visible light image data is 100x100 visible light data, the third resolution reflection infrared image data is 25x17 reflection IR data, the fourth resolution transmission infrared image data is 25x17 Transmission IR data.

Here, the 25x33 visible light data, the 25x17 reflection IR data, the 25x17 transmission IR data, and the 100x100 visible light data can be generated as follows.

The apparatus for discriminating securities having one pocket according to the present invention is characterized in that when the securities are inputted through the input port of the securities and are discriminated and counted into one pocket and the securities are discharged, An LED is provided, and visible light data and infrared (IR) data can be generated while selectively performing on / off operation in a time division manner. Specifically, when the visible light LED is turned on, 25x33 visible light data on both sides (front and rear) and 100x100 visible light data on both sides (front and back) are acquired and when the transmission infrared LED is turned on, both sides (front and back) . And when reflective infrared LED is ON, it obtains 25x17 reflection IR data on both sides (front and back). That is, each of the visible light 25x33 and 100x100 has four data on the front side and four data on the back side, respectively.

On the other hand, the program storage unit 330 stores programs for discriminating denomination, forgery and discrimination, and for identifying serial numbers and bar codes.

The processor 320 reads the image data of the securities stored in the image data obtaining unit 310 and classifies the denomination of the securities by executing the denomination classification, counterfeit discrimination, serial number and barcode discrimination program, , Serial number, and bar code.

The program 332 for denomination classification detects the four vertices of the securities using the 25x33 DPI visible light data of one of the generated 8 sides of securities data to calculate the size of the securities, A command for selecting at least one brand-name candidate corresponding to the size of the stock, a command for encoding the 25x33 visible light data of the generated stock, and at least one pre-stored model corresponding to the selected at least one class And comparing the master data for discrimination with the 25x33 visible light data of the encoded securities to determine a securities corresponding to master data having a matching rate equal to or higher than a threshold as the denomination of the inputted security.

The command for encoding the 25x33 visible light data of the securities constituting the denomination classification program 332 is to obtain block data of a certain size based on each of the detected four vertices from the 25x33 visible light data of the securities, Instructions for generating data of the pre-coding stage by reducing the data size for each of the obtained block data, and instructions for coding the data of the pre-stage coding stage. At this time, the master data for identifying the denomination discrimination block data of the predetermined size is generated in the same manner as the method of generating the pre-encoding data from the 25x33 visible light data of the security on the basis of each of the four vertices of the securities, The data size can be reduced for each of the pre-encoding data, and the pre-encoding data can be generated.

The serial numbers and programs for identifying the bar codes 336 and 338 are used to identify serial numbers and bar codes from the securities for which the denomination has been determined when a denomination of the securities is determined, an instruction for obtaining the area in which the bar codes are located, A command for obtaining the corresponding data from the 100x100 DPI visible light image data, and a command for identifying the serial number and barcode of the security using the obtained serial number and data of the barcode area .

The program 334 for discriminating counterfeit money includes instructions for obtaining the 25x17 DPI reflection IR data and the 25x17 transmission IR data for at least one predetermined region of the denominated security and the obtained 25x17 reflection IR data And 25x17 transmission IR data and master data for fake discrimination of the discriminated securities. If the coincidence rate is equal to or greater than the threshold, it is determined that the coincidence rate is normal. If the coincidence rate is less than the threshold value, it is determined that the coincidence rate is falsified.

FIG. 4 is a block diagram showing an example of a more detailed configuration of the 2 CIS1 pocket security discrimination counting apparatus of the present invention shown in FIG.

4, the 2 CIS1 pocket securities discrimination and counting apparatus of the present invention includes a first CIS unit 400, a second CIS unit 410, a first image obtaining unit 420, a second image obtaining unit 430, A processor 440, and a program storage unit 450.

The first CIS unit 400 includes a first CIS 402 and a first ADC 404. When the securities are input through the securities input port, the first CIS 402 transmits the securities The first ADC 404 converts the analog image signal generated by the first CIS 402 into a digital signal and outputs the digital signal.

The second CIS unit 410 includes a second CIS 412 and a second ADC 414. When the securities are input through the securities input port, the second CIS 412 scans the other side of the securities, And generates an image signal. The second ADC 414 converts the analog image signal generated by the second CIS 412 into a digital signal and outputs the digital signal. It is preferable that the first CIS 402 and the second CIS 412 are located as close as possible in order to closely monitor securities. In the embodiment of the present invention, the processing speed is increased by separating one piece of securities into two sections. When a security is detected by a contact image sensor and is counted and discriminated, a single security is divided into two sections: a main image section and a subsequent image section. The first image obtaining unit 420 stores the digital image signal generated in the main image period in the form of main image data and outputs the image data of the stored main image period according to the output control signal generated in the processor 440 A first control unit 422, and a first memory 424.

The first memory 424 senses an image of the main image section and stores the output digital signal as data. The first control unit 422 stores the digital image signals output from the first CIS unit 400 and the second CIS unit 410 in the first memory 424 in the form of main image data under the control of the output control signal . To this end, the first control unit 422 generates an address of the memory. The first controller 422 allows the processor 440 to read the main image data stored in the first memory 424 when the image data of the main image section is stored in the first memory 424.

When the image of the main image section is stored in the first memory 424 as main image data by the first image acquiring section 420, the second image acquiring section 430 acquires the next image signal of the next image section And outputs the stored subsequent image data by the output control signal, and includes a second control unit 432 and a second memory 434. [

The second memory 434 stores the image of the subsequent image section as data that can be output to the processor 440.

The second control unit 432 controls the first image obtaining unit 420 (among the digital image signals of the first CIS unit 400 and the second CIS unit 410) generated for one security by the control of the output control signal When the image of the main image section is stored in the first memory 424 as data that can be output to the processor 440, an address may be generated to allow the processor 440 to read the image of the subsequent image section To be stored in the second memory 434 as a data format. When the storage of the subsequent image data is completed in the second memory 434, the processor 440 causes the main image data stored in the second memory 434 to be output.

The processor 440 generates the output control signal for controlling the data input / output of the first image acquiring unit 420 and the second image acquiring unit 430. The processor 440 receives the image data of the main image section and the image data of the subsequent image section output from the first image acquiring section 420 and the second image acquiring section 430, And the bar code.

The program storage unit 450 stores a denomination classifying program 452, a counterfeit discriminating program 454, and programs 456 and 458 for identifying a serial number and a bar code. The description of the denomination classifying program 452, the counterfeit discriminating program 454 and the programs for identifying the serial number and the barcode 456 and 458 are the same as those of the denomination discriminating program 332, the counterfeit discriminating program 334 and the serial number And the programs 336 and 338 for barcode identification are omitted.

The first image acquiring unit 420 and the second image acquiring unit 430 perform data input / output at different times according to the output control signals. In the embodiment of the present invention, the image data output of the main image section of the first image obtaining section 420 and the image data storage of the subsequent image section of the second image obtaining section 430 are processed in parallel. That is, when the first image obtaining unit 420 outputs the main image data to the processor 440, the second image obtaining unit 430 may simultaneously store the subsequent image data in the second memory 434. [

The first image acquiring unit 420, the second image acquiring unit 430 and the processor 440 are connected to the input unit through a start signal START Start operation. The processor 440 uses the signal generated by the encoder 490 so that the output control signal C / S is applied to the first image acquisition unit 420 and the second image acquisition unit 430 via the first data bus 460 And the second data bus 470 are enabled.

4, the first image obtaining unit 420 and the second image obtaining unit 430 are connected to the first CIS unit 400 and the second CIS unit 410 via the first data bus 460, And is coupled to the processor 440 via a second data bus 470.

The output control signal is also used as a signal (C / S) in which the processor 440 selects the first image obtaining unit 420 and the second image obtaining unit 430, and when the image signal is stored as image data from the CIS The right to use the first data bus 460 can be determined. When the processor 440 reads the security image data stored in the first image acquiring unit 420 and the second image acquiring unit 430, the first image acquiring unit 420 and the second image acquiring unit 430 ) Of the second data bus.

Table 1 shows the usage rights of the first data bus 460 and the second data bus 470 of the first image acquiring unit 420 and the second image acquiring unit 430 according to the output control signal.

In an embodiment of the present invention, the processor 440 controls the first data bus 460 and the second data bus 470 of the first image acquiring unit 420 and the second image acquiring unit 430 using the output control signal. ) You can control the license. Since the first data bus 460 is shared by the first image acquiring unit 420 and the second image acquiring unit 430, the first image acquiring unit 420 and the second image acquiring unit 430 Section 430 can not use the first data bus 460 at the same time. That is, if the first image obtaining unit 420 is using the first data bus 460, the second image obtaining unit 430 can not use the first data bus 460. Similarly, if the second image acquiring unit 430 is using the first data bus 460, the first image acquiring unit 420 can not use the first data bus 460.

Since the second data bus 470 is also shared by the first image acquiring unit 420 and the second image acquiring unit 430 when the processor 440 reads data, 2 image acquisition unit 430 can not use the second data bus 470 at the same time. That is, if the processor 440 is using the second data bus 470 to read the data of the first image acquiring unit 420, the second image acquiring unit 430 acquires the second data bus 470 Data can not be output through the. Similarly, if the processor 440 is using the second data bus 470 to read the data of the second image acquiring unit 430, the first image acquiring unit 430 may be connected to the second image acquiring unit 430 via the second data bus 460 Data can not be output.

FIG. 5 is a timing chart showing timings for acquisition and discrimination of securities image data of the 2 CIS 1 pocket security counter device according to the present invention.

FIG. 6 is a flowchart illustrating an embodiment of the 2CIS 1 pocket securities discrimination counting method of the 2CIS 1 pocket securities discrimination counting apparatus according to an embodiment of the present invention.

3 to 6, a description will be made of an embodiment of the 2 CIS 1 pocket security discrimination counting method of the 2CIS 1 pocket securities discrimination counting apparatus according to an embodiment of the present invention.

Referring to FIG. 5, the present invention should process counting and discrimination of securities generated through 2 CIS within one cycle of a counting clock, that is, a processing time of one security.

To this end, both sides of a security in which the two CISs 302 and 306 disposed at the input port are sensed simultaneously to generate visible light data of both the first and second resolution (front and back) and visible light data of the second resolution (front and back) (Step S600). In this embodiment, the first resolution visible light data uses 25x33 DPI visible light image data, and the second resolution visible light data uses 100x100 DPI visible light image data.

The four corners of the security are detected using the visible light data of the front side of the first resolution (25x33) or the backside visible light data among the generated security data to calculate the size of the security (S610)

At least one reel number candidate corresponding to the calculated size of the securities is selected (step S620)

The front side or back side visible light data of the first resolution (25x33) of the generated security is encoded (step S630)

The master data corresponding to at least one denomination thus obtained is compared with the data of the encoded securities (step S640), and the securities corresponding to the master data having the matching rate equal to or higher than the threshold value are compared with the inputted oil price (Step S650)

7A and 7B illustrate a process of encoding the visible light image data of the first resolution (25x33) in order to discriminate the denomination of securities. Referring to FIG. 7, in step S630, (25x33) front visible light data encoding will be described in more detail. Four vertexes of the security are detected from visible light data at the first resolution (25x33) of the security. And acquires block data of a predetermined size based on each detected vertex. FIG. 7A is a block 710, 720, 730, and 740 of a predetermined size for discriminating a reel type on the basis of a vertex in a securities class having a large size. Each of the blocks 710, 720, 730, 740 is shown as four for convenience but may be a larger number of blocks. For example, it is possible to make 14x6 blocks based on each vertex, and since one vertex has four vertexes, (14x6) x4 (= 336) block data can be generated.

FIG. 7B shows blocks 760, 770, 780, and 790 of a predetermined size based on the vertices in a small-sized securities market. Each of the blocks 760, 770, 780, 790 is shown as four for convenience and shows that there are overlapping parts.

In the present invention, the data size of each of the blocks is reduced, and the generated pre-encoding data is encoded. For example, each block may be represented by one byte, i.e., represented by 256 data, but it may be reduced to 32 data instead of 256 data to reduce the data size.

On the other hand, overlapping portions may be included regardless of the size of securities. In other words, a large-size security does not overlap with a certain size and number of blocks on the basis of four vertexes, but a small-sized securities has the same number of blocks as the large securities, have.

In this way, all securities are encoded by reducing data of the same size and number of blocks to generate one-dimensional array of encoded data, whereby the denomination of securities can be discriminated by using small-sized data. Since the size and the number of the blocks are the same regardless of the denomination of each of the four vertices, the blocks are not overlapped with each other on the basis of each vertex as shown in FIG. 7A, The blocks are overlapped when blocks having the same size and the same number are generated in the process of generating a block based on the vertices as shown in FIG. 7B. However, this method is effective for searching for a desired model in a short time in many cube processing. In FIG. 7B, a small security is shown, and block 760 and block 770 are overlapped, and block 780 and block 790 are overlapped.

In this process, the data of the first resolution (25x33) of the securities to be discriminated by the denomination is encoded, and then the encoded data is compared with the master data for distinguishing denomination obtained beforehand for each denomination of securities, Master class is discriminated through master data corresponding to high. The master data for identifying the denomination is also data encoded in advance in the same manner as the encoded data size of the first resolution front side (25x33) visible light data. If there are two types of prize candidates, there are two master data to be compared because there are master data for each candidate type, and if there are n, there are also n master data to be compared.

If it is determined that the coinage rate is equal to or higher than the threshold value, the master device obtains the area where the serial number and the barcode are located from the securities for which the denomination has been determined (step S660)

Data corresponding to the area where the serial number and the bar code are located is obtained from the second resolution (100x100) visible light data (step S670)

The serial number and barcode of the security are identified by the obtained second resolution (100x100) data (step S680)

Meanwhile, FIG. 8 is a flowchart showing an example of a method for discriminating whether a security is counterfeited or not. In order to discriminate whether or not the securities are counterfeited, the step S600 simultaneously senses both sides of the securities to which the two CISs disposed at the input port are sensed, thereby obtaining the third resolution two-sided (front and back) reflection IR data, (S800). In the example of the present invention, the third resolution and the fourth resolution use 25x17 DPI.

(Front and back) visible light data, the third resolution 25x17, the both-side (front and back) reflection IR data, the fourth resolution 25x17, and the first and second resolutions 25x17 and 25x17 in the step S600 of FIG. (Front and back) transmission IR data and second resolution (100x100) Both sides (front and back) visible light data generation can be done as follows.

The apparatus for discriminating securities having one pocket according to the present invention is characterized in that when the securities are inputted through the input port of the securities and are discriminated and counted into one pocket and the securities are discharged, An LED is provided, and visible light data and infrared (IR) data can be generated while selectively performing on / off operation in a time division manner. Specifically, when the visible light LED is turned on, visible light data on both sides (front and back) of the first resolution (25x33) is acquired, and visible light data on both sides (front and back) When the third resolution (25x17) Obtained the IR data on both sides (front, back). When the transmission infrared LED is turned on, the second resolution (25x17) of both sides (front and back) transmission IR data is obtained.

The discrimination as to whether or not the image is counterfeit using the third resolution (25x17) reflection IR data and the fourth resolution (25x17) transmission IR data can be performed as follows.

First, the third resolution (25x17) reflection IR data and the fourth resolution (25x17) transmission IR data for at least one predetermined region of the denominated securities are obtained (S810) 3 resolution (25x17) reflection IR data and the fourth resolution (25x17) transmission IR data with the master data for counterfeit determination of the discriminated securities (step S820), checking whether the coincidence rate is equal to or greater than the threshold value (step S830) If the match rate is equal to or greater than the threshold value, it is determined to be normal security (step S840). If the match rate is less than the threshold value, it is determined to be forged securities (step S850)

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
