Description

Portable counterfeit money identification apparatus and counterfeit money identification method using the same {Portable counterfeit money identification apparatus and counterfeit money identification method using the apparatus}

The present invention relates to a counterfeit money identification device and a counterfeit money discrimination method, and more particularly, counterfeit money is firstly identified by a first item, and counterfeit money is firstly discriminated as a counterfeit money in the first discrimination by a second item. It relates to a portable counterfeit identification device that can increase the reliability of counterfeit identification by re-distinguishing true counterfeit money among primary counterfeit money and a counterfeit identification method using the same.

In general, since bills are frequently circulated, they are made of special paper containing about 90% cotton fiber to prevent damage during long-term preservation and distribution, and silver coins to prevent counterfeiting in the paper manufacturing process (hidden picture) , special materials, etc. are inserted into banknote paper.

In addition, as an additional method for counterfeiting prevention, which is realized through special ink or printing method, a method of adding lines to banknotes, a method of using optically variable ink (OVI, Optically Variable Ink) whose color changes depending on the viewing angle , A method of using intaglio printing, which makes a convex tactile feel when touching a specific part, a method of using intaglio latent image, which is clearly visible when viewed from an angle, but does not appear well in a copy, and a method of using an intaglio latent image There are a method of using micro lettering that is not reproduced as it is, and a method of using an optically variable device (OVD) that changes shape or color depending on the viewing angle.

Identification of counterfeit money is performed by determining the presence or absence of anti-counterfeiting means such as the aforementioned magnetic line, optically variable ink unit, latent image unit, and the like.

As a representative method of identifying counterfeit money, there is a method of determining the presence or absence of fluorescent ink used when printing banknotes. The presence or absence of fluorescence is determined by using this because light of a specific visible ray is generated when ultraviolet rays are irradiated on the banknote.

That is, when a banknote is printed with fluorescent ink, ultraviolet rays are irradiated on the banknote and authenticity of the banknote is determined based on whether or not the banknote sample reacts with ultraviolet rays using an optical sensor that reacts to a special wavelength band.

However, there is a disadvantage that the authenticity of the bill cannot be determined unless fluorescent ink is used for bill printing, and even when fluorescent ink is used for bill printing, the authenticity of the bill cannot be determined when fluorescent ink is used for counterfeit bills. there is

On the other hand, even when ultraviolet rays are used for bills, in the above case, authenticity of the bill can be determined, but there is a problem in that the type of bill cannot be identified in addition to authenticity or counterfeit determination.

Another method of identifying counterfeit money is to determine the authenticity of a bill by the presence or absence of a magnetic line. There are downsides to being difficult.

This concludes the description of the configuration of the portable counterfeit money detection device 100.

Hereinafter, a counterfeit money identification method using the portable counterfeit money identification device will be described.

① Step 1: Adjust the width of the bill slot (S100)

Step 1 is a step of adjusting the width of the bill slot 201 according to the denomination of the bill 1 by the width adjusting unit 220 of the portable counterfeit money discrimination device 100 .

In the case of won currency, the width size of the bill slot 201 is not only different for each bill, such as 1,000 won, 5,000 won, and 10,000 won, but also for foreign currencies (dollar, yen, yuan, etc.) Failure to adjust may result in defective entry, which may cause jams or misclassification. Therefore, the size of the bill inlet 201 must be adjusted in advance to match the width of the bill to be identified before discrimination.

② Step 2: Transmission of ticket type selection signal (S200)

Step 2 is a step of selecting a denomination by the denomination selection unit 205 of the portable counterfeit money discrimination device 100 and transmitting the selection signal to the control module 600 when the denomination is selected.

Here, since the control module 600 stores accumulated data for distinguishing the denomination corresponding to the age of use and the degree of damage of the corresponding denomination, it is possible to accurately discriminate denomination even from old or damaged denominations.

In the above description, the user operates the denomination selector 205 to manually select the denomination. However, unlike this, a denomination classification detection sensor (not shown) capable of automatically detecting denomination at the entrance of the bill slot 201. city) can be installed. The denomination sensor detects the width, thickness, etc. of the banknote 1 before the banknote 1 enters the banknote slot 201 and transmits it to the control module 600.

Unlike this, a pattern detection sensor (not shown) for detecting the pattern of the banknote 1 is installed on the discrimination section 203, the bill is moved to the discrimination section, and the pattern is detected by the pattern detection sensor, and the control module It is also possible to transmit to (600).

③ Step 3: Activate item reference value (S300)

Step 3 activates the first item reference value (infrared ray transmission value, ultraviolet transmission value, presence or absence of magnet) and the second item reference value (light transmission reference value at the watermark part) corresponding to the ticket type selection signal transmitted to the control module 600 In this step, since each item reference value is different according to the type of denomination, the item reference value suitable for the type of denomination is activated. As a result, the first and second item reference values corresponding to the corresponding denomination are set.

④ Step 4: 'On' of the first counterfeit money detection module (S400)

Step 4 is a step of 'turning on' the first counterfeit money discrimination module 510 by the first starting unit 206 of the portable counterfeit money detection device 100.

That is, the portable counterfeit money discrimination device 100 according to the present invention has a first start-up unit 206 and a second start-up unit 207, and starts the first counterfeit money discrimination module 510 by selectively manipulating each start-up unit. or the second counterfeit money identification module 520 may be started.

Since this step is primarily for discriminating counterfeit money, the detection value for the first item is derived by 'turning on' only the first counterfeit money discrimination module 510 by operating the first starting unit 206.

⑤ Step 5: 1st detection (S500)

Step 5 transfers the banknote 1 entering the banknote slot 201 to the discrimination section 203 by the transfer module 400, and the first counterfeit discrimination module detects infrared rays, which are primary item values, This is the step of firstly detecting the UV detection value and the presence or absence of a magnet and transmitting the result to the control module 600.

Here, the transfer module 400 is in a stopped state before the banknote 1 is put into the banknote slot 201, and the operation starts only when the banknote 1 is put into the banknote slot 201. To this end, a banknote insertion detection sensor (not shown) is installed at the entrance of the banknote input port 201 to detect that banknotes are being put in, and sends a detection signal to the control module 600 so that the conveyance module 400 at the same time Configurations that enable operation may be applied.

Here, the first counterfeit money detection module 510 is composed of an IR sensor 511, a UV sensor 512, and an MR sensor 513, of which the IR sensor 511 and the UV sensor 512 are reflective type , transmission type or mixed type may be applied.

In the case of the reflective type, the light emitting part and the light receiving part are located in the same direction so that the light irradiated from the light emitting part is reflected on the banknote, and the optical filter selectively selects only infrared rays excluding visible rays or light excluding ultraviolet rays from the light reflected from the banknote. As a configuration in which the light passes through and enters the light receiver, only information on one side of the bill, that is, the front side or the back side, can be obtained.

On the other hand, in the case of the transmission type and the combination type, the light emitting part and the light receiving part are installed opposite to each other with the bill interposed therebetween, and the light emitted from the light emitting part passes through the bill and enters the light receiving part through an optical filter. Since information can be acquired, it is possible to identify counterfeit money more accurately than the reflective type.

In the present invention, any one of the reflection type, transmission type, and combination type can be applied, but it is preferable to apply a transmission type or combination type that is more advantageous for detecting counterfeit lungs.

As described above, the IR sensor 511 is composed of an IR light emitting part 511a and an IR light receiving part 511b, and irradiates red light to the bill, and infrared rays excluding visible light among the light transmitted through the bill. is detected to discriminate the pattern by the special ink used in the bill and at the same time discriminate the fiber pattern contained in the material of the bill. The discrimination value determined in this way is transmitted to the control module 400 to determine whether the banknote is counterfeit.

For example, the IR sensor 511 can determine the location of the hidden line using infrared transmittance passing through the banknote. That is, since the banknote reacts to the infrared light source at a specific location and shows a difference in brightness and darkness, it becomes a criterion for determining the position of the hidden line of the banknote. When the bill reacts to the IR sensor 511, the location of the silver line indicates a high current of 3V, and the location other than the silver line indicates a low current of 1V, so that the position of the hidden line of the banknote can be grasped. If the hidden line is not detected, it is counterfeit.

The UV sensor 512 is composed of a UV light emitter 512a and a UV light receiver 513a, radiates ultraviolet rays to a corresponding bill, and detects an ultraviolet transmittance value penetrating the bill. The detected data is sent to the control module 600 to determine whether counterfeiting or not.

The UV sensor 512 irradiates light in the UV range of 360 to 400 nm on non-fluorescent paper and fluorescent paper, for example, ultraviolet rays having a peak of 393 nm, respectively, and the non-fluorescent paper has a peak wavelength of 393 nm and a wavelength of up to 440 nm On the other hand, it uses a phenomenon in which the 441nm peak wavelength together with the UV 393nm peak wavelength appears as high intensity when fluorescent paper is irradiated. In other words, when UV light is irradiated on counterfeit lungs based on fluorescent paper, a wide range of light from 440 to 600 nm is generated with a peak at 441 nm, while a small amount of light up to 440 nm is emitted in non-fluorescent paper based counterfeit lungs. It uses the principle that the wavelength appears and the 440~600 nm wavelength range rarely occurs, making it possible to distinguish between pneumoconiosis and counterfeit lungs.

The MR sensor 513 detects the presence and strength of the magnetic component of the magnetic ink printed on the bill 1 and sends it to the control module 600, so that the control module detects counterfeit bills that do not match this item It is to do.

⑥ Step 6: 1st counterfeiting and return (S600)

Step 6 compares the first detection value sent to the control module 600 with the first item reference value to discriminate whether or not the bill 1 is counterfeit, and as a result of the discrimination, the first detection value is the first item reference value. If it is within the range, it is judged to be a real bill and conveyed to be discharged to the bill outlet 202, and when the first detection value is outside the range of the first item reference value, it is determined to be counterfeit bill, This step is to drive the conveyance module 400 in reverse according to the step so that the bill is conveyed backward to the slot 201 .

On the other hand, in order to find a parameter with a large difference in dominance between the pneumoconiosis area and the counterfeit lung area in the discrimination of counterfeit lung by the UV sensor 512, a combination with a large difference in dominance between the pneumoconiosis area and the counterfeit lung area was selected through a total of 243 experiments.

1) Experiment conditions

- Laboratory standard conditions: similar to normal temperature and humidity conditions

- Equipment used for the classification test of pneumoconiosis samples (optical analyzer)

Analyzer: Spectro Photometer

Model:PU8800 UV/VIS SPECTRO PHOTOMETER

Maker:Philips

2) Pneumoconiosis samples

- Classified into 3 types (new right, distribution right, damaged right) by optical analyzer

- Total of 12 types, 10 each -> Total of 360 (old: $1, $2, $5, $10, $20, $50, $100) (new: $5, $10, $20, $50, $100)

- Pneumoconiosis was classified as follows based on reflectance by wavelength using an optical analyzer (Philips PU8800 UV/VIS Spectro Photometer).

3) counterfeit money sample

- Counterfeit money is classified as follows.

4) Experiment method

a) Combination of experimental parameters

The number of experiment combinations with the number of experimental factors 5 and the number of levels for each factor 3 is a redundant permutation that allows 3 levels of overlap under one condition and arranges 5 factors, resulting in a total of 3Π5 = 243 experimental combinations.

Wavelength range of light source (W) (W1, W2, W3)

Light source intensity (P) (P1, P2, P3)

Distance between the light source and the bill face (D) (D1, D2, D3)

Distance between the light emitting part and the bill face (d) (d1, d2, d3)

Filter (F) of light receiving part, 3 levels each (F1, F2, F3)

*243 experiments under WaPbDldmFn conditions

b) Criteria for processing data

360 notifications of pneumoconiosis samples selected in any combination,

The number of counterfeit samples notified is 60 (counterfeit samples are limited to the number of purchases and are mainly for medium and high denominations), and the average output value of 10 sheets per same denomination is recorded. sum the outputs.

Values of abnormal data (values outside the range of 5∂ of the average output value of a group) are not included.

[Table 1]

[Table 1] above is the digital measurement value by the equipment (optical analyzer) used for the classification test of the pneumoconiosis sample. The larger the value, the closer it is to pneumoconiosis, and the smaller the value, the closer it is to counterfeit money.

Here, the optimal experimental combination is, W ₃ = wavelength of the UV light source in the UV light emitting part 375 nm,

P ₂ = UV light source intensity 1 nm,

D ₁ = 4.5mm distance between UV light source and banknote face;

dm = 2.6mm distance between UV light receiver and bill face,

F ₁ = UV light receiver optical filter (Ffilter) = U360.

According to the experimental combination described above, a combination with a large difference between the pneumoconiosis area and the counterfeit area was selected, and as a result, the digital measurement values shown in [Table 1] show that the boundary between the pneumoconiosis and the counterfeit area is clear. However, among the counterfeit bills, small denominations ($1, $2, $5, $10, $20) were excluded from the experiment in consideration of the fact that the higher the denomination, the more likely it is to be counterfeit.

5) Test results and meaning

a) Experimental results

From a total of 243 experimental combinations (experiment period: 6 months), a combination with a large difference in dominance between the pneumoconiosis area and the false lung area was selected, and the limits of each parameter were determined accordingly, and the deviation of the result values even in 10 experiments under the same conditions Since it was shifted within the range of standard deviation, the reproducibility of the experimental results was proven, and the detection ability was improved compared to the existing counterfeit lung detector.

Therefore, based on the results of this experiment, the standard characteristics of the fiber array recognition light receiver apply the 3-fold interval (3∂) of the standard deviation corresponding to the 99.7% area in the normal distribution, and the reference characteristic value of the fiber array recognition light receiver = 13602±3∂ The area of is defined as the pneumoconiosis area.

⑦ Step 7: 'On' of the 2nd counterfeit money identification module (S700)

Step 7 is a step of 'turning on' the second counterfeit money discrimination module 520 by the second starting unit 207 of the portable counterfeit money discrimination device 100.

That is, the portable counterfeit money discrimination device 100 according to the present invention has a first start-up unit 206 and a second start-up unit 207, and starts the first counterfeit money discrimination module 510 by selectively manipulating each start-up unit. or the second counterfeit money identification module 520 may be started. In this step, since counterfeit money is discriminated secondarily, by operating the second starting unit 207, only the second counterfeit money discrimination module 520 is 'on' to derive a detection value for the secondary item.

⑧ Step 8: Secondary detection (S800)

In step 8, the first counterfeit money determined to be counterfeit according to the first reading result is re-entered into the bill inlet 201 and re-transferred to the discrimination section 203 by the conveying module 400 so as to detect the optical sensor 521. This is a step of secondarily detecting the light transmission value (secondary detection value) at the watermark part of the banknote and sending it to the control module 600.

⑨ Step 9: 2nd counterfeiting and return (S900)

Step 9 compares the second detection value transmitted to the control module 600 with the reference value of the second item to read whether the first counterfeit money is counterfeited again, and the second detection value is the category of the reference value of the second item. If it is within the first counterfeit judgment, it is judged to be corrected as pneumatic currency despite the first counterfeit determination, and the control module 600 drives the transfer module 400 forward to take it out to the bill outlet ( ), and the second detection value is the second item reference value. If it is out of the range, it is determined as final counterfeit bill, and the transfer module 400 is driven backward according to the control signal of the control module 600 so that the bill is transferred back to the bill slot 201.

In other words, if pneumoconiosis is determined by the primary detection, pneumoconiosis is determined without a re-examination, whereas if it is determined to be counterfeit, the above-described secondary discrimination process is performed without being determined as counterfeit. The purpose of the secondary identification is to take into account that even if it is first determined to be counterfeit money, it may be misdiagnosed as counterfeit money because the expiration date is old or severely damaged during counterfeit money. there will be
