Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 illustrates an embodiment of the configuration of a portable counterfeit detection apparatus according to the present invention, which shows the outside of a portable device that can detect whether the bill forgery.

The portable counterfeit detection device 10 includes an infrared (IR) sensor, an ultraviolet (UV) sensor, a magnetic (MG) sensor, an ultrasonic (US) sensor, a CIS sensor, and the like, for detecting various counterfeit elements formed on the bill. It is a device that can detect whether the banknotes are forged as the proximity of one side of the counterfeit element is formed.

The portable counterfeit detection apparatus 10 according to an embodiment of the present invention includes an anti-stoke sensor for detecting an anti-Stokes material formed in a specific region of a bill for detecting counterfeit.

First, Stokes' shift refers to a phenomenon in which a special material absorbs a photon and emits a photon having a wavelength spectrum different from that. Specifically, when a material composed of molecules or atoms absorbs a photon, energy is obtained. When the energy saturation state is released to have the original energy to emit again, when the energy of the emitted photons is less than the energy of the absorbed photons is called the Stokes shift phenomenon.

Anti-Stokes' shift, on the other hand, is a case where the energy of photons emitted is greater than the energy of photons absorbed, as opposed to the Stokes shift phenomenon, for example, infrared light having a wavelength of about 900 nm or more. If this is absorbed it may mean a phenomenon that is emitted by the visible light having a smaller wavelength and transition.

In other words, the anti-stork material is a material capable of emitting light in the visible range when excited by infrared (IR), and the rotation line of the Raman spectrum is called a Raman line, and the line appearing at a wavelength longer than the incident light is called a stokes line, a short wavelength. The line that appears on the side is called the anti-stokes line.

The Raman spectrum is a spectrum of scattered light due to the Raman effect. The Raman spectrum is referred to as a vibration Raman spectrum when an energy difference between the incident photons and a molecule is exchanged between the vibrational levels of molecules in a ground state.

In this case, since the transition between the rotational levels is also related, it is also called a Raman rotational vibration band, and the vibration quantum number is strongly changed by one. On the other hand, the spectrum in the case where the transmission and reception of energy differences between rotation levels within the lowest vibration level in the ground state occurs is called the rotational Raman spectrum.

Referring to FIG. 1, a light source 110 for emitting infrared light and a sensor 120 for detecting light emitted from the banknote 50 may be provided at an end of the portable counterfeit detection device 10.

As described above, the light source 110 may allow infrared light to be irradiated to a specific area of the bill 50 using an LED emitting infrared light, and the specific area of the bill 50 is an anti-stoke as a counterfeit element. (Anti-Stokes) It may be an area where the material 55 is printed.

Meanwhile, the sensor 120 may detect visible light emitted from the infrared light emitted from the light source 110 after being absorbed by the anti-stoke material 55 printed on the banknote 50.

It is determined whether the banknote 50 is forged using the visible light detected by the sensor 120, and a notification for indicating a result of the counterfeit determination may be provided to the user by the portable counterfeit detection apparatus 10. .

For example, when the user places the portable counterfeit detection device 10 in close proximity to an area where the anti-stoke material 55 of the banknote 50 is formed, and then presses the operation button 130, the light source 110 may emit infrared light. The sensor 120 may operate to detect visible light emitted from the anti-stoke material 55 printed on the banknote 50.

In addition, the speaker 140 provided in the portable forgery detecting apparatus 10 may output a notification sound according to a result of the forgery determination based on the detected visible light.

2 is a block diagram illustrating a simplified configuration of a portable gasoline detecting device according to an embodiment of the present invention. The portable gasoline detecting device 10 illustrated in FIG. 2 includes a user input unit 210, an output unit 220, and a power supply unit ( 230, the controller 240, the light emitter 250, the light receiver 260, and the counterfeit determination unit 270. Description of the same elements as those described with reference to FIG. 1 among the components of the portable gasoline detection device shown in FIG. 2 will be omitted below.

Referring to FIG. 2, the user input unit 210 generates input data for controlling the operation of the portable counterfeit detection device 10 by using a button, a keypad, a dome switch, and the like. switch), a touch pad (constant voltage / capacitance), a jog wheel, a jog switch, and the like.

For example, the user input unit 210 may include an operation button 130 described with reference to FIG. 1 to turn on / off power supply to the light emitting unit 250 and the light receiving unit 260 according to a user's pressing operation. have.

The output unit 220 may provide a notification for indicating a result of the counterfeit determination, and may include a display module, a sound output module, or a haptic module to generate an output related to visual, auditory, or tactile.

For example, the output unit 220 may include the speaker 140 described with reference to FIG. 1 to output a notification sound indicating a counterfeit determination result.

The power supply unit 230 receives an external power source or an internal power source under the control of the controller 240 to supply power for operation of each component.

For example, the power supply unit 230 may include a battery for power supply, and the battery may be disposable or rechargeable.

Meanwhile, the light emitting unit 250 uses infrared light emitting diodes (LEDs) to emit infrared light. The light emitting unit 250 emits infrared light in a specific area of the bill (for example, an area where anti-stoke material is formed on one side of the bill). Light may be irradiated.

For example, the light emitter 250 may irradiate infrared light having a wavelength of about 930 nm to 1040 nm to a region where an anti-stoke material is formed on one surface of the banknote.

The light receiver 260 may detect visible light emitted from the anti-stokes material after the infrared light emitted by the light emitter 250 is absorbed by the anti-stokes material formed on the banknote.

In addition, the counterfeit judging unit 270 determines whether the paper money is forged by using the visible light detected by the light receiving unit 260, and after indicating whether the counterfeit is counterfeit through the output unit 220. Notifications can be delivered to the user visually, acoustically, or tactilely.

For example, the counterfeit judging unit 270 may determine whether the banknote is forged based on a voltage or a current corresponding to the size of visible light detected through the light receiving unit 260.

On the other hand, the control unit 240 serves to control the overall operation and functions of each component of the bill detection apparatus as described above.

3 is a flowchart illustrating a counterfeit detection method according to an embodiment of the present invention. The block diagram showing the configuration of the portable counterfeit detection apparatus according to the embodiment of the present invention shown in FIG. The description will be made in conjunction.

Referring to FIG. 3, first, when a user moves the portable counterfeit detection apparatus 10 to a region where anti-stoke material is formed on one side of a bill, the light emitting unit 250 may use an LED that emits infrared light. The banknote is irradiated with infrared light (step S300).

For example, as illustrated in FIG. 4, the light emitter 250 emits infrared light having a wavelength of 930 nm to 1040 nm using the infrared LED 251, and uses the convex lens 253 to emit light. Diffuse to increase the width of the light emitted so that the infrared light is irradiated on one surface of the bill (50).

The light receiving unit 260 detects visible light generated from the bill by infrared light emitted by the light emitting unit 250 (S310).

As described above, the visible light detected through the light receiver 260 may be emitted after the infrared light irradiated onto the bill 50 is absorbed by the anti-stoke material formed on the bill 50, and may be 380 nm or more. It may have a wavelength of 800 nm.

For that purpose, the light receiving unit 260 may include a visible light filter 261 for filtering light having a wavelength of 380 nm to 800 nm and a light receiving sensor 263 for receiving light filtered through the visible light filter 261. Can be.

Thereafter, the counterfeit judging unit 270 determines whether the banknote is forged using the visible light detected through the light receiving unit 260 (step S320).

For example, when the light emitting part 250 and the light receiving part 260 of the portable counterfeit detection device 10 are close to a specific area of the light emitting module 430 and the bill 50, Infrared light is generated without any reaction, and visible light is generated in a region where anti-counterfeiting ink containing an anti-stoke material is formed in the banknote 50, so that an optical signal or light is transmitted to the light receiving unit 260, and the amount of current is equal to the amount of light. Alternatively, the voltage may be expressed, and the presence or absence of the anti-stoke material may be determined by measuring the voltage or current expressed, and the value of the anti-stoke material may be determined.

After the determination of whether or not the counterfeit bill in step S320 is completed, if the bill is not a counterfeit bill (step S330), the output unit 220 outputs a pneumatic confirmation sound using a speaker (step S340).

In the above, the output unit 220 has been described as an example of detecting the pneumoconiosis according to the present invention, but the present invention is not limited to this, the present invention is not limited to this, the output of a warning sound, or the result of the determination of the counterfeit color or It can also be displayed using text.

On the other hand, as shown in Figure 4, the light emitting unit 250 and the light receiving unit 260 is provided in a reflective structure at the end of the portable counterfeit detection device 10, the light receiving unit 260 is reflected from the bill 50 The light emitting unit 250 may be positioned on the same side as the light emitting unit 250 to detect light.

Hereinafter, with reference to FIGS. 5 to 8 will be described an embodiment of a method for detecting forgery using an anti-Stokes material formed on the bill.

Referring to FIG. 5, a user may first approach the portable counterfeit detection device 10 to the counterfeit element region 510 in which anti-stoke material is formed on one side of the banknote 500, and then press the operation button 130. .

At this time, the light emitting unit 250 and the light receiving unit 260 of the portable counterfeit detection device 10 start to operate, and the light receiving unit 260 is formed from the anti-stokes material formed in the counterfeit element region 510 of the banknote 500. Detecting visible light is emitted, the counterfeit determination unit 270 may determine whether the counterfeit bill by checking whether the voltage or current corresponding to the size of the detected visible light is greater than a predetermined reference value.

In the case shown in FIG. 5, when the banknote 500 is not forged, the visible light generated from the counterfeit element region 510 of the banknote 500 is detected by the light receiving unit 260 above the set value, Accordingly, the speaker 140 of the portable gasoline detecting device 10 may output a pneumoconfirmation confirmation sound.

On the contrary, the portable counterfeit detection apparatus 10 may be forged in the bill 500 as shown in FIG. 6 or in an area other than the counterfeit element area 510 of the bill 500 as shown in FIG. In the case of approaching the light source, visible light is not detected by the light receiving unit 260 (or a small size less than the set value), and thus the speaker 140 of the portable gasoline detection device 10 does not output a pneumatic confirmation sound. You may not.

On the other hand, in the above cases, the output of the light receiving unit 260 may be as shown in FIG.

That is, FIG. 8A illustrates a value in which the output of the light receiver 260 is sequentially stored at a position (or a counterfeit banknote) in which the anti-stoke material is not formed in the bill 50. The output may continue to hold smaller values below a set value (eg, 100).

Meanwhile, FIG. 8B illustrates a value of sequentially storing the output of the light receiver 260 at the position where the anti-stoke material is formed in the bill 50, and the output of the light receiver 260 is set for a predetermined time. (Eg, 100) or more.

Hereinafter, with reference to FIGS. 9 to 18, embodiments of a method of detecting the anti-stokes material formed on the bill by the portable counterfeit detection device 10 according to the present invention will be described in detail.

As described above, the anti-stoke material formed on the banknote may absorb infrared light emitted from the light emitting unit 250 and may emit light having a higher energy (or lower wavelength) than the absorbed infrared light.

However, since the infrared light is absorbed by the anti-stoke material, the time for which the energy (or lower wavelength) of light is emitted is very short (for example, 10 ^-8 seconds), and thus emitted from the anti-stoke material. There is a difficulty in detecting the light.

According to one embodiment of the present invention, the counterfeit judging unit 270 of the portable counterfeit detection device 10 is the presence or absence of anti-Stokes material formed on the bill using the integral value of the light detection signal output from the light receiving unit 260 By judging, it is possible to more easily and accurately recognize whether the bill is forged.

FIG. 9 is a block diagram illustrating a configuration for detecting an anti-stokes material and an embodiment of the configuration of the counterfeit determination unit 270 illustrated in FIG. 2.

Referring to FIG. 9, the counterfeit determination unit 270 may include a first amplifier 1010, an integrator 1020, a second amplifier 1030, and a recognition unit 1040.

The first amplifier 1010 amplifies the photodetection signal output from the light receiving unit 260, and the integrator 1020 integrates the photodetection signal amplified by the first amplifier 1010 with respect to time to correspond to the integral value. Can output a signal.

The second amplifier 1020 may amplify the signal output from the integrator 1020 to a size recognizable by the recognition unit 1040 and then output the signal to the recognition unit 1040.

FIG. 10 is a graph illustrating an example of a method for detecting the presence or absence of an anti-stalk material by using an output signal of the light receiver, and illustrates a signal input from the second amplifier 1020 to the recognition unit 1040. An example is shown.

(A) of FIG. 10 shows the signal waveform when the anti-stoke phenomenon does not occur (for example, when an anti-stoke material is not formed in a banknote), and FIG. 10 (b) shows the anti-stalk. The signal waveform is shown when a phenomenon occurs (for example, when anti-stoke material is formed in a banknote).

Referring to FIG. 10A, when the LED included in the light emitting unit 250 is turned on for a predetermined time t1 and then turned off, the transition phenomenon caused by the anti-stoke material does not occur, and thus the LED is turned off. After that, a specific waveform signal having a voltage higher than a reference value may not be detected.

On the other hand, referring to Figure 10 (b), a transition phenomenon caused by the anti-stock material formed on the bill occurs, the specific waveform signal (A) having a voltage higher than the reference value for a predetermined time after the LED is turned off can be detected. have.

On the other hand, the waveform signal after the LED is turned off as shown in Figure 10 (b) is a value time-integrated by the integrator 1020, it is easily detected for a longer time than the light detected by the actual light receiving unit 260. Can be.

For the above operation, the light emitting unit 250 may have a circuit configuration as shown in FIG. 11 to periodically turn on and off the LED emitting infrared light.

On the other hand, the light receiving unit 260 has a circuit configuration as shown in Figure 12, it can detect the light emitted from the bill and output a signal having a voltage (or current) corresponding to its magnitude.

FIG. 13 is a circuit diagram showing an embodiment of the configuration of the first amplifier shown in FIG. 9, and FIG. 14 is a circuit diagram showing an embodiment of the configuration of the integrator shown in FIG.

13 and 14, when the voltage of the light detection signal output from the light receiving unit 260 is increased by using the diode (for example, in the optical sensor provided in the light receiving unit 260). Energy is measured), and the integrator 1020 may output an integrated value of the signal amplified by the first amplifier 1010 when the voltage of the light detection signal rises. .

Meanwhile, the above operation of the integrator 1020 may be controlled by a circuit having a configuration as shown in FIG. 16.

FIG. 15 is a circuit diagram illustrating an embodiment of the configuration of the second amplifier illustrated in FIG. 9.

The signal amplified by the second amplifying unit 1030 is input to the recognition unit 1040, the recognition unit 1040 determines the presence or absence of the anti-stalk material formed on the bill by the method described with reference to FIG. can do.

According to another embodiment of the present invention, the counterfeit judging unit 270 counts the number of consecutive times when the amount of light detected by the light receiving unit 260 is greater than or equal to the reference value after the LED of the light emitting unit 250 is turned off. When the counted number is greater than or equal to a predetermined reference number, it may be determined that anti-stoke material is formed in the bill.

Referring to FIG. 17, the LEDs of the light emitting unit 250 are periodically turned on and off, and the state in which the infrared light is not irradiated for a predetermined time t2 after the banknote is irradiated with the infrared light for the previous time t1 is repeated. Can be.

In this case, FIG. 18A illustrates a signal waveform when an anti-stoke phenomenon does not occur (for example, when an anti-stock material is not formed on a banknote), and FIG. 18B. Shows signal waveforms when an anti-stoke phenomenon occurs (for example, when an anti-stoke substance is formed in a banknote).

Referring to FIG. 18A, in the case of a bill in which an anti-stoke material is not formed, it is detected by the light receiving unit 260 and passes through the first amplifier 1010, the integrator 1020, and the second amplifier 1030. The signal input to the recognizer 1040 may not have a voltage greater than or equal to a reference value for a predetermined time t2 after the LED is turned off.

Meanwhile, referring to FIG. 18B, in the case of a banknote formed with an anti-stoke material, it is detected by the light receiving unit 260 and passes through the first amplifier 1010, the integrator 1020, and the second amplifier 1030. In the signal input to the recognition unit 1040, a specific waveform A having a voltage higher than or equal to a reference value may be detected continuously after the LED is periodically turned off.

Accordingly, the recognizer 1040 continues whether or not a specific waveform A having a voltage equal to or greater than a reference value is detected after the LED of the light emitter 250 is turned off from the signal input from the second amplifier 1030. The number of times that the specific waveform A is continuously detected can be counted.

When the number of times to be counted reaches a preset reference number (eg, ten times), the recognition unit 1040 may determine that the anti-stoke material is formed on the bill.

As described above, when the recognition unit 1040 determines that the anti-stoke material is formed in the bill, the buzzer sounds through the speaker having the circuit configuration as shown in FIG. Can be.

In FIG. 18A, the signal having the same waveform A is detected after the LED of the light emitting unit 250 is turned off from the signal input to the recognition unit 1040, but this is for convenience of description. The signal detected after the LED is turned off may be a predetermined waveform or more, and may have different waveforms in some cases.

On the other hand, when the portable counterfeit detection device 10 uses a battery as an operating power source, the output voltage decreases as the remaining battery capacity decreases, and thus the magnitude of the incident light amount irradiated from the LED of the light emitting unit 250 to the banknote. Can be reduced.

In addition, as the amount of incident light from the light emitter 250 decreases as described above, the amount of light detected by the light receiver 260 may also decrease, resulting in inaccurate determination of the signal of the counterfeit determination unit 270.

In the portable counterfeit detection apparatus 10 according to another embodiment of the present invention, the output voltage of the current battery is used by using the voltage dividing ratio of the voltage checking circuit based on the output voltage value of the battery and the voltage value used therein. If it is lower than the reference voltage, it may indicate that it is currently unavailable.

For example, by using a voltage checking unit having a circuit configuration as shown in FIG. 20, the output voltage of the battery may be periodically checked and the output voltage of the battery may be compared with a preset reference voltage. It can be periodically checked whether it is below this reference voltage.

On the other hand, when the output voltage of the battery is less than the reference voltage, a control signal for notifying it is transmitted to the display LED circuit as shown in Figure 21, so that the battery of the portable counterfeit detection device 10 should be replaced or charged Can be known to the user.

In addition, when the counterfeit determination unit 270 determines that the anti-stoke material is formed in the bill, the buzzer sounds by the speaker having the circuit configuration as shown in FIG. 19 and at the same time, as shown in FIG. 21. The display color having the same circuit configuration may be displayed or the display color may be changed.

According to another embodiment of the present invention, the portable counterfeit detection device 10 described with reference to FIGS. 1 to 21 may be connected to another device using a wired / wireless communication method to transmit and receive a signal.

For example, the portable counterfeit detection device 10 is connected to a PC, a notebook or a point of sales terminal using a USB cable, and operates by receiving a control signal from the connected device or supplying power from the connected device. Information about the received or detected result may be transmitted to the connected device.

FIG. 22 is a block diagram illustrating a configuration of a counterfeit detection system according to an exemplary embodiment of the present invention. The illustrated system may include a payment terminal 1200 and a portable counterfeit detection device 10. On the other hand, since the configuration and operation of the portable forgery detection device 10 may be the same as described with reference to Figures 1 to 21, a detailed description thereof will be omitted.

Referring to FIG. 22, the portable counterfeit detection device 10 determines whether a bill is forged using an anti-stoke material formed in a specific area of the bill, and the payment terminal 1200 is determined by the portable counterfeit detection device 10. Information about whether the banknote is counterfeit can be received and output.

As described above, in order for the payment terminal 1200 and the portable counterfeit detection apparatus 10 to interwork with each other, the portable counterfeit detection apparatus 10 may include an interface unit (not shown) for transmitting and receiving data with the payment terminal 1200. Can be.

The payment terminal 1200 is a terminal installed in a merchant to process payment, and may be implemented as a credit authorization terminal, a point of sales terminal, a wired terminal, or a wireless terminal.
