BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view for explaining an apparatus for inspecting a sealed wrapper for damage according to an embodiment of the present invention; FIG.

Referring to FIG. 1, a sealed packaging paper damaging inspection apparatus 10 includes a display unit 11, a storage unit 12, a communication unit 13, a recognition unit 14, a determination unit 15, an information generation unit 16, and a lighting unit 17.

Sealed wrapping paper refers to wrapping paper that is covered with packaging method that is shielded from external environment after packaging such as vacuum packaging / gas filling packaging. For example, the sealed wrapping paper may be in a state where gas, liquid and solid are prevented from entering and exiting from the external environment.

The display unit 11 can display various data information. For example, the display unit 11 can display information on whether the inside of the wrapping paper is changed or not.

The display unit 11 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, and a 3D display.

The storage unit 12 may store various data information. For example, the storage unit 12 may store identification code information, internal change information, internal change presence / absence determination result information, and the like.

The communication unit 13 can transmit and receive various information. For example, the communication unit 13 can receive the internal change information or the identification code information transmitted from the sensor 21 and the identification device 22. As another example, the communication unit 13 can transmit various information to an external terminal or a management server.

The recognition unit 14 can recognize the identification code included in the identification element 22. [ Identification codes may be assigned differently for each package. For example, the identification device 22 may be any one of a bar code, a QR code, and an RFID code, and the recognition unit 14 may be a device capable of recognizing any one of a bar code, a QR code, and an RFID code. As another example, the identification element may be an optical identification element. The optical identifying element will be described in detail in Fig.

The determination unit 15 can compare the internal change information recognized by the sensor 21 with the reference change information to determine whether the sealed state of the sealed wrapping paper is maintained or not. For example, the determination unit 15 can compare the internal change information recognized by the sensor 21 with the reference change information to determine whether there is a change in the internal environment of the sealed wrapping paper. The determination unit 15 may determine that the sealed state of the sealed wrapping paper is not maintained when it is determined that there is a change in the internal environment. That is, the determination unit 15 can determine that the sealed portion of the sealed wrapping paper has been damaged.

The judging unit 15 can recognize the environmental change inside the wrapping paper including the physical / chemical / biological change. The internal environmental change information may include physical change information, chemical change information, biological change information, and the like. Physical changes mean changes in temperature, volume, morphology, etc. Chemical changes mean quantitative changes in constituents such as substance, gas, and moisture. Biological changes include changes in microbial, virus, . ≪ / RTI > The degree of the change may be determined according to the degree of difference between the internal change information recognized by the sensor 21 and the reference change information. The reference change information may be a reference value for determining internal change information set for each identification code / distribution step.

The determination unit 15 can determine whether the sealed state is maintained by comparing the internal change information generated in the current distribution stage with the internal change information generated in the immediately preceding distribution stage. For example, when the humidity at the immediately preceding distribution stage is the A value, the determination unit 15 determines that there is no internal change if the humidity generated at the current distribution stage is the A value. On the other hand, if the humidity generated in the current distribution stage is a B value, the determination unit 15 determines that there is an internal change and determines that the sealed packaging portion is damaged. In other words, the judging unit 15 compares the internal change information in the current sealing state with the internal change information in the normal sealing state to determine whether the sealed packaging portion is damaged (whether or not the sealed state is maintained) It can be judged. The present invention utilizes a phenomenon in which, when the sealed packaging portion is damaged, the internal environment of the sealed packaging paper is different from that when the packaging paper is initially sealed.

The information generating unit 16 may generate information on changes in the wrapping paper according to the identification code / distribution step, external environment information upon measurement, information on the measurement date and time, and information on the measured person.

The information generating unit 16 transmits the generated information and the warning message to an external device such as a terminal or a management server used by a user who manages the package destruction of the distribution through the communication unit 13 or the generated information is stored in the storage unit 12 ). ≪ / RTI > This allows the administrator to check in real time whether the distribution packaging is damaged or not.

Here, the various pieces of information include information on internal change according to the identification code / distribution step, information on the result of determination as to whether the sealed state of the sealed wrapping paper is maintained, external environment information on the measurement, information on the measurement date and time, Information, and the like.

Thus, the writing unit 14 can recognize various information measured in the immediately preceding step included in the identification element 22 by writing various information in the identification element 22 by the writing unit 17. [ Accordingly, the recognition unit 14 can directly recognize various information measured in the immediately preceding step from the identification element 22 without receiving it from a server (not shown) or the like.

The sensor 21 may be attached to the sealed wrapping paper 20 or integrally provided in the sealed wrapping paper 20 or may be provided inside the sealed wrapping paper 20.

For example, when a wave is incident from the outside, the sensor 21 can be generated by changing the incident wave according to changes in the inside. Accordingly, the sensor 21 can recognize the internal change information. Here, waves may include electromagnetic waves, ultrasonic waves, and the like.

As another example, the sensor 21 may transmit internal change information to the determination unit 15 through a communication unit (not shown) periodically or whenever a request signal is input. For example, the sensor 21 may be a passive type having no separate power supply source or a separate power supply source, and may be an active type capable of actively transmitting internal change information to the determination unit 15 It is possible.

2 is a view for explaining a packaging damage inspection apparatus according to another embodiment of the present invention.

The display unit 101 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, and a 3D display.

The electromagnetic wave generating section 102 can radiate electromagnetic waves to the packaging paper 111 and the optical identifying element 112. [ For example, the electromagnetic wave generating unit 102 may be a device of various types capable of generating a terahertz wave. Terahertz blue An electromagnetic wave located in the region between infrared rays and microwaves, and can generally have a frequency of 0.1 THz to 10 THz. However, it should be understood that the present invention can be considered as a terahertz wave even if it is somewhat deviated from such a range, as long as those skilled in the art can easily contemplate the present invention. The wrapping paper 111 can be generated by changing the electromagnetic wave incident from the external electromagnetic wave generating portion according to changes in the inside. The optical identification element 112 can generate a natural resonance frequency when an electromagnetic wave is incident. A detailed description of the wrapping paper 111 and the optical identifying element 112 will be described later.

The detection unit 103 can detect the characteristic of the terahertz wave generated from the wrapping paper 111 and detect the intrinsic resonance frequency of the electromagnetic wave generated from the optical identification element 112. [

The detection unit 103 can detect the characteristics of the terahertz wave reflected, transmitted, diffracted, or scattered from the wrapping paper 111. Specifically, for example, the detecting unit 103 can detect the intensity of the terahertz wave or the resonant frequency of the terahertz wave generated from the wrapping paper 111 for the terahertz.

The detection unit 103 can detect the intrinsic resonance frequency of the electromagnetic wave generated from the optical identification element 112. [

The recognition unit 104 can recognize the identification code of the wrapping paper 111 based on the natural resonance frequency detected by the detection unit 103. [ The identification code may include code information capable of distinguishing a plurality of wrapping paper.

The determination unit 105 can compare the electromagnetic wave generated from the wrapping paper 111 detected by the detection unit 103 and the reference electromagnetic wave corresponding to the identification code to determine whether or not to maintain the sealed state of the sealed wrapping paper. For example, the determination unit 105 can recognize changes in the wrapping paper including physical / chemical / biological changes. Physical changes mean changes in temperature, volume, morphology, etc. Chemical changes mean quantitative changes in constituents such as substance, gas, and moisture. Biological changes include changes in microbial, virus, . ≪ / RTI > The degree of the change can be determined according to the degree of difference between the resonance frequency of the electromagnetic wave detected from the wrapping paper 111 and the resonance frequency of the reference THz wave.

The reference electromagnetic wave can have different values for each identification code / distribution step.

For example, when the difference between the resonance frequency of the electromagnetic wave detected by the detection unit 103 and the resonance frequency of the reference electromagnetic wave corresponding to the recognized identification code is larger than the set difference, It can be judged that there is an internal change.

division Processing step
Reference resonance frequency Shipping stage
Reference resonance frequency Purchase step
Reference resonance frequency Identification code 1 A B C Identification code 2 D E F Identification code 3 G H I Identification code 4 J K L

Referring to Table 1, the reference resonance frequency of the identification code 1 may be A / B / C. The reference resonance frequency may be preset or may be the resonance frequency value of the electromagnetic wave measured in the immediately preceding step. For example, when the resonance frequency of the electromagnetic wave actually detected from the wrapping paper 111 in the processing step is B, the reference resonance frequency of the delivery step may be set to B. When the resonance frequency of the electromagnetic wave actually detected from the wrapping paper 111 at the delivery step is C, the reference resonance frequency of the purchase step may be set to C. [ At this time, the judging unit 105 judges whether or not there is a change in the inside of the wrapping paper 111 based on the BA (difference value) in the processing step, and judges whether there is a change in the inside of the wrapping paper 111 It is determined whether or not there is a change, and it is possible to determine whether the sealed packaging paper 111 is kept in the sealed state based on DC (difference value) in the purchase step.

For example, the determining unit 105 may determine the resonance frequency of the electromagnetic wave based on the resonance frequency of the electromagnetic wave detected by the detecting unit 103 and the resonance frequency of the reference THz wave corresponding to the recognized ID code, 111 in the sealed state can be determined. Specifically, for example, the determination unit 105 may quantify the degree of the physical / chemical / biological change inside the wrapping paper 111 based on the difference value. For example, the determination unit 105 can derive the humidity difference based on the difference value.

In another example, the determination unit 105 compares the intensity of the terahertz wave detected by the detection unit 103 with the intensity of the reference terahertz wave corresponding to the recognized identification code at a specific wavelength, When the difference between the intensity of the terahertz wave detected by the detecting unit 103 and the intensity of the reference terahertz wave corresponding to the recognized identification code is larger than the set difference, it is determined that the sealed state of the sealed wrapping paper 111 is damaged .

The information generation unit 106 may generate information on changes in the wrapping paper according to the identification code / distribution step, external environment information upon measurement, information on the measurement date and time, and information on the measured person.

The information generating unit 106 may transmit the generated information and the warning message to an external device such as a terminal or a management server used by a user who manages the package destruction by the communication unit. This allows the administrator to check in real time whether the distribution packaging is damaged or not.

The sensing window 704 composed of the electromagnetic wave-permeable layer 702, the electric field reinforcing structure 703, the selective sensing layer 704 and the filter layer 705 is provided only in a specific portion of the entire packaging paper so that the inside of the wrapping paper can be easily detected by the non- sensing window.

[ Here, the second resonance frequency f2 is a resonance frequency of the electromagnetic wave that changes as the specific substance included in the selective sensing layer 823 is coupled to the sensing material. In other words, when a specific material is coupled to the selective sensing layer 823, the second resonant frequency f2 changes.

The determination unit (not shown) may determine the first resonance frequency f1 of the electromagnetic wave detected in the first region 810 (the resonance frequency of the reference THz wave) When the difference between the resonance frequencies is larger than the set range, it can be judged that a physical / chemical / biological change has occurred inside the packaging container (not shown).

9 is a view for explaining a sensor provided in a wrapping paper according to an embodiment of the present invention.

Referring to FIG. 9, a packaging container 900 including an area through which electromagnetic waves are transmitted may be a container for storing beverage. The packaging container 900 may include a region 910 through which electromagnetic waves are transmitted to a part of the side surface.

The sensor 920 may be provided inside the packaging container 900.

The sensor 920 includes a substrate layer 921, an electric field enhancing structure 922, an optional sensing layer 923, a filter layer 924, an electromagnetic wave transmission layer 925, a waveguide grating 926 and a substrate layer 927 .

The selective sensing layer 923 may be a layer that fixes the sensing material to the support, which bonds only with the specific material. For example, when a specific substance is a specific ion, a specific gas, moisture, a harmful substance, etc., the selective sensing layer 923 may be bonded only with a specific ion, specific gas, moisture, .

The filter layer 924 can pass only a specific material to the selective sensing layer 923. For example, the filter layer 924 may be formed on the innermost side of the packaging container 900 and may be formed of a specific material (for example, a specific ion, Specific gases, moisture, and harmful substances) may pass through the selective sensing layer 923.

If it is desired to detect a change in moisture inside the packaging container 900, the selective sensing layer 923 uses a layer capable of binding only with moisture, and the filter layer 924 uses a layer capable of passing only water Can be used.

10A to 10C are views for explaining an electric field enhanced structure according to an embodiment of the present invention.

Referring to FIG. 10A, the electric field enhancing structure may be a waveguide grating that causes Guided Mode Resonance (GMR) for a specific wavelength.

장 대역에서 매우 날카로운 공명 곡선이 그려진다. The waveguide diffraction grating layer 1002 can diffract the incident light under a given condition (wavelength of incident light, incident angle, waveguide thickness, effective refractive index, and the like). The higher order diffraction waves except for the zeroth order can form a guided mode in the waveguide diffraction grating layer 1002. At this time, the zero-order reflected wave-transmission wave occurs in guided mode and phase matching, and resonance occurs in which the energy of the waveguide mode is transmitted again to the zero-order reflected wave-transmission wave. As resonance occurs, the 0th-order reflection diffraction wave is 100% reflected by the constructive interference, and 0th-order transmission diffraction wave is 0% transmission due to destructive interference,

Very sharp resonance curves are drawn in the long bands.

FIG. 10B is a graph showing the results of a diffraction grating (n _H = 1.80, n _L = 1.72, thickness = 80 μm, period = 200 μm) formed by a SU-8 photoresist on a transparent polymethylpentene substrate (n = 1.46) GMR calculation result (resonance occurs at 0.89 THz).

10A, assuming that the dielectric constant of the cover layer 901 is? ₁ , the dielectric constant of the waveguide diffraction grating layer 1002 is? ₂ , and the dielectric constant of the lower substrate layer 1003 is? ₃ , The dielectric constant? ₂ of the diffraction grating layer can be expressed by the following equation (1).

Where ε _g is the mean value of the configuration of the diffraction grating, and repeating two types of dielectric constant (ε _H, ε _L) is, △ ε is the maximum amount of change in dielectric constant at, K is 2π / Λ, as the grid frequency Λ is the period of the grating And x is the distance from the origin to the X axis direction.

In this case, in order for the waveguide diffraction grating to resonate at a specific wavelength and incident angle of the incident light, that is, to generate the waveguide mode, the effective refractive index N of the waveguide satisfies the following condition.

)|N|<

max (

) | N | <

When a GMR occurs in a waveguide diffraction grating, the electric field is concentrated near the diffraction grating. Due to the near field enhancement phenomenon, the change in the refraction index near the waveguide diffraction grating appears as a change in the resonance frequency as a whole. Using this principle, the sensing film is formed near the waveguide grating, and the chemical-physical bonding of the fine sensing material within the sensing film is represented by a change in the resonance frequency, so that the sensing principle can be utilized as a high sensitivity sensing principle.

Here, this principle is applied to the electromagnetic wave field to form a GMR sensing element that reacts in the electromagnetic wave region in the wrapping paper, thereby making it possible to produce an electromagnetic wave sensing element with high sensitivity. In particular, the non-destructive characteristic of the electromagnetic wave can be combined with the high-sensitivity non-destructive detection.

10C is a perspective view for explaining the structure and the shape of the waveguide diffraction grating.

The diffraction grating may include grooves or ridges formed on the surface of the dielectric slab. As another example, the diffraction grating is a planar dielectric sheet having a periodically alternating refractive index (e.g., a phase grating) in the dielectric sheet. The exemplary phase grating may be formed by forming an array of periodic holes in and through the dielectric sheet.

As another example, the diffraction grating can include either a one-dimensional (1D) diffraction grating or a two-dimensional diffraction grating. The 1D diffraction grating may for example include a set of substantially straight grooves that are periodic and parallel only in a first direction (e.g. along the x-axis). An example of a 2D diffraction grating can include an array of holes in a dielectric slab or sheet, wherein the holes are periodically spaced (e.g. along both the x- and y-axes) according to two orthogonal directions . At this time, the 2D diffraction grating is also called a photonic crystal.

11 is a view for explaining an optical identifying element related to an embodiment of the present invention.

Referring to Fig. 11, the optical identification element 1100 may include m identification units. Each identification unit may include an electromagnetic wave-transparent layer 1110, a waveguide grating 1120, and a substrate layer 1130. In the present embodiment, the case where the number of identification units is eight will be described, but the number of identification units is not limited thereto. The area of the identification unit can be influenced by the irradiated area, intrinsic resonance frequency, lattice period, etc., which is most affected by the irradiated area. For example, if the diameter of the irradiation beam of the electromagnetic wave is 6 mm, the area of the identification unit may be 8 mm * 8 mm. As described above, since the diameter of the irradiation beam of the electromagnetic wave is small, the area of the identification unit is also very small. The optical identifying element 112 of FIG. 1 may be implemented with the optical identifying element 1100 of this embodiment.

The electromagnetic wave transmitting layer 1110 is made of a material that transmits electromagnetic waves.

When the electromagnetic wave transmitted through the electromagnetic wave transmission layer 1110 is irradiated, the waveguide diffraction grating 1120 can generate an electromagnetic wave having a specific resonance frequency. Here, the natural resonance frequency may be any one of the first natural resonance frequency to the n-th natural frequency. For example, the first natural resonance frequency may be f ₁ . If n is 10, the natural resonance frequency may be any one of 10 natural resonance frequencies.

The waveguide diffraction grating 1120 may be formed of a material such as photosensitive, thermal, or electrosensitive.

The waveguide grating 1120 may include grooves or ridges formed on the surface of the dielectric slab. As another example, the diffraction grating is a planar dielectric sheet having a periodically alternating refractive index (e.g., a phase grating) in the dielectric sheet. The exemplary phase grating may be formed by forming an array of periodic holes in and through the dielectric sheet.

The waveguide grating 1120 may comprise either a one-dimensional (1D) diffraction grating or a two-dimensional diffraction grating. The 1D diffraction grating may for example include a set of substantially straight grooves that are periodic and parallel only in a first direction (e.g. along the x-axis). An example of a 2D diffraction grating can include an array of holes in a dielectric slab or sheet, wherein the holes are periodically spaced (e.g. along both the x- and y-axes) according to two orthogonal directions . At this time, the 2D diffraction grating is also called a photonic crystal.

The substrate layer 1130 may be a layer capable of fixing the waveguide grating 1120 in combination with the waveguide grating 1120.

If the optical identifying element 1100 has n types of natural resonance frequencies and the number of identifying units is m, the number of identifiable identifying codes is n ^m . For example, when the number of types of the natural resonance frequencies is 10 and the number of identification units is 2, the identification code is 10 ² = 100. As such, the optical identifying element 1100 can represent 100 identification codes even if only two identification units are used. As another example, if the kind of the natural resonance frequency is 10, and the number of identification units is 8, the identification code becomes 10 ⁸ = 100.000000.

Thus, the optical identification element can represent a large amount of identification code within a small area.

In addition, since the optical identification device can not be recognized with the naked eye, the optical identification device is also excellent in security.

12A to 12D are views for specifically explaining an optical identifying element related to an embodiment of the present invention.

FIG. 12B is a graph showing electromagnetic waves transmitted from the optical identifying element. FIG.

Referring to FIG. 12B, each of the identification units 1 to n may have a specific resonance frequency f ₁ , f _{2, f 3} to fn, respectively. For example, the first identification unit 1 has a first natural resonance frequency f ₁ , the second identification unit 2 has a second natural resonance frequency f ₂ , and the n-th identification unit n May have an n-th unique resonance frequency fn.

12C is a view for explaining an optical identification element made up of 16 identification units.

12C, a total of 16 identification units are provided, and a total of 16 identification units are composed of a combination of 10 identification units 1 to 10 having respective natural resonance frequencies f ₁ , f _{2, f 3} to f ₁₀ &Lt; / RTI &gt; Specifically, the first identifying unit is a first identifying unit 1 having a first specific resonance frequency f ₁ , the second identifying unit is a fourth identifying unit 4 having a fourth specific resonance frequency f ₄ , , The third identification unit is the second identification unit 2 having the second specific resonance frequency f ₂ , and the identification units existing at the remaining positions can be composed of the identification units as shown in FIG. 2C.

12D is a diagram for explaining the number of identification codes that can be represented when the number of types of natural resonance frequencies is n and the number of identification units is m.

Referring to FIG. 12D, since there are n kinds of natural frequencies of resonance frequencies of the identification units that can be formed in each identification unit, and the optical identification devices are composed of a total of 16 identification units, n ¹⁶ do.

12E is a diagram for explaining the arrangement of various types of identification units.

Referring to FIG. 12E, the identification units may be arranged in various forms, and the type of arrangement may mean identification codes and other identification information. The identification units may be arranged in various forms, such as linear, circular, square, lattice, and crossed.

Referring to Figures 12 (a) to 12 (c), the identification units may be arranged in the form of a line, an intersection and a circle. In this case, the line shape means A object, the crossed shape means B object, and the circular band shape can mean C object. In this way, the arrangement type of the identification units can be used as the identification information.

13A to 13C are views for explaining a lighting apparatus for an identification unit according to an embodiment of the present invention.

Referring to FIG. 13A, the intrinsic resonance frequency can be set for each frequency band (G1, G2, ..., Gm). The frequency band can be set based on the frequency band that can be changed by the modulation unit (1310b in Fig. 13B). For example, when the frequency band of the modulation section (1310b of FIG. 13b) can be changed relative to the f ₂ f ₃ f in _1, a first frequency band (G1) is in the _f3 f _1. If the modulator (FIG. 13b of 1310b) the frequency band that can be changed based on the f ₅ f ₆ f at _4, a first frequency band (G1) is in the f ₆ f _4.

Referring to FIG. 13B, the lighting apparatus for the identification unit may include an identification unit 1300b and a modulation unit 1310b. Discrimination unit (1300b) is a waveguide diffraction grating having a specific resonance frequency (f ₂₎ corresponding to the frequency band (G1) is set for the terahertz wave transmitting layer made of a material that transmits the terahertz wave, the transmitted terahertz wave . &Lt; / RTI &gt;

The modulator 1310b can change the intrinsic resonance frequency of the waveguide diffraction grating to another intrinsic resonance frequency within a set frequency band. For example, the modulation section (1310b) can be changed within a frequency band (G1) set the natural resonant frequency of the waveguide diffraction grating (f ₂₎ to a different natural resonant frequency (f ₁ or f _3).

As a specific example of the method of changing the resonance frequency, the modulation section 1310b can change the intrinsic resonance frequency of the waveguide diffraction grating to another intrinsic resonance frequency within the set frequency band.

13C, the lighting apparatus for the identification unit may include an identification unit 1300c and a modulation unit 1310c. Discrimination unit (1300c) is a waveguide diffraction grating having a specific resonance frequency (f ₅₎ corresponding to the terahertz wave transmitted through layer, and the band (G2) is set for the transmitted terahertz wave made of a material that transmits the terahertz wave . &Lt; / RTI &gt;

The modulator 1310c can change the intrinsic resonance frequency of the waveguide diffraction grating to another intrinsic resonance frequency within a set frequency band. Modulator (1310c) may be changed within a frequency band (G2) is set a specific resonance frequency of the waveguide diffraction grating (f ₅₎ to a different natural resonant frequency (f ₄ or f _6).

Thus, by using the lighting apparatus for the identification unit, the user or the like can freely change the resonance frequency of the identification unit within the set resonance frequency range. Therefore, the production cost of the identification unit and the optical identification device can be reduced because the identification unit is not required to be produced for each resonance frequency. In addition, user convenience can be increased by changing the identification unit to a desired resonance frequency in the field using a lighting device for the identification unit.
