Description

Technical Field

[0001] The present invention relates to the technical field of anti-counterfeiting detection, and particularly relates to a packaging anti-counterfeiting and anti-recycling detection system and method based on RFID technology. Background Art

[0002] In the packaging industry, especially for the packaging of high-value goods such as precious cigarettes and wines, luxury goods, and medicines, there are often situations where counterfeiters counterfeit the packaging or recycle the genuine packaging for reuse. Therefore, the anti-counterfeiting and anti-recycling functions of commodity packaging are particularly important.

[0003] The existing anti-counterfeiting and anti-recycling means in the packaging industry generally determine whether the packaging has been opened or replaced based on observing whether a specific structure is damaged. Common solutions include sealing labels, tear rings, etc. Or digital technologies are used for anti-counterfeiting, and common solutions include two-dimensional codes, RFID tags, etc. The existing common anti-counterfeiting and anti-recycling means can prevent some counterfeiting, but counterfeiters recycle a large number of genuine packages, and even recycle packages that are opened or unsealed by abnormal means at high prices (for example, forcibly removing the caps of liquor products so that the sealing labels and tear rings are not damaged). Then, by separately damaging a part of the relevant structural components on the packaging to ensure that the other structural components are intact, and then assembling the intact structural components back into the overall packaging. This results in each part of the packaging of counterfeit goods coming from genuine packages, and it is very difficult to prevent counterfeiting even with digital technologies such as RFID tags, because the RFID tags used in the packages assembled by counterfeiters are also genuine. Ordinary consumers cannot detect it, and even professional anti-counterfeiting personnel are difficult to distinguish the true from the false. The fundamental reason is that the structural components of the packaging are independent of each other, and it is impossible to detect whether the product has moved, been missing, or replaced.

[0004] Therefore, the existing technology needs to be improved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that it is difficult to distinguish the true from the false in the recycling packaging counterfeiting in the prior art. The purpose is to provide a packaging anti-counterfeiting and anti-recycling detection system and method based on RFID technology, which adopts corresponding technical solutions and has the function of detecting whether the product has moved, been missing, or replaced. Even recycled packages can be detected, and it has a good anti-counterfeiting and anti-recycling effect.

[0006] The present invention is achieved by the following technical solutions:

[0007] In a first aspect, the present invention provides a packaging anti-counterfeiting and anti-recycling detection system based on RFID technology, including a main tag. The main tag is provided with a chip, and the main tag is arranged on the packaging / product. The main tag is provided with a radio frequency pad and a detection pad. The chip is used to detect the capacitance value between the radio frequency pad and the detection pad. The detection pad is connected with a capacitance induction antenna, and the capacitance induction antenna forms a capacitance induction area;

[0008] It further includes a secondary label, which is disposed on the product / package, and the secondary label non - contact coincides with the capacitance sensing area.

[0009] It further includes a reader / writer, which has RFID reading and writing functions, reads the ID information of the main label, and the capacitance values of the main label and the secondary label.

[0010] It further includes a background system, which receives the ID information and capacitance values transmitted by the reader / writer and makes an anti - counterfeiting detection judgment.

[0011] Furthermore, in the present invention, after the above - mentioned secondary label rotates or translates, the overlapping area with the capacitance sensing area changes in the overlapping direction.

[0012] Furthermore, in the present invention, the above - mentioned radio - frequency pad is connected with a radio - frequency induction antenna. A PET film is arranged on the side of the radio - frequency induction antenna close to the secondary label, and an RFID chip is arranged on the other side of the radio - frequency induction antenna.

[0013] Furthermore, in the present invention, the above - mentioned main label is installed on a sticker, and the secondary label is installed on a sticker.

[0014] Furthermore, in the present invention, an insulating part is arranged on the side of the above - mentioned main label close to the secondary label, and the insulating part is connected with the secondary label.

[0015] Furthermore, in the present invention, the above - mentioned package is provided with a mounting hole. The secondary label is connected with a prism. A retaining sleeve for preventing the prism from rotating is arranged in the mounting hole. A retaining ring is also arranged in the mounting hole. The prism is connected with a straight rod. A spring is sleeved on the straight rod. The top end of the spring is connected with the retaining ring, and the bottom end of the spring is connected with the prism. The middle part of the straight rod is set as an elastic section. A ratchet is sleeved on the straight rod. A pawl adapted to the ratchet is arranged in the mounting hole. The package is provided with a cover for covering the top end of the mounting hole.

[0016] Furthermore, in the present invention, the above - mentioned product is provided with a circular base, and the package is provided with a circular placement groove adapted to the circular base.

[0017] Furthermore, in the present invention, the above - mentioned secondary label is configured as an irregular shape.

[0018] Furthermore, in the present invention, the above - mentioned capacitance sensing area is a fixed irregular shape.

[0019] In the second aspect, the present invention also provides a method for detecting anti - counterfeiting and anti - recycling of packages, which includes a system for detecting anti - counterfeiting and anti - recycling of packages based on RFID technology, and further includes the following methods.

[0020] During production, the main label is installed on the packaging / product, and the secondary label is installed on the product / packaging. Then the product is placed inside the packaging. The main label is read once using a reader-writer, and the ID information and initial capacitance value of the main label are transmitted to the back-end system. The back-end system records and binds the ID information and initial capacitance value. During subsequent inspections, the main label is read again using the reader-writer. The back-end system is responsible for retrieving the ID information and the corresponding initial capacitance value, and determining whether there is a difference between the capacitance value during inspection and the initial capacitance value. If there is no difference, it indicates that the product has not been displaced, missing, or replaced. At the same time, the back-end system returns normal information to the reader-writer according to the determination result. If there is a difference, it indicates that the product has been displaced, missing, or replaced. At the same time, the back-end system returns abnormal information to the reader-writer according to the determination result.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] Good anti-counterfeiting and anti-recycling effect: Since the main label and the secondary label are installed on the packaging and the product respectively, when the product is placed inside the packaging, the main label and the secondary label are close to each other. A capacitance is formed between the secondary label itself and the RF pads and detection pads of the main label, which can also affect the capacitance between the RF pads and detection pads of the main label. When leaving the factory, the ID information of the main label and the capacitance values of the main label and the secondary label are read once using a reader-writer, and then the two sets of data are sent to the back-end system for binding and storage. Even if illegal elements recycle the packaging and reload it with counterfeit products with secondary labels, it is almost impossible to have exactly the same angle as when the product left the factory. As a result, the ID information and capacitance value read again do not match the initial ID information and capacitance value stored in the back-end system, and it is easy to detect that the product has been moved, missing, or replaced, so the anti-counterfeiting and anti-recycling effect is good.

[0023] Long duration: The main label and the secondary label do not require additional power supply and can be scanned and used only relying on the reader-writer. Therefore, the anti-counterfeiting and anti-recycling detection system based on RFID technology has a long-lasting anti-counterfeiting and anti-recycling effect. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Embodiment 1, in combination with Figures 1 to 7 As shown, it is an anti-counterfeiting and anti-recycling detection system for packaging based on RFID technology in an embodiment of the present invention, and the specific structure and principle are described as follows.

[0038] In this embodiment, the anti-counterfeiting and anti-recycling detection system for packaging based on RFID technology mainly consists of a main tag 1, a secondary tag 2, a reader-writer, and a background system. Among them, the main tag 1 and the secondary tag 2 cooperate to generate anti-counterfeiting ID information and capacitance information. The reader-writer is used to read the ID information of the main tag 1, as well as the capacitance information of the main tag 1 and the secondary tag 2. The background system is used to store the initial ID information and capacitance information, and judge the authenticity of the ID information and capacitance information read again by the reader-writer.

[0039] Furthermore, in combination with Figure 1 and Figure 6 As shown, the main tag 1 is installed on the bearing body. A detection pad 4 and a radio frequency pad 3 are installed on the bearing body. The secondary tag 2 is in an irregular shape. In combination with Figure 2 As shown, the radio frequency pad 3 and the detection pad 4 do not contact. The detection pad 4 is connected to a detection capacitance induction antenna 5. The capacitance induction antenna 5 and the detection pad 4 form a capacitance induction area 501, and the shape of the capacitance induction area 501 is a fixed irregular shape.

[0040] As Figure 2 shown, the capacitance value between the detection pad 4 and the left radio frequency pad 3 is C1, and the capacitance value between the detection pad 4 and the right radio frequency pad 3 is C2.

[0041] It should be noted that, in combination with Figure 1 , Figure 2 and Figure 6 As shown, the main tag 1 is provided with a radio frequency induction antenna 301 connected to a chip, and the radio frequency induction antenna 301 is used to transmit signals.

[0042] In some implementation manners of this embodiment, in combination with Figure 3 andFigure 5 As shown, the secondary tag 2 is installed on the carrying body. The secondary tag 2 is made of the same material as the RF induction antenna 301 and the capacitive induction antenna 5, such as an aluminum sheet.

[0043] Combined with Figure 2 、 Figure 3 and Figure 4 As shown, when there is only the main tag 1, the capacitance value between the detection pad 4 and the left RF pad 3 is C1, and the capacitance value between the detection pad 4 and the right RF pad 3 is C2. When the secondary tag 2 and the main tag 1 are horizontally close within 1 mm, referring to Figure 4 the change of the equivalent circuit in the middle, the secondary tag 2 can be non - contact and coincide with the RF pad 3, the detection pad 4, the capacitive induction antenna 5, and the capacitive induction area 501 in the vertical direction. The capacitance value between the secondary tag 2 and the left RF pad 3 is C3, the capacitance value between the secondary tag 2 and the detection pad 4 is C4, and the capacitance value between the secondary tag 2 and the right RF pad 3 is C5.

[0044] The secondary tag 2 can adopt Figure 7 the irregular shape shown. Since the secondary tag 2 affects the capacitance between the main tag 1 and the secondary tag 2, when the secondary tag 2 rotates or translates, the overlapping area between the secondary tag 2 and the capacitive induction area 501 changes in the overlapping direction. Therefore, the translation or rotation of the secondary tag 2 will ultimately cause the capacitance value of the main tag 1 to change, realizing the detection of whether the product 7 moves, is missing, or is replaced.

[0045] It should be noted that the carrying body on which the main tag 1 is installed and the carrying body on which the secondary tag 2 is installed can both be stickers, which can conveniently fix the main tag 1 and the secondary tag 2 on the package 6 and the product 7, and the use effect is very good. In addition, a feasible solution is to bury the secondary tag 2 inside the package 6 or the product 7. According to the different materials of the package 6 or the product 7, it can be realized by different processes. For example, for plastic parts, an injection molding process is used, and for paper - based materials, a lamination process is used, etc. This solution makes the shape, size, and vertical distance between the secondary tag 2 and the main tag 1 invisible, which can greatly increase the difficulty of imitation and the failure rate of imitation.

[0046] The reader - writer has RFID reading and writing functions, such as an existing handheld RFID reader - writer, which is used to read the ID information of the main tag 1 and the capacitance value information of the main tag 1 and the secondary tag 2.

[0047] The background system uses a cloud server, which has data storage and processing functions. The cloud server establishes a communication connection with the reader - writer through the GPRS network. The background system receives the ID information and capacitance value information transmitted by the reader - writer and can make an anti - counterfeiting detection judgment.

[0048] In some embodiments of this embodiment, combined with Figure 5As shown, an RFID chip 303 is also installed on the main label 1, and the RFID chip 303 is connected to the radio frequency induction antenna 301. A PET film 302 is provided at the top of the radio frequency induction antenna 301, and the PET film 302 covers and wraps the top of the main label 1 to form a bridge connection.

[0049] Embodiment 2: In order to achieve a better anti-counterfeiting and anti-recycling effect, the packaging anti-counterfeiting and anti-recycling detection system based on RFID technology in this embodiment is further optimized on the basis of Embodiment 1, and the specific structure and principle are described as follows.

[0050] In some embodiments of this embodiment, in combination with Figure 8 As shown, since the product 7 is usually placed inside the package 6, in this embodiment, the main label 1 is installed on the top of the product 7, and the secondary label 2 is installed on the top inside the package 6, and the secondary label 2 and the main label 1 are vertically aligned.

[0051] Furthermore, a circular base 701 is provided at the bottom of the product 7, and a circular placement groove 601 is opened at the bottom inside the package 6. The circular base 701 can be placed inside the circular placement groove 601. After the product 7 is taken out together with the circular base 701, it can be rotated at any angle and then put back into the circular placement groove 601. It is very difficult to be in exactly the same position and angle as before taking out, resulting in relative rotation between the secondary label 2 and the main label 1. The capacitance value during the reader detection is different from the initial capacitance value, and it is very easy to be detected.

[0052] Embodiment 3: In order to achieve a better use effect and anti-counterfeiting and anti-recycling effect, the packaging anti-counterfeiting and anti-recycling detection system based on RFID technology in this embodiment is further optimized on the basis of Embodiment 1, and the specific structure and principle are described as follows.

[0053] In order to achieve a better use effect, an insulating member, such as a plastic layer, is provided at the top of the main label 1, and the thickness of the plastic layer is less than 1 mm. The secondary label 2 above the main label 1 contacts the insulating member. After the product 7 is loaded into the package 6, the secondary label 2 abuts against the insulating member, which can not only ensure that the main label 1 and the secondary label 2 do not contact, but also ensure that the spacing distance is within 1 mm, with lower requirements for packing and easier operation.

[0054] In order to achieve a better anti-counterfeiting and anti-recycling effect, in combination with Figure 9 As shown, a vertically penetrating mounting hole 602 is opened at the top of the package 6. The secondary label 2 is pasted on the bottom of the plastic substrate, and a prism 201 is connected above the plastic substrate. The prism 201 can be a quadrangular prism. A bushing 603 is fixedly installed on the side wall of the mounting hole 602. The middle of the bushing 603 has a square hole, and the prism 201 just passes through this hole. Due to the limitation of the square hole, the prism 201 can only move up and down and cannot rotate.

[0055] Further, as Figure 9 shown, a straight rod 202 is installed at the top of the prism 201. The straight rod 202 is located within the mounting hole 602. The middle section of the straight rod 202 is provided as an elastic section 2021, such as rubber. A retaining ring 604 is also provided within the mounting hole 602. The straight rod 202 passes through the retaining ring 604. A spring 203 is sleeved on the straight rod 202. The top end of the spring 203 abuts against the bottom of the retaining ring 604, and the bottom end of the spring 203 abuts against the top of the prism 201. When the spring 203 is compressed, there is a tendency to push the prism 201 downward.

[0056] Furthermore, in combination with Figure 9 shown, a ratchet 204 is installed on the straight rod 202, and two pawls 605 are installed within the mounting hole 602. The pawls 605 are located on both sides of the action of the ratchet 204. The ratchet 204 is in contact with the pawls 605 to ensure that the ratchet 204 can only rotate in one direction.

[0057] During use, when packing, first place the product 7 within the package 6. The secondary label 2 is close to the main label 1 at the top of the product 7. The secondary label 2 and the main label 1 are separated by an insulating member. At this time, as Figure 9 shown, the prism 201 is located within the ferrule 603. The spring 203 pushes the secondary label 2 against the insulating member of the main label 1. Then the worker pinches the top of the straight rod 202 and rotates it by a certain angle. The prism 201 is restricted by the ferrule 603 and cannot rotate. The elastic section 2021 is twisted, and since the pawl 605 abuts against the ratchet 204, reverse rotation of the ratchet 204 is avoided, thereby preventing the elastic section 2021 from recovering. Finally, seal the top of the mounting hole 602 with a cap 606 to complete the packing work. After packing, use a reader-writer to bind the ID and the initial capacitance value with the background system. When the product 7 is taken out, the lower part of the secondary label 2 is no longer abutted and supported by the main label 1. The spring 203 pushes the prism 201 downward, causing the prism 201 to disengage from the ferrule 603. At this time, the pawl 605 and the ratchet 204 are not disengaged. Without the restriction of the ferrule 603, under the action of the restoring force of the elastic section 2021, the secondary label 2 rotates. As long as the product 7 is taken out, the secondary label 2 will surely rotate, thereby making it almost impossible to record or copy the initial position of the secondary label 2, greatly improving the anti-counterfeiting and anti-recycling effects.

[0058] Example 4. This example provides a method for detecting anti-counterfeiting and anti-recycling of a package, which is implemented using the package anti-counterfeiting and anti-recycling detection system based on RFID technology in Example 1. The specific method is as follows.

[0059] During production, install the main label 1 on the package 6 (product 7), install the secondary label 2 on the product 7 (package 6), then place the product 7 within the package 6, allow the secondary label 2 to affect the capacitance of the main label 1, and use a reader-writer to read the main label 1 once. In combination withFigure 2 , Figure 3 and Figure 4 , the main tag 1 transmits the ID information and the initial capacitance values C1 and C2 to the background system, and the background system records and binds the ID information and the initial capacitance values. During subsequent detection, the ID information and the capacitance values C1 and C2 are read again using the reader. When there is no secondary tag 2 present, the capacitance values C1 and C2 are fixed values. After the secondary tag 2 approaches, three capacitances C3, C4, and C5 are formed between the secondary tag 2 and the main tag 1, and these three capacitances are superimposed on the original C1 and C2, forming two new capacitance values. The superimposed effect is as shown in Figure 4 . The background system is responsible for retrieving the ID information and the corresponding initial capacitance value, and determining whether there is a difference between the initial capacitance value and the capacitance value detected subsequently. If there is no difference, it means that the product 7 has not been displaced, missing, or replaced. At the same time, the background system returns a normal message to the reader according to the determination result; if there is a difference, it means that the product 7 has been displaced, missing, or replaced. At the same time, the background system returns an abnormal message to the reader according to the determination result.

[0060] It should be noted that a certain redundancy is set for the capacitance value difference determination in the background system. For example, when the change amount is within 10% or 20%, it is still determined to be normal, so as to solve the problem of misjudgment caused by the slight displacement between the product 7 and the package 6 due to the product 7's mating tolerance or other external force factors.

[0061] To prevent counterfeiters from trial and error, a mechanism to prevent counterfeiters from trial and error is added to the background system. When the capacitance value corresponding to the ID information read by the reader shows a change amount exceeding 10% or 20% once in the determination of the background system, it is determined that the product 7 has been displaced, missing, or replaced, and this situation is recorded in the background system. Subsequently, even if the change amount of the capacitance value corresponding to this ID information returns to within 10% or 20% again, it is regarded as the counterfeiter's trial and error, and an abnormal message is still returned to the reader.

[0062] In summary, in the first aspect, the present invention provides a packaging anti-counterfeiting and anti-recycling detection system based on RFID technology, which includes a main tag 1 with a chip. The main tag 1 is disposed on the packaging 6 / product 7. The main tag 1 is provided with a radio frequency pad 3 and a detection pad 4. The chip is used to detect the capacitance value between the radio frequency pad 3 and the detection pad 4. The detection pad 4 is connected to a capacitance induction antenna 5, and the capacitance induction antenna 5 forms a capacitance induction area 501. It further includes a secondary tag 2 disposed on the product 7 / package 6 and non-contact coincident with the capacitance induction area 501. It also includes a reader-writer with RFID reading and writing functions to read the ID information and capacitance values of the main tag 1 and the secondary tag 2. It further includes a background system that receives the ID information and capacitance values transmitted by the reader-writer to make an anti-counterfeiting detection judgment. After the secondary tag 2 rotates or translates, the overlapping area with the capacitance induction area 501 changes in the coincident direction.

The secondary tag 2 is configured as an irregular shape.

The background system is responsible for retrieving the ID information and the corresponding initial capacitance value, and determining whether there is a difference between the capacitance value during detection and the initial capacitance value. If there is no difference, it means that the product 7 has not been displaced, missing, or replaced. At the same time, the background system returns a normal message to the reader according to the determination result. If there is a difference, it means that the product 7 has been displaced, missing, or replaced.
