Description

Technical Field

[0001] The present invention relates to the field of anti-counterfeiting equipment, and in particular to a Bluetooth anti-counterfeiting label, a Bluetooth anti-counterfeiting system and an anti-counterfeiting verification method. Background Art

[0002] Anti-counterfeiting labels are the main means of anti-counterfeiting in the existing technology. Currently, anti-counterfeiting labels are generally paper adhesive anti-counterfeiting labels. Users verify by scanning the QR code or barcode on the label. Especially for valuables such as porcelain, this conventional label has a low anti-counterfeiting coefficient and is easy to be torn when attached to the surface. It is also easy to be damaged and even replaced maliciously, resulting in fake products being affixed with real anti-counterfeiting labels. Some products are difficult to stick on the surface or hang on it. In actual use, the anti-counterfeiting effect of the anti-counterfeiting label is very low. Summary of the Invention

[0003] In order to solve the problem that existing anti-counterfeiting labels are easily destroyed or replaced, the present invention provides a Bluetooth anti-counterfeiting label that can prevent disassembly and a Bluetooth anti-counterfeiting system used by the corresponding Bluetooth anti-counterfeiting label. In order to achieve the above purpose, the present invention provides a Bluetooth anti-counterfeiting label, including a shell, a circuit board and a battery are arranged in the shell, the battery is electrically connected to the circuit board, the circuit board includes a control unit, the control unit is connected to a Bluetooth module, and also includes a telescopic mechanism, one end of the telescopic mechanism contacts the circuit board and the other end passes through the shell; the telescopic mechanism includes a first spring pin and a second spring pin made of metal, one end of the first spring pin and the second spring pin is electrically connected to the control unit, and the other end is provided with a movable conductive metal sheet; when one side of the conductive metal sheet contacts the first spring pin and the second spring pin, the control unit, the first spring pin, the conductive metal sheet, and the second spring pin form a loop.

[0004] Furthermore, a spring is sleeved around the periphery of the first spring pin and the second spring pin, and the spring is sleeved in a metal tube.

[0005] In the above technical solution, a retractable head is provided on a side of the conductive metal sheet away from the first spring pin; the retractable head can squeeze the conductive metal sheet to make it contact with the first spring pin and the second spring pin.

[0006] Preferably, a soft adhesive is provided on the side of the housing close to the telescopic mechanism, and the soft adhesive is sleeved on the telescopic mechanism; a double-sided adhesive is attached to the side of the soft adhesive away from the housing. The soft adhesive is used to adhere to non-planar contact surfaces.

[0007] In the above technical solution, there is a gap between the soft glue and the shell.

[0008] Furthermore, a sleeve is provided at the gap to provide support.

[0009] As a preferred technical solution, the shell is a transparent or translucent structure.

[0010] On the basis of the above technical solution, as a preferred technical solution, a signal light is provided in the housing, and the signal light is electrically connected to the control unit.

[0011] The telescopic mechanism of the Bluetooth anti-counterfeiting tag of the present invention is in a compressed state during normal operation. Once the telescopic mechanism loosens, the first spring pin and the second spring pin pop out the conductive metal sheet, and the control unit cannot receive the signal, indicating that the Bluetooth anti-counterfeiting tag has been damaged or moved by someone. The control unit can make corresponding processing based on the signal, such as sending a signal to a remote server, or directly triggering a self-destruction action, etc., thereby ensuring that the Bluetooth anti-counterfeiting tag is not replaced or damaged by anyone.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 2As shown, in some embodiments, the present invention provides a Bluetooth anti-counterfeiting label, comprising a housing 10, within which a circuit board 20 and a battery 30 are disposed. The battery 30 is electrically connected to the circuit board 20 to power the entire circuit, resulting in a compact design and low power consumption. The circuit board 20 primarily includes a control unit and a Bluetooth module. The control unit is configured to receive signals transmitted from the Bluetooth module and then perform corresponding information processing. The control module may utilize a single-chip microcomputer, such as an STM32 series microcontroller, or other processors.

[0028] The purpose of the present invention is to prevent the Bluetooth tag from being disassembled or maliciously damaged. To achieve this purpose,

[0029] like Figure 1 As shown, the Bluetooth anti-counterfeiting label further includes a telescopic mechanism 40, one end of which contacts the circuit board 20, and the other end passes through the housing 10; specifically, as shown in FIG. Figure 2 As shown, the telescopic mechanism 40 includes a first spring pin 401 and a second spring pin 402 made of metal. One end of the first spring pin 401 and the second spring pin 402 are electrically connected to the control unit. For example, the first spring pin 401 is connected to an I / O port of the single-chip microcomputer, and the second spring pin 402 is connected to another I / O port of the single-chip microcomputer; the other end is provided with a movable conductive metal sheet 403; when one side of the conductive metal sheet 403 contacts the first spring pin 401 and the second spring pin 402, the control unit, the first spring pin 401, the conductive metal sheet 403, and the second spring pin 402 form a loop, and the control unit receives a signal. When the conductive metal sheet 403 When the tag is away from the first spring pin 401 and the second spring pin 402, the loop is disconnected and the control unit cannot receive the signal. When the Bluetooth anti-counterfeiting tag is working normally, the telescopic mechanism is in a compressed state, like a normally closed switch. Once the telescopic mechanism is loosened, the first spring pin 401 and the second spring pin 402 pop out of the conductive metal sheet 403, just like the normally closed switch is disconnected. The control unit cannot receive the signal, indicating that the Bluetooth anti-counterfeiting tag has been damaged or moved. The control unit can make corresponding processing based on the signal, such as sending a signal to a remote server, or directly triggering a self-destruction action, etc., to achieve a self-destruction effect, thereby ensuring that the Bluetooth anti-counterfeiting tag is not replaced or damaged.

[0030] It should also be noted that although in this embodiment, the first spring pin 401 and the second spring pin 402 are connected to the single-chip microcomputer, the protection scope of the present invention is not limited to this. Other connection methods are also within the protection scope of the present invention. For example, the first spring pin 401 is connected to one end of the battery, and the second spring pin 402 is connected to the power supply interface of the single-chip microcomputer. When the Bluetooth anti-counterfeiting tag is working normally, the telescopic mechanism is in a compressed state, and the battery can power the entire circuit board. Once the telescopic mechanism is loose, the first spring pin 401 and the second spring pin 402 are disconnected from the conductive metal sheet 403, the battery is directly powered off, the entire Bluetooth anti-counterfeiting tag stops working, or the backup battery is activated to send a signal to the remote server or directly trigger a self-destruction action, etc., which can also achieve the purpose of the present invention.

[0031] Specifically, the internal structure of the Bluetooth tag of this embodiment is as follows Figure 3 As shown, the sleeve 405 is tightly connected to the shell 10, and inside it are a first spring pin 401, a second spring pin 402, a telescopic head 406 and a spring 404. The lower part of the telescopic head 406 is provided with a conductive metal sheet 403, and the spring 404 is located below the telescopic head 406 and outside the first spring pin 401 and the second spring pin 402. The first spring pin 401 and the second spring pin 402 are respectively surrounded and fixed by the shell 10, and their lower ends are connected to the circuit board. The connection method can be direct contact or connection through a wire. When sticking the label, the telescopic head 406 is pressed toward the object, and the telescopic head 406 squeezes the conductive metal sheet 403, the spring 404 is compressed, and the conductive metal sheet 403 contacts the first spring pin 401 and the second spring pin 402. The circuit is connected, and the label is fixed. The anti-counterfeiting label can be fixed to the object by sticking, welding bolts, etc.

[0032] In some embodiments, the retractable head 406 is made of silicone and is hollowed out inside. This structure further reduces the weight of the Bluetooth tag and provides a certain buffer when the retractable head 406 squeezes the conductive metal sheet 403 .

[0033] In some embodiments, in order to facilitate the fixing of the Bluetooth anti-counterfeiting label on porcelain, a soft adhesive 50 is provided on the side of the shell 10 close to the telescopic mechanism 40. The soft adhesive 50 is sleeved on the telescopic mechanism 40. There is a gap between the soft adhesive 50 and the shell 10. A sleeve 70 is provided in the gap to play a supporting role. The side of the soft adhesive 50 away from the shell 10 is affixed with double-sided tape 60. The soft adhesive is used to adhere to non-planar contact surfaces. Figure 3 As shown, a portion of the telescopic head 406 is limited below the soft glue 50 by the sleeve 405, which can prevent the spring 404 from ejecting the telescopic head 406 when the label is removed.

[0034] In some embodiments, in order to prevent the Bluetooth tag from being accidentally damaged and to ensure the aesthetics of the item, the housing 10 can be set to a transparent or translucent structure; a signal light is set in the housing 10, and the signal light is electrically connected to the control unit. When the Bluetooth anti-counterfeiting tag is attached, the signal light will light up for a period of time, indicating that the attachment is successful. The length of time the light is on can be controlled by setting a program. This will not affect the appearance and appreciation value of the artwork, and the tag will not be easily touched or dropped.

[0035] In some embodiments, in order to prevent the Bluetooth tag from triggering the self-destruct program during debugging, a start button is provided on the housing 10.

[0036] The start switch 101 is connected to the control unit. The start switch 101 can be turned on after the Bluetooth anti-counterfeiting label is fixedly installed.

[0037] In some embodiments, the present invention also provides a Bluetooth anti-counterfeiting system, such as Figure 4 As shown, the Bluetooth anti-counterfeiting system includes:

[0038] The server 100 is used to calculate the verification request using the calculation factor; a cloud server or a local server can be used.

[0039] The Bluetooth anti-counterfeiting system further includes a Bluetooth anti-counterfeiting label 200, which is used to calculate the verification request. In this system, the Bluetooth anti-counterfeiting label adopts the Bluetooth anti-counterfeiting label in any of the above embodiments. In addition, the circuit structure of the Bluetooth anti-counterfeiting label is as follows: Figure 5 As shown, the Bluetooth security tag 200 includes a control unit 2001, which is used for signal exchange between various modules; a battery 2002, which is used to provide power to the Bluetooth security tag; a Bluetooth module 2003, which is used to establish a communication link between the Bluetooth security tag 200 and the terminal 300 and exchange data; and a serial port module 2004, which serves as a debugging interface and is used to download the seed of the Bluetooth security tag when it leaves the factory. In addition, the Bluetooth security tag is also equipped with a self-destruction module 2005. The self-destruction principle can be implemented in various ways, the simplest way is to directly cut off the power; in addition, the Bluetooth security tag also includes an indicator light 2006, which is used to indicate the working status of the Bluetooth security tag.

[0040] The Bluetooth anti-counterfeiting system further includes a terminal 300, which is used to send a verification request and compare the calculation result of the server with the calculation result of the Bluetooth anti-counterfeiting label. The terminal can be a mobile phone, a pad, etc.

[0041] The entire Bluetooth anti-counterfeiting verification process works as follows: When a consumer needs to verify the authenticity of an item equipped with a Bluetooth anti-counterfeiting tag, they can take out their mobile phone, open a designated app or mini-program, and then approach the corresponding item. The mobile phone will send a verification request to the Bluetooth anti-counterfeiting tag. If the tag has self-destructed, it will return self-destruction information. If the tag has not self-destructed, the Bluetooth anti-counterfeiting tag will return a first calculation result and the tag ID to the mobile phone after performing an encrypted calculation based on the seed information and the current time. The mobile phone will then send the verification request containing the first calculation result and the tag ID to the server 100. The server 100 will find the corresponding seed based on the tag ID, and obtain a second calculation result after performing the same encrypted calculation based on the seed information and the current time. The server will then compare the first and second calculation results. If they are consistent, the item is authentic; if they are inconsistent, it is a counterfeit. The verification result is then returned to the mobile phone, completing the verification process.

[0042] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
