DETAILED DESCRIPTION

[0025] The present application will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present application. These all belong to the protection scope of the present application.

[0026] Example 1 like Figure 1 As shown, the present invention provides an RFID-based anti-transfer device comprising: an RFID main control component 1, a power supply unit 2, and a trigger structure 303. The power supply unit 2 is electrically connected to the RFID main control component 1 and is used to supply power to the RFID main control component 1. Both are mounted on a second component. The trigger structure 303 is mounted on or integrally formed with the first component. (See reference...) Figure 4 As shown, the trigger structure 303 can be a protrusion structure. Through the relative movement between the first component and the second component, the trigger structure 303 comes into contact with the RFID master control component 1, thereby triggering the RFID master control component 1.

[0027] The RFID main control component 1 includes a circuit board 100 and a microcontroller 101 and a trigger unit 104 connected to the circuit board 100. The microcontroller 101 is electrically connected to the RFID tag 102 and the trigger unit 104 via the circuit board 100. Specifically, the microcontroller 101 and the RFID tag 102 can be connected via the I2C protocol, which is not a limitation of this invention. When the first component and the second component move relative to each other, the trigger structure 303 can contact the trigger unit 104 on the movement path, thereby activating the microcontroller 101 by receiving a signal from the trigger unit 104. The microcontroller then sends a corresponding signal to the RFID tag 102, at which point the RFID tag 102 knows that the item it is holding has been opened. The trigger unit 104 can be a toggle switch, a dome switch, or a pressure sensor. Contact with the trigger structure 303 generates a signal distinct from the non-contact state. The RFID tag 102 is used to establish near-field communication with the terminal device when scanned, and can also trigger the activation of the microcontroller 101 when scanned.

[0028] In addition, the RFID main control component 1 also includes an Internet of Things (NB-IoT) module 103 and a communication antenna 105. The NB-IoT module 103 is electrically connected to the microcontroller, and the communication antenna 105 is electrically connected to the NB-IoT module 103, for example, via a pin connection. The NB-IoT module 103 includes an NB-IoT wireless communication module and a SIM card (such as a patch SIM card). The SIM card is connected to the NB-IoT wireless communication module, and the NB-IoT wireless communication module is electrically connected to the microcontroller 101. When the microcontroller 101 is woken up, the NB-IoT module 103 can connect to the network through the communication antenna 105 and establish communication with the backend server, so that the backend server can also know and record the unique identification code, opening status information, and location information of the RFID-based anti-tampering device.

[0029] Through the above structure, as long as the product where the anti-transfer device based on RFID is located is opened, that is, the relative movement between the first part and the second part of the product occurs, the trigger structure 303 can trigger the activation of the microcontroller 101 in time, so that the RFID tag 102 can receive the signal sent by the microcontroller 101 in time, so as to execute the anti-fake function of itself, such as writing the opening information into the memory of itself, etc.

[0030] In the present embodiment, when the anti-transfer device is transferred, the trigger unit 104 is triggered, the trigger unit 104 sends an electrical signal for awakening to the microcontroller 101, and if the microcontroller 101 has not self-destroyed, the microcontroller 101 updates the opening state information in the RFID tag, records that the corresponding product has been opened, and then the microcontroller 101 self-destroys. The microcontroller 101 after self-destruction can no longer be awakened by the outside.

[0031] When the RFID tag 102 is scanned and read by the terminal device, the RFID tag 102 sends an electrical signal for awakening to the microcontroller 101, and if the microcontroller 101 has not self-destroyed, the microcontroller 101 sends a second identification code to the RFID tag 102, the RFID tag 102 feeds back encrypted identification information containing the second identification code and the first identification code of the RFID tag 102 itself, and if the microcontroller 101 has self-destroyed, the RFID tag 102 feeds back encrypted identification information containing the first identification code of the RFID tag 102 itself. The first identification code contains the unique identification code of the RFID tag 102 and the opening state information. The second identification code has many forms, can be the IMEI of the microcontroller itself, can be the sim card number of the communication module, or can be a certain management number defined in the memory, such as adding a characteristic character on the basis of the first identification code to inform the terminal that this is sent by the microcontroller, and the first identification code information is different. The encryption algorithm can use the national secret SM2 algorithm. At the same time of scanning by the terminal device, the terminal device establishes communication with the station tube server through the network, and can also query whether there is the opening state information of the opened opening corresponding to the unique identification code.

[0032] Embodiment 2 This invention also provides an RFID-based anti-transfer system, including the aforementioned RFID-based anti-transfer device and a judgment module. The judgment module acquires identification information; if the identification information does not contain a second identification code, it determines that the RFID tag 102 has been transferred; if the identification information contains a second identification code, it determines that the RFID tag 102 has not been transferred. In some embodiments, the judgment module can be configured on a backend server. The judgment module acquires identification information from the terminal device reading the RFID tag 102 and performs the judgment. The backend server records the opening status information in the identification information into the storage data corresponding to the unique identification code in the identification information. When the terminal device sends the identification information, it can also send its own location information. The backend server simultaneously records the location of the anti-transfer device when it is scanned, facilitating product traceability and other related work.

[0033] In other embodiments, the judgment module can also be configured on a terminal device capable of reading the RFID tag 102, and the judgment module performs the judgment on the terminal device. The terminal device sends the identification information to the backend server, and the backend server records the opening status information in the identification information into the storage data corresponding to the unique identification code in the identification information. When the terminal device sends the identification information, it can also send its own location information at the same time, and the backend server simultaneously records the location of the anti-transfer device when it is scanned, so as to facilitate product traceability and other work.

[0034] Example 3 This invention also provides an RFID-based anti-transfer method, which also employs the aforementioned RFID-based anti-transfer device. The method includes: Status monitoring steps: When the trigger unit 104 is triggered, the microcontroller 101 is activated. The microcontroller 101 updates the opening status information in the RFID tag 102, and then commands the microcontroller 101 to self-destruct. Before self-destructing, the microcontroller 101 controls the RFID tag 102 to send its unique identification code, location information, and opening status information to the backend server. The backend server records the opening status information and location information in the storage data corresponding to the unique identification code.

[0035] Tag reading steps: When the RFID tag 102 is read by the terminal device, the microcontroller 101 is activated. If the microcontroller 101 has not self-destructed, it sends a second identification code to the RFID tag 102. The RFID tag 102 responds with encrypted identification information containing the second identification code and its own first identification code. If the microcontroller 101 has self-destructed, the RFID tag 102 responds with encrypted identification information containing its own first identification code. At this time, the identification information can also be sent to the backend server via the terminal device reading the RFID tag 102. The backend server records the opening status information and the terminal device's location information into the storage data corresponding to the unique identification code in the identification information.

[0036] Judgment steps: Based on the identification information, if there is no second identification code in the identification information, it is determined that the RFID tag 102 has been transferred; if there is a second identification code in the identification information, it is determined that the RFID tag 102 has not been transferred.

[0037] Example 4 Figure 2 The illustration shows an RFID-based anti-transfer bottle cap, representing a specific application scenario of the aforementioned RFID-based anti-transfer device. It includes a bottle cap body 3 and an RFID-based anti-transfer device. The bottle cap body 3 includes an outer shell 301 and an inner shell 304, serving as the first and second components, respectively. The outer shell 301 is fitted over the inner shell 304, forming a receiving space between them. The RFID main control component 1 and the power supply unit 2 are located within this receiving space.

[0038] like Figure 3 As shown, a trigger structure 303 is connected to the side of the inner wall of the outer shell 301. The trigger structure 303 is a protrusion. Multiple reinforcing ribs 302 are connected to the top of the inner wall of the outer shell 301 to increase the structural strength of the outer shell 301.

[0039] like Figure 4 As shown, in this embodiment, the top surface of the inner housing 304 is recessed inward to form a cavity, and the circuit board 100 is located inside the cavity. The outer wall of the inner housing 304 includes an RFID tag fixing groove 307, in which the RFID tag 102 is fixed. The outer wall of the inner housing 304 also includes a communication antenna fixing groove 308, in which the communication antenna 105 is fixed. In this way, the gap between the outer housing 301 and the inner housing 304 can be effectively reduced, making the bottle cap structure more compact. The effect after the inner housing 304 is assembled is as follows: Figure 5As shown, the RFID tag fixing slot 307 and the communication antenna fixing slot 308 have no overlap in the vertical direction. The advantage of this is that it can avoid mutual interference between the antennas in the two slots.

[0040] like Figure 6 As shown, when the outer shell 301 and inner shell 304 are assembled together, the inner shell 304 is confined within the outer shell 301 by a limiting structure and is difficult to detach, while the two are movably connected. At this time, the triggering structure 303 on the outer shell 301 has not yet come into contact with the triggering unit 104. Figure 7 As shown, when it is necessary to open the bottle cap, the outer shell 301 is rotated to move the trigger structure 303 to the position of the trigger unit 104 to form contact, thereby activating the microcontroller. At this time, the outer shell 301 abuts against the inner shell 304 through the trigger structure 303, so that the inner shell 304 limits the trigger structure 303, thereby allowing the outer shell 301 to drive the inner shell 304 to rotate, causing the bottle cap to detach from the bottle.

[0041] To ensure a more secure fixation of the RFID main control component 1, multiple clips 305 are connected to the inner wall of the recess to secure the circuit board 100 and prevent it from detaching from the recess. A stop structure 306 is connected to the inner wall of the recess, and the trigger unit 104 abuts against the stop structure 306. This stop structure supports the trigger unit 104 when the trigger structure 303 contacts it. It also supports the trigger unit 104 when the outer shell 301 and inner shell 304 rotate relative to each other, preventing it from rotating and failing to make contact with the trigger structure 303. A limiting protrusion is also connected to the inner wall of the recess. A corresponding limiting recess is provided on the circuit board 100, and the limiting protrusion is located within the limiting recess to circumferentially limit the circuit board 100, preventing it from deflecting within the recess.

[0042] The RFID-based anti-transfer device of the present invention can also be applied to other types of containers, such as packaging boxes. The trigger structure 303 can be set inside the box lid, and the RFID main control component 1 and the power supply unit 2 can be set inside the box body, so that the microcontroller 101 can be triggered and activated in time when the box lid is separated from the box body.
