Description

Technical Field

[0001] The present invention relates to the technical field of OBU anti-disassembly systems, and particularly to an OBU anti-disassembly system combined with NFC. Background Art

[0002] The Electronic Toll Collection (ETC) system has been implemented for national networking and popularized. The RFID technology also has extensive applications in various fields of the national economy and has developed relatively maturely.

[0003] As the in-vehicle unit of the ETC system, the main anti-disassembly method of the OBU is mechanical physical anti-disassembly. However, in some scenarios with high anti-disassembly requirements, although the mechanical contacts for anti-disassembly can be not damaged when the electronic tag is disassembled, the mechanical anti-disassembly function cannot be exerted.

[0004] Therefore, an OBU anti-disassembly system combined with NFC is proposed for the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an OBU anti-disassembly system combined with NFC, including an OBU body. An OBU adhesive tape is provided on the back of the OBU body. An NFC high-frequency frangible electronic tag is pasted on the OBU adhesive tape. The side of the NFC high-frequency frangible electronic tag away from the OBU adhesive tape is pasted on the glass. A touch column is arranged inside the OBU body. One end of the touch column is connected to a trigger switch. The trigger switch is arranged inside the OBU body. The other end of the touch column sequentially penetrates through the OBU body, the OBU adhesive tape, and the NFC high-frequency frangible electronic tag and abuts against the windshield. The OBU body authenticates the integrity status of the NFC high-frequency frangible electronic tag through communication between its internal NFC module and the NFC high-frequency frangible electronic tag.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0007] By arranging an NFC high-frequency frangible electronic tag between the OBU adhesive tape and the windshield, cooperating with the touch column and the trigger switch, and authenticating the integrity status of the electronic tag through communication between the internal NFC module of the OBU body and the NFC high-frequency frangible electronic tag, the present invention realizes double protection for OBU anti-transfer. Moreover, after the NFC high-frequency frangible electronic tag is pasted on the attachment, it will become invalid when disassembled and can no longer identify the tag information, thus playing an anti-counterfeiting role. Combining the original mechanical physical anti-disassembly of the OBU with the frangible and invalid anti-counterfeiting characteristics of the NFC high-frequency frangible electronic tag makes the OBU anti-disassembly more effective.

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] As shown in the attached Figure 1 figure, an OBU anti-dismantling system combined with NFC provided by the present invention includes an OBU body 5. An OBU adhesive 2 is provided on the back of the OBU body 5. An NFC high-frequency fragile electronic tag 1 is pasted on the OBU adhesive 2. One side of the NFC high-frequency fragile electronic tag 1 away from the OBU adhesive 2 is pasted on the glass 3. A trigger post 4 is provided inside the OBU body 5. One end of the trigger post 4 is connected to a trigger switch 6. The other end of the trigger post 4 sequentially passes through the OBU body 5, the OBU adhesive 2, and the NFC high-frequency fragile electronic tag 1 and abuts against the windshield 3.

[0014] Specifically, the OBU body 5 communicates with the NFC high-frequency fragile electronic tag 1 through its internal NFC module to authenticate the integrity status of the NFC high-frequency fragile electronic tag 1.

[0015] Specifically, the trigger switch 6 is provided inside the OBU body 5.

[0016] Working principle: As shown in the attached Figure 2 figure:

[0017] Step 1: Paste the OBU body 5 on the windshield through the OBU adhesive 2. Add an NFC high-frequency fragile electronic tag 1 between the windshield 3 and the OBU adhesive 2. The OBU body 5 communicates with the NFC high-frequency fragile electronic tag 1 through its internal NFC module to authenticate the integrity status of the electronic tag, and cooperate with the trigger post 4 and the supporting trigger switch 6 to provide double protection for OBU anti-dismantling. When the OBU body 5 is dismantled, the NFC high-frequency fragile electronic tag 1 will be physically damaged, or the trigger post 4 will pop up, or both will occur simultaneously;

[0018] Step 2: When judging the OBU status, since the UID information of the NFC high-frequency fragile electronic tag 1 is pre-stored inside the OBU body 5, when the UID information obtained by the OBU body 5 is inconsistent with the pre-stored UID, or when the OBU body 5 cannot communicate with the NFC high-frequency fragile electronic tag 1, or when the OBU body 5 finds that the trigger post 4 pops up, it is determined that the communication fails;

[0019] Step 3: After the OBU determines that the status is the tag failure status, stop the transaction with the RSU, and the transaction fails;

[0020] Step 3: On the contrary, if the situation in Step 2 does not occur, it is determined that the communication is successful, and the transaction with the RSU is normal.

[0021] Using the technical solution described in the present invention, or a person skilled in the art designs a similar technical solution inspired by the technical solution of the present invention and achieves the above technical effects, all of which fall within the protection scope of the present invention.
