Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing technology, and in particular to an electronic seal for semi-active security status detection. Background Technology

[0002] Electronic seals are disposable plastic-shell seals that are self-locking, tamper-evident, and feature barcodes, 2D barcodes, and NFC chips. They can be widely used in various fields, such as being installed in the mounting holes of trucks during transport to detect whether the truck has been opened during transit.

[0003] Existing electronic seals only prevent opening through physical structure and lack active detection mechanisms. Once damaged, they can be easily restored. Status detection relies on manual inspection and cannot be monitored electronically in real time. This makes it difficult to detect abnormalities during transportation or storage in a timely manner, which can easily lead to disputes. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing electronic seals being easily restored after being damaged and lacking real-time electronic monitoring, making it difficult to detect abnormalities in a timely manner during transportation or warehousing. Therefore, this invention proposes a semi-active electronic seal for security status detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An electronic seal for semi-active security status detection includes a galvanized steel wire, an electronic lock body, a riveting sleeve, an electronic lock cylinder, a hexagonal lock cylinder, an NFC control board, a battery assembly, a lock body sealing cover, a first spring contact, a second spring contact, and a plastic-coated outer shell for the lock body. The tip of the galvanized steel wire passes through the electronic lock body inlet hole and exits through the electronic lock body outlet hole, forming a one-way locking structure with the electronic lock body. The NFC control board integrates a core processing unit and an NFC chip, used to detect the seal status and exchange data via NFC communication.

[0006] Preferably, the electronic lock body and the lock body sealing cover are sealed together by a lock body sealing line, and the exterior is plastic-coated by a lock body plastic-coating hot melt line to form a waterproof and dustproof structure.

[0007] Preferably, after the hexagonal lock cylinder and the electronic lock cylinder are installed, they form a hexagonal lock cylinder limiting point. The first spring contact is electrically connected to the NFC control board through the first spring contact contact point and the first spring contact welding point. The second spring contact is electrically connected to the NFC control board through the second spring contact welding point and the second spring contact contact point, forming a continuity detection circuit.

[0008] Preferably, the NFC control board is fixed to the electronic lock body by a support rib, the electronic lock core has a battery compartment inside, the battery assembly is installed in the battery compartment, the first spring contact is fixed in the first spring contact mounting groove, and the second spring contact is fixed in the first spring contact mounting groove to ensure stable conduction with the galvanized steel wire.

[0009] Preferably, the first spring contact point is connected to the hexagonal lock core and the first spring contact point, and the second spring contact point is connected to the riveting sleeve and the second spring contact point, forming a closed detection circuit through galvanized steel wire, used to detect whether the seal has been damaged.

[0010] Preferably, the NFC control board is provided with an NFC induction coil and a battery component mounting base. The NFC induction coil is used to communicate with a mobile phone or handheld device, and the battery component mounting base is used to fix the battery component and power the core processing unit. The core processing unit monitors the conduction status of the spring contact in real time and uploads data to the management platform through the NFC chip.

[0011] Compared with the prior art, this utility model provides an electronic seal for semi-active security status detection, which has the following advantages: 1.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-6 An electronic seal for semi-active security status detection includes a galvanized steel wire 1, an electronic lock body 2, a riveting sleeve 3, an electronic lock cylinder 4, a hexagonal lock cylinder 5, an NFC control board 6, a battery assembly 7, a lock body sealing cover 8, a spring contact 19, a spring contact 210, and a plastic-coated outer shell 11 for the lock body. The tip 101 of the galvanized steel wire 1 passes through the electronic lock body inlet hole 102 and exits through the electronic lock body outlet hole 104, forming a one-way locking structure with the electronic lock body 2. As the core component for physical locking, the tip 101 of the galvanized steel wire 1 forms a through path through the inlet hole 102 and outlet hole 104 on the electronic lock body 2. The one-way locking structure achieves one-way locking after locking, ensuring that the seal cannot be pulled out in reverse after installation.

[0022] The electronic lock body 2 and the lock body sealing cover 8 are sealed together by the lock body sealing line 103. Externally, the lock body is plastic-coated using a hot-melt plastic coating line 105, forming a waterproof and dustproof structure. The electronic lock body 2 and the lock body sealing cover 8 are physically sealed by the annular lock body sealing line 103, preventing moisture and dust from entering the internal cavity. Externally, the entire lock body is plastic-coated using the hot-melt plastic coating line 105, forming a plastic-coated outer shell 11, further enhancing waterproof and dustproof performance and adapting to outdoor or humid environments. This design ensures that the internal electronic components are protected from environmental corrosion, improving equipment reliability.

[0023] After the hexagonal lock cylinder 5 and the electronic lock cylinder 4 are installed, they form a hexagonal lock cylinder limiting point 201. The first spring contact 9 is electrically connected to the NFC control board 6 through the first spring contact contact point 202 and the first spring contact welding point 203. The second spring contact 10 is electrically connected to the NFC control board 6 through the welding point 204 and the second spring contact welding point 205, forming a continuity detection circuit. The hexagonal lock cylinder 5 is installed in the hexagonal lock cylinder mounting slot 307 of the electronic lock cylinder 4. The two work together to form the limiting point 201, ensuring the mechanical positioning of the lock cylinder when it rotates. The first spring contact 202 of the first spring contact 9 contacts the metal surface of the hexagonal lock core 5, and the first spring contact welding point 203 is welded to the first spring contact mounting point 602 of the NFC control board 6. The second spring contact 10 welding point 205 contacts the metal part of the riveting sleeve 3, and the welding point 204 is welded to the second spring contact mounting point 601 of the control board. Together with the galvanized steel wire 1, the riveting sleeve 3, and the hexagonal lock core 5, they form a closed circuit. When the seal is not damaged, the circuit remains in a conductive state. The core processing unit 605 determines the seal status by monitoring the continuity of this circuit.

[0024] The NFC control board 6 is fixed inside the electronic lock body 2 by the support ribs 301. The electronic lock cylinder 4 has a battery compartment 302 inside, and the battery assembly 7 is installed in the battery compartment 302. The first spring contact 9 is fixed in the first spring contact mounting groove 304, and the second spring contact 10 is fixed in the first spring contact mounting groove 303 to ensure stable conduction with the galvanized steel wire 1. The NFC control board 6 is positioned and fixed by the support ribs 301 (protruding structure) on the inner wall of the electronic lock body 2 to avoid displacement caused by vibration. The battery compartment 302 inside the electronic lock cylinder 4 is used to accommodate the battery assembly 7. The battery connection cable 206 is connected to the battery assembly mounting seat 604 of the NFC control board 6 through the battery connection cable access point 207. Figure 6 The system is powered by the connection of the first spring contact 9 and the second spring contact 10. The first spring contact 9 and the second spring contact 10 are respectively embedded in the mounting slots 304 and 303 of the electronic lock body 2, ensuring tight contact with the surface of the galvanized steel wire 1 through the elastic pressure of the spring. Figure 4 The first spring contact groove 306 in the middle can maintain stable conduction even under vibration or external force, avoiding detection misjudgment caused by poor contact.

[0025] The first spring contact point 401 connects the hexagonal lock cylinder 5 and the first spring contact 9, and the second spring contact point 402 connects the riveting sleeve 3 and the second spring contact 10. A closed detection circuit is formed through the galvanized steel wire 1 to detect whether the seal has been damaged. The path of the closed detection circuit is: first spring contact point 401 (metal body of hexagonal lock cylinder 5) → first spring contact 9 → NFC control board 6 → second spring contact 10 → second spring contact point 402 (metal body of riveting sleeve 3) → galvanized steel wire 1 → hexagonal lock cylinder 5 (forming a closed loop). When the seal is installed normally, the galvanized steel wire 1 is taut and connected to all metal parts. If the seal is damaged (e.g., the galvanized steel wire 1 is cut, the lock cylinder is disassembled, or the contact is displaced), the circuit is broken, the core processing unit 605 detects the state change, and triggers an abnormal signal. This design realizes the linkage between physical damage and electronic detection, avoiding the defects of traditional seals that rely solely on mechanical structures.

[0026] The NFC control board 6 integrates a core processing unit 605 and an NFC chip 606 for detecting the seal status and exchanging data via NFC communication. The NFC control board 6 includes an NFC induction coil 603 and a battery component mounting bracket 604. The NFC induction coil 603 communicates with a mobile phone or handheld device, and the battery component mounting bracket 604 secures the battery component 7 and powers the core processing unit 605. The core processing unit 605 monitors the conduction status of the spring contact in real time and uploads data to the management platform via the NFC chip 606. The integration of the core processing unit 605 and the NFC chip 606 forms the core module for electronic detection and data interaction. The NFC induction coil 603, integrated on the control board surface, supports 13.56MHz near-field communication and can interact with NFC-enabled mobile phones or handheld devices (such as PDAs) without requiring an external power supply. The battery component mounting bracket 604 secures the battery component 7 (such as a button battery) and powers the core processing unit 605 and the NFC chip 606 via the battery connection cable 206, forming a semi-active design (low-power standby during normal operation, activated during communication). The core processing unit 605 monitors the conduction status of the spring contact at a preset frequency (e.g., once per second). When a circuit break is detected, the status data (e.g., damage time, device ID) is immediately uploaded to the management platform via the NFC chip 606 to achieve real-time electronic monitoring.
