AI Technical Summary
Existing anti-theft mechanisms for containers, such as disposable plastic seals and bullet seals, fail to provide real-time notification of theft, and existing electronic locks lack the ability to detect electrical disconnection of the lock cable, which is crucial for determining if the lock has been tampered with.
An RFID-based electronic tag lock with a control circuit board that detects and records electrical disconnection of the lock cable, utilizing a clamping mechanism with movable clamping components and an elastic component to secure the cable, and a radio frequency unit to trigger alerts upon disconnection.
Enables real-time detection of tampering by monitoring electrical continuity of the lock cable, ensuring immediate notification of unauthorized opening and enhancing security through reliable cable retention.
Description
TECHNICAL FIELD
[0001] This application relates to an electronic tag lock.BACKGROUND
[0002] Currently, transporting goods through containers is becoming more and more common, which also puts forward higher requirements on the management of containers. At the existing technology, the anti-theft marking of containers is generally done by adding disposable plastic seals or bullet seals to the keyholes of the container to mark that the container has not been opened. However, disposable plastic seals or bullet seals cannot notify the theft of container in time, and only serve as a reminder after the event, and thus cannot notify the owner of the container in time.
[0003] Patent literature (CN106530950A) provides an antitheft electronic tag with a replaceable antitheft cable. A first conductive connector and a second conductive interface which are suitable for being connected in a clamping manner are arranged at the two ends of the antitheft cable; and a first conductive elastic access part and a second conductive elastic access part, a first clamping part of the first conductive connector and a second clamping part of the second conductive connector are arranged in a tag shell.
[0004] Patent literature (CN211691907U) provides a fingerprint anti-theft lock. The fingerprint lock comprises a locking piece, a lock shell fixed to one end of the locking piece, a fingerprint unlocking mechanism and a locking mechanism, the other end of the locking piece is provided with a lock head for locking of the locking mechanism, the lock shell is provided with a locking hole for insertion of the lock head, the locking mechanism comprises a fulcrum structure and a supporting rod, the supporting rod is provided with a clamping part, and the fingerprint unlocking mechanism recognizes fingerprints and can drive the clamping part to swing around the fulcrum structure to lock or unlock the lock head.
[0005] Patent literature (CN109138651A) discloses an RFID steel wire rope type electronic lock which includes a lock body and a steel wire lock rope. A first channel and a second channel are arranged in the lock body, and a groove for containing a bracket is formed in the middle of the lock body. The bracket is provided with a chute for containing a clamping wheel, and a round hole for containing a spring. The clamping wheel is pressed into the second channel by the spring. An insulating bush is contained in the first channel of the lock body. A hoop is disposed outside the lock body and connected with a first connecting sheet. The tail end of the steel wire lock rope is sleeved with a step-shaped insulating bush and a cylindrical hoop. The steel wire lock rope and the lock body are separated by the insulating bush. The steel wire lock rope is inserted in the second channel and jacks the clamping wheel, and meanwhile, the steel wire lock rope is tightly locked by the clamping wheel under action of the spring so that the steel wire lock rope can only be inserted instead of retracting or being pulled out. The tip end of the steel wire lock rope is connected with a second connecting sheet after penetrating through the second channel, so that the first connecting sheet and the second connecting sheet communicate. The steel wire lock rope plays a role in passage in the sealing process. The lock is suitable for the sealing condition of various occasions and is an all-weather electronic lock.
