The present invention relates to an electronic seal, in particular to a special electronic lock for electronic packaging which is specially sealed on the door panel of a container.

At present, about half of the containers transported by the port are transshipment containers. Because the port is roughly divided into several container centers, the re-export containers must be transported out of the port police inspection and registration station, and then transported to other container centers through the taxation area. In order to prevent the re-export containers from being smuggled and smuggled during transportation, the customs adopts manual escort monitoring for high-risk goods, but this approach virtually increases labor and shipping costs, and also causes inconvenience to the relevant operators.

In order to improve the above situation, the goal of replacing manual escort with technology in the port re-export container must have an electronic seal monitoring system that meets the international container sealing quality standards to be locked on the container to ensure the safety of the goods in the container. When the container is being transported, a signal can be sent through the electronic circuit of the electronic seal monitoring system when the goods in the container are stolen or wherever the container is being transported. Since the container usually takes a period of time to reach the destination, if the delivery time is too long, it is easy to cause the power consumption inside the electronic seal monitoring system to run out. Therefore, when the container arrives at the destination, the relevant unit or the owner needs to inspect the goods. It often happens that the electronic seal monitoring system cannot be opened by induction, so the electronic seal monitoring system needs to be destroyed before it can be opened, which will cause troubles in use.
