The present invention relates to a container opening detection device and method for detecting and informing illegal opening to an external reader.

Currently, container transportation is mostly connected with land and sea, and accordingly, the container terminal is located around the port, and sufficient facilities and organization are available for unloading operation and management and storage of various related equipment. This is necessary. In addition, a land and sea transport system with the ability to handle large numbers of containers quickly should be balanced and smooth.

Box-type containers used for the efficient and economical transport of large or small-sized cargoes can be easily transported general and special cargo without external packaging, saving time and money. In addition, it is designed to prevent accidents that may occur during transportation, such as damage, loss and theft of cargo.

FIG. 1 is a view illustrating a door locking device installed in a conventional container. In the rear of the container 100, two doors 120 that open the door 110 to both sides are installed to be rotatable by a hinge. The door lock device 130 for locking the door 120 of the doorway 110 is installed at both sides of the center of the door 110, and the door lock device 130 moves up and down while rotating the handle 131 of the door lock device 130 to set or open and close the door.
