Abstract

A container door electronic seal system for sensing abnormal opening/closing of a container door comprising a retainer, on which a locking rod installed outside the container door is seated, and a handle hatch, which binds or unbinds a handle seated on the retainer, according to the present disclosure, comprises: an electronic seal, which binds the retainer and the handle hatch, and which wirelessly transmits the abnormal opening/closing information of the container door to the outside; a first connector electrically extending from the electronic seal; a second connector, which is installed on the container door, and which is electrically connected to the first connector; and a first sensing unit electrically connected to the second connector to sense whether the handle hatch is opened/closed. According to the present disclosure, a sensing unit, which senses abnormal opening/closing of the container door, is installed on the container door and is recycled, thereby making it possible to implement an electronic seal system that can sense abnormal opening/closing of the container door with little costs.

Claims

1. An electronic seal system for a container door for sensing abnormal opening/closing of the container door, wherein the container door comprises a retainer on which a locking rod installed outside the container door is seated and a handle hatch which binds or unbinds a handle seated on the retainer,

wherein the electronic seal system comprises:

an electronic seal, which binds the retainer and the handle hatch, and which wirelessly transmits the abnormal opening/closing information of the container door to outside the container door;

a first connector electrically extending from the electronic seal;

a second connector, which is installed on the container door, and which is electrically connected to the first connector; and

a first sensing unit electrically connected to the second connector to sense whether the handle hatch is opened or closed; and

wherein

the container door further comprises;

a rotation shaft passed through the container door and extended to an inner side and an outer side of the container door;

a plate coupled to the rotation shaft extended to the inner side;

a lifting member rotatably coupled to the plate; and

a locking bar coupled to a lower side of the lifting member to lock or unlock the container door by being fixed to, or separated from a descending portion formed on a lower portion in a container,

wherein the first sensing unit comprises;

a magnet installed on the plate or the lifting member; and

a magnet switch configured to be turned on or off by the magnet installed on the plate to generate a signal corresponding to opening or closing of the handle hatch when the handle hatch is in the handle unlock position.

2. The electronic seal system of claim 1, further comprising a second sensing unit comprising a wiring installed on the locking bar that breaks together when the locking bar is broken.

3. The electronic seal system of claim 2, wherein the electronic seal comprises

an antenna, and

a RFID chip configured to sense, after electronic sealing is made, whether the handle hatch is opened or closed, whether the locking bar is broken or not, whether the electronic seal is released or not, and a connection state of the first connector and the second connector, and transmit, over the antenna, the sensed result according to an external request.

4. The electronic seal system of claim 3, wherein the electronic seal further comprises a light emitting unit configured to generate an alarm after electronic sealing is made, wherein the alarm corresponds to at least one of whether the handle hatch is opened or closed, whether the locking bar is broken or not, whether the electronic seal is released or not, and the connection state of the first connector and the second connector.
