ELECTRONIC SEAL DEVICE AND METHOD OF SENSING OPENING USING THE SAME
First Claim
1. An electronic seal device, comprising:
- a T-shaped bolt unit including a protrusion formed to protrude from a first side thereof at a predetermined thickness to provide directionality, the bolt unit configured to transmit unique data as a Radio Frequency (RF) signal; and
an electronic circuit unit including a groove formed in the wall of a hole therein to provide directionality so that part of a shank of the bolt unit is inserted into and engaged with the hole to a predetermined depth, and a drainage hole formed in a lower portion of the electronic circuit unit, the electronic circuit unit configured to transmit/receive RF signals to/from the bolt unit.

Abstract
Methods and apparatus are disclosed for sensing opening of an electronic seal device. According to one embodiment, the electronic seal device includes a T-shaped bolt unit including a protrusion formed to protrude from a first side thereof at a predetermined thickness to provide directionality, the bolt unit transmitting unique data as a Radio Frequency (RF) signal; and an electronic circuit unit including a groove formed in the wall of a hole to provide directionality so that part of the shank of the bolt unit is inserted into and engaged with the hole to a predetermined depth, and a drainage hole is formed in a lower portion of the electronic circuit unit, the electronic circuit unit transmitting/receiving RF signals to/from the bolt unit.

7. A method of sensing opening using an electronic seal device, comprising:
-
a first step of storing unique data about a bolt unit, acquired using an initial RF signal, transmitted between the bolt unit and an electronic circuit unit, in a storage unit of the electronic circuit unit; a second step of a control unit determining whether a predetermined time has elapsed after the unique data about the bolt unit is stored in the electronic circuit unit; a third step of checking unique data about the bolt unit using RF signals if it is determined that the predetermined time has elapsed as a result of the determination of the control unit; and a fourth step of determining whether the unique data about the bolt unit, checked using the RF signals, is identical to the unique data about the bolt unit, stored using the initial RF signal, through data comparison after the predetermined time has elapsed, and returning to the second step of determining whether a predetermined time has elapsed if it is determined that the checked unique data is identical to the stored unique data. - View Dependent Claims (8, 9, 10, 11)
