Abstract

An item location tracking device having anti-theft function is provided. An item location tracking device having anti-theft function according to one embodiment of the present invention comprises: a tracker body comprising a sensing part and a communication module for transmitting information acquired through the sensing part to the outside, the sensing part including a magnetic force detecting sensor for detecting a magnetic field, and at least one state detecting sensor for detecting state information of an item; a container-shaped bracket having an insertion space into which the tracker body is inserted, and fixedly installed to an item so that the tracker body can be fixed to the item; and a permanent magnet disposed in the insertion space so that a magnetic field for detecting whether the tracker body and the bracket are separated from each other can be provided toward the magnetic force detecting sensor.

First claim

The invention claimed is:

1. An item location tracking device having an anti-theft function, comprising:
a tracker body comprising a sensing portion including a magnetic force sensor configured to detect a magnetic field and at least one condition sensor configured to detect condition information of an item and a communication module configured to externally transmit information obtained using the sensing portion;
a housing-shaped bracket which has an insertion space, into which the tracker body is inserted, and is fixedly installed on the item to fix the tracker body to the item; and
a permanent magnet disposed in the insertion space to provide a magnetic field toward the magnetic force sensor to detect whether the tracker body is separated from the bracket,
wherein the tracker body further comprises:
a lower cover which has an accommodation space with an open top and is detachably coupled to the bracket;
at least one circuit board on which the sensing portion and the communication module are mounted and which is disposed in the accommodation space;
a battery disposed in the accommodation space and electrically connected to the circuit board;
an upper cover configured to cover the open top of the lower cover; and
a control portion configured to control overall operations of the tracker body.

2. The item location tracking device of claim 1 , wherein when separation information between the tracker body and the bracket is sensed by the magnetic force sensor, the communication module externally transmits the separation information.

3. The item location tracking device of claim 2 , wherein the tracker body further comprises an alarm portion configured to generate an alarm sound when the separation information between the tracker body and the bracket is sensed by the magnetic force sensor.

4. The item location tracking device of claim 1 , wherein the condition information of the item includes one or more of position information of the item, information on whether an external shock is applied to the item, and temperature information, humidity information, and atmospheric pressure information of surroundings of the item.

5. The item location tracking device of claim 1 , wherein the item includes a mounting hole configured to fasten the bracket,
wherein the bracket includes at least one protruding portion formed on an outer surface to protrude outward therefrom, and
wherein the bracket is inserted into and embedded in the mounting hole to be prevented, by the at least one protruding portion, from being externally separated.

6. The item location tracking device of claim 1 , wherein the item includes a mounting hole configured to fasten the bracket, and wherein the bracket and the mounting hole are screw-coupled using mutually corresponding screw portions.

7. The item location tracking device of claim 1 , wherein the bracket includes a mounting groove configured to accommodate the permanent magnet, and wherein the mounting groove is defined by a guide portion formed to protrude from a bottom surface of the insertion space.

8. The item location tracking device of claim 1 , wherein in the bracket, at least one fastening hole for double fixation with the item is formed to pass through a bottom surface of the insertion space.

9. The item location tracking device of claim 1 , wherein when a magnetic force of the permanent magnet is sensed by the magnetic force sensor while the tracker body is coupled to the bracket, power is supplied to the tracker body to drive the tracker body.

10. The item location tracking device of claim 1 , wherein the bracket includes a plurality of guide grooves formed to be recessed from an inner surface along a height direction to allow an exclusive separation tool to enter.

11. The item location tracking device of claim 10 , wherein at least a portion of each of the plurality of guide grooves is cut to be elastically deformed by a pressure generated when the exclusive separation tool enters.

12. The item location tracking device of claim 10 , wherein the tracker body includes a holding groove formed to be recessed along a circumferential direction so that one side of the exclusive separation tool is held.

13. An item location tracking device having an anti-theft function, comprising:
a tracker body comprising a sensing portion including a magnetic force sensor configured to detect a magnetic field and at least one condition sensor configured to detect condition information of an item and a communication module configured to externally transmit information obtained using the sensing portion;
a housing-shaped bracket which has an insertion space, into which the tracker body is inserted, and is fixedly installed on the item to fix the tracker body to the item; and
a permanent magnet disposed in the insertion space to provide a magnetic field toward the magnetic force sensor to detect whether the tracker body is separated from the bracket, wherein the bracket includes a plurality of guide grooves formed to be recessed from an inner surface along a height direction to allow an exclusive separation tool to enter.

14. The item location tracking device of claim 13 , wherein at least a portion of each of the plurality of guide grooves is cut to be elastically deformed by a pressure generated when the exclusive separation tool enters.

15. The item location tracking device of claim 13 , wherein the tracker body includes a holding groove formed to be recessed along a circumferential direction so that one side of the exclusive separation tool is held.
