[0001] CALL DEVICE FOR LOSS PREVENTION RECEIVER [0002]

The present invention relates to a loss prevention receiver calling apparatus, and more particularly, to a loss prevention receiver configured for each of a plurality of personal items so that when a user makes a call by pressing a number formed in a call control unit, the loss prevention receiver generates an alarm The present invention relates to a device for calling a loss prevention receiver which makes it possible to easily recognize a corresponding position by calling a loss prevention receiver even through a smart device which is always carried.

A system for preventing the loss of a mobile phone using Bluetooth is well known. The system includes a transmitter that is installed in a cellular phone and transmits a 2.4GHz Bluetooth RF signal at regular intervals, and a receiver that receives a signal transmitted from the transmitter.

If the receiver fails to receive the Bluetooth RF signal transmitted from the transmitter for a predetermined period of time, the receiver determines that the communication effective distance of 5 meters has been deviated and notifies the user of the loss of the mobile phone by way of an alarm sound,

Therefore, if the user recognizes that the receiver has lost the cell phone, the cell phone is not lost.

However, if the user does not immediately notice the receiver's mobile phone loss notice and after a considerable time, recognizes the fact that the mobile phone is lost from the lost place, it is very difficult to find the lost place and it becomes very difficult to retrieve the mobile phone again.

In addition, since the receiver only provides a notification of loss to only one mobile phone, it can not provide a lost notification service for personal items other than the mobile phone.

Also, if the user loses the receiver rather than the mobile phone, he can not receive the lost notification service for the mobile phone.

The above-described technology operates when the user is away from a certain distance, and can not immediately confirm his / her location if people with severe forgetfulness lose their personal belongings.

For example, if you are forgetting your cell phone, car keys, remote control, wallet, etc. at home, you should look for a sofa, bed, drawer, etc. to find it.

In general, a location tracking device is a device used for identifying a current location of a person who has a terminal. Examples of the location tracking method include a cell ID method, a GPS method, (TDOA: Time Difference Of Arrival) scheme.

The cell ID method is a method of locating a cell or a sector providing service to a mobile switching center that manages a terminal, and the accuracy is in proportion to the radius of the cell.

The GPS is a method of measuring the time and distance from three or more satellites by a receiver and calculating the current position of each of the three distances using a triangular method.

The TIDIO method is a method of tracking a location using a time difference of a signal arrival time between a mobile switching center and base stations.

In order to prevent the pet from being stolen or lost, commercially available products such as a necklace, a bracelet, etc., or a simple name tag attached to the chest or sensor It is only a device that causes the alarm to be generated when the guardian and the protected person are separated by more than a predetermined interval using the device.

However, the above-mentioned product has a problem in that it is unable to actively wait for the position to be tracked merely by manually waiting for the report of the discovery of the lost pet when the actual pet is lost.

Also, due to the nature of the pet, when the owner is not around, it becomes psychologically unstable, which causes considerable stress, which can cause unexpected accidents.

Due to such a problem, development of a verification apparatus using a location tracking method such as a GPS is being attempted.

However, the conventional confirmation device merely provides the current location, so that it is impossible to appropriately cope with an unexpected emergency situation because it is impossible to confirm information about the specific building in which the building is located and what situation is occurring .
