Life jacket with location tracking device and distress rescue system using the same}

The present invention relates to a life jacket equipped with a location tracking device and a distress rescue system using the same. More specifically, in the event of a distress accident, it supports stable transmission of a rescue signal through the life jacket worn by the user and accurately identifies the person to be rescued. This relates to a life jacket equipped with a location tracking device that supports appropriate response and a distress rescue system using the same.

Currently, in preparation for distress accidents, sailors and passengers using ships wear life jackets, and in the event of a distress accident, they rely on the life jackets and wait for rescue before the rescue team arrives.

Recently, these life jackets not only protect the body of the person in distress, but with the development of various communication technologies and the terminals that support them, they are equipped with a built-in communication module and the function of transmitting a rescue request signal to the outside, through which the rescue request is requested. The organization receiving the signal is providing support for emergency rescue.

However, in most of these existing life jackets, the location of the communication module is built into the life jacket or fixed to a part of the life jacket, so when a rescued person enters the sea, most of the life jacket worn by the rescued person is submerged in water, which causes the life jacket to be damaged. The communication module provided is also submerged, and when the communication module radiates signals through the antenna, water absorbs most of the signals, resulting in the problem of impossibility of communication.

In addition, a stable power supply is required for the communication modules installed in the life vest to operate, and the manager in charge of the life vest must directly check and manage the remaining power of the battery that provides power to these communication modules. Therefore, multiple life vests must be used. Because it is difficult to check them individually, there is a problem that a significant number of life jackets are unusable due to battery discharge in the event of an actual disaster.

In addition, most of the rescue request signals transmitted from the communication module provided in the life jacket only transmit the unique identifier set in the communication module, so the rescue organization that receives the rescue request signal can secure the personal information of the person wearing the life jacket. There is a problem in that appropriate precautionary measures cannot be taken for victims due to difficulties in doing so.

Additionally, the control unit 140 of the distress device 100 may generate location information periodically or in real time when receiving a location request signal from the management server 300 and transmit it to the management server 300.

At this time, the control unit 140 of the distress device 100 may transmit the satellite number related to one or more satellites communicated when generating the location information by including it in the location information, and through this, the management server 300 may determine the satellite number. Based on this, precise location tracking can be supported by providing compensation for errors in location information.

In addition, after transmitting the location request signal, the management server 300 may match and store location information received from the distress device 100 periodically or in real time in response to the location request signal with the registration information.

At this time, the control unit 140 of the distress device 100 may include the code information for identification of the distress device 100 preset in the location information and transmit it, based on the code information included in the location information. After identifying registration information that matches code information included in the location information in the DB 301, the location information can be matched to the identified registration information and stored.

Through this, the management server 300 can track the location of each user wearing a life jacket based on the location information received from the distress device 100 for each life jacket, and determine the distress situation based on the location information. Alternatively, the distress situation is determined based on the rescue request information received from the user terminal 200, or the distress situation is determined by receiving the rescue request information from an external terminal, and when a distress situation occurs, each wearer (user) of a plurality of life vests The above-mentioned registration information including age, location, medical history information, biometric information, etc. can be provided, thereby supporting appropriate preemptive measures for each wearer.
