However, Korea is suffering from national trauma as it experienced maritime accidents such as the 'Sink of the Sewol ferry' in April 2014 and the 'Sink of the West Sea ferry' in October 1993.

In particular, the risk of marine accidents is because, unlike land accidents, once drowned in the sea, the survival time is extremely short due to hypothermia, which easily leads to fatal accidents, and there are many cases where they disappear due to currents and waves.

Therefore, even if a marine accident occurs and is in distress at sea, passengers wait for the rescue team to be rescued while wearing life jackets. The recently developed life jacket is equipped with a transceiver that transmits the location information of the victim to the outside for rescue. products are being distributed.

However, the conventional life jacket can continuously transmit a rescue signal to the outside until the rescue team arrives while maintaining the communication state in the sea relatively close to land, but communication becomes impossible in the sea far away from the land and the rescue team Emergency power is consumed before the rescuer arrives, and the golden time for rescue is often missed.

Therefore, in the present invention, the LoRa communication method is applied to the life jacket worn by the survivors to quickly identify and rescue the position of the survivors who are floating on the sea due to a sudden maritime accident, and the communication is relayed through the small ships nearby. In this way, we would like to propose a technology for a system that locates and rescues the victims. The following are prior art related to this.
