RESCUEE LOCATION DETERMINING SYSTEM UNDER OCCURRENCE OF DISASTER USING DRONE OUTSIDE BUILDING AND WI-FI ACCESS POINTS INSIDE BUILDING THROUGH RECEIVED SIGNAL STRENGTH INDICATION MEASURING METHOD

摘要

Provided is a rescuee location determining system under an occurrence of a disaster using a drone outside a building and Wi-Fi access points inside a building through a received signal strength indication (RSSI) measuring method. According to an embodiment of the present invention, the rescuee location determining system comprises: a drone outside a building having a Wi-Fi access point function, and approaching a building; a mobile device of a rescuee inside a building connected to the drone outside the building by Wi-Fi from the inside of the building, measuring an RSSI value between a plurality of Wi-Fi access points (hereinafter, referred to as first and second APs) in the building to obtain the distance from each Wi-Fi access point, measuring an RSSI value between Wi-Fi access points (hereinafter, referred to as a third AP) of the drone outside the building to obtain the distance from the third AP, obtaining a location of the rescuee inside the building which defines the drone outside the building as the origin by using the distances from the first, second, and third APs through a trilateration method, and then transmitting the same to the drone outside the building; and a drone controller of a rescue party outside a building for receiving location information of the rescuee inside the building from the drone outside the building.;COPYRIGHT KIPO 2017
