Abstract

Interest in mountain accidents among the technical trends of disasters in Korea is increasing continuously. When accidents occur, the most common methods are location tracking and accident reporting using smartphones, and rescue activities are being carried out by using them. In this paper, we proposed an improvement of wireless safety system for mountain climbing safety using 447 FSK. Using the 447 MHz band transmitter / receiver, it accumulates position coordinates and data through position transmission and rescue signal transmission in case of anomalies. If a sender is out of the threshold of the set area range, a danger warning notification can be generated to quickly exit the danger zone. Provide services. In addition, it is considered that the health condition of the sender is continuously checked and the receiver is warned when the specified threshold is exceeded, so that it is possible to respond to the sender's disaster.

국내 재난 사고의 기술동향 중 산악사고에 대한 관심 또한 지속적으로 증가 추세에 있다. 사고 발생 시 보편적인 방법으로는 스마트폰을 이용한 위치 추적 및 사고신고 등이며, 이를 이용하여 구조 활동을 진행 하고 있으나, 산악지역의 특성상 음영현상의 발생하는 구역에 대한 해결책이 요구되고 있는 실정이다. 이에 본 논문에서는 447 MHz 대역 FSK방식을 이용한 무선 통신 기반 산행 안전 휴대 시스템을 제시하였다. 447 MHz 대역 송·수신기를 이용하여 이상 현상 발생 시 위치 전송 및 구조 신호 전송을 통한 위치좌표 전송 및 데이터를 축적하며, 송신자가 설정된 구역범위의 임계치를 벗어날 경우 위험 경고 알림을 발생하여 위험지역을 신속히 벗어날 수 있는 서비스를 제공한다. 또한 송신자의 건강 상태를 지속적으로 체크하여, 지정된 임계치를 상위 할 경우 수신자에게 경고를 함으로, 송신자의 재난에 대응할 수 있을 것이라고 사료된다.
