무선통신 기반의 화재 현장 사고자 탐색 시스템 모듈 = Fire Site Accident Search System Module based on Wireless Communication

다국어 초록 (Multilingual Abstract)

This study proposes an independent wireless communication-based search module to enhance victim search andrescue operations in disaster environments. For efficient data transmission, the system utilizes ultrawideband (UWB)and radio-frequency (RF) communication technologies. The proposed algorithm comprises both global and localsearches. Global Search employs radio frequency (RF) communication to identify the number of victims outside thefire scene, aiding evacuation planning. For real-time victim detection, Local Search utilizes UWB technology insidethe scene. The experimental results demonstrated the effectiveness of the module in improving victim search successrates and rescue speed and reducing rescuer movement distance. In smoke-free environments, the module achieved100% rescue success rate, reducing rescue time by 44.67%. In smoked environments, the module maintained a 100%success rate and decreased rescue time by 37.63%. The rescuer's total movement distance decreased by 7.84% and19.7% in smoke-free and smoked environments, respectively. This innovative system offers practical and efficientassistance to firefighters for locating and rescuing victims, reducing casualties, and enhancing disaster responseefforts
