  • This study is based on the principle of solar power system and fire breakout. The result of the survey indicates that a solar power system is vulnerable to fire due to lack of maintenance after the installation. Currently the national fire safety agency does not have standards and legal provisions for the installation and maintenance of solar power facilities. Therefore, it increases the risk of fire breakouts as well as possibility of electric shock for the firefighters during fire fighting. This results possible damages to the human and equipments. In this study is proposing an automatic fire extinguishing system to reduce the power generation of solar panels during fire breakouts. Also, propose an over load current alarm system and fire prevention measures for fire fighters. The results of this study will be used as basic data for further fire testing of solar power systems.

  • Instruction and prevention of the safety for a fire have been performed continuously by nation. However, the accident due to a fire is not decreasing and causes a serious calamity to people. It is at the initial stage of fire burning that the most effective way to reduce damage is to evacuate and fight a fire. When a fire burns, the equipments reporting to other person or organization concerned are called 'acoustic reporting equipment'. Among those equipments reporting to person, 'a fire bell' is the easiest equipment to approach. Observing the behaviors of people when a fire burning, some are in a quiet indoor, some in a room with other people, some in a square with many people and some in indoor filled with smoke etc. This study aims to find out an acoustic reporting signal appropriate for visual information. For the experiments, visual-auditory experiments were performed through reporting signals and visual informations with several situations that is able to be faced at when a fire burns.

  • The prevention of disasters in cultural property is very important management and historical duties. The reason can't be measured values with monetary scale of our contemporary. Therefore, this paper was considered fire-safety as one of terrible threat-disasters about the wooden buildings. This research deal with 47 cases cultural property wooden building by whole investigation(field survey and interview) in Gangnung province. The most buildings have basic fire extinguisher; ABC powder. A few buildings are rarely installed fire extinguishing equipments; outdoor fire hydrant, heat sensor, ground sprinkler, CO2-hose-reel. But these state is very insufficient for the fire-safety in cultural property wooden buildings. Specially as particular attention in province, forest fire of regional characteristic have close relation with cultural property fire. The majority of factor against forest and building fire is to provide monitoring and security system; CCTV, Fence, Sensor, Alarm and paid guard man against incendiary. Ultimately it is necessary to construct comprehensive disaster prevention system with the organic cooperation such as National Emergency Management Agency, Cultural Heritage Administration, Forest Service, local government officials and regional citizen.

  • 본 연구는 주거용 건축물에 설치하는 단독경보형감지기와 소화기의 보급률의 문제점과 개선대책을 제시한 연구이다. 국가화재정보시스템의 통계 자료에 의하면 최근 8년간 전체 화재의 18%, 사망자의 45%가 주거용 건축물에서 발생한 것으로 나타났다. 그런데도 2019년 현재 주거용 건축물에 설치하는 기초 소방시설의 보급률은 60%에도 도달하지 못하였다. 이에 본 연구에서는 화재 안전에 대한 대책의 수립을 위해 관련 법령 및 화재 발생 현황을 분석하였다. 그리고 첫째 60세 이상의 노인 계층 및 소방차량 진입 곤란 지역의 재난 약자를 대상으로 무상보급, 둘째 재난 취약계층을 위한 재난 안전 수당의 도입, 셋째 공인중개사법의 개정을 통한 보급 확대, 넷째 각종 안전교육을 통한 기초 소방시설의 자율적 설치유도 및 Data base system의 구축을 통한 기초 소방시설의 보급률 증가, 다섯째 공동주택 국가 화재안전기준의 제정을 제안하였다.

  • An arc/spark detector (ASD) was developed is to early detect wire failures and insecure connections that may lead to fire in residents and commercial and industrial facilities. A detailed circuit design for ASD implementation along with prototype product is reported. The tests of ASD, which were successful in phase identification, in many different arc/spark locations under different loadings, and in false alarm probability, showed the ability and capability of the state-of-the-art detector in the electric fire hazard prevention.

  • 건물내의 열을 온도 센서를 통해 모니터링함으로써 발생되는 온도 데이터의 양은 온도 센서의 정밀도가 향상되고 센서의 수가 증가함에 따라 기존의 화재감시시스템이나 공기조화냉동시스템에서 발생하는 것과는 비교할 수 없이 증가하게 된다. 이 과정에서 화재를 감시하기 위하여 유용한 데이터만을 처리해 데이터베이스화하고, 화재 예방에 활용하기 위해 온도 데이터의 효과적인 처리 방법을 연구함으로써 보다 작은 시스템의 구축으로도 안정적인 화재 감시 및 예방이 가능한 방안을 제시한다.
