최근 건축구조물의 복잡화, 다양화로 인하여 화재발생시 유독가스의 심각성과 공간의 특수성으로 인하여 대형 참사가 발생될 위험이 더욱 커짐에 따라 인명피해와 직접적으로 연결되는 피난탈출에 있어서 조속한 대책 마련이 시급한 실정이다. 기존 방식의 고정식 단방향을 표시하는 피난유도등은 효율적인 인명 대피 및 구조가 이루어지지 못하기 때문에 화재 발생 시 빠른 피난이 가능하도록 화재감지기와 연동하여 위험에 처한 피난자들을 탈출시키고 화재의 발생위치를 정확히 파악하여 초기 진압할 수 있는 시스템 구축이 절실히 요구된다. 이러한 점에 착안하여 ID를 가지는 화재 감지기 및 수신반과 연동하여 화재가 발생하면 화재가 발생된 방향의 반대 방향으로 모든 유도등의 방향을 제어하여 안전한 비상출입구로 사람들을 유도시키고 화염 및 연기의 방향과 속도를 계산하여 초기진압 및 최적 대피로로 방향을 표시하는 인공지능형 방향성 유도등 개발에 본 연구의 목적이 있다.

This study is intended to examine the effect of photoluminescent exit path markings in the event of failure of both the power and back-up power to the lighting and illuminated exit sign. To achieve the purpose, the test house was exhibited in Fire EXPO '05. 520 visitors were examined from May 26-29, 2005. The results of this study are as follows; The evacuation from buildings in dark conditions showed that 70% of men and 72% of women were crawled along the wall. Meanwhile, 88% of men and 83% of women were evacuated with ordinary walking in photoluminescent exit path markings. The photoluminescent exit path markings located on public buildings floors will aid in evacuation from buildings in the event of failure of the power to the lightings and illuminated exit signs.

We propose a shelter guidance system using the PLC to resolve that a conventional shelter guidance light for underground space has problems. The proposed shelter guidance system is composed of a main control part, a PLC remote control part, a charging part, a sound generation part, a display part, an alarm part and a smoke sensing part. The efficacy of the proposed system is verified by means of experimental. Experimental results are presented that show the effectiveness and the improvement of noise.

In case of an emergency such as a fire on a building and there is a need to evacuate the occupant in that building, it is important to have the guidance information effectively delivered to the evacuating occupants to guide them toward a safe direction using audio sensual media. And, it is also very important to prevent the evacuating occupants getting lost or falling astray, away from the direction toward safety. The purpose of this study, in this respect, is to examine the possible application of the precedent sound effect, with which the evacuating occupants may get a sense of the direction where the announcement comes from. With such an effect, an experiment was conducted to measure the extent to which people can hear the preceding and the following sound in terms of the acoustic pressure level changes and delay time changes, with a view to make the optimal evacuation-guidance announcement or sound. The optimal evacuation guidance sound (announcement) per each of the experimental indoors environments were as follows; 1) Regarding the optimal condition for the evacuation guidance announcement sound in the space of a lecture room, the direction of the advanced sound is positively recognized when the follow-up sound has the delaying time of 10 ms~50 ms in comparison with the advanced sound or when there is no difference between the acoustic pressures of the advanced and follow-up sounds or the acoustic pressure of the advanced sound is higher than that of the follow-up sound. 2) Regarding the optimal evacuation guidance announcement sound in the space of a hall, the advanced sound is positively recognized when the follow-up sound has the delaying time of 20 ms~60 ms in comparison with the advanced sound. 3) Regarding the optimal evacuation guidance announcement sound in the space of a gymnasium, the advanced sound is positively recognized when the follow-up sound has the delaying time of 10 ms~40 ms in comparison with the advanced sound or when the sound pressure of the advanced sound has a higher level than or the same level as that of the follow-up sound.

2003년 대구지하철화재를 보면 각종 대형 화재사고에서 법정 피난유도(유도등, 조명등)만으로는 화재 시 발생하는 연기 및 정전에 의하여 피난방향을 유도할 수 없음이 증명되었으며, 건축 계획적 측면에서의 안전을 확보하였다 하더라도 비상시 유도 설비들이 유도성능을 제대로 발휘하지 못 할 경우에 화재 상황으로부터 피난의 위험성을 가지고 있다고 할 수 있다. 따라서 소방 설비의 의존이 필요치 않은 자체적인 발광이 가능한 축광 안전용품이 필요시 하게 되었으며, 이에 현재 사용하고 있는 기존의 축광제품은 휘도가 떨어져 사실상 그 효과가 미미하며, 이 문제점을 해결하고자 지속발광 가능한 축광소재를 개발 하고자 한다.

If a disaster occurs in the underground like subway, disaster response system should minimize the casualties. It must quickly guide passengers to a safe evacuation route. But sometimes the system does not work properly. And then they need distributed disaster response system which make decision autonomously. In this study, we proposed the evacuation route analysis and induction algorithms for creationg passenger evacuation route and offering optimal evacuation route.

In case of a fire in urban large structures such as super high-rise buildings, evacuation guidance must be provided to the occupants in order to minimize human deaths and injuries. Therefore, it is essential to provide emergency evacuation guidance when a major fire occurs. In order to effectively support evacuation guidance, it is important to identify major items such as fire location, occupant position, escape route, etc. Also, it is important to quickly identify evacuation areas where residents can safely evacuate from a fire. In this paper, we analyze the CCTV video and propose a method of measuring visibility of the evacuation zone from the smoke caused by the fire in order to determine the safety of evacuation area. To do this, we first extract the background video from the smoke video to measure the visibility of the specific area due to smoke. After generating an edge-extracted image for the extracted background video, the degree of visibility is measured by calculating the change in the edge strength due to smoke.
