This paper proposes a fire shunt guidance system model based on rule, it presents suitable shunt route in real-time according to collected fire information of the building inside using wireless sensor networks. So, this system model is composed of the sensor alert module, the behavior suggestion module, and the emergency device control module. The sensor alert module uses rule-base algorithm that monitored the information to collect periodically in wireless sensor networks. And, the behavior suggestion module proposed a suitable behavior, this module supports to judge the fire area with danger sensor list. Additional, the emergency device control module controls a related emergency device according to the suggested behavior and to present on a control screen. We experiment the fire shunt guidance system based on Internet Web for operation verification of the proposed system. Consequently, this study supports people safety with the behavior suggestion according to the context information when an emergency situation happens.

This study examined how the fire evacuation induction service system using a smartphone navigation application in the event of a fire affects the fire evacuation time, and the following conclusions were drawn. 1. The evacuation time was reduced by 22 seconds when the navigation application was used in computer scenario simulation. Even in the demonstration simulation, the evacuation time was reduced by 40 seconds when the navigation application was used. This indicates that the navigation application is effective in shortening the evacuation time in case of fire. 2. As a result of the demonstration scenario simulation, the time until the end of evacuation was 39 seconds faster in the case of evacuation guidance than in the case where it was not conducted. 3. No bottlenecks occurred in the evacuation route during the demonstration scenario simulation. As a result, there was a difference in the time required to complete the evacuation between the computer scenario simulation and the demonstration scenario simulation.

최근 들어 기후변화와 함께, 화재 발생이 증가함에 따라 인명피해와 경제적 피해가 늘고 있다. 화재 발생시 인명 피해를 줄여주는 소방시설 중 경보설비와 유도등설비는 위험 상황시 경보와 함께 동선을 유도하는 유도등을 보고 재실자들이 안전한 공간으로 신속하게 대피할 수 있도록 하는 소방설비 이다. 이중에서 유도등설비는 화재발생 상황에서 매우 중요한 역할을 맡고 있다. 특히 복잡한 동선을 가지고 있는 복합건물 및 지하철, 고층건축물에 신속한 대피 유도에 필요한 설비이다. 그러나, 화재 초기에 신속한 대피를 해야 하는데 5분도 되지 않아 화재로 인해 발생한 가스는 검은 연기로 유도등의 역할과 효과를 저해하는 현상을 가져온다. 즉 유도등의 녹색빛이 보이지 않는다. 이는 저시력자 또는 시력에 장애를 가지고 있는 자들은 더욱더 유도등을 확인하고 대피 하기란 쉽지 않게 된다. 이런 단점이 있는 기존의 유도등에 IoT(Internet of Things)와 함께 증강현실 이미지를 스마트기기에 활성화 한다면, 진한 검은연기로 인한 빛의 가림으로 인한 유도장애에 대해서 개선 할 수 있을 거라 생각되어, 변류기의 전류 감지를 시작으로 그 신호를 스마트기기에 녹색의 유도 이미지를 활성화하여 골든타임에 대피가 신속하도록 설비를 구현하여 그 가능성을 확인하였다.

In correctional facilities with majority of occupants in custody, the safe evacuation guide without getaway accidents should be very important due to complexity in escape paths. Fire causes are various in correctional facilities, for example, arson fire is a major cause in mental treatment facilities, however, old facilities or carelessness of flammable materials consist of fire causes in jail facilities. Both types of correctional facilities are the same in terms of many casualties from the fire cases. The thesis focus on escape paths and evacuation guide plans on the basis of analysis on fire cases and structural vulnerability, and then an electronic unlocking system is concededly installed for safe evacuation of occupants in custody without getaway accidents. Especially, the effect of the electronic unlocking system is going to be analyzed on the basis of RSET (required safe egress time) in order to realize for the occupants to evacuate safely to the front yard in case of emergency. In conclusion, if electronic security allowed system with USN (Ubiquitous Sensor Networks) technology should be installed in multi-storey correctional buildings, it is proposed that the occupants in custody might be a guided safely without getaway trials.

At the present time, buildings are designed higher and more complex than ever before. Therefore the potential disasters are happened such as fire, power outage, earthquake, flood, hurricanes. Their disasters require people inside buildings to be evacuated as soon as possible. This paper presents a new disaster evacuation guidance concept of inner buildings, whiche aims at integrated the constructing of a sensor network and a guidance light networks in order to provide a quick detection of disasters and accurate evacuation guidance based on indoor geo-information, and sends these instructions to people. In this paper, we present the integrated logical model based on sensor and guidance light networks for the fire disaster management in inner building using our concept. And we verify proposed logical model according to experiments with visualization and operations on map.

This study is intended to verify the efficiency of the information system by using the navigation application in case of fire. In the demonstration scenario simulation, it was assumed that a fire occurred 6th floor in Korea Institute of Industrial Design Promotion located in C city, K province. Eighty juniors students from K University's department of paramedics of science participated. As a result of the experiment, the demonstration simulation using the navigation application showed that the evacuation time was faster than the case of evacuation guidance in a fire situation. The need for a fire prevention system and fire prevention awareness before and after the implementation of the demonstration scenario simulation increased the need for a fire prevention system and fire prevention awareness score after the experiment.

This paper proposed that the method be searched for optimal route of evacuation by algorithm using potential field in specific situation, fire. When robot met an obstacle to be indicated it to ignition point, the installed sensor could be detected the point in restricted area. In according as the data of a fire detection sensor and a sensor complex in a building, the information was transmitted to server which computed optimal route of evacuation by algorithm using potential field. After that, it was able to blow a siren and mark the safe-path with using wireless device such as smart-phone. It was confirmed that the proposed method in functional test, fire emergency evacuation algorithm using potential field, was advanced in circumstance of simulation.

Based on the analysis of fire escape situations in public facility, this study was intended to propose a design of emergency light suitable for fire in public facility. A video analysis was conducted to understand the evacuation situation of public facility because the fire could not be randomized due to the disaster. Through video analysis, we were able to identify inconvenience and necessary needs in avoiding fire in public facility and reflected them in the design of emergency light, etc. As a result of the design of emergency light, the wall type induction lamp had different LED layout structures to minimize the thickness of the product. Ceiling induction lamps have been supplemented for additional installation in corridors of complex structures. The results of this study are designed based on the criteria used in the manufacture of actual emergency light and we intend to explore ways to be practical through further experiment measurements and complementary steps through expert advice.

재난 상황 발생 시 정보 습득이 어려워 시각장애인의 경우 초동대응 시간을 놓치게 된다. 특히나 화재사고 사상자 중 사망자 비중이 장애인은 비장애인에 비해 약 4 배 ~ 5 배 더 높으며 현재까지도 사상자가 발생하여 중요한 사회문제로 논의되고 있다. 본 연구에서는 기존의 스마트 대피 시스템의 한계점을 살펴보고 한계점을 개선할 수 있는 대안을 제시한다. 초동 시간 내에 사회복지사와 소방관이 사용자의 실시간 위치와 정보를 파악해 신고를 유도함과 동시에 자력 대피가 가능하도록 최적 대피 경로를 능동적으로 결정하여 안내방송을 출력하는 시스템을 소개한다.

소방청 국정감사에서 2020년 전국 자동화재속보설비 화재신고 32,764건 가운데 32,685건이 오작동으로 출동해 소방서 출동의 99.8%가 헛걸음이었다. 그리고 화재가 발생할 경우 화재경보장치와 대피경로를 안내하는 비상등이 미흡하고, 화재 연기가 제거되지 않아 대피가 힘들어질 뿐만 아니라 미처 대피 못한 인원을 파악하는 등의 신속한 대처가 힘들다. 본 논문은 화재 상황에서 피해를 최소화하기 위한 '스마트 화재 안전 시스템' 기술을 제안한다. 화재가 발생할 경우, 대피 경로를 안내하는 유도등 작동 및 경보음과 LED의 작동으로 화재발생을 경고하여 신속한 대처를 할 수 있게 도와주고, 문과 창문의 자동 개방 및 환기팬 작동으로 인한 유해가스를 환기시켜 준다. 그리고 스프링클러 작동과 소화제를 자동 분사하여 화재의 번짐 등 2차 피해를 예방하여 준다. 또한, 자동 신고 기능으로 더욱 빠르게 화재를 진압할 수 있게 도와주기 때문에 피해를 최소화할 것이다.
