본 프로젝트에서는 화재 발생 시 발견하기 어려운 곳이나 화재가 빈번한 곳에 구축하는 것을 목적으로 하고 있다. 가스와 불꽃을 감지하는 센서로 화재를 감지하고, 디스플레이와 LED 그리고 소리를 통해 화재발생을 알려준다. 그 후, 스프링클러가 작동하여 초기화재에 대응에 도움을 주고 119에 자동으로 신고가 된다. 일정 수치의 센서에 대한 감지 값을 인식하고 인식한 감지 값에 반응하여 화재 대처를 가능하게 구현하는 시스템을 제안한다. 감지센서를 통한 화재장소에서의 불꽃과 가스를 감지하게 되어 스프링클러가 1차적으로 화재의 번짐을 지연해 주고 은근 소방서에 자동적으로 신고를 하게 되는 자동화 프로그램 이행을 목표로 하고 있다.

A fire detector installed in wood cultural properties has not have selected the detector type appropriate for the features of cultural properties and the structure of wood fire after the fire in Sungnyemun-Gate since 2008. Applying wooden cultural properties different from the general architecture of the structure and fire characteristics is difficult. Therefore, buildings were classified into four shape types and field survey and wooden architecture structure characteristics to identify the problems of the detectors installed on wooden cultural property buildings. The problems appeared to lack the adaptability to external fire detection sensor selection and missing fire detectors installed in accordance with the place. To solve the problem, the closed and open space of the rooms used a smoke detector, outdoor select flame or fixed temperature linear detector to solve the problem.

지금까지의 화재감지시스템은 하나의 입력요소에 대하여 화재, 비화재로 판단하는 단순한 형태의 신호를 발신하여 하나의 요소로만 화재를 판단하여 왔다. 또한 기존의 화재감지시스템은 화재 시에 발생되는 열, 연기, 불꽃 등에 대하여 감지기회로에서의 미리 지정한 고정값과의 비교를 통하여 정해진 기준을 넘을 경우 화재로 판정한다. 그러나 고정값을 기준으로 신호를 발신하게 되어있는 화재감지기의 동작은 상황에 따라 불확실한 경우가 발생한다.(중략)

In this paper, a design method to reduce fabrication errors in reflector shape of a test lamp for a flame detector is carried out. Although the test lamp should be operated in parallel with a high-intensity light, it is difficult to fix the small reflector that controls the central light during fabrication. To solve these problems, a small spherical reflector is designed to minimize the performance degradation for a light loss factor of less than 5%, even during tilt and decenter, and a spherical shape is proposed for a small reflector with little effect on the error when designing the optical system.

PZT ceramics, usually used pyroelectric materials exhibited a relatively highly Curie temperture(Tc) of $250-450^{\circ}C$ and permittivity constant of 500-1600. In this paper, the pyroelectric infrared detectors are applied two different types of pyroelectric materials, that is tetragonal crystal of ferroelectric $PbTiO_3$ and rhombohedral crystal of $Pb(Zr,Ti)O_3$. PZT ceramics shows not only highly Curie temperture but also excellent pyro and piezoelectric properties at the Zr/Ti(=52/48) ratio. Therefor in this paper, the pyroelectric infrared detectors are applied PZT ceramics, and obtained sensitive sensing characteristics by expriment case studies.

There is needed the triple pyroelectric Infrared flame detector to really recognize problem, for the prevention and early suppression of fire. This system recognizes the characteristics of fire sources in various type and is communicated the message to the operators. Therefore, the prevention and early suppression of fire is available. Especially this paper focuss on development of the self diagnosis type flame detector for preventing malfunction comparing of basic and detected values.

There is needed the quard channel triple wave lengths pyroelectric infrared flame detector to recognize the unique characteristics of fire sources in various type. This system detects the triple wave lengths of infrared flame emitting maximum radient energy and scattering frequency of flame. The quard channel infrared flame detector detects the duplicate wave lengths of maximum radient energy to enhance the accuracy of detecting fire. Especially this paper focuss on development of the self diagnosis function system including contamination, temperature and input voltage. Therefore, the prevention and early suppression of fire is available.
