The present invention relates to a fire detection system, in which an existing P-type/R-type fire receiving panel which does not provide fire detection information in the form of digital information is photographed by a camera and converted into digital information through image analysis, and mapped to a digital map to be displayed on a screen. The fire detection system includes: the camera for photographing the fire reception panel including one or more indicators which are turned on through an analog signal transmitted from one or more fire detection sensors for each area to be controlled; a control unit which analyzes an image obtained from the camera to extract the area where the indicator is turned on, finds the location information indicated by the indicator mapped to the extracted area from a database, and generates digitized fire detection information; and an output unit which visualizes and outputs digitized fire detection information transmitted from the control unit on a digital map. 본 발명은 화재감지정보를 디지털정보 형태로 제공하지 않는 기존의 P형/R형 화재 수신반을 카메라로 촬영하여 영상분석을 통해 디지털정보로 변환하고, 디지털 지도에 매핑하여 화면에 표시하는 화재 감지 시스템에 관한 것으로, 하나 이상의 관제 대상 영역별 화재감지센서로부터 전달되는 아날로그 신호를 통해 점등되는 하나 이상의 표시등을 포함하는 화재 수신반을 촬영하는 카메라와, 상기 카메라로부터 획득되는 이미지를 분석하여 표시등이 점등된 영역을 추출하고, 그 추출된 영역에 매핑되어 있는 표시등이 나타내는 위치정보를 데이터베이스로부터 찾아 디지털화된 화재감지정보를 생성하는 제어부 및 상기 제어부로부터 전달되는 디지털화된 화재감지정보를 디지털 지도상에 가시화하여 출력하는 출력부를 포함함을 특징으로 한다.
