ABSTRACT:
A system and method for detecting a fire includes a fire detection device and a control center terminal. The fire detection device includes an LRF for calculating a distance to a location of breakout of a fire using a laser. An infrared camera captures an infrared image and transmits the infrared image to a control unit. A CCD camera captures a CCD image and transmits the CCD image to the control unit. The control unit analyzes the infrared image, determines whether a fire has broken out, performs processing such that the CCD camera captures an area on fire, determines the location of breakout of the fire, performs processing such that the captured image is output to the control center terminal, and controls a function of a warning unit. The warning unit outputs a warning sound or a warning message.
