Fire-fighting evacuation system and method thereof

The invention relates to a fire-fighting evacuation system and an evacuation method thereof. The system comprises fire detectors, portable positioning devices and a server. The fire detectors are arranged in a building, and the position of the building on fire and a specific fire source position can be obtained via information of the fire detectors when outbreak of fire in the building is judged. Meanwhile, position information of portable positioning device carriers in the building on fire is acquired, and an optimal evacuation path for the portable positioning device carriers can be calculated according to information of the building on fire, the position information of the portable positioning device carriers, fire source position information and fire-fighting channel information. The fire source position can be effectively avoided by the optimal evacuation path, the nearest or safest fire-fighting channel and safety exit to the portable positioning device carriers can be rapidly found, and the optimal evacuation path is the customized optimal evacuation path for the portable positioning device carriers so that the fire-fighting evacuation system and the evacuation method thereof are high in evacuation efficiency and safe.
