The invention discloses a multi-functional headset intelligent fire fighting system and a control method thereof. According to the multi-functional headset intelligent fire fighting system, a vibration-resistant platform is adopted to eliminate high-frequency vibration in the movement process of a fireman, an ultrasonic sensor makes up for the deficiencies of an infrared camera on deep information perception, and three-dimensional physical environment and temperature field distribution in a fire scene environment are calculated through a fusion algorithm; meanwhile, a combined sensor of GPS and inertial measurement and a magnetic field sensor are adopted, inertial movement information, magnetic field information and position speed information are fused, and information, such as a position, a speed, a posture and the like, relative to a node can be accurately acquired, so that a position and a direction of the node in a whole fire scene is assisted to be accurately established, and the three-dimensional physical environment and the temperature field distribution in the whole fire scene environment is established accurately by integrating various nodes; and in addition, by combining with historical data, optimal action strategy is obtained. The multi-functional headset intelligent fire fighting system accurately perceives the fire scene environment, rapidly analyzes a form of a fire and can perform intelligent decision, and thus own protection and efficient rescue and fire-fighting of the fireman is realized.
