Extremely early fire identification system and identification method of fire-fighting robot

The invention discloses an extremely-early fire recognition system and recognition method of a fire-fighting robot, and belongs to the field of fire fighting. A rotary holder is arranged on the robot; a fire-fighting lance, a visible light image detection module, a laser range finder and an infrared thermal imaging detection module are arranged on the rotary holder; during inspection of the fire-fighting robot, the rotary holder drives the visible light image detection module, the infrared detection module and the laser ranging module to rotate to detect the peripheral directions of the robot; the visible light image detection module, the infrared thermal imaging detection module and the laser range finder are used for positioning and tracking an abnormal high-temperature point, identification of the abnormal high-temperature point before fire and identification of an extremely early open fire behavior are achieved, and meanwhile the visible light image detection module keeps linkage with a fire-fighting lanc
