The invention relates to the technical field of belt state detection, and particularly discloses a belt state detection method based on AI detection identification, and the method comprises the steps: belt deviation detection, deviation reason confirmation and feedback, belt wear detection, wear degree confirmation and feedback, and belt tear detection early warning. Whether the target belt deviates or not is judged according to the running video of the target belt, if the target belt deviates, the deviation reason of the target belt is determined, the abrasion degree of each area of the target belt is determined by constructing the three-dimensional information model of each area, meanwhile, tearing severity early warning is conducted by analyzing the tearing severity coefficient of the target belt, and therefore the tearing severity of the target belt is improved. The method improves the troubleshooting efficiency of belt deviation reasons, improves the accuracy of belt wear degree judgment, accurately evaluates the expansion direction and speed of cracks, provides effective data support for tear prevention and control, and helps to find potential tear risks in time, thereby reducing the possibility of belt tear accidents.
