Animal behavior detection method and device

The invention discloses an animal behavior detection method and device, and relates to the technical field of behavior detection. The animal behavior detection method comprises the following steps: collecting the motion data of an animal to be detected in real time by a motion sensor; according to the collected motion data, analyzing the motion vector direction and the motion trend of the animal to be detected; when the continuous and consistent motion trend of the animal to be detected are analyzed to reach a preset number of times and corresponding motion vector directions are the same, determining the appearance of a periodic action trend; comparing the characteristic data of the periodic action trend with the characteristic data of a preset action trend to obtain a matching degree of the periodic action trend and the preset action trend; if the matching degree is within a preset threshold value range, counting the number of times of the animal to be detected for continuous action behaviors generated in th
