ANIMAL TAG FOR MONITORING ANIMAL BEHAVIOR

摘要

Animal behavior is monitored via first and second sets of sensors (210; 220) in an animal tag (200). The first set of sensors (210) repeatedly produces a first amount of data (D1) representing a movement vector (Mxyz) of the animal tag (200) relative to a fix reference frame (x, y, z). The second set of sensors (220) produces a second amount of data (D2(1), D2(2), D2(3)) representing micro movements of the animal tag (200) with respect to an orientation (Οαβγ) relative to the fix reference frame. A processing unit (230) receives the first and second amounts of data (D1, D2(1), D2(2), D2(3)), and based thereon determines a behavioral status of an animal (A) that carries the animal tag (200). The processing unit (230) also controls (C2(1), C2(2), C2(3)) at least one sensor (221, 222, 223) in the second set of sensors (220) to be active or inactive based on the movement vector (Mxyz) represented by the first amount of data (D1). Thus, the energy resources in the animal tag (200) can be economized.
