MONITORING DEVICE AND MOVEMENT DETECTION METHOD

摘要

A first acquisition unit 201 acquires acceleration information from a sensor attached to the neck of an animal. A second acquisition unit 202 acquires individual information pertaining to the individual animal. A detection unit 203 detects that the movement of an animal is a body-shaking or scratching movement, when the change over time in the strength of acceleration expressed by the acceleration information indicates that the frequency of a peak having a peak strength equal to or greater than a first threshold is equal to or greater than a second threshold. The detection unit 203 uses values determined according to the acquired individual information for both the first threshold and the second threshold. A determination unit 204 determines whether the health of the animal is good or bad on the basis of the movement history detected by the detection unit 203. A notification unit 206 notifies a prescribed destination when the determination unit 204 determines that the health of the animal is bad.
