Abstract: Accelerometer motion sensor is widely used in animal behavior monitoring, which is an important direction of precision breeding research. This paper summarized the research of accelerometer motion sensor in animal behavior classification, introduced the wearable position of the accelerometer motion sensor on the animal body and compared the difference of its wearing in the legs and neck. The process of livestock behavior classification based on accelerometer motion sensor was discussed in detail, including the determination of sampling time window, feature vector extraction and classification algorithm construction. Automatic behavior classification was the preliminary and foundation for automatic monitoring and precision management of livestock. In the future, key technologies such as classification model construction, multi-sensor fusion and real-time data processing should be further broken through.
