摘　　要：文章设计奶牛活动量采集系统,通过三轴加速度计ADXL345采集奶牛X、Y、Z三轴加速度数据,经ZigBee无线网络和RS485传送至信息中心,应用K-均值聚类算法对其行为特征进行分类,分析一天内各行为特征所占时间比例,判断奶牛发情和身体异常等情况。该系统有助于实现奶牛的精细化饲养和健康养殖。The paper designed a cow activity data acquisition system. The system acquired cows X, Y, Z axis acceleration data by triaxial accelerometer ADXL345, sended the data to the information center by the ZigBee wireless network and RS485, applied the K-means clustering algorithm to classify their behaviors, analyzed the time scale of all behaviors in the day, and determined the cow estrus and physical abnormalities, and so on. The system contributed to achieve the refinement of breeding cows and healthy breeding.
