A wireless acceleration measurement system was applied to free-moving cows and horses. Sensors were available as a collar and a flat box for measuring leg or trunk movements. Results were transmitted simultaneously by radio or stored in an 8-MB internal memory. As analytical procedures, frequency distributions with standard deviations, spectral analyses, and fractal analyses were applied. Bymeans of the collar sensor, basic behavior patterns (standing, grazing, walking, ruminating, drinking, and hay uptake) could be identified in cows. Lameness could be detected in cows and horses by means of the leg sensor. The portion of basic and harmonic spectral components was reduced; the fractal dimension was reduced. The system can be used for the detection and analysis of even small movements of free-moving humans or animals over several hours. It is convenient for the analysis of basic behaviors, emotional reactions, or events causing flight or fright or for comparing different housing elements, such as floors or fences.
一种无线加速度测量系统被应用于自由活动的牛和马。传感器有项圈式和平板式两种，用于测量腿部或躯干的运动。结果通过无线电同时传输，或存储在8兆字节的内部存储器中。作为分析程序，应用了带有标准差的频率分布、频谱分析和分形分析。通过项圈传感器，可以识别奶牛的基本行为模式（站立、吃草、行走、反刍、饮水和采食干草）。通过腿部传感器可以检测牛和马的跛行情况。基本和谐波频谱成分的比例降低；分形维数降低。该系统可用于检测和分析自由活动的人类或动物在数小时内的微小运动。它便于分析基本行为、情绪反应或导致逃跑或惊吓的事件，或用于比较不同的居住元素，如地板或围栏。
