摘　　要：为了解决羊只称重困难问题,在不影响羊群正常通行的前提下实现在自然状态下对羊群体重的日常监测,减小羊只的应激反应,试验设计了一种羊群无感知体重监测系统,以STM32单片机为核心控制器采集数据并传给上位机,原始数据经滑动平均滤波法、随机森林算法、平均差系数法处理后得到每只羊的体重,并对该系统进行了验证。结果表明:羊群无感知体重监测系统对羊只体重监测结果的相对误差小于1.5%,绝对误差小于1.00 kg,符合实际需求。说明羊群无感知体重监测系统可应用于畜牧生产中的羊体重监测。In order to solve the difficult problem of sheep weighing,to realize the daily monitoring of sheep weight in the natural state without affecting the normal passage of sheep,and to reduce the stress reaction of sheep,a sheep non-perceptual weight monitoring system was de⁃signed.STM32 microcontroller was used as the core controller to collect data and transmit them to the host computer.The body weight of each sheep was obtained by processing the original data with sliding average filtering,random forest algorithm and mean difference coefficient me⁃thod,and the system was verified.The results showed that the relative error and the absolute error of the sheep weight monitoring results ob⁃tained by the sheep non-perceptual weight monitoring system were less than 1.5%and less than 1.00 kg,respectively,which could meet the practical requirements.It indicated that the sheep non-perceptual weight monitoring system could be applied in the the research of animal weight monitoring system in livestock breeding production.
