智能化个体奶牛精确饲喂机设计与实验（Design and Experiment on Intelligent Precising Feeding Machine for Single Dairy Cow）
奶牛养殖 精确饲喂 射频识别技术
2009/12/28
要实现奶牛高产必须保证奶牛瘤胃pH值的稳定，要实现瘤胃pH值稳定必须对个体奶牛精饲料量进行精确饲喂，精饲料的数量对瘤胃pH值波动具有重要影响。设计了基于射频识别技术和单片机技术的个体奶牛精确饲喂机，可以实现个体奶牛精饲料量的精确饲喂。通过一个月饲喂实验表明，个体奶牛日产量提高了4kg。
精量饲喂系统的核心技术是奶牛个体识别技术。系统采用了非接触式的无线射频识别（RFID）技术，奶牛佩带符合ISO11785标准的电子标签。采食开始前，系统核对奶牛信息后按照饲喂要求进行自动投料。系统各测量数据将通过以ZigBee为核心建立起来的无线网络传输到主控计算机，同时主控计算机将奶牛饲喂规则的相关控制指令也通过无线网络传送到饲喂装置，控制饲喂装置工作。系统预留相关扩展接口方便后续升级使用。
奶牛体型评定三维图像同步采集系统（3D Synchronization Imaging System for Linear Appraisal of Dairy Cow Conformation）
奶牛 体型评定 三维图像
2009/5/22
设计奶牛体型评定三维图像同步采集系统，采用集散控制结构协调奶牛定位设备、图像采集装置按预定时序工作，应用3个CCD彩色摄像机与具有多通道、多独立图像芯片的DH—QP300型图像采集卡，实现了奶牛三维图像同步采集；采用LabVIEW软件作为采集主程序，通过调用动态链接库控制通用图像采集卡，选用场方式采集模式提高图像质量。试验证明，每头奶牛的图像采集与线性评定时间在3min左右,小于5min(标准)。...
