摘　　要：给进器是穿串机的关键硬件。针对控制难度较大的问题,研究一种基于机器视觉的小型自动穿串机给进器同步控制技术。分析穿串机给进器结构,构建机器视觉(摄像机)内、外参数模型,标定摄像机空间位置;采集给进器视觉图像,应用Roberts算子细化处理给进器视觉图像;基于PID原理设计模糊控制器,计算得到给进器同步控制模糊输出结果,完成肉块的自动穿串同步控制。实验数据表明:在不同实验工况下,应用提出技术获得的给进器同步控制时延最小值为2 s,穿串成功率最大值为96%。给进器同步控制时延较短,穿串成功率较高,控制效果更佳,进一步提升工作效率。Feeder,the key hardware of threading machine,is difficult to control.To overcome the difficulty,a machine vision based synchronization control technology for small automatic threading machine feeder is studied.The feed structure of threading machine is analyzed,the internal and external parameter models of machine vision(camera) are built,and the spatial position of the camera is calibrated.The visual image of the feeder is aquired and Roberts operator is applied to refine the visual image of the feeder.Based on PID principle,a fuzzy controller is designed,and the fuzzy output of feeder synchronization control is calculated to complete the automatic threading synchronization control of meat.The experimental data show that under different experimental conditions,the minimum value of feeder synchronization control delay obtained by the proposed technology is 2 s,and the maximum value of threading success rate is 96%.The synchronous control delay of the feeder is short,the threading success rate is high,and the control effect is better,which further improves work efficiency.
