摘　　要：介绍了基于图像处理的给矿粒度检测及控制设计,给矿输送带上的矿石颗粒通过图像采集设备进行连续采集。对图像进行分析处理后,将统计结果输入PLC控制系统,控制系统通过与预设粒度值比较后,对摆式给矿机做出调整。该粒度检测系统能够连续输出矿石实际粒径,为磨机工作参数的最优控制和充分发挥磨机最大效能提供有效途径,并在攀钢某选厂进行实际应用,获得了较好的效果。Design of feeding particle size measurement and control based on image processing is introduced. The ores on feeding conveyor belt were captured continuously by image capture device.The statistical results obtained by analyzing and processing image were inputted into PLC control system,which then adjusted pendulum feeder when contrasted with predetermined size value. The detection system continuously output the actual sizes information,providing an effective way for optimal control of the working parameters and exerting the maximal efficiency of mills. As an example,the practical application of concentrator of Panzhihua Iron and steel obtained good results.
