摘  要:针对豆荚类农副产品挑选过程中存在劳动强度大、自动化程度低、人力需求多而导致生产成本过高的问题,运用计算机等智能控制技术建立了由物料输送机构、图像采集装置、图像处理系统、光电开关、PLC、电磁阀、高压气嘴、洁净压缩气源等组成的豆荚类农产品智能挑选系统,着重研究了豆荚类农产品智能挑选PLC控制系统的结构和原理,研制了原理试验装置,并在生产现场进行了实际测试。当图像处理系统成功获得图像并处理完成,得到识别判断信息后,向PLC控制系统发出信息指令,控制系统在及时接收上位机所发信息指令后,准确控制电磁阀开启,使得气嘴喷出高压洁净气体并有效地把需要分离的物料移除。原理试验装置测试结果表明,该豆荚类农产品智能挑选系统测试准确率达95.67%。Aiming at the pod kind of agricultural by-product high cost problem which is led by low automation and the need for more people, intelligent selection system for pod kind of agricultural by-product was designed. This system was composed of material conveying mechanism, image acquisition device, an image processing system, photoelectric sensor, PLC, electromagnetic valve, high pressure nozzle and clean compressed air. The test device based on the system was designed and made. In the practical application process, the conveying mechanism, the image acquisition device and a series of valves were controlled automatically by the system. The required material was removed effectively by the high pressure gas erupted from the air cock. The results indicate that the precision of this automation technology for the selection of the kind of agricultural by-product can get 95.67%.
