With the increasing productivity, material for automated detection of inevitable. Based on the material analysis of the process flow, design based on the PC-PLC model material automatic sorting system of hardware of control system. Through the sorting system control system general scheme and working principle of introduction, elucidation of the control part of the hardware system design, completed the selection of hardware and software design, and through on-missioning verifies the rationality and reliability of the control system. Key Words: Stepping motor, control, PLC, material sorting 宁波大红鹰学院本科生毕业设计 5 目录摘要......................................................................................................................................... 3 Abstract ....................................................................................................................................... 4 目录......................................................................................................................................... 5 第1章绪论............................................................................................................................. 7 概述............................................................................................................................... 7 国内外的发展概况及趋势.......................................................................................... 7 本课题研
