( 二〇一五年六月本科毕业设计说明书学校代码: 10128 学号: 201111202013 题目:基于 PLC 的电镀生产线运行控制学生姓名:李伟奇学院:电力学院系别: 电力系专业: 电气工程及其自动化班级: 电气 11-2 指导教师:白雪峰副教授内蒙古工业大学本科毕业设计说明书摘要本文探讨了如何利用德国西门子 PLC S7-200 进行自动化电镀生产线控制, 在本次设计中,我们从自动控制技术器件在国内的应用前景及电镀生产线生产现场的环境来考虑,以使该生产线真正具备自动生产运行为目的,制定了采用在当前及以后都应用广泛且能适应多种环境的可编程控制器来控制整个工作流程的方案。重点分析了系统软硬件设计部分,并给出了系统硬件接线图、PLC 控制 I/O 端口分配表以及整体程序流程图等,实现了电镀生产自动化,提高了生产效率, 降低了劳动强度。为适应现代传统的工业控制系统,我们还采用了基于组态王软件的系统作为上位机,配合下位机 PLC 完成了该系统的实时监控系统功能,更好的使该自动生产系统融入到现代工业控制领域中。内蒙古工业大学本科毕业设计说明书 Abstract This article discusses how to use Siemens PLC S7-200 automated control the electroplating production line, in this design, we consider the automatic control technology devices in the domestic prospects and electroplating production line environment in the field, so that the production line truly Auto production run for the purpose of developing a variety of environmental programs programmable controller to control the whole entire workflow using both current and future applications ina wide range and can adapt. It focuses on the hardware and software design part, and gives the system hardware wiring diagram, PLC control I/O port allocation table and the overall program flow chart, to achieve a plating production automation, improve production efficiency and reduce labor intensity. To meet the modern tradition of industrial control systems, we also adopted a system based Configuration software as a PC, with the next crew pleted the real-time monitoring system functions of the system, to better enable the automated production system into a modern industrial control field. 内蒙古工业大学本科毕业设计说明书目录引言……………………………………………………………………………… 1 第一章电镀的工艺和主要流程………………………………………………… 2 1. 1电镀工艺的…………………………………………………… 2 ……………………………… 2 ……………………………………………… 3 1. 4电力系统中性点接地方式……………………………………………… 3 第二章短路电流计算………………………………………………………… 5 ……………………………………………… 5 2. 2网络阻抗参数计算……………………………………………………… 5 ……………………………………………………… 10 ……………………………………………………… 13 2. 5接地短路电流计算…………………………………
