洛阳理工学院毕业设计（论文） 基于PLC的电镀生产线控制系统的设计

基于PLC的电镀生产线控制系统设计

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。

Design of galvanization production line control system

based on PLC

ABSTRACT

How did the article discuss has carried on the automated galvanization production line control using German Simens PLC S7-200, in this design, we produced the scene from the automatic control technology component in the domestic application prospect and the galvanization production line the environment to consider, take caused this production line truly to have the automatic production movement as the goal, will formulate has used in current and later all applies widespread also can adapt the many kinds of environment programmable controller to control the entire entire work flow the plan.Has analyzed the system software and hardware design part with emphasis, and gave the system hardware wiring diagram, PLC has controlled the I/O port distribution list as well as the overall program flow diagram and so on, has realized the galvanization production automation, enhanced the production efficiency, reduced the labor intensity.In order to adapt the modern tradition industry control system, we also used based on the configuration king software system had taken on the position machine, coordinate lower position machine PLC has completed this system real-time monitoring system function, better caused this automatic production system to integrate to the modern industry control domain in.

KEY WORDS: PLC,Galvanization, Configuration King
