基于PLC的电镀行车自动控制系统设计

摘 要

本设计利用日本欧姆龙PLC CP1E-E40DR进行电镀行车自动化控制。在本次设计中，从电镀行车在生产现场的运行环境和自动控制技术器件在国内的应用前景来考虑，以电镀行车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PLC来控制整个工作流程的方案。首先对系统的软硬件进行设计，给出系统的工作流程图、硬件接线图、PLC控制I/O端口分配表及整体程序流程图。并以CX-ONE为编程软件设计出电镀行车自动控制系统的梯形图，最后通过仿真实验，实现了电镀行车自动化控制，提高了电镀生产效率，降低了劳动强度。

Design of automatic control system of galvanization driving based on PLC

ABSTRACT

How did the article discuss has carried on the automated galvanization production line control using PLC CP1E-40DR, 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 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 with STEP7 Micro/WIN32 as the programming software designs has realized the galvanization production automation, reduced the labor intensity. In order to adapt the modern tradition industry control system, we also used based on the system had taken on the position machine.
