摘要在现代工业控制产业中，可编程控制器拥有不可以被替代的地位，主要是 因为它具有非常多的人性化的特点。可编程控制器也可以叫做一种融合了很多 种应用的小型的计算机。自从问世以后，就迎来了控制技术人员的青睐。72729

若要生产一件好的电镀产品，不仅取决于完善的电镀技术，同时还要严格 地根据电镀工艺流程运行。在电镀生产线上采用自动化控制不但可以提高企业 的生产效率和降低工人的劳动强度，还能够保障电镀产品的质量。而要想实现 自动化控制的关键就是对于行车进行自动化控制。在本篇设计中要实现行车的 前进后退以及吊钩的上升下降，要求不仅满足控制要求，定位也必须准确。在 其控制系统中我采用了 PLC 进行控制，它具有可靠性高，抗干扰能力强，编程 简单，功能完善等特点。我在这一篇设计论文中，着重描述了系统的硬件设计 和软件设计的内容，还绘出生产线的整体的流程图，I/O 口接线图、主电路图 以及电镀生产线 PLC 控制梯形图。我本次的设计可使整个的电镀生产线可以达 到较高自动化水平，从而增加产品的产量，也能够减少对于劳动力的投入成本。

Application design of PLC in electroplating production line

Abstract In today's industrial control industry, programming controller with position can not be replaced, mainly because it has the very many human characteristics, programmable logic controller (PLC) is in fact also a fusion of a variety of techniques of small computer。 Since since the advent, it ushered in the favor of control and technical personnel。

If you want a good plating products production, depends not only to improve the electroplating technology, but also strictly according to the electroplating process operation。 In the electroplating production line by automatic control can not only improve the efficiency of enterprise production and reduce the labor intensity of the workers, but also to safeguard the quality of electroplating products。 And to realize the automatic control of the key is for the automobile automatic control。 In this design to realize driving forward and backward and hook up decreased, requires not only to meet the control requirement, positioning must also be Accurately。 In the control system I used the PLC control, it has high reliability, strong anti-interference ability, simple programming, improve the functional characteristics。 This paper describes the hardware design and software design of the system, draw the production line of the overall flow chart, I / O port wiring diagram, main circuit diagram and electroplating production line PLC control program of ladder diagram and so on, so that the electroplating production line can reach a higher level of automation production, production efficiency has been improved and labor intensity。
