毕业设计(论文) 题目: PLC 在电镀生产线上的应用中文摘要 I 摘要电镀行车生产线自动化的程度在德国、意大利、美国等国家的发展水平已经较高,而在我国尚处于发展阶段。本课题以行业现状为出发点,结合其他行业自动控制技术的应用情况,提出了基于 PLC 的电镀行车自动生产线的设计,并通过应用机械、可编程序控制器(PLC) 等多项专门技术开发的自动生产系统。本文首先分析和制定了该生产线的整体设计思想和方案,确保了该生产线系统具备真正的自动化生产能力且结构简单。在该生产线的控制系统中,采用了高可靠性,高稳定性,编程简单,易于使用,而且广泛应用于现代工业企业生产线过程控制中的控制器 PLC 。重点分析了系统软硬件设计部分,并给出了系统主电路图、 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。关键词: PLC 、电镀生产线、控制系统、组态王 Abstract II Abstract Plating production line driving the degree of automation in Germany, Italy, the United States and other countries have higher levels of development, while in China is still in development topics to the industry status quo as the starting point, combined with other industry application of automatic control technology proposed PLC-based automatic electroplating production line design lane, and through the application of mechanical, programmable logic controller (PLC) and many other specialized technology developmentautomated production , analysis and development of the production line's overall design concept and programs to ensure that the production line automation system with real ability and a simple the production line control system, using a high reliability, high stability, simple programming and easy to use, and is widely used in modern industrial process control of production line controller PLC. Key parts of the system hardware and software design, and the system hardware, wiring diagram, PLC control I/O port allocation table and the overall program flow, etc., to achieve a plating production automation, improve productivity and reduce labor 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 pleted this system real-time monitoring system function, better caused this
