基于PLC的电解锌剥片控制系统设计

Design of Electrolytic Zinc Control System Based on PLC

摘要: 近年来我国经济的迅速发展，对于金属锌的需求量也在与日俱增。目前生产锌的企业采用了低水平的加工生产过程，导致锌产量不足，锌市场出现短缺，如何提高锌的生产效率成为电解锌生产行业关注的热点问题。传统电解锌生产过程中的剥片主要是通过手工完成，劳动强度大，生产效率低。电解锌的生产工艺经过多年的开发研究，相对成熟。本文结合电解锌后期处理的剥片生产工艺，提出以西门子可编程逻辑控制器S7-1200为控制核心，配备输入输出扩展模块、传感器、电机及驱动器等硬件，并选用组态软件实现系统的人机交互界面，完成了电解锌自动剥片电气控制系统设计。整个系统采用PLC为主控，上位机作为监控，减少了生产现场的操作人员，提高了电解锌的生产效率和品质。

Abstract: In recent years, with the rapid development of the Chinese economy, the demand for metallic zinc is also increasing day by day. At present, zinc production enterprises adopt low-level processing and production processes, resulting in insufficient zinc production and a shortage in the zinc market. How to improve the production efficiency of zinc has become a hot issue of concern in the electrolytic zinc production industry. The stripping process in traditional electrolytic zinc produc-tion is mainly completed by hand, which has high labor intensity and low production efficiency. The production process of electrolytic zinc has been developed and researched for many years, and is relatively mature. This article combines the stripping production process of electrolytic zinc post-processing, with Siemens programmable logic controller S7-1200 as the control core. The system is equipped with hardware such as input and output expansion modules, sensors, motors, and drivers. Configuration software is selected to achieve human-computer interaction, and the design of the automatic stripping electrical control system for electrolytic zinc is completed. The entire system adopts PLC as the main control and upper computer as monitoring, reducing the number of operators on the production site and improving the production efficiency and quality of electrolytic zinc.
