现代烟草工业控制系统越来越复杂,大量的工控机、大型PLC、各类总线、工业以太网、变频器和伺服系统应用到烟机设备,给电气管理维修人员提出了更高要求。掌握工业控制各方面的专业知识,尤其是工控中最基本最核心的PLC控制程序是关键。学习PLC程序需要不断地在实验平台上实践才能掌握,建立实验平台不但比较麻烦(需要很多的硬件和空间),还有很大的局限性,不足以满足全面学习PLC编程应用。基于西门子WINCC、STEP7及PLCSIM软件环境,搭建一个PLC虚拟培训实验平台代替复杂的硬件实物系统,让所有学习、编程、仿真实验均可在一台电脑里完成,可为电气维修人员提供一个PLC虚拟学习、培训环境。
Modern tobacco industry control system more and more complex, a large number of industrial machines, large PLC, all kinds of buses, industrial Ethernet, inverter and servo system applied to the hood equipment, to the electrical management and maintenance staff put forward higher requirements. Master all aspects of industrial control expertise, especially in industrial control of the most basic and core PLC control program is the key. Learning PLC programs need to constantly practice on the experimental platform to master, not only the establishment of experimental platform is too much trouble (requires a lot of hardware and space), there are still great limitations, not enough to meet the full application of PLC programming. Based on Siemens WINCC, STEP7 and PLCSIM software environment, build a PLC virtual training experiment platform instead of complex hardware physical system, so that all learning, programming, simulation experiments can be completed in a computer, electrical maintenance personnel can provide a PLC virtual Learning, training environment.
