摘 要: 为克服传统可编程逻辑控制器(programmable logic controller,PLC)兼容性和可扩展性差、性价比低等缺点,同时为突破新型烟机设备PLC程序加密、二次开发难度高等问题,设计了基于嵌入式技术的ARM作为虚拟PLC以协助传统硬件PLC完成自动化控制。通过软硬件的设计及在Linux上定制功能,实现了该嵌入式软核PLC协同传统PLC在同一设备内共同控制的目标。因此,基于ARM嵌入式技术的PLC协同控制器消除了单一传统PLC控制的缺陷,具有体系结构开放、开发移植简单以及可扩展性高等优点,能较好地满足现代工业卷烟生产自动化的要求。
关 键 词: 自动控制技术;协同控制器;ARM;Linux系统;嵌入式可编程逻辑控制器

Abstract: To conquer the disadvantages of bad compatibility and extensibility and low performance cost ratio of traditionalprogrammable logic controller (PLC), and to make a breakthrough in the encrypted PLC program and the difficulty of secondary development in the new tobacco equipment, a new cooperative controller based on ARM as virtual PLC with embedded technology was designed. This cooperative controller could assist traditional PLC to complete the automation control. By the design of hardware and software, embedded soft-PLC assisted traditional PLC to control one equipment togetherafter function customization on Linux system was realized. The PLC cooperative controller based on ARM with embedded technology has overcome the shortcomings of traditional PLC,and had some advantages such as open system architecture, easy development, which can meet the requirements of modern cigarette production automation.
Key words: autocontrol technology; cooperative controller;ARM; Linux system; embedded programmable logic controller
