基于ARM的编译型可编程序控制器系统研究

Research of the Compiled PLC System Based on ARM

可编程序控制器是电气自动化控制领域的重要组成部分,其性能的优劣对整个控制系统有着重大的影响。针对用户程序比较复杂时,采用编程指令的解释执行方式的PLC系统执行效率低、可移植性差等不足,提出一种基于ARM的编译型PLC系统构建方法,理论分析和测试实验都表明了这种方法的可靠性和高效性。

PLC,whose performance will directly affect the whole control system,is one of the most important parts of automation control domain.Aimed at low execution efficiency and bad transplantation of the system which uses the explanatory mode to execute its instructions,especially when some programs are complicated,a method of constructing a compiled PLC system instruction based on ARM was proposed.Both the theoretical analysis and testing experiment results show the reliability and efficiency of this method.
