摘要
介绍了过程控制系统的组成和功能,并详细分析了模块之间数据传递方式。提出了系统软件的设计规划,建立了数据通讯与模型相分离的软件体系结构,简化了系统的调试和维护,易于扩展的设计使过程控制系结的适用性更强。
This paper introduces the composition and the function of process control system,and analyses data communication way among modules in detail.The design of the systems software has been proposed,and the software system structure that communication is separated from model has been set up.The mothod simplifies the debugging and maintenance of system, and has more e extensive suitability,
