嵌入式软PLC编程系统的设计

完成了一种在Windows操作环境下采用VC＋＋开发工具设计的嵌入式软PLC编程系统。采用面向对象的设计思想,提出了描述软PLC梯形图元件的数据结构,以及对梯形图元件集合存储和交互式的方案。该系统针对VC＋＋的Document/View的结构,设计了软PLC编程系统的软件结构,分为编辑、编译和仿真等功能模块,且结合相应的算法实现,并重点介绍了梯形图程序的编辑和编译扫描原理。为低成本高效率实现嵌入式软PLC编程系统提出了新方案,也为软件开发人员提供了一种软件设计的新思维。

Design of embedded soft PLC programming system

A sort of embedded soft PLC programming system using VC＋＋development tools in Windows operating environment is accomplished.This system brings a sort of data structure to describe soft PLC ladder-diagram components,and a proposal of storaging ladder-diagram collections and intertacing with them,which adopts object-oriented design idea.Thereby,according to VC＋＋ Document/View structure,the software stucture of soft PLC programming system is designed,which is divided into editing model,compile model and simulation model,and combines with the corresponding algorithm realization.The principle of editing and complier scanning emphatically is introduced.The realization for low cost and efficient embedded soft PLC programming system solutions provide a new thinking for the software developers.
