PLC梯形图编程软件实现

Implementation of PLC Ladder Diagram Edition Software

本文使用跨平台的C++应用程序开发框架(Qt)及其图形视图框架(The Graphics View Architecture)以及信号与槽机制,结合C++标准模板库中的链表结构、运行时类型识别等技术,实现了PLC梯形图编程软件的总体框架设计;梯形图语言的主程序、子程序、中断程序的存储及图元的插入编辑操作等功能。

This paper uses the cross-platform C＋＋ application development framework（Qt） and its Graphics View Architecture, as well as the signal and slot mechanism, combined with the C＋＋ standard template library linked list structure, run-time type recognition technology to achieve the PLC Ladder diagram programming software overall framework design; ladder language main program, subroutine, interrupt program storage and primitive insert editing operation and other functions.
