        摘要: 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。
        Abstract 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.
