摘　　要：采用面向对象和多线程技术设计,实现了软PLC编程系统软件在PC环境中进行梯形图的绘制、编辑、存储、加载、调试及仿真等功能。研究了梯形图程序存储与加载的实现方式和仿真模块中线程的应用,提出了一种编码规则表示控件,采用记事本格式存储程序。软件界面友好,用户操作方便,提高了PLC编程效率,方便了PLC的离线调试。The soft PLC programming system software was designed and implemented using object-oriented technology and mul- tithread technology. It was achieved to design, edit, save, load, debug ladder diagram and to simulate program run etc. in PC（Per- sonal Computer） environment. The thesis focused on realization of saving and loading ladder diagram programs and multithread tech- nology application in simulating module. A kind of coding rule was proposed to express controls, to save programs with notepad for- mat. It has friendly user interface, easy operation, which promotes efficiency of programming, and also facilitates PLC off-line de- bugging.
