摘　　要：针对自主可控可编程控制器上位机组态软件的梯形图编程需求,本文设计了一种梯形图语言编辑器。它基于QT下的图形视图框架,对接口进行了二次封装与扩展,实现了梯形图中各组件的创建、绘制与管理等功能。该梯形图编辑器已成功应用于和利时推出的新一代自主可控PLC编程软件平台,为PLC系统的梯形图逻辑组态提供了支持。In order to meet the requirement of ladder diagram programming in the configuration software of self-control programmable controller, a ladder diagram language editor is designed in this paper. Based on the Graph View Framework under QT, it encapsulates and extends the interface, and realizes the functions of creating, drawing and managing the components in the ladder diagram. The ladder diagram editor has been successfully applied to the new generation of PLC programming software platform which is launched by Hollysys, which provides support for ladder diagram logic configuration of PLC system.
