基于QT的PLC梯形图编辑系统设计与实现
|
摘要
为了探索PLC梯形图编辑系统的设计方法,从梯形图编程系统设计需求出发,分析传统梯形图网络的不足,采用一种高自由度的网络拓扑结构描述梯形图网络,并根据该网络拓扑结构提出一种分布式存储方案,实现梯形图图元之间的连接关系存储。基于QT图形框架采用面向对象的软件方法实现梯形图标准图元创建、连接关系建立、图元删除等功能。完成梯形图编辑系统设计后,对图元管理、各种指令调用进行编辑测试,结果表明该系统设计方法可行。
In order to explore the design method of PLC ladder diagram(LAD)editor system,we start with the overall requirements of LAD editor system,analyze the shortcomings of the traditional LAD network,and use a high-degree-of-freedom network topology to describe LAD network. According to the network topology,a distributed storage scheme is proposed to implement the storage of connec?tion relationships between LAD primitives. The object-oriented software method based on the QT graphics framework is used to realize the functions of creating ladder diagram standard primitives,establishing connection relationships and deleting primitives. After com?pleting the design of the ladder diagram editing system,we tested the management of graphic elements and various instructions. No problems were found during the process. The results shows that the method of designing the ladder diagram editing system proposed in this paper is feasible.
