Computer Aided Design of Relay Control Circuit System

为了解决继电控制线路系统传统设计方法的弊端 ,提出计算机辅助设计方法 .该方法分析了电气原理图的特点 ,采用网络拓扑方法描述电气原理图的连接关系 ,并且提出电气元件逻辑关系的描述方法、元件自动匹配方法和电气设备间电缆最短长度的计算方法 .在此基础上 ,实现了设备端子排和电缆表的自动生成 ,并对设计结果进行了优化 .实践证明 ,基于上述方法开发的CAD软件能够自动完成大部分设计工作 ,提高了设计效率 。

The characteristics of secondly circuit diagram are analyzed and the network topological coding system is used to describe the connected relationships in the diagram. The paper also puts forward the way of identifying the logical relation of electrical apparatus, automatic matching d of electrical apparatus and the method to calculate the shortest cable length between electrical devices. By using the methods, the electrical device terminal array and cable list can be generated automatically,meanwhile,the design result is optimized. The developed CAD software can automatically accomplish most work that was done manually before,it improves the design efficiency and optimizes the design result.
