摘要
电气原理图的自动设计是提高成套电器的产品设计效率的关键。本文提出一种知识推理和实例推理相结合的方法,通过知识推理进行系统的初步设计和功能划分,运用实例推理实现各个子系统原理图设计。基于XML国际标准,建立了一种通用的电气图描述语言XvgML。实现了一种基于拓扑图搜索的原理图分析算法,可以从设计图纸中自动抽取电路功能单元的实例,在专家协助下更新知识库和实例库。基于Web开放式体系结构建立了一种分布式协同框架,并在此基础之上实现了成套电器的分布式智能设计系统。
In this paper, a casebased reasoning approach combining with knowledgebased reasoning technique to build the Intelligent CAD system for electrical design of electrical equipments is presented. In order to represent the cases of electrical circuit drawings, an electrical drawing description language, called XvgML, is implemented to describe the structure, principle and function of electric circuits. It can represent all kinds of graphic cases in the design process. From the perspective of graph theory, the electric circuit could be taken as a topological graph. Therefore a casebased learning method using topological graph search for electrical drawings is proposed. Moreover, a cooperative software model has been built, which provides an ObjectWeb framework for Internetoriented design environment. Also, a sample is given to demonstrate the use of this framework for implementation of electrical equipment ICAD system.
