【摘要】 为使电网图成为电力系统应用软件的通用 I/O接口 ,同时解决电网图的自动绘制问题 ,构建了一种基于面向对象知识库的电网图智能 CAD系统。通过把专业图形的基本元素处理成知识对象 ,再将关系数据库作为实事型知识的重要载体、绘图规则编成过程写入知识对象 ,以及将绘图方法和经验转化成推理策略 ,并选用产生式专家系统的工作模式 ,使系统成功获得自动绘图、识别图面细节以及维护知识库绘图知识等多项智能行为更多还原

【Abstract】 This paper describes an Object-Oriented Knowledge Based (OOKB) intelligent CAD system for Power System Graph, which not only creates an interface for the power system integrated software, but also solves the problem of automatic drawing of Power System Graph. In this system, elements of the graph are transformed into knowledge objects, which encapsulate the knowledge from the database and the rules of drawing. A Production System is also introduced, whose inference strategies are obtained from expert experience and drawing techniques. Therefore, the system achieves the intelligent behaviors including automatic drawing, graphic feature recognizing and knowledge maintaining.更多还原
