基于专家系统的异构图形数据格式转换方法研究

现在许多行业用到绘图软件，如建筑、机械、电气等，为了提高工作效率，常常需要将两种图形进行相互转换，如地理信息图与AutoCAD图形的相互转换，但是多种绘图软件之间并不为对方提供转换的接口。本文建立了一种基于专家系统的异构图形数据格式转换模型，通过图形转换综合数据库记录整个转换周期的实时状态；分析构建了图形转换知识库，保证知识库的全面性和正确性成为关键；基于正向推理策略设计图形转换推理机制。本文的创新点为将专家系统引入到异构图形转换中。解决了不同的图形数据格式之间的转换，并以油田中的双狐图形与AutoCAD图形为例，完成异构图形的转换。

Research on Heterogeneous Graphics Data Format Convertion Method Based on Expert System

Now many industry use of the drawing software,such as the construction,machinery,electricity.In order to improve work efficiency,we need convert two kinds of graphics,for instance the interconversion between geographic information figure and AutoCAD graph,but many kinds of drawing software did not provide conversion interface for each other.This paper established a kind of model of heterogeneous graphics data format conversion based on expert system,through the graphics conversion comprehensive database records the real-time state in the whole switching cycle,analysises and constructs the graphics conversion knowledge base,guarantee the comprehensiveness and correctness of knowledge base become a key,design graphics conversion reasoning mechanism based on forward reasoning strategy.The innovation point of this paper is that expert system are introduced in heterogeneous graphics conversion.Solved the convertion between different kinds of graphics data format,and take DoubleFox figure and AutoCAD graph in oil field for example,complete the transformation of different kinds of graphics.
