摘要
建立基于数据库的保质设计制图综合知识库,并对该知识库中的基本表结构、制图综合知识库的建立与维护、推理机制的实现分别进行阐述。其特点在于对质量知识的有效管理,使制图综合知识的作用不仅仅局限于综合开始阶段针对不同目标进行综合处理方法的选择,而是在综合的各个阶段能够进行质量的自动引导与控制,同时在表结构设计中对保质设计中的质量功能配置进行考虑,能够实现自动推理机制,从而在整个制图综合过程中发挥质量控制的作用。
On the basis of analyzing present knowledge base of cartographic generalization, cartographic generalization knowledge base designed for quality control based on database is developed, basic structure of table, development and maintenance and realization of reasoning principles of which are expatiated. The most notable characteristic of the knowledge base is that quality knowledge is managed efficiently, which makes the effect of cartographic generalization knowledge not only localize in choosing simple generalization operation aiming at different objects at the beginning of generalization, but also automated induct and control the quality during each process of generalization, meanwhile the function configure on design for quality is considered in the design of table structure, which can implement automated reasoning principles, exert quality control effect in the whole process of cartographic generalization.
