基于数据库技术的机床设计知识库系统的开发

摘要

为了解决机床设计中存在的知识复杂、知识量巨大和管理困难的问题,基于数据库技术开发了机床设计知识库系统以帮助机床设计人员更好更快地完成机床的设计,成功实现了对机床设计知识的添加、查询、修改、删除和检查等功能.将系统结构设计成三层:基础数据库和接口层、功能层及应用层,详细进行了系统的功能模块设计,并分析了系统实现的需求分析与功能抽象、数据库设计、系统对图形对象的处理和知识管理等关键技术,最后给出了应用实例.%To solve the existing problems of knowledge complexity and management difficulty,a machine tool design knowledge base system was developed based on database technology to assist designers in completing the design of machine tools better and faster, which successfully accomplished the functions of knowledge addition,query,modification, deletion and inspection.Then system's structure was divided into three layers:database and interface layer,function layer and application layer,and system's function module design was carried out in detail,in addition key technologies were analyzed, such as the system demand analysis,function abstraction,database design,graphical objects processing and knowledge management technology etc.At last,an application example was represented.
