| 摘 要： | 针对联合收获机知识缺乏系统化组织与分类、难以在设计时高效获取并应用的问题,应用装备谱系及谱系拓扑图形式对联合收获机知识进行层次化组织;按照联合收获机智能化设计实际应用需求,对知识库系统功能模块进行架构分析;分析了农机装备设计知识的表现形式,综合利用产生式规则和框架表示的混合表示方法对设计过程进行分析和表达,建立了设计体系。以Visual Studio 2015平台为开发工具,在.Net环境下,应用ADO.Net技术、CATIA二次开发技术及SQL Server数据库,将联合收获机设计知识、参数化模型等数字化资源融和,进行组织管理,构建了联合收获机知识库系统。通过人机交互的方式,将知识表达形成的设计体系系统化,应用模糊查询方法、推理机和ADO.Net技术实现系统中知识的查询、推理及编辑功能,并将知识推送的结果传递给关联的参数化模型驱动,在不同需求下快速构建模型,实现了知识的高效获取与应用,提高了设计效率,为联合收获机零部件设计提供了一种通用方法。系统测试表明,该系统具有可行性和有效性,适用于联合收获机系列产品的开发。

| Abstract: | According to the lack of systematic organization and classification of combine harvester knowledge, it was difficult to obtain and apply it efficiently in design. The concept of equipment pedigree and pedigree topology map was used to manage the knowledge and construct the knowledge base system of combine harvester under the traction of the actual application demand of intelligent design of combine harvester. Combined with the characteristics and forms of agricultural machinery design knowledge, the design process was analyzed and expressed by using the hybrid representation method of production rules and frame representation, and the design system was established. It used Visual Studio 2015 as the development tool, under the environment of . Net, using ADO.Net technology, CATIA secondary development technology and SQL Server database, the combine harvester design knowledge, parametric models and other resources were integrated and organized to build the combine harvester knowledge base system. By means of human-computer interaction, the design system was systematized, and the functions of knowledge query, reasoning and editing were realized by using fuzzy query, inference engine and ADO.Net. In addition, system transferred the pushed knowledge to the associated parametric models. The parameters of the related parametric models were adjusted, the models under different needs were quickly built, the design time was cut down and the design efficiency was improved. The knowledge base system could save the time of knowledge acquisition and analysis through case analysis, the system was used to query, reason, push and transfer the knowledge to the models for driving. This method can realize the efficient application of knowledge, enhance the inheritance and reuse of knowledge, improve the design efficiency, and provide a general method for the design of combine harvester parts. It was applicable to the requirements of the development of combine harvester series products, and establish the basis for the construction of a special intelligent design platform for combine harvester. |
