甘蔗收获机械知识发现系统是甘蔗收获机械智能设计的核心部分。针对甘蔗收获机械的特点,提出了基于双库(基础数据库和知识库)协同机制的甘蔗收获机械知识发现系统的开发;阐述了该系统的总体结构;介绍了基于SQLServer的数据准备模块、基于多种算法的数据挖掘模块、基于信息扩散理论的评价模块以及基于双库的协同模块。通过对砍蔗机构的实例运行检验,证明系统可以有效地发现知识,为甘蔗收获机械智能设计提供了知识支持。
Sugarcane harvester knowledge discovery system is a key technology in Intelligent Design System for Sugarcane Harvester. According to the knowledge feature of sugarcane harvester, a sugarcane harvester knowledge discovery system based on double-base(database and knowledge base) cooperating mechanism is developed. The overall structure,the data preparation module based on SQL Server,the data mining module based on the algorithms,the evaluation module based on information diffuse theory, and the cooperating module based on double-base are discussed.It is proved that the knowledge is effectively discovered through the case in Cut part, and gives knowledge support to the intelligent design of sugarcane harvester.
