农业专家系统通用开发平台的设计

Design about the common developing platform agricultural expert system

针对农业专家系统的设计,笔者采用VisualC++语言工具,通过面向对象的设计方法,用ADO数据库连接技术连接Access或者SQLServer后台数据库建立专家知识库,通过建立文档设计动态对象单元,用ADO连接技术将对象单元与知识库中的数据进行特定连接,采用VBScript脚本语句实现对象与对象的逻辑关系,即实现专家推导的推理功能,从而能够自动实现农业专家系统设计与开发的基本思想,为快速开发适合广泛的农业专家系统的创建与实现提供了一个新的操作平台,从而提高开发的工作效率。

According to the design for agricultural expert system,based on Visual C++language tool and target-oriented design method,connecting ADO database technology with Access or SQL Server,the author set up expert's knowledge base.Through setting up target unit of file design,and connecting dynamic target unit with data of knowlˉedge base and adopting VBScript script sentence to realize the logic relation between the target and marriage partner,namely,realizing the reasoning function that the expert derives,this paper realize the basic thought that the agricultural expert system designs and develops automatically,and have offered a new operating platform for the establishment and realization of the extensive agricultural expert system.Thus we can improve the working efficiency.
