在发动机的故障诊断领域 ,专家系统 ( ES)正得到越来越广泛的应用。本文首先讨论了 ES的模板化思想 ;接着重点研究一种面向对象的规则型 ES模板 ,包括面向对象的规则知识表示、启发性的改进 DFS推理机制及图形化的人机界面三个方面 ;最后运用该模板创建了一个MCD磨粒诊断 ES实例。应用表明 ,规则型 ES模板化不仅增强了 ES的知识表示与启发推理的能力 ,而且为 ES的快速构造与实现开辟了一条新的途径
In the field of engine fault diagnosis, expert system (ES) is getting more and more widely used. This paper first discusses the templating idea of ES. Then it focuses on an object-oriented regular ES template, including object-oriented rule knowledge representation, enlightening and improving DFS reasoning mechanism and graphical human-computer interface. Finally, Use this template to create a MCD abrasive particle diagnosis ES example. The application shows that the rule-based ES template not only enhances the ES’s knowledge representation and heuristic reasoning capabilities, but also opens up a new way for the rapid construction and implementation of ES
