卫星接收故障诊断专家系统的研究

文章分析了卫星接收系统的故障机理,研究了基于故障树的专家系统推理机的实现,提出了一种卫星接收故障诊断专家系统的设计思想及实现方法。推理过程以正向推理技术为主,应用二叉搜索树建立故障树,采用产生式表示法表示事实知识和规则知识,应用数据库作为知识库,构造了卫星接收故障诊断专家系统,用于对实时卫星接收过程的故障判断,指导操作员排疑解难。

Research on Fault Diagnosis Expert System of Satellite Receiver

Analyze the fault mechanism of satellite receiving system,investigate the implement of expert system inference engine based on the fault tree,then propose an idea to design and realize the fault diagnosis expert system of Satellite Receiver.The item focus on the forward reasoning,building fault tree in application with binary search tree,while the fact knowledge and the rule knowledge are denoted by producing representation,applying database as a knowledge base,and build a fault diagnosis expert system of Satellite Receiver for the Real-time fault diagnosis,guiding operators master problem-solving skills.
