基于专家系统的地空导弹发控设备故障诊断设计

Design of Launch System Fault Diagnosis Expert System for Ground-to-Air Missile

在对地空导弹发控设备故障分析的基础上,提出基于主站的故障信息集中处理方案(Customer/Server,即C/S)的地空导弹发控设备故障诊断专家系统总体框架和系统各功能的实现方法,并开发了系统的原型;该系统将基于产生式规则和案例和模型的诊断方法结合在一起,通过采用启发性知识和逻辑性知识相结合的混合推理方法实现推理;此系统主要有2个工作步骤:故障检索和故障可能性排序;该系统对故障信心获取比较全面,诊断可靠性高,且硬件成本低。

Following a discussion on fault of launch system, a customer/service architecture framework of fault diagnosis expert system, together with its implementation and prototype, was put forward. The system integrated rule--based reasoning and case--based reasoning, and it could reason with heuristic knowledge and logic knowledge inference engine. When this system functioned, it worked in these two steps： searching fault from fault database and ranking the fault to obtain a selection result.
