利用CAN总线的在线故障诊断专家系统的实现

为了能更快速、准确的诊断出武器系统的故障,将CAN总线应用到某武器系统.构建一种基于CAN总线的在线故障诊断专家系统.此系统能通过CAN总线直接获取武器系统的自检信息和在线检测信息,并根据相应信息,利用故障诊断专家系统,对知识库进行搜索匹配,诊断推理,得出故障诊断结论,并给出相应的排除故障的措施和维修意见.实践表明该系统提高了某武器系统的故障诊断效率和正确率.

The On-line Fault Diagnosis Expert System Based on CAN Bus

In order to more rapidly and accurately diagnose the fault of a weapon system,the CAN bus was applied to a weapon system. The on-line fault diagnosis expert system was built based on CAN bus. The system can directly access self-test information and on-line test information of weapons and in accordance with the appropriate information search the knowledge base of fault diagnosis expert system for matching, diagnostic reasoning and drawing conclusions of fault diagnosis. The corresponding troubleshooting and maintenance advice are provided. The practice indicates that the system improves the efficiency and accuracy of fault diagnosis of a weapon system.
