摘　　要：针对机载电子设备TCAS系统故障诊断处于板级电路局限的问题,提出以TCAS处理器为诊断对象的TCAS系统元件级故障诊断专家系统。对TCAS元件级故障诊断专家系统知识库和推理机的建立做了较深入研究,提出了将案例推理子系统和故障树推理子系统相结合的专家系统设计方案。该方案能够根据TCAS系统的故障现象快速准确地诊断出故障原因并给出相应排除措施,可以达到对机载电子设备TCAS系统进行深度测试与诊断的目的。TCAS component level fault diagnosis expert system for TCAS processor was put forward in view of airborne electronic equipment TCAS system limitations, such as fault diagnosis in PCB-level circuit element level. Intensive study was done for the establishment of a knowledge base and reasoning machine for TCAS element level fault diagnosis expert system; and expert system design scheme of combining the subsystems of case-based reasoning and fault tree reasoning was put forward. The scheme could rapidly and accurately diagnose the cause of the problem according to the phenomenon of TCAS system and provided the corresponding troubleshooting measures. The deep test for airborne electronic equipment TCAS and diagnosis effect could be achieved.
