摘　　要：目前在模拟电路故障诊断及测试过程中存在两个问题:测试信号的连续性及容差特性造成的测试信号数量巨大,故障知识表示复杂,测试程序(Test Program,简称TP)的编写多用基于决策知识的人工生成方法;通过对IEEE1232标准的体系结构和诊断推理机要求的分析,论文对IEEEE1232模型体系进行扩充,提出一种包含特征提取技术和多种AI诊断方法的诊断知识库生成协议,设计并实现了符合1232标准知识库的TPS自动生成测试系统;提高了诊断知识的移植性,实现了TPS的自动生成;仿真结果证明了该方案的可行性。Currently there are two problems in analog circuit fault diagnosis and testing process： test signal continuity and tolerance characteristics of the test signal caused a huge number of test signals, the representation of fault knowledge ~s complex, compile test pro- gram mostly based on the decision knowledge of artificially generated. To analysis the IEEE1232 standard architectures and the require- ments of inference engine, this article expanse the IEEEE1232 model system for expansion, propose a diagnose knowledgebase generating protocol which contains feature extraction technology and various AI diagnostic methods, comply with 1232 standards diagnose knowledge- base design and implement the automatic analog TPS generating system. Improve the portability of diagnostic knowledge, achieve the TPS automatically generated. The simulation results demonstrate the feasibility of the scheme.
