| 摘 要： | 通过分析传统的故障字典法存在的问题,提出了一种完全不同于传统方法的新的故障字典法。该方法依据支路屏蔽的思想,通过逐一屏蔽电路的各支路,建立起能诊断软、硬两类故障的故障字典。详细阐述了该字典的自动建立方法和原理,并通过诊断例子,证明了该方法的有效性。

| Abstract: | A new fault dictionary method of analog circuits is presented in this paper, The method is based on an idea of branch screen.By screening each branch of a circuit, it establishes a fault dictionary which can be used to diagnose soft and hard fault. The principles and automatic establishment method of the new fault dictionary are discussed in detail. The diagnosis example in this paper verified that the method is effective. |
