某短波接收机模拟电路故障诊断系统

本文是在研制某短波接收机整机故障诊断系统的基础上完成的。根据文献［１］所提出的一种新的直流故障字典法编制了Ｆｏｒｔｒａｎ程序、建立了该机整机的故障字典、设计了自动测试系统、编制了整机的诊断流程、设计了用户界面，使得该系统的使用简单方便。最后给出了应用该系统对一般中小规模模拟电路单个硬故障进行诊断的方法步骤。实际运行表明，该系统对故障的诊断准确有效，并具有一定的通用性。

The Fault Diagnosis System of Analogne Circuits For Some Short-wave Receiver

This paper, based on the development of a fault diagnosis system for some shortwave receiver, describes how a program is developed in fortran language according to a new approach so as to set up a DC dictionary. The program makes it possible for all the circuits boards of some receiver to be equipped with DC dictionaries. A user interface is designed for the easy and convenient use of the diagnosis system. The paper also explains the procedures of diagnosing and resolving problems in the small and medium scale circuits.
