摘　　要：介绍一种以潜艇指控系统电路板作为被测对象故障诊断技术,对指控系统电路的测试由布尔差分法产生可检测和可区分故障的测试向量,采用模拟开关菊花链连接方式实现多通道多类型测试激励信号的生成和响应采集。运用该技术设计的自动测试仪可对某型潜艇指控系统各种类型电路板进行测试和故障诊断。A kind of fault-detection technology is presented for printed circuit board （PCB） of some kind submarine＇s C^3I. The testing vectors for digital circuit＇s measurable and distinguishable faults is produced from Boolean difference method. Daisy-chained connection of serial controlled single-pole-single-throw switches is used to realize multi-channel, various kind of testing vector and the collection of the response. Automatic testing instrument for PCB based on it can be used for the function detection and fault diagnose for each kind of PCB of the submarine＇s C^3I.
