摘　　要：针对鱼雷自导系统BIT(机内测试)设计故障诊断准确率低,可信度不高的问题,设计并实现了一种鱼雷自导系统测试性验证平台;通过对鱼雷自导系统数字机的各个组成部分注入故障(软、硬件故障共22个),分析BIT上传数据,对注入的故障进行检测和隔离,对比隔离出的故障和注入的故障是否一致,验证BIT设计是否有效;实验表明,平台能够对BIT设计进行验证,对缩短鱼雷研制周期,提高鱼雷故障诊断效率有重要作用。To construct a high accurate and believable BIT design for torpedo homing system, an experimental validation device is de- signed. In order to achieve the purpose faults （22 kinds of soft or hard faults） should be injected to the system, then detect and isolate faults based on the response. The BIT design is valid or not judging by whether the faults diagnosed are the same as injected. The experiment shows that the device designed is effective for the BIT validation of the torpedo homing system, which is important to decrease the develop- ment cycle of torpedo and useful to increase the efficiency of fault diagnosis for torpedo.
