| 摘 要： | 鉴于自动测试系统研究中缺乏确认其故障冗余属性的手段,提出一种基于对比策略的故障注入系统。系统采用硬件注入和软件仿真相结合的方法实现,故障注入由专门研制的电压信号发生器、电流信号发生器、后驱动电路完成,自动测试系统的正常运行通过软件仿真完成。实验结果表明利用该系统能发现自动测试系统的软件缺陷,并能对其故障冗余属性进行确认。

| Abstract: | Considering the deficiency of the means for confirming the attribution of fault redundancy in the research of Automatic Testing System(ATS),this thesis presents a fault injection system on the basis of comparing method.The system adopts the method of a connection hardware injection with software simulation. The fault injection consists of voltage signal generator,current signal generator and rear drive circuit which are specially developed,and the ATS can work regularly by means of software simulation.The experimental result indicates that the fault injection system can find the deficiency of the automatic testing software,and identify the attribution of fault redundancy. |
