Abstract:

In the fields of aviation,aerospace,and industrial control,in order to improve system reliability and fault tolerance,redundant design is necessary for key signals,dual redundant signal being an often used redundancy strategy.This paper introduces a dual redundant processing technology,and at the same time in order to reduce the cost of system development,the design uses a software fault injection technology to authenticate and verify the processing technology.The results show that the technique is effective and feasible.

Key words: fault tolerance;dual redundant;fault injection
