S tudy on sensors fault tolerance in detecting system of tilting train

It is vital for the safety of tilting train to tilt correctly,and one precondition is to detect the uncompensated accelera-tion accurately and reliably.Setting multi-parallel-sensor may improve the reliability of detecting it.The optimal number of units is computed under the set reliability.The sensors fault-decision-making logic and threshold parameters are determined while their fault process and patterns are discussed.The real data simulation shows that multi-module hardware redundancy and the relevant fault-decision-making logic can efficiently tolerate the sensors fault,the project and the algorithm presented in this paper are also practical.
