摘要
Abstract
The design and implementation of a universal safety computer based on switch fabric is presented.The architecture of the safety computing platform based on switch fabric is presented firstly.Then advantages of the architecture are analyzed,the reliabilities of 2-out-of-2(2oo2)×2 and 2-out-of-3(2oo3)safety computer are compared,the safety of 2-out-of-2(2oo2)×2 system is analyzed based on the Markov model,with the key factors which influence the system safety being pointed out.At last,the design consideration of synchro-nization&compare/vote,fail-over operation and safe communication are described in detail.关键词
