Abstract: ( ) ,
To manage and monitor BAS equipment effectively and improve the relia,bility researched a re,liability
method of BAS based on the theory of co,nnection number of pair,analysis and FTA Firstly every kind of factors which唱
could make the building equipment fault was analysis deeply ,ted a fault tree and confirmed the reasons of sys
tem fault in every bination way by the fault tree model Secondly established a BAS reliability mode,l
combined with the conception of intermediate probability and the theory of connection
