Abstract

A data fusion method for circuit fault diagnosis based on D S evidential theory and fuzzy logical theory is presented.By measuring the temperature and voltage of circuit component,the belief function assignment of two sensors to circuit component is gotten,and the fusion belief function assignment is gotten by using D S rule,and fault component is found.By comparing the diagnosis results based on separate original data and fused data respectively,it is shown that the latter is more accurate than the former in the circuit fault recognition.
