%X In order to reduce uncertain problem of circuit fault diagnosis,an information fusion method,which is for photovoltaic radar electronic equipment fault diagnosis based on Dempster_Shafer (DS) evidential theory and fuzzy logical theory,is presented.According to the measurement results of the temperature and the voltage of circuit component,the belief function assignment of two sensors to circuit component,and the fusion belief function assignment was obtained by using DS rule and fuzzy method respectively,then fault component was found.By comparing the diagnosis results based on separate original data and fused date respectively,the latter was proved more accurate;By comparing fuzzy fusion method with DS algorithm,the DS fusion algorithm is more accurate in the circuit fault recognition.
