Summary:The invention discloses a boiler water supply system fault identification method for the problem of boiler water supply system fault identification, and the method comprises the steps: determining a fault identification frame of a boiler water supply system, and outputting the basic probability assignment of a fault; calculating the similarity, the certainty degree and the credibility of the basic probability assignment of each sensor; calculating the weight of the basic probability assignment of each sensor; calculating weighted basic probability assignment of the fault; and performing assignment fusion on the weighted basic probability by using a D-S fusion rule, and outputting a final fusion result. And judging the final fusion result according to a decision rule, and outputting a diagnosis result. According to the method, known information can be fully utilized, the effectiveness of fault basic probability assignment is comprehensively represented, and an accurate fault recognition result is obtained. 本发明
