Abstract

Because of the particularity of the diagnosis task, the software system is required to correctly identify all possible fault types, especially to prevent misdiagnosis or missing diagnosis of abnormal faults. It is also required to evaluate the severity of the fault and predict the deterioration trend to assist users to make timely and correct responses. After the fault diagnosis task is completed, a decision is made as to whether maintenance is required. If maintenance is required, comprehensive analysis and evaluation of feasible maintenance technical schemes are carried out to select the most satisfactory maintenance schemes.
