摘要

The electronic component plays an important role in the safety and operation of the maglev train. In order to reduce the uncertainties of problem with the electronic components fault diagnosis, a modified D-S evidence theory based on information fusion, which can deal with the evidence conflict well, is presented in the paper. According to the measurement results of current and voltage of circuit components, combined with the modified D-S evidence theory, the fault component will be found. Experimental results certify that the method can carry out the fault diagnosis effectively.
