Fault Diagnosis Method for Marine Engine System Combined with Multiple Clusters Using Label Propagation

Abstract

Fault diagnosis for marine engine system can be achieved by cluster process. We propose a multiple clusters method using label propagation model repeatedly to cluster for fault samples. Due to randomness in label propagation, some classes which are not easy to be found in single cluster can be found. To verify the performance of this method, the samples from self-manufactured marine engine room simulator are used in fault diagnosis simulation experiment. Both fault analysis results and fault diagnosis results are completely correct, and fault pattern which is not in fault history data can be recognized.
