Outline of Final Research Achievements

Generally, maintenance of the fishing boats can not completely carry out as compared to the large ship. The objective of this research is to construct of novel condition monitoring and diagosis system for fishing boat engine and neighborring machinery. Especially, we propose that the novel condition monitoring and diagnosis method on the compound faults occure in fishing boat that it is hard to detect.This method is based on a parabolic sound reflector type microphone and separation signal processing technique about composed sound generated by the monitored facilities. The important time series data generated by the compound faults occure in fishing boat can be extracted using the proporsal method.
