Abstract:[Objectives] In order to adapt to the development of unmanned ships, strengthen the ship-shore integrated management of ship power equipment,reduce the workload of marine engineers, and realize on-condition maintenance of ship power equipment,this paper designs an intelligent diagnosis system of ship power equipment allowing for ship-shore integrated management.[Methods]According to the functions and features,the health status of components is evaluated with the single parameter threshold method and the radar chart,and the evaluation results are presented in the form of health scores. For components scored below 70 points, the system automatically enters the decision-making support interface,and the corresponding decision for a fault is provided for the engineer's reference. Taking the training ship "yukun" as the target ship, the intelligent diagnosis system of the actual ship power equipment is verified.[Results]The results of actual ship verification show that the intelligent diagnosis system of ship power equipment has high accuracy and operability,which realizes the transformation from "breakdown maintenance" to "on-condition maintenance". [Conclusions] The intelligent diagnosis system of ship power equipment helps improve the safety of ship operation and has certain practical value.
