While most of current research focuses on design and simulation of fault diagnosis algorithm, this design puts fault diagnosis as a system which integrates with other vessel systems. The features of designed diagnosis system are as follows. It is based on network platform, the basic data which is for neural network diagnosis comes from historical data and real-time data of marine network platform; The diagnosis system in real-time displays training procedure in the intuitive form, including dynamic curve of network output and grid display of weight and threshold. The diagnosis system gives a clear diagnostic result in the form of text. Using this system, 2下载后可任意编辑it can fully take advantages of network platform and effectively diagnose and forecast main propulsion plant failu...
