The fault diagnosis of marine engine cooling system based on artificial neural network (ANN)

This paper makes a further research on fault diagnosis of marine engine cooling system based on artificial neural network (ANN). Firstly, it introduces the basic principle of ANN. The following section goes to describe the back propagation (BP) algorithm of neural network, basic structure of BP network and learning algorithm in detail. Finally, BP algorithm is used to detect and diagnose faults of marine engine cooling system. The research results are satisfactory and indicate that the network is simple in structure and good in speed of learning and adaptability.
