The Research Of Intelligent Ship Engine Room Monitoring System Based On CAN Bus

In recent years, with the development of computer, communication, networking andcontrol technology, fieldbus technology is increasingly being used in ship automation andcontrol systems. Ship engine room monitoring system is experiencing a technical change.The starting point of this study is based on the domestic and foreign ship engine roommonitoring system to explore the latest trends of that. This paper mainly researches theintelligent engine room monitoring system which is based on CAN field bus.This paper, firstly analyzed the development trends and current status of ship engineroom monitoring system, and introduced the application of field bus technology in theengine room automation. Then it present several typical field bus technologies, detailedabout the concept of CAN and analyed CAN bus communication protocol.According to the functional requirements of ship engine room monitoring system, thearticle proposed a monitoring system based on CAN bus and described its characteristics.After that, the CAN node was designed, which used C8051F040MCU as themicroprocessor, and then detailed the design of hardware and software modules of the CANnode, especially the CAN communication program.The function of intelligent data analysis demonstrates the intelligent development ofthe ship engine room monitoring system. Aim at fault diagnosis of the complex marinediesel engine system, the paper proposes an improved particle swarm optimizationalgorithm, combined to fuzzy neural network fault diagnosis model to optimize theparameters of its training. After simulating the ship diesel combustion system through theintelligent fault diagnosis, and comparing with the fuzzy neural network based on traditionalBP algorithm, we get a more accurate diagnosis result, improve the generalization ability,and overcome the the lack of BP algorithm, which shows the effectiveness and feasibility.At the last of this paper, the data-based multi-form monitoring software was designedby using Visual C++, with details of the rights management, real-time monitoring, databasemanagement module. An intelligent data processing methods based on particle swarmoptimization (PSO) algorithm was creatively integrated in the PC monitoring systemsoftware, which achieves online fault diagnosis for marine diesel engine combustion system.The intelligent ship engine room monitoring system based on CAN bus has powerfulfunctions, high reliability, which will help raise the level of ship automation, reduce the difficulty and cost effectively of system design and greatly reduce the labor intensity of thecrew, has a good potential applications and markets prospects.
