Abstract
In recent years, with the development of computer, communication, networking and control technology, fieldbus technology is increasingly being used in ship automation and control 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 room monitoring system to explore the latest trends of that. This paper mainly researches the intelligent engine room monitoring system which is based on CAN field bus.
This paper, firstly analyzed the development trends and current status of ship engine room monitoring system, and introduced the application of field bus technology in the engine room automation. Then it present several typical field bus technologies, detailed about the concept of CAN and analyed CAN bus communication protocol.
According to the functional requirements of ship engine room monitoring system, the article proposed a monitoring system based on CAN bus and described its characteristics. After that, the CAN node was designed, which used C8051F040 MCU as the microprocessor, and then detailed the design of hardware and software modules of the CAN node, especially the CAN communication program.
The function of intelligent data analysis demonstrates the intelligent development of the ship engine room monitoring system. Aim at fault diagnosis of the complex marine diesel engine system, the paper proposes an improved particle swarm optimization algorithm, combined to fuzzy neural network fault diagnosis model to optimize the parameters of its training. After simulating the ship diesel combustion system through the intelligent fault diagnosis, and comparing with the fuzzy neural network based on traditional BP 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 designed by using Visual C++, with details of the rights management, real-time monitoring, database management module. An intelligent data processing methods based on particle swarm optimization (PSO) algorithm was creatively integrated in the PC monitoring system software, which achieves online fault diagnosis for marine diesel engine combustion system.
The intelligent ship engine room monitoring system based on CAN bus has powerful functions, 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 the crew, has a good potential applications and markets prospects.
Key words: CAN bus; Monitoring system; PSO; Fault diagnosis; Visual C++
