基于CAN总线的船舶网络通信可靠性研究

Research on reliability of ship network communication based on CAN bus

控制局域网(Control Area Network,CAN)是当前广泛应用于工业制造、设备控制、系统监测等领域的信号传输与控制网络,相比于RS-485具有通信实时性强,开发周期短,覆盖范围广等优势。基于CAN总线的船舶通信网络,承担着船舶控制、设备监测等重要功能,因此网络通信的可靠性对于船舶的安全行驶具有重要的意义。为此,本文提出一种备用通信路径计算方法,在单链路故障的应用场景下,能够有效提升故障恢复的效率,从而提高网络通信的可靠性。

Control Area Network(Control Area Network) is widely used in industrial manufacturing, equipment control, system monitoring and other fields of signal transmission and control network, compared to RS-485 with real-time communication, short development cycle, wide coverage and other advantages The Based on CAN bus, the ship communication network is responsible for the important functions of ship control and equipment monitoring. Therefore, the reliability of network communication is of great significance to the safe driving of the ship. In this paper, an alternative communication path calculation method is proposed, which can effectively improve the efficiency of fault recovery in the application scenario of single link fault, so as to improve the reliability of network communication.
