基于W5200的双冗余以太网通信系统应用研究

摘要

[Objectives]At present, the power management systems of ships require highly reliable Ethernet,and Ethernet communication cannot be interrupted when the system encounters a fault. [Methods]This paper introduces the working principle of the dual-redundant Ethernet system,and the processor ARM and the Ethernet control chip W5200 are used for the dual redundant Ethernet communication system.[Results]When the network fails or the line is damaged,the dual redundant Ethernet communication system can automatically reconnect so as to ensure that the communication system is healthy,safe and continuous.[Conclusions]The redundant communication system is verified by ship prototype with high application and promotion value.%[目的]目前舰船能量管理系统对以太网通信的可靠性要求非常高,不允许故障时通信被中断.[方法]研究双冗余以太网通信系统的工作机理,利用ARM处理器和以太网控制芯片W5200搭建双冗余以太网通信系统,[结果]实现了在一路网络发生故障或线路受损时,可以自动切换重连,能确保通信系统健康、安全、持续运行.[结论]该冗余通信系统在某舰船样机中得到了验证,具有较高的应用与推广价值.
