基于W5200的双冗余以太网通信系统应用研究

Study of dual redundant Ethernet communication system centered on W5200 IC

摘要:
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。

Abstract:
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.
