摘　　要：船用保护装置中的通讯方式通常采用modbus/tcp通信,经常出现1对多、多对多的通信场景。本文以STM32103ZET6和网络芯片DM9000c为核心,设计了一种船用保护装置嵌入式双以太网接口。通过对DM9000c进行初始化、数据包封包和解析,并通过FSMC对DM9000c进行读和写,DM9000c则负责数据的发送和接收。文中详细描述了硬件电路板设计思路和软件设计流程。该设计能进行信息的高速传输,实现以太网口拓展功能。The communication method in marine protection devices usually uses Modbus/TCP communication,1-to-many and many to many communication scenarios happen all the time.This article designs an embedded dual Ethernet interface for marine protection devices based on STM32103ZET6 and network chip dm9000c.By initializing,encapsulating,and parsing dm9000c,and reading and writing dm9000c through FSMC,dm9000c is responsible for sending and receiving data.The article provides a detailed description of the hardware circuit board design concept and software design process.This design can achieve high-speed information transmission and expand the ethernet port function.
