本文采用目前廣泛應用的工業以太網為通訊方式，提出以ARM9 開發板和 MIZI Linux
嵌入式操作系統為平臺的通信設計方案。在掌握ARM9 和 MIZI Linux 特點的基礎上，構建MIZI Linux 嵌入式操作系統下應用程序的軟硬件開發平臺。本方案采用DM9000 芯片來控制以太網，在實現通訊模塊調用的基礎上，進行Linux 下的Socket 網絡通信編程，實現智能終端的以太網通信功能。
關鍵詞：智能終端；以太網；MIZI Linux 嵌入式操作系統
Abstract: The design scheme based on ARM9 development board and MIZI Linux embedded
operation system was given according to the character of intelligent terminals. The software andhardware development platform of MIZI Linux embedded operation system was built. The
terminal used the DM9000 chip to control Ethernet communication. After the communication
module was used successfully, socket network program was programmed in Linux. Then the
intelligent terminal’s Ethernet communication function was realized.
Keywords: intelligent terminal; Ethernet; MIZI Linux Embedded OS
