目前为了实现远程数据采集、远程监控等功能，网络化已成为新一代嵌入式系统发展的重要趋势。所以本文使用8 位单片机与RTL8019 网络控制器芯片组成一个能够连接两个网络的网关，从而实现了RS232/485 等轻型网络中的嵌入式系统与以太网数据终端的互联。关键词：嵌入式系统；以太网；RS232/485 通信；The design and implementation of the conventer of uart to Ethernet YUAN， Weiqi MO， Yunpeng （Computer Vision Group in Shenyang University of Technology ） Abstract: To realize long-distance data collection and control and so on,the network has become a trend of the development of new generation embedded system. So the approach and strategy of the conventer of uart to ethernet，which make a gateway with RTL8019 netcard chip and 8-bit MCU，is introduced in this paper.Key words: Embemded System; Ethernet; Uart;
