串行接口设备接入Internet的解决方案

Proposal of Serial Communication Facility Connected to Internet

阐述了嵌入式Internet的硬、软件设计和实现过程。首先以单片机和以太网控制器RTL8019AS为核心搭建硬件平台;其次介绍了TCP/IP协议在嵌入式领域的简化、实现及应用;最后讨论了系统的功能模块划分。实现了串行标准协议与TCP/IP协议间的透明转接,达到了工业上的远程监控目的。

Design and implementation of hardware and software of embedded Internet are expatiated explicitly. First, a hardware platform is established with single chip computer and RTL8019AS as its core. Second, simplification, implementation and application of TCP/IP stack in embedded field are introduced. Finally, partition of system modules is well explained. The transition of serial communication protocol and TCP/IP protocol has been implemented, which achieves the intention of remote control.
