【摘要】 随着微电子技术的发展，嵌入式系统在家庭和工业的各个领域得到了广泛的应用，在各种信息电器、移动计算设备、网络设备以及工控领域中都出现了嵌入式系统的身影，其数量已经远远超过了各种通用计算机。另一方面Internet已成为现代社会最为重要的基础信息设施之一，通过Internet可方便快捷的获取各种信息，而嵌入式系统一般是独立于Internet网以外的。随着技术的发展和实际的需要，Internet网络也不能局限于信息管理层面，嵌入式系统中也有必要实现远程控制、参数的网络测量，信息共享，从而实现信息家电、测控设备的网络化，因此将嵌入式系统接入Internet的问题显得越来越重要。目前以太网是应用最为广泛的网络，而TCP／IP协议是其中的标准化协议，将这两种技术应用于嵌入式系统即是嵌入式以太网技术，其中最为关键的是嵌入式TCP／IP协议的实现。本文对嵌入式以太网技术的实现、应用作了探讨。 本文介绍了嵌入式TCP／IP协议的特点，并结合嵌入式应用的特点对嵌入式TCP／IP协议的进行了全面地分析，提出了总体设计思想、一些设计的考虑。详细介绍了实现嵌入式TCP／IP协议的硬件系统设计、各组成部分的功能以及网络控制芯片的数据接收发送机理。本文对所用到的TCP／IP协议族的基本协议如ARP、IP、ICMP、TCP、UDP等都做了详细分析，并且根据嵌入式领域的特殊要求，对传统算法做了一些改动以提高这些协议的实时性，文中还给出了它们的功能模型与函数关系图或流程图。最后，对嵌入式以太网技术在智能交通控制系统中的应用进行了探讨。更多还原

【Abstract】 With the development of the microelectronics technology, embedded system has been adopted and widely used in a wide range of fields concerning the family life as well as the industrial production, such as household appliances, mobile communication, network instruments, and industrial control. Now the number of embedded system has surpassed that of all kinds of general computers. On the other hand, Internet has become one of the most important and necessary communication establishments. But embedded system is generally independent of the Internet. With the development of technology and the increase of practical demands, Internet should not be confined on information management level. And it is necessary for embedded system to realize remote measure, control and share information. So how to connect the embedded system to Internet has become a more and more important problem. Applying Ethernet and TCP/IP technology to embedded system is called "embedded Ethernet technology". This thesis discusses and explores the realization and application of embedded Ethernet technology.This thesis introduces the features of embedded TCP/IP protocol, then analyzes embedded TCP/IP protocol from embedded field, and puts forward the overall design model and some details. This paper does some deep research on some basic TCP/IP protocol, such as ARP, ICMP, IP, UDP, TCP in order to improve the real-time character. This thesis also proposes some new algorithms to modify traditional ones. In the final part of this thesis, the author studies the application of embedded Ethernet technology in intelligent communication control system.更多还原
