哈尔滨工业大学工学硕士学位论文 - PAGE II - - 信息化网络家电模拟控系统的设计 摘要 随着电子技术和网络技术的不断发展，嵌入式系统在家庭和工业的各个领域都得到广泛应用，各种信息家电、网络设备以及工业控制领域都出现嵌入式系统的身影，其数量己经远远超过各种通用计算机。但是目前大多数嵌入式设备仍处于孤立应用阶段，为实现多个嵌入式设备之间信息共享和交流，通常利用RS232、RS485和CAN等总线组网。但是这些网络的有效半径较短，并且孤立于Internet网络以外，如果能把嵌入式设备直接接入Internet上，就可以用方便、低廉的方式实现信息共享和远程测控。因此，研究和应用嵌入式Internet技术具有非常重要的意义。 TCP/IP协议是目前最稳定的网络协议之一，同时它也是Internet的基础。TCP/IP是一个庞大的协议族，本文主要分析了地址解析协议ARP、IP协议、用户数据报协议UDP、传输控制协议TCP、Internet控制报文协议ICMP和超文本传输协议HTTP。 本文探讨了在嵌入式系统中实现TCP/IP协议的可行性，并在此基础上设计了一个Web服务器，客户端可以通过Web浏览器检测家电当前的工作状态和相关参数，还可以对家电进行远程控制。 关键词　嵌入式；TCP/IP协议；以太网；Web服务器；远程控制 The Design and Realization of Embedded Appliance Controllers Based on Internet Abstract With the development of electronic techniques’ and computer network techniques，embedded system has been widely used at home and industry in various fields. Consequently，it is far more used in info household appliances，network equipments and industry-controlling fields than in computers. However，most embedded systems are still applied separately. Usually network can be organized by RS232、RS485、CAN and so on in order to achieve the informational share and communication among the different embedded equipments. .Unfortunately their valid radius is shorter and they go beyond the Internet. if the embedded equipments can be connected with Internet, that will be convenient for us to realize the informational share with less money and control from far away. Therefore is very important to research and apply the embedded Internet technique. TCP/IP Protocol which is the base Internet is one of the stable network protocol. The present researcher mainly analyses ARP、IP、UDP、TCP、ICMP and HTTP in this thesis. The researcher shows the feasibility of TCP/IP in embedded system. An embedded server can be designed based on the TCP/IP. First, using Embedded Web Server, clients can acquire the current working state and some parameters of household appliances, secondly can control household appliances remotely.
