【摘要】 嵌入式系统在日常生活中得到越来越广泛的应用，随着技术的发展和实际应用的需要，在很多嵌入式系统应用中体现出跟因特网互连进行信息共享的必要性，但由于嵌入式系统本身资源的有限性，要实现复杂的网络协议栈使嵌入式宿主设备具备网络功能，目前还比较困难，特别在8位单片机上实现，有更多的困难需要考虑。 根据实际需要提出了一种采用8位单片机实现嵌入式Internet的实现方法，并研制了一套UPS／EPS远程网络监控系统。系统通过在传统UPS内嵌入一块网络板，提供一个UPS与以太网的接口从而使UPS具备网络监测功能，文章详细介绍了本套网络监控系统的设计思想及过程，内容包括网络板电路设计，精简的TCP／IP协议栈设计，网络板总体软件设计以及基于WINDOWS的网络监控软件及参数设置软件设计，网络板电路设计和嵌入式TCP／IP协议栈的实现是系统设计的关键，文章对这两部分做了重点阐述，嵌入式TCP／IP协议栈实现的协议包括：802.3以太网协议，ARP，IP，ICMP，UDP，TCP，同时，嵌入式TCP／IP协议栈与基于WINDOWS平台的网络监控软件通信的实现也是本系统实现的关键，文章对这一部分也作了详细说明。文章最后说明了网络监控系统的调试及测试结果。本套网络监控系统一次性通过了青岛创统科技有限公司的产品鉴定，现已批量生产，说明文章提出的嵌入式Internet实现方法可行而且具有广阔的应用前景。更多还原

【Abstract】 In recent years, embedded systems are widely used in daily life. With the development of technology and practical application demand, more and more embedded applications demonstrate that it’ s necessary to realize Internet connectivity between embedded system and Internet. But it’ s difficult to embed the complicated TCP/IP protocol stack into embedded system because of its limited resource, especially in 8bit systems.According to practical project demand, putting forward a method which enable 8bit embedded system connect to Internet. With this method, An embedded UPS/EPS remote network monitor system was designed. It is realized by embedding a network board into traditional UPS or EPS. The network board supplies UPS an Interface to Ethernet, this can make UPS or EPS connect to Internet. The paper describes how to design the system in detail, which includes network board hardware design, embedded TCP/IP protocol stack design, the whole software realization of network board and two WINDOWS platform software (network monitor software and parameter setup software). The network board hardware design and embedded TCP/IP realization is the core part of this system, the paper describes these two parts as focus, the realized embedded TCP/IP protocol stack includes 802.3 Ethernet protocol, IP, ICMP, ARP, UDP, TCP. At the same time the communication realization between embedded TCP/IP and network monitor software is critical too in the system, it is described in detail too. Finally the paper describes the debug and test result of the whole system. The system passed product appraisal one time by QingDao GOMA Co. Ltd. Now it has been widely produced. All these illustrated the method of embedded Internet is feasible and has good application foreground.更多还原
