【摘要】 近年来,随着计算机软硬件技术的迅速发展,计算机的应用已逐渐深入各个领域。计算机网络的发展使得人们可以远程控制各种联网设备,在办公室就可以监控远端的设备运行状态,并且对设备进行操作。 基于WEB方式和SNMP方式是目前两种流行的网络管理方式。 SNMP协议是当前发展较为迅速的网络管理协议,因为其突出的简单性,良好的可扩展性,得到了业界许多厂商的支持,成为事实上的网络管理标准。 一些通信网络设备,如:光纤收发器,以太网集线器,接口转换器等,由于成本,技术或实际管理方面的问题,本身不带网络管理协议及相应管理软件。因此需要设计一个合适的嵌入式网管系统,便于设备的管理及功能的扩展。 本文首先在前两章介绍了嵌入式系统的概况及SNMP协议。 在第3章介绍了基于RABBIT 2000微控制器,不带操作系统的嵌入式WEB服务器的设计,用户通过WEB浏览器就可以管理设备。 在第4,5,6章详细介绍了基于ARM7TDMI处理器,使用UCLINUX操作系统的嵌入式SNMP代理的软硬件设计,包括UCLINUX开发环境及开发过程,硬件电路的设计与调试,软件的设计与移植。 本文的系统设计不需要多少成本,其中的SNMP代理使用开放源码的UCD_SNMP开发包:操作系统UCLINUX也是开发源码和免费的,而性能与商用的嵌入式操作系统相差无几。因此非常适合于对成本敏感的系统设计。更多还原

【Abstract】 In these years, along with the rapid development of computer technology, the application of computer has become more and more wide in various fields. Now, one can control remotely any devices connected to network by the network technology, monitor the operating devices, and running devices with a computer in the office.Web server and SNMP are the two most popular network management methods.SNMP is growing fast because of its outstanding simplicity and good expansibility. It gets much support from many manufactures and becomes actually the standard for network management protocol.In first two chapters, the thesis firstly introduces embedded system and SNMP. In chapter 3, an embedded web server based on RABBIT 2000 microprocessor without OS is described. Users can control device through an internet explorer.In chapter 4, 5, and 6, detail technical specifications of the design and implement for a SNMP agent are discussed. UCLINX OS and ARM7TDMI microprocessor are applied in the corresponding system. The developing environment, the developing procedure, the design and debugging of hardware, and the design and parts of software are also presented.The cost of the system presented is quite low because we use the free UCD_SNMP package to develop SNMP agent and use the free UCLINUX as the embedded OS, which has a good performance like commercial ones. The above design procedure is suitable for those applications sensitive to cost.更多还原
