【摘要】 TCP/IP协议的广泛应用,尤其是Internet技术的发展和普及,嵌入式设备的上网已是必然趋势。由于家庭网络中的各个设备来自不同的厂家,各自采用不同的软硬件技术,使用不同的规范,而且可能对信息家电的概念理解不同,于是会导致兼容性问题。如何将连入网络的各大企业生产的信息家电设备融合在一起,实现网络传输的可靠性和实时性并对其进行有效管理则是目前家庭网络要解决的主要问题。一般是通过家庭网关来解决此问题,现有的家庭网关价格较贵,对不同厂家生产的信息家电设备兼容性不好,不利于信息家电设备的推广。在信息家电设备中嵌入网管代理软件,使得管理者能够通过网络远程控制、监测信息家电设备,构建和维护家庭网络,代行家庭网关的部分功能。对信息家庭网络设备进行管理已成了网络管理领域的一大新课题。本课题针对这一趋势,对信息家电家庭网络管理系统进行了较为深入的研究与探讨,利用现代嵌入式网络管理技术来管理智能家居中信息家电设备。通过与传统网络管理模型的对比,详细讨论了固化在资源有限、计算能力有限的信息家电设备中的网络管理代理及其实现技术。SNMP简单网络管理协议由于其简洁、易实现,在网络管理领域技术成熟,成为本课题的首选。本课题在对信息家电体系结构、家庭网关功能及结构、信息家电网络管理模型及其与传统网络管理模型的对比、SNMP协议及其在信息家电中的应用等主要理论进行研究后,提出并设计了SNMP信息家电网络管理代理器,并在此网管代理器基础上搭建了信息家电家庭网络管理系统平台,该管理平台以SX52单片机为基础,利用外围硬件电路扩展和虚拟外围及网络协议软件虚拟模块,分别采用B/S方式和C/S方式模拟实现了信息家电网络管理,除能完成传统的网络管理功能外,还实现了家庭网关的部分功能,让资源有限的信息家电设备具有稳定的网络性能,并能实时的对联入网内的信息家电设备进行管理和监控,为进一步研究家庭网关和信息家电内部结构以及它们之间的功能分配提供了研究试验平台,为信息家电走入千家万户提供可能。更多还原

【Abstract】 With TCP / IP protocol widely applied, especially the development and popularization of Internet technology, embedded devices connecting the Internet becomes an inevitable trend. As various equipments of family network are made in different manufacturers, using different hardware, software technologies and standards, and the understanding of concept of Information Appliance may be different, it will lead to compatibility problem.How to combine the products of information appliance made in various corporations, and achieve the reliability and real-time of network transmission, with its effective management are the main problems which home network has to solve currently. We make use of home gateway to solve this problem, but the actual home gateway is too expensive, its compatibility to various corporations which produce information appliance is not good, it’ s bad for the generalizing of information appliance. Embedding the network management software agents in the information appliance network, managers can control and monitor information appliance remotely through network, at the same time, they can construct and maintain the home network to substitute some functions of home gateway. Managing the home network devices has become a new topic in the field of network management.Aimed at this trend, this task makes a further study and discussion in the home network system of information appliance, and makes use of modern embedded network management technology to manage the intelligent home appliances. To comparing with the traditional network management model, it discusses the Network Management Agent and Technology in detail, which are cured in the limited resources and computing power of information appliances. SNMP, because of its briefness, easiness to achieve, maturity in the field of network management technology, becomes the main subject of choice. By making research in the major theories in the information appliance architecture, the function and architecture of home gateway, the information appliance network management model and its comparison with the traditional network management model, and the SNMP protocol and its application in information appliances and so on, the topic proposes and designs a SNMP network management Agents of information appliance, and constructs the family network management system platform of information appliance based on the Management Agent. The management platform is based on SCM SX52, using the extension of external hardware circuit and virtual periphery and virtual network protocol software module, and simulates and achieves information appliance network management by B/S and C/S mode respectively, it can complete the function of traditional network management, and carries out some functions of home gateway. It makes the limited resources of information appliance be a stable network performance, accesses to manage and monitor real-timely in the information appliance which is online. It provides an experimental platform for researching home gateway and inner architecture of information appliance with their function distributing. It enables information appliance step into ordinary families.更多还原
