2010 年湖南省研究生创新论坛信息与控制工程的新理论和新技术分论坛论文集 信 息 家  电 系 统服务定位器的设计  The System of Information Appliancethe design of service  locator   Wang Kun 刘 宏 教授 摘 要:随着计算机技术、网络通信技术及家电产业的飞速发展，信息技术正逐步向传统的家用电子 产业渗透，一种新型产业——信息家电产业正在迅速崛起。嵌入式技术的蓬勃兴起和广泛应用为信 息家电的发展指明了技术发展趋势，尤其是与互联网的结合，其作为信息和资源结点的功能越来越 明显。信息家电平台为我们提供一个更广阔的范畴，即要在分布式硬件、家用设备、移动设备以及 软件对象间达成协作。 本文在介绍信息家电系统工作流程的基础上，结合信息家电的面向对象性，提出了服务定位器的概 念。首先是对服务定位器所应具备的功能进行了描述，然后根据其功能需要设计了服务行为器的功 能组件模型，最后，在此以上基础上对服务定位器工作原理进一步加以说明。 关键词：信息家电系统，查找，发现，Service Locator，IAServiceID ABSTRACT:With the development of computer technology, network technology and electrical household appliance industry, the information technology has been gradually infiltrated into the traditional consumer electronics industry, and a new industry called Information Appliance is rapidly growing up. The emergence and widespread application of embedded technology has provided great technology for the development of Information Appliance, whose information and resource node function is obviously when it is combined with internet. The platform of Information Appliances provides us with a broad categories, in other words，it can create kind of cooperative relationship among in distributed hardware, household appliances, mobile equipment and software objects . Based on the introduction of the workflow of information appliances system and the consideration of the object-oriented nature of Information Appliance， put forward the concept of service locator. First,I describe the service locator should have the functions.Then,according to the functions of service locator design its functional components. Finally, o n the basis of above, explaining principle of the service locator. Key Words: System of Information Appliance, search, find Service Locator，IAServiceID 1.引言
