当前数字家庭中设备间的互联互通成为研究热点。针对嵌入式智能设备间的多媒体文件共享问题，提出一种基于UPnP （ Universal Plug and Play）设备模型的多媒体文件共享方法。首先研究UPnP技术的工作原理，分析其协议栈和工作流程，然后详细介绍系统的架构设计和模块实现，并给出应用流程分析，最后在家庭网络环境下进行测试验证。此外，为保证多媒体共享文件的安全性，提出一种基于UUID和用户选择的访问控制策略，并在实际系统中验证了该策略的有效性。

Nowadays, the interconnection between devices in digital home becomes a hot research topic.Aiming at the problems of multi-media files sharing between embedded intelligent terminals, we proposed a UPnP device model-based multimedia files sharing method.First, we studied the working principle of UPnP technology, and analysed its protocol stack and working process.Then, we introduced in detail the architecture design and module implementation of the system, and presented the analysis of application process.At last, in home network en-vironment the verification is tested.Furthermore, in order to guarantee the security of the sharing multimedia files, we proposed an access control strategy which is based on UUID and user selection, and validated its feasibility in practical application.
