【摘要】 3G和物联网无疑是目前信息领域最热门的词汇。物联网是在互联网概念的基础上提出的。物联网将信息传感设备和互联网结合起来形成一个网络,进行信息交换和通讯,以实现智能化识别、定位、跟踪、监控和管理的一种网络。开发支持3G的通讯设备已经成为通讯产业和嵌入式系统发展的热点。3G技术关键还是在于服务,物联网是3G非常重要的应用。在构建物联网体系结构,网关是非常重要。对于物联网来讲,网关是连接传感网络与互联网或其它智能设备的桥梁。本文以3G技术发展为契机,以物联网为背景,提出了一种基于3G的物联网网关的设计思想,设计了具体的实现方案。本文设计了一种基于ARM和Windows CE的嵌入式物联网网关的方案。在此基础上提出了基于ZigBee技术、3G技术和GPRS技术的无线网络组网方案,实现了网关广泛接入能力的功能。软件设计方面,网关应用程序利用Visual Studio2005编写。应用程序主要负责完成ZigBee协议与TCP/IP的协议转换,并实现了Zigbee网络与Internet的互联互通。最后,对ZigBee技术的抗干扰特性进行分析。分析了ZigBee技术与其他2.4GHZ频段技术共存的问题,并提出了共存问题的解决方案更多还原

【Abstract】 3G and the Internet of Things are undoubtedly the most popular words in the information field. And Internet of things has been put forward based on the concept of the Internet.Internet of Things means a network that formed by information sensing devices combined with the Internet, it exchanges information and communicates to realize intelligent identification, location, tracking and monitoring and management. Research and development of electronic device which supporting the 3rd-generation communication technology has become the focus of the communication industry and embedded systems. The key of 3G technology still lies in services, and Internet of Things is very important to 3G applications. The development of the Gateway is very important to build Internet of Things’ architecture. As the Internet of things is concerned, Gateway is connected to a sensor network and the Internet, or other smart devices as a bridge.On the chance of the development of 3G technology, background of the Internet of things, a thought and design of Internet of things gateways based on the 3G is brought forward with specific implementation.The thesis has proposed a kind of design that embedded Internet of things gateways based on ARM and Windows CE. On this basis, it has also proposed wireless network technology network solutions based on ZigBee technology,3G technology and GPRS, to achieve broad access gateway function.In the design of software, Visual Studio 2005 is used to design the software which function is to transform protocols between Zigbee and TCP/IP, and realize the inter-connecting between Zigbee network and Internet.Finally, this paper analyses the characteristics of anti-interference of ZigBee and the problem of ZigBee technology co-exist with other 2.4GHZ frequency band technology, and puts forward the coexistence of the solution.更多还原
