【摘要】：在互联网基础上提出的“物联网”技术及其近段时间的迅速发展,使得物联网技术在未来国民经济生产、生活中将会占据着越来越重要的位置,势必会发挥出越来越重要的意义。物联网网关的主要目的是在广域互联或者是局域互联的区域内实现感知网络与通信网络以及不同类型感知网络之间的协议转换,从而构建整个物联网系统。因此,物联网嵌入式通信系统网关的研究及组网实现实际是构建整个物联网系统的至关重要的环节,那么,按照专用性强、实时性好、可靠性高、功耗少、体积小和低成本的需求,如何建立网络层的协议转换器,如何采用先进技术实现物联网网关的灵活性、低成本成为了现在物联网技术研究的重要课题之一。基于此,本文分析、设计了一个基于嵌入式系统的物联网网关通信系统设计方案。本方案采用嵌入式系统、无线传感器网络技术、IEEE802.15.4技术标准,通过ZIGBEE节点将网络与Internet连接在一起,从而实现对ZIGBEE网络中的所有设备节点的有效监控与检测,最终实现物理世界的空间距离,真正达到低损耗、小体积、低成本的技术需求。本文首先分析了研究课题的研究背景与意义,归纳总结了国内外研究现状及其未来可能的发展趋势。然后,确定了系统整体设计方案及其相应技术参数分析。再则,具体设计实现了物联网嵌入式通信系统的硬件部分与软件部分,并对其进行了相应测试分析,其结果表明,本文所设计的物联网嵌入式通信系统具有一定的市场推广价值。
[Abstract]:The "Internet of things" technology proposed on the basis of the Internet of things and its rapid development in the recent period of time, make the Internet of things technology in the future national economic production, life will occupy an increasingly important position. It is bound to play a more and more important role. The main purpose of Internet of things gateway is to realize the protocol conversion between perceptual network, communication network and different types of perceptual network in the area of wide area interconnection or local area interconnection, so as to construct the whole IoT system. Therefore, the research of the gateway of the Internet of things embedded communication system and the realization of the network are the most important links in constructing the whole IOT system. Then, according to the strong specificity, good real-time, high reliability, low power consumption, With the demand of small volume and low cost, how to set up the protocol converter of network layer and how to use advanced technology to realize the flexibility of Internet of things gateway, low cost has become one of the important research topics of Internet of things technology. Based on this, a design scheme of Internet of things gateway communication system based on embedded system is designed. This scheme adopts embedded system, wireless sensor network technology and IEEE802.15.4 technology standard, and connects the network with Internet through ZIGBEE node, thus realizes the effective monitoring and detection of all device nodes in ZIGBEE network. Finally, the space distance of the physical world is realized, and the technical requirements of low loss, small volume and low cost are achieved. This paper first analyzes the research background and significance of the research topic, summarizes the domestic and foreign research status and possible future development trend. Then, the overall design of the system and the corresponding technical parameters are analyzed. Furthermore, the hardware and software parts of the embedded communication system of the Internet of things are designed and implemented, and the corresponding test analysis is carried out. The results show that, The embedded communication system designed in this paper has certain market value.
