摘要：物联网技术发展极其迅速，目前已涉及到农业、食品安全、智能交通、电力系统等各个行业。每一个完整的物联网产品都是在智能网关的综合控制和管理下进行工作，所以物联网智能网关在整个系统中尤为重要。然而国外的物联网却领先国内将近10年的技术水平，国内物联网的发展正在如火如荼地进行，智能网关能够实现的功能和技术点是体现国内物联网发展水平的重要体现。
本文首先介绍了智能网关设计的总体构架并对软硬件的选型和功能实现作了详细介绍，主要运用到的硬件设备有W5500芯片、CC2530芯片、51单片机等，其中51单片机是调试硬件；操作系统为OSAL，运用到Zigbee-Stack协议。23950

Study on the design of intelligent gateway of the Internet of things
Abstract: Interact of things over the Interact based on the concept put forward is to extend and expand its client between any goods and goods to the exchange of information and communication of a network concept．The further development of networking technology,in fact，promotes seamless interactive technology．The so-called seamless interaction，that is，the full realization of the computer design of the digital world and physical world is tightly integrated way．
This article first introduces lightweight protocols and embedded operating system，Z-Stack
，the establishment of a standardized，open network server architecture，its architectural style is based on the most basic of network protocol has able to send short messages，radio-- Subscribe to the mechanism and the authentication mechanism and the protection of data security and other functions，is also a lightweight，scalable and good，open—ended．Then the test platform, successfully transplanted to W5500 within the protocol. Again, for wirelesssensor CC2530 and connectivity,and with the Internet connectivity was proposed design idea and made a test lab．Finally,in the above experiment is proposed based on test platform based on the external hardware circuit design ideas and hardware circuit design．
