基于ZigBee、以太网、WiFi技术的网关设计

针对适用于教学仪器市场的物联网产品比较少以及与学校自主研发产品不兼容的情况,设计并实现了基于无线传感网技术的测控子系统.该子系统由数据采集与控制节点、网关、服务器和上位机4部分组成.其中,网关是数据采集控制节点和服务器的通信桥梁.网关采用STM32F103VET6和CC2530双处理器架构.首次将逆向云算法应用到物联网网关中,使网关具有自适应性和智能性.详细介绍了测控子系统中网关架构、软硬件设计、通信协议和逆向云算法.实验结果表明,本设计能满足系统各项要求,具有良好的可靠性.

Design of Gateway Based on ZigBee,Ethernet and WiFi Technology

To solve the problems that Internet of things(IOT) product is relatively less and not compatible with self-developed product in teaching instrument market,a measurement and control subsystem based on WSNs is designed and realized,which consists of data acquisition and control nodes,gateway,server and upper computer.Among them,the gateway based on STM32F103VET6 and CC2530 dual architectures is communication bridge between data acquisition and control nodes and server.The backward cloud algorithm is first time applied to IOT gateway,which makes the gateway have adaptability and intelligence.The designs of gateway architecture,software and hardware,communication protocol and backward cloud algorithm are introduced.The experimental results show that the design can meet the requirements of the system,and has good reliability.
