摘要: 针对智慧城市建设对数据资源的基础性需求,提出一种基于6LoWPAN无线传感器网络技术的数据采集系统设计方案。基于C/S模式实现数据服务器从底层网络获取数据,在提高灵活性的同时,提升有效数据流量比。通过6to4隧道与Netfilter框架设计基于网络层的嵌入式网关,实现6LoWPAN网络与以太网的融合,同时提高网关的适应性,降低小数据包平均转发时延和丢包率。数据消费端与数据服务器之间基于C/S架构设计,既保证数据消费端能根据应用对象的不同而独立设计,又可以降低数据服务器端的复杂度。测试结果表明,提出的方案可行性高、组网方便、易于维护和升级。

Abstract: A data acquisition system design scheme based on 6LoWPAN wireless sensor network technology is proposed to meet the basic needs of data resources in the smart city construction process.Based on the C/S architecture,the data server can obtain data from the bottom network,which improves the flexibility and increases the effective data flow ratio at the same time.By designing the embedded gateway based on the network layer with 6to4 tunnel and Netfilter frame,the integration of 6LoWPAN network and the Ethernet is realized.Meanwhile,the adaptability of the gateway is improved,the average forwarding delay of small packets and the packet loss rate can be decreased.C/S architecture is applied between the data consumption terminal and the data server,this can not only ensure the independent design of data consumption terminal according to different application objects,but also reduce the complexity of the data server.Test results show that the proposed system is feasible,convenient to network,easy to maintain and upgrade.

Key words: smart city, data acquisition, 6LoWPAN technology, 6to4 tunnel, embedded gateway, C/S architecture
