摘　　要：基于IPv6的低功耗无线个域网(6LoWPAN)标准是一种适配IEEE 802.15.4和IPv6协议的技术,与其他无线个域网技术相比,接入设备不需要复杂的网关或代理即可直接与IP网络通信。基于6LoWPAN架构设计的环境监测系统,主要包括传感器、6LoWPAN终端节点、6LoWPAN网关、Web应用服务器4个部分。其中6LoWPAN网关使用HG553硬件平台并基于Open Wrt开发,6LoWPAN终端节点采用Modbus-RTU协议与传感器通讯采集数据。系统工作时采集数据经过网关上传到Web应用服务器的数据库,由Web应用服务器对传感数据进行管理、分析,最终实现环境监测服务。IPv6 based Low power Wireless Personal Area Network （6LoWPAN） is a simple low-cost protocol that allows network devices access internet seamlessly through IEEE 802.15.4 and IPv6 protocol.Compared with wireless personal area net- work,the advantage of 6LoWPAN is the ability to communicate with other IP network directly without complex gateway.An envi- ronmental monitoring system was designed based on 6LoWPAN technology,which is mainly composed of four parts including ter- minal sensors ,6LoWPAN terminal nodes ,6LoWPAN gateway and web server.The gateway based on OpenWrt system in the plat- form of HG553.6LoWPAN terminal nodes communicated with terminal sensors using the protocol of Modbus-RTU and uploaded the acquired data to web service＇s database.According to the test results,our system is able to implement the data acquisition and transmission reliably and provides the environmental monitoring service stably.
