摘要
无线抄表因具有无需布线、施工方便的特点而逐渐得以广泛应用,目前国家电网已经在Sub-GHz频段中部署了微功率无线通信协议用于数据的传输。基于VC实现MAC层、网络层、应用层的设计,基于LabVIEW语言实现了物理层功能,从而构建了智能无线抄表协议栈,同时,采用USRP设备作为射频前端进行节点电能信息的收集和数据的收发。所提出的协议栈易于开发、系统兼容性强,具有较高的推广应用价值。
Wireless meter reading has been widely used because of its advantages of no wiring and convenient construction.At present,the State Grid has deployed micro power wireless communication protocol in sub-GHz frequency band for data transmission.This paper realizes the design of MAC layer,network layer and application layer based on VC,realizes the function of physical layer based on LabVIEW language,and constructs intelligent wireless meter reading protocol stack.At the same time,USRP device is used as RF front-end to collect node power information and send and receive data.The protocol stack designed in this paper is easy to develop and has strong system compatibility,so it has high application value.
