Abstract: With the concept of building national smart grid, smart meter has become the focus of people′s attention. In order to read and manage the user′s electricity consumption more conveniently, accurately and timely, and realize the automation and networking of smart meters, this paper designs a relay multi hop networking protocol based on LoRa, and through the design of software and hardware of smart meter and collector, completes the transplantation and implementation of this protocol in smart meter communication, and designs a new communication scheme of smart meter. This scheme starts from the communication performance and applicable scenarios, on the basis of LoRa communication, further improves the performance of LoRa communication through relay multi hop networking protocol, and realizes a new communication scheme with high capacity and high reliability.
Key words : LoRa;intelligent meter;relay multi hop networking;communication scheme

當(dāng)前新型智能電表普遍采用無(wú)線通信方案,無(wú)線通信技術(shù)有GPRS、ZigBee、LoRa等。在無(wú)線通信技術(shù)中,遠(yuǎn)程(Long Range,LoRa)是一種采用擴(kuò)頻技術(shù)的無(wú)線傳輸方案,具有遠(yuǎn)距離傳輸、抗干擾能力強(qiáng)、低功耗等特點(diǎn)[1-2],其特性適合用于智能電表的通信。但其也存在著可靠性低、容量過(guò)少的問題[3-5]。因此,本文研究一種基于LoRa的使用新型組網(wǎng)協(xié)議的通信方案,致力于消除LoRa的不足,使其更加適合于智能電表通信。
