【摘要】 随着建设国家智能电网概念的提出,智能电表开始成为人们关注的焦点。为了更加方便、准确、及时地对用户用电量进行抄读与管理,实现智能电表的自动化、网络化,设计了一种基于LoRa的中继多跳组网协议,并通过对智能电表和采集器的通信模块进行新型软硬件设计,来实现此协议在智能电表通信方案中的移植和使用,进行智能电表的新型通信方案设计。该方案从通信性能及适用场景出发,在LoRa通信的基础上,通过中继多跳组网协议进一步提升LoRa通信的性能,实现了高容量、高可靠性的新型通信方案。更多还原

【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.更多还原
