摘要
以LoRa为代表的低功耗、远距离网络技术的出现,有效解决了物联网复杂组网和超高功耗的难题。为进一步降低基于LoRaWAN的无线抄表系统的功耗,同时针对ZigBee、红外等无线技术在抄表方案中存在通信距离短、抗干扰能力弱的缺陷,通过对LoRaWAN无线标准协议的研究,将MCU系统和LoRa技术相结合,设计了一种基于LoRaWAN无线通讯技术的智能抄表系统。首先介绍无线抄表系统的硬件组成和功能模块的作用,其次介绍节点软件设计过程,最后得出结论,该系统实现了降低功耗的作用。
LoRa represented in low-power, long-distance network technologies appears to effectively solve the complex networksand ultra-high-power networking problems. In order to reduce the power consumption and of the wireless meter reading systembased on LoRaWAN,at the same time for the Zigbee and infrared wireless technology in the meter reading scheme defects of shortcommunication distance and weak anti-interference ability.Through the research of LoRa wireless standard protocol, combining theMCU system and LoRa modulation technology, an intelligent meter reading system based on LoRa wireless communication technol-ogy is designed. First introduces the hardware structure of the wireless meter reading system and the function of function module.Secondly, communication protocol and node software design process are described. Finally, the results show that the system can re-duce the power consumption.
