LoRa无线数据传输模块的设计与实现

Design and Implementation of Wireless Data Transmission Module Based on LoRa

针对现有无线数据传输模块功耗高、传输距离短、可靠性低的缺陷,该文提出了一种新型的基于LoRa技术的无线数据传输模块。该模块以SX1276为射频芯片,采用低功耗微处理器STM8L151为主芯片并移植了Contiki嵌入式操作系统。该文详细介绍了数据传输模块的硬件设计、软件设计并测试了模块的主要性能。测试结果表明,该数据传输模块具有功耗低、传输距离远、可靠性高等优点,适用于无线抄表、环境监测等系统中。

Existing wireless data transmission modules have some disadvantages,such as high power consumption,short transmission distance,low reliability and high cost.In this paper,a new design of wireless data transmission module based on LoRa was proposed.The module uses SX1276 as the radio frequency chip and the low-power microprocessor STM8L151 as the main chip,and embeds the contiki operating system.We discuss the design of hardware and software in this module,and evaluate its performance.The final tests indicate that the proposed wireless transmission module has advantages of low power consumption,long transmission distance and high reliability.It is suitable for use in wireless meter reading and environmental monitoring systems.
