摘　　要：在传统物联网的基础上,提出低功耗广域LoRa的解决方案。设计一套由采集层、终端层和应用层组成的物联网架构并设计系统原型,介绍架构的硬件设计和软件设计,实现了物联网低功耗广域接入技术。最后通过其实例应用,展示LoRa的应用前景。该系统充分发挥了LoRa技术在高性能、远距离、低功耗,支持大规模组网、测距和定位等方面突出的优点,对未来物联网系统的设计、开发、部署和运营具有一定意义。This paper presents a low-power and wide-area solution based on LoRa and traditional Internet of Things （IoT） technologies. By designing the lot architecture composed of acquisition layer, terminal layer and application layer, the hardware design and software design of the architecture are introduced in detail, and the low-power and wide-area access technology of lot is realized. Finally, the application scenarios of LoRa are demonstrated. This system takes full advantage of LoRa technology in high performance, long distance, low power consumption, large-scale networking, distance measurement and location. it has a certain significance for the design, development. deployment and operation of the IoT system.
