摘　　要：文章介绍了面向大田、果林等野外环境下农作物监测终端的组网系统设计。由于农作物生长环境具有遮挡小、面积广等特点,常用的Wifi、Zigbee、NBIOT、蓝牙等短距离无线通信技术在此环境下应用有一定局限性。故设计一套基于LoRa低功耗长距离无线通信技术的新系统,实现了低功耗和远距离的统一,传输距离达到传统方案的3-5倍。同时为了系统数据可视化,在网关端搭建嵌入式BOA服务器,实现了观测结果的跨平台访问。This paper introduces the design of the network system for crop monitoring terminals in field environments such as field and fruit forest.Because the crop growth environment has the characteristics of small blocking,wide area and so on,commonly used Wifi,Zigbee,NBIOT,Bluetooth and other short-range wireless communication technology in this environment has certain limitations.Therefore,a new system based on LoRa’s low-power long-range wireless communication technology is designed to achieve the unification of low power consumption and long distance,and the transmission distance is 3-5 times that of the traditional scheme.At the same time,in order to visualize the system data,the embedded BOA server is set up at the gateway end,and the observation results are accessed across platforms.
