摘要
该文介绍了LoRa无线通信技术和MQTT协议的发展概况及基本原理,并基于LoRa技术和MQTT技术开发了一种物联网型风速风向监测系统。该系统专门设计了一种基于超声波风速风向传感器和气象气球的便携式监测节点,使现场操作人员可以在无需专门铺设通信和供电线路的情况下通过布置多个监测节点和唯一的LoRa集中器实现较大范围内特定高度的风速风向信息采集;系统设备的状态信息和集监测节点采的风速风向数据在本地数据存储设备中保存的同时被上传至MQTT云端服务器,再由云端服务器转发至用户服务器以供使用。
This paper introduces the development and basic principle of LoRa wireless communi-cation technology and MQTT protocol,and develops a wind speed and direction monitoring system based on LoRa technology and MQTT technology.The system specially designed a kind of portable monitoring node based on ultrasonic wind speed and direction sensor and weather balloon,which enables the field operators to collect wind speed and direction information in a large range at a specific height by arranging multiple monitoring nodes and a unique LoRa concentrator without special laying of communication and power supply lines.The status information of system equipment and the wind speed and direction data collected by the centralized monitoring node are saved in the local data storage device and uploaded to the MQTT cloud server,which then forwards to the user server for use.
