摘　　要：针对现有温室监控系统存在距离短、布线难、能耗大、可靠性差且多个温室不能同时监控的问题,设计一种基于LoRa技术的温室群远程监控系统。选择以STM32F103C8T6处理器、SX1278无线芯片和DHT11温湿度等传感器组成精简的低功耗节点硬件电路,采用定时收发的方式设计自组网协议,结合节点、网关和上位机软件设计,实现温室群(各温室间直线距离在2 KM范围内)中各环境因子的远程监控,通过实验验证了系统的连通性、实时性、可靠性和可操作性。Aiming at the problems of the existing greenhouse monitoring system such as short distances,difficult wiring,large energy consumption,poor reliability,and also multiple greenhouses cannot be monitored at the same time when using the met-hod,a remote monitoring system for greenhouses group based on LoRa technology was designed.STM32F103C8T6 processor,SX1278 wireless chip,and DHT11 temperature and humidity sensors were used to form a simple low-power node hardware circuit.Ad hoc network protocol was designed by using timing transmission and reception.The combination design of node,gateway and upper computer software realized the remote monitoring of environmental parameters in greenhouse group(the straight-line distance among greenhouses is within 2 KM),and the connectivity,real-time,reliability and operability of the system are verified through experiments.
