智慧温室群远程监控系统通信设计

温室监控系统是对温室环境中温度、湿度、光照度等环境因子实施监测与调控的农业设施，可确保农作物获得最适宜的生长发育环境。针对现有温室监控系统在通信上存在距离受限、组网复杂、能耗高且基本仅能实现单个温室控制的问题，设计了一种基于LoRa和NB-IoT相结合的智慧温室群远程监控系统通信模式。该模式以STM32F103C8T6单片机为核心控制器件，采用ATK-LoRa SX1278和NB-IoT模块自组无线通信网实现数据的远程交互。测试结果表明：采用该通信模式可实现温室群中各温室间距离在2km范围内的数据采集、处理和传输，其通信距离远、功耗低，数据传输可靠性符合现代化农业物联网的需求。

Communication Design of Remote Monitoring System for Intelligent Greenhouse Group

A greenhouse monitoring system is an agricultural facility which monitors and controls environment factors such as temperature, humidity and illumination in a greenhouse environment to ensure the most suitable growing environment for crops. Aiming at the problems of limited distance, complex networking, high energy consumption and independent control in the communication of the existing greenhouse monitoring system, a communication mode of intelligent greenhouse group remote monitoring system based on the combination of LoRa and NB-IoT is designed in this paper. It uses STM32F103C8T6 single-chip microcomputer as the core control device and uses ATK-LoRa SX1278 and NB-IoT module to implement the remote data interaction. The test results show that the communication mode can achieve data collection, processing and transmission within 2km the greenhouse group. Its long communication distance, low power consumption and data transmission reliability can meet the requirements of modern agricultural internet of things.
