基于LoRaWAN的农田环境监测系统设计

Design of Farmland Environment Monitoring System Based on LoRaWAN

针对农田监测出现的系统覆盖范围小、对蜂窝信号要求高、系统成本高等问题,设计了一种基于LoRaWAN的农田环境监测系统。该系统终端以STM32L051为主控芯片,利用传感器采集农田环境数据,并将数据通过LoRaWAN传输到网关,网关将数据转发到MQTT服务器,再通过可视化云监测平台进行显示,形成一种覆盖范围广、功耗低的远距离农田环境监测系统。该系统对蜂窝信号要求低,可以极大地降低系统的投入成本,非常适合户外大规模农田环境的监测。

Aiming at the problems of small coverage, high requirements for cellular signals and high cost in farmland monitoring, a LoRaWAN-based farmland environment monitoring system is designed. The system terminal with the STM32L051 as the main control chip, uses sensors to collect farmland environmental data, and transmits the data to the gateway through LoRaWAN. The gateway forwards the data to the MQTT server, and then displays it through the visual cloud monitoring platform, which builds a long-distance farmland environment monitoring system with wide coverage and low power consumption. The system has low requirements for cellular signals, which can greatly reduce the input cost of the system, and is very suitable for the monitoring on the outdoor large-scale farmland environment.
