基于LoRa的农田土壤墒情监测系统设计

Design of farmland soil moisture monitoring system based on LoRa

为了解决土壤墒情监测系统中存在通信距离受限、功耗大、无法组网的问题,研制了一种基于LoRa的农田土壤墒情监测系统,进行土壤墒情监测信息的远程传输、控制、显示。将土壤水分传感器采集到的墒情数据通过LoRa通信模块上传至网关,网关汇集数据后再传输到远程监测平台,形成了一套监测范围广、低功耗、灵活组网而且远距离通信的农田土壤墒情监测系统。该系统提高了土壤墒情监测的工作效率,适用于户外大面积农田的数据监测与采集站点多的场景,为土壤墒情自动化远程监测提供一种新的技术方案。

In order to solve the problems of limited communication distance,large power consumption and no extensive network in soil moisture monitoring system,a field soil moisture monitoring system based on LoRa was developed,remote transmission,control and display of soil moisture monitoring information.The soil moisture data collected by the soil moisture sensor was uploaded to the gateway through the LoRa communication module,and the gateway collects the data and transmits it to the remote monitoring platform,a moni⁃toring system of soil moisture in urban farmland with wide monitoring range,low power consumption,flexible network and long-dis⁃tance communication was constructed.The system improves the working efficiency of soil moisture monitoring,and is very suitable for the scene where there are many data monitoring and collecting stations in large-area farmland.
