基于LoRa的智能灌溉系统设计

Design of Intelligent Irrigation System Based on LoRa

摘要:

针对传统人工灌溉所带来的水资源利用率低、人力资源浪费等问题,提出了一种基于LoRa的智能灌溉系统设计方案。LoRa是一种基于扩频技术的超远距离无线传输方案,最大程度地实现更远的通信距离与更低功耗。通过设计基于LoRa通信技术的光照强度,空气温、湿度以及土壤湿度等信息的采集单元,通信网关,结合水阀控制单元以及智能管理PC端灌溉控制平台软件设计,实现自动或手动灌溉模式。实验数据表明,所设计的灌溉系统灌溉方式灵活多样,智能高效,实用性强,满足系统需要,可以实现灌溉作业的精细化管理。

Abstract:

In view of the problems of traditional irrigation, such as waste of water resources and waste of human resources, the paper presents a design scheme of intelligent irrigation system based on LoRa. LoRa is an ultra-long-range wireless transmission scheme based on spread spectrum technology to maximize communication distance and lower power consumption. The automatic or manual irrigation mode is designed by designing the software of light harvesting, air temperature, humidity and soil moisture based on LoRa communication technology, communication gateway, combined water valve control unit and intelligent management of PC-side irrigation control software. The experimental data show that the designed irrigation system has flexible irrigation methods, intelligent and efficient, practicality, and meets the needs of the system, so as to achieve refined management of irrigation operations.
