基于LoRa的智能灌溉监控系统在灌区中的应用

Application of Intelligent Irrigation Monitoring System Based on LoRa in Irrigation Area

为提高农业灌溉用水效率,解决灌区水资源浪费情况,设计了一种基于LoRa技术的节水灌溉智能监控系统。该系统通过在灌区布设LoRa信息采集终端节点和流量传感器对水量进行监测;通过水权分配和水价改革实行阶梯水价,并配备刷卡取水装置对水费进行精准计量,实现灌区水资源的高效利用;灌区信息中心软件平台对相关数据信息进行存储、查询、统计等,实现灌区节水灌溉与自动监控。测试结果表明:该系统具有远距离、低功耗和造价低等特点,将自动化灌溉与水价改革结合,达到节水灌溉的目的。

In order to improve the efficiency of irrigation water for agricultural irrigation and to solve the waste of water resources in irrigation area,this paper designed a kind of an intelligent monitoring system for water-saving irrigation based on LoRa technology.The system monitored the water volume by setting up the LoRa information acquisition terminal nodes and flow sensors in the irrigation area;implemented ladder water price through water rights allocation and water price reform and equipped with swipe card and water intake device to measure water charges accurately,so as to achieve efficient utilization of water resources;the information center software platform stored,inquired and counted the relevant data and information to realize water saving irrigation and automatic monitoring.The test results show that the system has the characteristics of long distance,low power consumption and low cost.It combines automatic irrigation with water price reform to achieve the purpose of water-saving irrigation.
