摘 要:本文基于ZigBee 技术、STM32F103 单片机设计了一种基于物联网的智能喷灌系统,借助ZigBee 技术搭建一个无线传感网络,系统能够实现对土壤墒情的自动判断并做出相应的控制。系统通过各分布式节点采集农作物生长环境的温度和湿度等信息,利用ZigBee 无线通信技术传送至主控器,主控系统通过分析计算各节点信息实现对喷灌设备的控制,从而实现自动改善土壤环境的作用。同时,主控系统可将相关信息实时传送至用户移动设备,实现远程监控与管理。该系统的应用能够降低劳动者工作强度,克服根据人的经验决定灌溉时间和灌溉水量的缺点,提高水资源的利用率,实现对农作物灌溉的科学管理。

Abstracts:Based on ZigBee technology and STM32F103 single-chip microcomputer,this paper designed a control system for crop sprinkler irrigation,which can realize automatic determination of soil moisture and make corresponding control. The system collects the temperature,humidity and other information of the growing environment of crops through distributed nodes,and uses ZigBee wireless communication technology to transmit it to the master controller. The master control system realizes the control of sprinkler irrigation equipment by analyzing and calculating the information of each node,so as to automatically improve the soil environment. Meanwhile,the main control system can transmit the relevant information to the user’s mobile devices in real time to realize remote monitoring and management. The application of this system can reduce the working intensity of laborers,overcome the shortcomings of determining irrigation time and water amount according to human experience,improve the utilization rate of water resources and realize scientific management of crop irrigation.
Keywords:ZigBee;wireless sensor network;intelligent sprinkler irrigation;ad-hoc network
