摘要
为了提高作物生长环境的监控水平,设计了基于433 MHz无线通信技术和NB-IOT技术的农业环境监控系统,介绍了系统的总体设计和软硬件设计。该系统将433 MHz无线传感网络与Modbus协议相结合,通过检测模块完成环境参数的采集,再通过433 MHz无线传感网络和窄带物联网NB-IOT技术实现数据的远程传输。系统根据检测到的环境参数自动控制设备来调节环境。该系统充分利用了NB-IOT技术的优势,具有功耗低,可靠性高,成本低等优点,具有广阔应用前景。
In order to improve the monitoring level of crop growth environment,this paper puts forward an agricultural environmental monitoring system based on 433MHz wireless communication technology and NB-IOT technology.The overall design of the system and the design of the software and hardware are introduced in this paper.The system combines the 433MHz wireless sensor network with the Modbus protocol,and the system completes the collection of environmental parameters through the detection terminal,and the remote transmission of data is realized through the 433MHz wireless sensor network and the narrow-band network NB-IOT technology.The system controls the environment automatically according to the detected environmental parameters.The system makes full use of the advantages of NBIOT technology,and it has the advantages of low power,high reliability and low cost,which has broad application prospect.
