Research on the agricultural greenhouse environment monitoring system design based on Internet of Things technology

文章通过对农作物的生长环境进行监控,设计了一套监控系统。根据物联网技术的三层结构,即感知交互层、网络传输层和应用服务层建立系统的结构。通过使用物联网技术,对农业大棚空气温度、湿度、光强度和其他环境数据进行实时监控。通过Dempster-Shafer证据推理法对传感器收集到的数据进行信息处理并将其传送到监控终端平台以实现显示。仿真结果表明通过Dempster-Shafer证据推理法所得的数据可靠性显著提高。利用Matlab软件进行仿真实验,结果显示系统运行良好,通信正常。经处理后的通信数据曲线更平滑,大大减少了数据误差。

This paper designs a monitoring system to monitor to control the growth environment of the crops. On the basis of the three-tier structure of the Internet of Things （IoT）, aware interactive layer, network transport layer, application service layer, it builds the structure of system. The environmental data of agricultural greenhouse including air temperature and humidity, light intensity and others axe monitored and controlled by the use of things technology in real time. The data collected by sensor are processed through Dempster-Sharer and then sent to monitor terminal platform to display. Simulation result shows that the reliability of the data coming from Dempster-Shafer is remarkable improved. We make use of Matlab soft to do the simulation experiment, and the system runs well, and communication is normal. The curve of communication data after processing appears smoother. The data error are reduced dramatically.
