摘 要：In order to provide the environment for the growth of a crop monitoring program,design a monitoring system.In accordance with three-tier structure of the Internet of Things,the structure of system is built by the way of using aware interactive layer,network transport layer,application service layer.By using Things technology the function of monitoring and controlling the agricultural greenhouse air temperature and humidity,light intensity and other environmental data is implemented.The data that sensors have collected is processed by Bayes filtering and sent to the monitoring terminal platform to display.The simulation results show that reliability of data through the Bayes filtering is enhanced.By making the MATLAB software simulation experiment the results show that the system is running well,the communication is normal,and after the filtering process the monitoring data curve is smoother,reducing data errors.
