Research Of Agricultural Greenhouse Monitoring System Based On Webgis And Internet Of Things

As China has a large population and little arable land,traditional agricultural is characterized by low production efficiency and low informatization,which is the bottleneck of China's agricultural modernization.With the development of wireless sensing technology,communication technology and intelligent control technology,the Internet of Things technology has been widely applied to agricultural production to realize the automatic management of agriculture and improve labor efficiency.In this paper,the WebGIS system and the Internet of Things technology are applied to the monitoring system of agricultural greenhouses.The powerful spatial visualization capability of WebGIS is utilized,so that the 'point' based monitoring can be integrated with the spatial data ‘face'.And the users can observe sensor acquisition more intuitively.The environmental factors such as air temperature and humidity,carbon dioxide concentration and other data in the greenhouse,the environment inside the greenhouse can be adjusted through environmental regulation equipment,and control algorithms can be used to realize automatic control and management of greenhouses.Based on the WebGIS and the Internet of Things,this paper first discusses the background and significance of the research on the monitoring of agricultural sheds and the development status of the monitoring system for agricultural greenhouses at home and abroad,and then describes the key technologies and related knowledge theories of the realization process of the agricultural shed monitoring system.On the basis of system analysis,combined with the actual needs of the users,this paper first designed the overall system,including data acquisition module,system cloud base station and remote monitoring system in three parts.By installing data acquisition nodes(sensors,cameras)in the greenhouse,users can monitored the growing environment of crops in real time.The system uploads the monitored data to the system cloud base station and sends the data to the remote monitoring system.Then the user can preview the environmental information in the greenhouse through the web page of the front desk,and send control commands to the base station to operate(adjust the temperature,humidity,ventilation,etc.)the equipment in the greenhouse according to past planting experience,and adjust the environment inside the greenhouse to ensure that the crop is in a suitable growth environment.Finally,the functional modules and the overall system of the agricultural greenhouse monitoring system were tested.The test results show that the Socket communication service between the various parts of the system is normal and the system includes map monitoring module,growth model module,environmental information module,equipment information module,analysis chartmodule,system management module,notification management module,equipment management module,business management modules and other modules can operate stably.
