The Design And Research Of Precision Agricultural Greenhouse Monitoring System Based On The Internet Of Things

In our country, the traditional way of farming can not meet the requirements ofreasonable farming due to the big difference in social and natural conditions in differentregions. In the meanwhile, with the development and application of the internet of things,it is very important to develop an agricultural greenhouse motoring system that is suitableto our national conditions. The precision agricultural greenhouse monitoring system,through the system, on the one hand, we can control the temperature, humidity and thecarbon dioxide concentration to improve the growth of the crops and increase theproduction, on the other hand, we can realize automatic monitoring of the growth processof the crops.The thesis analyses the background meaning and the current situation of the precisionagriculture in home and abroad. The thesis mentions some technology support about theinternet of things and the precision agriculture, and brings forward the design plan aboutprecision agricultural greenhouse monitoring system based on the internet of things. Thesystem analyses from three aspects: the collection of data nodes, the base station and theremote monitoring system. We can monitor the environment of the crops through theterminal sensors (such as the temperature sensors, the humidity sensors and so on) weinstalled in the greenhouse, and we can upload the data to the base station. The base stationsystem decides whether to alarm or not based on the former data setting, at the same time,the base station sends the data to the remote host computer. The workers should comparethe data of the host computer with the actual situation of the crops and then send controlorders to the base station to operate the equipment in the greenhouse (to adjust thetemperature, humidity, ventilation and so on).In the thesis, the main methods I use are literature survey, system analysis,experimental method and problem analytic method. I come up with a design plan aboutprecision agricultural greenhouse monitoring system. It includes five parts: the greenhousedata management,the sensor management, the greenhouse management orders control, theuser management and the user rights assignment.
