Research And Development Of Agricultural Greenhouse Environment Intelligent Acquisition System Based On Wireless Transmission Network

Agriculture is vital to human’s life since it can provide us with food and the source of clothing.It is also the basis of other production.In China,with the increasing of the number of agricultural greenhouses,the management the traditional agricultural greenhouse can not follow the step of the times.According to the analysis of the management technology of existing agricultural greenhouse and the research on wireless sensor network.We design a set of intelligent greenhouse environment acquisition system based on wireless sensor network which uses multiple sensors to collect greenhouse environmental data in this paper.Farmers can use the client to check the environmental data and the control the equipment inside the greenhouse remotely to realize the intelligent.This is of significance to the development and promotion of wireless sensor networks in agricultural greenhouses since it can help to realize the automated and scientific management of the agricultural greenhouse environment.An intelligent greenhouse environment collection system based on wireless sensor network is developed in this paper which has the advantage of low cost,easy operation,intelligence and high reliability.It uses existing ZigBee wireless sensor network technology,microcontroller technology and acquisition module to collection of crop growth environment real-timely.The harvesting environment is collected by the temperature and humidity sensor,the light sensor,the carbon dioxide sensor,etc.,and then transferred to the node to the gateway which is consist of STM32F103RBT6 microcontroller,CC2530 module and GPRS module.The network layer is the link between the acquisition layer and the application layer.The data sent by the gateway is transmitted to the cloud server by using GPRS.According to the user’s needs,the application layer adopts the configuration programming interface.The interface has data display function,management authority function,history recording function and irrigation control,etc.The collected environmental data will be displayed on the interface,and the farmers can change the planting strategy according to the crops.In the data collection,the Kalman filtering algorithm is used for data fusion.The collected data is optimized by the algorithm which makes the transmitted data more accurate and reduces consumes on the wireless node.The system is experimentally verified by setting up an experimental platform.The experiment proves that the system can realize the accurate collection of the agricultural greenhouse environment and the control function of the equipment.The system is stable in operation,low in cost and easy to operate.It is worthy of popularization and application.
