Design And Implementation Of Agricultural Information Acquisition System Based On IOS

Traditional agriculture is inefficient and cannot be monitored comprehensively.But Agricultural Internet of Things(Ag-IoT)have achieved effective monitoring of agricultural production information,which improvement of agricultural productivity.The agricultural information collection has a positive significance to the system based on iOS has been designed and implemented,which is a specific Application of Agricultural Internet of Things,the system realizes the online high-precision measurement and real-time acquisition of environmental parameters of crop production through devices such as meteorological,water quality,soil and other types of sensors and RTU.The system has designed Web Service interface,users can browse real-time data and historical data of the sensors by iOS mobile devices,which can provide references for users in planting or disaster prevention.Data fusion technology is used to fuse sensor data,which effectively removes noise and improves data accuracy.The contents of this paper are as follows:1)The background and significance of the research are analyzed.The Application of Agricultural Internet of things is analyzed and summarized at home and abroad,and the related technologies of the system are introduced.2)The requirements of the system is analyzed,the software and hardware of the system are introduced,the architecture of the agricultural information collection system is designed,and the database design,the Web Service interface and the server process design are introduced.3)The design and implementation of iOS client are introduced in detail from design pattern,inter object communication scheme,data persistence,network layer design,Storyboard interface design and so on.4)This paper introduces the definition,classification and common data fusion method of data fusion,and selects the Calman filter and the weighted average filter based on the trust value to analyze the data fusion of the system data,which effectively removes noise and improves data accuracy.5)The Application of agricultural information collection system in engineering practice is introduced,mainly from web interface and data.
